Qin Shi naturally had nothing to ask for.

But Qin Shi and Fang Mingyu underestimated Emperor Yin's shamelessness and insatiable desire. He finally looked forward to such an opportunity to open his mouth to the virtual platform lion, how could he miss it in vain?

Immediately, Yin Huangtu proposed that because of the platform's sanction of the king, Yin Tang suffered heavy losses in the next period of time, and in the next twenty years, the platform's income in Yin Tang would be more than one percent.

In addition, Yin Huangtu asked the platform to help Yin Tang train the arithmetic every year from fifty to five hundred, and the time from ten years to twenty years......

In addition, there are many requirements.

This is already the blackmail of the other party Mingyu.

Qin Shi felt too much when he heard it. But Yin Huangtu didn't care, Fang Mingyu also patiently refused, and then it quickly became a bargaining between the two sides.

Lovina listened with relish. The sky-high asking price of both sides and the landing repayment, she sees that it is not only fresh, but what can be learned from it is worth thinking about deeply.

For Yin Huangtu, what he asked for was almost unknown to his identity, but Yin Huangtu was extremely serious when he bargained, like a miser.

A cold sweat broke out on Fang Mingyu's forehead, and he negotiated with difficulty, and then continued to retreat under the insistence of Emperor Yin.

However, soon, after Luo Xingfeng, who had been silent beside him, joined the bargain regardless of his identity, Fang Mingyu was quickly defeated.

Of course, Fang Mingyu didn't let Yin Huangtu get what he wanted in the end, but he only made Yin Huangtu's request a five-percent discount......

Fang Mingyu lamented in his heart, this Emperor Yin Tang was really too picky, he was so embarrassed to bargain with him for such a small amount of money.

In Fang Mingyu's sigh, Emperor Yin patted Fang Mingyu's shoulder refreshedly and walked away.

Qin Shi also picked up his box and left with Luo Xingfeng.

He wanted to go home earlier, but Luo Xingfeng was a little impatient with the formula he had mastered, and took Qin Shi and Luo Weina and went straight to Tiangong Garden.

……

Qin Shi had already been to Tiangongyuan once. The guards of Tiangongyuan were so strict that Qin Shi was extremely impressed.

However, with Luo Xingfeng leading the way, Tiangongyuan would not have any obstacles for Qin Shi.

After crossing the gates and city walls, Qin Shi finally saw the interior of Tiangongyuan.

The entire Tiangongyuan looks like a stone castle, but in fact it is just a camouflage color. The buildings inside Tiangongyuan are almost all made of tough composite metal materials. Can withstand the bombardment of the Force cannon.

As for the interior, there are countless huge spaces.

In each area, there are a large number of mathematicians or matrix masters who are conducting research.

Along the way, Qin Shi saw countless huge matrix models, battleship plates, and other large metal machines piecing together.

The matrix masters who were dressed in white only nodded slightly when they saw Luo Xingfeng, and then continued to bury themselves in their work.

Qin Shi even saw many half-finished mechas, these mechas looked very similar to the mecha of Tianjifang, and they should be the fourth-generation mecha under the Yin Tang standard. It's just that several core technologies of the mecha have not reached the expected level, so it has not been able to enter the production stage for a long time.

When he arrived at Luo Xingfeng's office, Qin Shi took out a pen and paper very neatly and wrote out the recipe for the material. This recipe can be said to be very precious to Qin Shi, but it can also be said to be worthless.

Because the metal materials involved in it are all materials that Qin Shi himself cannot collect, and many of the materials are even the products of the Galaxy Country. It may be possible to buy it at a high price on the black market, but in this way, it will also greatly increase the cost of materials.

However, for a country like Yintang with a vast territory and relatively developed mining, the cost of large-scale use of this material will be drastically reduced, and only the cost of mining can be invested on the planet with the relevant ore.

"This recipe ...... It's a bit long...... Also familiar ......"

Luo Xingfeng was a little surprised when he looked at the formula given by Qin Shi, which had a total of sixty-three materials. Regarding the proportion of the formula and the method of fusion use, he carefully observed it for a while, and said: "This is the material formula of imitation liquid gold!" ”

"You know about liquid gold too?!"

Qin Shi looked at Luo Xingfeng in surprise.

"Haha, of course, I've lived in the City of Predators for four years, and I'm familiar with that rabbit."

Luo Xingfeng patted Qin Shi on the shoulder: "In front of Your Majesty just now, I don't want to mention this stubble." Didn't Figaro tell you that he also lived in the city of predation? ”

Luo Xingfeng was a little surprised.

"Uh......"

Qin Shi shrugged his shoulders in surprise. It's too small, isn't it?

"Looks like they haven't told you about ......"

After Luo Xingfeng sighed, he immediately ignored this topic, opened a safe protected by a heavy matrix, took out a few pages, handed it to Qin Shi and said, "This is what Yin Sa's girl gained in the predatory city before. She had gotten some metals from the City of Predation, and those metals contained a little bit of liquid gold, but not of the purest kind......"

Although Luo Xingfeng had lived in the City of Predation when he was young, he was not a master of the Matrix at that time, and he didn't know much about the mysteries of the City of Predation.

He became a Matrix Master, or after he left the City of Predation.

Luo Xingfeng's research on the predatory city still started with the metal that Yin Sa brought back.

According to these self-repairing metal materials, Luo Xingfeng analyzed some metal proportions, and on this basis, he carried out experiments, and he really experimented with a small amount of durable metal, which was used to improve the stun gun.

But large-scale production can't be done. After all, he was remodeling, but he still mixed some materials with liquid gold to make the composite material stable.

The formula provided by Qin Shi not only exceeded more than twenty kinds of metal materials analyzed by Luo Xingfeng, but also did not need to use liquid gold.

This is the value of Qinshi's formula. Because liquid gold is in this galaxy world, no ore vein production has been discovered so far. There's only one way to get this thing, and that's to tear down the City of Predation.

But the value of the predatory city is far from being comparable to liquid gold alone. Even if he threw the entire predatory city into Luo Xingfeng's hands, he wouldn't be able to do such a thing.

"Your Majesty is very attentive to you. That's a good thing, but in a sense, it's not a good thing either. Luo Xingfeng sighed. He is no longer the ignorant teenager he was fifty years ago. He knew Emperor Yin's plans.

"But don't worry, in this small pond of Yin Tang, I'll see who dares to harm you......" Luo Xingfeng said lightly: "I heard that Figaro is already a divine arithmetic, and my sixth-order matrix has also been completed quickly......"
