Qi Zhiheng absorbed a large amount of this corrosive substance and introduced it into his body to begin body tempering.

While absorbing the power of corrosion, he did not stay in one place. He killed monsters while absorbing the power of corrosion.

After gradually adapting to this corrosive force, he moved towards the innermost area.

The deeper you go, the more powerful the monsters inside will be. At the same time, after defeating these monsters, the more demonic energy you will obtain.

The central area was teeming with demonic creatures. Qi Zhiheng didn't believe that the demonic cultivators outside had his abilities to enter such a deep area, so it was highly likely that all the demonic creatures in this Land of Ten Thousand Demons were converging on the center.

This must be the case because the center has something that attracts them.

Similarly, Qi Zhiheng was also very interested in this.

Once you reach Qi Zhiheng's current location, virtually no demonic cultivators can get in; they would probably be corrupted in the outer areas.

As more and more monsters appeared, Qi Zhiheng found it difficult to deal with them.

The demonic energy emanating from these demonic creatures was a great tonic for Qi Zhiheng, containing far fewer impurities than directly absorbing remnant souls. However, less quantity did not mean none.

Qi Zhiheng inevitably suffered some injuries while hunting demons, but the demons didn't fare any better. In the end, he killed a group of more than a dozen demons at the Tribulation Transcending stage.

Qi Zhiheng absorbed the demonic energy obtained from killing the demon.

Some of this demonic energy was absorbed by Qi Zhiheng, some was absorbed by the demons that Qi Zhiheng did not deal with immediately, and the rest was returned to this land of ten thousand demons.

After absorbing some of the demonic energy, Qi Zhiheng entered his own space.

The impurities contained in these demonic energy seeds need to be sorted out and eliminated, a process that will take a long time, and Qi Zhiheng does not intend to waste time outside.

After spending about a year in space to remove the impurities from his body, he went out again to kill monsters.

This cycle repeated itself, and in the blink of an eye, Qi Zhiheng had spent five years in the Land of Ten Thousand Demons.

Five years later, Qi Zhiheng finally reached the center of the Ten Thousand Demons Land and saw the main reason for its formation.

It was a large rock with countless holes all over its body. The holes were of different sizes and were irregular, but they covered almost the entire rock.

The corrosive energy escaped from these holes, which shows that this is the starting point of the Land of Ten Thousand Demons.

There are quite a few monsters in the outer areas, but there are no monsters to be seen inside.

Qi Zhiheng quickly discovered the reason. The corrosive gas ejected by the stone was far too corrosive. Even though the monsters were essentially the same source as the gas, they couldn't resist the corrosion.

He placed his hands above a hole, from which a continuous stream of gas sprayed onto Qi Zhiheng's hands. His hands were immediately corroded, becoming somewhat bloody and mangled, and even coated with a corrosive substance that he couldn't shake off. He withdrew his hands and used the "Five Elements Body Forging Technique" to absorb the corrosive substance adhering to his hands for body forging. He quickly absorbed the corrosive substance.

He looked at his left hand, which had been corroded to the bone, and suddenly smiled. It had been a long time since anything could harm him.

The injuries proved that his body could be further strengthened.

After taking a pill, the hand, which had become a skeleton, began to regrow flesh and blood.

Qi Zhiheng approached the stone again, but this time he did not touch it directly with his hands. Instead, he directly absorbed the corrosive energy around it.

As soon as the corrosive energy entered his body, he felt a series of stinging pains in his meridians. It was a feeling of being in place, which did not make Qi Zhiheng back down, but instead aroused a hidden excitement in his heart.

After three days, he had adapted to the corrosive energy and moved closer.

Qi Zhiheng absorbed the corrosive energy day and night on the side of the stone. In less than three months, the energy on the stone seemed to be exhausted, and the corrosive energy it emitted seemed to have decreased significantly.

Qi Zhiheng was somewhat unsatisfied and moved closer. Now, even direct contact with these corrosive energies could no longer cause any harm to his body.

He placed his hand directly on the stone and began to absorb the energy.

The stone seemed to be afraid of Qi Zhiheng and actually shook slightly. Qi Zhiheng forcibly suppressed it and prevented it from escaping.

The stone quickly spit out a bunch of things. Qi Zhiheng took a look and found that they were some black crystal-like objects that could directly absorb the corrosive energy inside.

Qi Zhiheng was very pleased with its contribution, but he had no intention of letting it go. After accepting the black crystal, he absorbed the corrosive energy from the large stone into his body, storing it there. He had no intention of absorbing all the corrosive energy from the stone. If he absorbed all the energy, the Land of Ten Thousand Demons would probably cease to exist. His goal was to improve his own strength, not to eliminate the cultivation ground for the demon cultivators.

