Master immediately understood what I meant, and he pointed in the direction of the inlet, and nodded at me again.

It seems that Master is planning to swim against the current.

However, for now, it seems that the only option is to go upstream of the river vein, the outlet is too small to pass, because of the existence of the undercurrent, we cannot swim ashore, and the hole in front of us that constantly has fresh river water pouring in, is already the last way we can go.

I nodded to Master, who turned around and grabbed the vegetation at the bottom of the pool towards the entrance of the cave.

The oxygen concentrator prepared by Liu Shangang can provide enough oxygen within 40 minutes to an hour, but no one is sure how long I will stay underwater, so I can only use turtle breath gong to reduce oxygen consumption.

I followed the master and crawled forward slowly, and when I passed by the sarcophagus, I took a cursory look at the coffin, and I saw that the coffin surface was pitted and very rough, and the whole sarcophagus looked like a whole piece of original stone was hollowed out, and the inner wall of the coffin was also uneven.

Master didn't pay attention to the coffin, just kept crawling forward.

The closer you get to the inlet, the stronger the undercurrent becomes, and when you get to the front of the hole, the master puts his whole body on the bottom of the pool and slowly moves forward.

I also lowered my body in the same way as Master, so that the resistance of the water was a little less, but when the warm chest was almost completely attached to the cold bottom of the pool, it still made people feel very uncomfortable.

After the two of us climbed into the hole, the undercurrent was still strong, and I glanced towards the master, who was still lying on the ground, slowly crawling in the water. After that, I didn't think much about it, and I silently climbed forward like Master.

Crawling underwater like this, I can't calculate how far I've crawled, or how long I've been underwater.

But I could feel that as we got closer and closer to the upper reaches of the Earth River, the Yin Qi in the water became weaker.

By the time the undercurrent slowed down, Master and I had come to a wide river channel, where there was hardly a trace of yin in the water.

Master and I surfaced and climbed ashore.

The water in the river was really cold, and after I went ashore, my whole body was shivering, and the master was no better, he hugged him tightly and kept shaking.

Master's jaw trembled with cold, and he said to me in a shaky voice, "Down...... River, grab a few handfuls...... Plants...... Above...... Come up ......"

I didn't dare to be ambiguous, so while there was still a little heat on my body, I turned around and went down the river again, sank to the bottom of the water, and pulled a large handful of aquatic weeds up.

Master looked at the aquatic plants I had piled up on the shore and shook his head resolutely: "No...... Enough. ”

Although I didn't know what Master wanted the aquatic plants to do, but since he wanted them, they would definitely be useful, so I dived to the bottom of the river again and pulled a large amount of aquatic plants to the shore.

Master and I dragged the aquatic plants to a relatively dry place, and then he took the fox fire lantern in my hand, removed the lantern shade, and directly roasted the fox fire on the water plants.

Under the scorching of the fox fire, the originally wet aquatic plants turned into dry grass at a speed visible to the naked eye, and after a few minutes, an orange-red flame burned in the aquatic grass pile. Because many aquatic plants have not been scorched by the fox fire, they still have some moisture on them, and they burn relatively slowly.

In this way, Master made a fire with a fox fire lantern, and with the high temperature emitted by the fire, the temperature on our bodies gradually rose.

The master quickly relented, and while returning the fox fire lantern to me, he said to me, "It's good that Xian'er gave you the lantern beforehand, otherwise we would have really folded it here this time." ”

I took the lantern and looked at the green and cold flame, and I was very puzzled, why could the fox fire ignite the aquatic plants when it was obviously cold?

Master took out a few pieces of soggy candy from his pocket and asked me, "What do you want?" ”

I said, "Thanks to the aquatic plants growing in the river, even if there is a fox fire, there would be no firewood." ”

My master gave me a few candy cubes: "Replenish your strength, now there is nothing else to eat except this sugar." The things in the river are not aquatic plants, and they are the same as the cloth silverfish of the old Huang family in the northeast, and they are also things that only grow in the tomb. ”

After speaking, the master looked at the river not far away, and then said to me, "It seems that the earth river itself does not carry yin qi. The reason why the water downstream is heavy is because of the sarcophagus in the pool. ”

I said, "That sarcophagus, in the early years, it should have been used to store corpses, and only the pure yin qi on the sarcophagus could suppress the yang energy on the corpses." But why did our ancestors who kept the right line get the corpses out, just to collect blood? ”

Hearing my words, Master shook his head at me: "The sarcophagus should be used to store corpses, this can't be wrong. But have you ever thought that although the corpse is heavy yang, it is the inner yin and the outer yang, this kind of evil corpse is in line with the yin and yang is easy to reason, the yin in their body and the yang outside the body are balanced, how heavy the yang you feel, how heavy the yin in its body is. Moreover, the cause of yang energy is the yin energy in its body...... Do you understand what I say? ”

