When he opened it, he was immediately frightened by the big words on it.

"Gunpowder ......" Although he didn't know what this thing was, it was clearly a powerful thing.

Chi Zhongjing couldn't help but flipped it down, and it was written the ratio of gunpowder, the purpose of gunpowder, and the power of gunpowder......

The more Chi Zhongjing looked at it, the more excited he became, this is a good thing on the battlefield.

Chi Zhongjing couldn't wait to watch it, but because he didn't have the expertise in this area, although he knew that this thing was very awesome, he couldn't make it.

It's as if a lot of blood has been ignited, but there is no one in front of you who can fight.

Chi Zhongjing felt that if this thing could really be made and brought to the battlefield, it would definitely be a human killing weapon.

Suddenly, Chi Zhongjing felt that he should go back to Beijing for this thin formula.

"Zhi'er, I'm going to go back to the capital tomorrow, and I'll be back when things are done." After Chi Zhongjing had this idea, he immediately went to find lychee.

"Huh?" Lychee looked up from her drawing paper, "Why is it so sudden?" Didn't you say that you should propose as soon as possible? ”

Is it possible to propose marriage without Chi Zhongjing? Chi Zhongjing immediately said, "I'll rush back before that, maybe I can surprise you." ”

"What's the surprise?" Lychee asked subconsciously.

Chi Zhongjing smiled slightly, "Since it's called a surprise, it naturally can't tell you now." ”

After discussing with Lychee, Chi Zhongjing almost didn't hesitate, and prepared the horses in the afternoon and started to hurry.

Lychee was still a little reluctant, this person obviously said that he wanted to accompany her for a few more days, but he didn't expect it to be only a few days, so he left.

However, Lychee's sad mood didn't last long, because Luo Yuhu had already made the magic Han aspect of the mask.

"Sister Lychee, I've tried it on Akiba's face a few times, and the effect is not bad, and there are no side effects." Luo Yuhu couldn't wait to say.

This Han mask powder is not safely made according to the recipe given by Lychee, and Luo Yuhu himself used his medical knowledge to improve it.

Now after applying this mask powder, it can not only improve dull spots, but also smooth the skin to remove black and yellow, so that the skin can be restored to tenderness and firmness.

Litchi nodded, "That's right, let's go see Miss Chen." ”

If Miss Chen had listened to her and used skin care products and sun protection every day, her skin would have returned to a stable condition, and it would be just right to wear a mask now.

"Sister Lychee, you mean ......" Luo Yuhu widened his eyes.

Lychee nodded at her, "You naturally want to go, the future proprietress has to go to meet our big customer." ”

"Can I do it?" Luo Yuhu was a little excited, but also a little scared.

"It's okay, besides, isn't there still Akiba to help you?" Lychee nodded at her and encouraged.

In the afternoon, Lychee took Luo Yuhu to Chen's mansion.

This matter can't be rushed, because after the first month, those girls of the Chen family will leave and return to the capital one after another, and she has to use Miss Chen to make a name for this freckle removal and blackening.

Luo Yuhu obviously made preparations with great effort, she first washed Miss Chen's face with Qizibai's facial soap, and then used two hot towels to apply her face alternately for a quarter of an hour, and waited until the pores on her face were opened, and then put on the mask powder that exuded a strong medicinal fragrance.
