However, the eye socket, the joint, the throat, the back of the head, the waist, the eyes, and the underside of the ribs and other parts of the body could not be completely invulnerable, so as long as the bullets were enough to directly destroy it, it would not be difficult for Yun Tu to use his spear.

The reason why he spent so much effort to lure the zombie to the 18th floor and then shoot it was certainly not just to get rid of it.

This body was too weak! The first real battle since his rebirth had actually taken only ten minutes, but due to the pressure and nervousness, Cloud Map was already sweating profusely.

Yes! Watching the ten or so people being killed by the zombies, Yun Tu forced himself not to act because he was waiting for the monster to take shape.

This thing's name was Blood Crystal, and it was a very special kind of energy crystal. It was the first factor in the survival of humans in the apocalypse.

He clearly remembered that in his previous life, he had obtained his first blood crystal in the ninth week after the apocalypse and had finally completed his first evolution.

However, he did not obtain that blood crystal with his own strength. It was obtained after the death of a partner who was in the same boat as him. His teammate, Gui Three, had left for that blood crystal forever.

The reappearance of the past almost made it impossible for Yuntu to control his emotions. It was only when he heard footsteps on the stairs that he finally regained his senses.

Yun Tu should be a hero after killing the first zombie, but he did not want to be one either. Furthermore, he did not intend to return the submachine gun that he got from the special police earlier, so once he achieved his goal, he had no other choice but to escape.

He didn't want to hurt anyone, so it took him a lot of effort to get back to his house. However, he could deal with any zombies that others couldn't handle, and a few ordinary military police couldn't stop him.

Because he didn't want to hurt anyone, after an hour and a half, Yun Tu took the bus back to his residence. After closing the door, Yun Tu smiled. In his previous life, he had finally gotten the upper hand.

In this process, there was a chance for people to experience reconstruction. In his previous life, due to his lack of experience, he only dared to use this chance to heal the old wounds on his legs the second time he advanced. Of course, he wouldn't wait for this opportunity again.

Placing the blood crystal in front of him, he sat cross-legged on one leg and stretched out his old injured left leg. Yun Tu clenched his teeth and used the back of the fire axe to break the small bone in his leg, which had been slightly damaged from his incomplete fracture, with a crack.

The immense pain struck once again, but Yun Tu, who was injured countless times in the apocalypse, was smiling with tears in his eyes!

Swallowing down the blood crystal that he had prepared beforehand, in a split-second, a strong heat was generated in his abdomen, and then spread throughout his body along his limbs and veins. At the same time, his left leg, which had been broken again, also quickly recovered, just like before he was injured.

Perhaps everyone hated the apocalypse. At least, that was what everyone thought at the beginning of the apocalypse. However, after his rebirth, on the first day of the apocalypse, Yun Tu fell in love with it.

If it weren't for the arrival of the apocalypse, Yun Tu, a lame musical scholar who had a criminal record in the police station, might have only been able to live at the bottom of society for the rest of his life. But now, he really saw hope.

After about half an hour or so, the warm current in his body gradually calmed down. The first modification of the human body with the Blood Crystals had been completed.

He was currently feeling very comfortable, as he could easily lift a hundred kilograms of barbell with one arm. Even without using the combat skills he had mastered through countless life and death battles in the apocalypse, ordinary adult men would still not be his match even if they put ten or eight bundles together.

When the human body's attributes exceed a certain threshold, it will ascend to become a level 1 evolved human. Although the evolved human looks the same as the original human, there is actually a fundamental difference in the state of life. The biggest difference is that the original human body can be digitized and detected by the brain.

He pressed his left hand to his chest and closed his eyes. Soon, a string of numbers appeared in his mind:

Name: Cloud Diagram

Level: Level 1

Gender: Male

Occupation: None

Strength: 10

Spirit: 10

Agility: 10

Vision: 10

Hearing: 15

Smell: 10

… ….

Normally, those who did not know what these numbers meant would not understand. However, Yun Tu knew very well that these were the basic data on his body after his promotion.

As for how strong he was, Yun Tu was very clear about it. If he could quantify an ordinary person's ability, then no matter which project he was in, 5 points would be a pretty good number.

Yun Tu smiled when he saw that the six most important parameter words out of the dozens of parameters exceeded 10 and his hearing reached 15. The parameter list that he had obtained was much higher than the ones he had obtained after his evolution from his previous life.

What basic values a person could obtain after evolving would be influenced by several factors. The most important factor was their height, personality, and talent; these factors were difficult to change.

