After a few hours......

Ling Xingyu didn't know how long he had been soaking in the water, anyway, it was already dark before he dared to swim out of the reeds. Fortunately, the water level in this area is not high, otherwise he would have lost his strength after hiding in the water for so long.

"Woo!" After Ling Xingyu climbed from the water to the shore, he was drenched and climbed up the riverside walkway. He looked around slowly, only to see that it was pitch black, and the street lights had no electricity, so he could only observe the situation around him through the moonlight.

The surroundings were very quiet, and it didn't look like there were people at all.

Ling Xingyu clutched his chest and left the riverside walkway. Then I walked to the road and came to the side of a small car. Then, Ling Xingyu opened the trunk of the car again, and what was placed in the trunk of the car were Ling Xingyu's two backpacks.

When Ling Xingyu saw the riverside walkway, he thought of hiding in the river. It's just that of course he can't jump down with these two bags. So, he put the bag in the trunk of the car in advance and waited for himself to climb up before getting it back.

Thankfully, they weren't discovered......

"Whew......" Ling Xingyu let out a sigh, and then carried two bags on his back and walked on the dark road.

Ling Xingyu relied on his memory as much as possible to take the original way, and then, he successfully returned the same way and returned to Shiguang Middle School.

On the side of Ichiko Middle School, the chaotic battle is over. The people who surrounded Ling Xingyu and them before, as well as the red armor, were no longer there. Only three corpses remained on the ground, as well as traces of the battle......

Ling Xingyu turned on the flashlight and walked to Luo Yan's corpse......

Ling Xingyu stood beside him, looking at Luo Yan, very sad and sad in his heart. He had only been in this world for two days, and he had encountered a lot of things. In this process, Ye Yao, Luo Yan, and Chen Tianxu were the only good people he had ever met.

And now, in front of himself, Luo Yan is like this......

"Luo Yan, thank you." However, there is only so much that Ling Xingyu can do........

After speaking, Ling Xingyu turned around and left, walking to the side of the battle traces on the street. On top of the fire marks and dust from the explosion were several small black or gray stones. Ling Xingyu picked them up one by one in a sealed bag again.

Then, Ling Xingyu walked into the school.......

The school was also dark and empty. Ling Xingyu turned off the flashlight and walked into the chemistry building. He went up to the third floor in the dark, and only turned on the flashlight when he reached the innermost experimental classroom.

This is just in case, in case someone is really still left at school, turning on their own flashlight, it's too obvious.

Entering the experimental classroom on the third floor, Ling Xingyu tried to turn on the light. As a result, as soon as he flicked the switch, the lights in the laboratory were turned on. Ling Xingyu was surprised, it turned out that not all circuit equipment needed to adjust the electrical box to open it.

After Ling Han turned on the lights, he walked over and closed the door and drew the curtains, so that the entire experimental classroom was in a closed situation. He then walked over to the lab table and placed two backpacks on the lab table.

Ling Xingyu opened Luo Yan's backpack, and from Luo Yan's bag, he took out the gray-white summoner that couldn't be used, as well as two energy sublimation seals that couldn't be used. Then, he took out several more sealed bags from his bag, all of which contained special stones and liquids that had fallen out of the Demon Angel's blown.

Ling Xingyu's current posture is completely like he is going to do an experiment.

However, he did have to experiment.

After Ling Xingyu took a deep breath, he looked down at these things on the experimental table and said, "Let's start........

After experiencing what happened at school in the morning, as well as what happened yesterday, Ling Xingyu had completely understood. In this world, if you want to survive, you must not only need materials, but also have strength.

Power, what does power refer to in the world?

Wisdom, weapons, armor.

These are all powerful!

And armor, without a doubt, is the most important strength. Ling Xingyu's clever head had sorted out all his thoughts when he was hiding in the water.

Luo Yan had told him that almost everyone had one of these gray-white armor summoners who had originally crossed into this world, but they couldn't use them. And Ling Xingyu felt strange, since it couldn't be used, why would everyone have one?

