Traveling through the sword to engage in military industry

With a clatter and a clang, Ren Zhong achieved another return in the cave next to where he had crossed back to the main plane. This time, he tried bringing back six 5-kilogram copper ingots, packed in his specially made transdimensional suit, and as expected, there were no issues whatsoever.

After the system upgrade, Ren Zhong had basically figured out the main function of this upgrade: the ability to cross to a specified location within a ten-mile radius of a natural crossing point.

It was basically as he had expected. Although this function was essentially useless to Ren Zhong right now, easily carrying 30 kilograms of copper ingots made Ren Zhong feel that this was not his limit.

In his mind, he already had a new idea: to customize an even stronger load-bearing suit, using denim fabric to remake a reinforced version of the load-bearing long shirt, with more secure carrying capacity. Ren Zhong could challenge the limit of carrying 60 kilograms at once!

Compared to the exorbitant profits of penicillin, the value of copper was of course much lower. According to the current price of copper in the base area, 2 yuan per kilogram, one trip would only bring 60 yuan, which was the price of 20 doses of penicillin. The cost performance was simply outrageously low compared to penicillin.

But penicillin couldn't directly kill the Japanese devils, while bullets could. Therefore, Ren Zhong decided that until he found an effective source of copper in the Bright Sword world, he would rely on his own efforts to transport this strategic material to the Bright Sword world by any means possible.

It was just that directly purchasing copper ingots in large quantities still had purchasing limitations, as large transactions of these materials would be subject to audits regarding the legitimacy of their use.

Every time Ren Zhong thought of these restrictions, he was extremely envious of other transmigrator colleagues who could purchase without restrictions.

Fortunately, Ren Zhong didn't dwell on it for too long and came up with a solution that wasn't really a solution, which he would implement when he returned to the main plane.

Taking off his special transdimensional long shirt, Ren Zhong returned to the clothing factory in the same down jacket he had worn the first time.

"Old Li, please take care of the work here. I'm going to go out to the mountains and see if I can bring back anything else," Ren Zhong said to Li Yunlong. "The medicine I brought has all been sold to Zhang Wanhe. I see that the base area has a large shortage of supplies. I'm going out to the mountains to see if I can find a way to bring back a batch of supplies that the base area urgently needs."

If Ren Zhong wanted to bring back new things, it wasn't suitable for him to continue staying with Li Yunlong. The previous penicillin could be brought into the mountains alone, and Li Yunlong and Zhang Wanhe could understand that. But if Ren Zhong continued to create all kinds of things under Li Yunlong's nose, it would be inexplicable.

Therefore, Ren Zhong had to leave Li Yunlong's sight, or even the base area's eyes, for a period of time before returning, so that he could bring out new things.

"Old Ren, why so suddenly?" Li Yunlong asked, his small eyes darting around after hearing what Ren Zhong said. "Look, Old Li doesn't have much ability now, and he's trapped in this clothing factory and can't go anywhere. You're leaving, and I don't know when you'll be back. Our August 1st Chemical Factory has only just started laying the foundation. The outside is chaotic with war. Do you want me to send a few comrades to protect you?"

Li Yunlong was indeed very worried about Ren Zhong's sudden departure.

You had to know that although the clothing factory didn't have anything too valuable, it was close to the headquarters. Ren Zhong hadn't yet gained Li Yunlong's trust. Although he had sold the medicine twice, given Zhang Wanhe a way to make money, and saved dozens of seriously injured soldiers, it wasn't enough to prove that Ren Zhong had no problems.

If it was an enemy plot to exchange more than ten thousand yuan worth of scarce medicine for the chance to eliminate a base area headquarters, Director Dai from the mountain city would be willing to pay this price.

Ren Zhong initially didn't understand what Li Yunlong meant. "No need to bother. It's more convenient for me to be alone. Outside the mountains, there are also overseas Chinese organizations supporting me."

"That won't do. There are many soldiers and bandits along the way. Old Ren, you don't have any military experience. How can you deal with these dangers? I'll give you my guard, Huzi. It'll be much safer for you to travel together. Huzi may not be old, but he has a lot of combat experience with me, so I'm more at ease. Besides, there's a secret road in the base area. Old Ren, I'm afraid it'll be difficult for you to find this road out alone."

Li Yunlong insisted.

Ren Zhong came to his senses a little. Huzi was Li Yunlong's personal guard. Even when Li Yunlong was demoted to the clothing factory, he followed Li Yunlong there.

He could be said to be the most trusted of Li Yunlong's confidants. Now that Li Yunlong was insisting on sending someone to follow him, there were probably some other ideas behind it.

Several thoughts flashed through Ren Zhong's mind, and he suddenly understood the key to the problem.

"Alright, I'll travel with Huzi on the way out of the mountains, but when I get to the city, it's safer for me to travel alone. This trip to the mountains may take several days. Once I've straightened out the freight channels, I'll return to the clothing factory. Huzi will wait in the mountain village before I enter the city. When I've taken care of things and come back, I'll find Huzi in this mountain village to go into the mountains together," Ren Zhong said.

Having someone by his side would of course be very inconvenient, but if no one followed him for a while, Li Yunlong would probably be very worried.

His mysterious image hadn't yet earned the trust of Li Yunlong and the others.

What's more, he didn't know the way!

He would have to return to the main plane to check the relevant routes before he could leave the mountains. And after so many years, the current roads and the Bright Sword world had undergone great changes, and he might not be able to find the original main road.

"Okay, let Huzi protect Old Ren to Liuzhuang outside Yuping County. We have a contact point in Liuzhuang outside Yuping County. After Huzi sends you there, he will wait at the contact point for Old Ren to return," Li Yunlong said, seeing that things were mostly settled, and he didn't insist on accompanying him the whole way.

As long as there were no tails following him when he returned, Li Yunlong wouldn't be afraid of Ren Zhong revealing too many secrets.
