You think I have mixed spiritual roots? I became an immortal through a spirit gourd, so what are you

"boom!"

With a loud bang, the head of the Yin Puppet exploded under Zhou Qiang's fire-based magic attack.

"Run! There are more than a dozen more like these puppets in this mine. We can't possibly hold them off!" Zhou Qiang shouted at Chen Huai'an.

"You go first, I'll cover your retreat," Chen Huai'an shouted at Zhou Qiang.

"Alright, senior brother, thank you. When we get back to the surface, I'll definitely treat you to a spiritual feast." Zhou Qiang's magical power was completely exhausted, making it unsuitable for him to stay here. As for the remains of the Yin Puppet, Zhou Qiang didn't want them.

The situation is critical. If he escapes sooner, he has a chance of survival. If he stays in the mine for these spoils, his life will be in danger.

Chen Huai'an didn't have so many concerns. Although he had consumed some of his mana during the mining, he had cultivated the Chaos Five Elements True Technique, and his meridians were already wide, so he recovered his mana much faster than others.

Furthermore, he also wanted to test the strength of this Qi Refining Realm Yin Puppet, so he didn't rush to leave but chose to stay.

Chen Huai'an was no pushover; he wasn't really going to help the other party clean up the mess. What he wanted was the corpse of the Yin Puppet.

Inside the mine, he sensed three Yin puppets nearby. He wanted to test his strength, since he had just broken through to the fifth level of the mid-stage of the Qi Refining Realm. With his current combat power, he was much stronger than before, and it was impossible for a few Qi Refining Realm Yin ghosts to scare him away.

Furthermore, Chen Huai'an did not use his full strength during the battle; he only used wood-based magic. If he had used wood-based and fire-based magic, he could have instantly killed the Yin Puppet without Zhou Qiang having to lift a finger. When traveling, one should always be wary of others, even if one has the intention to harm them.

The remains of the Yin Puppet must be handed over to the sect. If he doesn't kill a few Yin Puppets during his few days in the underground mine, Huang Kunlin and Su Wanying, those inner disciples, will probably cause him trouble again even after he returns to the surface.

"roar!"

No sooner had Zhou Qiang left than another roar rang out, followed by another Yin Puppet rushing out of the mine and pouncing directly at Chen Huai'an.

Now that only Chen Huai'an was in the mine and there was no one else, he had no need to continue to hide his strength. He cast an Earth Spikes spell, and several sharp earth spikes several feet long appeared on the path that the Yin Puppet was bound to take, blocking its way.

Then, he unleashed his vine technique, immediately binding the Yin Puppet at the forefront.

Just as the Yin Puppet was about to break free from Chen Huai'an's vine technique, Chen Huai'an unleashed a fireball, instantly sending the Yin Puppet flying. Chen Huai'an then unleashed another wave of earth spikes, breaking through the Yin Puppet's defenses.

The puppet was pinned to the wall by the earth spike technique, and it was still struggling to get up. Chen Huai'an then unleashed another wave of fireballs, which finally stopped the puppet from moving.

Chen Huai'an realized that killing Yin Kui was not simply a matter of brute force.

Also, attribute clashes don't necessarily mean you can instantly kill this Yin Puppet. The reason he was able to kill this enraged Yin Puppet was because his fireball hit the Yin Puppet's head.

The Yin Puppet's head is its weak point. Even if his earth spike technique pierces through its body, it might not be enough to kill it.

Only by combining Earth Spikes with a Fireball to pierce the opponent's defenses can you easily kill them.

The vine technique is merely used to restrict the opponent's movement, making them a sitting duck.

To kill this Yin Puppet faster, you don't actually need the Vine Technique. Just use the Earth Spike Technique to tear through its defenses, and then use the Fireball Technique to accurately hit the Yin Puppet's head and blow it apart.

The Yin Puppet had just been killed by Chen Huai'an, and before he could even collect his spoils, two more Yin Puppet pounced on him.

At this moment, Chen Huai'an no longer showed the panic he had just displayed.

The Earth Spike spell is cast, forming an earthen wall from the ground to block the opponent from rushing forward. Then, a huge earth spike is condensed and shoots through the opponent's chest defense. Taking advantage of this moment, a fireball spell is cast to smash the opponent's head.

With just one attack, the ferocious Yin Puppet was blasted to death before it could even get close to Chen Huai'an.

It only took Chen Huai'an a few breaths to kill the three Yin Puppets.

When Chen Huai'an arrived at the underground mine, he had heard from Su Wanying and the others that the sect would reward 500 contribution points and 100 low-grade spirit stones for killing a Yin Puppet at the Qi Refining Realm.

Within the Qingyun Sect, the most valuable thing is contribution points. Contribution points can be exchanged for cultivation techniques and can also be used to purchase cultivation resources at low prices. These things are rare and hard to come by.

These Yin puppets at the Qi Refining Realm were all instantly killed when they encountered Chen Huai'an.

Chen Huai'an was planning to pull off a big heist; killing the Yin Puppet would be much faster than mining for spirit stones.

In less than the time it takes to drink a cup of tea, he earned 1500 sect contribution points and 300 low-grade spirit stones. If he were mining in this mine, he wouldn't be able to mine 1800 low-grade spirit stones in the time it takes to drink a cup of tea.

These Yin puppets would be dangerous to other outer disciples, but for Chen Huai'an, they were simply easy prey.

Of course, Chen Huai'an killed the Yin Puppet very quickly, and his mana was also greatly depleted, especially when he was condensing his killing move. He used high-grade spirit stones to restore his mana.

Consuming one high-grade spirit stone is equivalent to 100 low-grade spirit stones. If you don't leave the underground mine and instead choose to use high-grade spirit stones to restore your lost mana, it's not a very worthwhile deal.

If it were to go in and out of the mine, Chen Huai'an would also spend a lot of time. There was absolutely no need to leave just to save a few spirit stones; he could simply stay inside and get to work.

After storing the three Yin puppet corpses in his storage bag, Chen Huai'an continued deeper into the mine.

"Huh, what's going on? The spiritual energy here is even denser than the place we just left." Chen Huai'an went deeper into the mine by more than 100 meters and discovered something: the spiritual energy of heaven and earth in this mine was extremely dense.

Inside this mine, even without using spirit stones to restore his depleted mana, he could quickly restore his depleted mana by directly circulating the Chaos Five Elements True Technique.

The denser the spiritual energy in this mine, the better the contents; there must be treasures inside.

"roar!"

Chen Huai'an ventured another 500 meters, encountering over a dozen Yin Puppets along the way, all of which he easily slew. Suddenly, a low, guttural roar echoed from ahead. This voice was different from the one Chen Huai'an had used to kill Ying Kui; it was deep and suppressed.

"Something's not right. This Yin Puppet is a bit different from the Yin Kui I just killed." Chen Huai'an cast a Qi Observation Technique and found that he couldn't see through the Yin Puppet's cultivation level, which puzzled him.

Previously, even against Foundation Establishment level experts, he could discern their cultivation level using his Qi Observation Technique, but this Yin Puppet before him gave him a dangerous feeling. However, the aura it released was very vague, unlike that of a Foundation Establishment level Yin Puppet.

Chen Huai'an also noticed that the Yin puppets he had killed before all had rather dull eyes, but the Yin puppet in front of him had red eyes and was much larger than the ones he had killed before. "Could it be that this guy has mutated?"
