"Really?"

Zhang Xin's eyes were slightly joyful. He was convinced of Ye Ruo's words. The latter has proven her abilities countless times.

And if you are not sure enough, Ruo'er never makes promises easily.

If Ye Ruo can really succeed, it will greatly reduce his burden.

The current Water Moon Gu is able to store about one hundred and twenty points of spiritual energy. After completing the evolution, it is about 480 points.

In other words, at that time, he only needed the number of a thousand, and he could have nearly 480,000 spiritual energy points. If you have 5,000, you can have 2,400,000 points.

——These five thousand should be the maximum number he can control in his current cultivation battle realm.

In addition, this thing can also speed up his psionic energy recovery.

With only about 5,000 pieces, these little things can continuously supply him with more than 5,000 points of spiritual energy per second.

This doesn't seem like much, but even if he doesn't stop casting the Instant Shadow Thunder Body now, it is only a loss of three thousand points of spiritual energy per second.

However, this mutated Water Moon Gu, although the prospect is gratifying. But it can really be cultivated, but it is extremely troublesome.

Don't look at the thickness of this thing, it's less than one percent of a hair. But its genetic chain is extremely complex, almost not inferior to humans. In addition, Zhang Xin also had to adjust their psionic structure.

So for a short time, this thing can't be counted on for the time being. Zhang Xin could only spare some free time every day to cultivate these Gu worms.

It is mainly warmed with spiritual energy, which promotes its egg-laying, and then with the help of Ye Ruo, adjusts the genes carried by the eggs.

And this genetic adjustment is not done all at once. Ye Ruo divides it into six stages, and after each adult lays eggs, it will be slightly fine-tuned to avoid too many steps that would lead to genetic collapse.

But it takes at least twenty days for the Water Moon Gu to go from larvae, to adult, to egg-laying. This also meant that it would take him more than four months just to help these Water Moon Gu complete their evolution.

In addition, Zhang Xin also found that the fertility rate of these mutated 'Lingyue Gu' was extremely low.

The unmutated version is often a big lump for life. In the mutated case, the female can only lay five to six eggs at a time.

Sure enough, as Ye Ruo said, the more powerful the creature, the lower the fertility rate.

Therefore, although the human beings of the Earth Federation have a lifespan of up to 2,000 years, the population growth rate in the past 10,000 years is less than 42 percent, which is outrageously low.

And the Diracron located in the eye of the North Sea, which has not yet had a surviving descendant.

Fortunately, Zhang Xin has now completed the seventh battle realm and has the ability to multitask. Although cultivating the 'Spirit Moon Gu' was very complicated and required careful operation, and there could be no mistakes, it actually did not affect his cultivation.

Especially Zhang Xin, after completely digesting his feelings in Dayushan.

During this time, he was actually adapting to refining the various injections that Ye Ruo injected him. And his brain, except for turning a little every day to pay attention to the situation in the North Sea, most of the rest of the time, is not needed.

Speaking of injections, it is necessary to mention Zhang Xin again, the harvest when he was in Dayushan,

Many spirit masters in the world like to find strong enemies as opponents to sharpen themselves and improve their combat realm and cultivation. This kind of practice seems nonsense, but it is actually very reasonable.

In this battle of the Great Imperial Mountain, Zhang Xin benefited a lot under the oppression and stimulation of the gods. In this short battle, his 'meat chakra', which had only been developed for less than a day, had unleashed nearly sixty percent of his potential, which was equivalent to four months of his cultivation.

However, the biggest improvement is still the battlefield attainment. His entry in this area can be described as a thousand miles in an instant. It's just that in less than half a moment, his battle realm has crossed to the later stage of the 'Three Flowers Gathering Peak'. With a little more effort later, you can try to reach the next level.

And the biggest benefit of this battle realm after upgrading is to break his physique and the upper limit of the primordial spirit.

In short, he is now able to use all kinds of drugs and elixirs unscrupulously. In terms of medicine, Ye Ruo is well prepared.

Previously, Zhang Xin had unearthed twenty-two injections in the Divine Stone Fortress that he had never used, and the medicinal effects were different, but they were all extremely beneficial.

During this time, in addition to completing the pharmacological tests of all the injections, Ye Ruo restored seven kinds of formulas of those medicines.

In addition, according to the ingredients of these injections, as well as the various elixirs that Zhang Xin gave her to analyze, she also made four more series, with a total of nineteen types of injections.

Zhang Xin naturally didn't dare to inject these drugs into his body in one go. This is both dangerous and extremely wasteful. He just took seven of them at Ye Ruo's suggestion.

So a month later, Zhang Xin's 'Taiqing Immortal Body' had already reached the fifth level of perfection, the 'Tianyuan Dafa' had also reached the fifteen-fold realm, and the 'Dutian Shuangyuan Method' of the gold system pointed directly to the ninth layer.

And the biggest improvement is the physique, in addition to the eight points of physique brought by the 'Taiqing Immortal Body'. With the development of his meat chakra potential, as well as the help of drugs, he gained another eight physiques.

