In a flash, ten days passed.

During this period, Yang Xiao continued his crazy challenge every day.

Only this time, all he challenged was death-level. Every day is still a thunderous eighteen battles, and there is almost no time to rest in between.

At first, Luo Yan was still worried that if Yang Xiao continued to challenge like this, there would be no one in the Shura Hall of Canghai City who was willing to fight him. But later Luo Yan realized that he was too worried.

Those enthusiastic spectators are doing their best to spread the name of "Mu Yi".

As a result, Canghai City, which was originally at the bottom of the Tianxuan County Rankings and was unknown, suddenly became the focus of attention of some surrounding forces. Those strong men who heard of Mu Yi's name also came one after another, and instantly solved the problem that Yang Xiao had no opponent to fight.

And after these eleven days (including the day when the sword madman was subdued), although the realm has not been improved, Yang Xiao's combat effectiveness has undergone earth-shaking changes.

First of all, of course, is his physical body.

Although the realm has not improved, after experiencing a hundred-fold gravity pressure again and again, the strength of his immortal kun body has unconsciously made a qualitative leap.

At the same time, the purity of the true qi in his body was also stronger than that of ordinary people. This made the amount of True Qi he consumed to perform the same move much less.

The second is the comprehension of the origin of the potential.

Eleven days ago, he had just reached the entry level. And now, it has reached a small success.

This speed, even in the eyes of the Ancestor, is too demonic.

Of course, this is inseparable from Yang Xiao's crazy obsession and extraordinary understanding. Without these 188 trials of life and death, we would never have made such rapid progress.

And after the potential reaches the realm of Xiaocheng, the bonus to attack power has reached three times.

On the night of the eleventh day, Yang Xiao ended the last fierce battle and dragged his slightly tired body back to the room. Such a crazy challenge, even if he had a strong immortal body, he felt a little unbearable. And the elixir he seized from Tan Ji had long since been consumed.

"Now, I've won another 1,880 battle points. Go to the Treasure Pavilion again tomorrow and see if you can exchange one or two mid-grade martial arts!"

Yang Xiao stared at the order talisman and said secretly in his heart.

Although the realm of potential has been improved, in terms of martial arts, Yang Xiao has fallen into a bottleneck.

Whether it's "Explosive Fist" or "Seven Absolute Slashes", he can't take it any further.

For example, in "Bursting Battle Fist", in the past eleven days, Yang Xiao has always been attacking the "Ten Star Consecutive Break" that is above the nine-star consecutive break. But in the end, he couldn't make the trip, and he always felt that he was almost breathing, but he couldn't pierce the layer of window paper.

The same is true of "Flying Shadow Secret Art", the realm is still stuck at the beginning, and it is impossible to move towards Xiaocheng.

So at the moment, if you want to improve your strength, there are only two ways left.

First, nature is to improve the realm.

With the battle points he currently has at hand, it is enough to exchange resources in the Treasure Pavilion and impact to the eighth level of the Bloodline Realm.

However, this has the downside of increasing the difficulty of the hellish challenge.

After all, the realm of a hell-level opponent is selected according to the challenger's current realm.

If his realm is the seventh early stage of the bloodline realm, the opponent will be the tenth peak of the bloodline realm.

But if he reached the eighth level of the bloodline realm, then the opponent would likely appear as a half-step Yuan Sea Realm powerhouse.

The so-called half-step Yuan Sea Realm is an excessive realm.

Some strong people, in order to be able to go further and become stronger in the Yuanhai Realm, will often deliberately suppress the realm to lay a foundation. So this half-step Yuan Sea Realm appeared. Some martial cultivators who have been immersed in this realm for many years are not necessarily inferior in strength to the first powerhouse in the Yuanhai realm.

Yang Xiao is not afraid of challenges, but hell-level challenges, which are related to the starting point of his future in the Martial Saint Academy. He doesn't want to travel any way. Therefore, the path of ascending to the realm was ultimately denied by him.

Then the only way left is to cultivate higher-level martial arts.

After thinking about it, Yang Xiao communicated with his divine thoughts, and suddenly, the list of the Treasure Pavilion appeared in his mind again.

