"Of course, it's just a bit more expensive." 。The entire doomsday fortress is actually a huge monolithic structure. During its construction, it would use caisson construction methods to continuously sink the building underground. Ultimately, it could potentially sink hundreds of meters underground. You can imagine this structure as a super skyscraper sinking hundreds of meters underground. It has an independent energy system and a capable ecological system... Xu Huasheng said directly: 。The design plan for the Doomsday Fortress was actually already in place. 。But this thing is too expensive to build. Constructing such a fortress is like using caisson technology for piles, slowly sinking the entire structure underground. When the depth is sufficient, even a nuclear attack won't be able to damage the underground city. 。Saliva, Salman could hardly contain his drool. 。This thing is great, a super turtle shell. If anyone hits us, they can't beat us, just dive into this, no one can do anything about it. 。This base can also produce things, and if it can't beat them, it hides and accumulates over time before counterattacking. 。"Xu, how much money would it take to build such a doomsday fortress" 。"Your Highness, this is hard to say. It depends on the scale and the specific construction difficulty." 。This thing is not something that can be built just anywhere. 。A specialized geological exploration team must first conduct an exploration and select a suitable location. 。Then, based on the geological conditions, design and construction plans are formulated, and the construction methods are determined. It also depends on the internal configuration. 。For example, building a doomsday bunker that can accommodate millions of people. If the geological conditions are favorable and the construction difficulty is low, it might be possible to build it for one or two hundred billion dollars. 。"But if the difficulty is high, it might take four or five hundred billion dollars, or even more...",Although Saudi Arabia is wealthy, it has spent a lot of money buying things from China over the past two years.,Now, Saudi Arabia also has limited cash on hand. 。But what oil sands have is nothing more than increasing production capacity. 。Now China's demand for oil is constantly increasing, and oil can also be exchanged for money. 。"No problem, Your Highness. When doing business with our Hua Xia people, we focus on flexibility." 。Xu Huasheng smiled, but sighed helplessly in his heart. 。It's a pity that China's strength isn't strong enough now. Otherwise, with this opportunity, it could have pushed Saudi Arabia and China to settle using the renminbi. 。But now it's impossible, China doesn't have enough strength yet. 。If Saudi Arabia and China settle oil transactions in yuan now, the United States would immediately turn its guns on China. 。Currently, China cannot come out and must bide its time. 。When our strength is sufficient, that will be the time when China truly turns the table. 。And this time will not be too long, as long as the United States continues to act recklessly and jump into pits, the so-called hegemony of the United States will gradually be shattered. 。"Xu, there's one more thing..." 。After talking about the dungeon, Salaman looked at Xu Huasheng and said in a low voice. 。"Your Highness, you said..."Xu Huasheng looked at Salaman. Generally speaking, when the big dog owner asked for something, there was money >>> 。"Xu, we in Saudi Arabia want to invest in an aerospace company in your Hua Xia. We mainly want to develop commercial rockets and satellites. Can you help me ask about this Money is not a problem, it's just that our technology is not very good..." Salman made his request. 。Saudi Arabia wants to invest in a civilian aerospace company in China, to research civilian rocket technology, satellite technology, and so on. 。The Sahara has wealth, while China has talent and technology. 。Xu Huasheng looked at Salman, knowing Salman's intentions. 。They want to use money to accumulate their own technology in China. 。Even though it's civilian rocket technology, it's still rocket technology. 。If something can make a rocket fly, then it can also make a missile fly. 。。
