The dust and smoke dissipated, and a gap about a foot wide appeared in the camp wall of the Shuozhou military camp, and Chen Ying was stunned and said: "Hold the grass, this is too exaggerated, right?" ”

Although the camp wall built by the Shuozhou military camp is made of rammed earth, it is not one person high. However, it is about one foot eight inches thick, and the railing bones of trees with the thickness of the bowl mouth are used inside, and then they are compacted layer by layer with soil, which is extremely strong, and it is not easy to collapse even if the horse gallops at high speed. However, this stone cannon went down and smashed such a large piece.

Chen Ying walked to the gap in the camp wall and took a closer look. After the stone bomb crashed into the camp wall, the remaining momentum was not completely eliminated, and after breaking through the wall, it rolled out more than ten steps away. And the most surprising thing is that the bowl of thick pine wood in the camp wall was actually broken by Qi.

But imagine that once this stone bullet is not smashed on the camp wall, but on the human body, I am afraid that it will be stained with both death and death.

Zhao Boying said: "So powerful? ”

Xu Caifu said: "What a powerful cannon, hitting three hundred and fifty steps away, it is stronger than the eleventh cannon." ”

Guo Rui retorted: "It is more powerful than the thirteen cannons, the thirteen cannons need five hundred people to pull, this only needs three or five people, and now hundreds of stone cannons are placed side by side, even if the Yanmen Pass is iron, it can be smashed for him!" ”

The only one in the crowd who was still calm was Chen Ying.

Luo Shixin was dumbfounded: "Okay, amazing, if there was such a powerful trebuchet at the beginning, the Tiger Prison Pass could also be captured!" ”

Speaking of Tiger Pass, it was the sad place of the Wagang Army. At the beginning, in order to attack the Tiger Prison Pass, Li Mi attacked for 13 days day and night, and more than 40,000 soldiers of the Wagang Army were buried under the Tiger Prison Pass, and nearly 30,000 people were injured. If it weren't for the fact that the Tiger Prison Pass consumed too much vitality of the Wagang Army, I am afraid that Wang Shichong would not have been able to win easily.

Looking at Chen Ying, Luo Shixin's eyes were red: "If I had known the general earlier, many brothers would not have to die......

Ryazan was dumbfounded and said, "This is too powerful, isn't it?" ”

Zhao Boying's mouth was cracked to the root of his ears, and he said proudly: "The general is really a genius!" Now it will be easier to seize Yanmen Pass! ”

When everyone saw Zhao Boying's sycophancy, how could they fall behind Zhao Boying.

"The general is really wise and scheming, magnificent, bright, upright, wise and brave? , Different customs, do not deceive the dark room, do not forget the ravine, the heart of the child, unparalleled, peerless, Kunshan piece of jade, the dragon among the people, second to none, iron in the Zhengzheng, unsurpassed, the first to raise the head, a generation of romance, the ......best of the mediocre" and other praise words are endless, although Chen Ying clearly knows that they are patting their own ass, but this feeling is indeed very good. Watching everyone dig out their minds

Chen Ying waved his hand again and again to interrupt everyone's compliments, if they didn't stop them, it was estimated that they would be able to shoot their sycophants until dark.

Ge Tong looked at the new counterweight trebuchet seriously and said: "General, this hinge is more troublesome, you see that it has only been launched once, and cracks have already appeared, and it will break at most three or five times!" ”

Chen Ying thought about it and finally found the problem. In the future, as long as the rotating parts are rotated, they all have bearings. Frictional resistance is reduced through the bearings. Chen Ying knows that bearings are not simple, but in this era, it is not easy to make them.

Chen Ying didn't come up with a good opinion, so he asked, "Is there a way for you to solve this problem?" ”

Ge Tong thought for a while and said, "Then you can only use an iron hinge!" ”

After a while, Ge Tong walked to a carriage and took the tools to remove the bearings on the carriage in three or two clicks, Chen Ying was shocked when he saw the bearings in Ge Tong's hands.

