This is a huge cave, with countless small holes everywhere. Wang Lin's spiritual consciousness came in from one of them.

In the center of the cave, there is a huge coffin. The coffin looks extremely ordinary from the outside and does not even have any pattern decorations. However, the majestic cold and cold air emits rapidly from the coffin, turning into waves of white air and being sucked away by the small holes around the walls.

Wang Lin hesitated for a moment, observed the coffin for a long time, then looked in. It was beyond Wang Lin's expectations that he actually got in without any obstacles.

There is nothing in the coffin, but there is a big round hole at the bottom, and the cold and cold air radiates from here.

The yin and cold energy here is quite dense, turning into layers of waves to prevent Wang Lin's spiritual consciousness from entering.

In the cultivation room where Wang Lin was in, a decisive look flashed in his eyes. In order to figure out the mystery of the yin and cold energy here and to figure out why the stone bead evolved after absorbing the yin and cold energy here, he slapped the storage bag without saying a word, took out the Yin and Cold Dew hyacinth that he had just collected, and tilted his neck and drank a small sip.

With Wang Lin's current system, he still couldn't help but shivered. His body was cold and he soon lost consciousness and became numb. Wang Lin did not waste any time and immediately used his spiritual power. As he breathed, his spiritual consciousness became more solid. After he had continuous replenishment, his spiritual consciousness penetrated into the hole in the coffin like an awl.

The spiritual sense was difficult to get inside the cave, and it was almost dispersed by the yin and cold energy several times. When it sank to about 400 meters, the yin and cold energy was extremely rich, forming a "door" again.

Wang Lin gritted his teeth and drank a heavy sip of dew with cold spiritual power. Then his spiritual sense rushed and broke into the door. The moment he entered, Wang Lin was shocked by the scene in front of him.

A huge naked male corpse floated in the air. In comparison, Wang Lin was only the size of a finger. On the body, there was a purple-green plant growing on the body. These plants were wriggling all the time. As they wriggled, the giant's body shrank significantly, but then returned to normal. In this cycle, the yin and cold air quickly radiated from the plants.

Wang Lin was stunned for a moment, and his spiritual sense carefully looked at it. The more he looked, the more frightened he became. The huge corpse was obviously deliberately left here. The purpose was to be the nutrients of the purple-green plant.

Obviously, the answer to why the Ziyin Sect has the Yin-Yin Qi of Earth-Quality is on these purple-green plants.

Even the reason why the Tianni Bead evolved must have a great relationship with this plant. After observing for a long time, Wang Lin slowly retracted his spiritual consciousness. This place was extremely strange. After Wang Lin entered here, he always felt a sense of crisis.

Just as I was about to leave, a sudden murmuring sound came as if it was present and vague.

Wang Lin immediately with no words, his spiritual sense was stopped, but what shocked him was that the cold and cold energy here suddenly rolled, blocking his spiritual sense. At this time, the murmuring sounds were getting closer and closer, and Wang Lin could already vaguely hear the content.

"Save me..."

Wang Lin decisively picked up the gourd and drank the liquid inside in one gulp. His spiritual sense immediately shook and penetrated into the surrounding yin and cold air. The unimaginable ice cold suddenly penetrated into the spiritual sense, intertwined with the yin and cold liquid that was not digested in Wang Lin's body. Wang Lin's face turned pale and a mouthful of blood was spewed out. When the blood was sprayed out, it had already formed ice crystals.

Despite this, the spiritual consciousness finally broke through the obstacle and quickly retracted it along the cave. In the blink of an eye, it returned to its original body. Wang Lin's body cold and sprayed out a few mouthfuls of blood crystals again, and a look of horror appeared on his face.

He didn't dare to explore again, and immediately breathed in his breath to calm the cold air in his body. After a long time, he slowly opened his eyes and looked at the small holes on the surrounding walls with lingering fear, leaving silent.

Time passed little by little, and in a blink of an eye, Wang Lin had been in the Corpse Yin Sect for four days. In the past four days, except for his spiritual sense entering the ground three days ago, he had no action. He collected liquid from the beads every day, and the beads also changed from two leaves to three.

According to Wang Lin's calculation, the total number of leaves on the bead should be like the previous clouds, all ten. With the previous experience of adding clouds, Wang Lin knew very well that the later the leaves would be, the slower they would be added. If it was only moistened by the yin and cold energy here, it would probably take several years to complete the wood-attribute spiritual energy.

But the Si Yin Sect is not a place to stay for a long time. After thinking for a long time, Wang Lin planned to explore the underground giant again, and this time he tried to find a way to get his body in. In this way, he would personally go down to grab a few purple-green plants, which would definitely allow the stone beads to evolve wildly.

