"Humph! By the time you say it's started, the day is over! Erin looked at Li Chendao, who had just called up the terrain hologram, dissatisfied, "We have carefully studied this terrain a few hours ago!" The construction plan has also been laid out in advance, and there is no need for your help at all! ”

Li Chen was very confused about Erin's dissatisfaction, obviously Murong Zhilan asked him to do this, with Erin's respect for Murong Zhilan, he shouldn't have said such willful words, or this was simply what Murong Zhilan asked her to do, in order to give herself, a newcomer who had just integrated into the collective, a dismount!?

Li Chen shrugged his shoulders but still said, "Since Sister Zhilan said that she wants me to be the commander-in-chief, then you must listen to my orders!" Let them stop! ”

Li Chen didn't have any thoughts of pity and pity now, after all, he and Liu Yu were going to leave here after all, and they had to have enough information before leaving here! If this base is not completed under your own planning, how can you leave a back door to escape!?

"Humph!" Erin turned her head angrily, and her golden double ponytail flicked a perfect amplitude behind her head, but she didn't ask Murong Zhilan again, so she naturally obeyed Li Chen's order and stopped all those engineering vehicles.

The hologram on the engineering vehicle is not a real-time hologram, and none of the engineering vehicles has released drones after leaving the Baron, so this hologram was taken by the previous batch of robots and Baron who landed on Mars in advance when they landed.

After carefully observing, Li Chen made a mark on the hologram after confirming that Erin's previous location was indeed the most reasonable location, "Drill a hundred meters inward from here, and only drive three lanes!" Lateral drilling at 20 meters! ”

Li Chen said that he started to make a schematic diagram on the main engine of the engineering vehicle, and since Li Chen's idea is a temporary base, the simpler the better, so the schematic diagram of the base he designed is simply an ordinary base model that is very basic.

The boxy layout is 200 meters long, 80 meters wide, and 5 meters high, and in the center of the base is a 20-meter-long, three-lane passage leading to the valley. This is the floor space required for the temporary base designed by Li Chen.

Erin watched Li Chen send the layout plan to every engineering vehicle, Qiong's eyebrows were getting tighter and tighter, she had never seen such a bad base model, the boxy design method was designed by a kindergarten child! But she still didn't say a word, watching Li Chen continue to perform.

The other ordinary soldiers who operated the engineering vehicle would not have the thoughts or questions that Erin despised Li Chen's design, they would only resolutely complete the tasks assigned by the members of the command room, even if the base was designed to look like a toilet, they would still unswervingly complete it.

"Every meter of excavation must be reinforced with a good vault! We don't have time to waste on rework! "Once Li Chen enters the working state, he doesn't even pay attention to some of Erin's small actions, even if this base is just a temporary base, it is also his work, and every new work of his will let him put all his energy into it.

While Li Chen was in command, the engineering vehicle they were in was not idle. With Liu Yu's help, the armored engineering vehicle closed all the air holes, opened all the armor protection and the air internal circulation system, and began to drill directly into the rock wall to the north at the next position.

Since it is a base built in the middle of a rock mass, it is clear that one passage is not enough, and it is necessary to allocate at least two or more backup passages for the convenience of daily life or for safety reasons. Li Chen is now making preparations in this regard.

"Hey! What are you doing? Why do you want to turn off the sensor image too!? Li Chen suddenly turned off all the induction systems of the engineering vehicle, which made Erin immediately vigilant, and a pair of apricot eyes stared at Li Chen's hands tightly, as if as long as Li Chen dared to make any superfluous movements, she would directly cut off Li Chen's hands!

Although Li Chen did close the sensor image and the surrounding windows, he really didn't have the unhealthy thoughts like Erin's heart. To be more precise, he didn't dare to have superfluous thoughts at all, after all, the people in this carriage were except for Erin and Liu Yu, the two rookies in the acquired realm, but the real horror was the woman who had been teasing Xiao Hei who had been pretending to be indifferent to the current situation!

Since the last time he came back from the spirit world, Li Chen found that Murong Zhilan's hidden momentum in his body was even more terrifying than Shi Da, although Murong Zhilan was hidden, but at that time, Li Chen's body was supported by the starlight divine power, and it was easy to sense the spiritual power hidden in Murong Zhilan's body.

This is also the reason why Li Chen has not dared to easily disobey Murong Zhilan since then, after all, this is the real world, it is the base camp for which he is fighting, he doesn't want to be wiped out by Murong Zhilan before he escapes the blood clan base!

Li Chen ignored Erin's eyes, and naturally turned on the sensing image, in fact, he just forgot the operation command of this ordinary armored engineering vehicle's sensing image for a while.

The opening of the sensing image means that the engineering vehicle is connected to the control system in the command room, and the movement coordinates of all units can be seen through the control system on the Baron. And Li Chen can also see all the other units belonging to the blood clan through the auxiliary map on the engineering vehicle.

Now, in addition to the more than 20 engineering vehicles outside the Baron, there are only the row of robots on the cliff and the two teams of soldiers who are rapidly climbing towards the top of the cliff.

Li Chen and Liu Yu coordinated to control the engineering vehicle to drill into the cliff, and with the Baron on the outside as a reference, Li Chen could easily correct the forward track and drill forward in the direction perpendicular to the cliff.

Liu Yu controls the robot that comes with the engineering vehicle to transport the crushed rocks. The rocks of this cliff are very solid on the whole, and in Li Chen's opinion, as long as the mountain below is not hollowed out, there is actually no need to do top protection.

But construction safety is the focus that needs to be the top priority in any era! Li Chen is still careful to do a good job of mountain reinforcement every time he drills a one-meter cave, with the new era of high-energy compression technology, many of the rocks that have been dug down can be used by engineering vehicles to strengthen the mountain.

The pre-construction work of the temporary base has actually been simple repetitive, Li Chen has adjusted the work of other engineering vehicles at several key points in time, maximizing the use of all labor, and the rest of the time is just at the mercy of everyone.

Twenty armored engineering vehicles are not special engineering vehicles, but this kind of engineering vehicles are indeed good at drilling holes, with the support of new materials, there is no need to consider various interference factors such as cooling, wear and tear, and energy consumption, and it only consumes a morning's time to open up the space that Li Chen expects.

If it is placed in the first half of the 21st century, it may take a day to open a tunnel of more than ten meters under the condition of using explosives and a lot of manpower.
