The Qi source in the dantian occupied a little more than nine-tenths of the Qi Pond, and Xu Yang did not continue to eat Qi Guo to break through.

There must be a little room for Qi Yuan to rise, after all, it is in the process of absorbing spiritual energy cultivation all the time, although the speed is not fast, and the increase in Qi Yuan is very small, but if you don't leave a little space, it will soon be filled.

These days, when the treasure chest is opened, there have been no new items, let alone the big treasure chest, even if you can't even see the middle treasure chest.

Xu Yang is also very helpless about this, this is a broken game, and he doesn't know what to do.

Perhaps, you need to wait until you upgrade to Samsung before you have a chance to open a big treasure chest?

Controlling the game villain, he began to jump the grid, and the familiar convenience store grid, as well as the small tree grid of Qi Guo, appeared one after another.

An hour later, Xu Yang was about to stop playing.

Since I can't rush to break through recently, I can't open up new things in the mini game, and I have accumulated a lot of beef jerky and Qi fruit.

It's better to accumulate anger points, and after leveling up, you can open more Qi fruits, and in a very short period of time, you can improve your strength.

Even, the anger value has accumulated a lot, and maybe there is a better chance of opening a big treasure chest.

Xu Yang decided that after playing this one, he would not continue to play, and if he could save 10 million anger points, then he could definitely open a big treasure chest, right?

Ten million is a bit difficult, but with two million rage points, it shouldn't be a big problem.

At present, the rage value is maintained at eight or nine hundred thousand, and occasionally it breaks through to one million, and just playing a small game, it will consume some rage and drop from millions.

Manipulating the villain to jump onto the convenience store lattice, and then jumped on the lattice of a small tree with a fruit tree, and continued to jump forward.

Suddenly, a mailbox grid appeared.

Xu Yang was overjoyed in his heart, another exercise was about to be opened?

Successfully jumped onto the mailbox slot, and a treasure chest popped out.

Finally, another treasure chest was opened, and it should be of the exercise class.

But I don't know what kind of exercises it is.

Xu Yang couldn't wait to open the treasure chest.

The flowers are shining and very festive.

On the screen of the mobile phone, a black picture of a book appears, and below it is a line of introduction:

"The Derivative Poison Sutra can derive toxins, and all kinds of poisons and various heterogeneous poisons can be derived from ......"

Xu Yang was ecstatic in his heart, it turned out to be an exercise related to his poison ability, and he was finally able to fully master the poison ability, without worrying about what the toxin would become.

Retrieved the Poison Sutra.

A black light penetrated into his head.

In my mind, it was as if a black book appeared, slowly opening the first page.

Xu Yang couldn't wait to check the content inside, which was introduced, how to derive toxins, and how to use poisons.

The Poison Sutra is a poison scripture, a very powerful poison scripture, all poisons are recorded in it, and including the solution to each poison, etc., which records all kinds of strange poisons.

It's just that Xu Yang can't read the entire Poison Sutra completely, and he can only see the first third of the text, and the content behind him can't be seen, maybe the poison system is not strong enough, so he can't view it?

Xu Yang regretted it in his heart, but he was not annoyed, only the first third of the content, the various toxins recorded, and the method of using poison, were enough for him to study for a long time.

According to the above records in the Poison Sutra, poison can be derived according to the will, for example, if you want the enemy to do broadcast gymnastics, then you can use this as an idea to derive a toxin and use it on the other party, which can make the other party can't help but do broadcast gymnastics.

However, it is very difficult to derive this specific toxin.

And the simplest, poisoning toxins, and the dizzying general, single and non-specific toxins, are relatively simple to derive, the key is the strength of the toxin.

The Poison Sutra can be said to be a poison scripture tailored for Xu Yang, all poisons can be derived from the Qi source in the body, and there is no need to look for poisonous materials and how to mix them.

Similarly, the antidote can also be derived from the source of Qi.

It can be said that as long as Xu Yang masters the Poison Sutra, he is not only a master of poison, but also a master of detoxification, I am afraid that there is no poison in the world that he can't solve.

The premise is that when faced with some particularly terrifying toxins, he has enough Qi source to be able to derive an antidote.

Xu Yang is obsessed with the Poison Derivation Sutra and studies it every day, not only learning and comprehending the method of poison derivation, but also the method of using toxins.

It is not so easy to derive toxins, especially to locate them.

This is also the reason why the toxins that Xu Yang derived before will be crooked, mainly because the toxins that are derived deviate from his assumptions.

After three days of research, Xu Yang finally derived a toxin that would not be crooked.

Three-step soft!

It is not a deadly toxin, but a toxin that can make people feel soft and soft, similar to a sad crisp breeze.

"Three-step softness, effective for two-star cultivators and below, after poisoning, the whole body is weak and weak, unable to use the ability, three-star cultivators are half-soft after poisoning, weakening half of their strength......"

Xu Yang is still quite satisfied with the three-step softness, but since it is poisonous, of course it can be prevented, and it is not possible to ensure 100% that the enemy is poisoned.

Anyway, with poison, most of them don't follow the path of fairness.

With Xu Yang's current two-star strength, the three-step softness derived from it can weaken half of the strength of a three-star cultivator, and when he is promoted to a three-star level, he can weaken half of the strength of a four-star cultivator.

Skipping battles, there is no pressure at all, not to mention the toxin, it also has the ability to skip the fight, but after using the toxin, there is no problem with one or two.

Of course, the premise is to be able to poison the other party.

This is to study how to use toxins, how to make toxins pervasive, how to invade the practitioner's defenses and poison the other party.

Xu Yang felt that he still had a long way to go on the road of poison.

After deriving a three-step soft toxin, Xu Yang decided to test the power of the toxin, and the first thing that came to mind was naturally Lin Haifeng's two snakes.

Those two snakes are very poisonous, much stronger than two-star cultivators, even if they are not as good as three-star cultivators, it is estimated that they are not much worse.

In addition, you can also test the new poison that is derived, and after the two snakes are poisoned, will they produce new skills.

Lin Haifeng kept his snake all the time, and found that there was no problem for a few days, it returned to normal, full of vitality, fast speed, strong combat effectiveness, and it was not far from the second star.

If the spirit snake pet wants to advance quickly, it can't do without the cultivation of spiritual objects, of course, with the current storage of spiritual objects in Skynet, it is impossible to have excess to cultivate spiritual snakes for him.

There are no spiritual objects, and spirit stones are also important resources, so Lin Haifeng obtained two more spirit stones than other students, and the extra two pieces were used by him to cultivate spirit snakes.
