Soon, Du Yuqi learned a lot of important information from talking with them:

"First, I can return to Earth, and I won't stay there for too long. If the magician Mingxi who summoned me dies, I will return immediately. If she is not dead, then according to the summoning contract signed at that time, my existence will usually not exceed two days.

Second, according to Zhou Qian, some summons appear in the form of projections, such as the Casillas he mentioned earlier. If a projection appears, once the projection dies, the real body will be safe and sound, but will lose part of the soul imprint. However, if the real body appears, then if something happens, it will really die. Obviously, Du Yuqi does not think that he is a projection... so he must protect his life well. "

Third, this seemed to be a place called the continent of Arad. Du Yuqi seemed to have some impression of this name, as if he had heard it at some point on Earth, but he couldn't remember it for a moment.

In addition, the potions that took effect immediately after they drank were made by alchemists, but they also had considerable side effects. First of all, they were expensive, and secondly, it was said that if used too frequently, they would overdraw their own vitality. There were even cases where people who had suffered serious injuries turned their hair white overnight and aged prematurely after drinking the healing potion.

At this time, everyone discussed for a while and thought that although they had lost the main force and the enemy had also suffered heavy losses, they decided to set up camp here. Black Axe swung the giant axe and quickly chopped down a lot of wood. Soon a fence was built around the camp. Then the magician Zhou Qian chanted a spell and added a thick layer of ice on the fence, which was very difficult to climb and could effectively block the enemy from approaching.

After the fence was completed, although Mecca was injured, he struggled to get up. He got a track that seemed to be made of aluminum alloy from somewhere and laid it around the entire camp. Then two machines with unique appearances appeared on the track, which seemed to be running on the track.

Perhaps noticing Du Yuqi's curious gaze, Mecca, with a pale face, smiled at him and pointed at the machine with pride, introducing it:

"EX-730 Viper Cannon, double-barreled, core technology three nanometers, energy consumption reaches an unprecedented five milli-crystals, with infrared recognition function, equipped with double-barreled high-energy machine guns and intelligent recognition system, can effectively identify enemies a hundred meters away."

Then Mecca took out something that looked like a metal box, plugged its interface into the track, and finally took out a small colorless and transparent crystal, but it looked a little turbid, and stuffed it into the control system of the track next to it. Suddenly, a "buzzing" sound began to be heard in the air, and then the EX-730 Viper cannon began to move slowly on the track surrounding the camp.

At the same time, after receiving the energy supply, a cover on the surface of the metal cube began to open, revealing a series of black holes inside. Then, indicator lights flashed continuously, and miniature floating cannons began to fly out from the holes. Mecca introduced with some excitement and enthusiasm in his eyes:

"G17 Predator Paralysis Type, core technology is three nanometers, energy consumption is reduced to only one milli-crystal, there are six of them, they will fly in a random route and at a random speed within a hundred square meters. Once they encounter an enemy, they will stick to it and cause continuous damage to the enemy. The electric current they carry can even produce a paralyzing effect. Once destroyed by the enemy, there will be a very violent explosion."

As he spoke, he began to take out a few things that looked like badges, motioning for everyone to stay put.

"The G17 Predator is not yet intelligent enough, so it can only use micro-capacitance to distinguish between friend and foe. So everyone please carry this identification card with you, otherwise you may be attacked."

Du Yuqi looked at the series of operations performed by Mechanic Mecca and felt overwhelmed. Originally, this place seemed to be fighting with swords. He thought that the level of scientific development was a bit primitive. He never expected to discover such cutting-edge technology.

Then he saw that Black Axe saw that all the defense facilities had been built properly and the surroundings were generally safe, so he sat down on the wooden block next to him, then took off a pair of gloves on his hands and placed them casually aside.

Du Yuqi had long been curious about the pair of gloves on Hei Axe's hands, because the gloves looked very high-end and were made of machines. There were rotating bearings on the steel finger bones, which made a slight buzzing sound. Various sophisticated and complex structures could be seen in the gloves themselves.

After taking off the gloves, Black Axe turned on a switch on his wrist and took out a small, dim, colorless crystal from it. He then threw it on the ground without seeming to cherish it. Du Yuqi asked curiously:

"What on earth is this mechanical glove you're wearing for?"

After hearing Du Yuqi's question, Black Axe laughed and said:

"You're talking about this. It's an auxiliary thing that can greatly increase the wearer's strength. Normally, the threshold to become a priest is very high, because you often have to use heavy axes, heavy sickles, totem poles and other giant soldiers for continuous combat. However, with the assistance of this mechanical glove, the threshold can be lowered."

Du Yuqi suddenly realized and nodded. He asked Black Axe to activate it again, and then he put it on and used it. Sure enough, he found that it was indeed the case. However, the sudden increase in power also made him very uncomfortable. At the same time, Du Yuqi also discovered one thing without anyone reminding him:

He had only been in the Arad world for three or four hours, but from the damaged self-propelled logging mecha at the beginning, to the night protection system he had seen before, to the mechanical glove he was using at this time, they all seemed to revolve around one thing, that is, the crystal block! It felt like gasoline and electricity on Earth, supporting half of the entire civilization.

"Whatever! Now I just need to make it through the next day and then I can go back."

Du Yuqi shook his head and put all these wild thoughts behind him. His attention was quickly attracted by the aroma emanating from the camping pot next to him. He had been in a semi-starved state all the time, and his resistance to food was completely negative at this moment.
