Of course, this kind of time cannot last for too long. With Jiang Fan's current state of half-step Human Emperor and his background, he can only last for a hundred days.

After recovering to its peak, Jiang Fan took action to refine and collected a new Dark Sacrifice Tower.

A very surprising situation occurred. The speed at which he collected the second Dark Sacrifice Tower was five hours faster than before, and it took only fifteen hours to collect it successfully.

After exploring his own situation, Jiang Fan quickly discovered the reason. This is because after the first Dark Sacrifice Tower appeared, it existed in the Immortal Sword Seal, and could independently communicate with the mysterious dark world, thereby directly passing the vitality of the dark world into the Immortal Sword Seal.

After the Immortal Sword Seal was integrated into the dark attribute energy, it even changed without realizing it, just like refining some god-level weapons.

In the depths of the void inside the Immortal Sword Seal, the war sword also produced an invisible transformation. In the past, this war sword reached a length of 10 million meters, and essentially transformed into a god-level war sword. However, now it has been extended by 100,000 meters again, and it is still undergoing continuous transformation without realizing it.

If this continues, this battle sword may be close to... or even transformed into a human emperor's killing weapon.

The elixir that surpasses the god-level superb level is called the Four-Pole Emperor Pill, and the same is true for the weapons that surpass the god-level superb level, and are also the Four-Pole Emperor soldiers, namely: the Human Emperor Killing Tool, the Earth Emperor Killing Tool, the Emperor Killing Tool, and the Emperor Killing Tool.

If the sword inside the Immortal Sword Seal transforms into a human emperor's killing weapon, then his combat power will skyrocket to an extremely terrifying level. At that time, even if his realm does not undergo a transformation and remains in the half-step human emperor's realm, he can directly kill with one sword without borrowing any external force or means. A strong man standing at the peak of the Human Emperor's Great Realm will be killed by himself.

Jiang Fan suspected that the war sword inside the Immortal Sword Seal was itself another form of the Immortal Sword Seal. The two were originally one, but the Immortal Sword Seal gave birth to the internal sword, which was similar to a kind of sword body.

The Immortal Sword Seal is equivalent to one's own body, and the constantly transforming battle sword inside the Immortal Sword Seal is equivalent to the natal sword fetus in one's own body. As long as one continues to practice, the natal sword fetus in one's own body will continue to become stronger. As long as one continues to bless the Immortal Sword Seal, or allows it to continuously refine many extremely precious materials, the quality of the war sword inside the Immortal Sword Seal will continue to improve.

Therefore, when a Dark Sacrifice Tower already exists inside the Immortal Sword Seal, it will independently absorb the power of the Dark World and replenish it into the Immortal Sword Seal, making the essence of the Immortal Sword Seal stronger. After the essence becomes stronger, your foundation will become stronger, and the speed of refining other Dark Sacrifice Towers will be faster.

This mysterious and mysterious power and the changes between vitality are sometimes unpredictable even for Jiang Fan, who was at the peak of his previous life, not to mention that he has never risen after his rebirth.

The so-called Wuji martial arts, no one has reached its true limit since ancient times. Even if it is a high-ranking emperor, the only emperor, can only live for ten thousand years. If anyone can thoroughly understand the essence of martial arts and cultivation and can truly control everything, then it will be possible to achieve the theoretical existence... immortality, immortality and immortality.

Countless thoughts surged through his mind in just a short moment. Jiang Fan did not rest, but instead took action to suppress it with the Immortal Sword Seal and collect the third Dark Sacrifice Tower.

As time passed, Jiang Fan almost stayed in this special space below the Two Realms Peaks and never went out. He passed like this for ten days.

In the ten days, except for a very small number of times to recover from meditation, he devoted all his energy to successfully put thirty dark sacrifice towers into the inner void of the Immortal Sword Seal.

He has now collected a Dark Sacrifice Tower and has reached four hours.

Because the thirty dark sacrificial towers inside the Immortal Sword Seal are constantly absorbing vitality from thirty different dark worlds, replenishing the Immortal Sword Seal, and enhancing the body of the Immortal Sword Seal, making this speed faster and faster.

Even Jiang Fan himself can only control one Dark Sacrifice Tower at one time to practice. However, after these Dark Sacrifice Towers enter the Immortal Sword Seal, they can independently open the portals of different dark worlds and absorb the vital energy from it. This is a very mysterious state. Although the speed of self-absorbing vital energy is not very fast, at least it can be in this state all the time. This is very pleasant. Jiang Fan will not need to think about how to get some killing weapons every day for the Immortal Sword Seal to be refined. On the one hand, it is troublesome, and on the other hand, the top resources are limited after all. If all of them are refined by the Immortal Sword Seal, it would be a pity.

The Immortal Sword Seal is like a creature who can practice independently, and has less "care" from Jiang Fan.

Just after collecting the 30th Dark Sacrifice Tower, Jiang Fan felt powerful auras appearing on the Two Realms Mountains.

However, this aura is a kind of aura emitted by the powerful nature of a warrior and his talent has nothing to do with the realm. It is not that there are any great figures with extremely high realm coming, but that are coming from several martial arts geniuses.

Sensing all this, Jiang Fan smiled slightly, then left the place directly, and soon appeared on the top of the Two Realms Mountain.

"Long time no see!" Jiang Fan looked at the four people who appeared in front of him.

The Four Sons of God!

The four people I met in the Shenxu Realm in the past, or the four sword geniuses who were almost hunted by Jiang Fan in the Shenxu Realm, came here today.

In the Shenxu Realm, the four sons of the God-killing God are boundlessly arrogant, which is a fear of many geniuses who have come from the Shenzhou. However, in front of Jiang Fan, they could only kneel down and put away all their arrogance. These four people were all carrying sword bodies, and one of them even had a natal sword fetus. Unfortunately, his natal sword fetus was broken by Jiang Fan in the Shenxu Realm and was almost destroyed.

Jiang Fan once said that if you want to recover, these four people must go to the Demon Academy to find them. It seems that they came to the Prehistoric Sword Sect before they could appear in the Demon Academy.

With his eyes wide open, Jiang Fan looked at the four people in front of him, as if he was looking at four uncensored jades, and he could use this to carve a peerless divine object...

"We are here to find you. I don't know what we need to do to help you help me restore my natal sword fetus." Among the four sons of the God-killing God, the one whose natal sword fetus was broken by Jiang Fan's eyes were complicated and he spoke in a deep voice.
