In fact, Liu Chi learns things quite quickly, he just didn't understand what Ding Chen meant just now. After the www.biquge.info failed once, he remembered the last time he was a pioneer with Ding Chen, and he had seen Ding Chen and Zheng Yu use this method to cooperate with the watchtower.

After having the actual frame of reference, Liu Chi felt much better, at least he was no longer confused. So when the two of them cooperated in actual combat for the second time, Ding Chen was easily sent to the ladder on the outer wall.

When Ding Chen's body was in the air and he grabbed the iron ladder hanging in mid-air with both hands, there was a tooth-sore creaking sound on the ladder, and at the same time, Ding Chen felt that the hand that grabbed the ladder sank down, and he couldn't help but be shocked.

Now his action is actually very risky, if he just doesn't catch it and falls, it's fine, if the whole ladder also falls, then Ding Chen will be hit by the ladder in addition to falling, and the consequences will be difficult to say.

Fortunately, Ding Chen's character is good, and the fire escape finally held up and did not fall off the wall as Ding Chen feared. Ding Chen breathed a sigh of relief and climbed up the ladder.

Liu Chi watched Ding Chen climb higher and higher along the ladder, and shouted, "What should I do?" ”

Ding Chen glanced down at him, "You want to come up too?" ”

"Of course." Liu Chi shouted, "I don't want to stay here alone. ”

Ding Chen thought for a while, and also felt that it was not righteous to leave Liu Chi downstairs alone, so he shouted to him: "This ladder can't support two people, you wait for me to go up and then pull you up." ”

Liu Chi felt a little strange, thinking to himself, how can you get me up when you go up? Unexpectedly, after Ding Chen climbed to the top of the building, he actually took out a bundle of rope from his backpack and put it down.

Liu Chi grabbed the rope and found that Ding Chen had tied a loop to the front end of the rope. According to Ding Chen's instructions, he turned the rope loop over and put it on his two legs, then held the rope with both hands, propped his legs on the wall, and asked Ding Chen to pull him up.

The exterior of this building is no different from the other buildings, and the roof is the same. Winter here in the Old City is just over a month, and the snow is naturally not very heavy, so the roofs are usually flat, and these buildings are no exception.

Liu Chi didn't quite understand Ding Chen's purpose of taking him to the top of the building, so he asked tentatively, "Are we going to dig a hole from the roof?" ”

Ding Chen glanced at him deeply, nodded and exclaimed, "Good idea." ”

Of course, he wouldn't really go down from the roof of the house as Liu Chi guessed. It doesn't make sense that the people who built the house would cut corners on the roof of the building by inlaying so much steel bar.

He walked around the roof of the building and soon found a steel plate half a meter square fastened to the roof. Looking at this rusty steel plate, Liu Chi asked curiously, "What is this?" ”

"A lid." Ding Chen said.

He put down his backpack and pulled a hand-held cutter out of it. This is a maintenance tool on Ye Tianlong's maintenance car, which is powered by a rechargeable battery block, so it can be easily moved.

Ding Chen took out the saber first, sled and knocked on the steel plate, and tinkered for a long time, then selected a position, opened the cutting machine and pressed it.

It was only at this time that Liu Chi discovered how thick this steel plate was. Ding Chen used up the first grinding wheel, but he couldn't cut a large enough gap in the steel plate, so he had to replace it with another one. To be honest, this consumption rate of consumables simply made Ding Chen vomit blood.

This time it finally succeeded, as the load of the cutter in his hand became significantly lighter, Ding Chen carefully lifted the cutter, put it aside, and then took out a hammer from his backpack and smashed it the triangular notch cut out.

The sound of the homogeneous steel plate that was nearly five centimeters thick was a little dull when it was hit, and there was no obvious deformation, so Ding Chen waved the hammer a few more times, and when he hit it for the last time, something flew out, and there was no expected impact sound.

The two looked at each other, Liu Chi looked at the bare hammer handle in Ding Chen's hand, and said dumbfounded: "The hammer head flew." ”

"I know." Ding Chen stood up and looked around, walked to the side of the building, looked down, and said, "It's falling." ”

"What then?" Liu Chi asked stupidly.

