"The people of Songjiang are going to use the demon law again?"

After Luya, the commander of the Sulu Legion, who hurried to meet him, reported his discovery, both Suleiman VI and other civil and military officials were startled, and their first reaction was like this. Obviously, everyone thought that the previous explosion in the royal city of Manila was the power of ghosts and gods, not man.

At present, since the Songjiang people have re-dug the tunnel, it is most likely to repeat the old tricks.

"How's that okay?"

The political officer who fled with him muttered to himself, his face was as pale as if he had applied several layers of foundation, and anyone could see the panic in his heart.

In fact, not only him, but also some other officials' cousins were not much better. Similar rumors have been circulating for a long time, but now they are about to be confirmed. Once the walls of Morotai City were also blown down, how could these defenders in the city stop those wolf-like Songjiang people?

"There is a way for subordinates, but I don't know if it's easy to use or not."

Before coming to the report, Luya had already thought hard about how to deal with it. At this moment, seeing that everyone was at a loss, he took the initiative to propose his own proposal.

It's no different from dealing with an ordinary tunnel-digging siege, and you take the initiative to dig out from inside the city, and finally get through with the enemy. Then, a large amount of manpower was used to deliver water and pour it into the tunnel, flooding the entire tunnel. Although I don't know how the people of Songjiang used the tunnel to blow up the city, they must have cast a spell in the tunnel. As long as the enemy can't get down on your side, won't this problem be solved?

Digging out from the city, you only need to dig a short section, which is far less troublesome than Songjiang people.

The only thing that is a little difficult is how to accurately determine the direction and approximate depth of the tunnels dug by the Songjiang people, but it is not impossible at all.

In terms of depth, since the city wall is to be destroyed, it can be assumed that the shallower the distance from the surface, the better, provided that the soil layer above the tunnel can bear the load. As for the direction, it is mainly to use the echo strength of the water tank to position, after all, the location facing the tunnel, the echo of the water tank will be the loudest. With this method, you can roughly compress the range to a relatively narrow point, and the rest is up to luck.

Of course, in addition to this means, it was necessary for the Sulu legions to plan for the worst.

That is, if the means to stop the Songjiang people from blowing up the city wall are not successful, they need to build an urn city in the back, just like the Tongshan Guanzhong City Guards did. The only difference is that the siege troops outside Tongshan Pass are the city walls that were forcibly collapsed with a large number of counterweight stone throwers, while the Songjiang army outside the city of Morotai has mastered gunpowder weapons and can send the city walls and the defenders above into the sky in an instant!

"Just do it according to your method, you can call on all the manpower and material resources in Morotai City!"

Suleiman VI was not sure that either option would work, but he could not think of a better idea, so he could only push for Luya's construction as the only option. With the issuance of the imperial order, a large number of auxiliaries in the city were busy. Most of them were slaves of the lords of the manors in Sulu, and now they were used to dig tunnels and repair urn cities.

For a while, across the high city of Morotai, two forces inside and outside the city acted at the same time.

Every day, the Songjiang Army regularly launched offensives, which was both a kind of attrition and exhaustion. While fighting, deep in the ground under their feet, a group of soldiers also continued to dig forward day and night. Compared to the time in Manila, the soldiers were more skillful this time, and the tools they used had also been improved, and their speed had increased by at least two to three percent!

Under the uninterrupted rotation of the six groups, in just eight days, the Songjiang army dug the tunnel to a place 20 meters directly below the city wall.

At this distance, the echo of the inverted water tank on the inside of the city wall is already very obvious. The Sulu defenders in the city took the initiative to correct their direction according to this and tried to dock with the tunnel dug by the Matsue army. Behind them, a large number of soldiers, even the peasants who had been requisitioned, dug a pond nearby in advance to store water, and filled it with water in wooden barrels and tanks. As soon as the embankment is dug up, the water from the pond is immediately poured down the ditch into the tunnel.

In the patient waiting, the distance between the two sides is getting closer and closer.

From a high altitude, the excavation of the tunnel on both sides of the Biqu Pavilion www.biquge.info at least more than ten meters away. However, after adjustments and corrections, and the soldiers of the Sulu Legion began to dig horizontally in a direction parallel to the city wall, the relative distance between the two sides was much closer for a while.

Above the surface, this deviation is just a stone's throw away, and you can step over it in the blink of an eye, but unfortunately this is underground!

What the Sulu legionnaires did not expect was that their movements were in turn discovered by the soldiers digging tunnels in the Matsue army!

