He Yan knew that Benson would not nod easily, and he was ready to accept the test before talking, so he agreed without hesitation.

"I hope your ability can match your courage." Benson patted He Yan on the shoulder, and asked his subordinates to take He Yan away.

On the same day, Benson arranged a two-story house for He Yan's "family of three" in his own jurisdiction, mainly to facilitate his supervision.

The house is not big, only 70% new, but it is much better than the previous rental house, at least there is no lingering musty smell, and the light energy in the house is sufficient, unlike the rental house that is dark all year round due to unstable energy .

The first floor of the house is a standard two-bedroom, one-living room with an independent kitchen and bathroom. Half of the second floor is a terrace and half is a storage room.

He Yan is quite satisfied with the house, especially the empty storage room on the second floor, which is just right for converting it into a studio.

As long as Xiao Mili has a shelter from the wind and rain, she is very happy, especially if she can stay with He Yan and Lan Xing.

Lan Xing didn't have any complaints about the house itself, but he complained about the number of rooms, and asked if the worm who showed them the house could smash the wall between the two rooms.

After getting an affirmative answer, he planned to tear down the wall by himself, but luckily He Yan stopped him in time.

"Then I want to sleep with you." Blue Star wasn't shy at all in front of the worm.

The female who brought them to see the house was the cold-faced thug who led He Yan to the mine that day, and was assigned by Benson to assist He Yan for a period of time, which was actually just surveillance.

Because this worm has almost no facial expressions, He Yan has some doubts about whether it is artificial intelligence or something, and plans to borrow it to study it when he gets acquainted with Benson someday.

But after hearing Lan Xing's careless words that made the insects daydream, the cold-faced thug's eyes uncontrollably glanced at He Yan and Lan Xing's necks.

The worm pattern on Lan Xing's neck would retreat under his collar when he was in a happy mood. At this time, he should be in a good mood, and the entire length of his neck was white and clean, just like a male worm.

And He Yan, in order to let other female insects see his insect pattern, so as not to cause unnecessary misunderstanding, the insect pattern is always posted higher than the collar.

After the cold-faced thug hurriedly glanced at the necks of the two worms, he showed a clear look, and looked at He Yan with a little more envy in his eyes.

He Yan: ...

"Mi Li, you are already a big bug, it's time to learn to sleep by yourself, you sleep with us, He Yan and I can't let go, and when He Yan wakes up, he still has a backache." Lan Xing said earnestly to Mi Li said.

After hearing this, the cold-faced thug looked at He Yan worriedly, and He Yan read out his OS without hindrance: Little brother, can you do it?

Finally sent away the cold-faced thugs who wanted to stay and watch the excitement, and solved the problem of room allocation-moved all the beds to one room, and the other room was used as the training room for Blue Star and Millet, He Yan Only then did have time to look at the information about slow-moving mines.

He asked Benson for these materials, and Benson didn't fully trust him yet, so he only gave some materials that didn't involve important information, but they were enough for the current problems that needed to be solved.

In the next two days, He Yan read the information about minerals in the past two years, and learned about the situation of several industries with the largest demand for mines and the level of space shipping.

Five days later, he handed over a marketing plan to Benson.

It took Benson nearly an hour to read through the not-so-thick business plan, during which time he drew out his optical brain to check a few data.

"Reduce the price of rare high-grade mines by 5%?" Benson slammed the proposal onto the table, "Oh, thank you for thinking it out."

He Yan was not in a hurry to speak. His ideas and data were all in the plan. Those data were not fabricated out of thin air, but calculated from the actual situation. He believed that Benson would not fail to understand.

Benson rubbed his fingers, his eyes didn't fall on the ground, and he began to think about the feasibility of this plan.

He Yan sat on the opposite side and waited patiently.

After a while, Benson paused with his fingers, his eyes fixed, and without asking another question, he made a decision and said, "Okay, just do as you said, and you will get the first commission from our cooperation after it is done."

He Yan did not expect such a straightforward decision. He thought that Benson would ask some more questions, or say some things that would kill him if things failed, but Benson just agreed.

In the following week, Zerg's major mining industries received a message through various channels: the mining boss of planet 2779, Heijie, wanted to sell off the rare high-grade ore in his hands at a reduced price, and would no longer sell them in the short term. Order online, first come first served.

After confirming the accuracy of this news, many companies' cargo spaceships flew directly to planet 2779, scrambling to buy goods, and when they left, they not only bought rare high-grade mines with a 5% price reduction, but also bought high-grade mines. The base mine is 12% of the market price.

The number of high-grade ores is scarce, and the number of basic ores is large. The 2% higher is just equal to the 5% of the price reduction, and the other 10% is the value agreed in the bet.

In less than a month, He Yan completed Benson's test.

