Liu Feng's moving footsteps were extremely difficult, and at this time, the originally calm water began to appear ripples, and the green vines that had originally stayed near the manhole cover began to crawl into the sewer, closely following Liu Feng.

They move quickly, swimming in the water like a fish, and this does not hinder their eyesight, which is much freer than Liu Feng.

"Don't touch my butt, be good." Liu Feng felt itching behind his back, thinking it was the little boy who made a prank, he slapped him behind him, but he encountered a thorny antenna.

The tentacles are very slippery. After discovering that it was caught by Liu Feng, it secreted a kind of mucus, which was instantly removed from Liu Feng's water.

"Let’s go faster." Liu Feng is not in love. He held the little boy with one arm and moved fast forward. He could feel that something was coming by his side, not just in the water, but also around. All on the walls.

The two people walked forward for thirty or forty meters before they found the exit that the little boy said.

Liu Feng raised his head and glanced upwards, and found that he had to climb a rusty iron ladder and advance more than 10 meters to reach the position of the exit. The exit was sealed and required a lot of effort to open.

"Did you really climb it last time? It's too high, cough cough!"

Liu Feng carried the little boy on his back. It was normal for him to climb the ladder. He rushed up in three or two steps, and climbed to the middle of the ladder in a few strokes. The vines did not seem to chase in and let Liu Feng relaxed a little.

Seeing that he was about to touch the top of the manhole cover, he suddenly fell from the top of the empty foot.

"Ah!" Liu Feng yelled softly. This iron ladder is very weak. With a little more strength, the rusty part will break instantly. He firmly grasped the edge of the iron ladder to ensure that he did not fall. At the end, hello, hello, end.

Liu Feng was spared. He couldn't imagine how such a small child could climb on his own.

"Brother, you are too heavy. I never fell when I crawled by myself." The little boy didn't realize the situation in front of him, how dangerous it was. He patted Liu Feng on the shoulder, his tone full of pride.

"If you don't want to die, shut your mouth, you will fall into a meatloaf if you fall from here."

Liu Feng's strength is not small, but his two hands also grind out blood, and this time it has caused very serious consequences. It seems that the broken iron ladder is more than that one section, and the following sections have a chain reaction. Fell down.

Liu Feng was horrified to find that he was suspended in the air, and the only thing he could rely on was the two iron rods in his hand.

At this moment, the iron ladder made a creaking sound again, and some rusty iron filings floated on it. Seeing their last place to settle down, they would not be guaranteed.

【Summon Moths】

Liu Feng's hands were sore, he could only summon the moth to use the method of flying to reach the top.

It’s a pity that this place is too narrow. The moth was just called out and got stuck in the sewer pipe. At the same time, the iron rod in Liu Feng's hand fell off, causing him and the little boy to fall heavily on the moth. On the back.

Fortunately, this moth was fat enough and did not continue to fall, but left them in the middle of the sewer.

"What should I do now?" Liu Feng found that the moth could no longer fly. He shook the iron rod in his hand. He couldn't hit the top at all. He could only climb the wall if he wanted to go up.

"Hey!" The sound of vines crawling around came again. They didn't directly attack Liu Feng, but ate away their small living space.

Once the vines grow here, he and this little boy will surely suffocate to death.

"Brother, let's play on the swing." The little boy jumped up suddenly, grabbed a vine, and slid down after a short while, but the jumping action just made him climb more than ten centimeters upward.

"That's right, let's play the swing."

Liu Feng also felt that these vines could be used, but the method he used was much rougher than that of the little boy. In order to prevent those slime skaters from falling off from above, he directly took out the claws left by the black cat. , Poke hard at a vine with feeling.

These vines are painful, and after receiving such a sudden attack, the vine slammed up and threw Liu Feng into the air.

He prodded it with his sharp claws, and finally heard a crisp sound.

"Ding!" This voice made Liu Feng's heart happy, and finally reached the top.

The vines did not intend to let him go, they waved back and forth in the narrow space, trying to tightly tie his body, causing his head to smash against the wall.

But not only did they not hurt Liu Feng, but he used his strength to get to the top.

He concentrated the iron tooth worm on the position of his fist and punched it upward, causing the manhole cover to soar one meter away.

There is an emergency circuit in the mental hospital, and the light inside is much brighter than that in the sewer. Liu Feng took the opportunity to climb up to the edge of the sewer, and with a slight support, he pulled his body out of the dark cave.

"You wait a while, I'll pick you up right away."

Liu Feng yelled to the little boy. He summoned the Hydralisk, which became a long rope after being connected together. The little boy did not notice anything wrong, but thought that the rope would move, so he pulled it directly. Up.

But when he saw the Hydralisk clearly, he was so frightened that he cried. Liu Feng quickly covered his mouth. In this kind of laboratory, wolves would not be recruited, but maybe some zombies would be attracted.

Liu Feng re-covered the manhole cover, blocking the restless vines inside.

"It turns out that the place you were talking about is here. No wonder you can come in so easily." Liu Feng raised his head and looked at the surrounding environment and found that the situation here is not optimistic. It is actually a laundry room.

It is full of patients’ clothes, and some ironing and disinfection equipment. For a well-equipped laboratory, such a room must be isolated from the main area. There is no related password, so it is impossible to enter. go with.

"I don't know if it's here, but let's go in and have a look, I haven't been here yet." The little boy was so adventurous that he actually took Liu Feng and walked outside.

But his heroic behavior was deadly in Liu Feng's eyes. As expected, when he just opened the door of the room, Liu Feng smelled a familiar rancid smell, and the zombies did not all leave.
