"For the last time...... It should have been when I came back from Beidou Academy, probably in November. Ying Xiao saw that Lu Ping and Su Tang were very serious, and he temporarily put away his ecstasy at discovering the resurrection of the magic medicine, and said after trying to recall it.

At this time, Lu Ping had already jumped back from outside the pit and shook his head at Su Tang.

"You forgot? They're underground, so you can't see them that way. Su Tang said to Lu Ping.

"I wanted to see if anyone was out there. Lu Ping said.

"I think it's around here. If it is too far away, it will not affect the change of water and soil here. Su Tang said.

Lu Ping nodded, and Mo Lin also squatted down at this time, scooped up some mud and sniffed it.

"Can you find anything?" Luping asked him. Although Morin's medical skills have always been criticized by them, he is indeed very proficient in pharmacology from the perspective of his ability to make poison.

"It's supposed to be a discarded medicine residue, and it will become like this when you get here in some way. Maureen said, and began to look around the quagmire, looking around for clues.

"I knew I should have brought two buckets. Ying Xiao was immersed in his regret at this time.

"This way. Morin, who had walked around, made a discovery and beckoned everyone. Lu Ping and Su Tang immediately came up, Ying Xiao was still lamenting that he didn't bring a container, and he also looked over there when he heard the sound.

It was the side of the mud pool against the wall of the pit, the snow had been swept away by Morin, and below was the hard frozen soil, which Morin patted but found nothing soft.

"Smash it open. Maureen pointed and said, he couldn't do it with such strength.

Su Tang slapped it with his palm, the frozen soil cracked, and Mo Lin dug it layer by layer, and finally dug a handful of mud from under the frozen soil.

"Look. Mo Lin proudly showed this handful of mud to a few people, Lu Ping and Su Tang lowered their bodies together, and turned this piece over with three strokes and five divisions. Under the hard layer of hard soil, there is an undercurrent, although it is not visible, but it is the same mud as in the mire.

"Follow here, you should be able to find the source. Maureen said.

That being said, but this undercurrent is hidden several meters underground, and there is no trace on the surface of the pit, and if you want to follow this, you can only dig a passage underground.

"If it weren't for this bitter cold place, I would have had something to do. Maureen shook his head and sighed. He took out a few seeds from his medicine bag, looked at them, and threw them away regretfully. There are hardly any plants that can survive in the bitter cold land, and these few seeds have frozen to death after only a few days in this environment. Otherwise, you can use the characteristics of this fog hunting grass to find the source of medicine.

"Isn't it just digging a hole, it's easy. Ying Xiao said.

"Oh?" the three of them looked at him together.

"I'm going to find a gathering team, they're the best at that. Ying Xiao said.

"Please, then. Lu Ping said. He had planned that no matter how hard and troublesome it was, he would find it and dig it himself. However, since Ying Xiao has a better plan here, of course he will not refuse.

"You guys wait here. I'll look for it. Ying Xiao jumped out of the pit as he spoke, and looked into the distance like Lu Ping, and left after recognizing the direction.

"I'll pretend to be a little bit of this thing, and I'll go back and study it. At this time, Morin took out several medicine bottles from his bosom, grabbed the mud and put them in the vials. Lu Ping suddenly stood up at this moment and looked up.

"The heart is really big, just let him go?" Two figures appeared on the edge above, it was Leng Qing and Xu Weifeng, who had disappeared since they approached Erlu Village, and it was Leng Qing who stood above and watched them at this time, and it was Leng Qing who spoke.

"Where have you been?" Luping asked.

"That's the village of Erdao, and we're crazy to get close. Of course, I'm looking for a place outside the village and waiting for you to come out. Leng Qing said.

Lu Ping nodded, pointed to his feet and said, "This is it." ”

"I hear you. Leng Qing said, jumped down with Xu Weifeng, and walked over.

"You really don't doubt him at all?" Leng Qing said.

"I'm actually skeptical. "But there is a big guy here, whatever he does, it will only be him who is unlucky." ”

"Will it be four ways to find it from here?" Leng Qing said as he touched the mud on the ground.

"I'm not sure. Lu Ping said. It seems that the organization and the four roads have some connection, but it is not clear what is going on Lu Ping.

"Wait. Leng Qing didn't say anything anymore. She and Xu Weifeng didn't stay here, and the two of them went outside the pit together, keeping a distance from each other and communicating with each other. After about an hour, Leng Qing suddenly said "here", and then she and Xu Weifeng's figures went their separate ways. After a while, I saw Ying Xiao come back with more than a dozen people.

"That's it. Ying Xiao pointed downward, and more than a dozen people rushed down. Lu Ping and the three of them all stood aside. These people didn't pay attention to the three of them when they saw them, and the first one went to the edge of the quagmire to take a look, and then touched the mud in the undercurrent that Lu Ping and they turned out, nodded, and waved his hand to everyone: "Dig along this." ”

With more than a dozen people, they got busy. There are custom-made settings, there are those who control the soil, there are those who raise their feet and stomp on the ground, there are those who poke and poke with their fingers, and the last to shoot is their leader, and a copper rod in his hand is suddenly sent out, and it goes straight to the bottom. It was another busy time with the others, and finally it was the turn of the leader again, but this time he pulled the copper rod out of the ground, but under this pump, a large piece of cylindrical frozen soil was brought out, and an underground passage had been pulled out.

"How's it going, is it effective?" Ying Xiao said a little smugly as he came to the three of them.

"Awesome!" Lu Ping and the three of them were deeply impressed. These people have formed a system in this matter by using their abilities, and they cooperate with each other very tacitly. Everyone did their duty, and they saw the frozen soil being pulled out of the ground one by one, and in the blink of an eye, it was several meters deep.

"I've made it clear to them, they're going to see the right direction, they're experts in that. Ying Xiao said.

"Good work. Lu Ping said.

"It's not all for you. Ying Xiao said.

"How?"

"We've always wanted to know where the four roads are hiding. Ying Xiao said.

"Oh. Lu Ping nodded.

"I'll let the village know later, don't you mind?" asked Ying Xiao.

"Not at all. Lu Ping shook his head.

"Where are those two guys, why haven't they been there. Ying Xiao then muttered.

"They were here when you left. Lu Ping said.

"Oh, they're supposed to do the same. Ying Xiao said.

"Feel free to do whatever you want. There is only one thing. Lu Ping said.

"What?"

"Beidou Academy's things, if you make up your mind, then we will have a conflict. Lu Ping said.
