"That's not right. I feel like my real body is circling around here. Why... why can't I see him!!!"
An extremely puzzled expression appeared on the face of the Yin Fire God Puppet. It felt its own body, but it could not see its existence.
At first Ye Li suspected that someone had accidentally found the real body of the Yin Fire God Puppet and carried it on his body while moving. However, after arriving here, he did not even see a single person.
Although there are plants and mushrooms here, Ye Li did not see any wild beasts or monsters, so it is unlikely that the main body of the Yin Fire God Puppet is being moved by some monsters or wild beasts.
Such a situation made the two of them confused, and for a moment Ye Li could not help but stand there in a daze.
After a long while, Ye Li suddenly remembered something, stamped his feet hard, and said, "No, Senior Yin Huo, if your real body was moving near us, we should have discovered it long ago, but now we can't see its existence, which means it is not where we can see it at a glance."
Yin Fire God Puppet was stunned and asked: "Ye Li, you...what do you mean by this?"
Ye Li asked: "Senior Yin Huo, is there any place near us that we can't see at a glance?"
The Yin Fire God Puppet looked around. Although there were trees here to cover the view, the trees and vines were not too dense and basically could not block Ye Li's sight.
“Yes, it’s underground, right? I can sense my body hovering near us, but we can’t see it on the ground.
The only possibility is that it is not actually moving on the ground, but is underground beneath our feet."
The Yin Fire God Puppet shouted loudly.
Ye Li nodded and said, "Yes, that's what I guessed. I think your body may not be on the ground at all, but in the soil underground.
Or rather, it is not in the soil, but there is an underground world in the land beneath our feet, such as a huge cave!!!"
After hearing Ye Li's speculation, Yin Fire God Puppet thought more and more that it made sense, and said: "Yes, you are right. Now that I think about it, I always feel that there is some distance between it and my body. It turns out that this is the reason. It is not on the ground, but underground.
Let’s quickly look for any caves on this island that lead underground!!!”
The Yin Fire God Puppet began to get excited.
Ye Li nodded when he heard that, and then took Xiao Jin to search the island frantically. They also wanted to see if there were any caves around that could lead to the underground.
The huge island made their search difficult. Ye Li searched a large area where the Yin Fire God Puppet felt its body but did not see any caves that could lead to the underground. He then casually cast a spell, hoping that he could dig a path directly underground.
However, after digging for nearly a quarter of an hour and making a huge hole in the ground, he chose to give up this method because the huge hole did not lead to the underground. This showed that the underground cave was extremely deep and it would be difficult for Ye Li to find it by digging from the ground.
Moreover, the rocks underground will become harder and harder as the depth increases. Even if Ye Li is strong and powerful, it is impossible for him to dig deep underground endlessly.
After thinking about it, Ye Li could only expand his search range and began to look for caves leading to the underground deep in the island.
After spending a whole day, Ye Li found quite a few caves, but none of them led deep underground. It was not until the morning of the next day that he finally found a huge cave that could go deep underground near the edge of the island.
At this time, they were already quite far away from the Yin Fire God Puppet's main body. After a day passed, the connection between the Yin Fire God Puppet and it became a little weaker.
"This should lead to the depths of the ground. Let's go in and take a look!!!"
After Ye Li said something to the Yin Fire Divine Puppet, he dived into the cave and began to move deep underground.
As he lit up the rune crystal lamp and began to go deeper into the earth, the yin and fire energy around him began to become more and more dense.
In particular, the Yin force is extremely strong, and the deeper you go underground, the higher the concentration becomes.
After going dozens of meters deep underground, the Yin spiritual energy has begun to become viscous. A talisman master with slightly weaker strength cannot stay here for a long time.
These extremely rich Yin spiritual energies have already possessed a strong corrosive ability, which can erode the spiritual essence and blood vitality of the talisman master.
Ye Li has already activated the secret method of Casting Yin, integrating himself into the surrounding environment. In this way, he is like a drop of water flowing into a river and is not affected at all.
As they went deeper, the Yin Fire God Puppet's perception of its own body began to gradually increase, which also showed that the direction they were searching was correct.
"Why is there such a strong Yin power on this island? This is too strange."
Ye Li said with a frown.
Tun Ri said: "What's so strange about this? Yin and Yang Qi can exist anywhere in the world. Some places are naturally suitable for gathering Yin force, so Yin force is strong. Some places are suitable for gathering Yang force, so Yang force is strong.
As for fire energy, there is plenty of it underground. When combined with Yin energy, it becomes Yin fire energy. When combined with Yang energy, it becomes Yang energy. These are all very normal things.”
Ye Li heard this and said, "Could it be that this is where the Yin Xing force gathers?"
Tunri nodded and said, "Well, most of them are Yin Eyes, which absorb the Yin spirit energy from all directions."
After hearing Tunri's words, Ye Li's doubts disappeared for the most part, but he still couldn't understand why the Yin Fire God Puppet's body moved.
The Yin Fire God Puppet himself couldn't figure it out, so they could only continue to go deeper into the ground.
After walking for almost half a day, Ye Li estimated that he had gone more than half a mile underground. The surrounding caves showed no signs of shrinking, but instead became larger and larger.
Under the entire island is a huge underground world. The rocks are filled with crystals full of yin spiritual energy, and it looks pitch black.
These black crystals are not casting materials, but just ordinary crystals that grow in places where Yin spiritual energy gathers.
As Ye Li went deeper, the air around him became extremely stuffy and the pressure around him was also quite huge, but Ye Li was strong and was not too affected.
Soon, the fire-type spiritual energy around began to become thicker, and the strong Yin-type spiritual energy began to blend with the fire-type spiritual energy, and gradually Yin fire appeared in Ye Li's vision.
