He and Yu Bo tested a lot of equipment, many things Xing Chen had never considered, were created by him.

For example, in the detection technology of Originium technology, Xing Chen had only just come up with the technical concept, and he had already made it into a signal sensing device.

If placed on drones or missiles, the electronic jamming methods commonly used by humans would be useless.

"Xing Chen, why do your missiles and drones always have a thin wire connected to their rear?"

Theresa, controlling a drone equipped with an Originium technology probe, accurately hit the target under electronic jamming.

When she looked up and focused on observing the drone Xing Chen was controlling, she found a transparent thin wire connecting the drone to the operating end.

Using a wire... to control unmanned equipment?

"If Originium energy could be mass-produced, then all of Western Great Power's electronic jamming pods would become scrap metal. For anti-jamming, it's basically unrealistic for missiles and drones to carry hundreds of kilometers of optical fiber," Yu Bo said to Xing Chen while retrieving the optical fiber, "Do you guys have any breakthroughs on the cause of Originium?"

"Didn't I tell you? I picked it up by the river. It's probably an ancient meteorite that fell and was then eroded by flowing water and brought to the surface."

After listening to Xing Chen's explanation, Yu Bo shook his head, "I don't think that's very reliable. I've already sent people to search the entire river, including the riverbank, and didn't find a single speck."

Xing Chen glanced at Theresa, who directly shook her head.

Indeed, if Originium were just an energy mineral, it would be fine, but there's also the Internalized Universe involved.

The Originium in their hands was stable, but who knows if Lao Pu was brewing something big, like reversing the future.

"Is this matter very urgent?" Xing Chen remembered that the islanders had also brought Originium before and almost blew himself up.

"Northern Country, Western Great Power, and the island country all have Originium discoveries, but their Originium is very... unstable. According to my way of thinking, there's basically no usable method."

Well, it was a bit urgent, but not by much.

After completing the test mission, the next day, they took Xing Chen and Theresa on a tour of the camp as agreed.

This base had no female military units, so as soon as Theresa appeared, she attracted a lot of attention.

Of course, everyone just looked and continued with what they were doing.

The group went directly to where the tank commander stayed yesterday. At this time, he was leading people to maintain the tank's anti-aircraft machine gun.

The disassembled and reassembled machine gun was placed on the ground, and the engineering equipment had been taken away by another tank crew. He was wondering whether to have someone carry it up.

"Do you need my help?"

Seeing Theresa arrive, the tank commander quickly had someone call over the people from the other tank crews.

"Of course, but you'd best be careful, a bump or scrape isn't just a scratch..."

Before the tank commander could finish his sentence, she picked up the heavy machine gun with one hand, jumped directly onto the turret.

"Can I just put it here?"

"Alright, alright, hey you, hurry up and mount it."

"Um, can I try firing a couple of rounds?" Theresa was particularly interested in using a heavy machine gun as a personal weapon.

Kazdel does not lack Originium, but it lacks Originium industrial production capacity.

Otherwise, why would so many Sarkaz mercenaries go to the battlefield with large iron plates?

If gunpowder weapons could be introduced, the production capacity of casting units originally used to arm ordinary Sarkaz could be reserved for higher-level combat units.

Moreover, the use of witchcraft devices requires training, but gunpowder weapons only require pulling the trigger.

"I'm afraid that's not possible, our ammunition is all accounted for," then the tank commander changed the subject. He had invited Theresa over precisely to help his teammates regain some face, "However, there's a unit doing live-fire training nearby. I can help you ask."

Theresa nodded. At this moment, she hadn't realized that the tank commander wanted to use the combat skills of the neighboring squad to teach her a lesson.

The fact was as Xing Chen had expected; the neighboring squad leader also initially said no because it didn't comply with regulations.

However, if she could defeat his soldiers, he would let everyone in the team spare two rounds for Theresa to practice.

Seeing Theresa's eager expression, Xing Chen quickly pulled her aside.

"If they don't allow it, then forget about it. Also, be gentle with your moves."

"Got it, got it, I know what I'm doing."

The neighboring squad leader picked one person from his team, who was said to have been eliminated from a competition but was considered a 'soldier king' in their unit.

Both sides took their stances, then the opponent feinted a punch, followed by a sweep kick that knocked Theresa down.

The people of Terra are strong, but their body weight is not particularly heavy. Coupled with Theresa's relative lack of close-quarters combat experience as a caster, her lower body wasn't that stable, so it would be strange if she didn't fall from such a move.

"Miss, would you like another round?" Xing Chen helped Theresa up from the ground, and the opponent then asked.

"Again." Theresa became serious, and then she was again feinted by the opponent and thrown over the shoulder.

"Again." Theresa got up from the ground by herself, then was fooled by the opponent's movements and fell again.

Xing Chen and Yu Bo watched Theresa's frustration. They weren't exactly happy, but they always wanted to keep watching, and the loader's earlier lost face was also regained by these few exchanges.

However, the time it took for the opponent to take down Theresa was getting longer and longer. The Demon King was adapting to the opponent's rhythm at an extremely fast pace.

"Bang." This time, the soldier king didn't fool Theresa. His leg kicked Theresa's leg, like hitting a steel pipe.

The girl controlled his leg with her hand, and then the soldier king was thrown out like a chick.

The soldier king was very surprised, but clearly unconvinced. The two sides exchanged blows several more times, and Theresa defeated the opponent faster and faster.

"Send the rest of your people up together. If we drag this out any longer, it'll be lunchtime."

They were all young men, eighteen to twenty years old, how could they stand being told that by a woman?

The result was as expected, a complete crush. Theresa's reaction speed and strength completely overwhelmed humans.

"Hurry up and tell them to stop. I see that some of their legs are in an unnatural position."

Under the persuasion of several leaders, Theresa finally separated from the opposing side, and she got her wish of a chance to shoot.

Watching her single-handedly hold the gun and fire from the hip, hitting every shot, any remaining objections were overcome by her skill.

"Xing Chen, some of them are injured. Knowing they couldn't beat me, why did they still charge?"

"Because of dignity, honor, and responsibility, they are the finest warriors," Xing Chen looked at Theresa, the eighteen-year-old looking Demon King was also a Sarkaz hero, "Even if they cannot win themselves, just exhausting your stamina and creating opportunities for teammates is worth it for us."

Theresa nodded, estimating that in the Battle of Kazdel two hundred years ago, many Sarkaz were probably like this too.

Xing Chen believed that if aliens invaded, the people of Eastern Country and Western Great Power would also unite against the common enemy.

At lunchtime, they ate directly at the mess hall. In addition to the camp's food, there were watermelons sent by the villagers to thank them for their help.

"Your army is really popular."

"Of course, we are the people's army, fighting for the liberation of all humanity."

"Liberation of all humanity?"

"All oppressed people."

Theresa ate her watermelon, not knowing what she was thinking.

"Xing Chen, can your army be deployed in our region?"

"Then you first have to tell me who are the people, who are the oppressors, and who are the oppressed," Xing Chen was not interested in exporting such things, as not every region had such clear relationships as Tara, "Our army is an army with beliefs. To establish a similar existence, we must first find that belief, and to do that, you must first answer the questions above."

"Indeed," Theresa sighed. The Sarkaz now only had the instinct for survival; where would they find belief?