However, the danger of doing so was too great, and Wang Lin was a little hesitant.

After pondering for a while, he still chose to give up his plan to go down in person. He knew that with his current cultivation level, no matter how cautious he was, he would not have a great chance of obtaining purple-green plants, and he would have a very likely life to be lost. Compared with each other, Wang Lin naturally had a choice.

After making up his mind, Wang Lin slapped the storage bag and suddenly a slim sword sheath flew out and floated in front of him.

The sword scabbard Wang Lin was satisfied and only sacrificed and refined once in his retreat after seizing Teng Li's foundation building. Although he did not succeed in sacrifice, he also mastered some methods of use, and the effect was not the best. So far, he could only sink the flying sword to three-fifths of the position.

Wang Lin has been studying this scabbard for a long time. Even Situ Nan once said that this scabbard is quite strange and its value is far beyond that of the green small sword refined by blood.

"Sun Hao mentioned before that the flying sword and scabbard were discovered by his master in an ancient cave. Except for his master himself, it cannot be refined before the Dan-Creating Stage. This should be true or false. These two items are not that they cannot be refined, but that the time is too long and spiritual power is consumed too much. If the Dan-Creating Stage is successful, then the process can be greatly shortened by the Dan-Creating Stage.

Unfortunately, the blood refining technique can only have one thing, otherwise if it is also used on the scabbard, everything will be much simpler." Wang Lin's eyes flashed and he said to himself.

Wang Lin stared at the sword sheath without blinking for a moment. In order to increase the power of the flying sword, the sword sheath must try to refine it again. Wang Lin thought to himself that although he did not have the golden elixir, he had the cold elixir obtained by practicing the Huangquan Ascension Jue.

The Yin and Cold Spiritual Power in the body is now mainly based on the cold pill. He studied it carefully during this period. However, after Situ Nan finished talking about the Huangquan Ascension Punishment, he seriously told Wang Lin that the gap between the cold pill is huge compared to the golden pill. The most significant one is that the cold pill should not leave the body easily unless it is absolutely necessary, otherwise once the time is a little longer, the cold pill will immediately dissipate and need to be practiced again.

When he was the first time he sacrificed and refining, he had just successfully seized the foundation, but now after practicing the Huangquan Ascension Punishment, not only has the mutation of spiritual power in his body, but his cultivation has reached the peak of the early stage of foundation building, and he can break through to the middle stage of foundation building at any time. In this way, it is believed that sacrifice and refining will be easier than before.

Thinking of this, Wang Lin opened his mouth and sprayed out a mouthful of blue cold spiritual energy. As soon as the spiritual energy touched the scabbard, it immediately turned into layers of frost, and wrapped it in the scabbard in the blink of an eye.

Wang Lin pointed with his right hand, and the scabbard slowly turned in the air. A trace of blue light radiated from it, looking quite beautiful.

Wang Lin kept making several blue lights, and each time the blue light hit the scabbard, the scabbard would tremble. Gradually, Wang Lin's hands became faster and faster, and blue lights filled with spiritual power were almost connected into a straight line. The frequency of the scabbard trembling continued to intensify without any pause.

Wang Lin secreted a lot of sweat from his forehead, but as soon as he appeared, he was frozen into ice beads by the cold air around him and fell to the ground. Wang Lin had no time to take care of these things. He stared at the scabbard intently, then quickly shot out a few blue lights, and quickly patted the storage bag. A gourd appeared in his hand. After taking a sip, he continued to sacrifice and refine.

Time passed slowly. After the scabbard continued to tremble for so long, the blue light on its surface flickered and darker. Slowly, a pentagonal pattern emerged from the scabbard.

Seeing this pattern, Wang Lin breathed a sigh of relief and stopped firing blue lights. He slightly adjusted his spiritual power in his body and said to himself: "The cultivation level is nearly five times stronger than before. He used the method Situ Nan told him to force out the formation in the sword sheath with spiritual energy. He created more than five thousand spiritual energy in total. In the end, he was exhausted and had no energy to continue to sacrifice and refine. But now after firing out a thousand spiritual energy, the formation has already appeared. Although his cultivation level has increased a lot, it is still much worse than the Dan-Creating Stage. Situ once said that in the Dan-Creating Stage, only a few spiritual energy is needed to force out the formation."

Taking a deep breath, Wang Lin pinched his right hand and slighted his lower abdomen. He immediately pulled his chest and showed a painful look on his face. His right hand slowly lifted up from his lower abdomen, and then opened his mouth, and a blue cold pill the size of a baby's fist floated out of his mouth.
