Wu Zetian, Shangguan Wan'er heard the sound and hurriedly walked out of the room to the residence where Jiang Yichu was.

"Xianren, has the engine been developed?" Wu Zetian asked from the door.

Shangguan Wan'er did not speak, but there was also a feeling of expectation in her eyes.

"The research is done, the research is done." Jiang Yichu opened the door and said after looking at the two of them.

"Where? Can you tell me to have a look?" Wu Zetian was already very curious about the engine, and now he heard it, he couldn't help asking immediately.

"This is it." Jiang Yichu took out the engine.

It is a spiral-shaped thing, about three feet long, very tall, and looks very advanced.

"This is the engine? Doesn't it seem to be anything special?" Wu Zetian observed two eyes and frowned.

"It feels very ordinary." Shangguan Wan'er was also puzzled.

"Really? Now I'll tell you to look at the magic of the engine." Jiang Yichu said mysteriously and was about to press the switch.

At this time, Li Lingyue also opened the door and walked out without interruption, watching quietly from a distance.

Jiang Yichu chuckled and pressed the engine.

boom.

The roar sounded, the gears in the engine began to spin quickly, and the air was clearly felt.

"Well, the performance of this engine is too powerful?" Wu Zetian said in surprise.

"So this is why the fairy praises the engine?" Shangguan Wan'er nodded and said.

"No wonder, it's too simple to have this thing away from this desert island." Li Lingyue also said.

"Fortunately, this is just one of the most common engines I studied." Jiang Yichu shook his head, looking very humble.

"Fairy, let's hurry up and install this engine on the ship?" Wu Zetian said in silence.

"Yes, immortal, it should not be too late, install it earlier, and get it done earlier." Shangguan Wan'er also said.

"Okay, then." Jiang Yichu nodded, and took the engine to the side of the ship.

At this time, the shape of the ship has been built, tens of meters or so, it looks very majestic.

"Fairy, where should this engine be installed?" Wu Zetian looked up and down and asked strangely.

"It must be installed inside, otherwise where do you think it is installed?" Jiang Yichu glanced at Wu Zetian, rolled his eyes and said.

"Inside? But now that the ship has been built, is it necessary to forcibly demolish it?" Shangguan Wan'er asked Jiang Yichu.

"It's not necessary. I have already left a corresponding hole under the ship." Jiang Yichu said mysteriously, leading the three to come under the ship.

There, there was a hole like a square.

"Is this the hole where the engine is installed?" Wu Zetian glanced twice and nodded.

"Yes, wait for me here for a while." Jiang Yichu said, walking towards the entrance of the cave.

"His Royal Highness, shall we follow?" Shangguan Wan'er said after taking a look.

"Follow up? Why do you follow up? See if the fairy installs the engine? We won't." Wu Zetian looked at the superior Wan'er and reprimanded.

"All right then." Shangguan Wan'er was very aggrieved and stopped talking.

"Wan'er, what your Highness said is reasonable, and we are only causing trouble to the fairy." Li Lingyue said after taking a look at Shangguan Wan'er.

"Yeah." Shangguan Wan'er nodded, not talking.

Time passed quickly, and after a short while, Jiang Yichu came out of the cave, and his clean clothes became messy.

"Xianren, how's it going, is the engine installed?" Wu Zetian asked after a glance.

"It was installed, but I didn't expect how long it took to clean up, and the inside was already so messy." Jiang Yichu glanced at his messy clothes and smiled bitterly.

"The inside is already so dirty, I guess the outside is even dirty." Li Lingyue said after taking a look.

"Should we go to clean it?" Shangguan Wan'er said with a rolling eyeball.

"Okay, let the fairy go and change clothes, this ship will be handed over to me and Wan'er." Wu Zetian looked at Jiang Yichu and said.

Jiang Yichu was not stubborn, nodded, and walked towards his house.

When he came to the house, he took off his dirty clothes and took out the new clothes he had prepared before.

Although he had only one piece of clothing before coming to the desert island, he had already made one to prevent rain or something.

After putting on new clothes, Jiang Yichu felt much better. He looked at the dirty clothes on the ground and frowned: "There is no washing machine on the desert island. It is really troublesome to wash clothes by hand."

"However, no matter how difficult it is, we must wash it."

Jiang Yichu sighed, took the clothes and put them in the basin, and poured water.

After rubbing it twice, he suddenly felt something wrong: "Hey, I forgot all about it. There is no washing powder."

Having said that, Jiang Yichu came to the warehouse and started making washing powder.

He had seen the method of making washing powder before and remembered what conditioning was used to make it. It was very simple.

"Yes, bleaching powder, soaking bleaching powder in water can make washing powder." Jiang Yichu said and took out a large bag of bleaching powder.

Rushing.

The bleaching powder fell into the water and floated, splashing out a series of splashes, which looked amazing.

Jiang Yichu glanced twice and started to stir, and the washing powder was made in a while.

After a slight sniff, I found that the washing powder still had an unspeakable fragrance.

"It's weird, but my washing powder is finally ready to wash clothes." Jiang Yichu said, and began to pour the prepared washing powder on the clothes.

The clothes that were originally dirty began to become smooth and tidy under the action of washing powder.

Jiang Yichu's eyes lit up and he began to rub it hard.

Within a few minutes, the dirty clothes had been cleaned.

Jiang Yichu easily put it on the clothes hanger and walked towards the ship.

"Xianren, have you changed your clothes?" Shangguan Wan'er's voice sounded before she got closer, looking at Jiang Yichu and said.

"Yes, how are you cleaning up the ship?" Jiang Yichu nodded and said to the ship.

"It's almost done cleaning up, immortal, take a look." Wu Zetian said with a chuckle.

Li Lingyue was beside her with a smile.

Jiang Yichu nodded, got on the ship and started checking.

I don't know it, but I was shocked.

The wooden planks on the ship were clean, tidy, smooth, and completely different from the dirty ones before.

If he hadn't seen a ship before, he thought he was on the wrong ship.

"You cleaned up these?" Jiang Yichu opened his eyes wide and said to Wu Zetian.

"Yes, why? Are you dissatisfied with the cleanup!" Wu Zetian said when he saw Jiang Yichu's expression.
