If the Y element is only able to react with the X element to create zombies, anomalous beings, and mutated creatures, then its role is mainly for scientific research, and it is not of much use in practical applications. Pen "Fun" Pavilion www.biquge.info

However, the Y element is indispensable for the evolution of the Advanced Abilities.

To evolve from a B-class to an A-class, and from an A-class to an S-class, in addition to absorbing enough X, you also need the Y element to complete the final step of evolution.

It's the equivalent of scoring a goal in football. The goalkeeper served, and after a series of passes and cooperation from the defender, midfielder, forward and forward, the football finally came to the perfect position in the opponent's penalty area, and there was only one last step left to score.

The striker's last kick is the final step in scoring a goal, and the Y element plays such a role in the evolution of the advanced ability, which must be transformed into a qualitative change by the Y element after a Ability's X element has absorbed enough of it, so that the ability can be successfully upgraded.

There's another problem here that is prevalent in the X era, and that's probability.

People are infected into zombies, people awaken into aliens, creatures mutate into mutated creatures, zombies mutate into mutated zombies, these all have a problem of probability, and the same is true for the evolution of high-level aliens.

It's not that a striker will be able to score a goal with a shot in the first shot, the shot is likely to be saved by the goalkeeper, or it may be a direct hit.

The evolution of high-level abilities is also like this, it does not mean that the content of element X reaches the standard, and if you encounter element Y, you will definitely be able to evolve successfully. There's also a question of probability.

According to statistics, this probability is about 50%, and on average, it takes two New Year's Days for a high-level ability to successfully evolve, that is, two years.

Su Jiangchen's luck in his previous life was generally not bad, he became an A-level ability in the 5th year of the X era, and an S-class ability in the 7th year of the X era, but he failed once on New Year's Day in the 4th year of the X era, although he was not the first to reach the S-level ability, but he was also among the earliest ones.

And Liu Yunmo in this life is very lucky, he who has reached the X element content standard, and he was lucky to become an A-level ability on New Year's Day in the 2nd year of the X era.

Considering that it is very difficult to absorb enough X-elements to evolve into A-class abilities in one year, and this probability problem, the number of A-class abilities in the second year of the X era is definitely very small.

In the previous life, human beings would eventually lose to zombies and fall to extinction, one of the most important reasons is that on New Year's Day of the 10th year of the X era and later, the Y element never patronized the earth again, and the later superpowers could not evolve to A-level and S-level, and the old high-level superpowers would be sacrificed, and fresh blood could not be replenished, and human beings were eventually "grinded to death" by higher-level zombies.

In this life, Su Jiangchen suddenly discovered that the mysterious substance in his body could store the Y element, he was not a scientific researcher, and he did not know how much Y element he stored, but this was still an extremely exciting and even crazy discovery.

After the absorption of X element in his body reaches double the standard of A-class ability, releasing some Y element from the mysterious substance may allow him to evolve into an A-class ability, and can also allow other companions to evolve into A-class ability, or even S-class ability, which can undoubtedly reduce the dependence on New Year's Day, and the ability evolution is more flexible and has more opportunities, making the strength of the City of Light far superior to other forces.

Su Jiangchen once imagined that the war with the zombies in this world must end before the 10th year of the X era, and it seems that with the mysterious substance in his body, this time to end the end of the world does not necessarily become a condition for limiting his death.

Moreover, if the stored Y element is given to Duan Xue or even Dr. Ye for research, more great results may be achieved that are difficult to predict!

At this moment, Su Jiangchen's mood became very happy, not only because his plan was implemented smoothly, but more importantly, the new use of the mysterious substance was likely to change the world!

He firmly believes that this is an important milestone on his path to reversal!

......

Everything has advantages and disadvantages, when the mysterious substance is used to store the Y element, the Y element in it has already become Su Jiangchen's heart and baby bump, he has no time to test whether the other uses of the mysterious substance can be used normally, but he does not dare to take such a risk, otherwise, the next opportunity will be until the New Year's Day of the 3rd year of the X era.

Therefore, in the face of blindness that can be easily resolved into invisible, Su Jiangchen's choice is: blindness is blindness, invisible, I should have no problem dealing with you miscellaneous fish.

Su Jiangchen, who did not use a mysterious substance, really became a blind man for the time being.

In fact, for a master with rich combat experience like Su Jiangchen, listening to the wind and even by feeling can perceive the enemy's movements, but suddenly unable to see things, his adaptation needs to be processed.

In this process, he felt very twisted, very unaccustomed, ten percent of his strength could only play fifty out of five, and he immediately fell into a disadvantage under the siege of 7 abilities.

These 7 people obviously had already formulated reasonable tactics and made sufficient preparations, and after seeing Su Jiangchen being blinded and falling into a disadvantage, they did not rush to achieve success, but fought steadily, striving to gradually expand their advantages and grind Su Jiangchen to death and kill him.

The only advantage that Su Jiangchen had was that he already knew what all the abilities of these 7 people were, and he was mentally prepared in advance, because when they came to his side, he shook hands with these people in a friendly manner!

After blinding, it's the turn of the grid to release!

This tactic must have been carefully arranged, first restricting Su Jiangchen's senses, and then restricting Su Jiangchen's actions.

Su Jiangchen, who was not used to seeing things, reacted half a beat slower, and was covered by the power grid that was made and released on his head, and immediately his body was like being irradiated by X-rays, and at the moment when the current was at its highest, it seemed that his bones could be seen by others.

The current disappeared in an instant, this ability was only a C-level ability after all, with Su Jiangchen's B-class ability's body, even if he didn't use the mysterious substance, it would not be a problem to carry it hard.

But the current dissipated, and the net was still covering Su Jiangchen's body.

I didn't expect that the power grid created by the power grid with the ability to really form a substantial network.

Su Jiangchen's physical mobility was immediately greatly restricted.

At this time, those main attackers took advantage of the situation to attack.
