A courtyard house; Li Yunlong, a subordinate of the deputy director of Harbin Military Engineering I

Upon hearing the names "Old Chen" and "Commander Zhang," Brigade Commander Chen chuckled inwardly: Brilliant! Absolutely brilliant! This is exactly what I want my subordinates to know: the corps knows only Zhang, not Chen. This way, entrusting them with their duties will be even more logical. I must train Zhang to be the best beast of burden in the universe. Only when the Third Corps is completely under Zhang's control can I, Chen, accomplish even greater things... Hahaha!

At this moment, for Commander Chen, who was always observant and meticulous, what Zhao Gang was cricketing about was unimportant.

The important thing is that even without me, Chen, the Third Army Corps can be united as one, and after entering Korea, it will surely be invincible!

Zhang Renfeng observed Zhao Gang's distracted expression, then looked at Old Chen's sly smile, and considered Zhao Gang's earlier address to Chen and his own, before noticing Old Chen's reaction.

He cursed inwardly, "Does the old man really think I'm some kind of nuclear-powered donkey?" Whatever, it's his fault for being in poor health. Maybe I can help him out, and with his optimistic spirit, he'll live to be seventy or eighty, then I can use him to command others!

Although he didn't know that in just a few minutes, Zhao Gang's thoughts had expanded to the heavens...

They even harbored rebellious intentions, attempting to substitute one thing for another.

"Gentlemen, those are the gun carriages!" Zhang Renfeng said.

He had long since come to terms with the question of whether he would be a perennial runner-up. Being runner-up was fine, but he had to be clear about who he was going to be. Being runner-up for Commander Chen was practically a blue ocean.

These were brought over from other factories. When the soldiers heard that their commander wanted to see the artillery, they rushed over! Some used horses, and some used jeeps to pull them.

The 15th Army was very adept at this; Chen's shrewdness and Zhang's decisiveness were evident in every aspect, from top to bottom.

It looks refreshing and delightful!

Director Nie visited his son-in-law's two armies. One, Li Yunlong's unit, was particularly interesting. The commander was hot-tempered yet possessed a wild spirit. A defensive force with such a commander was the kind of general capable of achieving extraordinary feats. The unit was united, the political commissar was gentle, the deputy commander was knowledgeable and tactful, and the chief of staff was also capable of fighting tough battles. Especially noteworthy was the Liangshan Special Forces, directly under the command of Deputy Commander Xing and Chief of Staff, which was crucial to the entire army and even the entire corps. This well-equipped and battle-hardened force was, in fact, the elite force that my son-in-law had strongly advocated for its formation—brilliant!

Looking at the 15th Army, Qin Jiwei immediately exudes the aura of a general. Although he is relatively inexperienced, the entire army is in high spirits and well-equipped, making it a main force and a ballast stone for defeating the enemy.

Looking at Commander Chen's boundless tolerance and trust in my son-in-law, it's utter nonsense to say that the Third Army Corps was poorly coordinated due to its temporary formation.

Haha, no matter what... he's still my son-in-law. The 19th and 3rd Corps that were sent this time are also my old Nie's fresh troops. I, old Nie, have a good eye for people, and my judgment of people is generally not wrong!

After returning to Beijing, I will naturally advise the Legion Commander on the full-scale expansion of the 107mm rocket launcher in all major arsenals!

His gaze returned to the gun mount that had just been pulled over...

The gun carriages have wheels and handles at the bottom, so they can be pulled by mules or horses, or by jeeps.

The twelve cannon barrels were bundled together side by side, simple to the point of being rudimentary, and every weld point exuded a pragmatic style.

Only Brigade Commander Chen, who also came from the Second Field Army, knew that this was the style of the Taihang Mountain troops, full of calculations. Even in their 386th Brigade, if they didn't have thick skin, could they have a good life?

That's definitely not possible!

If you don't go to your superiors to smoke, and you don't go to the old political commissar to drink, well, if you don't have a cotton-padded coat, go to the logistics department. If they don't have this or that, they'll have to rob a bunch of teachers and officers.

If all else fails, just see which of your subordinates is wealthy, give them a call, and congratulations on your fortune...

The legion commander looked at the cannon's base and immediately became interested. With the keen insight of a strategist, he quickly noticed the cannon's unusual features.

"This cannon, how come it's so small? 1, 2, 3... twelve barrels???"

"A 12-barrel salvo means 12 shells in one round, which is more than 100 shells for a squad, and more than 1,000 shells for a regiment... Goodness."

He even acted as a mule, trying to pull it from the front, but found that it was too small for him to pull on his own, so he called Director Nie and Zhao Gang to help push it from behind.

The legion commander was as happy as a child, "Wow, I can actually pull it... Damn it, I can actually pull it!! How heavy is this thing?"

He straightened up and patted the crossbeam on the gun mount as if he were patting his own child's head.

Zhang Renfeng gestured to Lao Cao, who explained, "The total weight for marching is 385 kilograms, and the total weight for combat is 613 kilograms."

After finishing his sentence, Cao Huali added, "This is without any weight reduction. If we continue to optimize the materials, the total weight can be reduced even further."

Brigade Commander Chen was excited. After all, he had studied in the Soviet Union, under the Cheka, so his intelligence work was top-notch. He said...

"This is somewhat similar to the Katyusha rocket launcher. The Katyusha rocket launcher weighs 6.8 tons, which is 11 times the weight of this rocket launcher. Each shell weighs 42.5 kilograms, which is not conducive to mountain warfare and deployment. But this 107mm rocket launcher can."