Ge Tong actually held a sleeve bearing in his hand, Chen Ying originally thought that the rolling bearing was a product of the industrial era, but he did not expect that the ancient bearing was discovered in the Tang Dynasty 1,400 years ago. This bearing is made of copper-tin alloy, with an inner ring diameter of about four inches and an outer ring diameter of nearly one foot.

Compared with the rolling bearings of later generations, this copper bearing is obviously bulky.

Although this bearing seems bulky, however, it can not surprise Chen Ying. It has been more than nine months since Chen Ying came to this era, and he has never paid attention to these small issues. Through Ge Tong's introduction, Chen Ying realized that this bearing was not actually his invention, but as early as the pre-Qin period, China had manufactured the original bearing shaft type, which was used as a key part of the rotation of horse-drawn carriages or rudders.

Chen Ying carefully observed this bearing, and finally found the difference between it and the bearing of later generations, first of all, the bearing of this era is not the ball as the rolling part of the bearing, but took a steel cylinder about two inches long, about three points thick, and let Chen Ying surprise people, the ancients have realized the role of lubricating oil, of course, the ancients did not have the technology to synthesize lubricating oil, are to take animal grease, as lubricating oil. Sleeve bearings can be said to be the originator of ball bearings.

"Ge Tong!"

"The villain is here, please show the general!"

"Have you ever thought about making this bearing lighter?"

"Lighter?" Ge Tong said with a bitter face: "So that the general knows that if the outer wall of this car is thinned, it will not be durable." ”

Chen Yingdao: "Haven't you noticed that rollers are more labor-saving than balls? If the swivel in this bushing is replaced with a ball, wouldn't the bearing become faster and more flexible? ”

"But it's so hard to make steel balls!" Ge Tong said suspiciously: "Moreover, there is no way to create exactly the same steel balls, even if you are a little old, I am afraid it will be difficult to make dozens of steel balls exactly the same." ”

Obviously, nothing can be done overnight. Chen Yingdao: "In this way, this general wants to set up a Lingzhou military general as a battalion, supervisor Lin Chuanfu as the general as the battalion supervisor, and you as the deputy capital supervisor." For the time being, you can do everything you can to build this new type of trebuchet! ”

Ge Tong didn't react for a long time, and looked at Ge Tong stunned on the spot. Zhao Boying kicked Ge Tong lightly and said, "Don't thank the general for his kindness?" ”

Only then did Ge Tong react, and he knelt on the ground in a hurry, kowtowing to Chen Ying again and again.

Chen Ying said lightly: "Get up, do things well!" ”

Ge Tong got up and said timidly: "General, Xiao Lao'er is the deputy capital supervisor of the general...... Is it an official? ”

"Why aren't you an official?" Chen Ying said solemnly: "Lingzhou will be under the jurisdiction of the battalion supervisor and the division of the army, and now the Lingzhou division is vacant in the army, Lin Chuanfu as a senior official, and also a school inspector to join the army, is a five-grade official." And you, as the deputy capital eunuch, are the deputy of the capital eunuch, and the most recent is also from the sixth rank of the official body. ”

Ge Tong said in disbelief: "Isn't this going to be bigger than the head of the family?" ”

Zhao Boying couldn't help but laugh and said: "The county is only an eight-grade or seven-grade official, even if it is a county official from the famous capital Dayi, at most it is from the sixth grade, and there are only two counties today, but one is from the sixth grade, one is Chang'an County, and the other is Wannian County." ”

"I'm an official?" Ge Tong clapped his hands and laughed: "I'm an official, I'm an official......"

Looking at Ge Tong's arrogant appearance, Zhao Boying's face became darker and darker, and he never thought that Ge Tong fell to the ground with a plop and actually fainted. Everyone was shocked, pinching people again, and pouring water, and finally Ge Tong woke up slowly. Ge Tong, who woke up, slowly climbed up, pulled a person, stretched out his hand and pointed to his collar, and asked eagerly, "Am I an official?" Am I an official? ”
