Feeling the "crazy" joy in Han Feng's heart, Luna just watched quietly without saying anything.

"Luna, how big is the base vehicle?!"

"Report to the Korean team... big..."

"Haha~ Look at this thick construction book! You don't need to think about it to know that this is a huge thing."

"..."

"Luna, will the base vehicle really deform?"

"Report to the Korean team...will..."

"Haha!!! I knew it! I knew it!" Han Feng kept talking while holding the construction book.

After several useless questions, Han Feng finally calmed down. Then he opened the first page of "Allied Base Vehicle Internal Structure Diagram" with hands trembling with excitement.

A few seconds later, Han Feng stared at the content on the first page for a moment. On the first page of the construction plan, he saw four quite decent words - Construction Instructions.

Looking at the content of the construction instructions, Han Feng whispered: "First, building an Allied base vehicle requires at least fifty engineers to work together..."

"Second, the main materials needed to build the Allied base vehicle are 4,500+ tons of steel, 1,000+ tons of zinc, 600+ tons of copper, 120+ tons of lithium, 1.5+ tons of beryllium, 500+ tons of titanium, 300+ tons of aluminum, and 1.8+ tons of vanadium.

, germanium 0.6+ tons, scandium yttrium 3+ tons, lanthanum 0.4+ tons, cerium 0.4+ tons, neodymium..." After seeing half of it, Han Feng felt dizzy. Just this second item

, there are several rare metal materials that he cannot name.

If the first construction condition requires fifty engineers, Han Feng can issue a summons order to satisfy it in minutes, but... this second condition really gives Han Feng a headache.

"What the hell...where can I go to prepare these materials?" Frowning, Han Feng continued to look down.

"Third, the construction site shall not be less than 2,000 square meters, and the height shall not be less than 20 meters."

"Four, from the beginning to the end of the construction of the Allied base vehicle, the construction time is about three to four months. The specific construction completion time shall be subject to actual conditions."

"Fifth, during the construction period, no unrelated personnel are allowed to approach the construction site within a radius of five kilometers (red police units ignore this article)."

After Han Feng finished reciting these five construction instructions silently, he raised his hand to turn the page and looked at the back. He found that there was a blank paper at the back, which meant that there were only five construction instructions.

Closing the construction book, Han Feng took out a cigarette and lit it...

Looking at the misty smoke, Han Feng thought that items 3, 4 and 5 were easy to solve. Now is the end of the world, and he can find empty no-man's land to build. Although three or four months is a bit long, it can still wait.

I can afford it. As for leaving no one around, that would be even better. Just let a few teams of troops garrison at will.

The only thing that gives Han Feng a headache right now is the second item of the construction instructions... Thinking of the "dazzling array" of construction materials I just saw, I really feel like crying.

"Luna...this material..."

"Report to the Korean team that you can collect as many materials as you can. The remaining materials that are not found in nature can be synthesized and manufactured by the combat laboratory." Although Han Feng's question was just the beginning, Luna already knew and detailed it.

Explain it to him.

"Um...how many gold coins will it cost if we let the combat laboratory produce these materials?" Han Feng knew the "urinary nature" of the system. Although anything produced using the system would be high-quality... it would also be expensive.

"Report to the Korean team that the price of any rare material is two thousand gold coins per ton."

"How heavy will this base vehicle be when built? How many rare materials are needed?"

"Reporting to the Korean team, the base vehicle has been built and is expected to weigh about 7,000 tons. The rare materials are about 50 tons."

After listening to Luna's words, Han Feng lowered his head and smiled, thinking that the system is indeed dark enough! Excluding steel, copper, titanium, and aluminum that are relatively easy to obtain, if the remaining materials are made by the combat laboratory, it will cost 2.1 million.

Gold coins! Isn’t this ridiculous?!!! More than two million gold coins! I can’t even grab it!!!

Putting down the cigarette butt, Han Feng was still thinking about another thing, which was where to get these materials... Steel, which is in the most demand, is all over the streets. Even if it is made from iron, there is enough supply. But this 1,000-ton zinc

...It’s a big head!
