After about 5 minutes of walking, Derek finally gave the order to "get to the ground".

Stopping, Xu Renjie raised his eyebrows and glanced at the top of the well, and two narrow white lights shot straight down from the aperture of the top cover, falling on the ground to form two spots, bringing some vitality to this dead and silent well.

As Derek previously mentioned, the outside of the roof should be a construction site surrounded by gelatinized panels. So it should be safe in theory.

But through the unexpected incident at the bottom of the right well, Lao Xu is skeptical of Derek's description.

Holding the knife in his hand, Xu Renji handed Lei Tong a color and told the latter that he would go up first.

Lei Tong has no objection to this, they will not argue about the so-called security issues like ordinary people.

On the battlefield, orders are heaven, and what you have to do as a soldier is to complete the tasks assigned by your superiors.

Binding Derek, Lei Tong grabbed his body and faced the direction of the coming, no matter what monsters would emerge from inside, he would hold his position to the death, and buy time for Lao Xu to climb.

After Xu Renjie finished his order, without saying a word, he stepped up to the cold iron ladder.

Due to the heavy rain a few days ago, the soaked ladder rod condensed into a fine frozen layer on the surface under the low temperature and freezing, and it was cold and abnormal for people to grasp it, not to mention climbing, it was a problem to be able to grasp it firmly.

But even so, Lao Xu still climbed fast, he was like a spirit monkey, not disturbed by external conditions at all, and after a while, he reached the top.

There is one last barrier left in front of the eyes. As long as the manhole cover on the top is removed, it should enter the hinterland of the school.

Lao Xu didn't rush to open the manhole cover, because he didn't know if the outside was really as safe as Derek said.

Rao is really so. But for a whole day, no one can guarantee that there will be no new changes in the school.

So to be on the safe side. Xu Renjie stopped at the iron ladder and listened carefully to the movement outside the well.

1 second, 10 seconds, 35 seconds, time passed like a white horse, and when 1 minute passed, Lao Xu exhaled lightly.

There was no movement, although Lao Xu heard a lot of footsteps rubbing, but those friction sounds were at least 5.6 meters away from the wellhead.

In other words. It should be safe outside the well!

Confirming this, Lao Xu no longer hesitated, he decisively stretched out his hands, held the manhole cover for two points, and then according to the force of mechanics, he used his dexterity to easily top it.

"Click!" Rao is very close and gentle, but the heavy manhole cover still inevitably makes a strange sound at the moment of detachment.

This can't help but be called Lao Xu, and the thunder pupil under the well, Derek's heartstrings tightened.

In order to avoid "scaring the snake". Lao Xu stared at the manhole cover for more than 40 seconds, and after there was no movement, he moved his arm to the right and gently moved the manhole cover to the side.

As the manhole cover moved slightly, the long-lost bright light was transmitted down. Bring some psychological security to the survivors who have been hiding in the dark for a long time.

When the manhole cover was moved halfway, Lao Xu immediately stopped, and then slowly put it on the ground.

The reason why it was not all removed. Lao Xu was afraid that in case of an emergency, he could at least rely on half of the manhole cover to block the zombie attack.

After all. It is impossible to see the real scene outside with his ears alone, and even if Xu Renjie's ears are smart, it is impossible to be 100% sure whether there are hunting zombies outside the manhole cover.

Hands on the edge of the top of the well. Xu Renjie quickly poked his head out, then rotated 360 degrees, and then quickly retracted. The whole action was done in one go, and the posture was like a turtle with a shrunken head, and after confirming the situation, it immediately retracted into the shell, without giving the hunter any chance.

"Whew~" exhaled, the situation outside was not bad, at least within the reach of Lao Xu's eyes, there was no sign of zombies. This somewhat made Lao Xu's hanging heart drop a little.

Since it was safe outside the well, Lao Xu naturally would not continue to nest, and immediately stole the bell with lightning speed, supported his arms, and then easily jumped out of the well with the strength of his legs.

After his debut was settled, Xu Renjie immediately committed himself to squatting, and at the same time held the steel knife in his hand, protecting his chest by homeopathy.

During the dance, the light emitted by the blade was particularly terrifying.

Lao Xu turned around 360 degrees again, his eyes fell on each point accurately, and after a careful inspection, he waved his hand at the bottom of the well.

Seeing Lao Xu greeting, Derek patted Lei Tong on the shoulder, and then whispered: "That, Lei Tong, Lao Xu told us to go up." ”

Lei Tong, who was staring at the depths of the shaft, did not look back, he just responded: "You go first, my palace is behind" to terminate the conversation.

For Lei Tong's command, Derek didn't mean anything.

Attacked by the zombies, he needs someone to guard him for him.

He didn't want to be dragged by brutes during his climb.

Taking advantage of the gap between Derrick's crawling, Lao Xu pulled all the half-open manhole covers open.

There was no way, neither Derek nor Ray Pupil could pass through the half-side hole as lightly as he did.

When Derek finished speaking, Lao Xu stretched out his right hand and pulled it out with his strength, then turned around again and started to guard it.

"Knock knock!" After lightly buckling the iron ladder three times, Lei Tong looked back and just saw Derek's swinging hands.

Lei Tong immediately turned around and jumped onto the iron ladder, and then climbed up quickly with a flexible pace that was extremely incongruous with his body.

Without any accidents, Lei Tong also climbed out of the wellhead smoothly.

After the three of them converged, Lao Xu motioned to Lei Tong to reseal the manhole cover.

After all, this was the only way they could get in and out of the school at the moment, and Lao Xu didn't want a fork in this place.

After properly disposing of the manhole cover, Lao Xu took Dedreka to his side, then pointed to the teaching building next to him, and asked in a low voice, "Where is it safer to climb?" ”

"Follow this drain pipe up to the second floor, and then use the window edge of each floor and the air conditioning rack to alternately go up, and then reach the 10th floor...... 1,2,3,4,5" Derek said in order of Arabic numerals, and then continued: "Reach the fifth window on the 10th floor and enter, that window is the entrance I left for coming out, and only that window has no latch. ”

Lao Xu looked up and carefully surveyed the route of Derek's actions: "Is there a guard at the window for the beasts of the "Foot Basin Country"? ”

"Usually no, I haven't encountered it when I came out anyway."

"That's a possibility." Lao Xu silently recited it all over again.

There is no doubt that whether or not the students of the "Foot Basin Country" have set up ambushes at the window is very crucial.

Because this will be directly related to whether Lao Xu and others will be attacked during the climbing process, you must know that if they are shot by the other party halfway through the climb, even if Lao Xu and Lei Tong have great ability, they will not be able to escape.

So the next climbing sequence must be done carefully. (To be continued......)
