It’s not clear what Qi Lin originally dug this tunnel, but as far as the current situation is concerned, the tunnel is obviously so wide when it is formed, and all earth dragons can pass through, let alone those and A ghoul of the same size as a human being.
Although people buried a 30-centimeter-thick steel plate in the surrounding rock formation when Refuge No. 1029 was built, the steel plate was as fragile as a piece of paper in front of the earth dragon with corrosive saliva. This kind of expensive special corrosion-resistant alloy can resist the saliva of the earth dragon, but the price of the thing is too expensive, no matter which force builds the refuge, this material cannot be used to make the outer partition of the refuge.
It is precisely because of the corrosion of earth dragon saliva that the traces left by the original tunnel when it was excavated are wiped out. Qi Lin can't even do whether the tunnel was dug out by machinery or by mutant creatures. judgment.
That's a rock formation tens of meters thick! It should be known that the rock in this area is black granite with tight texture, high hardness and strong corrosion resistance. This thing is more corrosion resistant than simple steel, and it is also very difficult to excavate.
Had it not been for a natural underground cavity, the consortium would not have chosen refuge No. 1029 here—there is no other reason, simply because the excavation is too difficult.
Even humans with high-tech engineering equipment find it tricky, let alone mutant creatures with only claws and teeth.
The last time Qi Lin passed here, the tunnel hadn’t appeared yet. Only a few days have passed. Even if the diamond drill bit used for drilling oil wells is used for drilling, it is estimated that these few days were not enough. Come from a tunnel.
However, Qi Lin does not have time to delve into this issue now. The first thing he has to do is to completely block this passage to prevent more mutant biological passages from entering Vault 1029. within.
That's how it is said, but to block such a tunnel, the amount of work can be said to be quite huge...
Fortunately, in order to construct the fortifications, Zhao Weiju's men brought several engineering armors. In addition, there is a medium-scale cement production plant in the occupied area.
If you want to open such a tunnel, there must be a huge amount of earth and stone to be dug out, but just like the excavation method, these missing earth and stone have also become a mystery-in short, Qi Lin is inside and out of the refuge. There was no trace of the excavated earth and stone around.
There is no way, Qi Lin can only ask the soldiers to dig the rock wall on the edge of the refuge, and use this method of "dismantling the east wall to make up the west wall" to fill the tunnel.
The high-power cement mixer ran on the open ground and made a huge roar. Although this noise may attract mutated organisms on the surface, Qi Lin would rather take it than the trouble during transportation. risk.
The stones excavated from the rock wall, the broken bricks from the destroyed block, etc., mixed with the cement, little by little piled up in the tunnel.
It is impossible to block the entire tunnel, Qi Lin can only block one-third of the length, but even so, it is impossible for ordinary mutant creatures to use their own power to block the tunnel. Get through again.
As for the "mysterious force" that digs the tunnel at the beginning, Qi Lin is too lazy to take care of it. If this "mysterious force" really wants to dig another tunnel, it will be basically nothing to block all and one third. the difference……
"Put these things into the concrete, too." Zhao Weiju, who escorted the prisoners, has also returned. He also asked his men to gather all the discarded steel in the occupied area and transport them to the tunnel entrance to add these things. Into concrete, the strength of concrete can be significantly improved.
Several engineering armors held a thick tube with one person, and the nozzles were continuously sprayed with evenly mixed concrete. The soldiers first piled scrap steel and bricks in the tunnel, and then poured concrete on the steel. After this layer of concrete has solidified, repeat the first step of stacking scrap steel and masonry.
The progress bar of the blockade project was advancing gently, and Qi Lin took advantage of this time to hand over the command of the Lexington Shield Consortium's armored forces to Zhao Weiju's hands-now, it was almost time to leave.
"When the fight is over, I invite you to drink." Zhao Weiju patted the smooth shoulder armor of Thor's Hammer, Qi Lin also smiled heartily: "Well, I will kill you a lot by then."
"Oh, I forgot to say, I treat, but you pay."
The two were joking with each other, but they all knew...this war is far from over~EbookFREE.me~ and it is completely unknown whether they are all alive until that day.
"All in all... take care, don't hang up easily, remember you still owe me a drink."
"So are you. Well, but you have a strong group of guys, with such awesome armor, it's not easy to die."
After saying goodbye to Zhao Weiju, Qi Lin hurried back to the Eagle Station, and just happened to ran into Parsefanie who had just walked out of the station restaurant.
"I heard, you are leaving, right?" Pasifani did not try to seduce Qi Lin surprisingly. On the contrary, there was a trace of sadness in her clear eyes.
"Um... I'm leaving, actually..." Qi Lin looked around, then lowered his voice, "You better leave here too, this may soon become a frontal battlefield, and the Lek Star Shield Consortium is here. There is no benefit from this place."
"I know." Passerfani said, pulling a strand of hair behind her ears, "but the people above don't think so much. In their eyes, since the price has been paid, then the deal must be completed, no matter What is the last thing you can get."
"Then you have to stay here forever?" Qi Lin frowned. Zhao Weiju is a soldier, and it is his duty to stay here, but Pasifani is not.
"That's not true. The consortium can rest assured that such a new district full of development potential will be handed over to me. After they elect the governor of the new district, they should come over to take over my work."
"That's good, be careful yourself." Qi Lin breathed a sigh of relief when Pasifani said.
"Well, then, see you next time..." Passerfani hugged Qi Lin's neck, and after a deep kiss between the two, she watched Qi Lin get into the returning train.
