Zhu Shun followed behind to the empty shooting range, the tiger squat cannon had already been placed, Zhao Doumi took a few deep breaths of the late autumn cold wind, trying to calm himself down.

After convincing himself with safety more than a dozen times in his heart, his hands stained with clay moved away from the tiger squat cannon and walked to a four-corner pavilion not far away.

The four-corner pavilion is built very large, and it is said to be a pavilion, but it is more like a tavern lobby without four walls, and forty or fifty people can stand loosely.

The students of the Jingshi University Hall were all anxiously waiting here, with great expectations in their hearts, and on the round stone table in the middle of the pavilion at the four corners were a few steaming Hu Louzi.

The students of Beijing Normal University, who had not eaten three meals, were hungry and 'cooing', and finally they couldn't stand it anymore, so they walked over and didn't wash their hands and casually picked up a Hu Louzi and ate it.

His eyes were still on the tiger squatting cannon, staring at the worker who was specially used to test the parameters of the artillery, one by one wearing chain mail and plate armor, wrapped into an airtight iron can.

Zhu Shun looked at the dusty and muddy palms of the students of Beijing Normal University, and did not feel the slightest dirt, but it was much cleaner than those bureaucratic squires who were poor and luxurious and wanted to carry the mountain spring water from the mountain to wash their hands.

Seeing that the students of Beijing Normal University had finally started to eat, they turned their attention to the shooting range with confidence.

The power of the artillery explosion is very great, and if it is light, it will seriously injure the Liaodong sergeant, and if it is heavy, it can directly blow the Liaodong sergeant out.

At the beginning, there were many ordinary people because the monthly money was as much as three taels, and it was thirty-six taels of silver in a year, and the Daming Arms Company would give a reward for the New Year at the end of the year, as much as forty taels of silver, and enthusiastically became artillery parameter test workers.

Later, after repeated explosions, many test artillery workers were injured, and even one person was blown up and crippled, and many of the test workers only worked for more than ten days before retreating.

Now that the poor family really can't open the pot, and there are middle-aged men with parents, wives and children to support, they will risk their lives to take over this livelihood.

The middle-aged man's family in front of him is okay, but the eldest son is admitted to Xiucai to go to school in the school, and the monthly expenses are too large, so he will risk being crippled to become a test gunner.

In today's world, once you are crippled, you are almost waiting to die, and the imperial court does not have a special donation for the disabled people.

The middle-aged man put on the tin can and began to test the parameters of the artillery, first putting in a small amount of gunpowder to test whether the breech of the tiger squat cannon is brittle and hard.

With a 'bang', the muzzle of the cannon burst into flames, and the barrel of the tiger squat cannon was still black and shiny, without a single crack.

The middle-aged man breathed a sigh of relief, waited until the smoke of the muzzle of the gun almost dissipated, and walked to the muzzle position step by step, carefully observing the chamber of the tiger squatting cannon.

By observing the residue of the dregs, the luster of the chamber wall, the temperature of the body tube, and so on, the middle-aged man can basically conclude that this tiger squat cannon is qualified by virtue of his rich experience in testing guns for many years.

The middle-aged man was wearing an iron can, and his mobility was inconvenient, and he had observed the chamber of the tiger squat cannon, and the next thing was handed over to an apprentice he brought.

The apprentice took out a ** brush, the top was a soft cotton cloth, and after dipping it in water, carefully clean up the gunpowder residue in the gun chamber, as well as some sparks that had not been burned.

Clean up all the gunpowder residues, take out a dry cannon brush to wipe off the water stains that can be left inside, and take out a spiral hook rod to clean up any paper scraps and fiber residues that may exist.

The clean-up process is extremely important, as it is related to whether the gun can fire successfully, as well as the service life of the gun, and will also affect the range of the gun.

The apprentice is the nephew of a middle-aged man, and the nephew who can't read the eight-strand text is very bold.

Since he saw the big explosion of Wang Gong's factory from afar in the second year of Chongzhen, he has become very interested in artillery, and took the initiative to ask his father to let him and his uncle be an apprentice of artillery.

The apprentice can't study, but he is very serious about his work, and his serious attitude makes Zhu Shun feel that this young man is good.

After quickly cleaning the chamber, the apprentice reloaded the gunpowder, inserted the fire rope, and immediately ran away.

There was another loud 'bang', and the tiger cannon fired more gunpowder.

Next, the amount of gunpowder was increased until the sound changed to a 'boom' sound, reaching the normal amount of gunpowder of the Tiger Squat Cannon.

The middle-aged man stopped to rest for a moment, and the apprentice ran over to pull open his uncle's steel armor and poured a few sips of cold water on him.

At the end of the break, the middle-aged man dragged the heavy tin cans and officially began the test launch, which was the service life that everyone was concerned about, such as Zhu Shun, Zhao Doumi, etc.

One hundred rounds.

Three hundred rounds.

Five hundred rounds.

Four days later.

After three or four test artillery workers tested around the clock, the Tiger Squat Cannon broke through the service life of the artillery cast by the normal casting method.

Reached six hundred rounds.

Before the 600th artillery was fired, the students of the Jingshi University Hall, who had been standing in the four-corner pavilion for four days, suddenly did not dare to look at it, and they all turned their backs.

Close your eyes and pray silently in your heart, praying for the blessing of the spirit of the porridge god in the sky, and bless the tiger squat cannon not to explode.

"Master Hou, the tiger squat cannon can continue to fire."

The four-corner pavilion was far away from the test site, and the test apprentice personally ran over to convey the test results of his uncle.

Zhu Shun smiled with relief.

Zhao Doumi and the students of the Jingshi University still didn't turn around, and their backs trembled slightly in the strange eyes of the apprentices.

Choked up with tears.

They have paid too much and waited too long for this day.

From now on, there is no need to see students from other colleges running away, and you can greet those classmates generously.

Tell them.

There has been a breakthrough in artillery research!

Zhu Shun walked over and rubbed the heads of the seventh disciples, instead of comforting him and the students of Jingshi University, crying was a good vent.

looked at the apprentice who was standing next to him and waiting, and said calmly: "Continue to test the gun." ”

The test apprentice got Zhu Shun's order, and he was not stage frightened, gave Zhu Shun a salute, and hurriedly ran back to tell his uncle.

The gunsmiths began a new round of artillery tests.

Six hundred and fifty rounds.

Seven hundred rounds.

Seven hundred and fifty rounds!

Another few days passed, and after Zhao Doumi and the students of Jingshi University, they once again changed into what they were when they first entered the Arms Academy, and their temperament changed from depressed to hearty, laughing all day long.

Just one thing hasn't changed.

Dark circles and scruffiness.

Zhao Doumi and the students of Beijing Normal University would come over every day to observe the test firing of artillery, but they did not dare to watch it some time ago, so they bought a Western clairvoyant mirror and admired the test firing of the artillery with relish.

The pungent smell of gunsmoke.

It has become the most delicious gluttonous meal in the world.
