Although most of the foreign beasts sent by these powerful people and the major sects are foreign beasts under the fifth-level demonic energy, they are useless to Zhang Chenfeng's six-winged swallowtail snake, but because of the large number of strange beasts sent by these people, therefore, on the whole, there are really a lot of strange beasts above the fifth level, in total, there are hundreds of fifth-level demonic qi, there are thirteen kinds of sixth-level demonic qi, and even there is one seventh-level demonic qi.

Of course, eighth-level demonic energy, ninth-level demonic energy, that is definitely not there, not to mention ninth-level demonic energy, eighth-level demonic energy, just seventh-level demonic energy, then it is already heaven and earth demonic energy, not to mention ordinary magnates, martial arts and the like, it is just to change to a holy whirlwind period martial artist encountered, just afraid that if you smell it, you will also have to die, and when you reach that level, the beasts are not something they can pick at all.

Among these strange beasts, there can be a seventh-level demonic qi existence, or because that strange beast is a martial venerable, a strange beast found from an ancient secret realm and sealed with a special item.

Zhang Chenfeng has been busy absorbing these strange beasts for the rest of the time, except for the things in the past few days, and the six-winged swallowtail snake in Zhang Chenfeng's body has turned forty percent white, and it is only six percent away from the fifth evolution.

Of course, the six-winged swallowtail can evolve so much, except for Zhang Chenfeng who got a lot of strange beasts back from the Mainland Famous Doctors Association, mainly a few days ago, Wuyinglou sent a batch of strange beasts, otherwise, relying on these strange beasts sent by these guests, where can the six-winged swallowtail evolve to forty percent?

The fifth evolution of the six-winged swallowtail snake, although it has completed forty percent, and the strange mist produced is also a lot, but Zhang Chenfeng has not advanced during this time.

Because it won't be long before someone will come to treat the disease in the Shadow Building, and in addition to the Shadow Building, someone will come to treat the disease, and the owner of the Blood Demon Mansion will also send someone to treat the disease.

And once Zhang Chenfeng is promoted, with his current state, he can at least be promoted to five spins in the rotation period, or even more than six spins.

It's only been two or three months, and it's scary enough to be promoted from one spin to three spins during the rotation period, and it would be strange if it was also promoted to five, six, or even higher, without arousing the suspicion of those people.

Zhang Chenfeng didn't want to be targeted by the people of the Shadowless Building and the Bloody Mansion because of his fast promotion.

Whether it is the Shadowless Building or the Bloody Building, for the current Zhang Chenfeng, it is a behemoth-like existence.

Zhang Chenfeng can't afford to provoke anyone!

So in order not to suspect together, Zhang Chenfeng has always restrained himself from advancing and maintained his current rank.

Zhang Chenfeng returned to his room, and as usual, he selected a few kinds of alien beasts that the six-winged swallowtail had not yet absorbed, and after absorbing them, he began to sit cross-legged on the bed and began to cultivate the "Xuanshen Heart Sutra".

For Zhang Chenfeng, the "Xuanshen Heart Sutra" must not be delayed, the effect of the "Xuanshen Heart Sutra" is too big for Zhang Chenfeng, with this "Xuanshen Heart Sutra", you can do things that you didn't even dare to think about on the earth before.

The cultivation difficulty of the "Xuanshen Heart Sutra" is very high, Zhang Chenfeng has practiced for more than half a month, and he has not broken through to the first level, and he is still so close to the door.

Zhang Chenfeng is preparing to break through the first weight tonight.

Zhang Chenfeng, who was sitting cross-legged on the bed, closed his eyes slightly, and then began to stimulate the nerves in his brain with martial arts according to the "Xuanshen Heart Sutra".

The first three parts of the "Xuanshen Heart Sutra" need to stimulate the hidden meridians of the brain, that is, the nerves of the brain, so that they can breathe martial arts.