This made Zhang Xin's physique strength climb to one hundred and ninety-nine points, which was closer and closer to the threshold of the qualitative change in his physical body at the two hundred and twenty points that Ye Ruo said.

However, at this time, Zhang Xin is also thinking about his next step.

At this time, all of his mid-level exercises were close to perfection. But he still hadn't thought clearly about what kind of high-level martial arts he should practice.

In the past, he only cared about improving himself quickly and gaining the power to protect himself. He hadn't thought much about how he would go after he was in the Divine Master Realm.

The path he had traveled in his previous life, he had come to an end. He didn't know what to do next.

Therefore, after he cultivated the 'Tian Yuan Dafa' to the fifteenth level of perfection, he was no longer in a hurry to improve. Instead, he set aside some time every day to read through the books of the Seal Star Building.

With his current status and meritorious deeds, he is already qualified to observe any secret tome on the ninth floor of the Seal Star Tower. But in fact, at this point, even with the accumulation of tens of thousands of years of Sun and Moon Xuanzong, he couldn't improve too many choices for him.

In the ninth floor of the Seal Star Tower, there are only seven high-level thunder systems without a superior level, there are only thirteen high-level gold systems without a superior level, of which twelve are exercises such as the imperial sword and needle, and there are only six wind systems without a superior. As for the power of Tian Yuan, there is no one.

During this time, Zhang Xin was comparing the advantages and disadvantages of these exercises, and was always paying attention to the black market.

If there is a suitable exercise in the Seal Star Tower, it is naturally better to exchange it in the door. But if it's really not suitable, he won't stick to the existing methods in the door.

Two of the exercises that Zhang Xin practiced before originated from outside Xuanzong, and there was no inheritance within Xuanzong.

And after a five-day selection, Zhang Xin finally chose a high-level exercise called 'Liangyi Heavenly Breaking Law and Thunder Jue'.

As the name suggests, the person who created this technique in the first place was to 'break through all the laws in the world'.

Practicing this technique can further strengthen the power and forbidden range of his 'Thunder Heavenly Divine Silence', 'Thunder God's Hammer', 'Thunder Vein Divine Forbidden', 'Thunder Vein Absolute Prison' and other techniques.

After the Six Heavens, you can also cultivate a technique called 'Dutian Breaking Law Divine Thunder', which is not only powerful, comparable to Feng Yuan Po, but also can destroy all invisible techniques in the world.

And once the twelve heavens are consummated, the cultivation reaches the realm of great perfection. This 'Du Tian Po Fa Divine Thunder' can be derived from the 'Du Tian Po Fa Thunder Domain', which itself can also be used to destroy the opponent's law domain, and has the ability to destroy other people's primordial gods.

At that time, his opponent, even if he only stood within the 3,000 zhang range of the 'Dutian Breaking Law Thunder' or the 'Dutian Breaking Law Thunder Domain', would damage the Yuan Shen.

Even those god-level powerhouses are no exception, but the severity of the injuries is different. And if it is hit head-on, then even if it is as strong as a god, I am afraid that it will not be able to withstand the blow of the 'Dutian Breaking Law Divine Thunder'.

However, this 'Liangyi Heaven Breaking Law Thunder Technique' was obtained by a divine domain ancestor of their Sun Moon Xuanzong 40,000 years ago, and the source is unknown, and the highest record of practicing this method in the sect is only the eighth heaven.

In other words, this Dafa seems to be perfect, but in fact, it may not be able to be practiced perfectly.

Zhang Xin didn't care much about this, what he valued was the ability and prospect of this exercise, and if there were really any shortcomings, he could also improve it.

After that, in the gold system, he selected four supreme-level high-level sword techniques, three secret-level high-level sword techniques, and the only non-superior high-level gold system technique "Taihao Golden Tribulation".

However, he is not going to practice these, but he just plans to take some time to study and understand these exercises thoroughly for reference. Use them as their own resources to perfect the 'God Slaying Tribulation'.

In the past, the 'Divine Tribulation' he obtained from the Divine Heavenly Master's Cave Mansion had undoubted potential, and it was a transcendent method that could compete with any top-level imperial weapon technique in the world.

Zhang Xin even suspected that the power of this set of sword and sword weapons had surpassed the concept of 'supreme' and surpassed it.

Although Zhang Xin also knows that it is difficult to perfect it now, it will take a lot of time. However, because he had obtained part of the true meaning of 'slaying the divine tribulation', when practicing this method, he would also get twice the result with half the effort.

There is also the book "Taihao Golden Robbery", which is also very important, Zhang Xin is unwilling to give up his 'Golden Fighting Technique' and 'Gengshi Lux'. So I thought about whether I could create my own gold-based exercises, and use it to strengthen my own Fighting Saint Armor and Thunderbolt Type 8.

And this "Taihao Golden Robbery" can provide him with some inspiration.

As for the wind system, Zhang Xin also changed several copies and came back, all of which were used as references.

Although these six doors of the Seal Star Tower have no superior wind system Dafa, they are all very good. But as early as in his previous life, Zhang Xin had the idea of creating another wind method.
