Soon, the Naga disappeared completely.

Huang Yi turned his head and locked his gaze on a spire building on the east side of the castle. The lab that the Eye of Time saw was in the basement of the spire.

He immediately flapped the wings of freedom behind him, used the active effect, entered a state of absolute invisibility, jumped from the window, and flew straight towards the spire building.

It didn't take long for him to fly over the building, land on a balcony, and get through the window.

The building had also been eroded by time, with a barren interior and cracks in the walls, through which a few tenacious vines and plants tangle to meet the light outside.

Huang Yi came directly to a corner on the east side of the building hall, reached out and pressed a brick in the lower right corner. It was a mechanism, and in the image seen by the Eye of Time, the Naga pressed the brick, and then revealed an entrance to the basement.

Soon, the floor shook slightly, and several floor tiles parted on either side, revealing an entrance.

The entrance was connected to a spiral staircase, and from the top of it looked down, and the staircase circled and circled, and the bottom was shrouded in darkness, I don't know how deep, as if it led to the depths of hell.

Huang Yi got into that entrance, walked down step by step, and fell into the darkness.

The location of this basement is very secretive, and even if most adventurers can come to the Scarlet Castle, it will be difficult to find this mechanism. Those Naga should have just arrived in the Scarlet Castle, but it must have taken a lot of effort to find this underground laboratory.

Huang Yi relied on his dark vision, walking down step by step, the staircase seemed to have no end, and after walking down for a long time, it was still bottomless. The only thing left in the air was his lonely footsteps, echoing over and over again.

"Da Da Da!" At this moment, a rush of footsteps suddenly came up from the bottom of the stairs, as if someone was going upstairs!

Huang Yi's heart froze, and he hurriedly resorted to absolute stealth and disappeared into the air.

Soon, several figures came up downstairs, all dressed in alchemist robes. But their figures were translucent, just like the handmaidens they had seen in the church before, just remnants of history.

These afterimages were talking while going upstairs, and their voices were hazy, echoing from the depths of ancient history.

"How many times have I said that! When alchemy is pharmaceutical, don't put realgar and replace it with other raw materials, Lord Bloodhoof hates realgar the most! An older alchemist scolded the rest of the alchemists.

Those alchemists hurriedly lowered their heads and admitted their mistakes again and again.

Soon, the afterimages of these alchemists directly penetrated Huang Yi and walked to the top of the stairs, and the voices of their conversation became more and more hazy, and finally disappeared.

Huang Yi retracted his gaze and continued to walk down.

This blood-colored castle is simply haunted, and the remnants of history can be seen almost everywhere. When people come to this castle, they think it is haunted, and they may not even have the courage to explore.

After walking down for a long time, Huang Yi finally walked the long staircase and came to the deepest basement.

Huang Yi relied on his dark vision and looked at the surrounding scene.

This is a huge laboratory, which is densely packed with all kinds of sophisticated instruments. But it seems that it has been abandoned for a long time, and many of the instruments have been covered with dust, and some have even fallen to the ground, turned into parts, and completely destroyed.

Huang Yi followed the route seen by the Eye of Time and walked directly to the eastern area of the laboratory. He walked through the instruments and walked without a trace in the darkness, as if he had become one with the darkness.

Finally, a moving instrument appeared in front of me, standing out among the dusty instruments. There was a bottle at each end of this instrument, which was the Divine Crystal Bottle and the Demon Bottle that Huang Yi's Eye of Time had seen.

That mysterious liquid is contained in that divine crystal bottle!

But the next moment, Huang Yi's footsteps stopped abruptly, and his eyes were locked on a position next to the instrument.

In that hidden dark corner, a hazy figure faintly revealed, the upper body of that figure was in human form, and the lower body was a snake tail, it was a Naga!

It seems that the group of Nagas was also very cautious, and did not leave the Scarlet Castle all, but still arranged for those who stayed behind.

This also further reflects that the drop of liquid in the Divine Crystal Bottle is indeed very precious, otherwise it would be impossible to send someone to stay by and monitor it in real time.

The momentum of this Naga is far less powerful than that Red-scaled Naga, and it feels like it should be an intermediate Heavenly Domain powerhouse that does not exceed level 250.

With an enemy of this level, Huang Yi can easily deal with it. However, he must fight quickly, preferably before the opponent has time to react. Otherwise, the other party may use a special way to spread the news of Huang Yi's invasion of this basement, or even to the ears of the red-scaled old man, and then Huang Yi will be in great trouble.

Huang Yi thought about it for a while, and quickly made a rough battle plan.

He immediately took out the God-Killing Fury from the storage ring, directly flapped the wings of freedom, and rushed towards the Naga invisibly!

"God said there would be light, and there was light!" As he rushed, he quickly recited the words and spirit scriptures!

In such a pitch-black environment, the effect of Huang Yi's words and spirit scriptures turned into a dazzling high-intensity flash!

Suddenly, the entire underground was white and irradiated with high intensity!

That Naga had been in the dark all the time, and his eyes were used to it, but now he was suddenly exposed to this kind of strong light, and he was blinded all of a sudden, and the whole person was stunned in place.

At that moment, Huang Yi suddenly appeared behind him, and the god-killing wrath slashed through a swift light and slammed into its neck!

"Poof!" A sound of flesh cutting sounded, and the Naga's head flew straight out, slammed into a device, catapulted to the ground, and rolled several times before finally stopping.

His expression was still sluggish at the moment just now, and before he could react from that strong light, he was instantly killed by Huang Yi.

At this moment, the headless body of the Naga fell weakly, and blood gushed out from the broken wound in his neck, soaking a large area of the ground in an instant.

Huang Yi exhaled a long breath, put away his god-killing anger, and came to the instrument.

His gaze was locked on the Divine Crystal Bottle, locked on the small drop of liquid inside! (To be continued.) )
