Soon, the engineers were under the command of the regimental commander, and then began to monitor the situation underground using the original listening tool listening urn. And this kind of listening urn is a very primitive thing, in the red alarm system, a few hundred silver dollars, it is simply a free price. And Wang Guorui, out of curiosity, also equipped some. However, it has not been used before, so it is also stacked in the warehouse of the engineering corps. But now it's actually used, and it's directly used to listen to the situation underground, so as to prevent the enemy from digging tunnels. The urn can also listen to where the enemy's tunnels have been dug and can then be prepared. The Spaniards didn't know that Taiwan had such a primitive prop as the listening urn, and they would not have thought of China's splendid war civilization at all, and this magical prop was invented as early as the Spring and Autumn Period and the Warring States Period.

Soon, an engineer beckoned to the regimental commander, and then the regimental commander immediately came.

"What's wrong?" The head of the regiment asked as quietly as he could.

After all, there are likely to be enemy soldiers digging underground, so you have to be careful to avoid the enemy hearing your words.

"I think I hear a voice, and I can probably point out where these guys are digging the tunnel!" The engineer said.

"Okay, mark it with a map!" The head of the regiment said.

Soon, the soldier marked the approximate route of the enemy's engineer on the map, and then proceeded to prepare for the enemy's excavation. Soon, other places began to discover the route of the Spanish excavation troops. And those Spaniards and engineers also began to excavate, they did not know that the Taiwanese army above had been listening to their tunneling route, and then kept an eye on them at any time. If they dig a little bit every time, they will immediately be extended by Taiwan on the map, so that their map will be monitored by Taiwan at any time.

"Alright, we'll be ready to meet them at their exit and give us a big gift! Since they have come to us, how can it be considered a way to welcome guests if we don't give them some gifts? The commander of the provisional engineer regiment grinned.

Outside the trench at the other end of the predicted Spanish route, the engineers began to pile up blocks. And there's a wire on the outside of this thing, and then you just turn the other end in a circle, and then you press this switch, and then the place explodes. And these are the explosives deployed by the engineering troops. If the enemy comes, it will inevitably be killed by explosives. The Spaniards in the tunnels didn't know about the situation, they were still in the process of excavating.

"Battalion commander, we have taken the preset route in Guò. About a meter in front of us should be the trench of the group of yellow-skinned monkeys. As long as we keep digging through here, then we can rush in and fight them. When the time comes, those yellow-skinned monkeys will be without artillery and all kinds of machine guns, and they will only be able to fight us at close range. And in close combat, we are several times outnumbered, and we have a much higher proportion of combat troops than them, so we will definitely be able to defeat them. ”

The Spaniards' plan is really very feasible, because of the 45,000 troops in Taiwan, in fact, less than 30,000 can fight in close quarters in the war, and the others are artillery, machine gunners, and some technical arms. The ability to fight in close quarters is poor and almost negligible. However, on the contrary, although the Spaniards' troops did not have so many weapons, they could fight in close quarters, and 150,000 of their 180,000 troops could fight in close quarters. In this way, once Taiwan's technological arms cannot exert their might, then the Spaniards will inevitably oppose the enemy and then occupy the initiative. Therefore, Taiwan is still very afraid of the Spanish civil warfare, and if the Spanish civil warfare is successful, then it will be very unfavorable for the Taiwanese army to really die. At that time, it was really very dangerous to face the result.

When the time comes, Taiwan will not only not be able to win, but will fall into a situation of being bullied by the enemy.

"Okay, don't dig one meter left!" Said the battalion commander in Spain.

"Why?" The Spanish soldier asked.

"Stupid. If it is dug out, then the Chinese yellow-skinned monkey will also be discovered. How could we, the engineers, who did not carry weapons at that time, be the opponents of a well-armed enemy? So, we have to be sudden, and then have a sudden effect. In this way, we were able to allow the troops behind to seize the enemy's first trench as quickly as possible, and then to capture their trench by means of civil excavation, as was just the case. At that time, our engineering troops will have made great achievements. Who dared to despise our engineering troops at that time? The battalion commander said.

