Tang Ning directed three people to fill, fire the shells and clean the barrel.

The magnetic element cannon exploded with light, and the shells shot out like meteors.

Two or three hundred miles away from the city walls, in a narrow land thousands of miles long from north to south, the space was torn apart by cannonballs, and a huge black hole swallowed everything. The torn space was tens of miles in front and back, and hundreds of miles long in north and south.

Countless demonic beasts were devoured. Under the fierce attack of the artillery shells, the attack of the demonic beast army finally slowed down. They attacked the troops surrounding the warships and chariots, and were gradually eliminated by the monks. Behind them were dozens of miles long and wide.

A huge black hole hundreds of miles across.

The torn space prevented the monster army from effectively supporting the front team. After suffering heavy casualties, the monster army's attack finally stopped temporarily.

As soon as the attack of the monster army stopped, the Mubei coalition forces on the left and right sides also gradually retreated backwards. The giant cannons on the city walls naturally stopped attacking, and both sides ushered in a brief period of tranquility.

Outside the city walls was a mountain of corpses and a sea of ​​blood. The corpses of monsters on the ground were piled up like a mountain, layer upon layer. The scarlet blood gathered into a small river and slowly flowed, and a fishy smell hit your nostrils.

Many warships and chariots were also damaged on the Xuanmen side. In the fifth column alone, at least hundreds of chariots and fleets crashed.

The two sides faced each other at a distance, and the Mubei coalition troops continued to gather, apparently adjusting their strength and preparing for the next wave of attacks.

The reason why Xuanmen was able to repulse the first wave of attacks by the Mubei Allied Forces was because when the Mubei Allied Forces attacked the formation earlier, the Fourth Army transferred a large number of elite monks into the formation, causing heavy damage to the Mubei Allied Forces within the formation.

.

Many high-ranking monks from Mubei were killed, and their combat effectiveness was greatly reduced. Coupled with the thousands of giant cannons displayed on the city walls, they were able to repel the Mubei coalition forces.

On the city wall, everyone breathed a sigh of relief when they saw the Mubei army retreating.

Tang Ning held a dark green tube that was more than ten feet long in his hand. He put it flushly into the cannon's filling port and pushed the upper hole of the tube to the top. He only heard a buzzing sound inside the barrel, and a long dark green tube was heard.

The tube burst with light and shook violently.

From the muzzle, countless black iron filings flew out. The whole process lasted for more than a hundred breaths. Countless black iron filings flew out from the inside, some even reaching the size of a fist.

These are the remains of cannonballs remaining in the barrel. If not cleaned in time, once the muzzle is blocked, the cannonballs cannot be fired and will directly explode the cannon and injure people around it.

According to the rules, the muzzle of the Shimei cannon must be cleaned every time it is fired.

As the slot handle was reset, the light of the long green tube gradually extinguished. Only then did Tangning take it out of the cannon, put it in the stone box beside him, and asked, "How many more cannonballs are there?"

Yang Yunzhi replied: "There are still twenty-seven rounds."

Tang Ning nodded without saying anything. Each cannon on the city wall fired 40 rounds of shells.

Obviously, the senior leadership of the legion also believed that it was impossible to defend the city wall with these giant cannons alone. Therefore, they did not fire multiple artillery shells. They only hoped to use up the number of artillery shells and cause as much damage to the Mubei coalition forces as possible before evacuating. Otherwise, at least one would be issued.
