The three of them stopped and walked all the way, and it took half a day to arrive at the hot spring cave.

Ke Mu was a little disappointed, "Brother, why didn't I see a prey?"

"There are many people walking on this road, and the prey has already left. If you want to hunt, I will ask Ah Qing to take you tomorrow." Holding the bow and eager to try, Ke Tu was very happy with his younger brother's change.

"Brother Xie Yi went hunting, that's why I went." Ke Mu pouted, "Ah Qing can't beat Brother Xie Yi."

Xie Yi patted Ke Mu on the back of the head, "Don't talk nonsense, quickly light a torch and go in.

" Ah..." Ke Mu muttered softly while picking up firewood and lighting the torch.

Ke Tu followed Xie Yi, "Ah Qing really can't beat you."

"Don't mess around with Ke Mu."

"I didn't mess around, Ah Qing can't beat me, and I can't beat you either." Ke Tu said seriously.

"Ah Qing can't beat you, so he can't beat me. Does that mean you can't beat me too?" Xie Yi slowed down and walked with Ke Tu.

Ke Tu bowed his head and walked without speaking, and it took him a long time to say "hmm".

Xie Yi chuckled, "Ketu."

"Yeah."

Xie Yi leaned over to kiss the corner of his mouth, and finally stuck out his tongue to lick it.

Ke Tu stretched out his hand to hold him, hugged him, and intertwined lips and tongues. There was the sound of kicking stones on the winding mountain road not far away, and then Kemu

shouted, "This road is so long, brother Xie Yi, where have you been?"

In front of Ke Tu's forehead, he took a breath and said, "Here, quickly follow."

After a while, Ke Mu caught up from behind, "Brother, why didn't you wait for me."

"You are walking too slowly , don't follow me out next time." Ketu said stiffly.

"It's not slow, it was too dark just now." In order to prove that he walked fast so that he would not be able to come out to play with him next time, Ke Mu held a torch and passed from the two to the front.

Ke Tu held Xie Yi's hand and walked behind.

"It's so big here!" Ke Mu arrived first, holding a torch and trying to circle around inside, "Brother, it's bigger than where we live."

Xie Yi found a place to dig up stones, and he picked up A gray-white stone leaned against the fire and looked at it, then scraped off a little powder with the back of a knife, and tasted a little with the tip of his tongue.

"Can stones be eaten too?" Ke Tu asked strangely after watching for a long time.

"This is for medicine, gypsum stone."

"Medicine?"

Xie Yi has been tinkering with this thing for the past few days when he has nothing to do. Ke Tu didn't know much about it, so he scraped off some powder and tasted it like Xie Yi did.

"Bah. Bah..." He vomited for a while before feeling better.

Xie Yi smiled unkindly from the side, "How does it taste?"

"It's a bit like chili, but it's worse than chili." Ke Tu concluded with a serious face.

"Don't be like Ah Hua, dare to taste everything." Xie Yi smiled enough, and said, "You can't take medicine indiscriminately, it will kill you. This thing is very cold."

Ke Mu ran around in the cave Come here, "Brother, brother Xie Yi, there is a small cave inside."

There were no other caves when I came last time.

The two looked at each other and followed Kemu into the cave. Bypassing the hot spring, there is a narrow passage between the two most recessed mountain walls, which only allows one person to pass through.

This more than ten meter long passage gradually goes upwards, and then there is a small cave of more than ten square meters. Above the cave, there are faint cracks.

Xie Yi held up the torch and took a look around the mountain wall, and sure enough, he found some characters on it. He secretly compared the tinfoil in his mind, and it seemed that the symbols on it were basically engraved in the cave, except for the one in the middle.

He looked back at Ketu, who was scraping something on the stone wall with a knife, his face was a little unclear in the flickering firelight.

"Xie Yi, the stones here are all the gypsum stones you mentioned." Ke Tu greeted Xie Yi, "Look at the roads on it, I don't know who made it."

Xie Yi leaned over to look, and it was really gray There are dark red light marks on the stone, which are connected with the symbols in the cave.

This color should be left by the blood, where did the blood come from?

"Ketu, don't people in the clan come to this place?"

"Well, Wu Si said that this place can't be visited. But we have come here several times, and nothing strange happened." Ketu asked, "You I found something wrong, how do I ask this?"

Xie Yi frowned slightly, and then let go, "It's nothing, let's go."

"Wait a while, we dig a few stones here and take them away."

"No, I just We have dug enough, let's go back quickly, or it will be dark." Xie Yi stopped Ke Tu when his knife was scratching the stone wall, and turned around to greet Ke Mu, "Don't look, let's go back quickly. "

When they returned to the cave, it was already dark, and the medicine Xie Yi dried was carried back to the tent by the tribe and placed beside it was a small piece of meat that was distributed today.

Ke Mu consciously took the meat to cook, he has always learned things very quickly, and he has learned everything Xie Yi taught in a decent way.

Xie Yi checked the wound for Ketu, and after changing the dressing, he began to deal with the plaster collected today.

He scraped off a layer of dust on the surface of the gypsum stone, then smashed it into pieces, and together with Ketu, he removed the impurities inside little by little.

After supper, he set up clay pots over the fire, put clean raw plaster in them, and covered them.

Xie handed over the burden of burning the fire to Kemu, and picked out the first batch of bletilla striata from the cut medicine tablets, and put it in a stone mortar to grind it into powder.

When the gypsum was wrought to the point of crispness, Xie Yi poured it out, let it cool and pounded it into powder, then mixed half and half of bletilla striata and gypsum, and filled several small bottles.

And the bottle cork...

Xie Yi rummaged through the firewood in the corner, picked out a few pine branches and cut them into a cork to seal the bottle. He picked it up and shook it, but nothing leaked.

"What is this for?"

"Sprinkle a little on the wound to stop the bleeding."

Xie Yi pounded some Panax notoginseng powder and put it in a small bottle.

The row of bottles in front of them looked exactly the same, and it would be bad if there were more medicinal materials in the future. Xie Yi picked up the saber and carved his name on the cork.

"Look, these two characters are Sanqi, and the one on this one is Baiji gypsum powder." The characters on the cork were too small, so Xie Yi simply took a stick and re-wrote it on the ground, and then told the two of them.

"The word is Sanqi, what is it?" Ke Tu leaned over and expressed doubts about what Xie Yi wrote.

Uh, one mouthful can't make you fat. For primitive people who have no awareness of Chinese characters, it seems that they should take their time.

Xie Yi took out a piece of Panax notoginseng from the basket and asked, "What is this?"

"Sanchi!" Kemu's voice was loud. He followed Xie Yi these few days and memorized the names of these medicinal materials by heart.

Xie Yi re-wrote these two characters on the ground, holding a stick and bit by bit, "The thing drawn on the ground is a character, this character is pronounced three, this is seven, and two put together is three seven, which refers to What I'm holding in my hand."

Ke Tu suddenly became interested, read the words on the ground again, and silently wrote down, "Sanqi... what is the bletilla striata?"

Xie Yi wrote the word bletilla striata on the ground.

"Where is Xie Yi?"
