Bright Sword: Starting from the Improved Grenade

When Zhao Tianyang drove the tractor slowly back to Huangya Cave, it was already dark.

"Chief, you're back!"

As soon as Zhao Tianyang got off the tractor, Li Yuncai ran over happily.

"Dinner has been prepared for you and is on the desk in your room."

"Thank you!"

After waving his hand to express his gratitude, Zhao Tianyang returned to the tent and ate a bowl of corn paste and two steamed buns on the table.

He came to Shen Hong's tent, saw that the light was still on inside, and immediately shouted in a low voice.

"Is Comrade Shen Hong asleep?"

"Not yet! If you have anything to say, come in and tell me."

Hearing Shen Hong's voice, Zhao Tianyang lifted the door curtain and walked in.

I saw Shen Hong lying on the desk, concentrating on drawing the blueprint.

"What are you busy with? Why are you so focused?"

“Design of a large stamping press.”

Shen Hong explained without even looking up: "Two weeks ago, you said you wanted a punch press to make a light machine gun. I plan to design a three-ton one!"

"Really!"

Zhao Tianyang became interested and ran behind him to look at the drawings on the table.

Seeing that the drawing was densely covered with diagrams and data, he couldn't help but ask, "Is this the mechanical, multi-process continuous punching machine you mentioned?"

"Yes, because it has to generate a force of 30,000N, the design is more complicated."

Shen Hong nodded.

"So how long will it take to see the finished product?"

Zhao Tianyang asked.

"It's almost done. In two or three days, after I calculate the data, it will probably take half a month to manufacture it."

Shen Hong calculated the time and answered.

"Half a month? Looks like I need to finish all the preliminary work first to avoid wasting time!"

Zhao Tianyang thought secretly.

"Okay, then you go ahead and do your work. I'll go back and rest."

"it is good!"

Back in his tent, Zhao Tianyang took out a few drawings and looked at them.

"Light machine guns require high carbon steel, spring steel, low carbon steel, and walnut."

"Heavy machine guns require stainless steel, mild steel, ................."

After quickly finishing the materials needed for the preliminary preparation, Zhao Tianyang turned off the lights and went to sleep.

If nothing unexpected happens, he will be busy with these things in the next few weeks.

...........

Yan'an.

"There's news!"

In a dim room, an elegant man ran in excitedly with a telegram.

"Comrade Xiuquan sent a telegram saying that the Soviet Union has agreed to trade aluminum ore and rubber with us."

"Great."

The majestic man smiled and said, "That's great! It's a pity that the boss left yesterday, otherwise he would definitely be very happy to hear this news!"

"Ah."

The elegant man nodded, then revealed a hint of difficulty: "It's just that transportation is a little difficult. We need a lot of aluminum ore and rubber."

"The Soviets proposed that they could send us rubber via trucks from their country."

"As for aluminum ore, it's mined locally in Xinjiang, where they have several small mines."

"Is it the Altai region of Xinjiang?"

The majestic man was moved and said, "There is intelligence that the Soviets have discovered incredible minerals there!"

"Yes, the Altai region is rich in mineral resources. The Soviets sent people there in 1935."

The elegant man echoed.

"Do you think it's possible for the Soviet Union to help us build a few mines there?"

The majestic man thought for a moment and asked.

"this........."

The elegant man thought for a moment and said, "It's a little difficult, but if we cooperate, it should be possible."

"Then talk to them. We didn't develop with them before because we didn't have the confidence."

"It's different now. With Comrade Zhao Tianyang here, we are fully capable of transporting the excavated ore back from Xinjiang."

The majestic man said firmly.

"Okay, I'll send a telegram to Comrade Xiuquan right away."
