gene era

However, in Xu Tui's place, there is no problem at all.

Lu Kang was stunned, and then gave Xu Tui a suggestion, "You can enjoy the rewards of the Tianjiao team's overall list all by yourself.

For these two special rewards, my suggestion is that you choose to customize a combat uniform, and at the same time choose the casting opportunity of the genetic weapon casting master once. "

"No, I chose the casting opportunity of the genetic weapon casting master both times." Xu Tui said.

"It is also possible to choose this way.

But you have to know that the genetic weapon casting master is only responsible for making shots, and you need to prepare and exchange the materials yourself.

If the materials are not good, precious opportunities will only be wasted.

You have to consider..."

Halfway through speaking, Lu Kang was stunned.

Xu Tui received 18 meritorious service this time, which is enough to exchange for better materials.

This is really a trench!

To be honest, the personal merits on his account are not allowed to be refunded so much, not even one-tenth.

I can't save it!

"you sure?

If you are sure, I will report it, and then help you contact the casting master to see who has the time to help you cast your exclusive genetic weapon. "

"Sure!" Xu Tui gave an affirmative answer.

"Well, I will report according to this choice. There may be an arrangement within a few days. You'd better discuss with your teacher in advance which direction of genetic ability to choose to forge genetic weapon enhancements.

It is best to have preliminary designs and ideas.

Even related materials, also understand.

Price and features, as well as cost performance, so as to make the best choice and configuration. "Lu Kang said.

"Understood! Thank you instructor."

Led by the instructor Lu Kang, Xu Tui received a huge reward, which can be called a green light all the way.

Got them all quickly.

The only problem is that the source energy strengthens the targeted mutation potion.

The value of this potion is huge. Those with personal authority below B level can exchange up to [-] merit points for a bottle, and those with personal authority above level B can exchange for [-] merit points for a bottle, and there is still a limit on the number.

Circulation is extremely limited.

On the extraterrestrial black market, someone bought [-] grams of source crystal at a high price.

Under normal circumstances, one gram of source crystal is worth one thousand merit points!

In order to prevent reselling and strict storage conditions, this energy-enhancing directional mutation potion must be used on-site after receiving it.

And the interval between using the source energy-enhanced directional mutation potion is at least one day.

Xu Tui's battle merit ranking rewards earned Xu Tui a total of five bottles of directional enhancement mutation potions.

Originally, which genetic ability chain to mutate had to be carefully selected.

However, Xu Tui now has five bottles of source energy strengthening directional mutation potion, and he can exchange a few bottles for later, so he doesn't need to be too cautious.

Use it first.

After all, even if you use one bottle a day, it will take five days at the fastest.

After thanking the instructor Lu Kang again, Xu Tui directly took a bottle of source energy strengthening directional mutation medicine and injected it on the spot.

It seems that the instructor Lu Kang is not sullen!

When he was still in the genetic mutation environment, he was lucky enough to get a bottle of source energy strengthening directional mutation potion, how to use it.

At the beginning, it took three days of continuous discussion with his teacher before making a decision.

It's better to retreat.

Use it on the spot!

Chapter 428 The source energy that does not listen to greetings

In fact, it didn't take five days to use up five bottles of energy-enhanced directional mutation potion.

When there are and only one or two bottles, every time you choose one, be extremely cautious!

Just like marrying a daughter-in-law or finding a husband, you only have one chance, and you will combine factors such as height, figure, education, income, personality, family, hobbies and even collect the genetic information of the other party to make an extremely comprehensive comparison. Selection!

But Xu Tui now has five chances.

And more than five times, Xu Tui's personal meritorious service has the opportunity to exchange it.

Therefore, the chances of Xu Tui marrying a wife may be five or six times, or even seven or eight times.

This is just a metaphor.

In this case, it was very easy for Xu Tui to choose which ability to use the source energy strengthening directional mutation potion on.

If you are in good shape, you can cook, you can hammer your legs, you can wash clothes, you can warm your quilt, you can get one of all kinds.

If you find that a certain direction is missing, come up with another one or two.

Therefore, it took Xu Tui two and a half days to use up five bottles of source energy strengthening directional mutation potion.

It directly made Lu Kang, the instructor who accompanied him, a little nervous.

At the beginning, he discussed with the teacher for three days before finally deciding how to use the bottle of directional enhancement mutation potion.

On Xu Tui's side, it was used up in one afternoon and one morning.

As for Xu Tui's harvest, instructor Lu Kang couldn't see it.

Not particularly excited, not particularly depressed.

This is also normal, after all, this is not the first time Xu Tui has injected.

Before, two bottles have been injected.

Harvest, for sure.

Xu Tui just thought about the five bottles of directional strengthening mutation potion and made an arrangement.

The only tangled gene ability chain is the mental power chain.

Do you want to try to strengthen and mutate it?

When Xu Tui's combat radius was only tens of meters or 100 meters before, this mental power chain was very powerful.

It can double the distance of Xu Tui's flying sword.

