Ling Xingyu began to try to use static electricity to stimulate the characteristics of the red stone. He used an electrostatic generator, and it worked. The cells on the surface of the stone are very active, and the essence of the stone is not depleted.

So, Ling Xingyu used some chemicals that were easy to rub and produce static electricity, such as PTFE and silica, and put them together in the test chamber.

Then, Ling Xingyu put a few red stones and the gray-white energyless sublimation seal into the test chamber. Then, Ling Xingyu connected the wires in the test chamber, connecting the stone with the sublimation seal, as well as many chemicals.

Close the chamber and connect the wires. Then, Ling Xingyu took two steps back and pulled down the electric switch!

"Buzz!" There was an instant sound in the test chamber, and the display light of the box immediately lit up. But within a few seconds, the surface of the test chamber suddenly appeared with an electric spark, and Ling Xingyu and Ye Yao hurriedly took a few steps back.

"What are you doing here!?" Ye Yao asked in surprise, looking at Ling Xingyu. Experiments, that's too much of an exaggeration! What is this for?

And Ling Xingyu on the side also blocked the front with his hand, looked at Ye Yao and replied: "I'm introducing the components of the stone and chemicals into the sublimation seal, because the conventional current can destroy the stone components, so I'm using a strong current to do instant excitation!" ”

"Bang bang bang!" The electric sparks are non-stop!

After waiting for about ten seconds, Ling Xingyu went to the side and pulled down the main power switch. The current and electric sparks in the test chamber stopped, and the lights and instruments in the entire laboratory room also stopped. Ling Xingyu breathed a sigh of relief and said, "Whew..... It's a scary scene, but hopefully the experiment will be a success. ”

With that, Ling Xingyu stepped forward and opened the test chamber, and a pungent white smoke suddenly came out of the test chamber. Ling Xingyu hurriedly covered his mouth and nose, and waved the cigarette in front of him with his hand and retreated.

After taking a few steps back, Ling Xingyu coughed a few times before looking ahead. The smoke in front of him was dissipating at this time, and after it had almost dissipated, Ling Xingyu stepped forward again and quickly took out the sublimation seal in the test chamber.

The energy sublimation seal that was taken out was also smoking, and Ling Xingyu quickly patted it with his hand wearing insulating gloves. After extinguishing all the smoke, Ling Xingyu could finally see what the Sublimation Seal looked like now.

Now the energy sublimation seal, the color has changed. From off-white to solid red!

Ling Xingyu succeeded!

"Hahaha, it's a success, the experiment is successful!" Ling Xingyu said with an excited smile.

"Did it work!?" Ye Yao also stepped forward in surprise and said, looking at the energy sublimation seal in Ling Xingyu's hand. And Ling Xingyu also immediately handed the Energy Sublimation Seal to Ye Yao, Ye Yao took it and looked at it carefully, and saw the change in the color of the Sublimation Seal very clearly.

"Let me try the real one!" Ling Xingyu said, and after speaking, Ye Yao stretched out his hand. Ye Yao placed the Energy Sublimation Seal in Ling Xingyu's hand, and Ling Xingyu immediately picked up the Sublimation Summoner from the experimental table and inserted the pure red Energy Sublimation Seal directly into another slot at the top of the summoner.

Suddenly, a flash of light flashed from the transparent trigger button at the top of the summoner. This means that sublimation is imprinted with energy!

"yes, the experiment was successful, my theory is not wrong!" Ling Xingyu excitedly raised the summoner in his hand and shouted.

"Is that what it means to upgrade?" Ye Yao stepped forward and asked with a smile. Ling Xingyu put down the summoner, turned his head to look at Ye Yao and nodded: "Well, it should be, I think, the two slots on the summoner should mean this." ”

And at this time......

"Buzz, buzz........" Ye Yao's mobile phone rang.

Ye Yao took out his mobile phone, connected it, and then said, "Hey, hello, that one?" ”

"Is it Ye Yao? I'm Ah Lu, are you and Ling Xingyu still in school? On the other end of the phone, Ah Lu asked.

"Yes, yes." Ye Yao said.

"Okay, you'll be back right away, the people in the team who used to scout the subway station are back, and we're ready to act right away." Alu said.

"Okay, I'll be back with Xingyu right away." Ye Yao said, after speaking, he hung up the phone. Then turning his head to look at Ling Xingyu, Ye Yao said, "Ah Lu said that the people who went to scout the subway station over there have come back and asked us to go back and prepare for action." ”

"Then go back, it's important to save people." Ling Xingyu said.

"Hmm." Ye Yao said.

So, the two went back.....

After going back, the team of more than 20 people gathered in the central square of the ancient temple. Han Gang, on the other hand, stood on the stone steps of the Dacheng Hall and said to the people below: "Everyone, Xiao Luo and Ah He have returned, and we have confirmed that there are other passages in the subway station to enter." And yesterday, we also had a new member with armor. Now, it's time for us to rescue our comrades! ”

After a few moments, several people below responded.

"That's right!"

"We must save everyone!"

"I've wanted to look good at those bastards for a long time!"

........

"All combatants, go!" With Han Gang's shout, several people in the crowd lined up, and they were all selected in advance. Once the battle to recapture their comrades begins, they are combatants.

It's just that their weapons are a bit shabby, most of them are knives, hoes, clubs, and clubs, and there are only two hot weapons. However, Fan Yun, who was at the forefront, dressed in white, was holding an armor summoner in his hand.

Ling Xingyu looked at Ye Yao beside him and asked, "If you want to, don't go together, you don't have any weapons." ”

Ye Yao shook his head and said, "No, I'll go with me, I don't want to hide in the rear." ”

"But ...... you," Ling Xingyu asked suspiciously.

"Don't persuade me." Ye Yao decisively interrupted Ling Xingyu.

"......." Ling Xingyu was speechless for a moment.

Although they haven't known each other for a long time, Ling Xingyu already knows Ye Yao quite well. The girl's mood did not change much, she often spoke and acted lukewarmly, and did not feel cold and enthusiastic. However, once she decides what she wants to do, she will not change it easily.

Therefore, Ling Xingyu had no way to say any more.

So, counting Ling Xingyu and Ye Yao, a combat team of ten people left from the ancient temple. And everyone in the ancient temple also packed their luggage and left at this time.

This was planned by Han Gang and the others in advance, and when the battle began, the rest of the people took their luggage and took refuge in the designated positions that only Han Gang or Fan Yun knew. If the battle goes well, they will go to various locations to inform them and come back with supplies to assemble.

If there is no response after more than 72 hours of fighting, it means that the operation has been lost, and they will leave with their own supplies.

The combat team walked on the street, Han Gang walked in the front, Fan Yun followed, and Ling Xingyu and Ye Yao walked in the middle of the team. The team is heading to the captured metro stronghold, ready to reclaim their companions and supplies!