I was suddenly a little unhappy: "Why don't you understand." Don't you just mean to say that in order to maintain the balance of yin and yang, the yin and yang qi inside and outside the body must maintain the same intensity. ”

Master smiled and nodded, "That's what it means." Do you think, if it is placed in that sarcophagus all the year round, on the surface, it is the yin of the sarcophagus that calms its yang, but in fact, the yin in this sarcophagus will also nourish the yin in the corpse's body, and the yin in the corpse will become stronger and stronger, and at the same time, it will also make the yang outside its body stronger. Over time, sooner or later, the sarcophagus will not be able to control it one day. Our ancestors should have lifted it out before the corpse broke into the coffin, used great magic to suppress it in the tomb, and then used black steel cables and spirit runes to suppress the yin in its body, and finally borrowed the earth river and sarcophagus to suppress its yang energy. ”

I thought about it, and it is also the same reason, if you simply put the corpse in the sarcophagus, there is indeed a danger of breaking the coffin.

Master stared at me quietly through the fire, and after a while, he opened his mouth and said to me, "You kid, don't think that you can do a great job after two trips, you are still far away!" ”

I wondered, didn't I just not think about the layer of the corpse and the broken coffin, and the master would use such words to squeeze me?

Listening to my master's words, I inevitably complained a little in my heart, but I didn't say anything.

I feel that since I took over the business of Nancy Hu independently, Master seems to have become very preachy, and he also cares about others contradicting him.

That feeling is like a retired veteran cadre who is particularly worried about being forgotten by others.

In fact, in those years, the master not only became a little eccentric, but also became very verbose, especially fond of talking about the glorious deeds of his youth, and occasionally, he would be a little unkind. I know that when Master is old, he becomes forgetful, and every time he forgets something, he will get angry inexplicably, and he can't send this anger at others, so he can only send it at me. I can feel that Master's body has deteriorated day by day in the past two years, although his strength is still surprisingly great, but in terms of physical strength, it can no longer be compared with before.

I didn't want Master to come to the tomb this time, but I also knew that he would never ignore the matter of the Mass Grave Mountain, I knew his temper, and I also knew that I couldn't stop him.

I thought that after I went to the grave, I would follow him, watch him, and take care of him. But I didn't expect that the person who was taken care of was still me.

The flames in the fire were still strong, and Master and I sat by the fire, waiting for our clothes to dry. From time to time, Master would say a few inconsequential remarks, sometimes complaining about trivial matters, and also reminiscing about his youthful years.

I didn't like to listen to these words, so I just coped with it with "uh-huh-hmm", but Master still kept talking.

In this situation, it seems strange for two people to gather together on the fire to hang out and do their own things. But when I grew up, I remembered the scene at that time and realized that this was probably the only time Master had the opportunity to talk, because on weekdays, whenever I had something to do, I would not obediently listen to him say these words, and I would always find an excuse to prevaricate him, such as to write homework, such as to practice, and I had never listened to Master's nagging like that time, although I still didn't listen to him much, and I didn't remember much.

But at least, the words that Master had been holding back in his heart for many years finally poured out, even though to me they seemed to be inconsequential words.

I also forgot how long Master was nagging, until I found that the diving suit on my body had been dried out, and then I said to Master, "Master, shall we continue walking along the river, or shall we wait for Daoist Chen and the others to come to us?" ”

If I remember correctly, Master seemed to be talking about my uncle's marriage, and when he was talking about his excitement, he was suddenly interrupted by me, and he was stunned for a moment, and then responded to me: "Let's go along the river." ”

Master stood up on his knees as he spoke.

I saw that he was a little struggling, and wanted to go up to help him, but I didn't expect to get a big roll of his eyes, he stretched out his hand to block me, and yelled: "What to help, I'm not old yet!" ”

I felt a little embarrassed, smacked my tongue secretly, and didn't dare to support the master again, but just lifted the fox fire lantern and helped the master light the way.

As he walked, Master looked around at the river illuminated by the fox lantern.

There are stones scattered on the banks of the river, and from the top of the tunnel there are dripping from time to time, and the dripping water over the years has left smooth and deep potholes on these stones, and when new droplets fall in, the water in the potholes will stir and ripple.

As if thinking of something, the Master suddenly rushed to a stone in three steps and two steps, reached out and grabbed the smooth edge of the stone, and pulled it hard, and the huge stone suddenly fell to the ground, and I saw that there were some reliefs at the bottom of the stone.

"There is a way, take a picture." Master glanced at me and pointed to the stone as he spoke.

I leaned over with the lantern, and the green flames were not bright enough to illuminate the carvings at the bottom of the stones. Although the carvings have been covered in the ground, they have been corroded to a certain extent, making it difficult to make out the contents on them. In the area illuminated by the fox fire, I could only make out a relief in the shape of a mountain, and although the edges and corners of the mountain had been rotted by time, I could still see that the relief was very finely made.
