A magazine of 30,000 rounds, you call it Hanyang

Li Yunlong nodded.

He knew how terrifying the combat effectiveness of the Fourth Battalion was. Take this battle for example, the entire Japanese brigade in Liujiaao was wiped out by Zheng Kaixuan and the Fourth Battalion.

"Kaixuan, if your Fourth Battalion ever collapses, please be sure to let me know. No matter how difficult the situation, I will definitely send troops to support you."

Zheng Kaixuan smiled confidently.

"Don't worry, Commander. The Fourth Battalion won't embarrass you. The Japs are just unlucky to have run into our Fourth Battalion. It's unfortunate for them."

"Hahahaha!"

Everyone burst into laughter.

When everyone thinks back carefully, it seems to be true. Every time the Japanese encounter the Fourth Battalion, they basically have bad luck, bad luck! Bad luck!

"Brother Kaixuan, I want to ask you for a favor."

Wang Chengzhu walked in from outside. Zheng Kaixuan actually didn't even notice when Wang Chengzhu had just gone out.

"Zhu Zi, we are all brothers. There is no need to ask for anything. If you have something to say, just say it directly."

Wang Chengzhu scratched his head a little embarrassedly.

"Well, I just went to see those four-barrel mortars of yours. They're really advanced. Let's discuss whether you can give me one."

The four-barrel mortar, also known as the sixth-level Triumph mortar, is currently being used by Yang Wanli's artillery unit of the third company of the fourth battalion.

When the battle in the canyon just started, it was Yang Wanli who led his men to use these three mortars to bombard the Japanese infantry company, rescuing Li Yunlong and others.

The terrifying power of the artillery explosion, the rapid firing frequency and speed, are still fresh in Wang Chengzhu's memory.

Wang Chengzhu was thinking about this matter while he was having dinner. He quietly ran out to find Yang Wanli and carefully observed the Triumph mortar.

The more he watched, the more he liked it, and he was almost obsessed with it.

He liked this modified mortar so much that he couldn't help but ask Zheng Kaixuan for it.

"Zhu Zi, don't be too greedy. Two infantry guns, five mortars, and more than thirty grenade launchers, aren't they enough for you?"

Even Li Yunlong felt a little embarrassed.

Zheng Kaixuan was very generous this time and left almost all the spoils to them. It was really a bit too much for Zhuzi to ask for the mortars that the Fourth Battalion was using.

"Captain, you don't know that two infantry guns plus five mortars might not be as powerful as the modified Triumphal gun. I'd rather not have those seven guns..."

Li Yunlong's curiosity was immediately aroused.

"Old Li is not well educated, so don't lie to me."

Then, Li Yunlong turned his gaze to Zheng Kaixuan.

"Triumph, is your modified mortar really that powerful?"

Zheng Kaixuan did not answer directly. He asked a soldier beside him to run out quickly and get a shell.

He held the shell in his palm and motioned Li Yunlong and others to watch.

Li Yunlong's eyes widened in surprise.

"It's so big, are you sure it's a mortar shell?"

Zheng Kaixuan nodded, then gently put down the shell, then walked to Wang Chengzhu and patted Wang Chengzhu on the shoulder.

"Zhu Zi, it's not that I don't want to give it to you, but I'm asking you, can you make this type of shell?"

Wang Chengzhu was immediately dumbfounded.

He's good at firing cannons, but asking him to rub the cannonballs with his hands? He wouldn't dare, as that would be like asking for too much luck.

Looking at Wang Chengzhu shaking his head like a rattle, Zheng Kaixuan laughed.

"That's it. If I can't produce any shells, what do you want my cannon for? It's useless even if you take it."

Li Yunlong also agreed with this and nodded.

Zheng Kaixuan finally breathed a sigh of relief. Fortunately, Lao Li didn't see what his modified mortar looked like. Otherwise, with Lao Li's temper, he would have taken one away from him at least.

It’s not that he was reluctant to give it, the key point is that he didn’t even have enough artillery shells in his hands to squander, and he really couldn’t use them if the regiment took them away.

Li Yunlong and the regiment headquarters have enough spoils of war from the Japanese battalion headquarters today. Even if they encounter Japanese battalion-level troops next time, they may not suffer any losses.

"Report, the Second Battalion Commander is here."

At this moment, a soldier from the Fourth Battalion who was on guard outside ran in quickly.

Zheng Kaixuan nodded at him, and the soldier turned and walked out.

"Damn it! How dare that little bastard Shen Quan come here! My brothers and I have been trapped here for a whole night, where has he been?!"

When it comes to Shen Quan, Li Yunlong becomes furious.

However, after seeing two people covered in mud and ragged clothes walking into the tent from outside, Li Yunlong's anger instantly disappeared.

"Captain, you and your men didn't return until the early morning, so Gensheng and I set out immediately. Unexpectedly, we encountered a powerful enemy force on the road. After a fierce battle for half a day, we were forced to take a detour and go in a big circle..."

The people who came in were the Second Battalion Commander Shen Quan and Deputy Battalion Commander Wang Gensheng.

"Captain, are you okay?"

Wang Gensheng also walked up quickly and shook Li Yunlong's hand.

"I'm fine, what the hell could possibly happen? The devils who can kill me, Li Yunlong, haven't been born yet! Haha!"

After learning the reason why Shen Quan and the Second Battalion were late, Li Yunlong's anger subsided and he burst into laughter.

Wang Gensheng was also one of the veterans who followed Li Yunlong from the Red Fourth Front Army to the Northwest.

When he was in the 772nd Regiment, he was very good at throwing grenades and was noticed by the deputy regiment commander. He became the model grenade thrower of the entire regiment.

It was not until a few days ago that Li Yunlong called Wang Gensheng back from the 772nd Regiment and appointed him as the deputy battalion commander of the Second Battalion of the New First Regiment.

"Captain, how did you take down the Japanese battalion headquarters?"

Shen Quan and Wang Gensheng were both surprised.

"This is all thanks to Kaixuan..." Li Yunlong replied.

Zheng Kaixuan waved his hand.

"Alright, Commander, now that the Second Battalion Commander is here, we should withdraw. We can't stay here overnight, or we'll have trouble."

Everyone quickly raised their heads to look at the sky outside the tent. It was already afternoon, and the snow was a little lighter. The days were short in winter, so it wouldn't be long before it got dark.

"Okay, Kaixuan, you must be careful on your way back to Weizhuang. We have to get back as soon as possible. If the brigade commander finds out that I'm not at the regiment headquarters, he'll probably be furious again."

Li Yunlong led his team away, and Zheng Kaixuan and the soldiers of the Fourth Battalion did not stay any longer.

Zheng Kaixuan did gain something from the battle of Liujiaao this time.

In addition to rescuing Li Yunlong and obtaining more than 300 epaulettes, he also obtained five vehicles.

To be precise, there are five cars, one large and four small.

The big one was a military truck with a huge front and a cargo bed with iron fences welded on all four sides.

This type of military truck has extremely strong off-road capabilities and is an excellent tool for transporting supplies and ammunition.

The four smaller ones were the Japanese's three-wheeled motorcycles with sidecars.

Originally, Zheng Kaixuan didn't expect that there would be vehicles in the Japanese brigade headquarters in Liujiaao.

His Triumph mortar, Triumph grenade and Hanyang fully automatic rifle have all reached level ten. He now has six captain's epaulettes, which means he can upgrade his weapons to level eleven.

Just after the battle, when Zheng Kaixuan was about to upgrade his weapon, he received a prompt from the system.

To upgrade to level 11, you need to use the Japanese motorcycle as an auxiliary material.
