"Prince Salman, no problem, building an underground city, this is something we are very experienced in. Your Highness, come, let's sit down and talk slowly. What kind of specifications does Saudi Arabia want for its underground city" 徐華盛 smiled and asked. 。"Specs Does an underground dungeon even have specs" 。Of course, different needs mean different specifications. 。For example, an ordinary-level dungeon has the ability to provide shelter and air raid protection, capable of defending against ordinary aerial attacks…” Xu Huasheng began explaining the different levels of dungeons to Salem. 。What is called "grading" is actually just a difference in defensive capabilities. 。Salman listened very attentively, the more he listened, the more he wanted 。"Prince, the last one was amazing." 。The last one is a doomsday-level dungeon, also known as the Doomsday Fortress. 。The scenario is a global full-scale nuclear war erupting, plunging the entire Earth into an apocalypse. 。...And this underground city requires a complete defense against a saturation nuclear attack, and the underground city must have a complete ecosystem to ensure that the underground city can survive forever underground…",Things of this level, building naturally have a higher difficulty.,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. 。。
