A day passed, and Guo Shao didn't sleep well at night.

Early the next morning, the light outside the tent was hazy and foggy, and the weather should not change, and the fog was formed last night.

"Your Majesty, I will boil hot water for you." Lu Chengyong said behind him.

"No need." Guo Shao withdrew his gaze from outside the tent door, buried his head, and poured cold cold water on his face with both hands. Exhaling with a "whew", he continued to wash his face with cold water.

His mind seemed to clear up a little, and he clearly saw the green tendons and pores on his arms, and the water droplets on his copper-colored skin. When he straightened up, a personal soldier next to him handed over a cotton towel, and Guo Shao wiped his face and arms casually.

"Rustle......" An attendant was grinding ink. Neat footsteps sounded outside the tent, and two columns of soldiers in armor walked outside, and the two junior generals handed over the talisman step by step.

Guo Shao dropped the towel, walked to the wooden table and sat down, lifted the brush and dipped it back and forth in the inkstone, then quickly drew a crooked right-angled triangle on the paper, and then drew a vertical in the middle.

This vertical line is like the height of the city wall of Youzhou City. One right-angled side is the watchtower, and the other is the ground distance from the watchtower to the catapult position in the city.

The vertical line (city wall) divides the large right triangle into two similar triangles, one large and one small. Similar sides are proportional, junior high school geometry knowledge, it is very simple to estimate; At least for Guo Shao.

If you want to build some watchtowers where you can see the catapult position...... First of all, the nearest position from the wall is 200 paces (about 300 meters), and if it is too close, it may become a fixed target within the range of heavy fortification weapons such as catapults and ballistas. Secondly, the city wall is three zhang high (about ten meters), and according to the proportion of the triangular side length, if the watchtower is six zhang high, you can only see the scenery in the city 200 steps away from the city wall.

That is, it proved that it was completely impossible to see the ordnance positions in the city from the watchtower...... It was impossible for the Liao army to place the catapult 200 paces away from the city wall, so that it could only fight its own people.

At this moment, a "woo...... sounded in the air The sound of the horn ...... "is of different lengths, and the tone is very boring and monotonous.

Guo Shao raised his head and put down the brush and looked up to observe the light outside. It's dawning, but it seems like it will take some time for the sun to rise.

An attendant wearing a cloth shirt and combing his hair in a bun entered and said, "Your Majesty, breakfast is ready." ”

"I'll rinse my mouth first, and then I'll eat." Guo Shao's tone was steady.

The sound of the horn outside the account will distract people's attention and make Guo Shao feel a little irritable; And it's a signal of readiness and accelerates the sense of urgency. But he still didn't panic, and like some ministers of the court in Tokyo, he rode a horse and ate breakfast.

It's just that his movements have become noticeably faster, fast and not chaotic.

In Guo Shao's heart, he has always believed that everything is composed of atoms, molecules and other particles, and this concept will imply to him: keep the habit of small things, and still control big things.

He packed up, picked up a short sword with a gold-trimmed scabbard and hung it around his waist, and lifted it into a convenient position. Several attendants in the account bent down together to salute Guo Shao.

The sun has risen in the east, and it is still sunny today. But the residual smoke over the camp made the sun look dim, as if a haze was hanging around it.

Just like Guo Shao's mood, things are really not going well.

Walking out of the tent, the line of sight is wide, there are knights running outside the camp, a large number of soldiers in the camp are preparing weapons and ordnance, some craftsmen are building equipment in the camp, and the saws make a "whoosh" noise.

As soon as he walked outside the big tent of the Chinese army, he suddenly saw Jing Niang walking quickly, Guo Shao slowed down and waited.

Jing Niang looked back left and right, and handed a torn envelope to Guo Shao without saying a word.

The secret outpost of the Bing Cao Division had already found a large number of Liao cavalry between Danzhou (Miyun) and Shunzhou. Guo Shao pondered slightly, and said in his heart: As expected, the Liao army is still the nearest Gubeikou after all.

Walking into the big tent of the Chinese army, a cadre of civil servants and military generals were already waiting there, and when they saw Guo Shao, they all got up and saluted.

Guo Shao strode to the top position and sat down. Wang Pu immediately clenched his fists and said: "Lao Chen has one thing to report first, several tunnels were seeping water last night, so he can only abandon it and choose another place." ”

Guo Shao frowned and said, "Why is the water seeping now?" ”

As soon as the Zhou army arrived in Youzhou City, as soon as they began to repair the siege fortifications, they chose the location to start digging tunnels...... ** bombing the city, infantry artillery coordinated siege of the city, tried and tested repeatedly, they were still very skillful this time, and there was no reason to change these tactics.

Wang Pu said: "The groundwater in Youzhou seems to be of different depths, although we have dug wells to test the depth, but with the progress, there is still water seepage. ”

Guo Shao listened and said: "Choose a new location, and I'll go to the site to inspect it later." ”

Wang Pu asked again: "Last night, the Chinese army discussed the construction of a watchtower, can the military government of the former battalion arrange manpower?" ”

Guo Shao felt that repairing the watchtower was of little use...... But it is not completely useless, at high places, it is easier to estimate the position of the enemy's catapult by the stones projected. Moreover, the Chinese army immediately came up with a countermeasure, which can also stabilize the morale of the military.

As for the method of filling the river and attacking the city, even if there are more casualties than before, it cannot be stopped!

