Under the magical civilization, there is no need for advanced industrial design skills, just use a little fur to achieve incredible achievements.

Gu Tiancheng certainly has the spirit of dedication to science. The first one tested himself. Carefully take out a little bit of Tianyi dust water, and use the Yin and Yang Five Elements Shield to forcibly absorb it into the body.

Then start to experience the sensation with your eyes closed. As soon as the dust and water entered the body, the annihilation attribute was completely stimulated. Gu Tiancheng had to use the spiritual power of his whole body to resist.

It is also thanks to Gu Tiancheng that he has already stood firm in the Yin and Yang Rank, and the toughness of his spiritual power is very strong, and he is in his home field, no matter how much he is annihilated by Tianyi dust and water, there will always be more spiritual power to fill the hole one after another.

Gu Tiancheng was very calm during the whole process, he knew that this was not a bottomless pit. If you inhale a little bit of dust and water by yourself, it is impossible to drain yourself.

Gu Tiancheng just wanted to know what Tianyi Dust, who no longer annihilated the spiritual power around him, looked like. Just knowing this, he tested the water, Gu Tiancheng is really good enough to study madness in scientific research.

The Annihilation attribute can be annihilated regardless of whether your spiritual power is at the Five Elements level or the Yin and Yang level. The only difference is that the Yin-Yang level spiritual power can support it for a longer period of time under the annihilation attribute of Tianyi Dust Water, and that's it.

A drop of water was not enough to crush Gu Tiancheng. In less than a quarter of an hour, the annihilation attribute of Tianyi dust and water was significantly weakened.

Gu Tiancheng was overjoyed in his heart, and began to mobilize more spiritual energy to pounce on it, to feed Tianyi dust and water as soon as possible.

Soon, the dust and water of Tianyi changed from the original bleak and dull to a pure blue state, exuding a holy brilliance outward.

Gu Tiancheng carefully escorted Tianyi Chenshui to the dantian, and the spirit core accepted Tianyi dust, carefully feeling the reaction of the spirit core.

The spirit core did not have any rejection of Tianyi dust water, after all, Tianyi dust water absorbed Gu Tiancheng's spiritual power.

Seeing that they were safe and sound, Gu Tiancheng made another abnormal move and began to urge the spirit core to try to absorb the drop of Tianyi dust water.

The absorption process is very quiet, and there is no overreaction to the dust and water in the sky. But Gu Tiancheng obviously felt the difficulty of absorption, and it often took a lot of effort, but he could only gain a little.

If it weren't for the fact that Tianyi dust water had already absorbed Gu Tiancheng's spiritual power, I am afraid that Gu Tiancheng would have paid more strength, and he would not have thought of absorbing Tianyi dust and water.

After inhaling a little bit, Gu Tiancheng began to experience the changes in the spirit core with his heart. Although it is only a little bit, it has already made the spirit core full of vitality, the frequency of activities has increased significantly, and the decomposition and fusion of the spiritual power of the yin and yang attributes have also been much faster.

Gu Tiancheng was overjoyed: It's really a good thing!

Gu Tiancheng was encouraged, and began to slowly absorb and digest the drop of Tianyi dust water very patiently. It took two days to completely absorb the drop of Tianyi dusty water.

With one more drop of Tianyi dust water, Gu Tiancheng's spirit core appearance was already faintly emitting blue light, and the ability of the spirit core to deal with spiritual power was increased by three times!

What is even more gratifying is that the spirit core even initially possesses the ability to generate spiritual power on its own! It is worthy of being the source of all things. Just one drop can create such a miracle.

The ability of self-generated spiritual power is inconspicuous at first, but the self-generated spiritual power is completely its own, just like the innate exercises, it is completely one's own, and there is no need for any exercises and combat skills, and the spiritual power can be completely manipulated by consciousness alone.

Moreover, self-generated spiritual power can also transform other spiritual powers into their own. This is terrifying! If Gu Tiancheng's cultivation is all replaced by self-generated spiritual power, then Gu Tiancheng's achievements are similar to Gu Ling'er, and he can make any moves he wants, and he is completely not restricted by exercises and combat skills.

This is a beautiful vision, of course it is better to realize it, and Gu Tiancheng is not discouraged if it cannot be realized. With his own spiritual power, it was already a reborn change for Gu Tiancheng. Gu Tiancheng doesn't have extravagance, he has to be on par with Gu Ling'er.

Tianyi dust water is so good, do you want to absorb a few more drops? Gu Tiancheng hesitated for a long time, and finally suppressed this strong impulse: One drop may be fine, but no matter how much it is, it is not guaranteed. Quantitative change leads to qualitative change, and Gu Tiancheng understands this truth.

At least now, Gu Tiancheng has figured out the purpose of Tianyi dust water: it is used to transform his own spiritual core. Although the strength of the transformed spirit core has greatly improved, Gu Tiancheng doesn't want to let others try it right away.

They don't have as much fault tolerance as themselves. After all, he is an innate exercise, even if Tianyi dust water is poisonous and harmful, the range he can withstand is far stronger than theirs.

It's better to observe for a while, have a deeper understanding of Tianyi dust and water, and then take it out for practicality.

The Allen faction has Allen's exercises, Allen's archery skills, and the Demon Gathering Banner to assist in advancing to the Yin and Yang ranks. It's strong enough. For the time being, there is no need for a dust of water to add to the icing on the cake.

However, it is a good choice to give Gu Ling'er some and let Gu Ling'er try it.

As soon as Gu Tiancheng thought of this, he immediately summoned Gu Ling'er, handed him a drop, and asked him to digest it with all his might.

Gu Ling'er knew Gu Tiancheng's changes, swallowed it happily, and then sat down cross-legged, and soon a thick spiritual mist rose around her body.

I have to say that Gu Ling'er's strength is far stronger than Gu Tiancheng's, but as soon as she made a cup of tea, Gu Ling'er jumped up and asked Gu Tiancheng again in a hurry.

Gu Tiancheng was afraid that something would happen, so he didn't dare to give more, and only gave one drop at a time. As a result, Gu Ling'er asked Gu Tiancheng dozens of times, and finally Gu Tiancheng lost patience and gave him a small bowl at a time, which sent this god away.

Gu Ling'er is Gu Ling'er, absorbing so much at one time, not only did she have no side effects at all, but her whole body began to emit divine brilliance, with a faint blue halo around her body!

Gu Tiancheng asked him what the effect was. Gu Ling'er told Gu Tiancheng that he originally needed to continuously absorb spiritual power to maintain his cultivation, but now that he has Tianyi dust and water, he doesn't need it. Self-generated spiritual power can form a complete system in the body to maintain the balance of its own consumption.

Moreover, Tianyi Dust Water also gave Gu Linger another skill: the perfect clone!

Previously, Gu Ling'er could also clone herself, but no matter how many clones there were, the main control was only the main body. All clones are subject to the control of the Body.

But with the blessing of Tianyi dust and water, Gu Linger further comprehended, or epiphany, the perfect doppelganger function.

A perfect doppelganger means that the doppelganger has an independent consciousness and will, is not controlled by the ontology, and is the same as the ontology.

Moreover, the strength of the perfect clone is generally the same as the ontology. The main body does not reduce the strength of the main body because of the clone!

This is the magic of Tianyi dust water!

Gu Tiancheng was dumbfounded when he heard this, and asked Gu Ling'er to demonstrate on the spot, and asked Gu Ling'er to open a channel of communication with his soul.

Gu Ling'er separated an identical doppelganger in the same way, and the two Gu Ling'er stood in front of Gu Tiancheng with a smile.