"Put explosives!" said the commander of the Spanish engineering battalion.

"Commander, this place is about to explode, and they have already started to carry explosives?" The soldier who was listening immediately said.

"Okay, wait a minute, and when you feel the explosives halfway through, you'll give me ......," the engineer commander hinted.

"Uh-huh!"

The man with the electronic detonator snorted, indicating that he understood.

"Alright, put five pieces of explosives, and we'll be able to detonate them soon!" said the commander of the Spanish engineer battalion.

On the other hand, Taiwan's engineers have evacuated here and waited for the explosives to detonate.

"Plug your ears!" Said the commander of the engineer corps.

"Boom—"

With a loud bang, the explosives were detonated from inside the trench, and then a section of the trench was suddenly blown into a large circle depression. And the Spaniards' engineers, apparently, did not realize that they had just put the explosives, but the explosives on the other side were immediately detonated, and as a result, the explosives were immediately destroyed by the shock wave of the explosion, and none of them fled after that, and they were killed one after another. A huge crater was immediately opened in the same place, and then the pit was exposed. And the Spanish Army in the rear saw the explosion in front and did not know what was going on, they immediately rushed forward. However, they did not expect to be greeted by a pile of submachine gun bullets.

"Submachine gun, shoot me into this tunnel!" The Engineer Commander shouted.

"Dada......"

The submachine guns began to fire into the tunnel, and then the Spaniards who were just about to enter were immediately killed by the strafing of the Spanish soldiers who were about to enter. He was unprepared, and he was shot and killed.

However, what was even more tragic was that the Spanish soldiers in other tunnels heard the explosion, and instead of thinking that the enemy had cracked their plan, they thought that some comrades had blown up the tunnel, and then someone had already begun to attack. And they are all digging tunnels hard, and then they hope to reach the front as much as possible, and start attacking the Taiwanese army, so that they can get credit! How is it possible not for them to get credit and then get promoted?

"Boom Boom Boom Boom ......"

Soon, explosions began to explode in the surrounding tunnels, and these explosions were obviously not led by the Spanish troops, but by the Taiwanese army, and their engineers detonated the explosives, and those Spanish engineers were also killed by the explosives. And then, Taiwan's submachine guns will also take advantage of the explosion to strafe into the tunnel to prevent those Spaniards from rushing in. And even if there are no submachine guns, there are shotguns to attack, and the shotguns are simply a dozen large pieces, and one bullet is enough to block the entire tunnel.

The tunnels were obviously too narrow, and the shotguns were enough to cover the entire tunnels with a single shotgun, and then the Spanish soldiers were turned into a hornet's nest by the shotguns, and it was impossible to continue the attack. And this is the core of the tunnel battle, the important means is a sneak attack, if you can't sneak attack the enemy, you will inevitably face defeat. Once you are discovered by the enemy, the suddenness will be gone, and the enemy is ready, then you will not go to attack others, but rush to reincarnate, and then wait for others to surpass you!

"General Boris, our excavation plan has been a complete failure. The Taiwanese seem to have been prepared for a long time, they have already laid an ambush outside the tunnel, they first blew up our soldiers with explosives, and then strafed our tunnel, and then we suffered heavy losses! A soldier said.

"What? The Taiwanese found out? How did they find out? What's more, even if they find out, they won't be able to budget where we will dig and break through! Boris said angrily.

Boris had no idea the role of Taiwan's cheap weapons listening urn, under which the Spaniards' tunnels could be heard, so that they could not keep it secret. What they think is very secret, but under Taiwan's "backward" means, they are unable to hide from it.

"Forget it, we've failed this time, and then we'll think of another way to fight them again!" Boris said.

The commander of the provisional engineer regiment immediately said: "Brothers, since our enemy has given us this set, then we will also come without being rude. We all continue to give them one more time, so why don't we give them a good return? So, let's all listen to my orders, and we're ready to fight back! ”

"Good!" Everyone immediately shouted.

"Let's start work for me, and then clean them up for me!" Said the commander of the engineer corps. (To be continued.) )
