At the beginning, I became a county magistrate with greed of 500 million. The empress asked me to be

"The next phase of the road construction plan must be fully launched in five days. Order all troops to speed up their march and reach the Utengger Prairie within three days."

After listening to the reports from a group of officials, Xu Wan'er made a decision immediately.

"Five days, isn't that a bit too hasty?"

Jiang Wenzhong, standing aside, couldn't help but look worried.

"It doesn't matter if we rush. In this war, our army's plan to pave the road is of utmost importance."

"For the second half of the road, 20 engineering teams will work simultaneously, rotating around the clock."

Immediately afterwards, Xu Wan'er made an even bolder decision.

Previously, during the road paving process, they would only use ten engineering teams working simultaneously at most at one time.

Now, the number of engineering troops has doubled from ten to twenty, which will undoubtedly increase the difficulty of coordinating and commanding the entire project!

The officials sitting around the campfire were hesitant when they heard this, but Xu Wan'er not only held a much higher position than them, but also had much more experience in road construction than anyone else.

Therefore, after just a few breaths of time, everyone present nodded, expressing their support for Xu Wan'er's plan.

……

Under the city of Ulan.

With the 20,000 automated troops under Xia Yun's command, they officially launched a fierce attack on Ulan City.

The wilderness where Ulan City was located was suddenly filled with the deafening sound of dense gunfire.

The only difference is that it's different from previous battles.

This time, the source of the dense gunfire came not only from the automated troops under Xia Yun's command, but also from the Dune Dynasty troops defending the city!

"Marshal, the front-line attack has been blocked. The enemy is equipped with a large number of flintlock rifles, and has blocked all our soldiers outside the city wall!"

Qin Tianye, who had just returned to the central army tent from the front line, reported to Xia Yun with a dusty face.

In front of the map table, after listening to Qin Tianye's report, Xia Yun's face did not show any anxiety.

In this siege, from the very beginning, the Dune troops openly used flintlock rifles.

The battle has lasted for more than two hours so far.

Although the troops led by Xia Yun personally were equipped with automatic rifles.

But the troops did not carry heavy weapons after all, and there was a steady stream of enemy troops climbing up the city walls.

As a result, the enemy firepower on the city wall was equally intensive.

"Order all forward units to immediately organize defensive positions on the spot. Without my order, no unit is allowed to launch another charge."

After thinking for a moment, Xia Yun finally spoke.

The most crucial thing in this attack on Ulan City is speed.

If they stayed under the city wall for too long, enemy reinforcements would surely arrive.

By then, a fierce battle will inevitably break out between the two sides.

"In addition, this battle will be commanded by me personally. All officers and soldiers shall immediately come to the central army tent to discuss matters!"

In order to avoid any unexpected situations, Xia Yun decided to personally command the battle.

"I will obey your orders!"

At this moment, the anxious look on Qin Tianye's face had disappeared, replaced by an expression of utmost respect.

A short while passed.

All the generals who were originally commanding the battle at the front line returned to the central military tent one after another.

"Damn it! Those damn Dune soldiers are so brave that they are not afraid of our dense firepower at all. They are still climbing up the city wall!"

After Chong Heihu entered the central army tent, he immediately started cursing.

No wonder.

If the Dune troops defending the city had shown the slightest fear, they would have led their troops into the city.

But until now, those dune soldiers still look fearless.

Even though they suffered heavy casualties, the soldiers continued to climb the city walls and organized a dense firepower network.

"General, the eastern wall is too difficult to attack. Not only do we not have a firepower advantage, but the terrain conditions are also very bad. If it rains heavily later, I'm afraid all 3,000 soldiers under my command will be soaked in the rain."

Zhao Xinlei, who was responsible for attacking the east side of Wulan City, couldn't help but shake his head.

The terrain to the east of Wulan City is lower, and once summer clouds appear, rainwater will inevitably accumulate.

Upon hearing this, Xia Yun raised his head and glanced outside the central army tent.

At this moment, the endless sky was covered with dark clouds, and even the air was filled with a damp smell.

Needless to say, heavy rain is about to fall.

"General, I suggest canceling the feint attack missions in the other three directions, concentrating all troops, and launching intensive attacks in the four directions of Wulan City, all as the main attack points."

"After all, the enemy's numbers are not as many as ours. In this way, even if we pay a certain price in casualties, our army will definitely be able to capture Wulan City in the shortest possible time!"

Immediately afterwards, Xiang Wentian suddenly spoke up and made a suggestion.

In previous battles, the south of Ulan City had always been the main attack point, and these three directions were all used as feint attack troops.

This is also the tactic consistently used in all siege battles.

However, their current situation is different from the general situation.

The 20,000 automated troops under the city of Ulan now have not brought any large-scale siege weapons, let alone an ordinary catapult.

"enough."

Seeing that the atmosphere in the big tent was becoming increasingly chaotic, Xia Yun finally spoke.

"Our army has come a long way. Even if the enemy wants to ask for help, it will take at least two or three days."

"Pass on my order. From now on, Xiang Wentian and Li Taisui will immediately lead their respective troops to withdraw from the frontline battlefield, start digging soil in the plain area, and transport it to the South Gate front line."

"The rest of the troops remain on standby and maintain mobile combat at any time."

Xia Yun gave orders one after another.

Although their time was very tight, they were not too anxious.

As long as we can capture Ulan City within two days, we will have perfectly completed this strategic infiltration mission.

"Marshal, are you planning to attack Wulan City by filling the land?"

Qin Tianye was the first to react. With a look of surprise on his face, he asked.

"Yes, the soil in the fields outside Wulan City is loose, just right for filling the ditches outside Wulan City!"

Xia Yun nodded.

"As a general, you need to observe the weather and terrain, and respond to the situation with flexible strategies. Remember not to stick to the old ways and never change."

Xia Yun then continued to speak, his eyes sweeping over the generals present.

"I will remember the Marshal's teachings!"

Chong Heihu and others also came to their senses and responded in unison.

Soon, Xia Yun's order was passed down.

Xiang Wentian and Li Taisui's troops quickly withdrew from the frontline positions and rushed to the area south of Wulan City and began large-scale earth excavation operations.
