Li Ci added dozens of Snickers, and the energy food composed of cocoa and nuts is still very powerful.

At the same time, Xiao Lun's heart, which had been squeezed because of the carotid sinus, began to beat wildly after a small amount of the mysterious substance leaked. It wasn't until Li Ci completed the drawing of the "Xia Dantian" energy corridor and locked the mysterious substance in the energy corridor that he slowly returned to normal.

This evolution, or intensification, was not supported by much energy because the time was too short. Xiao Lun should have passed the most difficult level now, and there are even more difficult things waiting for him in the future.

The door to evolution has been opened, and now it's a matter of how to keep it within acceptable limits. But the rate of evolution that each person can accept, or the amount of lethality that the mysterious substance can cause to each person, is different. The amount of mysterious substances that Li Ci was able to accept before was not the same as what he was able to accept now, which had a lot to do with everyone's physique.

How strong the mysterious substance stimulation Xiao Lun's body can withstand is still to be determined by testing.

But the priority now is to make sure that there is no mortal danger. So, our protagonist has to go all out and complete the energy rune between the eyebrows. The purpose of this rune is to limit the energy shock and prevent irreversible damage to the brain caused by excessive shock.

The purpose of the rune is very clear, but the specific method requires Li Ci to design it with great effort.

First of all, the strengthening of the brain requires energy, which is our original purpose. But too much energy is dangerous, so we need to reduce the supply of energy. But the strengthening of other parts cannot be delayed, which is a problem.

In the end, Li Ci decided to set up an energy storage device at the bone between the eyebrows, which was the storage rune. A certain amount of mysterious matter and energy is transmitted to the brain through this rune to achieve the purpose of controllable sexual enhancement.

This section is made up of stored and restricted runes, as well as a network of energy distributed throughout the cerebral cortex. Storage and restriction are not a big problem, because this is all in Li Ci's genetic knowledge, and it is okay to do this. But the energy network distributed in the cerebral cortex is very difficult, because the amount of work is staggering.

The human brain is one of the most delicate parts of the human body, especially the cerebral cortex, which has the strongest responses. The cerebral cortex is the most fragile, so it needs to be protected by a hard skull. And the energy network has to pass through this fragile cerebral cortex, and this degree of rigor is a higher level than that of the "little sun".

The folds and sulcus of the cerebral cortex need to distribute energy networks to play a final strengthening role. So you can imagine how huge this energy network is all over the brain, and how long it will take Li Ci.

It's 3:40 a.m., and it's not difficult to build the "little sun", it's just a few seconds to build the corridor. So it didn't take long.

What Li Ci is doing now is really time-consuming and energy-consuming, the construction of the cerebral cortex energy network, which will take a huge amount of time.

After replenishing his energy, Li Ci is about to start working!

The first thing to do is to form an energy core on the bone between the eyebrows to receive and store the energy transmitted from the heart, which is relatively easy.

The energy between Li Ci's eyebrows began to fluctuate violently, his eyes instantly became confused, and the energy that burst out of Xiao Lun's heart with the blood, under Li Ci's deliberate guidance, meandered upwards from the pulmonary artery and blood vessels to the brain.

The human brain needs a huge amount of oxygen, and this is something that everyone knows. When the human heart stops beating, the first thing to be injured is none other than the brain. Therefore, the blood vessels that transport blood in the pulmonary arteries are high-speed express trains that can reach the brain directly.

The special fluctuating energy rushed along the blood vessels to the brain, and in Li Ci's deliberate guidance, the energy finally converged in the capillaries of the bone between the eyebrows. The violent vibration of the energy collapses the blood vessels, and the energy circuit of the special vibration frequency is forcibly imprinted on the bones. A special red pattern appeared between Xiao Lun's eyebrows, which was the trace of the collapsed blood vessels of the energy circuit.

The pattern is very beautiful, and the diamond-shaped red mark scatters four blood-red lines between the eyebrows, extending towards Xiao Lun's forehead and even his head, and finally wrapping Xiao Lun's entire skull in a network composed of four red lines, forming the tightest protective circle.

Now that the lines for storing and transmitting energy have been completed, the next step is to build a rigorous energy network in the cerebral cortex. Or the capillaries that branch out of the pulmonary arteries, the lines that supply oxygen to the brain.

The energy frequency was pressed to a very low level by Li Ci, which was harmless to the cerebral cortex, but the traces of the inscription were very faint, and it took dozens or even hundreds of times of blood to carry the energy to repeat the drawing.

Due to the countless blood vessels in the cerebral cortex, the running lines are also the simplest and most effective that Li Ci has carefully selected, and they must conform to the rules of rune technology to take effect.

This time the energy depiction does not consume much energy, but the operation is more refined, and Li Ci enters that mysterious state, at this time he is like a rune master. Rigorous and precise, the energy fluctuations are extremely well controlled, and there is definitely the style of a rune master!

(In fact, Li Ci's genes do not have any impression of the rune master, these are all imaginary by the author...... Haha)

Time kept passing, and under Li Ci's subtle control, the energy crossed countless circles in Xiao Lun's brain, and finally the lines of the runes were firmly engraved in Xiao Lun's brain.

Exhaling softly, Li Ci's blank eyes finally returned to normal. This time, the portrayal lasted for three hours, and Li Ci's mysterious state also lasted for three hours.

In fact, Li Ci had already guessed! When Zhao Xin first encountered a Void-level gluttonous warrior in Tonghu Town, he was beaten and had no power to fight back. In the end, he forcibly turned on the Void Engine, rewrote Zhao Xin's genes, activated the super gene of Zhao Xin's "Dexing Spear" and opened his gene lock, and Zhao Xin completed the single kill.

Yes, it's the gene lock. If Li Ci remembers correctly, this kind of lock of human evolution set by Zhang Heng did appear in the world of the Super Divine Academy.

The gene lock is divided into several layers, and Li Ci doesn't know it, because Z Da didn't explain it clearly in his work. However, there are known to be six layers, and only four layers are actually reached.

Zheng Zhe in Infinity, a fourth-order high-level genetic lock, with strengthening, has become one of the existing bugs in the infinite world. The personal combat power is enough to reach the level of star destruction, which is like a god in the world of the super divine academy.

If Li Ci remembers correctly, the state of opening the first layer of the gene lock is like this. When you need to be someone, you can do what you want to do perfectly.

To put it more simply, when you need to be a fighter, you will become an experienced fighter to the extreme, and you will always be the one who survives in the end. When you need to become a scientist, all your knowledge will be put to good use to the limit of what you can do......

Just like that, Li Ci needed to become a rune master, so the first layer of his gene lock turned him into a master who perfectly mastered the knowledge of existing rune technology.

The use of this ability was not easy, and Zheng Zhe almost died when he first opened the gene lock in Infinity. And Li Ci, with the support of his strong physical fitness, also broke out in a cold sweat, and his whole body was soaked.

Xiao Lun did not suffer any pain under Li Ci's sophisticated and subtle technique. Now Li Ci needs to take a break, replenish his energy, and meet the final challenge in the most perfect state.
