Chapter 574 Searching for the Mysterious Ruins (Continued)

In the dark and damp underground passage, a figure flew past and disappeared at the end of the passage in an instant.

Yu Guihai ran wildly, feeling a sense of coolness like subway surfing in his heart.

He soon came to a huge canyon, jumped down without hesitation, and then entered a cave at the bottom of the canyon.

At the end of the cave is the fourth floor of Guitou Mountain Cave, which is an endless underground space with no edge at a glance, and the ground disappears in the black mist.

The yin energy here is extremely strong, not much worse than that of Lianyin Peak.

Yu Guihai came here to find the ghost king, and it must be the ghost ghost king.

The so-called ghost is a kind of ghost. It is born with a sense of seclusion, good at traveling through the void, and its body is ethereal. It can avoid spells and physical attacks and is very difficult to deal with.

But this ghost ghost king is the second main material for his refining ghost shuttle.

In addition, he also needs to look for other ghost kings, such as the Five Fire Ghost Banner.

He now has three of the Five Fire Ghost Banners, Yin Fire, Corpse Fire, and Ghost Fire, but still lacks two of the Ghost Fire and Ghost Fire.

For these two, Yu Guihai no longer has any hope of finding the finished treasure, because there is no clue at all.

What happened in Yunmiao Mountain a thousand years ago that led to the decline of Lianyin Peak? Where did the predecessors of Lianyin Peak go? Where did the skills and treasures lose?

If these questions can be answered, he may be able to find the whereabouts of the remaining two Ghost Banners.

However, he asked the old ancestor Wu Jin, but did not get a reply. The old ancestor Wu Jin was very secretive about this and refused to reveal a word, and warned him not to delve into the matter.

Therefore, Yu Guihai prepared to refine the remaining two magic weapons by himself.

Now, he already has a white bone staff, and he still needs a banner face and the corresponding ghost king to refine the fourth Ghost Banner.

Yu Guihai stood quietly in the same place, letting go of his mind. The black fog around him contained this powerful Yin Qi and some mysterious power, which could actually block his mind from exploring, so that his mind could only explore within a range of 10,000 meters.

After a moment, he retracted his mind and frowned slightly. There were many ghosts around, but none of them were at the level of ghost kings.

It seems that he was really lucky to meet the corpse wolf ghost king last time.

Yu Guihai thought about it, and his mind moved. Three figures suddenly flew out of his body. They were the two ghost king clones of water and gold, and the ghost clone of fire, which ranked at the peak of spirit ghosts.

Then, a red little man emerged from his shoulder. It was Wu Hong. Its aura was floating, which was stronger than the fire ghost, but it did not reach the level of ghost king.

In fact, when Yu Guihai was promoted to Yuantai, Wu Hong could be upgraded to ghost king. But it needed to devour a large number of ghosts to be promoted, and it had not absorbed enough.

This time, Yu Guihai released it to let it devour more ghosts, so as to gain enough accumulation and break through the ghost king level in one fell swoop.

"Go!"

Yu Guihai waved his hand forward fiercely, and the four ghosts each chose a direction to fly away, leaving a series of ghost cries and wolf howls along the way.

There are no strong ghosts around, even the weakest fire ghost can be crushed, so there is no need to worry about safety.

What Yu Guihai is worried about is whether he can find a suitable ghost. Even if it is not a ghost king, as long as the attribute is right, it can be cultivated and used later.

Yu Guihai walked quickly, and the four ghosts swept everything in front of him. All the ghosts along the way were devoured one by one, and all the Yin attribute spiritual medicines and spiritual materials encountered were swept away.

After walking for half a day, Yu Guihai swept the area of ​​hundreds of miles around the entrance. The four ghosts devoured countless ghosts, and the two ghost kings were fine.

The Fire Ghost and Wu Hong had already devoured enough ghosts and were full. As long as they digested these, and there was a suitable opportunity, they could try to break through the Ghost King.

"Master, I can be promoted after digesting them."

Wu Hong flew back with a happy face, his belly bulging high, as if he was pregnant for ten months, which was very funny.

"Well, you go back. Take good care of yourself, and I will promote you when you go back." Yu Guihai said lightly.

Wu Hong flew back to the Yin Shen Lantern happily.

As for the Fire Ghost, if it wants to be promoted to the Ghost King, it needs some treasures with fire attributes. It cannot be promoted by swallowing ghosts alone.

Yu Guihai was worried that it would have an accident, so he took it away directly, leaving only the two Ghost King clones wandering outside.

He had already explored the land near the entrance. If he wanted to continue to go out, the land was too large, so he could only choose one direction, and could not cover everything as before.

Yu Guihai sensed it a little and chose a direction. In the distance here was a hilly area with undulating terrain. The terrain was complex and it was most likely to hide powerful ghosts.

He ran all the way and soon crossed hundreds of miles to the edge of an underground mountain range. Looking out, he could see low hills with shadows in the black fog.

On the nearby mountains, you can see strange rocks standing in a forest, like ghosts. The ground was barren, and occasionally there was a plant, all of which were precious Yin-attributed spiritual herbs. Ordinary plants cannot grow in such a strong Yin environment.

Yu Guihai quickly flew up and flew towards the depths of the hills. On his left and right, the two ghost king clones swept over and expanded the distance of exploration.

As he expected, the ghosts in the mountains were more dense, and there were many kinds of spiritual herbs and materials.

Suddenly, Yu Guihai's face changed slightly, and he moved and flew towards the position of the water ghost king.

Not long after, he came to a valley, where the Water Ghost King was lurking in a black fog, with his huge eyeballs quietly looking down.

The valley was filled with strange yellow smoke, which was extremely thick, like a dust fog formed by fine sand.

Waves of shouting and killing came from the yellow smoke, with swords clashing, people neighing and horses shouting, as if two armies were fighting each other, fiercely.

Yu Guihai's heart moved. There was indeed a strong ghost king in the smoke below, but there was a special restriction here, which was very powerful, and there was a faint threat.

He felt that if he fell into it, he would also be affected by this unknown formation.

However, since he was outside, he was not afraid.

He observed a little and found that this formation was completely arranged according to the terrain of the valley, and it was easy to weaken or even destroy it from the outside!

Thinking of this, he raised his fist and punched it suddenly, smashing it down.

Rumble~~~

A thunderclap sounded out of nowhere, and a huge golden fist shadow as big as a house smashed towards the valley, like a falling meteor, unstoppable.

Whoosh~~~

A gust of cold wind blew, and the valley below suddenly became quiet, and the sound of fighting disappeared instantly.

The yellow smoke rolled into a huge armored skeleton, with scarlet eyes staring at the sky. As soon as the skeleton appeared, it swung a giant knife dozens of meters long in its hand and slashed at the golden fist shadow.

Crack~~~

The void exploded, and the giant knife exploded directly the moment it touched, turning into countless yellow smoke and disappearing in mid-air.

The golden fist shadow was almost unaffected, and it slammed down without stopping!

After a period of shaking, the yellow smoke in the valley was swept away by the fierce impact, revealing the true face of the valley underground.

Under the valley, there was a ruin of a city built of yellow stone, and a layer of imperceptible light yellow light shield protected it from destruction under the fist shadow.
