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

The man's surname is Liu, and his name is Liu Daqiang. He is in his thirties.

After learning about his identity and experience during the conversation, Zheng Kaixuan was filled with awe.

This person has studied abroad and is a top coal mine engineer!

After the mining area fell, the Japanese paid special attention to him and treated him like a guest of honor.

Liu Daqiang refused at first, but in order to survive, he had to pretend to agree and deal with the Japanese.

But when he saw thousands and thousands of innocent people dying tragically in the mines and watched the endless stream of resources like mountains being transported away by the Japanese, Liu Daqiang's heart was bleeding.

So, he secretly used some very covert means to trip up the Japanese in the mine.

Many machines would malfunction from time to time after passing through his hands.

However, these are just some small tricks and cannot cause much damage to the Japanese.

What Liu Daqiang wanted to do most was to blow up the coal mine and make the Japanese lose everything.

But he is just an ordinary person, he simply can't do it.

But he did not give up and kept working towards this goal.

Taking advantage of his position as an engineer, Liu Daqiang spent several months quietly drawing a map of the entire mining area.

He felt that this map would be of great use in the future.

Then, he began to think of ways to escape from the mine, and then send the map to the Eighth Route Army and other anti-Japanese armed forces, in order to destroy the coal mine and inflict heavy damage on the devils!

Liu Daqiang can truly be said to be both wise and brave.

He escaped alone from the heavily guarded Japanese mining area, avoiding layers of patrols, crossing the wall and electric fence, and then crossing two barbed wire fences and three trenches, and actually escaped.

Of course, his body was covered with scratches during this process.

As soon as he got outside and had no time to catch his breath, he was met by several Japanese soldiers who were patrolling outside the mining area.

If he had not met Zheng Kaixuan by chance, he would have died from excessive blood loss even if he had not been captured by the Japanese.

"Commander, I will hand this map to you, and I will die without regrets."

Liu Daqiang took out the map from his arms tremblingly and handed it to Zheng Kaixuan.

It can be seen that he cherishes this map very much and protects it with his life.

His body was covered with bruises and tears from the barbed wire, and his clothes were shredded into strips, but the map was surprisingly intact!

This map clearly marks the locations of the Japanese garrisons throughout the mining area.

The specific buildings, functions and features of each area are marked.

This map is not completely accurate, but it is pretty close.

It can be seen from the map that the location that Zheng Kaixuan and the Fifth Battalion had just discovered was actually just a place where the mining police team was stationed in a mine, and did not belong to the main force of the Japanese devils.

The real main force of the Japanese devils was located in the opposite position.

The Japanese built thirteen artillery towers in this mining area, and the specific location of each artillery tower was clearly marked.

This map is undoubtedly a timely help for Zheng Kaixuan.

"Old Liu, you have really helped me a lot!"

Zheng Kaixuan excitedly held Liu Daqiang's hand.

"Well, you rest for a while. I'll familiarize everyone with the map, and then we'll start preparing for battle right away."

Liu Daqiang lost a lot of blood, his lips turned purple, and his face turned pale.

But he struggled to stand up.

"Captain, take me with you. I can still hold on. I'm familiar with this mine and I can always help you with something."

"Then, let's do it."

Seeing that he was determined to insist, Zheng Kaixuan did not stop him. It would be useful to take him along, very useful.

At this moment, Wang Xikui and the rest of the soldiers also rushed over.

Zheng Kaixuan asked someone to bring water and canned beef and fruit to Liu Daqiang, so that he could rest for a while and recover his energy.

Then, he repeated what had just happened to Wang Xikui and others, and spread out the map, so that Wang Xikui, Chen Shengli, Yang Wanli and other commanders and fighters could familiarize themselves with the situation in the mining area.

Immediately afterwards, Zheng Kaixuan quickly arranged the combat mission.

"The first battalion is responsible for destroying the puppet army mining police station, the second battalion is responsible for destroying the inspection team, the third battalion is responsible for dealing with the Japanese infantry battalion, and the fifth battalion is responsible for taking down the Japanese military police!"

"Four enemy positions were launched simultaneously. The third battalion then eliminated the thirteen Japanese artillery towers in the mining area."

"The first and fifth battalions will rescue the miners, and the second battalion will be responsible for destroying all facilities in the mine."

"Fire! Fight!"
