This dark elemental spirit is only half a step away from the Totem level. We can apply for a legendary-grade resource to help it break through.
As for the fire and wind elemental spirits, improving them is a bit troublesome, but we will do our best to find a way for you.
Also, don't worry too much. When the time comes, we will also apply for a titled legendary beast tamer to protect your safety when you enter the Nether Ghost King Realm," Professor Ye Lu said.
Zheng Dong, however, paid no mind.
The Nether Ghost King Realm was too dangerous, and a titled legendary beast tamer might not be able to fully protect him.
He might have to rely on himself then.
Afterward, the experiments continued.
Professor Xie Gaoyang and the others did not dare to increase the concentration of the various bloodline powers within Zheng Dong's body for the time being.
Instead, they took Zheng Dong to another laboratory.
The Supergravity Magnetic Field Laboratory.
Here, gravity and magnetic fields could be adjusted at any time, large or small, even reaching a state of weightlessness.
Additionally, an ultra-strong magnetic field could be generated.
By stimulating Zheng Dong's body with the magnetic field, it would further absorb and integrate the various resources within him.
This would help Zheng Dong strengthen his body.
At the same time, based on Zheng Dong's physical condition, he would be supplemented with corresponding nutrient solutions or life essence.
He would also be given resources like the Blood Man Fruit to further enhance his physical foundation.
Zheng Dong underwent this type of experiment for over ten hours a day.
It was equivalent to a different kind of training.
The effects were also very significant.
Zheng Dong's physical indicators had reached the level of most legendary beast tamers.
However, he was still far from reaching the level of a divine-grade extraordinary creature.
And the higher he climbed, the more difficult it felt.
After less than twenty days of experiments, Zheng Dong felt that the supergravity laboratory's effect on his body was no longer significant.
Subsequently, Professor Xie Gaoyang and the others adjusted the experimental plan again.
This time, it required entering a special relic space.
The relic space possessed strong spatial elemental energy, which would form spatial elemental energy flows, and even spatial storms.
A spatial electromagnetic laboratory was built here.
The spatial and electromagnetic forces within the laboratory could further enhance Zheng Dong's physical strength.
Zheng Dong stayed in this relic space for over a month.
His physical strength had reached the peak of a legendary beast tamer.
It was completely comparable to the physical strength of the legendary Long Zhen.
With this, Professor Xie Gaoyang and the others could not further enhance Zheng Dong's physical strength independently for the time being.
Unless they increased the concentration of bloodlines from divine-grade extraordinary creatures like the Azure Dragon and Vermilion Bird within Zheng Dong's body, there was no way to continue improving.
However, with less than two months left until the time required by the spirit of the Resentful Soul Relic Space, Zheng Dong could no longer participate in experiments.
They were worried that increasing the bloodline concentration would disrupt the balance within Zheng Dong's body.
In that case, Zheng Dong would definitely be injured.
It would be difficult to recover and re-establish the balance of bloodline powers within his body after being injured, likely taking a long time.
Thus, Zheng Dong could temporarily leave the experimental base and act freely.
However, he had to return before entering the Nether Ghost King Realm to join the titled legendary beast tamers arranged by the Fire God Sect.
Zheng Dong did not object to this.
Having an extra helper was better than acting alone.
However, Zheng Dong did not rush to leave.
After returning to his room, he re-entered the mythical-grade relic space and used the Ten Thousand Year Fruit.
The Ten Thousand Year Fruit tasted a bit sour and was not very delicious.
However, after eating it, Zheng Dong felt a special power surge through his body.
Instantly, he felt much more relaxed.
If nothing unexpected happened, he felt he could live for seventy to eighty more years.
As he slowly refined the Ten Thousand Year Fruit.
His physical strength also increased again.
Although the increase was not as significant as before.
It still improved considerably.
His strong physique was very close to the quasi-divine level.
It even surpassed the physical strength of the legendary Long Zhen.
Afterward, Zheng Dong left the experimental base and returned to Rongcheng.
He visited Shen Bing and Shen Xue's home again.
After all, he had left in a hurry before and had not informed Shen Jiuxiao.
Shen Jiuxiao had also been away for several months to help Shen Bing and Shen Xue resolve the Resentful Ghost Ring, only returning home about twenty days ago.
She then discovered that the house was covered in a layer of dust and that Shen Bing and Shen Xue were nowhere to be found.
This made Shen Jiuxiao extremely anxious.
She frantically sent messages to Shen Bing and Shen Xue.
But no one ever replied.
She assumed that Shen Bing and Shen Xue had already entered the Nether Ghost King Realm.
She was so scared that she couldn't eat.
This time, she sought help from many people.
She even mobilized everyone she could in the Spirit God Sect to find a solution.
Unfortunately, the answers she received were almost all negative.
And for the remaining possibilities, there was little confidence.
Hearing the door open, Shen Jiuxiao rushed out of her room, hoping it was Shen Bing and Shen Xue.
