As for how powerful he was, Wen Yubai only knew that he had two killer moves.

One of her ultimate moves is mental piercing, just like she used her mental power to attack the enemy's brain before. However, even though she was in the late fourth level, she could only cause the enemy's brain to become momentarily chaotic and the movements to stop for a few seconds.

But it is said that a fifth-level psychic can use mind piercing to directly damage the enemy's brain, causing the enemy to fall to the ground and unable to get up.

Another sure-kill move is teleportation, about which Wen Yubai has no clue, because she has never seen it with her own eyes and cannot imagine it. However, the lethality of teleportation is also very terrifying, making it difficult for the enemy to defend against it.

Originally, Wen Yubai's dual-system abilities had reached the fourth-level late stage yesterday, but because the environment she was in was not safe enough, she was afraid of something going wrong so she did not dare to force the advancement.

With Pei Shibin protecting her tonight, she vowed to advance to the next level, otherwise she would have no chance of winning against the level five monster tomorrow.

In her previous life, Wen Yubai was already a level five gold-type ability user before she died, so there was no barrier for her to advance to level six gold-type ability.

Like now, after she drank the fine pure spiritual water, she concentrated on cultivating her mental power, but her gold power was upgraded unknowingly.

However, the spiritual ability required her to explore step by step and break through the level. Knowing that someone was protecting her, Wen Yubai was not impatient and tried again and again, and finally advanced.

During the practice, Wen Yubai also vaguely felt that he had spent a very long time.

When she finally consolidated her cultivation, she stopped practicing, opened her eyes, and looked at the time on her bracelet. It would be dawn in half an hour. Her practice took more than three hours.

"System, nothing happened this night, right? What was Brother Pei doing when I was practicing?" Wen Yubai asked the system.

"Major Pei stayed in the living room all night. He only slept for two hours and then got up." said the system.

"Is there something wrong?" Wen Yubai asked as he walked out of his room.

In fact, there was no need for the system to answer. Wen Yubai had already seen Pei Shibin staring at the surveillance screen, and on the screen, just below the entrance of their cave, there were five or six strange beasts wandering around.

There was also a strange beast that looked somewhat like a monkey that climbed up into their cave, dismantled the protective metal nets that Wen Yubai had set up at the three entrances, and was attacking their safe house.

Only a level five monster could remove her metal net, so their guess was correct, and the monster that appeared today was a level five monster.

Although Wen Yubai walked silently, Pei Shibin turned around as soon as she walked out of the room.

When he saw her, the man's slightly frowned brows suddenly relaxed and joy filled his eyes.

"Awake?" Pei Shibin asked.

When Wen Yubai walked over, he pulled her to sit on his lap.

"Well, it's so exciting so early in the morning." Wen Yubai said, her attention was on the strange beast on the screen.

She still remembered that early yesterday morning, she felt that she was facing a hell-level development. In comparison, today was the real hell-level development.

"It's okay. I'll go out and deal with this one first. It will consume a lot of energy to let it attack the safe house like this." Pei Shibin said.

It is said that the energy box of the high-level safe house can last for ten days or eight days even if the defense system is turned on, and it can last for two months under normal consumption. But at 20,000 gold coins per energy box, who would be willing to waste it like this?

Although the person in his arms was a little absent-minded, Pei Shibin couldn't help but kiss her several times before letting her go with regret. Although the two had made their relationship clear, this was not the right time to be affectionate.

Wen Yubai was practicing before, and he was afraid of alarming her, so he only monitored this monkey-like beast and did not take any action. Now that she has come out, he will naturally not let this level five beast go.

Pei Shibin's wind ability was only at the middle stage of level four, but from his tone it seemed like a small matter, so Wen Yubai didn't say anything more.

He was not the kind of person who was so arrogant that he didn't know his limits. When he had cultivated his internal energy to the sixth level, his strength was equivalent to that of a fifth-level psychic. Now his internal energy was already at the seventh level, and even if he couldn't fully exert the strength of the seventh level, it would still make him stronger than yesterday.

Wen Yubai's estimation was correct. Pei Shibin, holding the big knife she had tempered before, easily killed the level 5 monster in the narrow cave.

A weapon tempered by a late-stage fourth-level gold-type superpower would be as difficult to kill a fifth-level beast as cutting meat with a blunt knife. But Wen Yubai looked at Pei Shibin's movements, as if he was holding an extremely sharp sword.

Wen Yubai was so surprised that her mouth could hardly close. Pei Shibin's skills were almost equal to the sixth-level psychic she had seen in her previous life. She didn't expect that the Pei family's internal skills were so powerful.

Pei Shibin's appearance stimulated the strange beast under the cave. When he was killing the monkey-like beast, a level five strange beast that was good at climbing walls rushed into the cave.

The narrow cave entrance restricted the movement of the strange beast, so it was simply seeking its death, especially since this strange beast had big, Caslan eyes.

Because the narrow space of the cave had been occupied by Pei Shibin and the monkey-like beast, Wen Yubai had to stand at the door of the safe house. The level 5 beast, Kazilan, who had just squeezed in, didn't look directly at her, so she threw two throwing knives at her.

The flying knife went straight into the eye of the level 5 monster. Although it was not fatal due to lack of force, it still knocked the monster out of the cave and it fell down.

The injured alien beast fell into the pile of alien beasts, and needless to say, it was quickly eaten by the alien beasts.

However, this battle gave Wen Yubai an inspiration: "Brother Pei, we can dig one or two more caves. When there are too many strange beasts under the caves, we can lure them in and kill them separately."

After hearing Wen Yubai's suggestion, Pei Shibin also thought it was a good idea. After selling the monkey-like beast to the bracelet system, the two walked to the entrance of the cave and looked down.

At this time, there were only three level five alien beasts below the cave. When they saw the two people, they jumped excitedly and wanted to attack them. Unfortunately, the cliff of more than 20 meters made their one or two meter long legs look like short legs. The alien beasts that could neither climb nor fly were really helpless.

"There are only three level five alien beasts under the cave now. We two can easily deal with them. Let's just kill them first, in case more alien beasts come later. There will be too many of them." Pei Shibin said.

Both of them advanced at night. The three level five monsters did not pose a fatal threat to them. Instead, they could be used to hone their skills.

Pei Shibin still held the long sword, but Wen Yubai had tempered it for him again, so it would be easier for him to kill the level five monster.

Wen Yubai chose a spear. She did not have Pei Shibin's erratic skills, so she could only use the spear to distance herself from the monster.

"I will first hold back the two level five monsters on the left, and you will quickly deal with the monster on the right." Pei Shibin said.

Wen Yubai made an OK gesture to him.