He walked around the gun carriage, leaning on his cane, and became more and more satisfied with what he saw.

"The Katyusha is good, but it's too heavy. We have to build a makeshift bridge to cross it, and it's impossible to travel on mountain roads."

Our 107 can be disassembled and carried by the soldiers. It's no problem to cross mountains and valleys. Once we get there, we can assemble it and start fighting.

The Americans never dreamed that we could spray them in the face with rockets from what they thought was an absolutely safe distance.

The design concept of this thing is naturally in line with the combat style of the Chinese People's Volunteer Army—lightweight, flexible, powerful, and able to hit and run.

He crouched down to examine the wheels at the bottom of the gun carriage, then looked up at Zhang Renfeng. "How long have you been accumulating this thing? Since the Taihang Mountains, haven't you?"

Zhang Renfeng didn't respond to that, thinking to himself that it wasn't just the Taihang Mountains; the design blueprints for that thing had been in his mind for two lifetimes.

Some things can't be rushed; they can only be implemented when the industrial base reaches a certain level.

Even now, if you maximize production, the output is still very limited.

The cannon barrels he tinkered were all seamless steel pipes that Zhang Wanhe had gotten for him.

Fortunately, he had capable people like Cao Huali under his command. They worked on everything from materials to craftsmanship, and finally managed to assemble the first batch of prototype cannons before entering the capital.

Once they arrived in North Korea, this thing, combined with Li Yunlong's Liangshan assault team, could be divided into small groups and infiltrated behind enemy lines, extending firepower eight kilometers forward... The more he thought about it, the more he felt that this was a promising opportunity.

Moreover, besides these things, Zhang Renfeng also planted quite a few time bombs...

Regarding the range, Zhang Renfeng said that it is normally comparable to Katyusha, but if an extended-range missile is used, the maximum range can reach 15 kilometers.

"The standard range is eight kilometers, similar to what was demonstrated today. The extended-range version uses a different propellant formula and can reach fifteen kilometers. However, the cost is higher. We will prioritize the production capacity of the standard version, and discuss the extended-range version later."

"A gun crew consists of four people: two carry the shells, one carries the gun barrel, and one carries the aiming device and accessories. They can set up and fire in three minutes once they arrive at the location. After firing, they can retreat in one minute, pick up their guns, and run. Even if the US military's artillery reconnaissance radar locks onto their position, by the time they react, we've already crossed two hills."

Seeing how excited Director Nie and the legion commander were, Zhang Renfeng knew he had to let them have their fun.

He waved to the pillar, "Go, load those twelve tubes of ammunition and let the leaders operate them themselves."

Then, Zhu Zi guided them in a salvo, aiming at a hillside 8 kilometers away, using high-explosive shells!

Zhu Zi deftly led several engineers to load twelve shells into the cannon barrel, checked the circuit connections again, then stepped aside and handed the ignition switch to the corps commander.

The legion commander's hand trembled slightly as he took the switch, but he couldn't suppress the smile on his face. "Let me do it?"

He glanced back at Director Nie, who nodded at him. "If you're coming, then come. You're about to come out of seclusion. This was developed by Renfeng. I can do whatever I want with it."

The legion commander was annoyed; this old Nie was really something... But he still took a deep breath and pressed the ignition switch.

Boom! Boom! Boom! Boom! Boom! Boom! Boom! Boom! Boom! Boom! Boom! Boom!

Twelve 107mm rockets were ignited in sequence, their tails spewing out blazing white flames. The rockets trailed plumes of white smoke as they flew out of the barrel, tracing twelve parallel paths across the gray sky, like a giant broom sweeping across the heavens.

The glow of the tail flames reflected on everyone's faces, and that moment of firelight gave everyone's expressions a warm hue.

The sound shook the ground slightly, and the air was filled with the pungent smell of gunpowder, but no one retreated. They all looked up and followed the trajectory of the shells.

The twelve shells landed almost simultaneously, and a burst of fire erupted on the hillside eight kilometers away.

The sound of explosions echoed back continuously, muffled thuds, one after another, like distant rolling thunder.

Dust and gravel rose up, and the smoke gradually merged into one, instantly covering the hillside with a layer of hazy dust.

When everyone arrived at the eight-kilometer site, they were all shocked by the results.

When they reached the point of impact, everyone fell silent.

The hillside, which was originally covered with withered grass and low shrubs, is now unrecognizable—twelve bomb craters are scattered around, each more than two meters wide and half a meter deep. The soil around the craters has been turned up and is scorched black, with gravel flying dozens of meters away.

The area between the craters was densely covered with shrapnel from the explosion, and the ground was turned upside down as if it had been plowed.

If these twelve shells were to land on the enemy's marching column or assembly position, the destructive effect would be unimaginable.

The corps commander squatted down, reached out and pinched a handful of scorched earth from the edge of the shell crater, rubbed it between his fingers, then stood up and looked at the distribution of the entire impact zone. His eyes held the precise judgment of an old soldier regarding the effectiveness of firepower.

Wow, that's amazing!

He turned around and looked at Zhang Renfeng; this time, even he couldn't hold back anymore...

Honestly, this 107mm rocket launcher is a bit unreasonable. If this thing were to be mass-produced, it would be a huge boost to our army, which is good at mobile warfare. But what about the enemy?

That was a fucking nightmare!!

Based solely on the contribution of these rocket launchers, Zhang Renfeng deserves the title of "General of Demolition"! With demolition capabilities, why would I need the Whirlwind?
