"The last time... Should be when I came back from Beidou college, about November." Ying Xiao saw that Lu Ping and Su Tang were very serious, and temporarily put away his ecstasy at the resurrection of divine medicine. He tried to recall it and said.


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


    "You forgot? They are underground, so you can''t see them like this. " Su Tang said to Lu Ping.


    "I want to see if anyone is out." Lu Ping said.


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


    Lu Ping nodded, and Maureen squatted down, picked up some mud and sniffed.


    "Can you find anything?" Lu Ping asked him. Although Maureen''s medical skills have always been criticized by them, he is really proficient in pharmacology from his ability to poison.


    "It should be discarded drug residues. Only when they get here in some way can they become like this." Maureen said, began to look around the mud, looking for clues around.


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


    "This way." After walking around, Maureen found out and greeted the people. Lu Ping and Su Tang immediately gathered together. Ying Xiao was still regretting that he didn''t bring a container, and smelled the sound and looked over there.


    Here is the side of the mud against the pit wall. The snow has been swept away by Maureen. Below is the hard frozen soil. Maureen patted it again, but found no soft place.


    "Break it down here." Maureen pointed out that he couldn''t come with such strength.


    Su Tang clapped it with his palm, the frozen turtle split, Maureen dug down layer by layer, and finally dug up a handful of mud from under the frozen soil.


    "Look." Molin proudly showed the mud to several people. Lu Ping and Su Tang bowed down together and turned it over again. Under the hard soil layer, there is an undercurrent. Although there is no flow, it is the same mud as in the mire.


    "You should be able to find the source along here." Said Maureen.


    That''s what I said, but the undercurrent is several meters deep underground and can''t see any trace on the surface outside the pit. If you want to follow this, you can only dig a channel under the ground..


    "If I were not in this cold place, I could do something." Maureen shook his head and sighed. He took out several seeds from the medicine bag, looked at them and threw them away with regret. Almost no plants can survive in the bitter and cold land. These seeds have frozen to death only in this environment for a few days. Otherwise, you can use the characteristics of fog hunting grass to find the source of medicine.


    "Isn''t it just digging a hole? It''s simple." Ying Xiao said.


    "Oh?" The three looked at him together.


    "I''ll find a collection team. They''re best at this kind of thing." Ying Xiao said.


    "Please." Lu Ping said. He had planned that no matter how hard and troublesome he was, he would find it and dig it himself. However, since yingxiao has a better plan, of course, he won''t refuse.


    "You wait here. I''ll look for it. " Ying Xiao jumped out of the pit, looked out like Lu Ping, recognized a direction and left.


    "I''ll pretend to play this game and study it later." At this time, Maureen took out several medicine bottles from his arms, grabbed the mud and filled them into the vials. Lu Ping suddenly stood up and looked up.


    "What a big heart! Just let him go? " Two figures appeared on the upper edge. It was lengqing and Xu Weifeng who disappeared after they approached Erlu village. At this time, they stood up and looked at them. Lengqing spoke.


    "Where have you been?" Lu Ping asked.


    "That''s Erdao''s village. We''ll approach it when we''re crazy. Of course, I''m looking for a place outside the village to wait for you to come out. " Leng Qing said.


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


    "Yes." Lengqing said, jumped down with Xu Weifeng and came over.


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


    "I''m actually skeptical." Maureen said, "but there is a big man. Whatever he does, he will only be unlucky."


    "Will it be the fourth way from here?" Leng Qing touched the mud on the ground and said.


    "I''m not sure." Lu Ping said. There seems to be some connection between the organization and the fourth road, but Lu Ping is not clear about what is going on.


    "Wait." Leng Qing said nothing more. She and Xu Weifeng didn''t stay here. They went out of the pit together and kept a distance from each other without any communication. After more than an hour, lengqing suddenly said "coming", and then the figures of her and Xu Weifeng heard from each other again. I didn''t see Ying Xiao coming back with more than ten people.


    "That''s it." The camp roared down, and more than ten people poured down. Lu Ping and the three stood aside. These people ignored them when they saw them. The first one went to the edge of the mud, then touched the mud in the undercurrent they turned out, nodded, waved to the people and said, "dig along this."


    Followed by more than ten people, they became busy. Some of them set up custom-made, some controlled the soil, some raised their feet and stamped the ground, some waved their fingers and poked, and the last one was their leader. A copper stick in their hand was suddenly sent out and went straight to the bottom. The other people were busy again. Finally, it was his turn to take the lead. This time, he took the copper rod out of the ground. However, under this pumping, a large cylindrical frozen soil was brought out, and an underground passage had been pulled out.


    "How about the effect?" Ying Xiao came to the three and said proudly.


    "Awesome!" Lu Ping and the three of them were deeply impressed. These people have formed a system in this matter by using their powers, and their cooperation is extremely tacit. Everyone performed their duties and saw that the frozen soil was pulled out from the ground section by section. In the twinkling of an eye, it was several meters deep.


    "I have made it clear to them that they will see the direction. They are all experts in this regard." Ying Xiao said.


    "Hard work." Lu Ping said.


    "Not all for you." Ying Xiao said.


    "What?"


    "We have always wanted to know where the fourth road is hidden." Ying Xiao said.


    "Oh." Lu Ping nodded.


    "I''ll inform the village later. Do you mind?" Ying Xiao asked.


    "Not at all." Lu Ping shook his head.


    "Where are those two guys? They never showed up." Ying Xiao then muttered.


    "They came when you left." Lu Ping said.


    "Oh, they should do the same thing." Ying Xiao said.


    "Whatever you want. There''s only one thing. " Lu Ping said.


    "What?"


    "If you make up your mind about Beidou college, we will have a conflict." Lu Ping said.
