Strange to say, according to the old man Duan Tianao, the Demon Realm is spooky and terrifying all year round, and people who have been there will often hear the cries of demons. I think he was a promising young man back then, and he followed others there on a whim.
In the Demon Realm, nothing was found, but a lot of yin and yang leaves were collected.
However, after Duan Tianao brought back the Yin and Yang leaves, no matter how he planted them, there was no effect. He tried many methods, but they all ended in failure. He had no choice but to dry them and store them. He could not plant them himself. There was no such smell in other places.
Medicinal materials are naturally more precious.
"Girl, have you used up so many Yin-Yang leaves?" Duan Tianao exclaimed, you must know that the Yin-Yang leaves are just like the name, one side is green, the other side is withered gray-white, but it grows extremely well
of.
At that time, Duan Tianao also studied the growth of yin and yang leaves, but he never found a method to cultivate them. He didn't understand them at all, so he didn't bother to study them. But at that time, he clearly remembered that he brought back a lot of yin and yang leaves.
It doesn't seem to be of any use, so why is it gone?
Giving Duan Tianao an annoyed look, Luo Yu said: "Master, you must have amnesia. Who said you wanted to try gunpowder last time, but most of the medicinal materials in the medicine house were burned.
If I hadn't acted quickly and rescued a little bit, you wouldn't even be able to see the scum now."
This old man is really forgetful. Really, last time she just said that there was gunpowder in her hometown, which was amazingly powerful. And they happened to have the materials for making gunpowder, potassium nitrate, charcoal and sulfur mixed mechanically.
Duan Tianao started making gunpowder on a whim.
Perhaps because the proportions were wrong at the time, the gunpowder was not made, but the fire bombs were made, directly blowing up the medicine house, and the flying sparks instantly ignited the dry medicine house.
Luo Yu originally just went to get sulfur for Duan Tian Ao, but he didn't expect to see the fireworks all over the sky when he came back. His face suddenly sank and he started to rescue the medicinal materials from Yaoju. That was two years ago, but since this incident happened
After that, Luoyu was determined not to allow Duan Tianao to pick up these things anymore.
Because she didn't want them to have to sleep in caves or on the roadside one day, and she wasn't ready to let it go yet. That's why there were only a few Yin-Yang leaves left, because they happened to be right next to the fire bombs.
This is considered Luo Yu's skill to be fast.
"Uh, haha, people get old and their memory is bad." Duan Tianao tilted his head in embarrassment and said awkwardly. He had really forgotten about this, but after Luo Yu said this, he remembered it again.
He has gunpowder. He has to take some time to study this thing carefully. It is simply too powerful and makes him very interested.
However, this matter had to be done when Luo Yu was not around, but he remembered that Luo Yu wouldn't let him touch this, so he had better do it secretly.
At this time, he had another focus, and he was already quickly thinking about this more interesting thing. For the time being, he put aside the matter of Yin Yang Grass, but he had to think about the gunpowder.
"Really? I think you only know how to play and don't know how to clean up the mess." Luo Yu pointed out unceremoniously that Duan Tian Ao had done quite a lot of stupid things in the past three years, which made Luo Yu think.
