With the explosion of the concentrated energy vortex after reaching the critical point, those highly compressed energies instantly washed away Qi Lin's whole body like a torrent of blood, and the capillaries on the surface of Qi Lin's skin were completely unable to withstand such a violent impact, and they exploded one after another, and a large amount of blood seeped out of the pores, instantly dyeing him into a "blood man".

Not only the capillaries, but even some of the more fragile blood vessels have burst open, but these blood vessels have just been destroyed by the violent energy impact one second, and the next second they thought that they were healing at an extremely terrifying speed, and these new blood vessels have become more tough and strong than before they were destroyed.

Qi Lin's current blood pressure in his body, under the effect of violent energy, can no longer be described by the word "high blood pressure", if you use that old-fashioned mercury sphygmomanometer to measure Qi Lin's blood pressure, I am afraid that the mercury in the glass tube will rise to the highest point in an instant, and then the top of the glass tube will be cracked.

Qi Lin felt like a boat in the middle of a storm now—no, no, he didn't even have a boat, to put it more accurately, he was a man overboard in the midst of a raging ocean, waves of powerful energy that continued to pass over his head and slap heavily on him.

The whole process of breakthrough can be described by the word "miserable", and the degree of pain is not known how many times stronger than when he fused the Corpse King Serum at the beginning, but Qi Lin's spiritual willpower has also made great progress, and he can't pass out at all, so he can only bear this inhuman pain silently.

The skin, muscles, blood vessels, nerves, and even organs and bones on his body were almost destroyed and reshaped, and the dirty blood, mixed with impurities and waste products stripped from his body, formed a thick layer of blood scabs on the outside of Qi Lin's body, like a dark red humanoid blood cocoon.

A crack suddenly appeared on top of the blood cocoon, followed by the second and third...... More and more cracks appeared, and finally, the entire blood cocoon shattered into pieces, and a "brand-new" Qi Lin appeared in the underground cavern.

At this time, Qi Lin, although his appearance and appearance have hardly changed, but if you look closely, you can see that his skin has become very delicate, and the muscle blocks hidden under the skin are not as developed and exaggerated as the bodybuilders, but they are full of terrifying power.

Qi Lin raised his right hand slightly, and a punch slammed into the ground, accompanied by a muffled sound, and a fist mark more than two inches deep appeared on the permafrost soil that was as hard as steel.

This is still the result of Qi Lin only using two percent of his strength.

If Qi Lin was willing, with this punch, he could even plunge his entire arm into the hard frozen soil!

Raising his hand, although the skin on the surface of the fist looks more delicate than a woman's, the toughness is not much different from that of a powerful mutant creature leather.

"That's what it is...... Fourth-level Evolutionary ......"

Closing his eyes and feeling his own state, the energy contained in the original concentrated energy vortex has now become a part of Qi Lin's body, like a tide that spreads all over his body, constantly rising and falling with his breathing.

And in his chest and abdomen, the huge shaped vortex had disappeared, and in its place was a small, but much more refined small vortex, this small vortex did not rotate fast, but with each rotation, it would faintly emit a wave containing great destruction.

Qi Lin glanced at the attributes displayed by the Zhi Brain, and compared with the time when he was at the third level, the physical fitness of the fourth-level evolutionary was once again enhanced by a leap.

Strength 39, Agility 36, Perception 45, Stamina 60, Radiance 181, Satiety 37, Hydration 22, Health 5000.

As Qi Lin expected, although he did not gain new abilities in this evolution, almost all of the original abilities were strengthened, and his health directly increased to 5,000 points.

The upper limit of the new energy storage value has reached a terrifying 200,000 points......

In other words, like the quail egg-sized crystal before, Qi Lin needed to absorb more than a hundred before he could break through the "critical point" of a fifth-level evolutionary.

Although it is a shortcut, if you want to take a shortcut, the price you need to pay is very huge.

"Depressed! Why did I kill all these young creatures—"

Qi Lin suddenly slapped his head with some remorse, if he could just leave a larvae, find a way to send it to base 404 for Cooper to try to domesticate it, if it can be domesticated successfully, as long as there is enough radioactive ore, this larvae can provide Qi Lin with a steady stream of purification crystals.

Purifying raw bituminous uranium ore into such an incomparably pure crystal, a technology that even humans have not yet mastered - that is, this crystal, which can only be produced by these monsters, and beyond that, there is no way to obtain it.

And if Qi Lin wants to rely on his own absorption of radiation to charge the shaped energy vortex, if he wants to fill this 200,000 shaped energy vortex, he must sleep in this uranium ore vein every day.

According to absorbing a little energy per hour, it would take him twenty-two years to fill this concentrated energy vortex, and only if the veins of this underground cavern were not exhausted by him, otherwise, he would have to continue digging deep along the direction of the veins......

Looking at the juvenile corpses in one place, Qi Lin had the feeling of "he is really a loser" for the first time in his life......

However, people can't be resurrected after death, and there is no way to come back to life to purify Qi Lin's crystals after being blown up, so Qi Lin can only sigh......

"Well, I wish similar mutated creatures could be found elsewhere......"

Just when Qi Lin raised his feet and wanted to leave this underground cave, he suddenly noticed a trace of strange energy fluctuations - after being promoted to the fourth level, Qi Lin's perception attribute was increased to forty-five points, and his ability to sense radiation sources was increased several times.

"In ...... ...... on top of your head!! ”

Qi Lin raised his head and stared at the dome of this underground cavern, this strange energy fluctuation was coming from the top of the dome through the permafrost.

"Could it be...... The monster's treasure buried here? ”