Time is pressing, and the first reinforcements of the Liao army have entered the Hebei region. Guo Shao immediately took out the report of the soldier Cao Si and handed it to Wang Pu, and ordered to know all the departments with the situation of the Tang newspaper.

After a brief discussion, Guo Shao ordered the first drum to be sounded in the Chinese army. The military government also sent messengers to convey military orders to various places.

To the sound of rumbling drums, the felt covering the cannon was lifted, and the soldiers in a queue slowly moved forward. On the ground outside Youzhou City, it is like a huge machine running.

……

To the northeast of the Wenyu River, the seven or eight cavalry of the Zhou army were slowly wandering along a small stream, not far from the other group of horsemen on the opposite side. The light cavalry of the Zhou army was only that the horses were not heavily armoured, but they were also equipped with leather armor; The cavalry was equipped with new plate armor...... It's just that the cavalry that does not wear iron armor on the war horse belongs to the light cavalry.

The horse team on the other side of the creek was more than a dozen Liao army rangers. The two sides did not act rashly or run.

The Zhou army was led by a ten general, and this was the first time he had encountered the cavalry of the Liao army after wandering around for many days, so he did not leave immediately. Both sides watched each other from a distance of about a hundred paces, and neither of them spoke loudly, as if they were both guessing each other's intentions.

The creek is not wide or deep, but it is half as deep as a man, which will definitely affect the speed of the charge, and there are many rocks in the stream.

The lethality of a skilled cavalryman's cavalry is only more than twenty paces, and the body is not as easy to borrow on the horse as it is on the ground. So this distance is very delicate, and you can't have a conflict right away, but you can see each other's every move.

Some of the soldiers were armed with bows and arrows, some with swords and guns, and they nervously watched and rode slowly.

At this moment, I suddenly saw a small group of horsemen slowly approaching from the northwest. Under the sun, the plate armor is reflective, and at first glance it is the Zhou military horses.

The morale of the Zhou army was suddenly greatly boosted, and they were all shaking and ready to try.

"Don't worry, watch." The ten generals observed the distance and distance of their own people, took out a horizontal blow, and played an ugly sound with a coo.

The Liao army on the other side looked sideways, looking at the side of the creek and the horse team in the northwest on the other.

The atmosphere suddenly became tighter, and the ten generals of the Zhou army immediately put away the horizontal blow, carefully pulled out the arrows from the quiver, and said in a deep voice: "Brothers, pay attention, as soon as they turn around and run, they will rush immediately!" ”

He glanced at it, and the two sides were walking to a beach. This section of the stream is extremely secondary, not deep, but also flat and spacious.

"Ready!"

Unexpectedly, there was a sudden shouting on the other side, and suddenly turned the horse's head and charged this way! The ten generals were not mistaken, the Liao army rangers did not run, but rushed over.

The sergeant of Zhou had already "driven" the horse and rushed towards him, and the ten generals no longer hesitated, shouting: "Kill!" ”

The horses sped up, and the horses ran very fast, and soon stepped into the stream.

The white waves suddenly splashed, the ten generals widened their eyes, their whole bodies tensed, and quickly pulled the bowstring, aiming at a Liao cavalry at the front, "Bang!" "A string sounded. hit the target, but the opponent did not fall off the horse, the distance was still a little far, and the arrow shot on the opponent's armor.

After a few moments, the strings crackled and crackled. The arrows clanged on the armor of the Zhou army.

Without saying a word, the ten generals hurriedly put away their bows and pulled out a slender saber from their backs. The shouts of killing suddenly roared.

"Bell!" The ten generals saw the sparks flash in front of them, and the swords collided, shaking the tiger's mouth numb. The blade is slammed.

Immediately, a scream sounded, and a Liao cavalryman smashed a Zhou soldier on the shoulder with a bronze bone (blunt weapon), and the Zhou sergeant fell off his horse. The two sides interspersed each other and rushed through each other, and the sound of struck sound from time to time.

A knight of the Zhou army stabbed the cavalry with a horse lance, and swept the cavalry of the Liao army, the horse lance was heavier than other horse weapons, but he didn't expect to shoot the cavalry of the Liao army off the horse, the guy turned sideways, eased his strength, and was stunned that he didn't fall off the horse, and sat back on the saddle very flexibly.

"Ahh A scream. At the moment when the ten generals flashed a horse, they seized the accurate opportunity to shoot their swords, slashed a Liao army, and then rushed through, leaving only the blood on the knife edge to fly in the wind.

Soon the two armies staggered, and the rest of the Zhou army hurriedly stabilized their horses and rushed forward, stopping to turn their horses' heads. The ten generals hurriedly took a look, and in one confrontation, they lost three horses, all of them were injured and fell off their horses, and they were still struggling in the stream. Eight cavalry lost half of it, while the Liao army was only hacked to death and wounded one.

The Liao army has doubled its own.

The seven or eight cavalry Zhou troops in the northwest of the "Rumbling ......" accelerated their reinforcements. The Ten General quickly turned his head to look.

Someone hurriedly said: "Wait for the reinforcements to come up later!" ”

The ten generals looked at the three wounded cavalrymen in the stream, and the Liao army had already turned around and began to rush again.

The ten generals hurriedly said: "If you leave now, the three brothers will be hacked to death first!" There was no time to weigh at all, and the ten generals shouted: "Kill!" ”