Although Ling Xingyu didn't know how they obtained these summoners, at least one thing was certain. These summoners must be useful, but the traversers don't know about it.

There were also the special materials dropped by these mad demons that exploded, and Ling Xingyu also felt very strange. These weapons can produce various elements and energies such as heat, electricity, and cold air, which is not in line with the physical and chemical knowledge that Ling Xingyu has learned.

Therefore, the experiment that Ling Xingyu has to do now is to study the armor summoner and these substances. He must find a way to be able to use the armor, otherwise let alone return to the original world, it will be questionable whether he can save his life in this world.

Ling Xingyu studied the armor first, and he placed the armor summoner on the instrument he was studying. Through the slight static electricity and heat energy, as well as the beating, Ling Xingyu wanted to confirm what kind of substance this summoner was made of.

After a moment, Ling Xingyu was puzzled: "It's harder than the alloy one." ”

Ling Xingyu tested the material through the instrument, and found that the summoner material was similar to mixed metal, that is, alloy. But his actual hardness is much higher than that of conventional alloys, and it is almost a military alloy, or even a higher level of material.

"The exterior material is weird, can this thing be taken apart?" Ling Xingyu said as he studied, wearing gloves and taking the summoner out of the instrument. Then he was subjected to external testing. It's just that he checked for a few minutes, and he couldn't find any place to open this summoner.

In desperation, Ling Xingyu could only conduct another experiment, the energy experiment.

Ling Xingyu placed the summoner on the experimental table and followed with the electrometer. Ling Xingyu wanted to see if there was any electricity in the summoner, that is, energy. Ling Xingyu was very curious, what kind of energy did the summoner use to summon the armor.

The test was quick, and as a result, there was no electrical energy.

Ling Xingyu then used other instruments to detect whether the summoner had other energy sources. As a result, the summoner has no heat or cold energy, and it doesn't seem to have chemical energy. Therefore, Ling Xingyu had already concluded that the summoner did not have any energy source.

There is no energy ........

In general, one instrument cannot be used, and there are two cases. The first is that there is no electricity, that is, there is no energy. And the second is broken, and the reason is very simple.

The material is harder than military alloys, and it is not easy to be damaged from the outside.

And the energy has not been detected through various tests, and from this point of view, the probability of the first is very high. The reason why the gray summoner can't be used is that it simply has no energy.

Ling Xingyu already had an idea.

He had to find a way to replenish the summoner and the sublimation seal.

"If you want to replenish energy, then try to see the electricity first, and try to see the summoner conduct electricity first." Ling Xingyu said, and began to operate as he spoke.

Ling Xingyu first used a conductive wire along with the electrical box and summoner, and then pressed the switch. But...... In just an instant, a large spark of electricity appeared from the surface of the summoner, and Ling Xingyu was startled and immediately turned off the electrical box.

"What's the situation?" Ling Xingyu said in a daze, and went up to test the summoner with the measuring electrometer.

The results of the electrometer showed that the summoner was out of power.......

In other words, just too strong an electric current did not lead to the summoner, and as a result, the electric current formed an electric spark outside the metal......

Ling Xingyu thought with his hands on his hips and said, "Strange, the current can't be conducted, why is this happening, does it mean that heat energy is used?" Or is it through chemical materials to stimulate the summoner? Eh, wait, chemical materials ......."

Thinking of chemical materials, Ling Xingyu suddenly remembered that the special substance that fell out of the mad demon envoy was exploded!

Thinking of this, Ling Xingyu immediately walked to the experimental table where the bags were placed and opened all the bags one by one. Then, with insulating gloves and tweezers, the special stones are taken out one by one and placed on the side of the magnifying glass and microscope.

"Since they are all born from the same world, there may be some connection between them, so let me try it." Ling Xingyu said with some emotion, and began to experiment with special materials as he spoke........
