The sound was very slight before, and soon became bigger. She was busy looking down the dark stairs. Then she seemed to see something terrible. She gave a cry of surprise, left the stairs and fled in the direction of Suli.

Su Li heard Xu Xuehui's exclamation, immediately looked back, and then saw the stairway leading to the roof. A dark shadow rushed out of the darkness. It was a rat beast.

Immediately after the rat beast, there are dark shadows one after another, all of which are rat beasts.

These rat beasts surfaced before. Instead of climbing the wall, they climbed into the 30th floor of the building along one window. Now they finally appeared on the roof along the upward stairs.

Xu Xuehui saw this group of rats and animals, panicked and fled to Su Li.

Su Li knows it's bad. Xu Xuehui is not the opponent of these rat beasts. As long as she is attacked by a rat beast, it's dangerous.

He had just avoided the attack of the sea iguana and jumped to the other side.

The sea iguana fell a little lower, and Suli immediately understood that it was about to shake its tail.

Sure enough, the sea iguana landed on all fours, and the tail behind him swept over.

Su Li first saw that the sea iguana dragon wanted to shake its tail. He held the iron bar in his right hand and tilted it to the ground. The green tendons on the back of his hand burst out.

The tail of the sea iguana beat heavily on the inclined iron rod.

With a bang, the iron bar was shaking, and Su Li felt the pain in his right arm.

The tail flicking power of the sea iguana is amazing, but it is not enough to bend the iron bar with one blow. Instead, it was bounced back heavily. Su Li approached at the moment of tail flicking, clenched his fist with his left hand, launched the "tooth of gluttony", inserted it into the head of the sea iguana, and then grabbed four deep blood grooves from his head.

The four teeth of gluttony pierced in and cut open all the way down. This is a fatal injury. There is a lot of blood surging out of the four blood grooves.

New information poured out of his mind and he obtained two more spiritual sources. What he obtained became spiritual source 1320.

Su Li succeeded, and Ding Longyun on the other side was no slower than him. He successfully approached the sea iguana, patted the forehead of the Chinese sea iguana with his right hand, and launched "soul eating".

However, he is a level 3 spirit source. If he kills a sea iguana of the same level, he can only harvest one spirit source for each kill. Unlike Su Li, he can harvest two. Now, he still needs five spirit sources to be promoted again, while Su Li still needs seven.

Xu Xuehui rushed to Su Li with a frightened look on her face. Five or six rat beasts had poured out at the entrance of the stairs, scattered in a fan, and rushed towards Xu Xuehui, Su Li and Ding Longyun respectively.

After solving the problem of the sea iguana, Su Li must have moved his right arm, which was numbed by the shock. Feeling the heat flow just obtained from the source of the spirit in his body, he was about to rush towards the rat beast facing him. Suddenly, these scattered rat beasts stopped again. The next moment they made an amazing move, and suddenly turned around and rushed again into the darkness at the entrance of the stairs.

"What's the matter?" Ding Longyun took a steel shovel and just took two steps. He was about to shoot the rat animals. He suddenly found that these rat animals turned around and ran away. He was also stunned.

"Did we scare them away?" Ding Longyun immediately understood and couldn't help laughing.

Su Li's heart jumped, gushed out a feeling of uneasiness, suddenly turned back and looked at the edge of the roof behind him.

The three of them can't scare away this group of rats, so the only possibility is

When Su Li looked back, he saw three more heads on the edge of the roof. It was the lizard head stretched out by the sea iguana, and then three huge sea iguana climbed up.

"Just in time!" Ding Longyun smiled, not surprised but happy. This kind of sea iguana has highly toxic. Although it is difficult to deal with, it has just killed several in a row. Ding Longyun has some experience. Ding Longyun is not afraid. He can be promoted again with only five Lingyuan left. He needs to hunt more monsters to obtain Lingyuan.

As soon as his words fell, the three sea iguanas put on an open frame and were about to rush towards them. Suddenly, there was a "crash" in the rear, and a huge dark shadow rose. Behind the three sea iguanas, a monster as big as a round table jumped up.

This is a giant crab with a gray body and a back shell with a diameter of more than one meter and five meters. Two claws like pliers are huge and nearly two meters long. It suddenly jumped up behind three sea iguanas. A crab claw stretched out and clamped a sea iguana from behind.

The sea iguana gave a scream and twisted its body to struggle. Suddenly, blood was like a fountain. Su Li suddenly opened his eyes. Ding Longyun, who had just returned his indifferent face, showed a look of shock.

The body of the clamped sea iguana giant lizard was cut off, as if it had been beheaded. Su Li and Ding Longyun took a breath of cold air when they saw this scene.

They beat the sea iguana with iron bars and steel shovels. Although they can cause some damage, they can't inflict heavy damage. The hardness of the skin and flesh of the sea iguana can be imagined. Now, they were caught by the claws of the giant crab. How sharp and powerful are the claws?

In the shock of the three people, the two claws of the giant crab waved out, and the powerful sea iguana seemed vulnerable to its attack. One sea iguana was directly swept by the pliers and tumbled down from the roof. The other sea iguana was gripped by its tail, struggled desperately, broke its tail to survive, rushed suddenly and took the initiative to rush out from the edge of the roof, Fell and disappeared.

The giant crab is obviously not interested in the sea iguana. Its real purpose is to attack the three Suli. It only attacks the sea iguana to clear the obstacles in front of it. Then it swipes its legs on both sides and quickly comes towards the three.

"Get back!" Su Li shouted loudly. Seeing that the monster was so terrible, he knew that they could not deal with it. If they fought hard, they would probably cause casualties.

As soon as he grabbed Xu Xuehui's arm, he rushed to the head-on stairway.

Ding Longyun didn't dare to stay and face the monster alone. He rushed to the entrance of the stairs and shouted, "I know, those mice were scared away by it, not by us!"

Suli thought you knew? Holding Xu Xuehui, he rushed into the stairwell facing him. Ding Longyun also followed him. The giant crab bumped up a little later than him and hit the stairwell with a loud noise.

"Hey, it's dangerous. It's too big to get in." Ding Longyun breathed a sigh of relief and immediately became happy. He stood at the entrance of the stairs, clenched the steel shovel with both hands and patted the giant crab blocking the door.
