Five days later, incense was placed on the river, three animals were placed, and a grand sea festival was held headed by Gao Fuji, and the first sea ship was officially appointed as the Conch.

With the old captain's order, the sailors raised their sails, and the Conch slowly sailed out of the dock and headed out for the eastern sea. The Conch will sail along the coastline to Qiongzhou, circle the island and then turn back to Hangzhou, which is planned to take half a month.

Coming out of the mouth of the Qiantang River, the old captain immediately ordered the full sail to be raised, and under the blowing of the sea breeze, the conch was like a sharp sword, cutting through the thorns and waves, and crisscrossing the sea.

After sending off the Conch, Gao Fuji came to the blacksmith workshop, and the steward of the blacksmith workshop was surnamed Tie, which was also an ancestral craft.

"Sir."

"Uncle Tie, are the fetal membranes ready?"

"It's been done, this is the sixth time, the pouring was completed last night, and you can go to the mold right away, and after many attempts, the strength of the gun body is basically free of sand holes."

"That's good, can you test the cannon today?"

"In view of the frequent bombing of the previous two chambers, this time I am going to put alloy steel in the chamber of the gun, and wait another three or four days."

"That's fine, I have to prepare here, and after four days, let's go to the mountains to test the gun."

The blacksmith nodded solemnly in agreement.

After coming out of the blacksmith shop, Gao Buer went to the gunpowder workshop, which was specially arranged on a cliff near the river, far away from the people, and he was not satisfied with the explosive power of the black gunpowder, so he added sulfur and saltpeter to it, although the intensity of the explosives increased, but the stability had not yet been overcome.

Four days later, before dawn, Gao Buer led people to meet the blacksmith and others at the entrance of the village, and a group of people drove three ox carts covered with oilcloth and quietly walked deep into the mountains.

After walking for a long time, he came to a mountain col, and the blacksmith asked Gao Fuji: "Master, I wonder if it is possible here?" ”

Gao Buer nodded and asked, "Did you send someone to see it, are there people around here?" ”

"Two days ago, someone was arranged to see it, and there was no one within a radius of forty or fifty miles."

"That's good, you are going to pull out both guns, this test gun, mainly depends on the quality of the gun body, the firing range and the power of the shell."

The blacksmith nodded, and arranged for his subordinates to begin clearing the site and setting up artillery positions.

In order to adapt to field training, Gao Fuji also made a simple military shovel.

Under the command of the blacksmith, the servant filled the sack with sand and gravel, and built a waist-high half-moon cannon array on the two cleared fields, because it was only the experimental stage, so Gao Fuji did not put the cannon on the gun carriage, the blacksmith himself set up the gun, adjusted the position, and then asked everyone to take a hundred steps back, leaving only one loader, one gunner and one overseer.

Everything was ready, and the overseer sent an ignition signal to the blacksmith, because the gunner and the other three had soundproof earplugs placed in their ears, so Gao Fuji had to invent the flag language to transmit information.

The blacksmith looked at Gao Fuji and waited for him to give the order.

Gao Buji nodded at him and said, "Light the fire, everyone cover their ears." ”

The blacksmith gave the order to ignite, and the gunner immediately lit the fuse on the cannon body with a torch, and the fuse emitted a screeching sound of "呲-呲-呲", which stimulated the nerves of the crowd.

Suddenly, there was a muffled sound of "heavy-" life, and I saw a fire dragon rushing out of the cannon, and then there was a trembling sound from the mountainside facing the 800 paces, thick smoke rose, and rubble flew.

When the smoke cleared, everyone stepped forward, Gao Buer looked at the muzzle, but it was a little blackened, the cannon body was not damaged, and he touched it with his hand, and the cannon body did not heat up significantly, so he could repeat the cannon, Gao Buer nodded with satisfaction. Then the crowd rushed to the hill where the pit had been blown out.

Standing on the deep pit with a diameter of three meters and a depth of about one and a half meters, everyone was terrified and shouted that this was a miracle.

Gao Fuji and the blacksmith whispered a discussion.

"Uncle Tie, I looked at the trajectory at the moment of the cannon just now, basically it just hit the target at the highest hit, let's take someone to measure it and see how to calculate the maximum range."

"What the owner said is very true, I don't know what data the owner wants?"

"You only need to know the distance from the artillery array to the foot of the mountain and the distance from the center of the battery crater to the foot of the mountain, and then calculate it with trigonometric functions, and you can probably estimate the maximum range."

"Trigonometry?"

Seeing that the blacksmith was puzzled, Gao Buer said mysteriously: "It's a new algorithm, I'll hand it over to you in a while, and let someone bring paper and pencils, and bring my special protractor." ”

Hearing that Gao Buer wanted to teach himself a new algorithm, the blacksmith immediately went to arrange it energetically, tossed for a long time, and the data that Gao Fuji wanted was taken by the blacksmith, and then Gao Buer drew sketches and various symbols on the paper, and through calculation, he predicted that the firing distance of this cannon was about 1,400 steps, which was already very remarkable, and it was simply the power of the gods.

Then Gao Buji commanded people to shoot continuously, and when the sixth medicine was loaded, it was no longer possible, although the barrel was constantly cooled down with cold water, but under the action of gunpowder, the temperature of the gun body was too high, in order to avoid accidents, Gao Buji stopped the experiment.

Overall, the first test of the cannon was still unsatisfactory, and Gao Fuji was very satisfied, but due to the limitation of iron-smelting technology, the cannon body could only do so much.

When everyone returned to Zhuangzi, Gao Buer asked the money housekeeper to set up a banquet to reward the people who had worked hard for nearly two years.

Because gunpowder and these things are big killing weapons, so to the banquet in addition to the money steward, Xiao Yumei and Su Xiaoxiao two ladies, is involved in the development of the people, since the beginning of the beginning of the signing of the confidentiality agreement, wives and children parents asked, said that the owner of the farm is researching new farm tools, there is a plough in front, so people do not believe it.

During the banquet, the blacksmith headed the toast to Gao Fuji and said: "The owner, now that we have succeeded, I also ask the owner to set the name." ”

Gao Fuji picked up his wine glass and said: "This thing will bring peace to our Zhuangzi, and at the same time, in the future, we will drive a warship to crisscross the stars and seas, and this thing will definitely become a big help for us. ”

When everyone heard this, they shouted: "The owner of the village is wise." ”

"In order to reward everyone for their merits, I have discussed with my wife that each of us will be rewarded with twenty strokes to thank everyone."

And they all shouted thank you, madame. The two daughters accompanied Gao Fuji to raise a glass together, and everyone drank freely.
