Before the army set off, hundreds of truckloads of supplies were specially pulled from Qingshan County, most of which were cement, and a few trucks were gunpowder.

The former was a sharp weapon used by the Chen Dynasty to resist the attack of bandits, and in an unimportant small city like Yongguan, the city wall was rammed with yellow mud, piled up layer by layer, also called rammed earth wall.

In the eyes of ordinary people, the city wall that does this is already relatively good, but in the eyes of Chen Chao, there are only two words, garbage.

Yongguan has not experienced a decent war for many years, years of wind and rain erosion, coupled with disrepair, the rammed earth wall is as fragile as paper, arrows and soldiers' spears can easily penetrate the rammed earth wall, and then the bandits will not use the siege weapon such as a ladder to attack the city, with the help of the spear piercing the rammed earth wall, with both hands and feet, you can easily climb the city wall.

This is also an important reason why the Chen Dynasty wanted to build the city wall as soon as it came to Yongguan.

The Chen Dynasty believed that cement acted as a binder, and that the stone walls made of stones would make the bandits plant a big heel.

Whether Yongguan can be defended depends on whether the stone wall is hard or not.

As for those carts of gunpowder, Chen Chao didn't plan to use them so early!

The number of these things is scarce, and if you use a little, you will have to use it at the most critical moment.

In just a few days, Shi Shu gradually changed from the initial doubts to shock and surprise, under the arrangement of Xu and Li, 1,000 soldiers were engaged in the reconstruction of the city wall, and the new city wall was reinforced on the basis of the original city wall, along the front and back sides of the old city wall, each built a stone wall nearly 30 centimeters thick.

The bottom of the two stone walls is two zhang apart, and the higher you go, the narrower it becomes, and when the stone walls reach a certain height, they backfill the two walls with muck and stones. Due to the existence of the old city wall, the amount of backfill work was greatly reduced, and in just a few days, the new city wall was already half a person high.

Only 1,000 people were needed to build the walls every day, day and night.

It is rotated every two days to ensure the speed of construction of the city wall.

As for the soldiers who did not participate in the construction of the city wall that day, they still trained as usual.

Training troops for a thousand days, using soldiers for a while.

No matter what time it is, you can't afford to leave your training behind.

However, there have been many changes in the content of the training, and it is no longer mainly about physical fitness, but about practicing battlefield fighting skills.

Although there are only 5,000 people in the Changsheng army, there are sword and shield soldiers, spearmen, and archers...... The whole nine yards.

Soon after, the soldiers will have a fight with the bandits, and the knives must be held steady and the arrows must be shot accurately.

Several lieutenants profoundly implemented the plan formulated by the Chen Dynasty, and everything was carried out in an orderly manner, and the situation developed on the good side.

Everyone else was doing things, and Chen Chao, who was the commander of Yongguan, naturally had no spare time, in the dense forest outside Yongguan City, Chen Chao was directing soldiers to cut down trees.

After the trees were cut back, all of them were transported back to the city, half of them were made into sassal wood and placed at the head of the city for later use, and the other half of the wood with higher hardness and better toughness was used for other purposes in the Chen Dynasty.

Anyway, it just can't leave anything useful to the bandits.

was chopping down the tree, Ning Baizhi jumped over, saw a lot of soldiers at the scene, first hugged Chen Chao's fist, and then said:

"General, my scout battalion has gained something again today."

"Oh?"

Chen Chao's eyes lit up and he became interested.

Since Ning Baizhi's eldest brother Ning Baiying was promoted, Ning Baiying was promoted from a big soldier to a captain in the scout battalion, which has caused many people to be dissatisfied, and the soldiers think that the rewards and punishments of the Chen Dynasty are not clear.

They thought that Ning Baiying had only killed a dozen mountain bandits, and he was not qualified to jump a few levels in a row and directly serve as the captain of the scout battalion.

But in recent days, these voices have faded away.

Because the scout battalion, under the leadership of Ning Baiying, was already the most dazzling existence in the Changsheng army.

Before the official war with the bandits, more than 50 heads had been saved under the scout camp tent, all of which were the heads of the mountain bandits who came to inquire about the news of Yongguan.

It's easy for the mountain bandits to come over, but it's hard to go back and report the news.

"Tell me, what did you gain today?"

Chen Chao looked at Ning Baizhi, his eyes were doting.

Since that night, the exchange has been profound.

The relationship between the two can be regarded as formalizing the relationship between men and women.

Ning Baizhi's technique is also advancing day by day, and her teeth will at least not be chattering Chen Chao.

Ning Baizhi tilted her little head, crossed her hands on her waist, and said happily:

"Today, I killed the eleventh bandits, and there is a small leader of the mountain bandits, and I will kill three of them alone."

"Really? It's really amazing, and the merits will be recorded for you. Chen Chao didn't hold back, reached out and rubbed Ning Baizhi's head, and said with a smile.

Ning Baizhi enjoyed this kind of stroking very much, squinting her eyes, rubbing hard, and her tail was eager to go to the sky.

She looked a little embarrassed when the other soldiers who were cutting trees came over, but there were a few who still looked good, and most of them were working hard to cut wood and prepare for the big war.

The two chatted briefly about something else, and Chen Chao said, "By the way, I'll give you an important task." ”

"General, please say, promise to complete the task." Ning Baizhi is full of confidence.

After killing a few mountain bandits, she already felt invincible in the world.

Chen Chao beckoned, called Hou Ji, and brought a map.

This map shows the terrain near Yongguan.

Chen Chao stretched out his hand and pointed to the upper reaches of the Yonghe River, "You take a few people here to investigate, it's best to map the terrain of this place in detail and bring it back." ”

Ning Baizhi blinked and nodded.

Before Ning Baizhi left, Chen Chao was not at ease, and said a few more words, "Let your brother go with you." ”

"It's best to set off at night, to avoid the bandit checkpoints along the road, and if you are faster, you can rush back in the early morning."

"If there is too much obstacle on the road, don't go, turn around and come back in time."

Ning Baizhi had already run away and beckoned to Chen Chao, "Got it......"

Watching Xiao Nizi jump and jump, Chen Chao stood in place and smiled.

The place where Chen Chao wanted Ning Baizhi to go was the bend that led to the diversion of the Yonghe River.

I heard that the rocks there collapsed, blocking the original river channel and forming a dammed lake, so the Yonghe River had to be diverted.

Chen Chao wanted to know the specific situation there.

If conditions permit, perhaps a drama of flooding the Seventh Army can be staged.

At that time, it will not cost a single soldier to win a complete victory.

Just thinking about it, from the direction of Yongguan, the city gate came out and rode at a very fast speed.

The man came galloping on horseback, grabbed the reins on the periphery of the dense forest, jumped off the horse, ran a few steps, and came to Chen Chao, his eyes could not hide the excitement.

Chen Chao patted the sawdust on his body, turned around, and spoke first: "What's the matter, so happy?" ”

Someone hugged his fist:

"General, the escort officer who escorted food and armaments is here, and he is already at the east gate at this moment!"
