I don't know how long it took, the wind finally stopped, and Li Yu, who had re-transformed into a human form, found himself in a constantly flowing river of will, in which strangely shaped polygonal objects shuttled back and forth, like fish swimming freely in the river.

"What is this?".

He began to grasp it with his hands, but these things flowed rapidly under the wash of the river, and the water of the will interfered strongly with his perception, and after several attempts, he found nothing but the river that quickly dissipated in his hands.

"Multidimensional Fragments!".

Li Yu, who did not give up because of this, happened to run into a dead mouse and grabbed a small hexagonal object, and then he found that this was the multi-dimensional fragment needed to improve the level of the mechanical heart, and there were many more such things in the River of Will.

"Finally something good happened."

Li Yu laughed loudly, and with perseverance began to salvage the multidimensional fragments and throw them all into the cosmic prototype in his body.

"Refining!".

After accumulating enough multidimensional fragments, he used a large amount of the power of fate to wrap the Heart of Machinery, preparing to sacrifice it directly to the legendary level.

The extremely rich superstring power automatically emanated from the mechanical heart, and gradually spread into the primordial universe, some high-dimensional beings sensed the fluctuation of the superstring power, revealing extremely puzzled eyes, it stands to reason that the time before the next superstring weapon was born, it shouldn't be so fast?!

These high-dimensional beings native to the primordial universe began to approach the river of will rapidly, and Li Yu's will was immersed in the inner universe and knew nothing about the outside world.

"Boom".

A large amount of superstring power wrapped him, reflecting a low-dimensional world, and in the prototype of the universe in his body, dozens of multi-dimensional fragments slowly melted, and penetrated into the mechanical heart together with the power of fate.

Although the sixth dimension is composed of the power of will, but this power of will is often extremely violent, and high-dimensional beings rarely absorb the power of the will of the sixth dimension to improve their strength, because this progress is too slow, and the most common way is to use super-string weapons to devour the power of the Heavenly Dao Origin of the low-dimensional universe to quickly strengthen themselves, which is also the reason why they attach great importance to super-string weapons.

Hero-level super-string weapons can only find the low-dimensional universe through repeated attempts, and it is impossible to find out if there is a half-step high-dimensional life in it, once there is a rebellious creature like Li Yu, the super-string weapon they have worked so hard to obtain is very likely to be lost, and the owner of the mechanical heart is like this, and now he doesn't know where to hide and cry loudly.

The Legendary-level Superstring Weapon is different, it can not only manifest the cosmic coordinates at low latitudes, but also be able to probe the situation inside through the will, so that absorbing the Heavenly Dao Origin will become extremely safe.

After absorbing the power of fate and multi-dimensional fragments, the mechanical heart, which was already at the peak of the heroic level, transformed, and a trace of more advanced superstring power distorted the surroundings, and Li Yu got a lot of information about the low-dimensional universe in his mind.

"It worked!".

Li Yu opened his eyes suddenly, and the mechanical heart automatically flew out of the surface of his body, and began to help him locate the low-dimensional universe that could absorb the origin of the Heavenly Dao, and at this moment, more than a dozen vague figures flew in from outside the cave, revealing an incomparable shock in the fluctuation of will.

"Legendary Superstring Weapon!".

These high-dimensional beings of the primordial universe were stunned, they didn't expect this rare treasure to appear in front of them, and their will was condensed into substance, and they swept over at the heart of the machine.

"Not good".

Looking at the huge figure approaching from a distance, Li Yu could guess with his ass that this was a high-dimensional life that was much stronger than him, but fortunately, the heart of the machine had already been refined by him, and his mind was withdrawn into the prototype of the universe in a moment, and he gathered the power of the will of his whole body and quickly rushed towards the river in front of him.

"Bang!".

An incomparably huge splash of water rose on the surface of the river, and several powerful willpower struck Li Yu, and his willpower was turbulent for a while, and then he sank to the bottom of the river unconsciously, and was constantly washed forward by the turbulent river of will.

"Plop, plop!".

A large number of high-dimensional beings jumped into the river, due to the barrier of the river of will, although their willpower was strong, they could not detect Li Yu's traces, but when they thought of the legendary superstring weapon, their will fluctuations became unstable, and each figure swam forward quickly, still holding a trace of luck in their hearts.

"It's a half-step high-dimensional life!".

Some pursuers sighed in their hearts that it had been a long time since there had been a low-dimensional half-step high-dimensional life leap in the primordial universe, and there was once a person named "Pangu" who appeared, and even later made a great reputation, but this was all a long time ago.

In the river of will, a huge whirlpool brought Li Yu into a dark river, dozens of high-dimensional beings who swam to the vicinity passed by him, and Li Yu, who did not know that he had escaped, followed the dark river and emerged from a large pool under a waterfall, and the power of will contained in the waterfall was even more violent, and he woke up in an instant.

"I'm careless!".

Feeling his weakened willpower, he smiled wryly and struggled to crawl out of the waterhole, and he entered the deep valley.

"Why are there so many eggs?!".

Thousands of giant eggs of different sizes were placed in the valley, slowly absorbing the power of the tyrannical will of the primordial universe, Li Yu knocked one of them open with doubts, and a true god-level powerhouse fell out of it, and without the protection of the eggshell, the true god-level powerhouse exposed to the sixth dimension was annihilated instantly, leaving no trace.

"It turns out that the high-dimensional beings of the primordial universe are all conceived by true god-level powerhouses at low latitudes!"

Li Yu's heart was shocked, according to this gestation speed, it would be thankful that one or two high-dimensional beings could appear in the endless years, fortunately, he had previously refused Chu Hanyun and Jiang Yuyao to accompany him to the primordial universe, otherwise the two of them would probably have to stay in these eggshells like living fossils to spend a long time.

"Why hasn't my Great Dao Tribulation come yet?"

After seeing the power of high-dimensional life, Li Yu was eager to transform, and now his half-step high-dimensional life strength couldn't even protect himself in the primordial universe, let alone compete for superstring weapons.

"The bottleneck is gone!".

In the process of using the Heavenly Dao Origin that the Machine Heart had collected before to quickly recover from his injuries, he was pleasantly surprised to find that the bottleneck that bound him in the initial universe had disappeared, and there was no longer any restriction on the transformation of the Heavenly Dao Origin.

After finding an inconspicuous location, Li Yu began to cultivate frantically.
