The tunnel operation of the Songjiang Army, after repeated verification and calculation, stopped when it reached the bottom of the city wall of Manila, which made the soldiers of the royal capital who were always listening to the movement of the water tank behind the city wall a little puzzled, after all, if it was a short effort, it could be said that the enemy was replacing the manpower digging the tunnel. But for the next few hours there was no movement, which had to surprise them.

What the Luzon people didn't know was that the Songjiang Army was carrying gunpowder and preparing the lead under the command of Zeng Siwu.

"Tap, you idiots!"

He lowered his voice, carefully reprimanded the ignorant soldiers, ordered them to put down with the lightest force possible, and then with a few assistants who had come with him, he piled up the processed encapsulated gunpowder and pulled the long lead.

The lead wire used by the Matsue military was roughly preliminarily processed with cotton thread and gunpowder. Although the treatment was done with as much care as possible, it was not possible to guarantee a uniform combustion rate, and it was difficult to accurately predict the time of explosion. In order to prevent accidents with too fast burning speed, Zeng Siwu specially used an extended double lead to ensure that there was enough time to evacuate the tunnel after the lead was ignited.

At the same time, the Matsue Army on the ground was also fully prepared.

As long as the city wall can be blown up, the light infantry and the improvised knife cart will be dispatched as soon as possible, and then the heavy infantry will follow and seize the gap. The combat effectiveness of the defenders of Manila, the royal capital, was not as good as that of the main elite of the Songjiang Army, and once the city wall that it relied on was blasted, it would inevitably fall into an unprecedented panic. If you grasp it well, you may even be able to defeat the defenders in the city and take Manila in a battle!

But the premise is that gunpowder is really as powerful as Zeng Siwu advertised.

"Prepare to clear the field!"

As the order was given, irrelevant personnel withdrew from the damp and narrow tunnels, and the officers of the Songjiang Army, who were quietly waiting for this moment, couldn't help but mutter.

Zeng Siwu's heart was actually more nervous than the officers waiting outside. He looked confident, though. But after all, this is the first actual combat of gunpowder weapons, and it is used to attack the royal capital of the enemy country, if it succeeds, it will surely be remembered in history. and, as the governor said, gradually change the pattern of warfare. But in case of failure, not to mention the ridicule of others. But saying that Chen Wu has been investing heavily for more than two years, Zeng Siwu felt that he had no face to see each other.

"It must be successful!"

He said a word, looked at one of his assistants, who was also nervous, and shuddered as he stretched out his torch and ignited the fuse.

At the moment when the sneer burned, Zeng Siwu didn't say a word, turned around as quickly as he could, and stumbled out of the tunnel. In fact, before coming, Chen Wu clearly asked him that he would never be allowed to take risks in person. Similar tasks can be entrusted to subordinates. As for the other words Chen Wu said, Zeng Siwu did and obeyed, but only at this historic moment, Zeng Siwu insisted on coming in person.

For the sake of his dead ghost master, explode!

The moment he rushed out of the tunnel, Zeng Siwu retreated, and at the same time turned his head and stared nervously at the city wall. According to his estimates, the gunpowder would explode in one to two minutes.

Thirty seconds passed.

A minute passed.

A minute and a half passed!

The officers of the Matsue Army who were waiting around him. Seeing that there was no movement for a long time, he couldn't help but steal doubts, inquiries and even joking glances from Zeng Siwu. Some officers muttered quietly. Yan Dao had long known that the flow of gunpowder was unreliable, and thought that he, like other Taoist priests in alchemy, was flattering and relied on deception to gain Chen Wu's trust.

However, Zeng Siwu is confident in what he has tried many times with his own hands.

He ignored the stares behind him and stared at the walls. Maybe the next second. The explosion will sound and the walls of Manila will collapse.

Exactly two minutes!

The time has exceeded Zeng Siwu's expectations, and there is still no movement on the side of the city wall of the royal capital. Feeling a little breathless, he began to wonder if there was a problem with the lead, and wanted to go down to check. But under the previous accident and the strict practical regulations formulated by Chen Wu. I didn't dare to go up rashly, so I could only continue to wait anxiously.

Every second at this moment seems as long as a day on a weekday.

The commotion and discussion behind it grew louder and louder, and there was even a clearly audible laughter. Although it was immediately stopped by He Shixiang with stern eyes, it could not change the fact that almost all the onlookers thought that the gunpowder bombing of the city had failed. Or, in the eyes of these officers, failure is normal. With these New Year's flowers, if you want to blow up the city wall that ordinary stone throwers can't collapse, what can it be if it's not whimsical?

It's been two and a half minutes since Zeng Siwu ran out of the tunnel!

Zeng Siwu's heart sank a little, realizing that the first detonation was likely to fail. But it doesn't matter, as long as the gunpowder is still there, you can try to detonate it a second time after enough time.

But the amazing change came suddenly at a time when no one expected it.

The gunpowder of the Matsue Army was strictly sealed and moisture-proof from the moment before it was loaded onto the ship. In comparison, the lead wire is poorly kept. However, the ground was relatively wet, and the lead burned slower than expected. Just when Zeng Siwu turned around for the first time and opened his mouth to say something to He Shixiang, the spark of the lead burned to the end.

The next moment, an earth-shattering explosion sounded.

Ten barrels of black powder are more powerful than anyone imagined. At that moment, the ground under my feet shook, as if an earthquake had been launched. The collapsed ground, the black clouds rising into the sky, and the muffled sound like thunder frightened all the soldiers.

Some superstitious officers, thinking that this was the coming of heaven, almost did not kneel directly to the ground.

The war horses in the camp in the distance couldn't help but neigh, desperately trying to break free from the reins.

The soldiers of Manila, the royal capital, were even more unbearable, especially those who happened to be near the city walls, and were nearly deaf by the unprecedented loud noise. There were even patrolling soldiers who accidentally fell directly from the city wall and fell to the ground screaming.

"What happened?"

The officers, who had been greatly frightened, rushed to ask questions after a brief recuperation. And just when I don't know who shouted, and then under the gaze of many people, countless rubble, dirt and earth exploded, and dense cracks appeared from the walls of Manila, and then collapsed with a slow, unstoppable momentum.

The gunpowder weapon, the first time it appeared on the Eastern Continent, it blew up the city wall of the Duchy of Luzon, leaving a strong mark in military history!

"This is the power of black powder!"

Witnessing this historic scene, Zeng Siwu's eyes became shining, and a fanatical look appeared on his face for the first time. (To be continued.) )
