In Nie Jingchuan's opinion, these requirements are nothing at all, if they can burst into flames out of thin air, it is a very unexpected thing to treat the enemy, and this surprise in many battles is often a winning trick.

In addition, if you have to send someone to secretly burn the enemy's grain and grass on the battlefield, the speed of flint and steel is too slow and it is likely to be discovered by the enemy as soon as possible.

As long as Ning Shu can make it, this elixir will be of a lot of use.

"Are the herbs needed for this elixir precious?"

Cost is also an important thing, and if he can't afford it, all his ideas will be shattered.

"Just need some ordinary herbs, it seems that the prince likes this elixir very much?"

"Of course, I want to see such a novel elixir right away."

Nie Jingchuan did not hesitate to express his expectations, and the harvest this time was indeed rich.

"If you still want to refine any pills, you can give me the medicinal materials, and I will let them collect them."

Nie Jingchuan said this to give Ning Shu a reassurance, he would not memorize her Dan Fang and let others refine it, he trusted Ning Shu and hoped that she could do a good job for him in the Regent's Mansion.

"I'll write a list later, and you can have people prepare according to the herbs on the list."

Ning Shu was also not polite, she couldn't refine the pill without herbs, and Nie Jingchuan came for her ability to refine medicine.

After asking, Nie Jingchuan once again remembered that Ning Shu had just finished bathing, and the clothes on her body were only simply worn, and it was indeed a little inappropriate for him to stay in her room for so long.

"Then I'll go back and rest."

Ning Shu sent Nie Jingchuan away, opened the window and looked at the gray sky outside, the wind outside was getting stronger and stronger, since the rain in the afternoon, the weather had gradually become colder, and there were no leaves left on the big trees outside, so it could be seen that winter was really coming.

It was at this moment that Ning Shu heard an inaudible sound of tiles stampeding from the eaves, and there were people on the roof.

This realization made Ning Shu prick up her ears and quietly listen to where the other party was going, after having an old woman, she felt that this time the road would not be peaceful, the so-called Yu Xiang would not let go of such a good opportunity to let the regent and the prince go to the capital safely.

Nine times out of ten, the people on the roof are also Yu Xiang's people, did the old woman surrender to Cheng, the two were in a group, or did Yu Xiang send someone over after learning that the old woman failed?

After listening quietly for a while, she found that there was not just one person on the roof, but several, and she needed to inform Nie Jingchuan and the others to be careful.

She could hear it because she had spiritual power in her body, and Wu felt extremely keen, and she didn't know if Nie Jingchuan had found the person on the roof.

Ning Shu raised her feet and thought of the door, but heard footsteps on the roof stop in her room, and the other party's target was likely to be her.

Realizing this, she didn't have time to inform Nie Jingchuan at all, a pair of feet rushed in from the window, Ning Shu immediately picked up a stool and threw it over, and threw it out if the window couldn't be closed, no matter how agile the other party's speed was, she couldn't imagine that the person in the room had this hand, and was smashed squarely without any defense, and the whole person swung out, and the only hand still grabbed a little eaves.

Seeing that he was about to fall out, the man in black had to speak out and ask his companion to save him, even if he had internal strength, he couldn't fly out of thin air.

"Hold me."

It was very difficult for one hand to support the weight of the whole person, and he quickly lost his whole hand to support it, and fell down before the other hand could reach it.
