Gu Li blinked unnaturally, as if she wanted to hide the panic in her heart.

As soon as she turned her head, she suddenly noticed the clue under her feet.

"What's going on with this place?" She asked, staring at the ground.

Around the hot spring pool, it looks as if it has been hollowed out.

"Is it empty?" She tapped her toes twice and asked again.

"Hmm." Yan Qing responded softly.

As he spoke, he suddenly crouched down and lifted up a stone slab that covered the ground.

Gu Li looked down and saw that what was placed under the stone slab turned out to be charcoal.

"What kind of design is this?" She was amazed.

Do you want to make a fire here? The hot spring room is already very hot, so if you burn the fire again, how hot will it be?

"There are tunnels around the pond that are filled with coal, and if you light it, you can heat the hot spring water, and boiling it is not a problem." Yan Qing explained.

Gu Li smiled helplessly: "What is it used for when it is heated?" Could it be that this water can still be used to drink? ”

Most of the hot spring water has sulfur and is not suitable for drinking, so what is he boiling it for?

Yan Qing smiled slightly and continued to explain to her: "As long as the doors and windows are closed, the steam generated by the boiling water can extinguish the miscellaneous bacteria in the air. ”

Hearing this again, Gu Li immediately restrained her smile and thought solemnly.

The hot spring water is hot, making it more convenient to operate. Moreover, the hot spring water has a certain bactericidal effect, and after boiling and transpiration, it stands to reason that it can indeed kill bacteria in the air. The sterile environment she wanted, she had it.

Gu Li suddenly realized that his intention was here.

"Feasible!" Gu Li looked at him and smiled, her clear eyes flashing with joy and excitement.

She now can't wait to give it a try and see if extracting penicillin in this environment will be successful.

"Then I'll start experimenting tomorrow." Gu Li said again.

"Don't worry, it's not too late to wait until the rain stops." Yan Qing said with a smile.

Gu Li nodded.

On rainy days, the temperature and humidity are unstable, which is really not conducive to experiments.

The problem that had plagued her for many days was finally solved, and Gu Li couldn't help but say to him; "Thank you."

If it weren't for him, she would definitely not have come up with this idea, and even if she did, she wouldn't have so much money to make it happen.

"Do you want to?" Yan Qing asked with a smile.

Gu Li understood what he meant, lowered his eyes and smiled, and nodded: "Yes." ”

I just said I don't want this house, but I haven't seen this hot spring laboratory yet. Besides, she left the lab aside, she really liked it here.

I have to admit that Yan Qing knows her very well, and everything she does goes straight into her heart.

It's so easy for someone like him to want anyone to like him.

The two of them left the courtyard, and the rain had not stopped.

"When will the rain stop?" Gu Li sighed, it has been going like this, when will her experiment start?

"Tomorrow." Yan Qing replied.

"How do you know? Are you watching the sky at night again? Gu Li asked with a smile.

"Nope." Yan Qing also smiled.

But if he said that he could stop tomorrow, he would definitely stop.

The carriage entered the city, and Yan Qing did not send her to the Spring Return Hall, but sent her home directly.

Gu Li enjoyed a half-day vacation with peace of mind.

The poison on the emperor's body has already been cleaned up, and since Gu Li rejected Gu Xianglan that day, she has never entered the palace to see her again, and Gu Zhilan has not looked for her.

A pair of sisters who had just been reunited broke up like this. The sudden sisterhood was also broken.

Gu Li was just a little embarrassed in her heart, and she didn't feel how sad she was.

She and Gu Zhilan are really not familiar with each other, and besides, she will not harm others because of her.

It's good to act as if you've never seen her, that those things never happened.

The next morning, Gu Li pushed open the door and saw that the outside was as Yan Qing said, the rain stopped, the wind stopped, and the bright morning sun fell warmly on the ground.

The air was mixed with the fragrance of plants and trees after the rain, Gu Li took a deep breath and felt relaxed and happy.

She was in a good mood and went to the Spring Return Hall early after breakfast.

In the laboratory of the Spring Return Hall, there are still the remaining things from her previous experiments, and she plans to move them all to the newly built hot spring laboratory.

After a spring rain and a warm day, the early summer quietly came, and the air began to be a little hot.

Gu Li's experiment had already begun, and she went to the orchard she had been to last year, looking for a lot of rotten green plums in the garden, and began to cultivate them in a petri dish.

Staphylococci have also begun to grow, but these take time and are not cultivated in a day or two.

Gu Li was full of expectations, however, the sky was not beautiful, and it rained again.

This time the rain was heavy and pouring, and it rained for two days and two nights before it stopped.

The rain was heavy and the time was long, and it was not surprising that there was water in Changning City. The place where Gu Li lives belongs to a civilian residential area, the terrain is relatively low-lying, and the water in the house is serious, and when the water is at its deepest, it is about to reach the knees.

There was also water in the room, and the whole house was extremely damp.

Jin Zhi took a bucket to clean up the stagnant water in the yard, but so much water could not be cleaned up in one or two clicks.

"Fortunately, it's summer now, and the weather is not cold, but if it's winter, it's really unliveable." Jin Zhi complained as he cleaned up.

Gu Li was not optimistic at all, it was because the weather was hot now, so it was more dangerous.

The weather is hot, all kinds of bacteria are also active, and things that have been blistered are easy to rot, so it is easy to develop some diseases.

Gu Li was thinking of ways to prevent problems before they happened, when she suddenly heard a voice calling her from the door.

"Miss Gu, is there serious water accumulation in the house?"

It was Wu Bai's voice.

Gu Li lifted the hem of her skirt and walked out in the water.

"It's okay, it's being cleaned up." Gu Li replied and asked, "Has your house also been flooded?" ”

Wu Bai shook his head with a smile: "That's not true." ”

The house where Yan Qing lives has been renovated, the ground is high, and the drainage is very good, so there is no water in the house.

Gu Li thought that Wu Bai was coming to help them clean up the stagnant water, but unexpectedly, she heard him say: "Miss Gu, I can't live here, Gongzi asked me to pick you up and Miss Jinzhi." ”

Gu Li was suddenly surprised, and even Jin Zhi, who was cleaning up the stagnant water in the courtyard, stopped his movements in surprise.

"Let's go? Where to? Gu Li asked.

She knew that Yan Qing had not been in Changning recently and had gone to Jian'an, so where did he want Wu Bai to take them?

Wu Bai replied with a smile: "Gongzi still has a mansion in Yongping Lane, let me take the two girls there." ”。

Gu Li knew that Yongping Lane, which was a residential area for dignitaries, was expensive and high, even if it rained heavily, there would definitely be no trouble with stagnant water.
