The person in charge of the monitoring and analysis room discovered an abnormal situation.

He hurriedly found Li Chen with the information.

"Mr. Commander! Come and see this!"

"Those barriers are healing themselves!"

As he spoke, he opened the holographic projection of the data in his hand.

The first show is a comparison of two ultra-high-definition pictures.

"Commander, take a closer look at these two pictures!"

The person in charge wiped the sweat from his cheeks, pointed to the picture and said to Li Chen.

At first glance, no one can see that there is anything wrong with these two pictures.

Even Li Chen didn't know why.

"It looks like the two pictures are the same..."

Li Chen stared at them for a while, then shook his head.

"Commander, this is the first frame of the surveillance screen."

"Look at the surveillance screen of the next frame!"

"The first picture is still and fixed, about three minutes ago!"

"Every picture that follows is the original picture of the surveillance screen screened out and analyzed one after another!"

"Compare and see what's different!"

As the person in charge spoke, he began to slowly play the ultra-high-definition picture of each frame of the surveillance screen.

With the continuous movement of the picture.

By the time of the third frame, Li Chen could clearly feel something was wrong.

And as the playing picture continues to coherent.

This anomaly is also becoming more and more obvious.

"Commander! These enchantments... are indeed repairing themselves! And the speed is very fast! It is calculated in seconds!"

After Dang Zhongcheng watched it for more than ten seconds, he couldn't help but turned his head to look at Li Chen and reminded him loudly.

The other commanders also saw this.

Everyone nodded in agreement.

"Compared with the initial monitoring screen three minutes ago."

"The further you go, the diameter of the gap above the colorful enchantment keeps decreasing!"

"Yeah, I can see it too! It's very obvious! This recovery speed is simply out of line..."

"We didn't even notice this before!"

"I didn't find out that it's because fighter jets and bombers have been maintaining high-intensity bombing?"

"Yeah, the movement of the bombing and the damage caused are too great, covering up this repair effect, but now with the reduction in bombing frequency, this repair effect is beginning to show!"

"What kind of high-tech is this? It's unheard of, unseen!"

"..."

The various commanders in the command center saw that the colorful enchantment would be repaired automatically.

All of them showed expressions of shock and disbelief.

On the contrary, Li Chen felt very calm, and there were not too many ups and downs in his emotions and expressions.

"After all, it is a product of an alien civilization. Isn't this automatic repair mechanism normal?"

"Why, do you think aliens are primitive animals?"

Li Chen spoke indifferently, and looked at the person in charge of the monitoring and analysis room and the commanders who were discussing endlessly.

Everyone subconsciously stopped talking when they heard Li Chen's words.

All of them looked at Li Chen with embarrassment.

They are indeed like frogs in a well.

The performance is a bit uncommon.

Being scolded is also normal.

"Commander, what should we do now?"

"The new batch of ammunition is not enough for so many fighter jets..."

Xu Ruoxi came over and asked.

There was one situation she didn't say directly.

Because besides the commanders at all levels, there are also some irrelevant scientific researchers here.

This situation is that the materials for the production of conventional ammunition are insufficient.

"Let the plane with no ammunition come back first."

"At the current ammunition production rate, how many fighter jets can be guaranteed normal ammunition supplies at most?"

Li Chen looked up at Xu Ruoxi.

"It can only maintain a consumption of 50,000 at most."

"Below this figure can barely reach a dynamic balance, and exceeding this figure will cause output to fail to keep up with consumption."

"Then maintain the bombing of 50,000 fighter jets for the time being!"

"Don't stop attacking!"

"The rest of the fighter jets are waiting for production to catch up. It shouldn't take much time!"

With previous experience in producing fighter jets, Li Chen believes that the task of producing ammunition is very simple.

Just complete the fully automatic upgrade of the production line.

At that time, move your fingers to evolve them to level ten or twenty, and the output per unit time will soar.

At that time, the ammunition produced will not be used up.

"What's wrong?"

After giving the order, Li Chen saw that Xu Ruoxi was a little embarrassed, hesitant to speak.

He suddenly frowned and asked the other party.

"General Commander..."

Xu Ruoxi blinked.

"You all go down first."

Li Chen understood immediately, and turned to look at other unrelated people.

Order them to leave the underground command center first.

Now all that is left are the core commanders of the refuge.

"Say it!"

Li Chen looked at Xu Ruoxi.

"Commander-in-Chief, we currently have insufficient raw materials for the production of conventional ammunition."

"Even if the production line is expanded, the corresponding ammunition cannot be produced without raw materials..."

Xu Ruoxi took a deep breath and replied.

"What raw materials are missing?"

Li Chen's heart moved slightly.

He remembered when he was browsing Noah's system mall just now.

Occasionally caught a glimpse of various materials for sale.

I didn't care at the time.

At this time, he subconsciously reopened the system mall.

"Many kinds of metals are missing, as well as chips, charges for warheads, etc."

According to the materials Xu Ruoxi said.

Li Chen searched in the system mall one by one.

Find all the missing materials, all of which can be purchased directly in the system store.

And the price is very beautiful.

However, Li Chen was not in a hurry to exchange these materials with Ma Commander.

He first opened the console of the production line of conventional weapons and ammunition.

At this time, under the efficient arrangement of Noah.

Intelligent robots cooperate with on-site workers to transform several fully automatic production lines.

"The fully automatic conventional weapon equipment production line produces the conventional missile 'Nulong 1', fully automatic production of 15,000 pieces per hour, and consumes a total of 1,500 first-generation second-order energy crystal nuclei."

"Equivalent to the production cost of every 10 missiles, it is a first-generation second-order energy crystal nucleus."

"This is the cost of converting the energy contained in the energy crystal nucleus into other substances instead of raw materials without using any materials..."

After confirming the unit missile production cost of the fully automatic production line.

Li Chen returned to the panel of the system mall again.

【Conventional Ammunition Package 1】

It contains enough raw materials to manufacture 20,000 conventional missiles of any type and 350 kg.

Price: 2,000 first-generation second-order energy crystal nuclei.

…

The price is really not too beautiful.

After reading it, Li Chen turned his attention to the fully automatic production line again.