After absorbing most of the energy of the stone, Qi Zhiheng said: "Okay, you don't have to run away. I don't plan to get rid of you." After all, he had accepted bribes from the big stone, so he shouldn't be too ruthless.

The stone seemed to understand his words, and its trembling body stopped.

Qi Zhiheng flashed into the space in an instant. He had absorbed a large amount of energy during this period. His cultivation had entered the middle stage of the Tribulation Crossing Period. There was still a lot of energy that had not been absorbed in his body. He needed some time to convert all the energy into body-building power and then into his own cultivation.

A month later, Qi Zhiheng left the Land of Ten Thousand Demons.

The stone sensed Qi Zhiheng's departure and was so happy it almost jumped for joy.

Qi Zhiheng was unaware of Da Shitou's thoughts. At this moment, he was preparing to return to Shengxian City for a visit. As a city lord, his behavior of not returning for several years was extremely irresponsible.

It seemed like the last round of the City Lord Exchange Competition was over. Qi Zhiheng slapped his head. His thirst for cultivation had been so intense recently that he had basically forgotten about unimportant things. The City Lord Exchange Conference was one of those "unimportant things"...

When Qi Zhiheng returned to the city, he saw his original team and felt relieved.

A third-rate city, the city lord is a cultivator in the Tribulation Crossing Stage. Which Mahayana Stage cultivator dares to challenge a cultivator in the Tribulation Crossing Stage?

Even if they weren't in the Tribulation Transcending stage, they wouldn't have the guts. Who knows if Qi Zhiheng would come back to settle scores later?

It wasn't uncommon for a Mahayana cultivator to casually retreat for decades or even hundreds of years. This led to the development of a solution to replace the city lord in the battle: in the absence of the city lord, the deputy city lord could completely fill in. Chu Huaifeng, I'm standing there. Even the city lords of first- and second-tier cities wouldn't dare act rashly, and Shengxian City naturally survived.

When Qi Zhiheng returned to the city, there had been many changes, but fortunately, they were all changes from the original second-class level, so the Dao did not feel unfamiliar to Qi Zhiheng.

“Father!” Erbao stood on the city wall and waved to Qi Zhiheng with a happy smile on his face.

Qi Zhiheng smiled and nodded at him. Next to Erbao were Dabao and Sanbao. They saw Qi Zhiheng waving at him as well.

The three brothers hurried down the city wall to welcome Qi Zhiheng back.

"Father, how is your cultivation going?" Erbao was very concerned about Qi Zhiheng's cultivation.

Qi Zhiheng and his three sons walked in while answering, "It's already the middle stage of the Tribulation Crossing Stage, but it's not far from the late stage either."

Erbao asked cautiously, "Then when do you think you can ascend?" Although he didn't ask at the time, he was indeed worried about Yang Yitian's sudden ascension. However, no one could answer why his father ascended directly.

It's not that he didn't want to ask Qi Zhiheng, but Qi Zhiheng's condition was obviously not good during that time. Asking rashly would only bring more burden to him, and it might even cause him to have inner demons.

Now that so much time has passed, Qi Zhiheng has calmed down. Erbao naturally wants to know when his father will ascend to the Immortal Realm to find his father and ask him for clarification.

Qi Zhiheng said with certainty, "Within ten years."

Ten years was the deadline he set; he no longer had the patience to stay in the world of cultivation.

Chu Huaifeng reported some of the city's situation to him, but Qi Zhiheng's mind was no longer on that, so he asked, "Are you interested in becoming the city lord?"

Chu Huaifeng asked with some surprise, "You want me to be the city lord?" He knew that Qi Zhiheng was looking for a way to ascend, but ascension was not such a simple matter. At first, he also thought it was impossible, but now that Qi Zhiheng had spent less than five years to go from the early stage of the Tribulation Transcending Realm to the point where he was about to enter the late stage of the Tribulation Transcending Realm, how could he still maintain his previous idea?

Qi Zhiheng nodded and said, "Perhaps I won't be able to stay here for a few more years. Even if I wait here for dozens or hundreds of years, I won't stay in the city for a long time. You have taken good care of the city over the years. I think you should be able to become a good city lord."

Chu Huaifeng laughed and said, "City Lord, although you are not here, there are still many members of the Qi family. Why don't you ask if any of your family members want to be the city lord?"

Qi Zhiheng shook his head and said, "They probably don't want to be one."

Chu Huaifeng, however, disagreed, saying, "That's not right. You haven't even asked yet, how do you know they're unwilling?"

"They should focus on cultivation and ascend to immortality as soon as possible. There's no need to waste energy managing a force. They'll ascend sooner or later anyway, so having a city is useless. I'll create a better environment for them in the Immortal Realm," Qi Zhiheng replied.

Chu Huaifeng: "..." The Qi family doesn't waste their energy on trivial matters, so he should be the one wasting his energy, right?

Chu Huaifeng: "I'll be the city lord!"
