The one on the left is a printer, specifically used for printing things; the one in the middle is a communication machine; the two communication machines can be combined to enable communication between each other; and the one on the right is an industrial machine tool.

The birth of the new iron smelting furnace meant that Xinluo City was no longer short of steel, but the efficiency of processing various parts from steel could not be improved.

This is because the method used in Silla City to process various parts is still by hammering, which is extremely inefficient.

This problem can be solved with industrial machine tools.

Industrial machine tools can manufacture a wide variety of lathes, thereby greatly improving the efficiency of machining parts and achieving a qualitative leap.

But whether it's a printing machine, a communication machine, or an industrial machine, they are all still just concepts and have not yet become a reality.

Achieving all three is not an easy task.

"Zijing, call Qing'er over," Ye Feng said without looking up.

"Okay!"

Zijing responded and then transformed into a black shadow and disappeared.

About ten minutes later, Luo Qing arrived.

"Ancestor, you called me? Have you come up with some new gadgets again?" Luo Qing asked Ye Feng curiously.

Night Breeze smiled and nodded, saying, "Take a look at these three things."

Luo Qing then ran to Ye Feng's table and carefully examined the design drawings in front of him.

Luo Qing became more and more surprised as she looked at the three design drawings, because the inspiration in them was very novel and she had never seen anything like it before. Moreover, the ingenuity of the designs completely exceeded her imagination!

"Ancestor, you came up with all of this? That's really amazing!" Luo Qing looked at Ye Feng with admiration.

Ye Feng chuckled and said, "Don't just admire me. These three things are the tasks I've assigned to you. Now, you'll study these three things. If you can turn them into reality, then our Xinluo City will become stronger than before, and its development speed will greatly increase!"

"Yes, Ancestor." Luo Qing nodded vigorously.

Ye Feng added, "By the way, go talk to your aunt and ask her to recruit some skilled craftsmen who are good at building ships."

"Building ships? Ancestor, you want to build ships?" Luo Qing asked again.

"Nonsense, our wave cannon has been successfully developed, and it was designed from the beginning to be mounted on ships as naval guns. How can we do without ships?" Ye Feng said irritably.

Luo Qing nodded and said, "That's true. I'll go talk to my aunt about it later."

"Go."

The night breeze waved goodbye.

After Luo Qing left, Ye Feng continued to sit behind the table and think, while Zi Jing tilted her head and stared at Ye Feng without blinking.

"Why are you staring at me? Is there something dirty on my face?" Night Wind asked.

Zijing immediately said, "I'm just curious why you have so many wonderful ideas that I've never had before. What exactly is in your head?"

Night Wind chuckled and said, "That's just because I'm knowledgeable and experienced."

Suddenly remembering something, Ye Feng asked, "How's the expansion of the infantry corps going?"

“This is not my responsibility, how could I possibly know so much?” Zijing immediately shook her head.

"You can't be completely ignorant, can you?" Ye Feng asked.

Zijing thought for a moment before saying, "These past few days, Chen He and Jiang Wei have been busy expanding recruitment, and the commoners and serfs in the city have been enthusiastically signing up. I think this matter must be going very smoothly. Moreover, if any trouble were to arise, Chen He or Jiang Wei would definitely ask you for help, but they haven't come to you yet, which is enough to show that there are no problems with the infantry corps."

As luck would have it, just as Zijing finished speaking, Chen He's voice came from outside.

"Ancestor, are you there? I have something to report to you."

Chen He's loud voice can be heard clearly even from hundreds of meters away.

Night Breeze smiled and said, "I'm here, come in."

"Yes, Ancestor."

Chen He then lifted the tent flap and strode in. He glanced at Zijing, who was eating melon seeds, and then turned to Yefeng, saying respectfully, "Ancestor, the expansion of the infantry corps is basically complete. The infantry corps now has a thousand soldiers and about eight hundred new recruits."

"They've expanded enrollment by so much?" Ye Feng looked surprised.

Ye Feng originally thought that Chen He and Jiang Wei could recruit about 500 more people.

After all, Xinluo City is still under construction, and manpower is needed in various places. Even if those commoners and serfs are willing to join the infantry legion, Luo Lin, Luo Qing, and Zhao Bo will definitely not agree to release them.

If everyone goes to the Legion, there won't be enough labor.

Seemingly guessing what Ye Feng was thinking, Chen He said with a smile, "Ancestor, you don't know, Wang Qian and Wang Qiang's recruitment of refugees is going very smoothly. In the past few days, several thousand people have gathered from all over the place. Moreover, the affairs department established by Ms. Luo Lin has arrived in Huasheng City and sent a large number of civilians and serfs from Huasheng City."

"So now, the total population of our Silla City has reached 20,000! Excluding the elderly, weak, women and children who are unable to work, there are at least 15,000 young and middle-aged people!"

As soon as Chen He finished speaking, Zijing let out a "Wow!"

"That's incredibly fast!"

The Bauhinia tree cannot help but be deeply moved.

You should know that when she came to the Death Mountain Range with Ye Feng two months ago, there were only 1,300 people in total.

In just two months, the population increased from 1,300 to 20,000, which is an incredibly exaggerated speed!

"Is there enough food?" Night Wind asked.

An increase in population leads to an increase in the labor force, which is a good thing.

However, population growth will also put a heavy burden on food supply. After all, more than 20,000 people means more than 20,000 mouths to feed. If each person eats one kilogram of grain a day, then 20,000 kilograms of grain will be consumed every day.

That's no small amount!

Chen He smiled and said, "There is no problem with food. Although Director Zhao's agricultural department cannot provide food due to the short time, Ms. Luo Lin is purchasing food from Jiangxia City, Huasheng City, and other cities. So feeding more than 20,000 people is not difficult."

Hearing Chen He say that, Ye Feng finally breathed a sigh of relief.

In any case, Silla City must not allow a situation to occur where it attracts commoners and serfs but cannot guarantee that they will have enough to eat.

Once this happens, it will be very difficult to recruit refugees from other places later.

"Ancestor, I'd like to ask when the fully automatic explosive rifles for those eight hundred new recruits will be delivered?" Chen He asked, rubbing his hands together.

It seems that this was Chen He's real purpose for this trip.

Ye Feng smiled and said, "You should go to Luo Lin about this. Luo Lin is the director of the Logistics Support Department, so this is under her jurisdiction."
