C505

However, it was not for free. Thinking about the price, Ling Yun felt his teeth ache.

'F * ck, what do you take him for … ' Cultivation Method Martial Skill Library?

One low-grade earth-step spear martial skill and two Universe Rings. These were the costs. After a round of bargaining, they were obtained.

Otherwise, Qin Feng, who was asking for an exorbitant price, would directly ask for a Heaven Ranked lightning spear technique …

He had even taken a fancy to Ling Yun's [Violet Firmament Divine Thunder Hand]!

At this moment, Ling Yun and the other two had their eyes wide open as they looked at the Heaven-Devouring Saint Light Sword and the large ghost blade in Ling Yun's hands.

This was already the third spiritual item the Heaven-Devouring Sacred Light Sword had devoured besides its original large sword. The Heaven-Devouring Sacred Light Sword had broken through to the Second Order as it wished, and was currently charging towards the peak of the Second Order.

The material quality of this ghost head blade was much better than the other spiritual tools he had absorbed earlier. Lingyun could tell from this blade that there was a level six artifact forging material, Stellar Steel, that was used to refine a saint artifact.

So, absorbing the spiritual energy was very troublesome. With the assistance of Lingyun's spiritual energy, the Heaven Swallowing Holy Sword also released the golden Holy Light Flame to help. After refining for nearly a quarter of an hour, the light on the ghost blade only dimmed a little.

Ding!

With a clanging sound, the black Devouring Power and the golden Sacred Flame on the Heaven Swallowing Holy Sword were restrained.

"What's going on?" Ling Er saw this and quickly asked, a hint of worry in her eyes.

"Seems to be so... I'm full! " Ling Yun said speechlessly.

There was nothing he could do about it. The spirit of the Heaven Swallowing Holy Light Sword was still weak, so he could only guess.

"Uh, full?" The corners of Ling'er and Qin Feng's mouths twitched. This Heaven-Devouring Divine Light Sword is truly willful …

The corner of Ling Yun's mouth twitched as he kept the remaining spirit artifacts into the Violet Ring.

"Oh right, I found a door over there, but I can't open it no matter how hard I try!" Qin Feng suddenly smacked his head as he spoke.

"Door?" Ling Yun and Ling'er were stunned. Could it be that the real treasure was hidden there?

Thinking about this, Ling Yun quickly asked, "Where is it?" Bring us there quickly! "

Right now, he was filled with anticipation for those treasures. After all, he had to feed three big stomach kings all by himself …

Qin Feng nodded his head. Lightning flashed under his feet and silver-white lightning Spiritual Energy circulated. A faint buzzing sound could be heard as he turned around and rushed out of the hall.

Ling Yun and Ling'er looked at each other for a moment before quickly catching up.

After exiting the great hall, they passed through several rooms that were in a mess and arrived at a long corridor. Outside of the corridor, there were numerous ancient trees. The air was filled with an ancient aura.

This hall was extremely large and it took up about a quarter of the mountain's area. Earlier, Ling'er and Qin Feng had only searched a portion of it before being drawn back by the battle within the hall.

The three of them were extremely fast. After three minutes of traveling, Qin Feng, who was at the forefront, finally slowed down.

In front of him was a greyish white mountain wall.

Finally, Qin Feng stopped in front of the mountain rampart.

"It's here!" Qin Feng pointed at the mountain wall ahead.

Ling Yun and Ling'er stared in shock, their eyes filled with astonishment. There was indeed a gigantic stone door here.

However, the stone door seemed to be inlaid into the mountain wall, and its color was the same as well. If one did not pay attention, they would think that it was a part of the mountain wall.

Ling'er probed with her divine sense, and the surprise in her eyes became even more intense. This stone door could actually hide from divine sense, and it was impossible to tell if it was real or fake.

If one did not arrive in person and did not take a closer look, it would be impossible to discover.
