Serpent Ancestor

Three days passed in a flash.

During this time, Xu Hei dug out fifty barrels of oil from underground. This layer of oil was nearly exhausted, so he had to continue digging deeper.

The deeper he went, the more dangerous it became. Xu Hei tried sending a puppet down the well, but it was soon pulled into the abyss by a tremendous force.

After three days, the butcher's body was completely blackened, severely contaminated.

Xu Hei took a Detoxification Pill and used the Demon God Cauldron to refine it, preventing the contamination from worsening.

The black smoke inside the Demon God Cauldron had also gathered to a certain concentration.

"Let's see if the Ten Thousand Poison Gourd can absorb it."

With a thought, Xu Hei summoned the Ten Thousand Poison Gourd, guiding the black smoke from the Demon God Cauldron into the gourd.

Inside the Ten Thousand Poison Gourd, there was originally a wisp of poisonous smoke, taken from Bonan.

When this wisp of poisonous smoke came into contact with the black smoke, it rapidly expanded and merged with it, turning into a deep purple color.

"Oh?"

Xu Hei raised an eyebrow.

He hadn't expected the poisonous smoke he collected earlier to actively merge with the black smoke. This suggested that the Sea God Sect's poison was refined using heavy oil? Since they originated from the same source, they didn't repel each other!

Xu Hei's eyes flickered. He tapped the gourd, and a wisp of purple smoke flew out, transforming into a thin thread.

Originally, Xu Hei couldn't control this purple smoke and it was easy to harm his own people. But ever since it merged with the black smoke, his control over it had greatly increased.

"Go!"

Xu Hei pointed forward, and the thin thread rose into the air, randomly sweeping across the air and striking the stone wall, corroding small pits into it.

This poisonous mist thread wasn't very aggressive towards objects, but it was extremely polluting, posing a devastating threat to living beings.

Xu Hei seriously doubted that even Elemental Infant cultivators would want to be contaminated by this poison.

"Return!"

With a thought, Xu Hei recalled the thread back into the gourd.

"The poison from Bonan, combined with the fusion of heavy oil black smoke, is yet another powerful weapon for me!" Xu Hei thought to himself.

Next, Xu Hei continued to channel the black smoke from the Demon God Cauldron into the Ten Thousand Poison Gourd.

This was a delicate task, requiring meticulous control over both magical treasures. It took Xu Hei two days to complete, leaving him exhausted.

After a brief rest, he was about to dig for more oil.

Suddenly, Xu Hei's expression shifted as he looked toward the cave entrance.

The cave was blocked, but he could clearly sense that people had come down, and not just one.

"More slaves... Since that person doesn't dare to come down personally, I'll give you a push!"

Xu Hei's eyes turned cold. He tossed out some Spirit Stones and flicked his fingers, causing the stones to explode and release a surge of Spiritual Qi.

The people outside, upon approaching, immediately felt the long-lost surge of Spiritual Qi. But they didn't dare to absorb it, their faces changing dramatically as they retreated cautiously.

How could Spiritual Qi appear out of nowhere in an oil well?

This oil well had been deserted for a week because people had died here. Was it haunted?

No one dared to approach, and they all retreated. Two bold individuals, tempted by greed, wanted to move forward to absorb the Qi, but with everyone else leaving, they stood out and had to retreat as well.

Not long after, about an hour later, a figure clad in a black robe descended from the well.

This person had a gloomy expression, slightly plump, and was protected by a golden Talisman that temporarily shielded him from the heavy oil's contamination. He also used an Invisibility Talisman, fully armed, as he entered the oil well.

This person was Ma Fugui, who had drawn lots to investigate the anomaly.

He moved swiftly, quickly reaching the source of the Spiritual Qi eruption, and looked around, indeed finding faint traces of a Formation on the stone wall.

"So it's hidden here!"

Ma Fugui's eyes turned cold. He retreated slightly and summoned five Formation flags, placing them around the Formation.

Then, with a change of hand gestures, the Five Elemental Formation flags connected, outlining complex patterns that intertwined with the Formation left by Xu Hei.

In just a few breaths, Ma Fugui successfully hijacked the illusion Formation!

Stealing Formations was Ma Fugui's specialty, allowing him to do so without the other party noticing.

In fact, Xu Hei hadn't sensed the loss of the Formation, nor did he notice anyone coming down.

But from an hour ago, he had been highly focused, all his attention on the cave entrance.

His Black Dragon Sword, Blood Killing Sword Formation, Ten Thousand Poison Gourd, and even the Minor Annihilation Talisman he acquired at auction were all aimed forward, ready to unleash a deadly strike at any moment.

He knew that the person behind the scenes might come down without him sensing it, possibly sneaking into the cave silently.

Having suffered once at the hands of Hou Siping, Xu Hei wouldn't make the same mistake twice. No matter what kind of demon or monster it was, as long as his firepower was strong enough, he'd turn them to dust.

"This Formation doesn't seem like Hou Siping's work..."

Ma Fugui squinted his eyes, and with a bit of thought, he immediately guessed that Hou Siping had been harmed. The other party might have deliberately released Spiritual Qi to lure him down and then kill him.

This made him extremely cautious.

"Just an early Core Formation stage, even if you suppress your cultivation, so what? Who hasn't hidden their strength?"

Ma Fugui sneered. On the surface, he was at the mid-stage Core Formation, but in reality, he had late-stage cultivation, and with a magical treasure, he could rival someone at the Great Perfection of the Core Formation stage.

However, he was always cautious. To be safe, he took out a lamp.

This lamp was called the Seven Star Lamp, using the soul as oil, it could preserve his soul from destruction. Even if he died here, he could be resurrected within the Seven Star Lamp, at the cost of burning his soul.

The Seven Star Lamp lit up, rising with the wind, floating to the well entrance.

After doing all this, Ma Fugui's figure flashed, rushing into the illusion Formation, holding a string of ancient beads.

"Kill!"

Xu Hei's eyes focused. At the moment the disturbance appeared in front, the Black Dragon Sword instantly thrust out. Simultaneously, a thin line shot out from the Ten Thousand Poison Gourd, directly forward, and six Blood Killing Swords unsheathed simultaneously.

He also threw out a Minor Annihilation Talisman, ready to detonate!

No matter who came down, daring to intrude into his Cave Dwelling, killing them was the simplest solution.

Xu Hei hadn't considered capturing them alive, as the risk was too great. He didn't want to be played with again by someone like Hou Siping. Killing was the safest option.

Ma Fugui had just stepped into the cave, the string of beads in his hand not yet activated, when a massive wave of attacks hit him.

This was an attack Xu Hei had been preparing for a long time. Normally, he wouldn't be able to unleash so many magical treasures in an instant. But after meticulously preparing for an hour, it had become a Formation, revealing all his trump cards, killing anyone who dared to block his path!

Xu Hei would no longer underestimate anyone, even if it was just a small fry, he'd turn them to dust!

"Poof!"

Ma Fugui was first pierced by the six Blood Killing Swords, breaking through his outer defenses, then the Black Dragon Sword shattered his protective golden light.

The ancient beads in his hand had just been raised when they were pierced by the thin line from the Ten Thousand Poison Gourd, directly stabbing into his body, the poison penetrating him.

And with the Minor Annihilation Talisman about to hit, Ma Fugui's face changed dramatically, his pupils contracting to a point.
