Selling blood and starting with 150 billion cosmic spars, Xue Fei is also considered a small wealth, although this wealth is far from enough to buy the secret technique of the law, but with Xue Su's current status as a fifth-class elder, with an annual salary of 50 million cosmic spars,

A few drops of blood, in exchange for 3,000 years of wealth, can be described as a small profit.

"In the next period of time, don't run around, stay in the primordial mountain and cultivate, with your talent, cultivate for hundreds of thousands of years, the true god can be expected!"

The three ancestors explained and left, leaving only Xue Yu to stay in the ancestral ancestral mountain.

"Now that the true dragon bloodline has been exposed, there will be great danger if I rashly step out of the evolutionary plane, I will first successfully cultivate the doppelganger technique, and then say, with the doppelganger, the universe can go."

As soon as he thought of it, Xue Jun found a quiet place, and then began to study the Flash Sky Recovery.

"The Flash Resurrection is completely different from other doppelgangers, other doppelganger techniques are splitting, while the Flash Resurrection is replication, replicating cells, replicating organs, and then re-replicating a body, and finally replicating the soul......"

In this way, Xue Fei began to cultivate the doppelganger technique, it is difficult to cultivate the lightning and restore the god, and when he practiced for the first time, Xue Fei encountered various problems, but how weak was Xue Fei at that time?

Soul strength is far from enough.

Now it is different, after four transformations of the laws of the universe, his soul crystal nucleus has been strengthened tens of thousands of times, and both his deduction ability and calculation simulation ability have undergone earth-shaking changes.

In the past, it took a long time to replicate a cell, but now, it is not a problem to replicate tens of thousands of cells at the same time, so it can be said that as long as he is given time, sooner or later he will be able to practice the top-level clone technique of Flash Sky Resurrection.

But Xue Yu didn't plan to do this, he decided to try according to the idea provided by Xiao Jin: cultivate a cell, and then provide energy, nutrients, and the kind of cosmic laws related to the void, so that the cells can multiply on their own.

"Proliferation is the instinct of cells, but in the process of proliferation, many cells will automatically differentiate and form various organs, and I obviously can't allow this kind of thing to happen......"

In this way, Xue Jun pondered little by little and began the cultivation process of cells.

The first time, the cultivated cells were not properly nourished, and the cells died before they could begin to divide.

The second time, the nutrients and energy are suitable, but the cells divide twice, and after becoming four cells, they no longer continue to divide.

Third ......

Failure after failure, accumulation of experience again and again, maintenance time is getting longer and longer, cell division is more and more times, and the number of accumulations is also increasing.

100, 1000, 10000......

Time passed imperceptibly, and in the blink of an eye, 10 years passed leisurely!

"Bang-"

A "piece of meat" filled with blood mist suddenly exploded, blood splashed, and Xue Jun was splashed all over his body, and he smiled helplessly: "Failed again, alas! ”

"Come again!"

Keep trying, this attempt, another 10 years!

"Not a single cell has divided for 3 days, and it looks like this embryo sac is dead again!"

Xue Jun sighed, his eyes were bloodshot: "After all the hard work to cultivate the embryo sac, it is only 2 steps away from developing into a fetal heart, and the fetal heart is ...... Alas, forget it, let's start over, anyway, after accumulating experience, it won't take long to start again! ”

So, Xue Jun waved his hand to erase the dead embryo sac and began another attempt, this time, he extracted a cell, as before, to create a suitable environment for it to divide.

The cells continued to divide, the number became more and more, and after a few hours, a large mass of cells was formed to form the cell body, at this time, Xue Yu immediately changed the environment, nutrition and energy quickly switched, and the laws of the universe also hurriedly followed.

The cell body began to proliferate, differentiate, and a day later, another embryo sac was formed!

"In the past, it took me 20 years to get to this point, but now, one day and a few hours, I have successfully cultivated it!"

Xue Yu's heart was full of waves, without a trace of joy, all of this was the result of 20 years of continuous failure and continuous exploration, which was deserved, not worth being happy.

"Last time I failed here, the embryo sac did not move for three days, this time, you must be careful, as long as the embryo sac develops into the embryo, it is a big step forward from victory!"

Embryo sac - germ - fetal heart......

As long as the germ is formed, the rest of the process is simple, because from the germ, the ratio conditions composed of nutrition, energy, and the laws of the universe are almost identical, that is to say, as long as this environment is maintained, the germ can complete its development by itself, and there is no need for Xue's deliberate manipulation.

Just like a plant that breaks through the soil, as long as it sprouts, it is much simpler, absorbing sunlight, rain and dew, and growing naturally.

"It must be successful! This time it must be successful......"

Xue Yan was engrossed in his attention, his concentration was highly concentrated, and his soul power completely locked onto the embryo sac, while paying close attention to the changes in the environment to ensure that nothing went wrong.

The embryo sac develops little by little, specific cells begin to differentiate, and finally, after half a day, a bud-like structure emerges, grows little by little, and the germ develops successfully.

"It's done!"

"The germ is made!"

Rao was in Xue Yu's state of mind, and he couldn't help flashing a trace of fluctuation, but he didn't dare to be careless, and continued to concentrate on it, and the power of his soul recorded the development process of the germ, such as which cells were differentiating and differentiating......

The germ continues to develop, gradually matures, and at the same time, the brain begins to develop, and after a while, the heart begins to develop, and the cells are quickly in place, and then differentiated, and finally, the heart develops successfully.

Fetal heartbeat, successful development.

"Whew~~~"

At this point, Xue Jun let out a long sigh of relief, and then waved his hand to erase the replica that had developed to the state of fetal heartbeat, with a long-lost smile on his face.

"At this moment, the whole development process is basically more than half, I have all the experience, and the next step is much simpler, wait for me to relax, use the best state, and create the most perfect replica!"

Many things, of course, are the more times you do it, the more comfortable you are, and the more experienced you are, since you want to cultivate the Flash Void Resurrection, Xue Xue naturally hopes to cultivate the most perfect replica.

Therefore, he had to do it in the best state, and if it was even possible, come a few times, and then choose among the multiple replicas he had cultivated, and choose the best one.

"Relax, rest, and start when you're almost done!"

Resting almost, Xue Fei began a new round of manufacturing, this time he was full of confidence, believing that he could succeed in one fell swoop, from the cell to the complete replica.
