The magnetic accelerator cannon is a weapon that relies on kinetic energy to destroy enemy targets. Through a long acceleration track, it can even accelerate the warhead to 1% of the speed of light. At such a muzzle velocity, the warhead's armor-piercing ability is amazing.
Of course, if it is just a small vehicle or a small platform, the power of the magnetic accelerator cannon will be greatly weakened. Due to the limitation of energy storage, the initial velocity of the warhead may be less than one thousandth of the speed of light.
However, even at one thousandth of the speed of light, the projectile can still have super power. Even if it cannot kill the red dragon with one blow, it should be no problem to severely damage it. After all, it is only a small platform, so the requirements cannot be too high.
"By the way, can you design a flying unit?"
Air superiority is very important. Although facing things like red bats, any flying unit will be somewhat powerless, but it cannot be done without. It may not be of much use against alien beasts, but it is indispensable in the war with humans.
kind of unit.
Engineer No. 1 replied: "Only second-level commanders will open up plasma engine technology. With the technology we currently have, we can create rotor-type flying units."
He was not disappointed, Li Meng said: "Forget it then."
There is no need for flying units at the moment, so we cannot let Engineer No. 1 design a useless flying unit on a whim.
Li Meng asked again: "Is there any unusual movement in the nuclear explosion zone?"
In the bridge, the voice of 208328 rang: "There is no change yet, and the giant unit shows no sign of waking up."
It seems that the virus injected into the beast's nest by the new humans is really effective. The No. 1 land engineering ship is so close to the nuclear explosion zone that it did not attract the attention of the alien beasts. If it were a month ago, the alien beasts in the nuclear explosion would have been all over the nest.
And out.
There was a murmur in his heart, and Li Meng became strongly curious about the viruses used by the new humans.
If that kind of virus could be obtained, the mining base in Xiping Lake would undoubtedly be safer.
Thinking of this, Li Meng put away his random thoughts and waited patiently.
Everything went smoothly in the following time. With the transportation of thousands of people, a large amount of edible food was transported to the lower cabin of the No. 1 land engineering ship. It was impossible to fill the lower cabin. At noon
Afterwards, with about four hours left until dark, Li Meng stopped the transport team and embarked on the return journey.
For the No. 1 land engineering ship, the distance between the food city and the Qing'an shelter is extremely close, and a round trip will take no more than an hour.
Before dark, the No. 1 land engineering ship returned with a fully loaded transport team.
With the return of the No. 1 land engineering ship, the snow track outside the shelter became lively again.
It wasn't until it got dark that everything returned to calm.
Instead of leaving in a hurry, the No. 1 land engineering ship parked on the snowy road outside the shelter overnight.
Early the next morning, Land Engineering Ship No. 1 left quietly and gradually disappeared into the ruins.
The cold wind howled, in the dark sky and earth, in the world of ice and snow, on the vast river, the No. 1 land engineering ship was galloping at high speed. Wherever it passed, snowflakes flew, and the mechanical sound of tracks crushing the ice rumbled.
It came from afar, roared across the river, and then quickly went away.
In less than an hour, in a three-forked river, the No. 1 land engineering ship turned left and entered the eastern tributary.
Not far away, in the dim world of ice and snow, the mouth of the basin where Xiping Lake is located is very close at hand.
The No. 1 land engineering ship has returned here again after leaving for many days.
"The wall still needs to be built. The Ark Project is just our retreat. The terrain of this basin is very good, and there is fertile land under the snow. It can not only be used as a mining base, but also used to grow crops. The seeds in my hand are just right.
It comes in handy."
In the bridge, Li Meng sat on the large command chair, looking at the mountains on both sides of the river that were slowly passing behind.
Land Engineer No. 1 has entered the canyon and is heading deeper along the river.
"Evacuation is only a last resort. I don't like to retreat without a fight, and I won't even think about retreating before the battle. No. 1, the residential area can be designed to be simpler, but the necessary things must be there. Also, outside
A high wall must also be built, and its scale should remain the same. It is best not to use steel, which is too wasteful. Just build a stone wall. The basin is surrounded by mountains, so there should be no shortage of stone materials."
If you want to build an iron wall hundreds of meters high or even higher at the mouth of the canyon, the consumption of steel will be too great, so there is no need.
Once a strange beast attacks, there will be no difference in effectiveness between a stone wall and an iron wall. Between the two, Li Meng will naturally choose a stone wall that is cheaper and has the same defensive power.
In the future, there will be many places that will need iron resources. We should save what we can and avoid extravagance and waste.
Lowering his head slightly, Engineer No. 1 looked at Li Meng, who was sitting on the command chair, and said: "Steel can be used as a frame, and then poured with cement. In this way, the reliability of the stone wall will be greatly improved. Not only can
By saving iron resources, the structure of the stone wall will be very strong, and even if it is damaged, it can be easily repaired."
Li Meng looked up at Engineer No. 1 beside him and asked, "Can you make cement?"
Li Meng did not expect that Engineer No. 1 also knew about cement. He should have learned it from 2020.
After all, 2020 knows all of his memories and has gained a lot of knowledge about humans.
Engineer No. 1 replied: "During mining, a lot of slag will be crushed. This is the best raw material for making cement. With some chemical ingredients added, its hardness will reach the ideal state."
Li Meng said: "Let's do it this way, but what else is missing?"
Engineer No. 1 said: "Just recruit fifty more units of engineering guards. The preliminary engineering is enough."
Fifty engineering guards?
With a thought, Li Meng opened the resource page. The resources were sufficient.
As the sound of 2020 fell, in the storage area of the lower deck of the land engineering ship, around a five-meter-high iron tower, a white radiance surged out of the void and plunged into the ground.
In just one second, the white light disappeared without a trace. As the white light disappeared, in the cabin and around the coordinate tower, there were rows of engineering guards standing neatly. Their five-meter-tall height made them
It looks big, big...
At this time, outside, the land engineering ship had left the canyon and entered the basin.
Not far ahead, two city builders sleeping on the river had entered Li Meng's eyes.
