Time passed quickly, and in a blink of an eye, it entered the summer, although the weather was not too hot, but Bai Yunyi, a person who was afraid of heat, left the emperor and went to Zhuangzi on the outskirts of Beijing to escape the heat.

She dared to swear that she was definitely not doing this to avoid the emperor, first, there was no need to avoid her at all, and secondly, the emperor's martial arts were strong, and it only took two quarters of an hour to travel between the palace and Zhuangzi in the capital, which would not be difficult for him at all.

Mainly because this place is really comfortable to live in, the mountains and rivers are beautiful, cool and comfortable, who wants to go to the capital to get heated.

The most important thing is to live in Zhuangzi and be quiet.

In addition to following the emperor to the imperial forbidden land to practice early in the morning, she can comfortably do what she wants to do after she comes back.

Like what...... Last year, the emperor recruited more than a dozen extremely intelligent people for her, and Bai Yun accepted them as apprentices, and since last year, he has taught them a lot of physics and chemistry from the earth.

Now, the thermite she wanted, the locust killer, the black powder, and so on, were all made by these people.

Since learning of the existence of the Nine Domains Abyss and the existence of aliens, Bai Yunyi has started a secret plan.

After lunch, Bai Yunyi went straight to the special large courtyard behind Zhuangzi.

Now, this large courtyard has become Bai Yunyi's secret laboratory, and it has been in use for three months.

Of course, the real place for experiments is in the underground secret room, or in an uninhabited place.

In addition to this, she also has a large laboratory in the county lord's mansion, which has always been managed by Moon Ice and Moon Frost.

Although these two girls are not very talented in learning the knowledge she teaches, they at least manage the two places in an orderly manner.

"Miss." When Yuebing and Yueshuang saw Bai Yun coming, they hurriedly greeted them and bowed on their knees.

"How's it going?" Bai Yunyi asked with a smile as she walked inside.

"Miss Qiyu, most of the things you want have been made, and there are about three days to go, and you can prepare them all." Yue Bing hurriedly said.

"No one was poisoned, was it?" Bai Yunyi hurriedly asked.

"No, no, don't worry, Miss, they are all extremely smart people, and they have been making the gas canisters you want according to the method taught by Miss, and they don't dare to mess around, so everyone is alive and well." Yueshuang hurriedly said.

Just kidding, the young lady used a little bit of that venom to test, and poisoned a large piece of fish, and everyone felt creepy after watching it, of course, they didn't dare to joke with their own lives.

"That's good." Bai Yun breathed a sigh of relief after hearing this.

Those dozen people are her pillars, not only extremely smart, but also inferences.

Bai Yunyi was afraid that they would be too good at "drawing inferences", and they wanted to innovate too much, so they put their own lives into it.

It turns out that smart people still spare their lives.

"By the way, Miss, Wu Dao improved the rocket launcher made by Miss yesterday, and the power is amazing." Yue Bing said with a smile.

Wu Dao is the most talented one in this group, especially has a natural fanaticism for making weapons with black powder, and he has been immersed in research all day long, and has now caught up with Bai Yunyi.

To be honest, Bai Yun knows some theoretical things, and it is not so easy to put them into practice, and it is even more difficult to completely turn them into weapons, but these people can do it slowly.
