Ji Donglai did not return home, but went directly to the drone factory, the ultra-long battery life of various drones continued to be spliced, Ji Donglai put on protective clothing and followed until late at night.

From the splicing and assembly of each battery to the later charging, Ji Donglai followed closely, and no step was left behind.

As a boss with a technical background, Ji Donglai is almost obsessed with technology, especially the various breakthroughs made by his company.

"Mr. Ji, we have a by-product sequence development here, which can use all the defective graphene raw materials, and the experiments are all successful, take a look!"

The next morning, Ji Donglai had a simple rest in the office, Jiang Haokun walked into the office with something, Ji Donglai pointed to the seat, and the two sat down.

Jiang Haokun was holding the filter element of a water purifier, which was not large in size, and a layer of flake graphene material was pasted on the expansion body.

Jiang Haokun unplugged the water purifier on the tea table in Ji Donglai's house, replaced the filter element in his hand with the one in his hand, then put the tap water for a while, and then took a sip for Ji Donglai.

"Well, yes, that's what we drank in the Northeast back then. The water in Hebei is too bad to drink, what are you going to do with this thing?"

Tasting the taste of pure water in the water cup, Ji Donglai made a gesture to Jiang Haokun.

"Five-layer filtration, automatic cleaning. Now that people have started to take care of themselves, we are in front of the capital, and there are a large number of start-ups in every office building in the metropolitan area, and few people can afford to drink it every day and a large bucket of water."

"I plan to add graphene elements to our monary technology, pull a big wave of price limits a year ago, and now the entire stock market is maintaining a high level, and it is likely that the stock index will reach 10,000 points this year."

Ji Donglai is very satisfied in his heart, especially when the other party can think of waste utilization as soon as the new technology comes out, and divergent thinking can blossom more, which is rare.

"Installing a high-grade water purifier that can clean automatically can get all the costs back in one year, and we also provide later filter replacement and recycling. The graphene concept is now a big gimmick in the domestic and foreign markets, and we can even export it to Europe and the United States."

Later recycling, synchronous export, group equipment, and relevant units recommend it, which is very complete.

"Then we started to sell graphene water purifiers, and now the technical department has come up with a plan. Generally, the water purifiers on the market are isolation membrane technology, which is actually deceptive. Our graphene water purification technology is multi-layer filtration, which filters out ions."

Jiang Haokun said as he handed over a plan to Ji Donglai, which contained a detailed plan for the water purifier and some of the business plans in it.

"Yes, remember that our water purifiers are mainly high-end, and the low-end market is for those outsiders to do, and we don't dominate the market. You can also consider our other companies, especially the new material company, where they do filtration, and let the people below try to apply for the project, we can fund it, which is very good."

"As long as we do it well, this thing can definitely make a lot of money. In this way, on the one hand, we can use civilian channels to achieve self-sufficiency in our graphene field, and even make profits in the later stage, so as to avoid graphene becoming a burden to other departments, what do you say?"

All new technologies have reached the civilian level to really have a level, and staying in the laboratory is not the ultimate goal.

The military is just to protect the money he earns through civilian means from being taken away, and Ji Donglai has always firmly believed that civilian is the future.

Jiang Haokun wrote down all the meaning of Ji Donglai, and immediately turned around and went to the R&D department.

It is never difficult to open the mold and make the final product in the one-dimensional manufacturing, as long as the leader determines the direction, the R&D department determines the structure.

The remaining departments can be done in a few days, and the design drawings of the water heater at night, even the exterior design, are out.

The shell is too simple to open the mold, the three-dimensional model comes out, and the CNC programming is completed in minutes.

After placing an order to the processing workshop, the new product is processed immediately, and the mold is polished overnight, followed by molding processing.

On the second day, all assembled products were launched, pressure test, effluent test, and large pressure test, all of which were qualified.

Five days later, the batch mold came out, and Jiang Haokun directly proposed the concept of graphene on Yiyuan Technology and sent a customer notice. In an instant, the stock price of Yiyuan Technology soared, hovering over one word, and it was almost difficult to find a vote.

At the appropriate time, Jiang Haokun issued an additional 5 million shares again, and raised almost 20 funds from the market again according to the current price of 350 yuan technology stock price.

The big investors who have been holding one-yuan technology stocks for a long time are happy to bloom at this time, and there has never been a stock in these years that their purse is so bulging. A lot of people have also started to snap up in the market with others, causing the stock price to continue to rise.

At this time, Professor Tu also walked into the Ministry of Science and Technology for the first time, holding the new graphene material that Ji Donglai had sent, and he never had a smile on his face, which was almost the happiest in these years.

Ji Donglai didn't know about it, and he and Jiang Haokun continued to soak in the R&D department, staring intently at the development process of graphene batteries.

Fortunately, each battery has undergone rigorous testing before being assembled into the drone, and the installed battery has zero loss, but the flight speed is limited.

The direct result of this is that the design department of the drone is forced to work overtime every day to re-optimize the structure, and the materials department is chased every day to ask for high-strength materials, and some people are so busy that they can't even eat lunch and dinner.

"Mr. Ji, Dai Fengxian's conditions are too harsh, we still can't reach an agreement for the time being, do you want us to let it go first, now that there are such intensive negotiations, I guess Dai Fengxian thought that we begged him to buy a business."

When the drone was getting better and better, Jiang Haokun found Ji Donglai with the negotiation results of the one-yuan variety show, and according to the latest negotiation results, Dai Fengxian asked to buy at least 10% of the shares of the one-yuan variety show.

It took five years to complete the operation and profitability of the independent film and television division, and as for the additional share premium between 10 percent and 3 percent, the other party did not want to pay a dime.

Hu Xinyu did not let go, and the two families are now deadlocked.

"Then let's put it first, there's no need for this one buyer. Now there are a lot of people who do film and television in China, look for them and see if anyone is interested, limited to Hollywood experience and Hong Kong government experience."

"In the past few years, there have been a lot of high-quality Hong Kong filmmakers who have gone north, so it's a big deal that we find these operations and invest in them ourselves. With the new graphene concept, we can still raise money by issuing some new shares."
