Chapter 552 Various flatbreads prepared in advance

Others were quickly attracted by the water tank and joined in the observation.

Finally, it was discovered that the water in the water tank seemed to be introduced through pipes.

The water level in the water tank seems to be related to the water polo floating on the water.

The more these old men studied, the more amazed they became.

Anyone who can come up with such a device is simply a genius.

Even if they were given decades of time to build such an exquisite device, they might not be able to build it.

Unexpectedly, the appearance of Donglan College looks ordinary, but the things inside are full of mystery.

"Patriarch, did Miss Lu's last letter say that we should be the masters of Donglan College?" the second elder suddenly asked.

The leader of the Mo clan nodded, "Not bad."

"Hahaha, doesn't that mean that I can use this hut every day in the future?" The second elder looked surprised, then looked at the elder who was studying the water level device seriously, and snorted coldly, "Elder, I

I remember you said on the way here that you would return to your ancestral home as soon as you get the answers to the exercises, and I hope you will not go back on your promise then."

The great elder's expression immediately changed, and he said in an unnatural tone, "It's just some small tricks."

Don't try to trick him into staying with something like this.

"Look at the sink here." Another elder began to exclaim.

When they entered the door just now, everyone was attracted by the mirror and did not notice the sink under the mirror.

There are two devices equipped with valves on this sink.

After unscrewing the valve, water flowed out.

There was also a box of soap that they had seen at Miss Lu's last time on the table. It was obviously placed here for people to clean their hands after going to the latrine.

After washing your hands, tighten the valve again.

The water in the pipe was shut off.

The sewage flows directly to other places along the pipes below.

There is no need to fetch water and pour water by yourself like before.

This kind of device really saves time and effort, is convenient and considerate!

The elders of the Mo family stayed in the bathroom for a long time, and finally came out reluctantly.

In the square outside in the distance.

Lu Yunluo was bored waiting and was looking at a stone tablet she had specially ordered some time ago.

The shape of this stone tablet is irregular, and its color is either black or gray. It really has no sense of beauty at all.

On the other hand, the four vigorous and powerful characters "Learning is boundless" look pretty good.

"Mother, did these elders fall into the latrine? Should we find someone to go in and take a look?" Yin Shuang glanced at the direction of the public toilet with a worried look. After all, these elders were fooled by the mother for a long time.

He came to the capital on a scam. If something goes wrong, the empress will suffer heavy losses.

Lu Yunluo smiled and said, "Just wait a little longer."

She also installed a flushing device in the toilet. If those old men don't study it, they might not come out.

I hope they don't tear down the toilet.

Sure enough, they waited for a long time before the old men slowly came out of the public toilet.

The old men were still amazed when they came out.

The look she looked at Lu Yunluo gradually turned to respect.

The Mo clan and Miss Lu are definitely the wisest choices.

"Have you finished your research?" Lu Yunluo looked at them with a smile.

The leader of the Mo clan was a little embarrassed, feeling like an ignorant country bumpkin, "I kept Miss Lu waiting for a long time."

Lu Yunluo turned around and said, "It's okay. Let's go. I'll show you the library of Donglan College."

In this library, she has more than just answers to exercises.