"Go down and pick it up." Ding Chen said as a matter of course.

Liu Chi stretched out his head to look down and suggested to Ding Chen, "Actually, the butt of the gun can also be used as a hammer." ”

"That's on the stock of your gun." Ding Chen immediately said without hesitation.

So Liu Chi gave in and prepared to go down to pick up the hammer, he was more reluctant to go to the grass than to go to the grass.

In fact, Ding Chen was not reluctant to use the butt of the gun, but there were not many hammers in the apartment, and he couldn't afford to throw them. Since you have to look for it sooner or later, of course, you can find it back sooner and worry about it, and you may be able to use it after entering the building.

This time, there was no need to go up the stairs, Ding Chen directly took a rope to go down Liu Chi from the top of the building, and then stayed on the edge of the building to wait for him.

Liu Chi was almost bitten by a snake in the morning, so he acted very carefully, fiddling carefully in the grass with a gun, and refused to walk quickly.

Ding Chen could only judge the direction of the hammer head by the angle of the hammer, and there were weeds downstairs, and he couldn't see the hammer head, so he had to watch Liu Chi slowly hunt for treasure.

When he was bored, his eyelids suddenly jumped, turned over and squatted on the edge of the building with his gun raised, and shouted, "Liu Chi." ”

Liu Chi's attention was on his feet, he was startled by Ding Chen's voice, looked up at him and asked, "What's wrong?" ”

"Come back." Ding Chen raised his gun and aimed at a certain target, and shouted loudly: "Hurry up, find a place to hide." ”

No matter how dull Liu Chi was, when he saw Ding Chen's appearance, he knew what he had discovered, and this time he was not afraid of the things in the grass, so he ran back to the side of the building with a smoke, and looked around, unfortunately there was no particularly strong obstacle to use as cover, so he had to squat down with a gun and shouted to Ding Chen: "Then what should I do?" ”

Ding Chen ignored him, stared closely at the pile of scattered construction waste in the grass in the distance, and shouted, "Come out, or I'll shoot." He exclaimed, "I don't care about wasting bullets. ”

The man behind the pile of stones hesitated for a moment, and also shouted, "What should you do if you shoot when I come out?" ”

"Then it looks like we're going to have to wait until it's dark." Ding Chen shouted. But then he suddenly noticed something farther away, and flashed. Startled, he slammed to the ground and heard a gunshot. Ding Chen could almost feel the air flow from the bullets flying past him.

Ding Chen flipped over on the edge of the roof with his rifle, moved out of a distance, and then poked the gun out of the roof and fired a shot at the reflective place just now.

It is very rare for a group of two to cooperate with a tacit understanding of the scavengers, and even fewer scavengers who have been trained as snipers, in the direction where the flash came from just now, the position that can hit this trajectory is at least three hundred meters away from Ding Chen, it is obvious that he now has a very clever enemy, such a combination is considered the top even among the scavengers, and this time he won the jackpot.

Taking advantage of his dodge, the person he found just now also quickly rushed out from behind the rocks, Liu Chi immediately shot, but he completely misjudged the trajectory of the person's movements, so the bullet did not pose a threat to the person at all, and he could only watch the person rush to the nearby building.

But at this time, Ding Chen changed his position again, and he had already raised his gun to aim at this person, but at the moment when he pulled the trigger, a thought suddenly flashed in his heart, and he felt that this person's tactical movements were very familiar.

So at the last moment, his hand was raised a little, and the bullet went over the man's head and hit the building in front of him.

That person obviously didn't expect Ding Chen to hit so accurately, and in surprise, the soles of his feet slipped, and he had already fallen to the ground with his head and back of his feet, and at the same time completed the preparation of turning around and raising his gun. At this time, the sniper who was hiding in the distance also fired another shot, and it was obvious that the first shot of Ding Chen's counterattack did not hit.

But at this time, Ding Chen had already re-hidden, so the sniper's second shot also missed. The first round between the two sides ended in a draw.
