Time flies by in a hurry, and in a blink of an eye, half a year has passed.

I still give a low-grade Nether Pill to Song Yu every month, tirelessly digging low-grade Nether Ore every day, Song Yu asked me the reason several times, and his reason was that he only needed to dig five hundred low-grade Nether Ore every month, so there was no need to work so hard. My explanation is that you always have to dig early and dig late, maybe you don't want to dig in a month, and there are still enough to recharge, he saw that what I said seemed to make sense, so he also saved a lot of low-level nether ores. I still didn't dare to absorb the netherworld power in the ore, but I had a faint feeling that I was about to break through to the Imp Quadruple Realm.

Occasionally, an ironclad beast would appear in the mine, and we would fight the tooth sacrifice, during which I would also abuse the number and besiege the ironclad beast with them, and try the power of the Tiger Trick by the way, my body and limbs were several times stronger than before, which made me very happy.

Time passed like this, and another half a year passed, and my strength was raised to the fourfold realm of little ghosts, and when I faintly touched the threshold of the fifth, I stopped absorbing the power of the netherworld in the low-level nether ore, so as not to raise my strength too quickly and arouse everyone's suspicions.

Most of the miners were promoted to the sixfold realm of little ghosts, and Song Yu was even promoted to the sevenfold realm of little ghosts. I looked at the mountains of low-grade Netherore in my storage bag, and I was a little hesitant to do it.

It's been a year since I left the human world, and my parents know how worried they must be when they know that I am gone, and how can I return to the human world. Now let alone return to the human world, I can't even do how to get out of this mine. The disciples of the Qingying Sect stationed outside the mine are all the strength of ghost soldiers, and they can kill me in seconds with one finger. You can't beat it, but what if you run away? Ghost soldiers can condense ghost wings, can fly in the air, and can't escape their palms with their foot strength, now they really can't fight, they can't escape, what should I do? I felt infinite despair in my heart, am I really going to be trapped in this mine forever?

This mine seems to be a cage, and we are slaves, squeezing what little value we have left, handing over five hundred low-grade Nether Ores every month, and five hundred low-level Nether Ores outside can be exchanged for fifty low-level Nether Pills. Give us five low-level Netherworld Pills every month, so that we have a glimmer of hope to live, as long as we are promoted to the Ninefold Realm of Little Ghosts, we will have a chance to go out, because reaching the Ninefold Realm of Little Ghosts can become disciples of the Netherworld Sect, every miner will survive with such a little hope, maybe ten years, twenty years, or even a lifetime, and finally die in this dark mine. Thinking of this, the despair in my heart deepened, I must go out, even if it was to risk my life.

"Brother Song, congratulations on reaching the Sevenfold Realm of Little Ghosts, and you are one step closer to your goal in this mine." I arched my hand.

"Little Nine Brothers, don't make fun of me, when I was tricked in, I was not far from the Little Ghost Sevenfold Realm, and it is still far from reaching the Little Ghost Ninefold Realm, and there are a lot of low-level Netherworld Pills needed, hey, there are still nineteen years to go, it's like a year!" Song Yu said.

"Isn't there any other way to get out? Maybe we can figure it out. I asked tentatively.

"It's impossible to break in or sneak away, there is Old Monster Li guarding outside the mine, even if he is not there, there are disciples of the Qingying Sect outside the valley, they are all strong people in the realm of ghost soldiers, as long as we get close to Baizhang, we will be perceived by them, they can kill us if they turn their hands, brother must not have the idea of luck." Song Yu said solemnly.

"Brother Song, the roads in this mine extend in all directions, and there are often ironclad beasts attacking, do you say that if the miner dies inside, the Qingying Sect will send someone to track it down?" I asked.

"Tracking? They don't have that spare time, and if they lose one or two miners, they will send someone to fill the vacancy, or simply leave it alone, unless it hurts the muscles and bones, I remember that when I first came in, there was a miner who was bitten to death by an ironclad beast of the sixfold realm of the little ghost, and you are here to fill his vacancy. Song Yu said.

"Brother Song, I have thought of a way to get out, but I may have to ask you for help." I say.

"Oh? Little Nine Brothers, as long as you have the opportunity to go out, it is my duty to need any help, but it doesn't hurt for you to talk about it. Song Yu said excitedly.

"There are a lot of low-grade netherworld mines stored in this mine, and everyone usually mines not far from the entrance of the cave, if they mine like this, let alone twenty years, I am afraid that they will not be able to dig it in fifty years. I wanted to dig deeper into the mine, digging in one direction and trying to find my way out. Think about it, if you can go out and exchange the low-level Nether Pills we dug for low-level Nether Pills, wouldn't it be easy to reach the Ghost Soldier Realm? I said excitedly.

When Song Yu heard me say this, he was also a little moved.

"Brother Xiaojiu, it's too dangerous for you to go alone, in this way, I will open the way with you, anyway, we have a lot of low-level Netherworld ores in our hands, even if we don't mine, it is enough to make a difference, if there is danger, I can protect you as soon as possible." Song Yu said.

The two of us hit it off, just do it, and dig for three months in a row, and every time it comes to pay the low-grade Nether Ore, I will help him pay it, which also saves him time running around. Old Li at the entrance of the cave saw that the low-grade Netherworld ore that should have been handed over had been handed over, so he didn't ask much. The distance from the other miners to the entrance of the cave is only a quarter of an hour at my current speed, and the distance from where Song Yu and I dug to the entrance of the cave is now three hours.

Another year passed, and we thought we had dug deep enough, but unfortunately we still didn't find our way out, and I felt a little discouraged. Was it the wrong way to do it? Maybe it won't work at all. From where we've dug now, it's getting farther and farther away from the entrance of the cave, and it's been twelve hours since I ran back, and even if we were killed by the monsters, no one would know. The only good news is that I have been promoted to the fivefold realm of little ghosts, and I finally have the power to protect myself in this mine, Song Yu is overjoyed, but he is no longer surprised by my ascension speed.

"Brother Song, we have dug so deep and haven't found a way out yet, is there no way out of this mine at all?" I asked.

"Brother Xiaojiu, don't be in a hurry, we've only been digging for a year, I don't believe it, I can't find an outlet after digging for ten or eight years, even if I don't find an exit, I have to mine here for more than ten years before I have a chance to go out, anyway, I don't lose anything." Song Yu comforted.

Hearing Song Yu's comfort, I felt a little relieved, but I was too anxious. Seeing the low-grade Netherworld ores piled up like a hill in the storage bag, I was eager to go out and find a place where no one was there to absorb and improve my strength. In the course of digging deeper this year, we dug no less low-grade Nether ore than we did near the cave entrance. I stuck my cultivation at the peak of the fivefold realm of the little ghost, and I only need to absorb a trace of netherworld power to improve the realm.
