If you want to make a good bow, the materials you choose are very important. It is impossible to cut a bamboo and tie a rope to both ends. The bow and arrow made in this way will definitely not exert any power even if you have the attributes of the lord Liu Feng.

"Kaogong Ji·Bowman" records that "six materials" are needed to make bows, namely "dry, horns, tendons, glue, silk, and lacquer".

"生" is made of jujube wood, followed by ginger wood, oak tree, etc., and bamboo is the lower one.

The material of these woods is extremely solid and will not be easily broken without being pushed or pulled. The range of arrows is long and lethal.

The materials of the southern bow are obviously different from the northern bow. The south mostly uses bamboo as the stem, while the north mainly uses this hard wood. This is also one of the reasons why the northern army always took the lead in ancient wars.

"Horse", that is, animal horns, are made into thin sheets and attached to the inside of the arch arm (abdomen).

The main bow-making method is to use cow horns, which are white, middle-green, and not abundant. "The horns are two feet long and five inches (nearly 50 cm), and the three colors are not misleading, so it is called cow wearing cows." This is the best horn material (the price of a horn is equivalent to that of a cow, that is, the head of the cow is not a cow horn, but two "cows").

"Rent", that is, the tendon of an animal, is attached to the outside of the arch arm (back).

The functions of tendons and horns are to enhance the elasticity of the bow arm, so that the arrows are more vigorous and fast when they are shot out, and the middle objects are deeper. Among them, beef tendons are the most commonly used "six materials". The tendons should be selected as small as strips and long, and the larger ones should be round, even and moist.

"Glue", namely animal glue, is used to bond dry materials and horn ribs, mainly including six types of glue, including deer glue, horse glue, beef glue, rat glue, fish glue, and rhinoceros glue.

"Silk", that is, silk thread, tightly wraps the bow tube with the corners and ribs to make it more firm.

"Paint", apply the prepared bow arms to prevent the erosion of frost and moisture.

Therefore, it is not a simple matter to make a qualified bow. Now the city cannot get enough materials for making bows, so it is not that Liu Feng does not want to increase the number of bow soldiers. It is really a clever woman who can't cook without rice.

The casualties statistics were quickly sent to Liu Feng. In just one morning of siege, more than 600 people were killed in battle, and 1,300 injured, of which more than 600 were seriously injured. The total casualties were more than 1,900.

It is worth mentioning that the casualties of his direct Black Armored Army were relatively fewer, with only twelve people killed, fifty people slightly injured, and no serious injuries.

Seeing this casualty data, to be honest, Liu Feng didn't know whether it was good or bad. After all, he didn't know anything about ancient wars. He silently calculated that if the average casualty was 2,000 people per day, the number of casualties would reach 44,000 in the remaining 22 days!

Of course, this is just a reference data, and the accuracy rate is probably not even half. After all, the battlefield changes rapidly, and it is impossible to use this method to calculate casualties.

I opened the system and looked at it. When I shot and killed the enemy cavalry yesterday, I had already received 311 merit points. Now it has risen directly to 932 points, which has increased by 621 points at once. This means that 1,242 people died in the enemy today, and the comparison of the number of casualties between the two sides is about 1:2.

Although more than 600 people were killed in battle, Liu Feng's combat power has actually increased instead of decreasing.

Looking up at Yang Rong who was standing there bowed, he put down the booklet in his hand and asked, "What do you think of today's battle?"

Yang Rong felt nervous and did not dare to neglect, and quickly responded: "Reported to the lord, most of our soldiers went to the battlefield for the first time. They developed fear and fear of war in the war, so the number of casualties was inevitably larger. Among the more than 600 people who died in the battle, more than 100 of them were killed by the supervisory team behind them because they escaped the enemy's arrow rain. Some of the casualties were too panic, and they stepped on each other and even fell directly from the city wall. As long as they survived a few battles, the situation of the soldiers would be improved."

"Um."

Liu Feng nodded. He knew very well how good the soldiers on his side were. To put it bluntly, it was a group of farmers who had just picked up spears. If they were not defending the city, but fighting in the wild, they would probably not be as simple as this number of casualties, but were directly defeated. After all, the other party had an elite cavalry with thousands of people.

Not to mention these regular soldiers who had just transformed from hungry people, even the bandits in his hands were not the opponent of the cavalry when they were in the field.

Liu Feng's current strength is still a very weak existence compared to the Dagan Dynasty.

At the same time, in the central army tent outside the city, General Xuanwei Yang Zong also obtained today's casualties, with more than 1,200 casualties killed and 1,500 injured. After all, in that case, even the seriously injured could no longer come back, and the total casualties were less than 3,000.

This number of casualties is nothing in his eyes. In the past, when fighting on the border, it was common to kill three or five thousand people in a battle. Sometimes even tens of thousands of troops were wiped out, and he was already numb.

Through today's tentative attack, Yang Zong also observed carefully for a while while on the lookout, and found that the traitors in the city, except for the strange archers, were nothing more than a mob, and it was not to be afraid.

If they were not defending the city, they were in the wild, and he was confident that he could defeat these traitors with just one charge.

Therefore, the biggest difficulty that Yang Zong is facing now is the tall and thick city wall in Yinyang County. So far, if you want to break through this city wall in a short period of time, you have not come up with any other way except to fill it with human lives and smash it with siege equipment.

Looking at the tall city wall ahead, Yang Zong couldn't help but sigh. Facing such a strong city, he felt helpless, "It would be great if there were internal supporters in the city."

Thinking of this, a sudden flash of inspiration in his mind, he suddenly turned around and walked to the desk, picked up the brush with the ink marks, quickly wrote a letter, and then stamped his own seal at the end.

"Come!"

After putting the letter into the envelope, Yang Zong shouted outside. As a result of a trembling sound of armor, a soldier covered in armor walked in from outside and bowed, "General!"

"You send this letter to the prefecture and hand it over to the people from the secret inspector's office."

"Yes! General!"

After receiving the letter, the personal soldier immediately retreated, then rode a fast horse and quickly left the camp.

Next, Yang Zong refused the request of all the generals to fight on the grounds that there was not enough siege equipment, and stayed in the camp with peace of mind. While urging craftsmen to build siege equipment, he waited for news.

The people in Yinyang County were not idle either. They treated the injured, repaired the destroyed city walls, collected materials for defending the city, and began to prepare for the next time to defend the city.
