All night, at this construction site, 700 people were working enthusiastically.

In order to keep everyone energetic, Ye Feng basically changed shifts every two hours. In this way, these members could maintain their best condition within two hours and excavate the fastest.

As for the rest members, they are also responsible for the vigilance work, which can release more labor.

These people are all evolvers. The two-hour rest time, coupled with sufficient food and evolutionary meat supply, is enough to restore them to their peak.

Soon a night passed, and that night, they arranged fifty outlets.

You should know that laying out an exit is not only as simple as excavation, but also to make it reliable enough, and even if the main battle tank is opened in the face, there is no clue.

In order to achieve this goal, it is not easy to strengthen the surrounding walls of the hole with a large amount of quick-drying cement.

As for the entrance of the cave, a piece of stone slab was placed, and then a cutting machine was used to make stone pillars to support the stone slabs, and block them with cement.

Of course, there is also a problem with this, that is, the outlet is so firm that they cannot get out at once.

Finally, after discussion, I still felt that the blasting method could be adopted so that the hole could be opened as quickly as possible.

Of course, in order to prevent people from discovering that they will not install bombs at the entrance of the cave. When the attack is launched, they will be brought in directly from outside and then manually detonate.

In order not to block the hole from collapsed stones and soil, they also had to dig the hole five meters deep to use it to load the soil and stones falling off the filling surface.

Finally, he piled up the outside of the hole and modified it so that he would be the same as usual.

When Ye Feng and others finished all this, the sky finally began to brighten, and they also quickly evacuated here with their tools.

It is relatively hidden at night, but during the day, others may be able to discover the situation here several kilometers away. If the remaining exits continue to be mined, it will greatly increase their exposure risk.

So during the day, Ye Feng chose to dig the tunnel, at least dig the tunnel at the entrance first.

Of course, the choice of the entrance also requires some careful consideration, so Ye Feng’s final choice was to set the entrance location in the suburbs not far away.

At that time, their army will be in this direction. If the Dragon Teeth Team appears here, it will not be very abrupt.

Thinking about it, under Ye Feng's command, these members of the Dragon Ya team took action quickly. In order to facilitate excavation, they found a house with a courtyard to start.

When digging the tunnel, the tools Sun Xue suggested came in handy, such as trolleys, electric lights, etc.

Fortunately, the terrain here is relatively high, and even if the tunnel is excavated, there is not much water accumulation, so the water pump is not used for the time being, which also reduces a lot of trouble for everyone.

The project is advancing rapidly, with some responsible for excavation, some responsible for transporting the soil, and some responsible for strengthening the hole wall with quick-drying cement.

Since everyone is an evolutionist, even if it is manually excavated, the work efficiency is a bit terrible.

It took only half a day to dig out an authentic tunnel that was nearly three thousand meters long.

By the afternoon, they were already expanding their branches and connecting this main road to other exits.

Moreover, because these branch tunnels are smaller, the excavation speed is faster. After one day, they have strengthened the main tunnel and nearly twenty branches have been dug.

We can dig out the other fifty outlets tonight and connect them to the main tunnel. After that, the completion will be completed, according to the current progress, it will only take one day at most.

Ye Feng looked at the sky. It was already past 5 o'clock in the evening. Seeing that the plan was implemented normally, he could leave for a while.

Ye Feng called Xu Youcai and said directly: "The next thing is left to you. If you have completed this project and have more time, try to explore more exits as much as possible, so that we can have more choices when attacking."

After hearing Ye Feng's instructions, Xu Youcai was slightly stunned and said in surprise: "Boss, are you going to leave here?"

"Well! I'm going to Shuangzhou City to see how the situation is there. Don't worry, I'll come back before the war starts." Ye Feng patted Xu Youcai's shoulder and said with a smile.

After hearing Ye Feng say this, Xu Youcai felt much more at ease, "Boss, don't worry! I won't make any mistakes when I leave it here. I'll wait for you to come back and take us to create."

"Don't worry, I will definitely do it." Ye Feng said, then left the tunnel and took out the motorcycle from the evolution box, but he did not go directly to Shuangzhou City, but went back to Xin'an City first.

The one Ye Feng handed is just an ordinary men's motorcycle with a maximum speed of more than 100 kilometers. If it was faster, the car would feel like it was floating, so he needed to go back and change to a better car first.

Back at the base, Ye Feng went straight to the garage of the apartment and took away the Lamborghini treasured by Xu Youcai.

Luxury cars like this are extremely popular even in the end of the world. Even Xu Youcai only collected one.

Ye Feng took Lamborghini into the evolution box, then left the base and took it out when he arrived at a place where no one was around.

The roar of the engine sounded, and it accelerated from the start to 100 kilometers per hour. It took only 2.8 seconds. The powerful feeling of pushing back was so exciting that even with Ye Feng's mentality.

The engine roared, Ye Feng stepped on the accelerator to the bottom, and the Lamborghini's speed instantly rose to 320 kilometers per hour. Such a terrifying speed, if you are not careful, it will be the end of the car being destroyed and the people being killed.

Even Ye Feng needs to release his full mental power, because this is the end of the world, and in this road situation, traffic accidents are prone to occur. If he really crashes, he will be seriously injured.

However, Ye Feng's mental power is strong, and he can fully exert the speed of the car. He set off around 5 pm, and not long after 6 pm, he had already crossed more than 300 kilometers from Xin'an City to the near Shuangzhou City base.

At a range of two kilometers away from the other party, Ye Feng put away Lamborghini and walked towards Shuangzhou City.

Now is the peak period for those survivors to collect supplies and return to the base. Under such circumstances, it is easier for Ye Feng to get in.

Of course, before this, he must pretend, otherwise it would be strange if he goes in as he is now and is not noticed.
