Half a year later, the number of apprentices under Chu Tian increased to twelve thousand.

A year later, the number of apprentices soared to 58,000.

Three years later, in a heavily guarded valley outside Baigu City, a large blacksmith factory was ablaze. In addition to 200,000 young apprentices, there were thousands of blacksmiths who were already masters of their craft, learning and forging under Chu Tian.

Five years later, the blacksmith factory had doubled in size again, and was able to forge 120 special crossbows, 24,000 sets of Iron Pagoda heavy armor and crooked vest helmets every month.

Chu Tian passed on the assembly line operation method, as well as some more advanced techniques such as hydraulically driven heavy hammer forging, more advanced alloy formulas, and advanced mold one-step forming.

In addition to heavy weapons such as the bed crossbow, iron pagoda, and crooked horse, this blacksmith factory produces hundreds of thousands of fine weapons every month, such as swords, spears, swords, halberds, strong bows and crossbows, as well as crossbow arrows, arrows, iron caltrops, iron chevaux de frise, etc.

The territory of the Da Cang Dynasty stretched for hundreds of millions of miles. Such a vast territory was simply impossible for the Da Cang Dynasty to effectively rule. Therefore, the Da Cang Dynasty adopted the "feudal" system. Except for a large piece of rich territory directly under the dynasty, the rest of the territory was divided into a total of 36 vassal states.

Because his mother was favored, Yuntian was crowned king when he was only a teenager. He was given a territory that was 950,000 miles long from east to west and 680,000 miles wide from north to south, and he ruled over trillions of people.

In such a vast territory, even with the fastest cavalry under Yuntian, the Cloud Leopard Cavalry, running at full speed without armor, they can only travel more than 10,000 miles in a day and a night. To travel from the easternmost to the westernmost part of Yuntian's territory, the Cloud Leopard Cavalry would need to run non-stop for more than three months; to travel from the southernmost to the northernmost part of his territory, it would also take more than two months.

Standing in front of a ten-foot-high iron smelting furnace, Chu Tian held a large cigarette in his mouth, puffing out smoke while muttering to himself: "So, if the territory is too big, if the cultivation is not enough, it will be difficult to fight."

Yuntian himself had reached the Liming Realm and could fly, but apart from Yuntian, only a dozen of his generals had reached the Liming Realm. As for the cultivators in the Anshen Realm, they could not fly and could only travel on two or four legs.

Whether it was deploying troops or transmitting military orders and intelligence, it all took a long time.

Chu Tian couldn't imagine how exciting this battle would be when Yun Tian raised his arm and raised the flag to rebel! The real battle probably wouldn't take much time, and most of the time was spent on the journey.

"So the Heavenly Court's army actually has a camp of relatives accompanying the troops!" Lord Rat huddled in Chu Tian's sleeves and peeked out, saying stealthily, "This is preparation. Everyone has been traveling on the road for thirty to fifty years, giving birth to cubs one after another. When we reach our destination and prepare to go to war, will these cubs be able to wear helmets and armor to participate in the battle?"

Chu Tian wanted to laugh out loud at the scene imagined by Master Shu. He accidentally inhaled a mouthful of thick smoke into his lungs, and immediately choked and coughed repeatedly.

This cigarette was made from wild tobacco that Chu Tian found in the forests of Dacang Mountain and dried himself.

Because of Chu Tian's preference, this cigarette was imitated by many master blacksmiths, and gradually it became a trend. Beside the several large iron melting furnaces near Chu Tian, ​​one could see hundreds of shirtless blacksmiths puffing out smoke, looking very happy.

Chu Tian casually threw the cigarette butt into the furnace, straightened his body, looked at the boiling hot molten iron gushing out of the slowly tilting furnace, and murmured: "Master Rat, you and I can't stop this war. When I sensed them flying over my head that day, I knew we couldn't stop them."

"Oh my god! Is this how they harvest souls? Start a war in the secular world and use war to harvest lives and souls?"

Chu Tian shook his head and whispered to himself: "War in the cold weapon era, if it lasts too long, I'm afraid too many people will die. So, let me speed up this war, maybe, fewer people will die?"

Lord Rat didn't say anything. After a long while, he murmured, "This makes some sense, but also a little... hypocritical!"

Chu Tian laughed dryly a few times. He raised his head and looked at the white clouds sliding smoothly across the sky. He whispered, "It's a bit hypocritical. I actually want to become a god in heaven. I want to see what heaven is all about."

Licking his lips, Chu Tian said softly, "Only by joining the Heavenly Court and gaining a certain position in it can I get the information I need! It's not like I have to go to the boundless world and find a Heavenly General to beat him up or torture him, right? They explode all the time, and I can't get the information I want at all."

Master Shu shuddered with fear and muttered to himself in a low voice: "Brother Tian, ​​don't be impulsive. It's not comfortable to be chased by those mad dogs!"

All the hair on Master Shu's body stood up. He said sincerely, "It's too uncomfortable to be chased by those winged bird-men and mad dogs. So, it's better to sneak into the Heavenly Palace. I think this boy Yuntian is not bad. We have made some friends over the years. Let's give him a hand!"

Regardless of whether it was true or false, Yuntian had been particularly affectionate and close to Chutian in the past few years. Every three to five days, he would reward Chutian with some rare treasures, some fine wine and food, or some beautiful maids.

In this valley, in Chu Tian’s mansion, there are already four or five hundred young ladies with beautiful eyes and eyebrows.

"Well, Master Rat, you are right. Although some treasures are hard to enjoy, such as those maids... However, this favor is his."

Walking to the forging workshop nearby, under a huge shed made up of steel support structures, Chu Tian's disciples were constantly assembling ferocious and powerful steel crossbows on the assembly line.

Basically, it takes five breaths for a steel crossbow to be assembled at the end of the production line and delivered to the hands of the quality inspection apprentice.

These apprentices skillfully pulled the crossbow strings, put on the crossbow arrows, and shot at a row of targets at the end of the workshop. Sparks flew from the iron targets, and each crossbow arrow sank deeply into the target.

In the past few years, the earliest batch of apprentices who followed Chu Tian had already achieved great success in practicing the Nine Revolutions Heavenly Furnace Method. Many of them could exert a force of more than 100,000 kilograms with just a wave of their arms. This level of cultivation, in the Great Cang Dynasty, was only achieved by the elite imperial guards.

There are also some elite disciples who are specially trained by Chu Tian. Their arms have a strength of one million pounds, which is comparable to the strength of the core generals under Yun Tian.

The strength of Chu Tian and Yun Tian is increasing little by little.

Every set of weapons and every set of armor that Chu Tian passed out increased Yun Tian’s strength by one point.

Before you know it, time flies by.
