After investing in Lu Guansheng's equipment, the company only needed to spend an additional 41 million yuan on its 170 million yuan annual expenditure, excluding the 50 million yuan in fuel tax. In other words, the annual expenditure dropped from 170 million yuan to 91 million yuan, saving 89 million yuan!

Germans are all very talented in mathematics. Not only did Hayden understand it, but the secretary also got it immediately.

"Dr. Weitzberg!" the secretary used the honorific. "With 90 million, how much equipment can we upgrade and how many experts can we retain?"

Before Lawrence Lu finished speaking, he had even better news: “You calculated wrong, it’s more than 90 million!”

"No? We won't make a mistake!" The secretary was still very confident in his mathematical talent.

"But you didn't count the diamond revenue!"

"Ah?" This time, even Hayden was confused!

"Let me ask you, what are the components of carbon dioxide? What are the components of most of the pollution in the water?" Lu Guansheng did not answer but asked back.

"Alan, do you think we're kids?" Hayden, the scientist, laughed. "Oxygen and carbon!"

“What are the ingredients of bricks and stones?”

"That's also... carbon..." The secretary also knew, "Ah!"

"Bingo!" Lu Guansheng snapped his fingers. "My device can turn this exhaust gas into diamonds."

"Alan! Are you kidding me?" Diamonds are subject to mining restrictions and are very expensive to produce!

"I'm not lying!" Lu Guansheng replied, "Every time we launch a rocket, those fifteen tons of exhaust gas can create nearly a ton of diamonds. Calculate how much a ton of diamonds costs."

"A ton...of diamonds...?" The secretary was already obsessed with money.

"How much is it? Aren't you good at math?" Lu Guansheng continued to tease the secretary.

"Fifteen... one and a half billion?"

"Not that much. Just artificial diamonds, maybe around ten billion?"

"Dr. Weitzberg..." the secretary asked in surprise.

"Can you really collect tens of billions of bricks and stones?" Hayden asked Lu Guansheng.

"Of course not!" Lu Guansheng raised his chin, "I want half of the diamonds! I can only give you 500 million, no more! I'm not a philanthropist!"

“With a spending of 91 million and an income of 500 million, isn’t that a philanthropist?” The secretary felt that Lawrence Lu was already very philanthropic!

"You made a mistake again! It seems you're not as good at math as you say!"

"How come it's wrong again?" The secretary didn't understand.

"It's 500 million for each launch! You only launch once a year?" Lu Guansheng rolled his eyes at him.

"Dr. Weitzberg, how many times a year do we launch? How many times?"

"...Ten times..." Five billion! Five billion! Hayden was also dizzy!

"Do you guys make money from this?" Lu Guansheng let them digest it for a minute before continuing, "If you do, let's calculate the money."

"Allen! If I don't make 5 billion, do you think I'm an idiot?" Hayden glared at Lu Guansheng angrily. Isn't this obvious?
