Everything is ready, all that remains is installation. Of course, the first tap water of the Yaxin faction will be installed in the main building first, but this is not because Qiao Ya is the head of the house, but she is not sure if such tap water can be used, so she has to try it on her side first.

Installing water pipes is a trivial matter, but three times five divided by two, the hole of the whole building is laid, and the position of the water pipe is also very good.

The main water pipe is made of the thickest bamboo pipe, and the rest of the water pipes that flow to each room are thin bamboo pipes, Qiao Ya first went to the roof, built a super large water tower with the gold ability, and then put the water tower cover on it, and inserted the mana stone.

After a few seconds, the water tower began to rumble, and a large amount of water was poured into it, but after a while, the mana stone floated and the circle stopped working.

Joya opened the lid of the water tower and took a look, the water level inside had risen to the highest position, and it seemed that the first step had been successful. She immediately shouted downstairs, Poyang opened the water pipe on the first floor, and heard a gurgling sound from the water pipe, and then the gurgling water flowed out, the water became bigger and bigger, and finally the water became quite sufficient.

"There's water, there's water!" An Hongguang screamed in surprise, reached out and unscrewed the faucet and closed it several times, excited to no avail.

Qiao Ya asked Poyang to go to the rooms on the other floors and turn on the faucets a few times, and after a while, she heard the sound of water coming out of the water tower.

Succeed with flying colors! Even people like Joya, who are used to running water, can't help but touch three feet high. It's hard to live without running water, but the ability is so useful. If she had learned the contents of the Nameless Book earlier, maybe she wouldn't have lost to that person, right?

Teleported downstairs, and saw that Poyang and An Hongguang were still playing with the water pipe, Qiao Ya pretended to be calm and coughed dryly: "Ahem, have you played enough?" There are still a lot of water pipes to be installed, so let's go and install them first. ”

The rest of the things don't have to be done by Qiao Ya, only a big water tower needs to be installed in each yard, and the bamboo pipe connection is also a gold business, so it's all left to An Hongguang to do. As for the water tower cover. Qiao Ya has also made four of them a long time ago. That's enough for the four courtyards left.

Besides, the people in the West Courtyard are all dead now, and it's not a hurry to install a water tower or not.

"Teacher, what should I do?" Poyang only has water spells, but water supply doesn't need his water spells. He really wanted to do it, too. But there's nothing I can do to help. This made him a little distressed.

"You take a piece of space equipment and put the bamboo pipe on it for Xiaoguang to help." After Qiao Ya finished speaking, she turned around and walked upstairs: "I'll go to the laboratory to study it again." I've got to make a toilet to come out. ”

With the realization of tap water, Qiao Ya felt that maybe those convenience facilities in later generations could also be made by relying on abilities, so she decided to study them step by step, and in the future, not only these things could be used by the Yaxin faction herself, but also sold as a specialty of the Yaxin faction.

Anyway, others can't come out of the cottage if they want to, after all, no one can draw a magic circle except her, and only she can do mana stones, all the "supplies" and "patents" she is pinched to death, this business is sure to make money!

It's really not that she is in the eyes of money, but that the expenses of the Yaxin faction are getting bigger and bigger.

Before, the apprentices didn't know the ability, and the consumption was only daily necessities, but since the apprentices began to learn the ability, the demand for ability consumables has begun to increase.

Mana stones, magic weapons, these all need jade as a medium, and even if jade is again, it is dozens of times higher than the price of daily necessities.

Qiao Ya also planned to make more space equipment, at least let every apprentice in the sect who did not have space skills have one, but in this way, the demand for obsidian would be great.

Obsidian is rare, so the price has remained high. If you want to fully arm the sect, you can't just rely on robbery. Besides, there are not so many Xiao families in this world who can take advantage of Qiao Ya.

If you want to make a flush toilet, you have to make a sewer thing. To make a sewer, you need to dig a hole to build a large drainage channel.

These things were handed over to the craftsmen to study, so that they could hand over the drawings in the fastest time, and the rest of the work was Qiao Ya's alone.

Joya didn't know how to make porcelain, but she probably knew it was made of clay. So another item was added to the disciples' tasks, that is, to collect a certain amount of clay every day and bring it back to the sect.

There is a fire system, and firing is not a problem, but it can be fired successfully, and many experiments are needed. Joya finally succeeded in firing the first toilet bowl a week later, and then began to install the magic circle on the water tank. The circle on the toilet lid really didn't need to be very big, so in order to make the toilet easy to sell in the future, Joya tried to compress the circle to the size of a palm and set it in a ceramic lid with a spiral.

The ceramic lid inlaid with the magic circle, then screwed into the toilet lid, turned upside down to automatically dewater. As for the equipment in the water tank, it is the same as the installation in the water tower. As soon as the first toilet was made, Joya experimented with it several times. Of course, it was just a light flush, and the result was still very smooth.

And the drawings of the sewers, the craftsmen gave them early. Before Qiaoya's toilet was finished, Poyang had already dug the sewer with the students of the soil department. As for the water that is discharged, it is all extended down the mountain by a huge pipe, and this water is sewage but can be used to irrigate the fields. It just so happened that the land that Joya bought had already been cultivated, and the manure would not pollute the environment and could be used.

After the first toilet was filled, the rest of the time Qiao Ya only finished the magic circle, and the toilet was completed by the apprentices with the task. Since the toilet bowl requires both earth and water abilities, it can be regarded as the apprentices' cultivation and does not delay their progress.

In the following time, Qiao Ya made a refrigerator again, which was nothing more than adding a freezing circle, and using the knob to switch the size of the mana stone to adjust the temperature.

The invention of such a thing is not very useful in the sect, because most people have space props, and the things in the space will not deteriorate, and the refrigerator is just a cold thing to eat in summer.

So the refrigerator, on the contrary, became the first invention that Joya sold out.

It's the beginning of May, the weather is getting hotter, and people are changing into thin shirts. The refrigerator only used Qiao Ya to say a word, which immediately attracted the attention of many people, and the Qin family ordered four refrigerators at the earliest. (To be continued.) )
