Although she also pointed out that her inspiration came from novels when she said that there might be crystal cores in the zombies' brains, Jiang Tianyan and the others more or less took Du Yuanxiang's words to heart because she mentioned that crystal cores could enhance superpowers.

This made Jiang Tianyan and his teammates subconsciously look for crystal cores after killing stronger zombies.

Wen Yubai was in Jiang Tianyan's team in his previous life, so he knew that Jiang Tianyan had really found the crystal core in the head of a first-level zombie.

In the previous life, because Jiang Tianyan almost controlled this team, all the crystal cores harvested along the way fell into his hands. Therefore, they were also the first to know how to use crystal cores for upgrades.

Therefore, in his previous life, Jiang Tianyan and his teammates gradually stood out after the end of the world and became the team with the highest level of superpowers. Jiang Tianyan even became the number one master in the end of the world.

In her previous life, Wen Yubai was never able to enter the core of this team due to Xiao Tianhui's strong rejection, so she never knew about the crystal core helping with cultivation.

Even if the system told her about the crystal cores in the zombies' heads, she kept it and it was also an upgrade for the system.

It was not until two months after the end of the world that the official researched an exact method of using crystal cores to upgrade superpowers. After it was fully disclosed, Wen Yubai knew that crystal cores could be easily used for cultivation.

This was also the reason why Wen Yubai had been suspicious of the system in the year after she obtained it, because this suspicion caused both she and the system to waste time.

It was not until later that Wen Yubai found out from the side that there was a main god above the system, and the main god had set many restrictions for it. There were some things the system really didn't know, and even if it knew, it couldn't say it.

After Du Yuanxiang joined Jiang Tianyan's team in this life, Wen Yubai spent most of his time in military vehicles and rarely saw Du Yuanxiang and the troublemaker Jin Xiaoxia.

So she was sure that these two women were hardly influenced by her in this life. Du Yuanxiang, whose fate had not changed much in her previous life and this life, would probably still approach Jiang Tianyan by providing information in order to please him and give him this advice again.

Therefore, Wen Yubai didn't find it strange at all when he saw Jiang Tianyan digging out the crystal core from the zombie's forehead.

"Host, there are still five level one zombies whose crystal cores have not been taken." The system said regretfully.

"If you want to reveal your identity, just go and get it." Wen Yubai said unmoved.

The system stopped talking.

In fact, the system didn't know, and Wen Yubai was still a little heartbroken, because no one else knew about the crystal core, and he couldn't tell anyone. Jiang Tianyan and his men might take advantage of helping the army clean up the zombies to get the other five crystal cores.

Wen Yubai, who was out of sight and out of mind, went to look at other people. The battle was over and everyone, including Wen Yuxian, turned around and walked into the hotel.

Thinking that the five crystal cores would fall into Jiang Tianyan's hands again, Wen Yubai was somewhat depressed and was about to withdraw his mental power when he suddenly "saw" a soldier walk up to Captain Pei and say something to him.

After listening to the soldier's report, Captain Pei subconsciously glanced at Jiang Tianyan, then strode towards the corpse of the first-level zombie, stabbed the zombie's forehead with a long knife, and then pried it hard...

Because the distance was too far and Captain Pei's movements were too fast, Wen Yubai couldn't see clearly whether he had pried anything out, but judging from his gestures, he was using the wind to blow something from the air into his hands.

"Ah, Captain Pei actually also knows that there is a crystal core on the forehead of the first-level zombie." The system was shocked and said, "But when I bound you, the host, in my previous life, the army didn't know that there was a crystal core in the zombie's head."

Wen Yubai said helplessly about the crappy observation of this crappy system: "How can the previous life be the same as this life? In this life, the entire army has always been in the hands of Captain Pei. Didn't you see that he did this after a soldier said something to Captain Pei? It should be that the soldiers saw Jiang Tianyan digging the crystal core and reported it to Captain Pei. How could Captain Pei, who is so capable, not take it seriously?"

Wen Yubai was thinking about reminding Captain Pei about this matter when she had the chance, so as to prevent most of the zombie crystal cores on the battlefield from falling into Jiang Tianyan's hands like in her previous life. Unexpectedly, he didn't need her to remind him at all.

However, this episode made her feel better all of a sudden. With Captain Pei's ability, after he knew about this, Jiang Tianyan and others would never be able to take advantage of him again.

When Wen Yuxian returned to the room, she had already cleaned herself up. Although she was a little tired, she was still excited.

"Captain Pei told us to be prepared and evacuate here in half an hour," said Wen Yubai.

They killed so many zombies that even Wen Yubai on the eighth floor could smell the blood.

With Captain Pei and his men's common sense, they must have known that the smell of blood might attract other predators, so they ignored the fact that they had just fought and were in a hurry to leave.

In the next few days, the zombies seemed to be very active. Not only did they encounter groups of zombies during the day, but they were surrounded by zombies every night. However, the scale of the attacks was not as large as that day at the resort hotel, but the number of level one zombies mixed in gradually increased.

Therefore, it was easy for the army and the survivors to cope with it. No one was killed or injured, and their combat effectiveness increased rapidly.

Although Wen Yubai practiced gold-related supernatural powers openly and mental supernatural powers secretly, his advancement in cultivation was no slower than that of others.

Because everyone unanimously disagreed with her joining the zombie-killing team, she was either trapped in the car or stayed in the room "watching" others kill zombies. She was "watching" others waste points and harvest first-level zombie crystal cores with envy and jealousy. It was really a torture.

Just when she couldn't stand it anymore, she counted that she had been injured for six or seven days. It wouldn't be shocking to say that her injury was no longer serious. At most, it would make people think that her recovery ability was super strong. So she drank the healing potion early in the morning and prepared to announce that her injury was no longer serious.

Who knew that an extremely cold wave was about to arrive. Captain Pei ordered everyone to speed up their journey and run directly into any zombies they saw along the way. Wen Yubai had no chance to get out of the car to kill the zombies.

This day is the fourteenth day of the apocalypse. Captain Pei and his men received a warning from their superiors in the morning, knowing that a cold wave would arrive tonight.

In fact, there is no need for warnings from superiors. The sudden rise in temperature this morning is enough to make people alert.

Because there were no accommodation facilities in the wild that would allow everyone to hide in buildings and survive the cold wave, Captain Pei and his men discussed with several captains and decided to charge into a nearby city, clear out a community near the suburbs, and resettle hundreds of thousands of people there.

It was a little after three in the afternoon, and the staff had not yet been fully resettled when the sky, which had been sunny all day, suddenly darkened, and gusts of wind blew up, followed by heavy rain.

Then, in less than two minutes, everyone could clearly feel gusts of cold wind blowing in, and the temperature was dropping rapidly.

Although everyone had put on their thickest winter clothes, they still couldn't help shivering.
