With He He's help, they used the stars to quickly go down from the well in the compartment to the cave below. Pen, fun, pavilion www. biquge。 info

In the middle of the huge cave, there are several people rummaging through the ruins. Pieces of broken bricks tumbled down, kicking up small clouds of dust and smoke.

Faced with such a large ruin, those few people had a bit of a hard time finding it.

Zhu Ziye, who was strong, couldn't stand it anymore when he had been bending over, and picked up a waste brick and complained, "Eighth brother, we have all looked for this ruin, and your bag can't be here."

"No, I remember that I went down the cave with my bag at the time, and then I left the bag here because of an accident, and then you just helped me find the black suit, so the bag should still be in this ruin" Ye Cheng said with a solemn face. Faced with such a heavy weight of masonry pressing down, he was worried that the contents of his bag would break.

Ye Cheng worked hard to rummage through the ruins, his thin body and the injury on his chest were not completely healed, doing the physical work of turning bricks and digging mud, which made him a little unbearable, and cold sweat gradually broke out on his face. Coupled with the fact that the oxygen in the cave was a little thin, his breathing gradually began to become a little rapid.

With his hands in the rubble, he stopped looking, and sat weakly on the bricks.

After Bai Yingping, who was not far away, found it, he walked over slowly, and said with some gasp, "I've been looking for so long, and now there is only a little place left." Your injuries are not healed yet, so you should rest for a while."

"Don't talk about me, you are the same, look at you now, you are panting when you speak" Ye Cheng choked back.

Bai Yingping laughed and sat on a broken brick.

"I think you two are seriously injured and you need to rest" At this time, Zhu Ziju stepped on the ruins, patted off the dust on his hands, and raised a small cloud of dust and smoke around his hands.

"Brother Ziju, did you find it?" Ye Cheng looked at the Zhuziju who came from the side and asked.

"Not yet, but the eighth brother confirms that the bag is here, I think I will find it" Zhuzi Juju sat down on the side of Ye Cheng, and said with a solemn face, "While Brother Bai is also here, I want to ask you, if it is really as Yan Hou said, there are other countries that want to attack the Tiangu Kingdom, then what should we do?" ”

These words made the atmosphere a little solemn.

After Bai Yingping thought for a while, he raised his head and looked at Ye Cheng opposite.

When Ye Cheng found out, he asked with some surprise, "What do you mean by looking at me like this?" ”

"Of course, I asked what you want to do, now that Cao Rou has returned to the imperial court, I believe there will be news soon. Now that you've found another phone, are you going to find a way home, or are you going to continue to help Cao Rou solve the affairs of the Tiangu Kingdom? Bai Yingping asked.

Ye Cheng took out his mobile phone, held it in his right hand, and stared. This mobile phone has a combination lock, which is not available to him at all, but the call that came makes him very concerned.

But now that the phone is out of battery, if you can't find the charger in the bag, you can't charge the phone in the original way, and you can't answer the call at all.

So he pinned all his hopes on that bag.

Putting away the phone, Ye Cheng raised his head and said, "Let's stay in the Tiangu Kingdom first, let's talk about it, wait for the phone to be charged, answer the phone, and think about the next step." ”

"Now it seems that this can only be the case," Zhu Ziju said helplessly.

After resting quietly for a while, the three of them were ready to get up and continue looking.

At this time, on the edge of the ruins, Zhu Ziye happily raised his hands and shouted, "Eighth brother, look, I've found it!" Got it!! ”

Ye Cheng hurriedly heard the sound and looked over, and saw that Zhu Ziju's raised hands were holding his white slanted shoulder bag.

Zhu Ziye quickly ran over and handed the slanted shoulder bag to Ye Cheng.

Taking the slanted shoulder bag, I saw that Zhu Ziye's hands were covered with mud, and his face was full of dust that he hadn't had time to wipe off. Ye Cheng hurriedly thanked him, "Thank you, Brother Ziye"

Zhu Ziye looked stupid, clapped his hands, scared the dust off, and said, "It's nothing. Suddenly, he calmed down and continued, "By the way, Eighth Brother, this bag is buried in the mud and sand, there is nothing hard around, you can see if the things in it are broken."

The white slanted shoulder bag has been eroded by the dust and has turned muddy yellow. Ye Cheng touched the bag and found that it was still bulging, and his heart was happy. He quickly unzipped it and rummaged through the contents with his hands.

Soon he felt the data cable and charging head, and he quickly took them out and checked them. Seeing that the white data cable was not damaged at all, the two connectors were not dusty, and the square charging head was not damaged, he quickly put it back in the shoulder bag and continued to touch it.

Touching the cold metal block, he took out the bag and looked at it, and after confirming that it was zinc and copper, he said with a smile, "Great, intact"

"Great, then hurry up and go back and charge your phone as before," Zhu Ziye said happily.

"Hmm," Ye Cheng nodded.

Using Xingchen to quickly return to the dormitory, Ye Cheng poured the contents of the shoulder bag on the round table in the room, and the data cables, charging heads, zinc blocks, copper blocks, and some unused salt were scattered on the round table.

He He had never seen Ye Cheng charge his mobile phone with such a thing, so he asked with some curiosity, "How can I use these things?" ”

Zhu Ziye said a little proudly, "Just look at it, the eighth brother will soon make the phone light up"

He He was still a little puzzled, staring at the things on the round table.

At this time, Zhu Ziping's shout came from the door, "Eighth brother, what you want is here" He slowly ran to the round table with a large round wooden barrel in his hand and put the wooden barrel down.

The large round barrel is relatively large, and it requires Zhu Ziping to open his hands to hold it. The bucket was only a dozen centimeters high, and it was filled with water, and there were some transparent crystals in the water.

"Eighth brother, according to your orders, I have already put a lot of salt down," Zhu Ziping said.

Ye Cheng saw the crystals precipitated in the water and knew that Zhu Ziping was not lying. And in the process of escaping, they have also seen how he makes galvanic batteries, so they know how much salt to add.

"Thank you, Brother Ziping," Ye Cheng thanked.

He then stood in the middle of the barrel in the shape of a cube of zinc and copper, with a quarter of it still protruding from the water. Then take a long wooden block and fix it. Connect the data cable and the charging head together, plug the data cable into the charging hole of the mobile phone, and then touch the metal block on the charging head to the zinc block and copper block.

After standing still for a while, the galvanic battery slowly undergoes a chemical reaction, and the generated electricity is transmitted to the mobile phone little by little.

The phone screen starts to light up, and a battery pattern appears in the center of the screen, and the power level moves around in a grid, indicating that the phone can be charged normally.

Seeing this magical scene, He He exclaimed, "What's going on?" ”

"Haha, it's amazing, it's the first time we saw it." Zhu Ziye said proudly again.

Ye Cheng was so surprised to see He He and wanted to explain, but for an ancient person, it was impossible to understand. He tried to explain to Zhu Ziju and others, and after saying a lot of knowledge, they were even more confused.

Then it's better not to explain.

"Actually......"

As soon as Ye Cheng wanted to speak, he saw Xiao An walking into the room.
