As the midsummer season entered, Yunfeng, Shihu, and Liu Yao were all working hard, waiting for God to send a heavy rain.

Since Murong Huang was good at observing the sky, Shi Hu would often ask when there would be a drenching rain. Unfortunately, Murong Huang did not understand modern meteorological knowledge. The ancients focused on observing the sky when observing the clouds. However, due to the influence of the subtropical high pressure,

During the rain at this time

The center is located in the Jianghuai area, and the northwest region is controlled by the warm and high pressure of the mainland. It has high temperatures, little rain, and cloudless skies. Facing the blue sky, no matter how high Murong Huang's meteorological level is, it is useless, so he is always struggling.

Unable to give an exact time.,

However, Yunfeng knew that in order to have a drenching rain, the subtropical high had to be further strengthened to push the frontal rainband northward, and this time usually arrived in mid-June. He took the time to train his troops and conduct targeted simulation exercises, hoping to

When the bow and arrow are ineffective, rely on the terrain of Jianzhang Palace to engage in hand-to-hand combat with the enemy.

During this period of time, Chang'an defenders of varying numbers came out of the city almost every day. Although Liu Yao took strict precautions, the Chang'an city wall had a radius of thirty miles. He could guard against this end, but not the other end. At the beginning,

It was just a small-scale operation of a few people, but later it developed into a whole group of people fleeing. They went to the Qin army to eat and drink, and Yunfeng refused to accept anyone who came. Who wants to stay in Chang'an and suffer from hunger?

Unknowingly, it was mid-June. This day was June 12th. Just after the afternoon, suddenly, "Crack!", a burst of thunder rolled across the sky, and in the blink of an eye, the fierce sunshine was

The sky was replaced by darkness and the earth was dark. The strong northwest wind made the tents roar, and the sky and the earth were filled with flying sand and rocks!

Shi Hu immediately ran out of the camp and saw dark clouds rolling in from the northwest. He immediately struck his palms with excitement and shouted loudly: "God, you bastard, I have been waiting for you for more than a month!" and then asked again.

Xiang Muronghui: "Yuanzhen, can we send troops at this time?"

In the past month or so, there had been occasional light rains. Shihu couldn't bear it anymore and wanted to attack, but Murong Huang stopped him every time. The most intuitive look is that the clouds in the sky are not thick enough, dark enough, and cannot reach the enemy.

to the conditions in his mind.

At this time, Murong Huang raised his head and looked to the northwest. The dark clouds in the sky were changing unpredictably. Along with the rolling thunder, streaks of lightning danced in the sky like golden snakes, especially in the northwest sky. A large mushroom-shaped cloud was white above and gray below.

The clouds are swelling and rolling in. It looks like a prelude to heavy rain.

Murong Huang did not hesitate, nodded and said: "This opportunity cannot be missed, and it will never come back. General, please send troops immediately!"

"Okay, raise the tent!" After saying that, Shi Hu led his generals towards the Chinese army's tent.

At the same moment, Jianzhang Palace in the west of Chang'an City saw a sudden change in the sky. Yu Wenjun opened his arms with joy on his face and let the strong wind tear his clothes wantonly. He squinted and said: "It's so cool! Shihu

It's coming soon, General, why don't you make preparations earlier?"

Yunfeng thought so too, and immediately turned around and called out: "Send the order, all armies enter the designated positions according to the predetermined plan!"

"Yes!" Several personal guards ran in all directions.

After a while, the drums of Jianzhang Palace were beating, the horns were blasting, and groups of sergeants carrying various equipment filed out of the camp and arrived at the designated location to set up defenses.

Surrounding the entire Jianzhang Palace, a long trench with a width of two feet and a depth of one foot has been excavated. There are many arrow towers behind the trench. There are several trebuchets around each arrow tower, and the front of the trebuchet is packed with sand.

Protect it, rely on mud and sand bags, and station a mixed team of crossbowmen each.

Since the string of the crossbow is made of hemp rope, it will become useless after a few hits in a heavy rain. At this time, bows and arrows have to be relied on to stop the Jie army. The bowstring is made of cowhide and tendon, which has a certain degree of protection.

It has rain function and is not afraid of rain in a short period of time, but if it is used in the rain for a long time, it will still be scrapped.

In fact, the biggest damage caused by rain to a bow is the bow body. The bow body is made of animal glue, which will melt when exposed to water. Although the outside is sealed with bark or animal skin, water will inevitably get in. As long as the water vapor

If you go in a little further, the material of the bow body will loosen. This loosening is irreversible. However, Yunfeng will not give up a few bows, and there are also special throwing spears in the mud bag position. This is the key to the crossbow.

If all are scrapped, they will be used as emergency backup.

Further inside, a multi-level defense system was built based on the complex terrain of Jianzhang Palace. On each high ground, there were archers and crossbowmen ambushing them. Behind and on both sides of the high ground, there were teams of warriors engaged in hand-to-hand combat.

Yunfeng trained them based on Qi Jiguang's mandarin duck formation. They formed a group of twelve, with the captain at the front, the second two holding a long shield, the other holding a rattan shield, and the next two holding wolf whisks. The wolf chops are made from moso bamboo growing in the south.

The old and strong ones cut the end of the bamboo into a pointed shape and left sharp branches around it. Each wolf chop is eight feet long. These wolf chops are

They were all specially brought from Hanzhong. Then came four spearmen, two on each side to support the shield bearer and the wolf sword bearer respectively, followed by two saber bearers, and the last one was the cook. The division of labor for various weapons was clear.

, the key point of the whole array is to cooperate as a whole and enforce orders and prohibitions, which can be effectively used in small-scale operations in complex terrain.

As for the iron spears and giant shields, Yunfeng did not arrange them. The terrain of Jianzhang Palace was complex and full of obstacles, so the cavalry was useless. If the Jie army wanted to attack, they could only launch a group charge with infantry after breaking the outer trench. But the bed

The crossbow was also hidden by Yunfeng Snow. The bed crossbow was basically useless on rainy days.

About a quarter of an hour later, the defense system of Jianzhang Palace was well arranged. Yunfeng led everyone to a high place and looked northeast. Surprisingly, there was thunder and lightning in the sky, and strong winds roared all around, but not a drop of rain fell.

Zhang Lingyun felt a little uneasy and turned around and asked: "Yunlang, what's going on with the weather? Is Shi Hu not coming?"

Yunfeng was unsure. Based on his experience in his previous life, it was always windy but not raining, which meant that the place was on the edge of the rain zone. It might rain or not, so he said uncertainly: "Just have a look.

If Shi Hu doesn't come, let's just treat it as a drill. In fact, Shi Hu should be more anxious than us. This time he attacks Guanzhong. In addition to getting

We have reached nearly a thousand miles of uninhabited land, and there is nothing else. However, we have gained two million people in Guanzhong. By this time next year, these people will be productive, and the strength of our Qin State will only become stronger and the stalemate will last for a long time.

, how can Shi Le beat me? Shi Hu will not be unclear, he should come as soon as he has the opportunity."

Zhang Lingyun nodded: "I hope Shi Hu is a sensible person." As he spoke, he continued to cast his slightly anxious eyes forward.

"Look, Shi Hu is coming!" Yu Wenjun suddenly pointed.

On the ground in the northeast, a giant military formation gradually appeared in front of everyone's eyes. When they got closer and took a closer look, they saw that there were 50,000 cavalry guarding the left side of the military formation, that is, the flank near Chang'an City, and 30,000 cavalry on the right side.
