Su Su was busy watching movies and chasing dramas, and Su Su, who had never been in contact with film and television dramas, was completely conquered, crying for the love, hatred, and hatred in the play.

Shi Han is busy optimizing the communicator to make it lighter and more suitable for use in battle.

On this day, Shi Han was busy in the laboratory when he received news that Yang Lan was looking for him.

There was no nonsense when they met, and Shi Han knew that he must have encountered a problem.

"Team Leader Yang, what is the problem?"

"Commander Shi, there is a serious shortage of raw materials in our production workshop, and we will stop work before the next beast tide."

"So fast?" Shi Han was surprised.

After the beast tide in November, the Chuanhu base still maintained its usual transaction with Dawn City, hiding everything that happened from Dawn City. At the same time, in order not to arouse their suspicion, they did not dare to increase the trading volume of raw materials.

However, it was originally expected that if all the inventory materials in the base were processed, it should be enough for the Yunying No. 1 prototype to be released.

"All that Yunying 1 needs is special materials. The consumption of raw materials exceeded expectations. We simply don't have enough stock, and if we don't want to slow down the progress, we have to think about how to get more materials now. ”

Shi Han thought for a moment, and he said, "I'll figure out how to deal with the raw materials, do you have any other questions?" ”

"No, we're on good tracks."

Sending Yang Lan away, Shi Han fell into a short period of contemplation. After the 2039 tsunami, 80 percent of developed cities will be submerged in the sea. Coupled with the corrosion of acid rain over the centuries, scrap metal and other artificial materials left over from the past have been depleted.

It's hard to find a piece of rusted iron from the wasteland right now. The materials that come in from Dawn City each month are only a few tons. These materials have been processed, and the last thing that can be used is only a few hundred catties, and these basically have to produce rifle ammunition for Dawn City. Therefore, the materials of the Chuanhu base have always been in short supply.

Now there are only two ways, one is to increase the volume of transactions from Dawn City, which must have a lot of inventory. The second is to send a field team to search for it.

Increasing trading volume from Dawn City first considers whether Dawn City will agree to increase trading volume. Secondly, Dawn City will definitely ask about the reason and R&D progress, and if you are not careful, you will expose the information that the Chuanhu base has gone out of control, and if you can't say it, you will go to war directly!

So I can only rely on the base itself to figure it out. Shi Han slowly looked at the soles of his feet, of course he didn't want to mine, and now there are probably no mines in the world. He thought of the mountain city!

The reason why the Chuanhu base is called the Chuanhu base is because it is built on the edge of the Chuanhu Lake! And Chuanhu is the original Sichuan-Shu Basin, the tsunami and sea level rise have turned the Sichuan-Shu Basin into a huge inland lake, which is Chuanhu!

More than 100 kilometers away from the base, under the water surface, is the mountain city! Or under the water surface less than 100 kilometers north of the base is Lucheng! Only in the ruins of the cities of the Old World can there be enough raw materials.

Shi Han walked to the window and looked at the base, which was already covered with snow. At this time, the lake should have frozen! Every year, there are several months of ice in the lake.

Shi Han dared to hit the bottom of the Sichuan Lake this time, mainly because of it!

"O dragon! It's up to you whether you can get the materials from the mountain castle or not! ”

The next step is to prepare the ice digging equipment, diving equipment, sling equipment, transportation equipment, and necessary guards.

During the freezing period of Sichuan Lake, there is a forbidden land on the lake, and there is no food or drinking water for tens of thousands of square kilometers of curling, and no life will set foot on it.

There will be no large creatures under the ice, and amphibians such as dragon pythons, gold and silver pythons, sawtooth crocodiles, and tortoises will leave the lake before freezing, and the most dangerous under the surface of the water should be large fish such as saber-toothed fish, hummers, and mutated mullets.

And the little dragon python dragon is the natural enemy of these underwater creatures, so there is a certain guarantee in terms of safety, and Shi Han will not rush to death.

"You're going to explore Lake River? Are you serious? Wu Han looked at Shi Han in surprise, no one had ever dared to think of exploring Sichuan Lake.

"Yes! We are now in a position to explore the lake, and we must seize the opportunity of the ice period of the lake. Shi Han said while eating, now that the teacher is gone, there are only two people at home, Wu Han and him, and he will take time to come back for lunch every day when he is busy.

Wu Han slowly chewed the food in her mouth, and she suddenly said, "I'm going with you!" ”

Shi Han looked up at Wu Han with a serious face, and he said with a smile: "What are you doing, this is just a normal exploration, there is no risk." ”

Wu Han still insisted, "Since there is no risk, what happened to me going with me?" ”

Shi Han thought for a while and said, "There are no women in the exploration team, it's inconvenient for you to go!" "On the endless ice lake, if nothing else, what are you going to do? You can't bring a portable toilet for a woman, right?

"No women? Su Su is not going either? ”

Shi Han was stunned, he seemed to understand something, he raised his hand and rubbed Wu Han's head, and said with a smile: "Of course you won't go!" This is not a combat mission, and she is going to be in Red Rock! ”

Wu Han enjoyed Shi Han's spoiling, and she immediately said happily: "Okay, I won't go, I'll sit at the base!" ”

In the past, Shi Han threw himself into the laboratory, and he always avoided her, although he was in the base, he couldn't come back a few times a year. Shi Han is obviously more cheerful and sunny now, which makes her very happy. The main thing is that Shi Han accepted her!

Shi Han looked at Wu Han's eyes and said seriously: "Don't think about it too much, Crispy and I are normal comrades-in-arms, but you are different!" ”

Wu Han chewed mechanically in his mouth and asked, "What's the difference?" ”

"You're my girlfriend! I'll marry you! Shi Han seriously confirmed the relationship between the two for the first time. Although the two have made their relationship clear before, it has always been a natural tacit understanding, but they have never said it so positively and formally.

Since the completion of the geomagnetic gravitational confinement experiment, Shi Han has let go of all his burdens, and later experienced life and death and so many twists and turns. So he can now face Wu Han's feelings and dare to give her a lifelong commitment.

Wu Han felt numb in his heart, he had never been so happy.

Wu Han's careful thinking was punctured, and she got Shi Han's promise again, she coquettishly leaned on Shi Han's shoulder and twisted a few times, and said, "Then you are still crispy, crispy and affectionate." ”

Shi Han was stunned for a moment, and said blankly: "Her name is crispy!" Otherwise, what do I call her? ”

Wu Han was also stunned, he didn't even know her name! I was immediately relieved. "Don't you know her name is Su Su? Su in Suzhou, a millet planted in spring? ”
