From beginning to end, Luo Chen looked at Professor Mu's tragic situation as if he had heard of them, and did not have the slightest intention of going to rescue them. With the current situation, even if they are saved, it will only be equivalent to adding two burdens.

Zhao Youyou cut a 'Rat Corpse Brother' in two, blood sprinkled on her, and the white coat was already blood-red, but she had no time to care about it at this time, she glanced at the two people who were devoured by the 'Rat Corpse Brother', and asked Luo Chen, "What now?" ”

At this time, even if they blocked the exit of the corridor, it didn't have the slightest effect, and the number of 'Rat Corpse Brothers' who turned up from the edge of the rooftop continued to increase, except for a small number of people who were attracted by Professor Mu Su Shan, and the rest all rushed towards them.

Luo Chen didn't plan to continue to block here, and was about to tell Zhao Youyou to retreat, when his pupils suddenly shrank, and he shouted: "Get out of the way!" ”

A 'rat corpse' the size of a bull and covered with white bones rushed fiercely from the corridor, and the corpses piled up at the entrance of the corridor were scattered in all directions.

This large 'Rat Corpse Brother' is definitely the top existence of its kind, with a huge body covered with white armor and bone spurs, limbs as thick as a tiger lion, a huge head, and a mouth more hideous than a crocodile, which has completely detached itself from the image of a mouse.

After the large 'Rat Corpse Brother' rushed to the rooftop, his momentum was unabated, and he pounced on Luo Chen in a rage.

The swift movement made even their distant Australian relatives marvel.

Zhao Youyou was reminded by Luo Chen before, and dodged to the side and back in time.

Therefore, the trajectory of the collision of this large 'Rat Corpse Brother' passed by her.

A hint of coldness flashed in her eyes, her silver teeth clenched, her left hand held the handle of the knife back, the blade was lifted up, from the bottom up, and slashed the 'Rat Corpse Brother' sideways.

Money!!

Zhao Youyou's left hand holding the knife was shocked and numb.

The blade slashed at the large 'Rat Corpse Brother', but it was blocked by the white bone armor, and only a few bone fragments were broken.

"It's so hard!"

Zhao Youyou was shocked in his heart, but he didn't recklessly, and retreated with the help of reaction.

However, Zhao Youyou's knife didn't use the strongest explosive power of his body in a hurry, otherwise he would definitely not even be able to break through the white bone armor.

This large 'Rat Corpse Brother' was actually somewhat affected by the impact of this knife, and the speed of the collision was a little sluggish.

Luo Chen reacted quickly, facing the monster that was rushing head-on, he did not retreat but advanced, and the monster's movements seemed to slow down in his eyes.

The Mo knife stabbed out like thunder.

This knife is very accurate, and it is extremely fast, and even monsters can't react.

The tip of the knife pierced through the roaring and hideous mouth of the large 'Rat Corpse Brother', and under the effect of Luo Chen's explosive power and the opponent's fierce impact, the one-meter-two-long blade penetrated into the opponent's fragile body.

The monster struggled desperately, its massive body tumbling.

In this case, those trumpets of the 'Rat Corpse Brothers' still frantically pounced on and devoured Luo Chen. Seeing this, Zhao Youyou hurriedly dodged and came to Luo Chen's side, the blade was as fast as lightning, and he simply divided the corpses of those 'rat corpse brothers'.

Luo Chen kicked away a 'Rat Corpse Brother' who pounced on him, clenched the long handle of the Mo Knife with both hands, and flipped it back and forth vigorously, causing the blade left in the body of the large 'Rat Corpse Brother' to stir wildly.

As Luo Chen's damage increased, the monster gradually stopped struggling.

The word count jumps in the lower right corner of his eye, indicating that he has gained 20 experience points again.

Luo Chen pulled back the Mo knife vigorously and looked at Zhao Youyou: "Are you okay?" ”

He asked about the knife between Zhao Youyou and the large 'Rat Corpse Brother' just now.

Zhao Youyou shook his head lightly, indicating that it was okay.

The pretty little face was tense, and the cheeks were stained with blood at some point, intertwined with the sweat flowing on the face. Although she didn't speak, the golden pupils revealed the heaviness in her heart.

The two simply retreated from the entrance of the stairs, back to back.

