Bright Sword: Starting from the Improved Grenade

Yan'an.

"The New Fourth Army has reported that it has successfully arrived in Changzhi, Shanxi."

In the room, the elegant man held the telegram in his hand and preached to everyone present.

"Haha, after we gave them the order to move north in January, they were besieged by seven KMT divisions in Jing County. I thought they wouldn't be able to arrive on time!"

The majestic man looked at the telegram and said to everyone with a smile.

"Unjust is doomed to destruction!"

The man with glasses snorted, "Do they think it was a year ago?"

"When their seven divisions saw our bombers and gliders coming to support them, they were so frightened that they fled in all directions and had no time to encircle and suppress the New Fourth Army."

"Okay, let's not talk about them anymore."

The dignified man waved his hand and said, "Now that the New Fourth Army is in place, it's time to start the process of retaking Shanxi."

"Why don't you wait any longer?"

At this time, someone hesitated and said, "The armored division has not yet completed its training. They haven't even got half of their weapons and equipment."

"Need not!"

The dignified man simply said: "We don't need them this time. Our infantry and air force are enough to recapture Shanxi!"

"Okay, I'll send telegrams to the various ministries right away, asking them to come to Yan'an for a meeting."

Semiconductor laboratory.

"Minister, this is what was designed according to your drawings!"

Luo Peilin placed a seven-centimeter-long metal tool in Zhao Tianyang's hand. "Is this the proximity fuse?"

As for the proximity fuse, Zhao Tianyang wanted to make it when he got the 88 gun.

However, although the principle of the proximity fuze is simple, it is nothing more than using the shell as an antenna and a vacuum tube radio wave transmitter inside.

After being powered on, it emits radio waves of 180 to 220 MHz. When the projectile approaches a reflective object, part of the radio waves are reflected.

As the distance between the shell and the target decreases, due to the Doppler effect, when the signal strength exceeds a certain limit, the shell can be detonated.

But the difficulty lies in the fact that the entire device must be able to withstand more than 2 times the acceleration of the earth's gravity when fired by artillery.

And spin five hundred times per second, while being small enough to fit inside the warhead of a cannonball.

With the semiconductor technology they had at the time, it was simply impossible.

Now with the help of the Germans, their semiconductor technology has skyrocketed and they have finally made this little thing.

"Let's go, let's give it a try!"

Zhao Tianyang took the proximity fuse and came to the cannon factory and found Gong Jiahong.

"Minister, is there something going on here?"

"Ok!"

Zhao Tianyang nodded and handed the proximity fuse to Gong Jiahong.

"This fuse can be installed on an 82mm mortar shell. Try it out."

"Remember, the experimental site should have few people and the experimental personnel should be reliable!"

"Yes!"

Looking at the fuse in his hand, Gong Jiahong's heart trembled and he became extremely alert.

Soon, a training ground under martial law was prepared by the security team of the Artillery Factory.

Gong Jiahong personally installed the special fuse on an 82mm artillery shell.

"The Minister is ready!"

"Adjust the parameters so the shells land ten centimeters from the target!"

Zhao Tianyang took out a telescope and gave instructions.

"it is good."

Gong Jiahong came to the Taihang Type 82 mortar and began to adjust it.

A moment later, the 82mm mortar shell was fired by Gong Jiahong.

With a loud "bang", the 82mm mortar shell soared into the sky and hit the target directly.

"boom."

There was another loud bang, and the target was blown to pieces.

"Something's wrong!"

Gong Jiahong looked at the target that was shattered in the air not far away in surprise: "Why does this howitzer feel like it exploded in mid-air?"

"You read that right!"

Zhao Tianyang crawled out of the explosion-proof pit: "This is our latest developed proximity fuse."

"It is different from impact fuses and time-delay fuses. It can detonate bombs at a distance of tens of centimeters or meters by relying on radio waves."

"I see!"

Gong Jiahong suddenly realized, "I was wondering why I didn't see the explosion pit at the scheduled landing point! It turns out it really exploded in mid-air!"

"Remember, the information about the proximity fuse must be kept strictly confidential."

Zhao Tianyang looked at Gong Jiahong and said seriously, "Next, I will give you the detailed information of this fuse. After receiving the information, I will immediately organize people to produce it."

"Yes."

Gong Jiahong quickly assured: "Minister, don't worry, I will set up a separate factory to specialize in the production of proximity fuses."

"That's good."

After leaving the Cannon Factory, Zhao Tianyang returned to the Semiconductor Laboratory.

Now that the proximity fuse is out, the next natural step is to study the fire control radar.

.............

June 1941, 6, the weather is sunny.

Germany tore up the Soviet-German Non-Aggression Pact and suddenly launched a blitzkrieg against the Soviet Union.

Relying on surprise attacks and their equipment advantage, Germany advanced straight into the enemy territory and defeated the Soviet army. Once the news came out, it shocked China and the world.

The Japanese soldiers felt inexplicably excited and encouraged, thinking that as a fellow Axis power, they could do what Germany could do.

So a proposal to attack Pearl Harbor and conquer Southeast Asia was put on the table and discussed at the Imperial Conference.

"Since 1915, the United Kingdom, the United States and other countries have been eyeing us and trying to seize our Asian market."

"In 1922, the United States took the lead in proposing the so-called Four-Power Treaty, the Naval Arms Limitation Treaty, the Nine-Power Treaty and other treaties in Washington that seriously infringed upon the interests of the Empire of Japan."

Tojo looked at the imperial executives present and gave an impassioned speech.

"Now the United States not only accuses us of violating the Nine-Power Treaty and the Kellogg-War Pact, but also imposes a tough military embargo on us."

"In order to defeat us, they shamelessly offered assistance to China and sent pilots!"

"There is an old Chinese saying, 'What can be tolerated? What cannot be tolerated?' The Americans are about to shit on our heads. Can you still tolerate it?"

"Ok!"

The Fishman Emperor sitting above nodded with emotion.

Yes! For the sake of the Greater Japanese Empire Co-Prosperity Sphere, he was reluctant to eat, reluctant to wear, and even the fence outside the house was dismantled to make guns. Is it easy for him?

The Americans actually dare to make trouble!!

It’s really terrible!

"His Majesty!"

At this time, the Konoe Devil said to the Fishman Emperor: "Since 1937, all countries have practiced trade protectionism."

"Our domestic resources are increasingly scarce. After launching a full-scale war, our steel, gasoline, and food prices have dropped to the red line."

"The country is in turmoil now, and the troops in China are stuck in a dilemma. I think it's time to look for new opportunities."

"Ok!"

The Fishman Emperor smiled and nodded. It’s time to gamble on the country’s destiny again. I’m the best at this.

Soon, a policy entitled "Outline of the Imperial National Policy to Adapt to the Evolution of the Situation" was passed by the Imperial Conference.

Japan officially abandoned its "Northward Advance Policy" and began to deploy troops to fully implement its "Southward Advance Policy."
