Early the next morning, Chen Xian was called up again by the guards according to his orders.

Today is the day of the test gun.

This time, the test cannon was not the test cannon cast with blister copper before, but the cannon cast from refined copper and refined tin, smelted bronze alloy in a ratio of 89:11.

Chen Xian named the 89:11 tin bronze "No. 1 cannon bronze".

There were a total of six cannons test-fired this time, namely two three-pound guns, two five-pound guns, and two seven-pound guns.

According to the data obtained from the previous test cannon with blister copper, Chen Xian found that for artillery, no matter what caliber it is, the rate of fire is not too much, but large-caliber artillery has more advantages in range and power, so large-caliber artillery is more efficient on the battlefield.

Of course, it is not that the larger the caliber, the better, the caliber is too large, the mobility will be affected, after testing, Chen Xian found that the gun carriage made by himself at the level of craftsmanship of this era can only withstand seven catties of guns at most, if the caliber is increased again, the strong recoil of the gun will quickly damage the gun car when it is fired.

From this day on, the woods north of Xinzhuangzi continued to hear the rumbling of cannons.

Some of the soldiers were sent to the test range to assist the artillerymen in measuring range, building target groups, mapping shell trajectories, transporting shells and gunpowder.

I don't know if it was lucky or unlucky, Bai Yuanliang's team was transferred to the test artillery site to assist in the construction of the target group.

The so-called target group, in fact, is in front of the cannon, erect a pair of pairs of wooden poles, between the wooden poles are installed a large piece of thin plank, when the cannon is fired, the shells will penetrate a series of wooden boards, by measuring the height of the bullet marks left by these shells and the distance from the muzzle, you can roughly depict the trajectory of the shells.

By collecting shell trajectory data and the corresponding muzzle elevation angle, you can summarize the trajectory and effective range of shells of different caliber cannons at different elevation angles.

In fact, Chen Xian knew that he could roughly calculate the trajectory of the trajectory by using quadratic functions, but he did not intend to teach such advanced things to these students, because it was impossible for these students who had just learned addition, subtraction, multiplication and division to understand such complex mathematical knowledge.

Through this kind of data collection and induction, students can also exercise their positivist spirit.

On the artillery field, Bai Yuanliang was both happy and painful to get in close contact with the cannon, he observed the whole process of the cannon from charge to launch, and quickly figured out that the cannon was filled with gunpowder and shot out of lead bullets, except that it was much larger, it was not much different from the arquebus.

The front-loading cannon is actually such a simple thing, and Bai Yuanliang quickly figured out this seemingly mysterious thing.

A few days later, a letter was transferred from Bai Yuanliang to his brother, who came to visit him, and then to Bai Bingwen, and finally sent by the Bai family caravan to the Baifu ...... in Xizhuangzi.

When the letter was delivered to the Baifu of Xizhuangzi, Bai Shijie had already left, and he took a large amount of gold and silver from the Bai, Tang (two families), Li, and Xu families of Xizhuangzi and Tangjiazhuang, and the hundreds of people from the five families escorted the team and also watched, leaving Yiyuan and heading to Dongping Mansion City.

After reading this letter, Bai Shijun, a white officer, also felt that this news was very important, so he personally took the letter to his brother's study and pressed it on his desk with a paperweight, thinking that he would see it as soon as his brother returned.

……

For some reason, not long after Bai Shijie left Xizhuangzi, Bai Yuanwai gave lanterns to every family, asking every family to light the lanterns at night, saying that it was because he dreamed of his deceased mother.

Although the dealers were reluctant to waste lamp oil, no one dared not listen to the orders of the white staff.

On the second night of the second day, Bai Yuanwai severely punished a few households that did not light lanterns, and no one dared to slack off.

……

Bai Shijie took a large amount of gold and silver to Dongping Mansion City, first exchanged it for money, and then each of them did what they liked, and bought various valuable gifts in different categories, and then began to act in the officialdom of Dongping Mansion.

Because he had explored the road before, this activity came naturally, from Dongping Mansion Yin and Shandong Road Soldiers and Horses Commander and Tianping Army Festival Envoy Wanyan Chengzong (Jin Guofu Yin is generally concurrently the Commander of the Soldiers and Horses of the Road, and concurrently serves as the Commander of the Military Festival of the City and Town of the Mansion), to the various fierce Anbo under the Tianping Army, all of them went through.

In the end, Wanyan Chengzong agreed to send one Meng'an cavalry and two Meng'an infantry troops to Yiyuan to suppress the bandits.

This amount of army mobilization is already the limit of Wanyan Chengzong's private mobilization of large armies.

On this basis, Bai Shijie won the three most elite Meng'an in the Tianping Army.

Among the three Meng'an, Ma Jun Meng'an is the most elite.

This Ma Jun Meng'an is the Hezha Meng'an of the Tianping Army, that is, the pro-army, and its Meng'an is extremely strong is Wanyan Pingtao, the eldest son of Wanyan Chengzong, in order to invite this elite, Bai Shijie spent a lot of money.

These three Meng'an are the elite of the Tianping Army, among which the Ma Army Meng'an is a rare full-fledged Meng'an in the Jin Army today, and there are seven or eight hundred people in the two infantry Meng'an.

After Yan Pingtao led the three Meng'an armies to pull out, Bai Shijie took the lead and rushed back to Xizhuangzi non-stop.

Back in Xizhuangzi, Bai Shijie mobilized the five most elite generals of Bai, Tang (two families), Li, and Xu non-stop and assigned the tasks one by one.

In the evening, a team of more than 20 men in strong clothes, led by two woodcutters, quietly left West Zhuangzi and got into the woods northwest of Zhuangzi.

This night, Bai Shijie, who has always been calm and calm, seemed a little restless, he drove away the new lady who was like glue, and fell asleep alone, but he tossed and turned, unable to sleep, and finally fell asleep and was awakened again.

In the second half of the night, Bai Shijie, who couldn't sleep, simply got up in his clothes and swayed in the black-lit garden.

He walked restlessly back and forth as he looked out into the shadowy mountains to the northwest, as if there was someone or something he cared about.

Before dawn the next day, Bai Shijie came to the main hall of Baifu with two big black circles under his eyes, drinking tea and waiting for something.

After drinking a belly of hot tea, people don't sweat in winter, and the water they drink soon turns into urine.

In the morning, Bai Shijie went to the toilet four or five times, and when the sun had already risen, Bai Shijun yawned and walked into the main hall.

Seeing his brother who hadn't woken up yet, Bai Shijie said angrily: "At such a time of life and death, the eldest brother is so calm and relaxed, the younger brother really admires it." ”

Bai Shijun smiled awkwardly and said, "You have the fifth brother in everything, I'm worried about what's the use." ”

Bai Shijie couldn't help shaking his head angrily and funny, there was nothing he could do with his lazy and confused big brother.