The first is that it is necessary to stimulate the thirty-six brain nerves, and to operate the first martial arts, it is only considered to be able to fully operate one of the thirty-six nerves, and Zhang Chenfeng is still short of the last brain nerve at the moment.

Zhang Chenfeng, an earthling, who has also studied neurology, has an understanding of brain nerves that is not comparable to the martial artists of the Shenwu Continent at all.

Don't look at Zhang Chenfeng's cultivation of the "Xuanshen Heart Sutra" for more than ten days, he has not yet started, but he is only the last step, and at this moment, among the Heavenly Sword Sect, the martial artists who have begun to cultivate the first level of the "Xuanshen Heart Sutra", including Jian Wushuang, the holy whirlwind martial artist, the most powerful is only to open up the six brain nerves, which is far worse than Zhang Chenfeng.

Zhang Chenfeng controlled the subtle martial arts, slowly extending to the last brain nerve that needed to be opened, and then slowly stimulated with the martial arts.

The nerves in the brain, no matter which one they are, are extremely important, some may affect people's movements, some may control people's pain, and some may even control people's thinking, once there is a problem, the consequences are extremely serious.

Therefore, when practicing the "Xuanshen Heart Sutra", Rao is Zhang Chenfeng knows the nerves of the brain very well, and he does not dare to be careless, for fear that if he is not careful, he will bring serious trauma to his body.

This is also the fourth time that the six-winged swallowtail has evolved, if the six-winged swallowtail has evolved into the king of the six-winged beasts, then Zhang Chenfeng does not need to be so careful.

Once the six-winged swallowtail snake evolved into the king of the six-winged beasts, Zhang Chenfeng's brain was no longer a forbidden area for the natal beasts, and he could move freely throughout his body.

The six-winged swallowtail can secrete a special liquid to repair the meridians, and the brain nerve is also a kind of meridian, but it is a special meridian, and the special secretion of the six-winged swallowtail can also be repaired, so if you practice the "Xuanshen Heart Sutra", you don't have to worry about brain nerve trauma, and you can directly stimulate it generously, which is much simpler and easier.

Finally, the brain nerves that need to be stimulated add up to only about two centimeters, but for this brain nerve, Zhang Chenfeng has spent nearly three days.

Because this brain nerve that needs to be opened is extremely small, not to mention, hidden in the memory layer of the brain, it is a memory nerve, once there is an accident and this memory nerve is injured, then it is likely to cause amnesia.

Therefore, Zhang Chenfeng was very careful, and when he stimulated this brain nerve, the martial arts controlled were extremely weak and extremely careful, so it took three days for such a long meridian to be completely opened.

Zhang Chenfeng controlled Wu Xi to slowly probe towards the end of this brain nerve, and controlled Wu Xi to slowly stimulate the brain nerve at the end that had not yet been opened.

An hour...... Two hours...... Four hours......

In the blink of an eye, four hours have passed, and this meridian is still a little bit away, and it only needs to be stimulated again at the end, and this brain nerve can be completely opened up and enter the first weight of the "Xuanshen Heart Sutra".

I don't know, how much mental power can be increased by this first weight, I'm really looking forward to it!

While looking forward to it in his heart, Zhang Chenfeng controlled Wu Xi and probed towards the nerve in his brain again.

Boom! Boom!

A roar sounded in Zhang Chenfeng's mind, the last meridian was opened, and Zhang Chenfeng entered the first weight of the "Xuanshen Heart Sutra".

As Zhang Chenfeng entered the first level of the "Xuanshen Heart Sutra", Zhang Chenfeng could clearly feel that his perception had become stronger, and everything within a hundred and ten meters around him seemed to be completely under his control, which was the reason why his spiritual power had increased significantly.

Feeling all this, Zhang Chenfeng's face was full of joy, and he was extremely excited in his heart:

This "Xuanshen Heart Sutra" can increase the strength of the spiritual power and soul exercises, which is already against the sky.

I didn't expect this "Xuanshen Heart Sutra" to go against the sky to such a point.

Mental power is released!