"Huh?"

After browsing for a while, Yang Xiao's eyes were condensed.

The previous time, due to the clear purpose and the advice of the ancestor, he quickly ran out of battle points. Therefore, he did not carefully browse the mid-grade martial arts of the prefecture level.

Looking at it at this moment, Yang Xiao found that almost the vast majority of prefecture-level mid-grade martial arts contain a unique potential, which is called "derivative potential".

Just as yin and yang are divided, yin and yang give birth to all things. As the most fundamental force between heaven and earth, "potential" also has many different derivatives, such as: the power of fire, the power of water, the power of wind, and so on.

Once these special derivative potentials are integrated into the martial arts, the power of the move will naturally increase exponentially. In addition, it will also make the trick have some unexpected effects.

For example, a set of "Wanchuan Sword Technique" contains the power of water.

Once cast, the move is like a rushing river, making the opponent feel as if he is in a torrent. In addition to the strong lethality, it also has great containment power.

Another example is a set of "Rock Avalanche Sword Technique", which contains the power of earth.

Once it is used, the trick is like a huge rock falling on the top of a mountain, and attacking and killing the enemy is like destroying the withering and decaying, and it is extremely domineering.

There are many more examples of the same.

It can be said that whether or not it has a potential has almost become a watershed between the low-grade martial arts of the prefecture-level and the middle-grade martial arts of the prefecture-level.

"It's no wonder that in Canghai City, the mid-grade martial arts of the prefecture level, except for the legendary Ouyang family, there is almost nowhere to be found. It seems that the main reason is here!" Yang Xiao suddenly realized.

After all, in a small place like Canghai City, no matter how top a martial artist is, it is rare for him to comprehend the "potential". Unable to comprehend the potential, these martial arts naturally cannot exert their power in their hands.

In fact, what Yang Xiao doesn't know at the moment is that the vast majority of geniuses who have comprehended the potential have actually taken a so-called shortcut.

That is, they started cultivating from those derived potentials, rather than first contemplating the originating potentials.

The advantage of doing this is naturally that at the beginning of cultivation, the progress is very fast. But at a certain point, bottlenecks will be encountered.

Because more high-level martial arts often have a variety of potentials. There are even some martial arts that require the fusion of potential.

There is often no correlation between different derivative potentials, which is somewhat similar to "interlaced like mountains".

Therefore, if you have been immersed in one derivative potential for a long time, to comprehend the second derivative potential will encounter obstacles like "crossing the line", not to mention comprehending multiple derivative potentials and integrating them.

Therefore, if you can comprehend a derivative potential at the age of 20 or so, you can be regarded as a genius; if you can comprehend two potentials at the same time, you can almost call it a demon; and if you can comprehend three potentials at the same time, that is, the great demon among the demons.

But Yang Xiao is not.

The experience he has obtained before is not any kind of derived potential, but the exposition of the origin potential can be described as the foundation of the foundation. It's like the "Tao" of "Tao gives birth to one, life to two". And after the guidance of the ancestor and his many days of tempering, he already has a deep understanding of the origin potential.

Therefore, the "cross-line" that is difficult to do in others is not a problem here in Yang Xiao. With a solid foundation, he can naturally grow luxuriant branches and leaves on it.

"I inherited the Kunpeng bloodline, and I have the bloodline divine ability of a free trip, and at the same time, I have a deep understanding of gravity in the gravity cultivation room before. Then this set of "Wanchuan Sword Technique" and this set of "Rock Avalanche Sword Technique" are the most suitable for me at the moment. The two books are combined, and a total of 1,800 battle points are needed, and I can just bear it!"

After thinking about it, Yang Xiao didn't delay any longer and went directly to the Treasure Pavilion.

Soon after communicating with the human puppet, two more clusters of light shot at the center of his eyebrows on the bookshelf. Ten breaths later, Yang Xiao's mind already had more information about these two sets of swordsmanship.

"Without further ado, cultivate as soon as possible!"

Yang Xiao thought about it and went straight to the gravity cultivation room.
