The weather was a little cooler, with a light mist under the night sky and the moonlight becoming hazy.

The street lamps on the streets of Liyue Harbor were lit up, as were the lanterns in front of the merchants, emitting a bright yellow glow to dispel the darkness that followed the night.

Li Qiuzhi looked up at the street lamps, which may have been lit with kerosene, or animal and vegetable oils.

After thinking about it, he asked Keqing:

"Does Teyvat have a metal that glows when it comes into contact with the elemental thunder? If there is, it can replace an open flame to make a safer and brighter electric light. ”

He briefly explained the principle of electric light and Keqing.

When Li Qiuzhi was in school, he heard the teacher talk about the principle of electric light, which was realized by using carbonized bamboo wire to electrify in a vacuum glass bottle when the electric light with practical effect first came out in the 19th century.

At the beginning of the twentieth century, carbon filaments were replaced by tungsten filaments with higher melting points and better luminous efficiency.

Teyvat has gold, silver, copper and iron, and I think that tungsten also exists, but I don't know if the name is also "tungsten".

Maybe there are better metals than tungsten, after all, there are elemental forces in this world, so it shouldn't be too difficult to reproduce electric lights.

"Tungsten? There is indeed this metal, but I don't know if it's the same one you said. Keqing pressed against her fair chin and pondered for a moment:

"According to your description, the electric lamp is indeed much better than the current oil lamp, well, I will have the Ministry of Industry and Construction to forge a tungsten wire tomorrow and try it.

"If you are sure that there is no problem, tell Ningguang and ask her chamber of commerce to arrange the production of electric lights, and then I will arrange a pilot area as soon as possible to confirm that there are no problems and then we can promote it in Liyue."

With another world as a reference, Keqing has no doubts about the correctness of developing electric lights.

"Well, it's worthy of Lord Yuhengxing, so quickly I have a specific idea." Li Qiuzhi pretended to be flattering, and then smiled and secretly hugged her waist.

"Bastard, I'm back!" Keqing's fair face showed a hint of crimson, but it was not very noticeable in the night.

When no one is around, it's up to you, so she won't let Li Qiu succeed on the street!

"It's all at this time, why don't you go to dinner with me?" Li Qiuzhi tried to find a reason to stay.

"Hmph, I still have to go to the General Affairs Department before everyone gets off work to arrange tomorrow's construction and prepare for construction, let's talk about it next time!"

Keqing refused mercilessly.

"Okay." Li Qiuzhi showed regret on his face, he always didn't want to disturb her work, so he had no choice but to make an appointment to eat together when he was free.

The two walked to the General Affairs Division, Keqing said goodbye to Li Qiuzhi, and he also returned to the fairyland space.

At this time, everyone basically came back from work, today it was Ying, Yun Jin and Mona cooking dinner, and the others should have gone to the hot spring bathhouse to take a bath.

In the living room, Eula and Amber were chatting, Shenhe was also sitting on the sofa meditating and resting, and the ice-white spirit was sweeping the floor with a broom.

Li Qiuzhi walked up to the girls and sat down.

As if she was a little tired after a day of work, she lay down next to Eula, put her right hand on her lower abdomen, and gently stroked the semi-translucent black silk that was clinging to her snow-white skin.

Eula grabbed Li Qiu's moving hand, looked at him and asked:

"Where has the incarnation of Lingna been in the beast realm lately, have you found any dangerous places?

"There are already enough Favonius knights over there at the base, and the plan to clear out the monsters in the Beast Realm has been implemented for a while, but only some scattered monsters have been encountered."

With a healing ointment that specializes in the bleeding effect of beast realm monsters, the Knights of Favonius are basically invincible when they encounter beast realm monsters.

Li Qiuzhi withdrew his right hand, untied the black leather belt under Eula's chest that bound the short white coat, and replied while putting it aside:

"With the Demon Bear Territory as the center, I have explored within a range of 1,500 kilometers around, and the monster groups I found have also been cleaned up, so there should be no danger."

With Li Qiuzhi cleaning up the monsters, the knights only need to clean up the lone monsters on the side of the beast realm, and the pressure is much less.

With that, he was about to take off Eula's waist-length white lace coat, when she suddenly folded her arms under her chest instead of a sash to restrain her.

A slight flush appeared on Eula's fair face, and she "snorted" dissatisfiedly, and continued to get down to business:

"Geologists of the Order have been to the Beast Realm to study it, and they say that with the kind of 'fertilizer' that has been researched by sugar, it can be used as an agricultural production base in the Beast Realm.

"It's just that most of the wasteland over there has less water, so you need to make artificial rain to change the environment there."

Li Qiuzhi nodded, probably understanding what it meant, he couldn't break through Eula, who was strictly guarded.

I had to put my hands on the plump thighs that were exposed between her over-the-knee boots and leather bodysuits, and gently kneaded her snow-white skin:

"Are you saying let me go to the Beast Realm and use the water element to transform the environment?"

The Beast Realm is different from the general secret realm, it has sunlight and land, and it is also very large, so it is really good to use it as an agricultural production base without the threat of monsters.

The Beast Realm monster cleanup plan formulated by the Knights at the beginning, most of the threatening targets had already been almost completed by Li Qiuzhi himself.

The rest of the Knights of Favonius can do it by themselves and the adventurers who come to explore.

In addition, the Knights of Favonius have thought about it, and the base is also very good, and the scale is about the same as that of the town.

Therefore, I also had the idea of developing and utilizing the beast realm, and agriculture was a better choice that the Knights had discussed.

"It's a lot of work to renovate the environment, even you should find it troublesome, you just have to go over there and make a few holes in the ground and fill it with water."

Eula slid her right leg onto her left leg and clamped Li Qiuzhi's hand between the inside of his legs, and he couldn't move.

Amber couldn't help but smile beside him, and Shenhe also looked at him quietly.

Feeling the warm body temperature transmitted by Eula's plump thighs completely wrapped his hands, Li Qiuzhi's various attempts were unsuccessful, so he had no choice but to finish chatting first:

"Okay, it's not difficult, I'll go to the Beast Realm with you tomorrow to finish the matter of the reservoir."

"When you're done, Jean will pay you." Seeing that Li Qiuzhi agreed, Eula put down her leg and let go of his hand and said.

Although it is to let his own man do things, the remuneration he deserves is still indispensable.

"It's just free."

Li Qiuzhi didn't care about this, after all, he didn't go to help much, this time he hugged Eula and picked her up and sat on top of him.

Then he put his hand on her waist and slid his palm under her arms and short coat, and gently pushed it out, this time with only a symbolic resistance, and then lowered her hands.

It's too late for the second chapter, so I'll change it tomorrow.

Ask for a monthly pass, ask for a recommendation, ask for a follow-up, thank you for your support!
