The natural force in the Qi Sea immediately rotated quickly, and the excess impurities were removed, and about one-third of the impurities were discharged.

"Oh! After the natural power of my Qihai was purified, its power increased a lot!" Xu Yuntian said happily.

He stretched out his hand and grabbed a stalagmites of more than two meters high about ten meters in front of him. The force of nature quickly condensed into a palm and grabbed the stalagmites.

With a slight force, the stalagmites were taken out, and the Qingxuan liquid immediately spurted out. Xu Yuntian quickly took the cup to collect the Qingxuan liquid.

"Hehe! The power of nature should have increased by about two thousand. My current power is 12 thousand. Even a master in the late stage of the Wuwei Realm is no longer my opponent!" Xu Yuntian said happily.

After Xu Yuntian collected the Qingxuan liquid of a stalagmites, he continued to collect the stalagmites. About an hour later, he collected about a tank of Qingxuan liquid.

Then he entered the cave, which had a lot of space inside, and could fly in the airplane.

The top of the cave is stalactites, which are all kinds of strange and form various patterns.

There are also stalactites on the ground, and the largest stalactite is connected to the ground, like a stone pillar.

After walking along the cave for about two thousand meters, a huge light curtain appeared in front of it. This light curtain was very large, more than one thousand meters high and more than five hundred meters wide.

"Uh! This is a space barrier!" Xu Yuntian looked at the light curtain and said in surprise.

"There is actually a space barrier in the cave. Where does this space barrier lead to?" Xu Yuntian said in surprise.

He walked in front of the light curtain, reached out to touch the light curtain, and felt as if he was touching a spring, and his hand was bounced back.'

"Uh! What kind of space barrier is this? It can actually rebound!" Xu Yuntian said in surprise.

He looked up information about the ancestral spirit world, especially the relevant information about Heifengjian, and did not find any space barrier underground in Heifengjian.

However, judging from the spatial rules of the ancestral spirit world, this space barrier should be a barrier to another space. As for why the space barrier appears here, it is unknown who sets the space barrier.

Xu Yuntian walked along the space barrier until the end, and found nothing unusual.

Then he used his sword intention to attack the space barrier, and a sword flew out from his eyebrows. The sword fell on the space barrier, making a bang sound.

The space barrier was not damaged at all, and he couldn't help but be surprised and said, "Uh! This space barrier is too solid!"

He knew clearly that his sword intent was the power of his current sword intent, which was a sword intent of 12,000. Even a mountain would be cut off, and the space barrier was only shaken for a moment.

Xu Yuntian attacked the space barrier twice in a row, but the space barrier only shocked for a moment without any damage.

"Uh! To break this space barrier, I'm afraid it's necessary to have very advanced space laws!" Xu Yuntian frowned.

He gave up attacking the space barrier. With the cultivation level in front of him, he could not break the space barrier in front of him, unless he truly reached the late stage of the inaction state and merged with nine natural forces.

At that time, his power would probably exceed 30,000. At that time, the space barrier would definitely break under the attack of the sword intent.

Then Xu Yuntian released his spiritual consciousness, which could not penetrate the space barrier. Xu Yuntian finally left the cave helplessly.

After Xu Yuntian left the cave, he found a safe place and then entered the accelerated space on the first floor of the Holy Gate Tower to practice. He wanted to break through the realm of ghosting the sky and reach the realm of Wudao before leaving the Black Wind Stream.

Breaking through the realm of Wudao means integrating eight natural forces. It will take decades or even hundreds of years for ordinary people to break through this realm.

Because it is very difficult to merge the eight natural forces, the main difficulty is that the repulsive force of the eight natural forces is very high, especially when there is air force.

After staying in the time acceleration space for a year, Xu Yuntian still did not integrate the eight natural forces, which shows how difficult it is.

Xu Yuntian discovered a very serious problem, that is, after the natural force is strengthened, it is more difficult to integrate it, because the reinforced natural force repulsive force is greater.

"Uh! I knew this would have happened, I should have integrated eight natural forces and strengthened the natural power." Xu Yuntian frowned.

He really wanted to find a substance that can soften the eight natural forces, and it would be much easier to merge the natural forces under this substance.

He read the classics of the sects in the ancestral spirit world and soon found this fusion substance, called the soft fruit, which is the fruit that lives under the rules of nature's power.

According to the appearance description of any fruit, Xu Yuntian showed a look of surprise because he collected this kind of fruit, which was in the Xuankong ring.

He quickly took out the soft fruit, which looked like a fig. After taking a bite, the juice inside the fruit flowed into his mouth, quickly turning into a stream of air, and entering the sea of ​​air.

After the qi entered the Qihai, the eight natural forces of Qihai were immediately relieved. Xu Yuntian showed joy and said, "Oh! Soft fruit can really soften the repulsion of the eight natural forces!"

Xu Yuntian quickly took out two soft fruits and ate them, and then continued to practice. This time the repulsive power of the natural power was much smaller. Not long after, he merged eight natural powers to reach the early stage of the realm of inaction.

"I finally reached the early stage of the Wudao Realm!" Xu Yuntian said happily.

At this moment, his power increased by 5,000 again. The power he burst out now was 17,000, which was far beyond the late stage masters of Wuwei Realm.

Next, he continued to practice skills, especially sword intent. After he upgraded the sword intent to the heavenly level, he left the Black Wind Stream and went to Black Wind Valley.

The difficulty of improving the sword intent is more difficult than increasing the realm of natural power. Time accelerates into space for two years, but the sword intent has not been improved.

Xu Yuntian understood that this should be the reason why the cultivation level has not yet improved. If the sword intent needs to reach the heaven level, the cultivation level may have to reach the Wuwei realm.

Therefore, he gave up improving the sword spirit realm, but instead practiced Xuantian sword energy and instant sword skills. After three years of practice, Xu Yuntian practiced to the eighth level of Xuantian sword energy.

The eighth level of Xuantian sword energy is even more powerful than the holy-level sword intent, and it is a sword skill for group attacks. After one sword, countless sword energy flew across the board.

As for the sword skills in an instant, they have great progress. Because of the power of space, the sword skills are imprisoned with space. The moment they take action, the opponent is imprisoned by space, watching the sword attack, unable to dodge and defend.

Suddenly the Holy Gate Tower shook, and Xu Yuntian found that the third floor of the Holy Gate Tower was loose. He said curiously: "Oh! The third floor of the Holy Gate Tower is about to be opened! What's the third floor?"

After leaving time, he accelerated into space. Xu Yuntian walked to the second floor of the Holy Gate Tower and saw that the space barrier on the third floor was opened. He immediately followed the stairs and entered the third floor of the Holy Gate Tower.

The space of the third Holy Gate Tower is a little smaller than that of the second floor. There is a golden sword floating inside, and there are two doors.

One door says the door of space, and the other door says the door of time, and the door is closed.
Chapter completed!
