The last few levels are simply as difficult as climbing to the sky.

Even if it is just one level, it often takes a long time to accumulate to slowly climb up little by little.

That process was so difficult that it was a bit unimaginable, and the progress was too slow. Sometimes, no matter how hard you work, you can't even improve one level. That is the most helpless thing. Your own strength seems to be completely trapped here and cannot improve at all.

How difficult it is to be to reach the level of the land level secret book.

This is because of having dragon energy on your body. With such a powerful stimulation, your own strength is far beyond what ordinary people can compare to.

Even so, it is still quite difficult. You can imagine how difficult it is for ordinary players to practice this kind of secret book.

As for the Heavenly Level Secret Book? Forget it... that thing is simply inhuman level. Just that story of immortality has experienced a brief rapid improvement after experiencing the power of Long Yuan at the beginning. Apart from that, there is basically no progress.

In addition, for so long, Zhou Bo's focus has always been on the practice of the Nine Yin Scriptures. Since the End of the Heavenly Level Secret Book, the Eternal Life Art has remained motionless.

One day, two days, three days and four days...one week...

After a full week, the practice of Zhoubo Nine Yin Scriptures has not made any progress at all, and there is no possibility of reaching the next level. The strength has not improved at all at all, and there is no increase in its own strength at all.

The strength seems to have been completely limited here, and the feeling is quite subtle.

A practice takes only one week, and Zhou Bo does not look like he is out of seclusion.

Yun Ji and Zi Ye were both outside the wooden house, and that small wooden house was where Zhou Bo practiced.

In a week, no matter it was windy or rainy, Zhou Bo never appeared from it. He had been practicing in the wooden house and never appeared.

They didn't even drink a sip of water or a bite of food, and they never appeared. If they hadn't felt Zhou Bo's breath from the wooden house, Yun Ji and Zi Ye would even think that Zhou Bo was dead.

This was a very heartbreaking process. The two women were waiting outside. Even Qing Ming and Yanran often came out to visit, but Zhou Bo never showed up.

At this moment, Zhou Bo has reached the most critical moment. Just two days ago, Zhou Bo's Nine Yin Scriptures finally reached its full level.

With the full-level Zhou Bo's strength of the Nine Yin Scriptures, it has once again improved.

Zhou Bo can already come out of seclusion. As for the fusion of the Nine Yin and Nine Yang, you can try it after some preparation.

However, Zhou Bo was unwilling to give up such an opportunity. Without any rest at all, he immediately began to try to merge the Nine Yin and Nine Yangs together.

As a result, problems immediately arise.

The fusion of the Nine Yin and Nine Yang is different from the Eternal Life Skill. The Eternal Life Skill can automatically start to fusion after finding seven secret books. After all, the real difficulty of the Eternal Life Skill is in searching... No one knows where the Eternal Life Skill is hidden, and this is the most difficult thing.

If it weren't for Bai Xiaosheng's help, Zhou Bo wouldn't have known where this secret book was hidden.

However, the Nine Yin and Nine Yang are different. Everyone knows that the Nine Yin Sutra is hidden in Huang Laoxie, the old naughty boy, and Guo Jing. They all know that the Nine Yang Sutra is in Zhang Wuji's hands. Compared with this, it is undoubtedly easier to find these things.

Even if those opponents are stronger, they are still relatively easy in comparison. Compared to those things that have no clue and can only rely on luck to calculate, this is obviously many times easier.

Looking for secrets is not the real level of Nine Yin and Nine Yang. The real level of Nine Yin and Nine Yang lies in fusion.

Although the Nine Yin and Nine Yang are all authentic Xuanmen, they are quite powerful and upright forces. However, it is definitely not an easy task to completely integrate the Nine Yin and Nine Yang together.

They are all authentic Xuanmen, but the Nine Yin True Sutras tend to be yin, which can also be seen from the Nine Yin White Bone Claws. When they are used, they are full of ghost energy. However, the Nine Yang True Sutras tend to be yang and open and upright.

One sect has the most yang and the most yin and cold. It would be a torture to completely integrate these two sects.

Zhou Bo even felt that his body had almost become a battlefield. Whenever he controlled the powers of the Nine Yin and Nine Yang to merge with each other, the power of the Nine Yin and Nine Yang scriptures would have the most violent collisions in Zhou Bo's body. That feeling was like treating Zhou Bo's body as a battlefield. Flashes of terrifying fluctuations continued to appear in his body. The super-strong collision power almost completely tear Zhou Bo's body to pieces.

It is impossible to imagine how powerful that power is. The terrifying aura is constantly spreading and spreading, trying to completely tear Zhou Bo the whole person apart.

Yin and Yang do not merge.

The two forces, whose attributes are completely opposite, have become a difficult and unimaginable problem. Every contact between the two forces can cause violent collisions. Each collision is a burst of powerful force. That terrifying feeling is about to completely tear Zhou Bo.

Puchi...

Another attempt was made, Zhou Bo's body suddenly trembled violently, and then with a whistle, a mouthful of blood spurted out of his mouth, his face looked particularly shrill.

This time the fusion failed again.

hateful……

That kind of power made Zhou Bo unbearable and his body almost collapsed.

The power of the Nine Yin True Sutra and the Nine Yang True Sutra is too huge. Zhou Bo tried it many times, but failed again and again.

However, these failures seem to have brought Zhou Bo some experience, allowing Zhou Bo to find some solutions that can solve this failure.

suppress.

Both of these powers are powerful forces.

There is only one way to integrate these two forces, that is, to use the most powerful force and forcefully integrate these two forces together.