Seeing the two sisters, she was stunned, then ran downstairs and hugged Shen Bing and Shen Xue without regard for her appearance.
"Where did you go? You didn't even tell me."
Without waiting for Shen Bing and Shen Xue to explain.
Shen Jiuxiao looked at Zheng Dong and couldn't help but scold him.
"You brat, did you abduct my daughters?"
Zheng Dong shook his head.
"Auntie, you're overthinking it."
Shen Jiuxiao pulled Shen Bing and Shen Xue behind her, staring at Zheng Dong with a cold expression.
Zheng Dong immediately felt as if he were being stared at by a poisonous snake.
Immediately after, Shen Jiuxiao kicked Zheng Dong.
"Who's your auntie? Am I that old?"
Shen Jiuxiao's kick was fast and fierce, aimed directly at Zheng Dong's groin.
This was a kick intended to render Zheng Dong infertile.
Faintly, Zheng Dong even saw a phoenix phantom appear on Shen Jiuxiao.
Zheng Dong was startled.
He hadn't expected Shen Jiuxiao to be so powerful.
Her attack power far surpassed that of most titled legendary beast tamers.
It was likely that Shen Jiuxiao's identity was not as simple as Shen Bing and Shen Xue had described.
Zheng Dong showed no fear.
Without using any bloodline powers, he reached out and grabbed Shen Jiuxiao's ankle.
No matter how hard Shen Jiuxiao tried, she couldn't move any further.
However, the situation was somewhat awkward.
Shen Jiuxiao was still wearing a nightgown.
It was longer than the one Zheng Dong had seen the first time.
But it couldn't hide her graceful figure.
Zheng Dong didn't know where to look.
He had no choice but to release Shen Jiuxiao's ankle.
Unexpectedly, Shen Jiuxiao threw a punch at him again.
Her fist was surrounded by black flames.
This was the Undying Netherflame possessed by the Undying Phoenix.
It was aimed directly at Zheng Dong's face.
If he were hit, Zheng Dong would likely be disfigured.
Zheng Dong frowned.
Although Shen Jiuxiao was Shen Bing and Shen Xue's mother.
Her relentless pursuit was a bit excessive.
"Auntie, we were just trying to find a way to resolve the Resentful Ghost Ring."
Zheng Dong explained while easily catching Shen Jiuxiao's fist with his hand.
Shen Jiuxiao was very surprised.
She had not expected Zheng Dong to easily block her attack.
He hadn't even summoned any of his spirit beasts.
This strength, among the new generation of beast tamers in Yanhuang, was probably second to none.
The reason she attacked was partly dissatisfaction with Zheng Dong and partly to test him.
Since she hadn't found a way to resolve the Resentful Ghost Ring, she planned to accompany Shen Bing and Shen Xue into the Nether Ghost King Realm herself.
To enter, she at least needed to know Zheng Dong's strength.
She didn't want to bring a burden.
She had initially thought a single kick would reveal Zheng Dong's depth, but he had easily neutralized it.
Then, she delivered another punch.
This was when she truly realized that Zheng Dong's strength was probably not inferior to hers.
At the same time, Shen Bing and Shen Xue, who were standing nearby, reacted.
They quickly stopped her.
"Mom, stop, don't hurt Zheng Dong."
"You ungrateful wretches, you're siding with outsiders before you're even married, and you never worry about your mother like this."
A flash of anger crossed Shen Jiuxiao's eyes.
She did not stop.
With a bang, scorching black flames surged from her entire body.
As if in response, a phoenix cry seemed to echo.
Instantly, Zheng Dong felt a tremendous force transmitted through his hand.
Shen Jiuxiao's fist easily broke free from his grasp.
Then, she struck at him with another palm.
Countless black flames gathered to form a massive Undying Nether Phoenix, flying towards him.
Zheng Dong felt that this attack was more ferocious than any before.
It was as if a overlord-level Undying Nether Phoenix was right in front of him.
Zheng Dong felt that his physical strength alone might not be enough to withstand Shen Jiuxiao.
He had no choice but to use his skills.
Immediately, Zheng Dong used Spatial Teleportation and appeared behind Shen Jiuxiao.
He intended to evade Shen Jiuxiao's attack.
Unexpectedly, Shen Jiuxiao reacted quickly.
She raised her leg and kicked at Zheng Dong.
Black flames gathered at her toes, forming another large Undying Nether Phoenix, seemingly intending to tear Zheng Dong apart.
Zheng Dong did not rush to counterattack.
He also wanted to test Shen Jiuxiao's strength.
So, he continued to dodge.
Using Spatial Blink, he moved outside the room.
The room was too small to be suitable for combat.
Unexpectedly, Shen Jiuxiao burst through the door the next second and pursued him.
Immediately after, Shen Bing and Shen Xue also ran out.
They wanted to stop her, but they couldn't hold Shen Jiuxiao back at all.
