"My lord, I dug up obsidian!".

"What, take me to see it".

The alchemy creatures guarding the mining area were overjoyed, obsidian was an incomparably rare existence in the alchemy universe, and this kind of ore could greatly increase the success rate of energy core inscription runes, and it was a treasure that could not be exchanged.

"Developed, haha".

Looking at the broken alchemy shovel and black ore on the ground, the alchemy creature was ecstatic, and began to take out his alchemy weapon, carefully digging at the obsidian, splashing huge sparks from time to time, and the runes on his body kept flickering, providing him with huge power.

"Almost".

After seeing that the runes on the surface of the opponent's body were a little dim, Sima Aotian quietly touched it from behind, and then punched the opponent to a position in the lower left, making the runes all over his body become disordered, and after observing for so long, he finally found the hub of the opponent's rune route.

"You!".

The alchemy creature turned its head in disbelief, then turned into a cold metal corpse and fell to the ground, the runes all over his body began to spread one by one, and Sima Aotian stepped forward quickly and began to secretly carve a smelting rune, melting the metal into a cloud of liquid.

"It must be successful."

He knew that he only had a little time left, and that it would not be long before there would be shifts of alchemy creatures coming to investigate, so his fingers began to move at high speed, carving a complex alchemy circle on the ground, and he jumped into it with the molten metal, this alchemy circle was not long after he deduced it, and he was not too sure at all.

"Hey, you're so lucky to have found obsidian while you're on duty."

"Haha, I've won a prize!".

When he was an hour, Sima Aotian, who had taken the form of an original alchemy creature, stepped on an alchemy spaceship, because he found that obsidian had merit, and a big man wanted to summon him.

"What a terrible energy fluctuation".

In front of several tall alchemy creatures, Sima Aotian knelt down respectfully and handed the obsidian up, although the other party did not activate the runes, he still felt the terrifying energy contained in the other party's body.

"Say, what reward do you want?"

"The little ones don't dare, it's enough to ask for some information on alchemy runes."

"Haha, interesting, it seems that you want to become a rune master, it's not that easy, I allowed you to stay in the alchemy tower for a month, and now it's too late for you to regret it."

"Thank you, thank you, little one, don't regret it."

Sima Aotian was overjoyed in his heart, and under the kind advice of an alchemy creature next to him, he learned that the Alchemy Pagoda was like the scientific and technological database of the Universe of the End of the Law, which was exactly what he needed at the moment, although he could also depict the runes himself, but compared to the runes in the Alchemy Universe, his was still too simple.

Now he is also an alchemy creature, but if it were a head-to-head duel, he would be the opponent of the alchemy guard who attacked him in the first place.

Knowledge is the sharpest weapon in front of those who are good at using it!

For a whole month, Sima Aotian immersed himself in the alchemy pagoda without sleep or food, absorbing the alchemy system of this universe, and when he came out again, he passed the assessment of the rune master on the same day, causing quite a stir.

"That little guy is quite interesting!".

After learning the news, the big man who had met him before smiled and decided to take a good look at Sima Aotian's potential.

In a series of complicated tests, Sima Aotian's potential shocked everyone, and even several respected rune masters fought on the spot, scrambling to accept him as an apprentice, Sima Aotian's genius name resounded throughout the alchemy universe, and there were even prophecies that he might become the greatest rune master of all time.

Sima Aotian did not live up to the name of genius, it only took three years for him to successfully engrave the runes on the energy core, all the runes engraved by his hands, the success rate reached an astonishing more than 90 percent, and all of a sudden, the name of Sima Aotian's first rune master resounded throughout the alchemy universe, and he also became a pivotal figure.

After casually finding an excuse to rescue the surviving humans of the end of the universe, he began to devote himself to the study of runes, and another three years passed, and the rune system of the alchemy universe changed by leaps and bounds under his improvement, and his prestige began to rival that of several of the strongest.

Ten years later, Sima Aotian engraved a set of top-notch runes for himself, and then dominated the entire alchemy universe strongly, and the human beings of the end of the universe also began to multiply, and poured into the alchemy system, and the two universes began to merge.

"The thread of cause and effect is gone!".

Li Yu's gaze was projected across multiple dimensions, and at a glance he saw the scene where the two universes began to merge, and Sima Aotian also felt something, and a trace of willpower flew out of his body and quickly returned to Li Yu's body.

"It's the only one that succeeds".

In the past two hundred years, Li Yu has made one attack after another, choosing more than a dozen hosts, but only Sima Aotian succeeded, but no matter what, the thread of cause and effect finally disappeared, which made him see hope.

Only those who are tainted with the breath of fate will be chosen as the host, but the chosen host may not be successful, and because of the interference of the power of cause and effect, every time he puts in a trace of willpower, it will fall silent for various reasons.

Trapped in the river of fate, he now has a lot of time, and the life-breaking clan of the universe in his body is under the effect of the bronze order, and the Heavenly Dao origin is more and more, and his will power has become extremely large, in this case, there is no need to worry about the consumption of will power, Li Yu began to choose the host again and again, and the thread of cause and effect that entwined him became less and less.

Ten thousand years have passed, the last thread of cause and effect that entangles him has also disappeared, and an incomparably clear feeling rises from his heart, and he finds that his perception of the Great Dao has become clearer and clearer, and in these ten thousand years, due to the absorption of countless Heavenly Dao Origins, his will power has become incomparably huge, and even the universe he has transformed has expanded more than a hundred times.

But in the process of cracking the line of cause and effect, Li Yu found that something was wrong, all the hosts that were not contaminated with the power of fate failed in the end, with his current strength, there were strict restrictions on the choice of hosts, and he was able to become the host of high-dimensional life at the beginning, because rebirth was contaminated with the breath of fate.

But the point is, why was he born again?

Creating a reborn in a universe tainted with cause and effect is something that even with an immortal-level superstring weapon can't do, let alone an ordinary high-dimensional life with only a mechanical heart.