Luo Chen is now a little glad that he used a booster on Zhao Youyou last night, otherwise he would probably have to face this terrible situation alone now.

Without their obstruction, the 'rat corpse brothers' at the entrance of the building rushed out.

On the rooftop, there were 'rat corpse brothers' all over the place at this time, and what was worse was that dozens of large 'rat corpse brothers' rushed out of the corridor exit, and there were eight or nine of them the size of bulls.

The center of this group of 'rat corpse brothers' is Luo Chen and Zhao Youyou, who have no way out.

At this time, they surrounded Luo Chen and the others to death, but instead stopped their frantic attacks. But under the gaze of countless pairs of brutal and bloodthirsty scarlet eyes, and the incessant sharp screams, the pressure on Luo Chen and Zhao Youyou continued to increase.

If you are an ordinary person, under this kind of pressure, I am afraid that you will not be able to help but collapse and commit suicide first.

Zhao Youyou adjusted his breathing, and his voice was suppressed: "What now?" ”

Luo Chen's body was steaming, forcing his brain to stay calm, he had two more strengthenings than Zhao Youyou, and his state was obviously better than Zhao Youyou.

"Rest assured, it's not a desperate situation yet! You didn't find out? There are no rats climbing up below, which means that you just need to solve all these things in front of you! ”

Zhao Youyou was speechless, Luo Chen's words really made her not know how to refute.

At this time, they were trapped on the rooftop, and there was no way to run, except to solve all these on the rooftop, and there seemed to be no other way to go.

The problem is that there are at least three or four hundred of them on the balcony of the 'Rat Corpse Brother', and in addition to the large number of ordinary ones, the attack power is quite okay. But there were at least thirty or so pigs in size, and there were eight or nine of the bulls that Luo Chen had killed just now.

The pressure they are facing now is not as easy as waiting for a rabbit at the top of the stairs just now. Because they only need to face one direction together, and there is also the geographical advantage that the entrance of the building is too small to limit the numerical advantage of the 'Rat Corpse Brother'.

And now, they have no other support behind them except each other, and the pressure is at least 10 times greater. Whether he can escape or not is unknown, and even thinking that all these 'rat corpse brothers' in front of him will be slaughtered, Luo Chen is too confident.

However, Luo Chen's words finally reduced the panic in Zhao Youyou's heart a lot.

Luo Chen is not confident, he really only has the only way to go hard.

He himself had not expected this situation.

Originally, I thought that I could spend the remaining half a day in peace and peace, and successfully end this trial mission, but these ghost things suddenly appeared without warning, but they still came at themselves, and they didn't seem to appear in the original book?

He couldn't help but suspect that the system saw that he was too relaxed and deliberately tossed himself?

Sure enough, the original things can only be referenced, not all believed.

Luo Chen saw that the 'Rat Corpse Brothers' did not rush to attack them, but instead devoured the corpses of those same kind that he had just killed.

He turned his head sideways to Zhao Youyou and whispered: "Take advantage of now, if you use another booster, the pain of the second use will not be as strong as the first time, and it will not affect your mobility, but it can increase your chances of survival." ”

The most important thing is that the stronger Zhao Youyou, the less pressure he faces.

He himself made the decision to use the 'God's Gene' when necessary.

After all, even if there is trouble, you have to live before you have a chance to think about it.

"Good!"

Zhao Youyou almost didn't have to think about it, and agreed with Luo Chen's proposal.

Without hesitation, she stared at the 'Rat Corpse Brothers' vigilantly, slowly crouched down, put the machete on the ground with her left hand, reached into the backpack she was carrying behind her, took out an alloy box from it, and after opening it, she took out the golden syringe.

She didn't take out the rest of the inhibitor in the box, she just closed the alloy box and placed it on the ground, the box was strong enough to ensure that it would not be damaged.

Chi Ze changed, Zhao Youyou quickly tore off the sports vest, revealing snow-white skin, the syringe was directly pierced into the chest, and then the medicine was injected into the body.

"Squeak!" "Squeak!" "Squeak~squeak~"

Zhao Youyou's behavior was like a fuse, and the 'Rat Corpse Brothers' were ignited wildly again, and in all directions, dozens of 'Rat Corpse Brothers' pounced at the same time.
