At dawn, Yan Huai woke up early from his sleep, wearing armor as usual, ready to climb up to the city to observe the city defense. As soon as he stepped out of the gate of the government office, he heard a loud rumbling sound from afar, and then the same loud noise came one after another.

When he thought to himself that something was wrong, a soldier rushed to him and reported to him: "General, the enemy has begun to attack the city! They are using a catapult to shoot the city walls!"

Yan Huai hurriedly rushed towards the city wall without saying a word. As soon as he climbed to the top of the city, another loud noise was heard in his ear. The splash of dirt caused a blood mark on his face. He hurriedly leaned over the wall like other soldiers, and looked outward. Under this wall alone, there were more than 30 large trenchers of specific types. These trenchers were counterweight, and the stones emitted were extremely powerful, and even the stone bricks wrapped outside the adobe wall could be smashed.

In just a quarter of an hour, large pieces of stone bricks fell off on the trembling city wall. Liang Jun immediately launched a counterattack with a crossbow, which was originally placed behind some special tall pile walls dedicated to covering the crossbow. First, one stone bullet of the same weight as the hot bomb was shot out to correct the elevation and direction of the crossbow. After the stone bullet could hit the opponent's giant catapult continuously, the hot bomb would be used instead. At the same time, the Liang Jun's longbowers also began to snipe the enemy soldiers who controlled the catapult.

Several Sassanian soldiers were busy manipulating a giant counterweight trench. When they had just fired a large stone and were pulling down the throwing arm, they heard a dull sound, and a rock bullet flew over and hit the crossbar of the locking arm. With a loud noise, the crossbar broke and the rebounding stone hit the head of a Sassanian soldier, which immediately broke his skull and died. At the same time, a terrifying cry came from the air. It turned out that a Sassanian soldier who was placing stones on the catapult was hooked by the iron hook used to hang stone bags at the end of the throwing arm. He was thrown out and smashed on the Xihekou city wall, which turned into meat pie and slipped off the city wall.

Within a quarter of an hour, two more stone bombs hit different parts of the catapult. Obviously, Liang Jun had calculated and corrected the parameters of the crossbow. He began to throw fire bombs. When the fireball fell from the sky, the entire catapult was swallowed up in the flames.

Near another trencher with stones, a Sassanian soldier was about to pull the trigger, but a three or four-foot-long heavy arrow penetrated his chest. Another soldier stepped forward and pulled the machine hard to pull it out before the stone was thrown out.

Although Liang Jun fought back desperately with crossbows and longbowmen, it was impossible to completely stop the continuous bombardment of these giant trenchers, which greatly delayed their time to destroy the city walls.

Yan Huai thought to himself that if the bombardment continues like this, the city will collapse sooner or later. At this moment, the catapults stopped bombarding one after another. Yan Huai was puzzled and looked around at the clamp, and found that the Sassanian army was dismantling these giant catapults, obviously trying to transfer them.

It turned out that Sassanian general Azejart was also feeling sorry for his expensive heavy trenchers, for fear that if he continued to bombard them, these treasures would be destroyed by Liang's army.

Nejarth knew in his heart that Liang's crossbows attacked fixed targets very accurately, but the target of the bombardment movement could not be accurately measured because the projectile landing point could not be accurately measured unless it was shot directly. He was eager to think that the past few days, the deck of the ship was as stable as on the land. Why didn't I install these catapults on the deck of the warship and shoot the side of the city facing the water, and if the wall collapsed, it would also be easy to attack the city.

However, when these huge trenchers were dismantled, they were transported to the Sassanian Navy's wide-body sailing warships by using large trucks, and finally installed on the deck, the sunset had already fallen on the sea level. For the Sassanian Army, the day had passed like this, and Nejarth could only wait until dawn the next day to launch another attack.

The night is deep, there is no moon in the sky, but it is full of stars. Sassanian patrol ships passing by from time to time can be seen on the sea outside the water gate of Xihekou City. This kind of patrol ship is similar to the Liang army's sampan or small Viking warship. Each ship is equipped with seven to ten people and is equipped with dhows, which is extremely fast. Because the Sassanian warship is now equipped with heavy trenchers, it has strengthened its vigilance against the water gate of Liang army.

In addition to these patrol ships, Nejalt also assigned a warship to monitor the water gate. As long as the Liang army's warships opened the water gate and launched an attack outside, the Sassanian warships anchored on the nearby water surface would immediately receive a warning and use their advantage in their troops to rush forward to "group and beat up" the other warships.

There is an inconspicuous side door on one side of the water gate. The upper edge of the door is only less than two feet above the water surface. This is still when the tide is low, and the entire door hole is submerged under the water when the tide is high. The Sassanians only think this is a sewage outlet in the city, so they don't take it seriously.

But at this moment, one thing that looked like a bucket "floated" from the hole. In fact, this was the Liang army's semi-submersible ship. Xihekou Army Town has nine such semi-submersible ships.

Nine semi-submersible ships successively emerged from the "hole entrance" and rushed towards different targets quietly and slowly like giant crocodiles lurking in the water. Their watchtubs are likely to be discovered by the other party's patrol ships or the lookout soldiers on the large ship during the day, but in this dark night, no matter how good the eyesight is, it is difficult for people with good eyes to discover them.

On the deck of the warship that was specifically monitoring the water gate of Xihekou, a Sassanian general was whistling to the edge of the ship, preparing to pee at the sea. Halfway through peeing, a loud bang was heard, and the entire hull shook and then tilted twenty degrees. The general was caught in the air with a thunderous thunder. Soon afterwards, other soldiers on the ship also exclaimed.

It turned out that a Liang army semi-submersible ship surfaced on the side of the warship's back facing Xihekou City, only more than ten battles away from the side of the warship.

Then the Liang army sailors put a thick, macadamia-shaped desulfurized rubber rubber band on the deck in a few breaths, and shot a stone bullet from close range. The stone bullet instantly pierced the side of the Sassanian warship, creating a hole the size of a washbasin.

After more than ten breaths, the soldiers on the Sassanian warship had just reacted. When they knew there were enemies nearby, a fireball drilled into the cabin from the holes of the size of a basin. The closed cabin exploded in an instant, and the flames rushed through the holes in various gaps, and then the screams and howlings of the Sassanian soldiers were...
