Early the next morning, Zhu Shun came to the cannon casting workshop.

Workers are already at work, and the mechanic in charge of maintenance takes a small brush to coat the rows of gears and propeller shafts with a layer of soybean oil, which is used as lubrication to reduce wear and tear on the parts.

After lubrication, rows of gears and propeller shafts start to work, making a 'click' mechanical friction sound.

The fiery red flames came out of the molten iron furnaces in the cannon casting workshop, and they began to smelt iron blocks and cast guns of various calibers.

"Let's go! The artillery was hoisted. ”

"Fasten the chains!"

"Start pouring iron juice."

The shouts of the workers sounded in the workshop, and they began to hoist the heavy Hongyi cannons, tie the chains, and cast the cannons.

The sounds were staggered into an extremely lively scene, and the cannons were constantly transported out of the cannon casting workshop and stored in the warehouse like an assembly line.

If this is replaced by the Imperial Military Bureau or the Bugarao Artillery Factory in Xiangshanao, the warehouse is stocked with all kinds of artillery, piled up.

The Daming Arms Company originally built a huge warehouse with concrete, but it was empty, and the new artillery had just been counted and registered, and before it was transported to the warehouse, it was snatched away by a bunch of stewards of the prince's mansion when it came to the door of the warehouse.

At the door of the warehouse, there is a group of stewards of the prince's mansion who are stationed all year round, in order to compete for a tiger squat cannon of dozens of catties, they can fight, but fortunately, the Daming Arms Company is equipped with a company of riflemen.

Those tall and sturdy riflemen who had been nourished by a lot of meat stood around with doumi-style rifles, so that those stewards of the prince's mansion only dared to fight when they were snatching artillery, and did not dare to really fight.

Zhu Shun was in a very good mood when he saw the hot scene in the cannon casting workshop, and what he cast was not a black and bright cannon, but a key to open the door of Nanyang trade.

Next to the molten iron furnace, Zhao Doumi and the students of Jingshi University still stayed in the cannon casting workshop and did not leave, and they couldn't support it after standing all night, so they casually found a piece of iron, wood, and discarded artillery around and sat on it.

The body left the vicinity of the molten iron furnace, but his eyes were not, a pair of eyes with heavier dark circles, all staring at a tiger squat cannon clay mold.

Wan Ji and a few students from Beijing Normal University didn't sleep for two nights last night, and they couldn't bear it anymore, and they fell asleep lying on a pile of soft straw.

Although the weather becomes very cold after autumn, there are many small iron melting furnaces in the casting workshop, and the temperature is kept at about 20 degrees Celsius, so it is not cold to sleep here.

All of them were snoring soundly, apparently deadly asleep.

Normal people can't bear it if they don't sleep for one night and one day, let alone two nights and days without sleeping.

Zhao Doumi stood next to the clay mold, holding a water ladle in his hand, and slowly poured water into the opening of the hollow core, and the water flowed out from the bottom.

Everyone was looking forward to the end of the cooldown of this gun.

After two sticks of incense, Zhao Doumi couldn't hold it anymore, although he was still wearing a Songjiang purple cloth right shirt, handed over the water scoop in his hand to Wan Ji who woke up, and casually found a soft straw pile and slept on it.

I was so sleepy that I snore loudly after a few breaths.

Zhu Shun saw the enthusiastic look of the students of the Beijing Normal University Hall of the Munitions Academy, and at the same time he was a little sad, and he did not persuade them to go back, after all, for these students of the Beijing Normal University Hall, the clay mold in front of him was everything.

instructed the sedan chair man to arrange for the cook in the dining house to boil some millet porridge as soon as possible, and then take the pickles from Liubiju and send them over.

Until noon, the cannon cast by the inner mold water cooling method was cooled.

Wan Ji threw away the water scoop in his hand, and the monkey hurriedly began to dig the mud mold: "Hurry up and dig it out, the cooling is complete." ”

The students of Beijing Normal University were sleepy and couldn't open their eyes, and almost all of them were napping half-asleep, and when they heard that the cooling was complete, they all woke up immediately.

'Hula' rushed over at once, and he didn't bother to use a shovel, so he stretched out his hands and went to dig and fill in the soil.

The cylindrical pit was so big, at most there were four or five people around, and other students from the Beijing Normal University Hall who couldn't help stood next to them and scratched their ears and cheeks anxiously.

The students of the Beijing Normal University Hall on the outskirts were even more anxious to circle around the crowd, trying to find a gap to drill into and help dig out the tiger squat cannon cast by the inner mold irrigation and cooling method.

All the students of Jingshi University have this idea, and those peripheral students can only be anxious.

It didn't take long for a piece of dirt to be dug up, and Wan Ji and the three students of Beijing Normal University were carefully carried out as if they were holding their newborn eldest son, and carried them down the cement to the empty shooting range.

This scene looks extremely ridiculous, after all, the mud is wrapped in wrought iron, and the steam hammer can't smash it, let alone fall to the ground.

Zhu Shun couldn't laugh at all, he couldn't even smile with relief, he was only sad.

These enthusiastic students of Beijing Normal University can only serve the country wholeheartedly, and a sloppy person will not even care about his appearance, let alone get drunk like the children of bureaucrats and squires.

Although with their current knowledge, as long as they open their mouths, the little princes who are expanding their territory in Nanyang and trying to establish trade points will hire the students of the Beijing Normal University Hall with endless glory and wealth.

But no one went, not including the balding students in the sulfuric acid lab.

Dedicated to the family and country.

For the nation.

It is a sentence that is interpreted with real actions.

Pifu did not dare to forget the country.
