After the evolution of the galaxy stabilized, Cao Xianzhi stretched out two fingers (claws) and gently rubbed them, and a comet was formed.

The next thing is simple, the comet slams into the planet most likely to give birth to life, sending precious water to that planet.

Originally, Cao Xianzhi wanted to directly create water sources, but after thinking about it, he gave up this plan, and he was not in a hurry, so why not make the evolution process of this planet more comprehensive.

With water on the planet, there is the basis for the birth of life, and under the acceleration of Cao Xianzhi's time, a few days later, single-celled organisms appeared in the ocean, these single-celled organisms evolved from prokaryotic cells, and there was only a faint aura, and there was no wisdom at all.

After a few days, algae plants and a small number of multicellular organisms appeared in the ocean, such as jellyfish, small worms, etc., Cao Xianzhi did not let the aura appear on this planet in order to do experiments, so the process of biological evolution, except that the species is not very different, is not much different from the earth.

A month later, trilobites, primitive fish, and the apex predator appeared on the planet, a large worm up to four meters long, which Cao Xianzhi called Cao's worm.

Cao Xianzhi grabbed a few Cao's worms and put them in the container he had refined, and it was obvious that this worm had become one of his experimental materials.

Life continued to evolve, and as time passed, there were more and more creatures in the ocean, and the competition became more and more fierce.

This evolution did not stop until the appearance of a giant shield fish in the ocean, because at this time Cao Xianzhi thought that the experimental materials he had collected were enough.

After Cao Xianzhi stopped the time of the galaxy, he put it aside, picked up the container of creatures he had refined before, and looked at the strange creatures inside, he thought about grabbing a Cao's worm with his divine thoughts, and then used his divine thoughts to pinch a grain of chaotic aura, and slowly approached the Cao's worms.

As for why this unit of measurement is used, it is because in the previous observation, Cao Xianzhi found that the Chaos Aura is indeed a highly active particle the size of an atom, which can strengthen the Yuan Shen and evolve the physical body after absorption, of course, the premise is that your physical body is strong enough to resist the destruction of the physical body by the irritable Chaotic Spiritual Qi particles, otherwise, your physical body will explode with a "bang" like a blown balloon, which is why Chaotic Spiritual Qi is an indispensable resource for high-level cultivators, It is also the reason why low-level cultivators avoid poison.

Sure enough, just a few minutes after Cao Xianzhi fused the Chaos Aura Particles and the worm into one, the worm exploded.

"Sure enough, this high-grade Chaos Aura is a deadly thing for ordinary creatures." Cao Xianzhi looked at the results of the experiment with some emotion.

He experimented with several other more advanced creatures, but none of them survived, and all of them were torn apart by the Chaos Aura particles and died.

Cao Xianzhi saw that the results of the experiment were almost the same, so he stopped continuing the experiment: "Is it still the reason why the body is not strong enough?" But now that I'm staying there's not even an innate aura, let alone the acquired aura cultivated by ordinary creatures, do I have to hang on to these creatures if I want to continue experimenting? ”

Cao Xianzhi didn't want to do this in his heart, he hoped that those creatures could evolve on their own, instead of being strengthened into immortals by him all at once.

"Hmm...... Wait, I seem to have overlooked something...... By the way, since aura can be used for cultivation, can thunder, lightning, and heat energy also be used for cultivation...... It's worth a try. Cao Xianzhi seemed to suddenly open his mind, and his thoughts suddenly spread, pouring out a lot of wonderful ideas.

Taking advantage of this opportunity, Cao Xianzhi immediately began to deduce the exercises, and he didn't even care about the experimental materials.

Five years later, Cao Xianzhi opened his eyes: "Huh, I didn't expect that electric energy can really be used for cultivation, it turns out that it is not that those cultivators who are trapped in the world of the end of the Dharma era have bad brains, but because they are not cultivated enough and fall into misunderstandings, they did not expect or have no ability to create exercises for cultivating with electric energy and heat energy, but what I am more curious about is that before that, why didn't the immortal Buddhas who had predicted the end of the Dharma era create exercises that could be practiced with common energy such as electric energy, but went far away, I am afraid that they will lose their minds." ”

Cao Xianzhi sighed, he really couldn't understand the thoughts of those immortals and Buddhas, one world ran to another world without aura, this kind of behavior was no different from ZZ in his opinion, he obviously had the ability to explore the origin of the world and open up other cultivation paths, but he was content with the status quo, even if he fell into a vicious circle, he could turn a blind eye.

"I still can't understand the thoughts of those immortal Buddhas, even I, a chaotic god and demon with a fifty-fold chaos element, are doing research, those little guys who haven't even broken through the chaos yuan Daluo Jin Immortal actually dare to eat and wait for death, heh, and those protagonists, the cultivation that has been strengthened by the system is embarrassed to pretend to be forced! It's depressing to think about, how many people are still as hard as me with the system? There is no enhancement, no task, only endless cultivation ......" Cao Xianzhi shook his head and stopped thinking about these sad things, he picked up the container again, caught a shield fish, and continued to experiment.

Cao Xianzhi looked at the shield fish in his palm, and carefully used his divine thoughts to help it expand the sea of consciousness and strengthen its spiritual power.

After the spirit of the shield fish was strong enough, it slowly teleported the "Thunder Decision" he created into its mind.

After doing all this, Cao Xianzhi ingested some iron ore on the planet he created, and after extracting the iron, he assembled a hand-cranked generator, shook the generator, injected the released electricity into the body of the shield fish and guided it to run exercises to absorb electricity

Cao Xianzhi's conjecture succeeded, and with the help of the exercises, the cells of the shield fish slowly absorbed the energy of electricity to strengthen the body.

"In this way, my experiment is half the success, although the experiment on Chaos Aura basically failed, but I also created a method of cultivating with electric energy, and my exercise can finally continue to improve." Cao Xianzhi took out the "God and Demon Quenching Decision" from the depths of the sea of knowledge and continued to improve it.

First of all, he deleted the "strong external stimulus at the beginning, and can only continue to cultivate by repairing itself by relying on the treasures of heaven and earth", and changed it to thunder and lightning quenching, so that as long as it is not too intense, there is no need to consume too much heaven and earth treasures to repair itself, and by the way, he also added a design drawing of a hand-cranked generator very intimately, so as to avoid that someone can only rely on being struck by lightning to practice when someone gets this exercise in the future.

However, it is not so easy to modify the exercises, and if you change the front and back, you have to change it, so Cao Xianzhi, who had just finished the experiment, fell into the big pit of modifying the exercises after putting the experimental materials into the system space, but he was tired of looking at him, and he completely took this matter as a hobby.