The second most important factor was the way to advance. The most powerful way to evolve was to directly use the mutated black crystal like Cloud Diagram. It was much better than the simple method he had introduced to Greenwing.

Of course, luck was also a factor that couldn't be ignored, but that was completely out of control. God only knew who the apple was that God had bitten.

For example, Yun Tu was a musician, so the sensitivity of his hearing was his natural talent!

… ….

Real rich people usually don't go to the hospital when they are ill. They all have their own private doctors!

Huang Guohao was a rich man, although under normal circumstances, he was not rich enough to hire a private doctor to work as a migrant worker, but as an ambitious and successful man, or a tycoon, he was in the process of matching up with the best of the best in the human race. So today, his wife was sick, so he didn't send her to the hospital, but he still called a familiar doctor at the People's Hospital, Li Huan, to invite him over.

The People's Hospital was as busy as a pot of porridge since around 3 p.m. At 5: 30 in the afternoon, when Doctor Li Huan was the busiest, he received a call from Huang Guohao. Initially, he couldn't get out of the hospital at all, but once he thought of how getting on good relations with a tycoon was more important than taking over a patient, he found an excuse to sneak out of the hospital.

As expected, Huang Guohao's wife's symptoms were exactly the same as the hospital's long line of feverish patients. Huang Guohao told him about the situation in the hospital, and he immediately felt that something was wrong. According to Doctor Li Huan, today's situation seemed to be a major outbreak, and in addition to the blood rain's strange appearance network being already discussed, Huang Guohao, as a businessman, immediately thought of something other than his wife's illness, so he immediately threw away all the stocks in his hands and switched them to medical stocks.

After this matter was done, he did not send his wife to the hospital because with Doctor Li here, as long as the Ministry of Health had a method to control his illness, he would be the first to know about it. Moreover, with his methods, there definitely wouldn't be a situation where he would be unable to purchase a specific medicine, so he was in no hurry to keep his wife at home for treatment.

Although the journey back to the hospital wasn't far, Doctor Li, who originally wanted to take this opportunity to get off work, quickly received a call from the hospital, urging him to return to work. When Doctor Li Huan returned to the hospital, he coincidentally encountered the first case of the hospital's patient's death.

The sudden change scared everyone, including Doctor Li. He only came out of the state of shock after Yuntu took care of the zombies and immediately called Huang Guohao to report the new situation.

At first, Huang Guohao didn't believe him, but after he called another doctor at the People's Hospital to verify his theory, he felt that the situation was getting serious. To be careful, he and his two sons tied his wife, who was in a coma, to the bed.

This time, he was right. Around 8: 30 in the evening, his wife underwent a corpse transformation. After waking up, her mouth had fangs growing out, and from time to time, she would let out strange beast-like cries.

Soon, he personally came out and got to know the whole situation from the police. He personally saw the zombie that was killed by Yuntu.

After looking through all the video information the police had, he knew that the zombies had become stronger because of the constant blood sucking. In the end, the zombies were invulnerable.

What he was most concerned about was not this, but the crippled man in black!

Why was he able to easily take care of the mutated zombie that even the special police officers could not do anything to?

Why did he lure the zombie to the eighteenth floor before killing it?

Why did he cut open the zombie's head after knowing the zombie's weakness?

What did he want to do?

The sensitivity of business made him instinctively feel that the world was about to change.

He didn't have a high education, but he had the courage and efficiency of a tycoon. At 11 PM, he bought over 10 bags of plasma from the blood bank of the People's Hospital, and after strengthening the binding on his wife, he started to carefully feed it with plasma.

Sure enough, everything went as he expected. When he fed his wife the tenth bag of blood, his wife who was originally 1.5 meters tall had grown close to 2 meters in height, then her body began to mutate once again, becoming invulnerable to swords and spears.

The wooden bed frame had already scattered everywhere. The father and son duo used finger-thick ropes to tie up the zombie, but they were still unable to control everything. The strength of the mutated zombie made them feel fear.

"Wealth comes with danger, I think the world is coming to an end soon. It looks like your mom won't be able to be saved, how about we just kill her like that man in black in the hospital and break open her skull to have a look …"

The police medical examiner had not yet concluded whether there was anything special in the cranial cavity of the zombie, but Huang felt instinctively that it was worth studying.

"Middle!"

The two sons actually agreed with their father's opinion without even thinking about it. As for whether their mother still had any consciousness, then they could only chuckle.

Thus, on the night of the first day of the apocalypse, the second mutated zombie's blood crystal was raised by the crazy trio of father and son from the heads of their loved ones …
