The four of them walked very carefully, Yu Hao walked in front with a shield, Li Yixiao held the long sword and broke the back, and Xu Yun and Luo Xiao were in the middle of the two.

Before leaving, Luo Xiao made most of the remaining materials into runes and wrote them on his body, the materials were limited, he could only temporarily strengthen his arms and legs, before the energy of the runes was exhausted, his legs and arms could burst out about four times the strength of ordinary people, both speed and destructive power could be greatly improved.

According to Luo Xiao, the senior brothers and sisters of their academy have almost carved the inscriptions into their own flesh and even bones, they are still flesh and blood, but they can compare to the gods by relying on the power of the inscriptions, and some runes can even run endlessly.

Among the four people, Xu Yun is the least combative, but she is the most effective among the four.

"Xu Yun, what methods do the seniors of your academy use to strengthen their own strength? I once met a sophomore in medical school on the school bus, and she was so fast that even I wasn't sure I could keep up with her now. Yu Hao said relying on the communication function of the school emblem.

They are a group, although they can divide part of their strength to protect non-combatants like Xu Yun and Cheng Jing, but this is only in a relatively safe situation, if they encounter a strong enemy and everyone is too busy to take care of themselves, then they must rely on their own strength to protect themselves.

"This involves more advanced medical technology," Xu Yun said, "It is more similar to your genetic modification technology, we change the microstructure of our body through surgery to give us super strength, speed and physique, but in terms of potential, it is still weak, and it should be barely okay if we protect ourselves." ”

"That's not bad," Yu Hao said, "I've checked, things of the same grade can be traded with each other, and when my ability is enough, I will definitely get you a good bloodline potion." ”

"Then I'll remember!" Xu Yun said with a smile, the power of the bloodline has always been considered one of the strongest strengthenings.

"I said Yu Hao, you kid can't favor one over the other!" Luo Xiao said dissatisfied.

"Hahaha, don't worry, you'll be indispensable when the time comes!" As the first few partners, Yu Hao will not be stingy with them.

Each of them has an extraordinary physique, and they have already traveled dozens of kilometers in a few hours, but then they have to face a very serious problem, because it is starting to get dark!

The fog is not born naturally, so it does not disappear because the temperature drops when it gets dark, and the original visibility is already very low, and in the night, they will simply become a group of blind people who can't reach out and can't see their fingers.

"Everyone be careful, once you find any trouble, you must immediately let everyone know in the communication!" Yu Hao held the shield tightly in his hand, he must definitely find a way to get a weapon to take advantage of when he goes back, although this shield is extremely strong, but after all, it is only a defensive weapon, and it is not suitable for him.

It seems that because of the help of the night, the attacks of those monsters have become more and more unscrupulous, in just two hours, they have been attacked by five or six waves, although the monsters that attacked them are not strong, at most they are only G-level, but they still make Li Yixiao and Luo Xiao suffer some minor injuries.

However, because they had already completed part of the second mission, those extra kills became extra credits for their accounts, Yu Hao got 350, and everyone else also received additional points ranging from one point to another.

Xu Yun's performance, which made Yu Hao's eyes shine the most, she is not a "nurse" character who is powerless and can only treat the wounded, her scalpel is wielded in her hands in a kaleidoscopic way, and several monsters are killed by her alone, as for how much effort has been put in behind it, only she knows.

"If you're not mistaken, you'll only be rewarded with credits for killing creatures that are less than two levels below your level." Yu Hao seems to know some of the principal's rules again. But think about it, there should be similar restrictions, otherwise those low-level creatures are just walking credits, and they can't bring any challenges to students at all, so some exams don't make much sense.

Yu Hao even boldly deduced that not all things killed can be credited, because although it is the exam world, the humans here also have a biological level, and if you can get credit rewards for killing, then the exam world will definitely be chaotic.

"Wait a minute!" Yu Hao, who was walking in the front, suddenly stopped, "Did you hear any movement?" ”

Everyone shook their heads, but Yu Hao's senses were more acute to any of them, and they didn't doubt Yu Hao's judgment.

After about ten seconds, everyone's faces changed, and they heard a very dull sound coming from a distance.

Luo Xiao lay on the ground and pressed his ears tightly to the ground, and he heard a loud vibration.

"Something's coming, and it's huge! Definitely not human! ”

"Whew!" A strong gust of air rushed to their faces, and they actually blew away all the dense fog tens of meters in front of them, and then in the dim moonlight, they actually found that it was a huge group of monsters!

Sulfuric acid spiders, dragon flies, thorn insects...... This is what they have encountered along the way, and from this number, there are at least hundreds or even more.

"How so!" They had traveled more than 200 kilometers, and it was the first time they had seen such a huge group of monsters, there were only four of them, and they were absolutely shattered in the face of the tide-like monsters.

"Get up to that tower!" Yu Hao pointed to a building next to him and said, this is the only place in the neighborhood where he can hide, he feels as if this group of rampaging monsters is not coming at them, it seems to be ...... Like you're running for your life?

"No, it's too late!" They ran frantically to the side, but the monsters were so fast that they were overwhelmed by the monsters before they could climb the tower.

"You go up first, I'll stop them for a while!" Yu Hao stopped suddenly, this trick can't be used if it doesn't matter what's critical, but now it's in that situation.

"Are you crazy? It's a group, not one or two, you can't stop it! ”

"Hurry up, we'll all die if we waste any more time!"

A powerful aura erupted from Yu Hao's body in an instant, and even a ball of aura visible to the naked eye burned on his body, this was the first actual battle after he learned the battle qi burst!