Moreover, they were very surprised.
They hadn't expected their mother to be so powerful in combat.
They had always thought their mother was just a support-type beast tamer.
"Sister, am I seeing things? Is this really Mom?" Shen Xue asked.
Shen Bing didn't say anything, only nodded.
She looked at Shen Jiuxiao, feeling both familiar and unfamiliar.
Then she looked at Zheng Dong.
She recalled the scene of her battle with Zheng Dong during the Rongcheng Rookie King Competition.
How did you improve so quickly? I can't keep up with you anymore.
The battle continued.
Zheng Dong and Shen Jiuxiao exchanged blows repeatedly.
They left the garden behind the villa in ruins.
Flowers and plants were burned everywhere.
Even the single fruit tree was broken by Shen Jiuxiao's punch and turned to ash under the burning black flames.
"Auntie, why don't you change your clothes?" Zheng Dong said.
Shen Jiuxiao then noticed that her nightgown had a tear in it at some point.
Revealing her fair and delicate skin.
Of course, she didn't care much about it.
She glared fiercely at Zheng Dong.
"You brat, just you wait, we'll continue this later."
Shen Jiuxiao turned and returned to the villa.
Shen Bing and Shen Xue walked over.
"Zheng Dong, are you okay!"
Shen Jiuxiao, who hadn't gone far, heard this and felt quite annoyed.
As expected, girls are more inclined to their own families.
Shen Bing and Shen Xue had never shown her such concern before.
However, Zheng Dong's strength was very satisfactory to her.
This gave her more confidence about entering the Nether Ghost King Realm.
It was just that Shen Bing and Shen Xue's strength still needed improvement.
She returned to her room, took off her nightgown, and changed into a red dress.
She came to the living room.
"You three, hurry up and come in. What are you doing standing outside?"
Outside the villa, Zheng Dong and the two sisters were stunned.
Then, they returned to the villa and also came to the living room.
"Sit down, everyone," Shen Jiuxiao said.
Her expression was calm, as if she had transformed into a different person.
Shen Bing and Shen Xue immediately breathed a sigh of relief.
Fortunately, they didn't start fighting again.
"I plan to enter the Nether Ghost King Realm with you," Shen Jiuxiao continued.
Shen Bing and Shen Xue's relaxed nerves tensed up again.
"Mom, please don't go. It's too dangerous there," Shen Bing said.
"Exactly, Mom, don't cause trouble," Shen Xue said.
"Who's causing trouble? I'm worried about you, so I'm going with you. To resolve the Resentful Ghost Ring on you, I lowered myself and begged everyone I know, but no one could guarantee a solution.
Since there was no other way, I had to go with you," Shen Jiuxiao said indignantly.
Shen Bing and Shen Xue fell silent.
They seemed very guilty.
"Don't worry, with my strength, I can definitely protect you. As for this brat, he'll have to fend for himself. If he dies, I won't care," Shen Jiuxiao said.
Zheng Dong didn't mind or get angry.
If Shen Jiuxiao went with them, and could protect Shen Bing and Shen Xue, it would be a good thing.
He was only afraid that the danger level of the Nether Ghost King Realm would far exceed their expectations.
"Also, you two, get ready. I'll take you somewhere later to improve your strength.
With your current state, running around all day, aren't you afraid that your mother will have no one to send her off when she dies in a hundred years?" Shen Jiuxiao continued.
Shen Bing and Shen Xue didn't need much preparation; they carried their belongings with them.
They were just very curious about where Shen Jiuxiao would take them.
Under Shen Jiuxiao's arrangement.
A private aircraft arrived above the villa.
The appearance of this aircraft was very different from an airplane; it resembled a flying saucer more.
It was more advanced than an airplane and was itself a mechanical spirit beast.
Its owner was also a beast tamer who earned money by piloting the aircraft.
He was also a member of the Spirit God Sect.
Then, the group boarded the aircraft and headed south.
They arrived at Ya City, the southernmost city in Yanhuang.
The weather here was hot.
Short sleeves could be worn all year round.
Led by Shen Jiuxiao, they entered a hidden relic space occupied by the Spirit God Sect.
This place was known as the Sea Cliff Relic Space.
It was a mythical-grade relic space, and the cultivation speed within it was eighteen times faster than in the outside world.
It was even slightly faster than the speed in the Abyss Relic Space.
Many people within the Spirit God Sect cultivated here.
With Shen Jiuxiao's status as a vice-leader in the Spirit God Sect, bringing Shen Bing and Shen Xue in was not a problem at all.
Of course, to prevent the Resentful Ghost Ring from erupting, Zheng Dong also entered with them.
With less than a month and a half remaining until the agreed time with the spirit of the Resentful Soul Relic Space, they had ample time to cultivate well.
Zheng Dong did not want to miss this opportunity to benefit.
He seized the time to improve himself and the strength of his spirit beasts like Ling'er.