——

"how did you do it?"

If the operation of the brain relies on gears, the gears in Dali's head must be making the sound of jamming at this moment.

"Marginal benefit." Faced with Dali who came to give him money, He Yan was very patient, knowing that Dali didn't understand, he explained persuasively: "Do you know the operating cost of a cargo spaceship?"

Shaking his head vigorously in confusion.

He Yan clicked out the virtual whiteboard of the light brain, zoomed in and stood between him and Dali, and wrote the number "100" on it casually.

"Assume that the one-way cost of a cargo spacecraft coming to 2779 is 100, the round trip is 200, the cost of going to the nearest planet from 2779 is 80, and the cost of returning to your own planet is another 80." He said while talking on the virtual screen. Write two "80" before "100".

"Then it wants to buy other minerals after purchasing high-grade ores in 2779. He has two options. One is to fly to other planets to purchase, which will generate a cost of 160, which is more expensive than purchasing directly in 2779." It's..."

He Yan put a plus and minus sign between two "80" and a "100", and now he understands it vigorously.

"The cost is 60 more." Dali replied.

"Yes, as long as the increase in our ore price does not exceed the cost of 60, in fact, even if it approaches or exceeds 60, it will not affect those spaceships choosing to buy basic ore in 2779, because in addition to material costs, they also need to consider time costs. , and the risk cost of space travel.”

He Yan drew two question marks on the virtual screen: "These two costs cannot be estimated specifically, but they are also the costs they are least willing to bear."

"That's why they will only choose to purchase basic ore from us." Dali was a little enlightened, but it seemed that he still needed to work on the joint.

"There is a high probability that we will do this." He Yan nodded and put away the virtual display.

In fact, there are still many details that he did not mention. For example, the energy consumed by a cargo spaceship for each curvature leap is a large part of the operating cost. For example, why each spaceship must be fully loaded for the return journey, and some laws of sales psychology. .

A successful sales plan needs to consider the product, environment, psychology and other aspects, and then calculate the optimal solution.

Dali seems to understand but half understands, but he knows that it is meaningless to ask further, he may not be able to digest those profound things by himself.

When he left, Dali seemed to have just remembered something important: "The female father said that the cooperation agreement will be delivered in these two days."

He Yan smiled and said, "No hurry."

After this test, it was Benson who should be anxious.

After sending Dali away, He Yan felt that his ears were too quiet.

He first went to the training room to take a look, only Xiaomi Mi, a worm, closed his eyes facing the floor-to-ceiling windows, and then went to the room to look, and found that Lan Xing was sitting cross-legged on the bed with his back to the door, with long silver hair splashing casually behind.

"Do you want to buy clothes?" He Yan asked standing at the door.

During this time, Lan Xing was wearing his clothes, the trousers and sleeves were a bit short, and he looked a little aggrieved. He thought about buying some new clothes for Lan Xing when he made money.

But after the questioning, Lan Xing ignored him.

This is rare.

He walked behind Lan Xing, wanting to see what the bug was up to, but Lan Xing suddenly turned around and glared at him angrily.

He Yan:?

"What is this?" Lan Xing held a small piece of paper larger than a fingernail, and asked in front of He Yan.

He Yan took a closer look, and it turned out to be the photo of Mir's back in the original photo frame pendant, which he had put in his coat pocket before, and the night he met Lan Xing, Lan Xing wore the coat.

I don't know why, but Lan Xing likes to wear this jacket very much. Every time it dries, he has to take it off and wear it.

Although this photo has been washed several times together with the jacket, it is not damaged in any way because of the special material. The picture in the photo is still very clear. The half of the face of the blond Mir is still smooth and beautiful. The beautiful bug that loses to Blue Star.

"It's a bug named Mir." He Yan was very honest.

Lan Xing narrowed his eyes vigilantly: "Do you know him?"

He Yan thought for a while, the original body came back from the capital planet, and it would be wrong to say that he didn't know the prince of the Zerg race, so he replied seriously: "I know him, but he doesn't know me."

After listening to He Yan's answer, Lan Xing lowered his hand wearily.

He Yan suddenly had an idea: "Do you know him, or remember something?"

Lan Xing glanced down at the photo. When he saw this photo just now, he felt an inexplicable sense of familiarity. His intuition told him that he knew the bug in the photo, but he couldn't capture the picture related to this bug. .

I just vaguely remember that this worm is very popular, even to the point where the worm loves the flowers and sees the flowers bloom.

So He Yan put this photo in his chest pocket, does it mean that He Yan also likes this bug?

Blue Star was hit by a bolt from the blue.

Could this be He Yan's dream lover?

The author has something to say:

Mir: It's great to praise yourself and then eat your own jealousy!