Although there were no special people on the Songjiang army's side to monitor the movements in the city, after the distance was so close, during a rotation, the new people took advantage of the silent environment to vaguely hear the movement. For a moment, they thought that the tunnel that had been dug was about to collapse, and they fled in fright. But after half a noise was silent, someone dared to come down again, and finally determined that the movement was not caused by their own tunnel, but by the people in the city.

The news was reported layer by layer, and He Shixiang was taken aback.

If the defenders want to get out of the city, they can open the city gates at any time, so why bother to play this hand. It is almost certain that the movement of the Sulu Legion is directed at them!

In other words, they have been prepared for the Songjiang Army's attempt to dig tunnels to bomb the city, and they are still trying to counteract!

"These Luzon people really can't be underestimated."

He Shixiang sighed, slightly changing his previous impression of the decaying Duchy of Luzon. This isolated island nation on the ocean is lagging behind only because of its isolation and decay, not because of stupidity. After only tasting the bitterness of Dynasty Manila once, he was even wary of this trick.

"My lord, what should we do now? Do you want to keep digging? ”

The attendant next to him asked.

If the defenders in the city are on guard, the people who dig tunnels on their side are likely to be at risk. Throughout the history of the previous dynasties in the Eastern Continent, the forces that used tunnels to attack the city have more than once been detected and used poisonous smoke and moat water to trap and kill soldiers.

"This ......"

He Shixiang hesitated, he had been digging for so long, it would be a pity to give up like this, and the key was to delay time.

After thinking for a moment, he decided to continue excavating, but with fewer people and more vigilance, he immediately evacuated if he noticed the slightest mistake. This will undoubtedly delay some time, but fortunately, it is not far from digging under the city of Morotai, and it is worth the gamble. Although a group of people may die in vain, compared to the deaths and injuries of other plans, He Shixiang is willing to take this risk.

The decision was made, and the soldiers of the Songjiang Army quickly made adjustments, and at the same time changed the direction of the excavation slightly.

I don't know if these small means have been effective, or if it is unrealistic to rely on such simple means to stop the Songjiang army, or if the Morotai defenders are unlucky, in short, the tunnels they dug failed to intercept the Songjiang army. Although the distance between the two sides would not even exceed a day, it was less than a day that made the city of Morotai repeat the mistake of the royal city of Manila.

After repeated comparisons and confirmations, the Matsue army determined that they had dug the tunnel under the city wall.

Immediately, the soldiers who participated in the last bombing of the city sent the encapsulated gunpowder underground. When detonated in a narrow area, the power of the explosives will be maximized, and the massive impact will blow down the walls of Morotai City, creating a siege channel. In the case that there is no way to carry a large number of counterweight stone throwers, this method is the best choice for the Songjiang Army, and all the soldiers are full of confidence in it!

"Report to the corps commander, the movement of the Songjiang people has stopped."

While the Matsue army was busy planting gunpowder and preparing to detonate it, the soldiers in charge of listening to the inverted water tank in the city issued an uneasy warning.

After receiving the news, Lu Ya's heart was shocked, and he had a strong premonition.

The last time in the royal city, there seemed to have been a brief silence before the tunnel collapsed. Now it seems that this silence is more like the calm before the storm.

"Let everyone get out, I'm afraid this wall won't be able to be saved!"

He said tremblingly, giving this order that was very frustrating to himself and the soldiers around him. Although he was very unwilling, Luya knew that if things really turned out as he had speculated, it would be useless to continue to leave people nearby.

An hour passed.

The people at the head of the city came to report, and they noticed that the Songjiang army had an abnormal build-up and transfer!

As routine sieges continued, such build-ups and manoeuvres would have not been easily noticed. Even if someone finds out occasionally, at best they will only think that a bigger attack is imminent, and will not think about anything else. But with Luya's orders, this sudden increase in size was keenly detected by the defenders.

"Can't be wrong, it must be so!"

The news from both sides provided the same corroboration, so that Luya no longer had any doubts. Almost a few minutes after he ordered his soldiers to prepare for battle on the newly built urn city, the Matsue army lit the gunpowder fuse on his side.

The final wait began.

With the experience of the last Wangcheng, this time the soldiers of the Songjiang Army calmed down a lot, but they became more and more curious about the earth-shattering power. Everyone wanted to re-examine whether that black powder really had the power to crack the rocks, or if it was just a flash in the pan under Manila.

And the results did not disappoint them.

After a few minutes of waiting, the lead burned to the end. Just like the last remake, the earth shook and a violent explosion burst into the sky. Countless earth, masonry and stone were lifted out for tens or hundreds of meters. The tunnels excavated by the Matsue Army and the Sulu Army soldiers invariably collapsed on a large scale.

The walls of Morotai City were even more crumbling in the violent explosion, and then collapsed!
