The Martial Arts Administration, being an opponent of the Black Tower, naturally considered Qin Han Chu an adversary upon his joining the latter. It was also reasonable for the Administration to seek Qin Han Chu's early elimination to weaken their rival.
"Don't worry, they won't," the Black Tower executive said with a smile. "As long as you don't use martial arts in front of ordinary people, they won't make a move against you."
Qin Han Chu asked, puzzled, "Why? Is there an agreement between your organizations?"
"Indeed," the Black Tower executive replied. "If the Martial Arts Administration were to kill Black Tower martial artists without cause, we would plunge this world into chaos."
"Impressive. It seems your strength is indeed formidable."
The ability to instill fear in the Martial Arts Administration demonstrated the formidable strength of the Black Tower.
"However, I must remind you that there are two exceptions."
"First, if you kill the relatives of a Martial Arts Administration powerhouse, they might seek revenge against you in a personal capacity."
"Second, if you violate the agreement between the two factions."
"I will give you a copy of the agreement later. This is the only contractual rule that our Black Tower martial artists must follow."
Qin Han Chu nodded. "Alright."
...
The next morning, a helicopter landed in the courtyard of Qin Han Chu's villa.
As Qin Han Chu walked out of the villa, he saw the Black Tower executive sitting in the helicopter, smiling and saying, "Let's go."
After Qin Han Chu boarded the helicopter, they headed towards the airport.
At the airport, a Kun-class transport warplane was ready for departure.
As Qin Han Chu and the Black Tower executive boarded the warplane, it took off immediately.
"Headquarters is very far from here, so you can cultivate first," the Black Tower executive said with a smile as he fastened his seatbelt. "It will take about half a month to get there."
The warplane was quite fast, yet it still took half a month, indicating the immense distance.
Qin Han Chu did not ask further. He fastened his seatbelt and began to cultivate.
Even though they were on a warplane, food and drinks were provided, so Qin Han Chu wouldn't go hungry.
After half a month of cultivation, Qin Han Chu's strength had reached the middle stage of Grandmaster.
"Look at the mountain cave ahead," the Black Tower executive said at this moment.
Qin Han Chu looked out the window and saw that they were currently amidst a range of snow-capped mountains.
Directly in front of the warplane stood a towering peak that reached into the clouds.
At the base of the peak was a colossal mountain cave.
The cave resembled the gaping maw of a colossal mythical beast.
"This is the headquarters?" Qin Han Chu asked.
The Black Tower executive shook his head. "This place is called the Gate of Hell, or the Gate of the Earth's Core!"
"What do you mean?"
"This is the entrance to the underground world."
Upon receiving the Black Tower executive's answer, surprise flickered in Qin Han Chu's eyes.
Could it be a world portal?
While the two were speaking, the warplane entered the mountain cave.
The cave was brightly lit, and the passage walls were lined with countless cannons.
Any warplane entering without authorization would undoubtedly be blasted to pieces by these cannons.
After about half an hour, the warplane began to dive downwards.
After flying for a full three days and three nights, the scenery ahead suddenly opened up.
Immediately, Qin Han Chu realized they were in the air.
The sky in this world was vibrant with a thousand colors, but there were no clouds, only hard rock and earth.
There were even inverted mountains.
This was not another world, but the very core of the earth.
It was at this moment that Qin Han Chu suddenly felt a sense of summons.
His divine seal was located here!
Or rather, this subterranean world was created by his divine seal.
Despite the summoning sensation, it was too faint for him to pinpoint the location of the divine seal.
"Is the server for God's War also here?" Qin Han Chu asked.
"That's right, the server for God's War is here. See that giant tree connecting heaven and earth? That is the central core of the server."
Qin Han Chu turned his head and saw, in the distant sky, a phantom tree silhouette that supported the heavens and the earth.
If that was the central core of God's War, then Qin Han Chu's divine seal must be located at the position of that giant tree.
"It's the central core?" Qin Han Chu's expression was one of disbelief.
The Black Tower executive replied, "This is the World Tree, also known as the Tree of Creation. Legend has it that the earliest martial arts originated from it!"
"How can a tree be the origin of martial arts?" Qin Han Chu feigned incomprehension.
"For countless years, people have been studying it, but we have never been able to obtain any new martial arts inheritances from it."
"Everything in God's War seems to be from another epoch it has witnessed."
"That was an epoch of flourishing martial arts, where powerful martial artists could move mountains and fill seas, creating their own worlds."
As he spoke these words, a look of yearning filled the Black Tower executive's eyes.
As a martial artist, he too wished to possess the power of the figures in God's War.
Qin Han Chu, while seemingly awestruck, was actually contemplating the exact location of his divine seal.
Could it be within this World Tree?
Or perhaps below the World Tree?
Though Qin Han Chu had now reached Grandmaster, he likely wouldn't be able to move the World Tree.
However, it would be difficult for Qin Han Chu to fuse his divine seal through the World Tree unless he reached the Spirit Realm and birthed spiritual consciousness.
"Can we go and see the World Tree?" Qin Han Chu asked after a long pause.
The Black Tower executive shook his head. "It's difficult to approach the World Tree now."
"Why?"
"Because the feral beasts have become an obstacle for us."
As soon as the Black Tower executive finished speaking, a strange flying creature the size of a house suddenly approached the Kun-class warplane.
The Kun-class warplane immediately fired its cannons!
Despite being hit by the artillery, the flying creature did not die. It merely let out a scream and fled into the distance.
To withstand artillery fire with its physical body, this was the combat power of a peak Grandmaster.
"There are many terrifying feral beasts here, but also many precious medicinal herbs. Some of these herbs can even directly enhance our strength; they are very valuable."
Qin Han Chu secretly rejoiced. This place was perfect for him!
As long as he had enough medicinal herbs, his strength could rapidly ascend.
"Does the Martial Arts Administration also have a base here?" Qin Han Chu asked.
"Both factions jointly manage this subterranean city!"
As the Black Tower executive spoke, the warplane flew over a high mountain.
Immediately, Qin Han Chu saw a magnificent castle complex appear before him.
These castles were connected, appearing very grand and spectacular.
Clearly, this was the subterranean city the Black Tower executive had mentioned.
As the warplane descended, Qin Han Chu observed people coming and going within these castles.
In terms of scale and foot traffic, this subterranean city was no less impressive than a large city in the outside world.
"There are a total of one thousand castles here. Five hundred belong to the Martial Arts Administration, and five hundred belong to the Black Tower."
"Divided by the canyon river in the middle, the castles to the east belong to the Black Tower faction."
"Apart from the fact that everyone here is a martial artist, there isn't much difference from the outside world," the Black Tower executive introduced to Qin Han Chu.
