Over time, more and more zombies hovered in the sky over the temporary base.

    At a glance, it was like dark clouds covering the top. It was no longer thousands, at least 100000 or nearly millions, just like the previous zombies attacking the city.

    With the dense sky, zombies hit the cabin of the temporary base, and flesh and blood adhered to the cabin. After being processed by wind and snow, they became a layer of blood frost, completely blocking the internal line of sight. Lu Xiping and others can only understand the outside situation from the command center. However, with more and more zombies around, the wind and snow became bigger and bigger, and gradually formed a thick whirlpool cloud in the high altitude, This also blocked the perspective of the satellite, and the luxiping people in the temporary base immediately lost all sources of external intelligence, just like losing their eyes, which made everyone in the enclosed space uneasy.

    Jiang Dashan swallowed his saliva and said, "listen to the formation of this voice. I''m afraid that even if the air force support arrives, it can''t get close. Instead, it will be besieged by countless sky zombies. This is not good news."

    "Captain, we can''t wait to die!" Nalan Yun suddenly stood up and said.

    Lu Xiping sighed softly and said, "Hey, although the command center will find a way to solve this dilemma, you might as well say what you have to say."

    "Or we''ll kill out!"

    Leng Chaoyang said coldly, a pair of eyes are very firm.

    Lu Xiping rejected this method. Without knowing the distribution of zombies outside, killing them is equivalent to death.

    Then Huang Feiyang, Meng Fei, Zhou Chu and Nalan Yun all mentioned the methods they thought of, but none of them could be used. When the people were silent, Liu Huijun suddenly said, "I thought of a way. Since we can''t get out of the sky and the earth, why don''t we learn bunker tactics and get out of the earth?"

    "Your method is interesting. Go on." Lu Xiping''s eyes lit up.

    Encouraged, Liu Huijun went on happily: "Instead of sitting empty in the base waiting for rescue, we might as well dig a tunnel by ourselves. Even we can let the command center send an engineering team to dig in from the outside, which can greatly reduce our time and let us leave here without disturbing the zombies outside!"

    Everyone in ares team thinks this method is very good.

    Lu Xiping immediately fed back this method to the command center. At this time, the command center was discussing how to support the air force to safely approach the temporary base. After hearing Lu Xiping''s report on Liu Huijun''s method, Qin Weiye, Liu Yang, Zhou Yalan and others all brightened up.

    They may not need the air force to approach the temporary base.

    They immediately perfected Liu Huijun''s idea, and finally selected a location without zombies for excavation, which is about 10 kilometers away from the temporary base. In addition, the command center also designed an excavation map, which carefully marked the excavation direction of the Ares team, so as to connect with the tunnel dug by the engineering company.

    When the plan was finalized, both sides immediately acted at the same time.

    In addition, in order to avoid the discovery of zombies outside the excavation point, the command center also sent two UAV teams of the second group army. These UAVs are all controlled by 5g. In order not to eliminate zombies, they mainly lead nearby zombies farther away. In this way, even if the UAVs are destroyed, there is little loss.

    After all, there is no one above. Talents have always been the greatest wealth of a nation.

    The Ares team led by Lu Xiping took all the food and water and used the tools in the temporary base to dig out the tunnel. On the other side, the command center sent an engineering company with the most advanced excavation machines to quietly land at the already planned excavation point, and then arranged the excavation according to the planned drawings.

    In this way, the Ares team dug out and the engineering company dug in.

    The ten kilometer tunnel is neither long nor short. If only the Ares team excavates manually, it must be very slow, but fortunately, the engineer company has excavation machines, which can dig about 5 kilometers a day. The ten kilometer tunnel can be completely opened in two days!

    After seeing the tunnel open, the members of the Ares team led by Lu Xiping couldn''t help crying silently. This is a country''s industrial capacity. It''s great that China can establish the most perfect industrial system in the world on the eve of this disaster. This is also the main reason why China can become the only surviving country of Bluestar.

    All development has its causes and consequences.

    After the tunnel was opened, the Ares team immediately returned to the temporary base, took the mother virus carrier, Mo Qiankun, and some necessary items, and left the tunnel with the comrades of the engineering company. At the other end of the tunnel, a carrier plane had been prepared. When Lu Xiping and his party got out of the tunnel, they could directly enter the carrier plane.

    "Rumble..."

    At this time, however, a strange sound suddenly came from all around, accompanied by the tremor of the earth.

    At first, Lu Xiping thought it was a large-scale land zombie. He found that they were moving. However, he found that it was not so simple. After all, even if millions of zombies were moving, it should not cause such a violent vibration. It seems more like an earthquake!

    Thinking of this, Lu Xiping suddenly had a bad idea in his heart.

    He shouted for the first time: "no, it may be an earthquake. The people behind us come out quickly."

    Before he finished, he ran back and urged his teammates to run. Some comrades in the engineering company were experienced and knew that it should be a shock. They immediately organized people to set up simple support in the tunnel, because the tunnel they dug was not reinforced with concrete like a shield machine, otherwise it would not be possible to dig through in two days, This kind of soil tunnel is extremely dangerous in case of earthquake.

    Lu Xiping had no time to take care of his own safety.

    As he ran back, he urged the people to speed up their steps. When he ran to the end of the team, he saw that the last person was Jiang Dashan. He stretched out his hand and wanted to pull Jiang Dashan, but he didn''t want Jiang Dashan to be low. He hit his hand heavily and slipped down. When he saw it, he knew that the tunnel above Jiang Dashan had collapsed, He was pressed down by a lot of earth and stones.

    "Captain, you go quickly. Leave me alone. You can''t get out if you don''t go again!"

    Jiang Dashan realized that he might not be able to get out, so he was ready to sacrifice and ruthlessly pushed away Lu Xiping''s hand.

    Lu Xiping did not leave. He shouted anxiously that the comrades of the engineering company came in with the excavation tools. At this time, the intensity of the earthquake became higher and higher, and the whole tunnel shook violently.

    Seeing this, Jiang Dashan said anxiously, "Captain, leave me alone. If you delay any longer, let alone yourself, people outside may also be found by zombies. At that time, you can''t go. It''s not worth hurting everyone for me."

    Seeing that Lu Xiping was indifferent, Jiang Dashan then advised: "Captain, I believe you are the same as me. If you join the army in this situation, who is not ready for death? We should have been indifferent to death long ago. You don''t have to care so much. If you are pressed here today, I will abandon you for more people. Therefore, for the sake of the overall situation, you should leave quickly. You are more important to China if this rejuvenation movement If you move, you must sacrifice. Of course, it''s up to us old friends. You young people are the future of China, and the future of China depends on you! "

    With that, Jiang Dashan took a bloody wallet from his body and asked Lu Xiping to give it to his family.

    Lu Xiping did not know when his face was full of tears. He had just received the bloody wallet. The vibration of the whole tunnel suddenly intensified. The soil under Jiang Dashan collapsed. The whole person slipped down and was completely buried by the soil. It was late when the comrades of the engineering company arrived with tools, so they had to take Lu Xiping to quickly escape the collapsing tunnel.
