The changes within the Ming Dynasty court forced Zhao Ming to end the southern expedition early.

During the process of colonial expansion, internal conflicts will indeed limit and destroy the process of overseas colonization.

In order to return to the Ming Dynasty as soon as possible, Zhao Ming decided to take Manila as soon as possible and negotiate peace with the Dutch.

At this time, after receiving the order to capture Manila within half a month, Tang Tong began to prepare for the siege the next day.

In the early morning, the Spanish soldiers on Manila discovered that the soldiers of Donghai Town under the city were different from the past. They were crowded with people in the trenches, and immediately informed the Governor Manlik.

At this time, Manlik stood at the top of the city wall and saw the soldiers of Donghai Town shouting horns along the trench, pushing several giant cannons, and advancing under the city. He couldn't help but feel frightened, "It's a mortar cannon!"

The Spanish officer on the city saw the mortars slowly approaching the city, and was intimidated and hurriedly said to Manlik: "Governor, the Chinese need to attack the castle with mortars!"

Manlik punched the fort wall, "Damn, cunning Chinese!"

There are many artillery guns in the fortress and no dead ends are left to shoot. The artillery can cover it. With a three-mile range around the castle, Donghai Town will attack any city wall from the ground and will be bombarded by artillery from at least three walls. When it rushes to the edge of the fortress, it will also have to withstand the musket shooting on each city wall.

Donghai Town digged a trench and advanced. The soldiers marched under the ground, and all the people were in the tunnel, so it was difficult for the artillery on the city to hit the soldiers of Donghai Town.

In this way, the original advantages of the trench were offset by Donghai Town's use of crisscrossing trenches.

The soldiers of Donghai Town transported ten mortar cannons along the trench to two hundred steps under the city wall, and placed the cannons into a previously dug deep pit.

These mortars are short and thick, and the body is pitch black, and each one is thicker than a strong man's waist.

The mortar cannon is different from the red-clothed cannon. The red-clothed cannon must be set up on the ground and aim straight to shoot. The mortar cannon, like the mortar, does not require direct aiming, but rather a lob. It can hide behind hills and stones without exposing itself and shoot at the enemy.

Now Donghai Town has placed these cannons in a deep pit. The Spaniards on Manila City cannot see the mortar cannons, and the artillery on the city cannot bombard the mortar cannon array of Donghai Town.

In the rear, Tang Tong stood on a horse three miles away from the castle. A general clasped his fists and reported, "Report to command, the mortar cannon has entered the artillery formation!"

Tang Tong put down the Qianli Miles Miles in his hand and said in a deep voice: "I made a military order in front of the Prime Minister. Within half a month, the city must be broken. The artillery team must be sent to bombard me immediately. The Prime Minister gave me fifteen days. I will wait within ten days before I can enter the city. Otherwise, I will remove my military uniforms and others before I apologize!"

"Here!" Many generals and schoolmen behind Tang Tong immediately clasped their fists together, and a solemn and murderous aura filled with them.

The Central Army's order flag was waving, and the drums sounded, and the artillery soldiers worked together to load dozens of kilograms of shells into the mortar.

In the deep pit, a long ladder was placed on the ground. The artillery team's command climbed up the ladder, exposed his head from the ground, stretched out his fingers, and yelled loudly while measuring at the fortress: "Adjust the gun position and raise the muzzle one inch!"

At this time, on the fortress, the Spaniard's artillery had already opened fire first, but the artillery hit the ground and could not hit the Donghai Town artillery team in the deep pit.

Manlik stood at the top of the city and saw that the shelling was ineffective. He estimated that the mortars of Donghai Town were about to start bombarding, so he was about to go down to the city to hide. However, at this moment, a loud noise suddenly came from outside the city, and a ball of white smoke immediately rose under the ground in the distance.

Manlik felt that the earth was shaking, and he saw an iron bomb flying out of the ground and soaring into the air.

The ballistics of the mortar cannon are different from that of the Red Cannon. The shells are thrown like stone throwers. The speed of the shells flying is much slower than the direct shooting of the Red Cannon, and can be seen with the naked eye.

The Spaniards on the top of the city initially saw only a black dot, and then the black dot quickly magnified, and had already drawn an arc in the sky and smashed towards the fortress.

The Spanish soldiers exclaimed in surprise, and several soldiers hurriedly protected the Governor Manlik. At this moment, the shells fell on the city wall and exploded instantly.

The loud "Boom!" sounded deafening, smoke and dust rolled, and a violent explosion blew up a strong wind, blowing the soldiers around him away. Many Spaniards were blown down by the air waves and smashed to the ground, smashing them to pieces.

Manlik was stunned. He followed the Spanish Navy who fled back from the sea that said that the Chinese had a terrifying shell. At first he thought that the navy deliberately exaggerated the power of the Chinese shells to cover up their failure. The warships were built of wood and could not stop such shells. The bastion was built for stone. It was extremely strong and could withstand the shells.

Now, his face turned pale when shocked. He didn't expect that the explosion was so powerful and it actually fell from the top of his head.

Fortunately, this was not around him, otherwise he would have been killed by the bomb.

On the city wall, the Spanish navy soldiers who gave up the battleship and entered the fortress to defend, looked at the explosion and were even more frightened.

The body of the mortar cannon is thick and short. With the same weight, the shells that can be fired are much heavier than the naval cannon. Therefore, the flowering shells fired by the mortar cannon are larger than the naval cannon and are several times more powerful.

Just as the city was bombed in a mess, the Spanish were shocked, and another series of loud noises came.

The Spanish soldiers on the city saw a few more shells rising from the ground, cutting through the sky, getting closer and closer, getting bigger and bigger, and roaring in fear: "Oh God! It's coming again!"

"Governor!" The Spanish officer roared and threw Manlik down. The shells roared over, and immediately loud noises were heard.

The walls of the castle were constantly hit by shells, and thick black smoke rose. Spanish soldiers fell into a large area with the explosion as the center, and screams and wailing sounds on the city.

For a moment, the bastion was in a mess, with thick smoke rolling everywhere, black smoke rising into the sky, and the injured soldiers wailed and rolled on the ground.

"Governor General, please leave immediately!" The Spanish officer helped Manlik up who was lying on the ground, and then quickly fled from the city. However, before everyone took a few steps, a shell landed beside the group. Several Spanish soldiers who were guarding were blown away instantly. The Governor General Manlik was also so excited that he sat on the ground with his head buzzing, and his expression was a little dull.

After awakening, Manlic suddenly roared anxiously, "Fire a gun and fight back!"

The artillery in Donghai Town is powerful, and the artillery in the city is firing like crazy, but they all hit the ground, so they can't hit the artillery in Donghai Town nestled under the ground.

The Spaniards in the city fired for a while, and the explosion kept ringing at the top of the city, blowing the Spanish gunners away, making the Spaniards finally recognize the reality and could only let Donghai Town bombard them. The Spaniards in the city were all in a mess and hiding in the dead corner behind the city wall, leaving only a few soldiers lying on the top of the city.

Outside the city wall, the mortar cannons in Donghai Town continued to bombard, and the cannons sounded like thunder. Under the bombardment of the mortar cannon, the smoke filled Manila City, and thick smoke rolled in the city, and howled everywhere, as if hell.

Tang Tong stood outside the range of the Spaniard artillery on the city wall and was watching the results of the shelling with interest, but did not immediately launch a strong attack.