But now, Xu Tui's combat distance has far exceeded 1000 meters.

The ability of the mental power chain suddenly became a bit tasteless.

Xu Tui had been thinking about it, would it be a waste to use a source energy directional strengthening mutation potion for it?

Because of this, Xu Tui used the first four bottles of source energy directional strengthening mutant potions in the four genetic ability chains of water puppet, diamond mask, spiritual resonance, and neural response speed.

It can be said that it is bad luck or a matter of probability to use four bottles of energy-directed strengthening mutation potion in a row.

After all, after the source energy is directed to strengthen the mutation potion, the ability will be strengthened to a certain extent, which is 20.00%, but the mutation rate is only [-]%.

The two bottles of energy-enhanced directional mutation potions used before were full of luck, and the mental power whipped directly to the mutation.

Although the telepathy was not as successful as the mutation, but there was fusion first, and then penetrating induction, which was almost the same as the mutation.

However, these four bottles of source energy directional strengthening mutation potion only mutated once.

What has changed is the ability of spiritual resonance.

The genetic ability chain of spiritual resonance has already been strengthened to level two silver by Xu Tui.

Therefore, after injecting the source energy to strengthen the directional mutant medicine, the improvement in its ability is actually not that great.

However, the main genetic point of spiritual resonance has a pattern.

There are patterns, which represent the alienation of ability.

The pattern of the main gene base point of spiritual resonance, a circle of ripple-like patterns, at first glance, looks like rippling water waves, but at another glance, it looks like electric waves passing through layers.

Especially the direction of ripple conduction, it seems that it can be inside or outside.

This gave Xu Tui some guesses, but if he wanted to test the ability of spiritual resonance, he had to find the right person.

Xu Tuijue, Teacher An Xiaoxue'an is the best choice.

Rough guys like Lu Kang and Yan Lie were directly excluded by Xu Tui.

I'm free to resonate with you, a big man?

Except for spiritual resonance, the other three abilities have no changes.

But there is no mutation, but it does not mean that the ability is not strengthened.

Otherwise, the source energy strengthening directional mutation potion would not become one of the most valuable potions outside the earth.

Especially those quasi-planetary-level or even planetary-level powerhouses will definitely exchange a few bottles of source energy strengthening directional mutation potions for their descendants.

Xu Tui's first ability to strengthen the mutation was the ability of the water puppet.

The water puppet's ability is not commonly used, but it can support Xu Tui at critical moments every time. It is resistant to beatings and hammers, and has a strong binding force. It is extremely convenient to use.

Even if there is no water, a spout of saliva will probably do it.

Unfortunately, there is no mutation.

Power slightly increased.

In this regard, Xu Tui suffered a little.

After all, almost [-]% of the genetic mutation environment and the genetic ability chain are first-level, and there is not even a second-level genetic basis.

But Xu Tui's genetic ability chain, not only all the genetic bases are at the second level, but even the genetic ability chain is at the second level as a whole.

If another ordinary student came here and injected a bottle of source energy directional strengthening mutation potion, he would definitely be able to strengthen three or four second-level gene base points, and his ability would be greatly improved.

But Xu Tui's improvement is very limited.

In the previous test, the energy requirement for upgrading from the second-level gene base point to the third-level gene base point is about [-] to [-] times that of upgrading from the first-level gene point to the second-level!

In this case, the improvement is limited.

Of course, it is also a kind of accumulation.

Xu Tui manifested a water puppet on the spot and asked the instructor Lu Kang to help test it, but he didn't find much improvement.

It was the instructor Lu Kang who used two punches to smash Xu Tui, the water puppet!

The vajra cover is the same as the water puppet, it has no mutation, but it has been slightly strengthened.

The same is true for the neural response speed, there is no mutation, although the genetic base point has also been strengthened, but the improvement is negligible when it is fed back to the ability.

Compared with the improvement of strengthening the entire genetic ability chain to the second level, the improvement of the source energy strengthening directional mutation agent this time is too small.

After all, on the battlefield of Mars, at that time, the source energy entered the body and was promoted, like a flood.

Without the mutation, the current increase is naturally very small.

Xu Tui thought a little about which gene ability chain the fifth bottle of source energy strengthening directional mutation potion should be used on.

The previous idea was that since the ability of spiritual resonance has undergone a mutation, will the other genetic ability chains of the radiation influence system be more likely to undergo mutation after using the source energy to strengthen the directional mutation potion?

The probability of a mutation in the genetic ability chain, apart from the probability of the medicine itself, is affected by many factors.

For example, a gene in a human body, a hidden recessive gene or a silent gene.

Mutations are likely to be the reactivation of certain recessive genes or silent genes.

However, the recessive genes or silent genes carried by each person are different.

Moreover, according to the bold inferences of some professors, certain genes may naturally have more mutation possibilities.

Therefore, when Xu Tui used the fifth bottle of source energy to strengthen the directional mutation potion, he considered a problem, probability and demand!

Probability!
