After hundreds of years, why is this tactic extremely rare and there are almost no successful battle examples? Meng Jiucheng once couldn't figure it out.

Until now, Meng Jiucheng has not figured it out and doesn't want to worry anymore. Anyway, he just used it well. It is certain that the Song Dynasty is still the only one who leads the way. Moreover, Nanjing City can be successfully blasted by the Taiping Army, so what is this mere Rizhao City?

Every actual combat is a good opportunity to accumulate experience and improve technology. Although the engineers have been formed and trained, they still lack practical experience.

After waiting for a long time, the engineer team finally completed the survey and ran back to report the situation to Meng Jiucheng.

"Report to General, the soil is of the right quality and there is no water accumulation for more than five feet. You can start digging the tunnel." Wang Xie, the captain of the engineer, wiped his sweat, and the soil and mud, immediately became a flowery face, but he could not hide the excitement and excitement in his heart.

Wang Xie raised his cheekbones, there were some small wrinkles on his forehead, and his eyes were hidden under his thick and black and drooping eyebrows; his shoulders were round and his neck was hidden inside, and his head seemed to grow directly from his chest.

Wang Xie, who was a miner, looks a bit weird, but he is definitely strong, which can be seen from his exposed thick neck.

"How much time will it take?" Meng Jiucheng felt that since it was a practical drill and increased experience, there was no need to be busy.

Wang Xie thought for a moment and said, "I think it's feasible, it can be done at most in three or four days."

Meng Jiucheng nodded with a smile and said, "Then let go and let the auxiliary soldiers dig trenches and approach the city first, and reduce your workload, speed up the attack speed, and strive to break the city in five days."

Breaking the city in five days, and not a crazy attack, this is definitely an amazing speed. Not only Wang Zhongfeng, but Han Shouzhong found it unbelievable, but it was something that Zhao Tiancheng and others in the city never expected.

The night was shrouded in the dark blue sky, spreading the wings of light around Rizhao City.

Suddenly, the golden drums in the west of the city sounded, breaking the silence of the night and causing the defenders' nerves to suddenly tense.

Zhao Tiancheng hurriedly put his clothes neatly, carrying a sword in his hand, climbed the city to defend against the enemy. However, the expected battle did not happen. With the moonlight, he saw only the shadows outside the city swaying, and the sound of excavation was endless.

"This is—" Zhao Tiancheng observed for a long time and said to himself: "Digging a trench to block the city gate, trying to trap our army in the city? Or do you follow Zhuge's plan and make a sound of the golden drum to exhaust our army?"

Originally, the city-ring moats had been dug outside the city, but the Red Turban Army seemed to feel that it was not safe enough, so they dug trenches outside the city gate, as if they wanted to completely surround Rizhao City.

Zhao Tiancheng was not sure about the reason, and the enemy was outside the range, so he had to watch the changes at the top of the city and command the generals guarding the city in other directions to be vigilant and not to ignore it.

Thousands of soldiers took turns to construct the construction and soon dug an annular trench outside the city gate, which was more than meter wide and less than five feet deep. The digging soil continued to accumulate, slowly forming a shielding wall.

Then, the construction direction turned to Rizhao City, and several trenches with 45 degrees angles to the trenches around the city were zigzag and zigzag, digging forward in a zigzag shape, digging forward at a speed visible to the naked eye, and soon cross-connecting with the trenches dug by the defenders.

Filling the trenches? The Red Turban Army wanted to fill the trenches in this strange way, which could indeed reduce casualties. Zhao Tiancheng seemed to have some understanding and immediately ordered the city to shoot arrows and shoot to stop the enemy's actions.

Arrows shot out from the city walls, all shot, and were effectively covered by zigzag trenches, with almost no threat.

The two trenches continued to stubbornly extend forward. They broke through the trenches under the city wall, and were like sharp arrows, stabbing Rizhao City closer and closer.

The sound of golden drums suddenly sounded in the south of the city. Zhao Tiancheng, who had been protected by his personal soldiers, suddenly woke up. This was a sound of attacking the east and west, and the enemy's main attack was in the south of the city. He shouted loudly, and rushed to the south of the city with a whistle and quickly took the command.

On that day and night, Zhao Tiancheng had almost no eyes closed, and the Song army in the city was also disturbed repeatedly. The sound of the golden drums was east and south, and the shouts rushed to the north and west, making them not know where the opponent was going to attack.

It was dim and the Red Turban Army ended its operation. Zhao Tiancheng led several generals to inspect the city defense. When he saw that the enemy seemed to have made no progress, he felt that his confidence was still there.

"It is a delusion to think of the enemy's siege to break the city." Zhao Tiancheng looked contemptuous, pointed his hand outside the city, and said, "The enemy's arrogant and unproficient in military tactics, and he must not even understand the siege of the city. It should be noted that long-term will lead to dull troops and sharp weapons, and if the attack is done, the force will be reduced. If the city does not pull out, this is a disaster for the attack."

"What the lord said is very much." A man who looked like a master quickly echoed: "One will flourish, then decline, and then exhausted, and three will be exhausted. As long as our army is not intimidated by the enemy's weak power and persists, the enemy will be unable to defeat his anger and ants will attack the city, which will only cause heavy casualties."

"Sir, wise." Shao Kai also felt that the enemy was unable to attack the city and had not seen any large siege equipment. He pointed outside the city and said, "The enemy has only begun to build siege equipment now, which shows that his skills are exhausted."

That's right, the Red Turban Army outside the city was constantly transporting wood, and several things that looked like ladders were placed on the ground at will, and soldiers were also transported in the trench.

Going out of the city to drive away? This idea flashed through Zhao Tiancheng's mind, but it was rejected by him. Without the protection of the city wall, a war of attrition was unwilling to carry out by the defenders with disadvantaged troops.

"Stay on shifts and strengthen your vigilance. Never relax, so that the enemy can take advantage of it." Zhao Tiancheng gave a very normal and nonsense order.

"Sir, wise."

"The enemy will have no chance to take advantage of the arrangement."

Zhao Tiancheng was proud of himself, and waved his hand with a smile, continuing to patrol the city defense.

The sound of golden drums sounded again, and the Red Turban Army continued to fill the trenches, pull out piles, and attack the city, sometimes in the east, sometimes in the west, sometimes in the south, and sometimes in the north. Another group of soldiers kept calling in the trenches outside the city to persuade them to surrender, and psychologically disintegrating.

Golden drums, feint attacks, and shouting are not the main purpose, but to cover the sound of tunnel excavation. In the trenches in the west of the city, the engineers were nervously carrying out earthwork. Because it was only 200 meters away from the city wall, the excavation project volume could be reduced to a minimum. They had started construction in the middle of the night and installed support according to the progress of the project to increase load-bearing and avoid landslides. At the same time, with the columns as the boundary, the middle of the excavation section, leaving space on both sides to transport the soil slag and continuously filling the deep trenches.

As noon approached, Zhao Tianchengcai finished the city defense patrol, and the accompanying generals dispersed. Guerrilla Shao Kai rode back to his house under the escort of several personal soldiers.

As soon as he returned to the yard, his wife came to ask about her well-being with her belly, and then asked about the situation of the city with concern.
