It's strange. According to the old man Duan Tianao, the Demon Realm is gloomy and terrifying all year round, and people who have been there will often hear the cry of the Demon Realm. I think he was a promising young man back then, and he followed others to the Demon Realm on a whim. As a result, he didn't find anything, but he picked up a lot of Yin and Yang leaves.

However, after Duan Tianao brought back the Yin and Yang leaves, they were planted without any effect. I tried many methods, but they all ended in failure. He had to dry them and collect them, and could not plant them by himself, and there were no other places. This medicinal herb naturally seemed more precious.

"Girl, have you used up so many Yin and Yang leaves?" Duan Tianao shouted. You should know that these Yin and Yang leaves are like this name. On one side are green and withered grayish white, but they grow very well.

At that time, Duan Tianao had specialized in the growth of Yin and Yang leaves, but he had never found a method of cultivation. He didn't understand these at all, so he was too lazy to go to specialize in research. But at that time, he clearly remembered that he brought back a lot of Yin and Yang leaves, and it seemed that he hadn't used it before, so why was it gone?

Duan Tianao looked at him in anger, and Luoyu said, "Master, you have amnesia. Who said last time he wanted to try gunpowder, but he burned most of the medicinal materials in Yaoju. If I hadn't been quick enough to rescue him, you wouldn't even see the scum now."

This old man was really forgetful. It was true that last time she just said that there was something like gunpowder in her hometown, which was amazingly powerful. And they just happened to have the materials for making gunpowder, potassium nitrate, charcoal and sulfur machinery. Duan Tianao started to make gunpowder on a whim.

Perhaps because of the wrong proportion at that time, the gunpowder was not made, but the fire bomb was made, which directly exploded Yaoju. The flying sparks instantly ignited the dry Yaoju.

Luoyu was just going to get sulfur for Duan Tianao, but when she came back, she saw the fireworks all over the sky. Her face suddenly darkened and she began to rescue Yaoju’s medicinal materials. That was two years ago, but since this incident happened, Luoyu has been determined not to allow Duan Tianao to take these things.

Because she didn't want them to go to sleep in the cave or on the roadside one day, she wasn't able to let go. This is why there was only a little bit of Yin and Yang leaves, because that thing happened to be next to the fire bomb, so Luo Yu was still very good at Luo Yu's ability.

"Uh, hehe, I'm old and have poor memory." Duan Tianao said embarrassedly and said embarrassedly. He really forgot this, but after Jing Luoyu said this, he remembered gunpowder again. He had to study this thing carefully when he was smoking. It was so powerful that he was very interested.

However, when Luo Yu was away, he remembered Luo Yu would not let him touch this, so he did it secretly.

At this time, he had another center of gravity, and was already quickly planning this more interesting thing. For the time being, he put this Yin-Yang grass aside, but he had to think about this gunpowder carefully.

"Is that right? I think you are the old man who only knows how to play and doesn't know how to clean up the mess." Luoyu pointed out without hesitation that Duan Tianao has done a lot of stupid things in the past three years, which makes Luoyu want to jump.
