After a year of conditioning, the physical condition of the great-grandmother and Elder Lu Song had improved several times over.
What Qin Han Chu needed to do now was to consolidate their advancements.
Qin Han Chu did not know much about the Martial King realm, so he needed to observe for a long time and formulate a plan.
During this period, Qin Han Chu also needed to improve his own strength.
The stronger his strength, the more adept he would become at controlling his Gang Jin.
This was also an important factor in increasing the success rate.
Not long after the three arrived at the ancestral land, the clan's elites carried a giant cauldron.
This bronze giant cauldron was over three meters tall and was inscribed with ancient runes.
Boom!
As everyone released their grip, the cauldron crashed onto the ground with a rumble.
Under Qin Han Chu's command, buckets of mountain spring water were poured into the giant cauldron.
With the water ready, the crowd began to light a fire beneath the cauldron.
Qin Han Chu stood by the side, frequently tossing some medicinal herbs into the giant cauldron.
After simmering for a full eight hours, the medicinal concoction in the giant cauldron had become very viscous.
Only then did Qin Han Chu instruct people to temporarily extinguish the fire.
After cooling for an hour, Qin Han Chu looked at his great-grandmother and Elder Lu Song: "Both of you, you can change your clothes and get in."
The two removed their outer garments and entered the giant cauldron wearing only "swimsuits."
Although it had been left for an hour, the medicinal paste still maintained a high temperature.
The two frowned, enduring the burning torment.
"Prepare the charcoal," Qin Han Chu said to the clansmen beside him.
Soon, pieces of glowing charcoal were placed beneath the giant cauldron.
With the heat from the charcoal, the medicinal paste in the cauldron would maintain its temperature and release its medicinal effects.
Leaving the task to the clansmen, Qin Han Chu went to the stone door and sat down cross-legged.
Time passed in a flash, and two months went by.
On this day, a rumbling sound echoed from within Qin Han Chu's body.
The sound grew louder and louder, even startling the Qin clansmen in the distance.
When they looked at Qin Han Chu, they saw streams of terrifying Gang Jin transforming into shockwaves that spread outwards.
Under the force of these shockwaves, trees more than ten meters away trembled violently.
"Grandmaster peak!"
"The Clan Leader has actually reached the peak of the Grandmaster realm!"
The Qin clansmen present were all absolutely loyal. They had long known that the Primordial Medical Scripture was in Qin Han Chu's possession.
They also had some understanding of Qin Han Chu's true strength.
But they never expected Qin Han Chu to break through so quickly again.
Grandmaster peak was definitely the strength of a top-tier expert.
In this world, currently, only the leader of the Dragon Alliance was in the Martial King realm.
After a long while, Qin Han Chu finally opened his eyes with a smile.
Standing up, Qin Han Chu went to the side of the large cauldron.
"Congratulations to the Clan Leader for reaching Grandmaster peak," all the clansmen congratulated him.
Qin Han Chu smiled and said, "With the help of the Primordial Medical Scripture, the Grandmaster realm will no longer be our limit."
Upon hearing this, everyone became excited.
At this moment, the great-grandmother and Elder Lu Song were still soaking in the giant cauldron.
Of course, they were not in it all the time.
Over these two months, Qin Han Chu had changed the medicinal bath for the two six times.
Under the consolidation of the medicinal bath, the two had already reached a perfect state.
"Great-grandmother, Elder Lu Song, you can come out now," Qin Han Chu said.
Hearing this, the two then gracefully landed.
"You two go back and wash up first, and then begin your breakthrough."
After speaking, Qin Han Chu took off his top and jumped into the giant cauldron.
The medicinal effects had not been fully absorbed yet, so it would be a waste not to use them.
Two hours later, the great-grandmother and the two returned.
By then, Qin Han Chu had already changed into clean clothes.
"Who wants to go first?"
"This is also my first time helping a Grandmaster peak breakthrough, so the first one is a guinea pig."
Qin Han Chu said frankly.
Elder Lu Song said, "I'll go first."
"Great-grandmother, please sit aside and regulate your breathing to maintain your best state," Qin Han Chu said.
"Alright." The great-grandmother walked to the side and sat down cross-legged.
Under Qin Han Chu's instructions, Elder Lu Song sat down cross-legged.
He first performed acupuncture on Elder Lu Song, and then sat down cross-legged behind him.
Placing his palms on Elder Lu Song's back, he said, "Elder Lu Song, circulate your Gang Jin according to my guidance."
Although Qin Han Chu had never seen the Martial King realm, he had already guessed the key to the breakthrough.
As long as the Mingmen acupoint and Guanyuan acupoint were opened, the Ren and Du meridians would be unblocked.
This should be the key to impacting the Martial King realm.
Elder Lu Song's willingness to be the guinea pig was admirable.
Under Qin Han Chu's guidance, Elder Lu Song's Gang Jin began to gather.
Qin Han Chu had sealed off numerous meridians, and Elder Lu Song's Gang Jin was like a stream converging into a river.
As the Gang Jin became more robust, Elder Lu Song's main meridians bore immense pressure.
Fortunately, his meridians were extremely tough after Qin Han Chu's reinforcement, and they could withstand it completely.
Under Qin Han Chu's guidance, the powerful Gang Jin surged towards the Mingmen acupoint.
Bang!
The Gang Jin fiercely struck the Mingmen acupoint, and the Mingmen acupoint, under its impact, slowly opened like a great gate.
As it opened, the Gang Jin surged into it like water from a breached dam.
Under the impact of the Gang Jin, the Mingmen acupoint was completely opened.
This process was very painful, but Elder Lu Song endured it.
Under Qin Han Chu's guidance, the Gang Jin rushed towards the Guanyuan acupoint.
With another booming sound, the Guanyuan acupoint was also broken through.
As the Guanyuan acupoint became unblocked, Qin Han Chu suddenly felt a suction force emanating from Elder Lu Song's body.
Qin Han Chu's Gang Jin, uncontrolled, flowed into Elder Lu Song's body.
This situation startled Qin Han Chu, but he did not withdraw immediately.
Qin Han Chu's Gang Jin flowed with the suction force, and then gathered in Elder Lu Song's lower dantian.
Only then did Qin Han Chu forcefully sever his connection with Elder Lu Song.
With the Ren and Du meridians unblocked, the lower dantian had become a core!
It was like a vortex, accumulating the Gang Jin within the body.
On Elder Lu Song's face, Qin Han Chu saw an excited expression.
He knew that Elder Lu Song had succeeded.
Qin Han Chu had initially thought this process would be very dangerous, but it seemed that was not the case.
As long as the foundation was sufficient, a little guidance would lead to a natural progression.
"Did it succeed?" the great-grandmother asked nervously.
Qin Han Chu nodded, "Yes, it should have succeeded. I will now guide you through the breakthrough."
After speaking, Qin Han Chu removed the acupuncture needles from Elder Lu Song.
The great-grandmother was very excited at this moment. She never thought she would have the opportunity to step into the Martial King realm in her lifetime.
"Stabilize your mind," Qin Han Chu said after sterilizing the acupuncture needles.
The great-grandmother took a deep breath, calming her emotions.
After the acupuncture was finished, Qin Han Chu began to guide the great-grandmother through the breakthrough.
Just like with Elder Lu Song, the entire process went very smoothly.
In less than half an hour, the great-grandmother also completed her breakthrough.
Thus, the Qin clan now had two Martial King realm experts.
With these two guarding the clan, even if the Dragon Alliance leader himself came, they would not gain any advantage.
