A glittering purple flickered, bringing a glimmer of light to the otherwise pitch-black crater. With this light, Kong Fang cautiously looked at the most core of this suspected Yuanshi pit.

There were dark rocks on all sides, adding a bit of gloomy color under the purple light, but Kong Fang's eyes were staring straight at a thick and bulging stone pillar in the center of the pit.

In the core of the empty Yuanshi pit, there is no Yuan liquid in Kong Fang's imagination, but there is something unusual on the bulging stone pillar.

It was a purple rune paper, the size of a palm of the hand, and it was clinging to the top of the stone pillar. The sparkling purple glow emanated from it.

"It's gathering Heaven and Earth Yuan Force!" Suddenly, the light in Kong Fang's eyes fluctuated violently. What did he find? The rune paper in front of him, which was exuding purple light, was actually condensing the Heaven and Earth Yuan Force in all directions at an extremely terrifying speed!

"This ...... What is this?" Kong Fang was shocked, a little speechless. Even in Shen Tu Lie's memory, he couldn't find any information about the rune paper in front of him. I hadn't even heard of such a rich Heaven and Earth Yuan Force being able to gather just by relying on a single rune paper. This method is miraculous.

"Who pasted this rune paper here?" A somewhat unbelievable thought suddenly popped up from Kong Fang's mind, "This Yuanshi pit is not natural at all, but all of it is created by this rune paper!"

Kong Fang was shocked. Because with his powerful soul perception ability, he suddenly found that this purple talisman was like a robber, forcibly extracting the Heaven and Earth Yuan Force in all directions, and the Heaven and Earth Yuan Power extracted by the Purple Mansion was hidden deep in the ground. Therefore, while extracting the Yuan Power of Heaven and Earth, it will also bring a lot of Yin and Evil Qi over, and before he goes deep into this place, even Kong Fang didn't notice it.

"The man-made Yuanshi Pit, it turns out that the Yuanshi vein can still be generated like this. Kong Fang was shocked. According to the degree of the Purple Fu's forcible condensation of the Yuan Power of Heaven and Earth, in tens of thousands of years, it may really be able to gradually evolve into a Yuan Shi vein.

"But why don't you have a trace of Yuan Liquid?" Kong Fang frowned and wondered.

Although the Yuanshi pit in front of him is man-made, because of the purple rune, it is no worse than those real Yuanshi pits, and even the speed of condensing the Yuan Force of Heaven and Earth is farther than it. It stands to reason that there will be a presence of Yuan Liquid in this kind of place, and there may even be more than one or two drops, however......

His gaze swept over this empty pit one by one again, Kong Fang frowned, not to mention the Yuan Liquid, even the roughest Yuan Stone rough embryo here.

It is important to know that although the Yuanshi Pit is not a Yuanshi vein with countless Yuanshi, but in the core of the Yuanshi Cave, due to the perennial strong power of heaven and earth, some Yuanshi rough embryos are still born. The so-called rough embryo of the yuan stone is a stone that contains some yuan power, but it is not very pure, and the amount is not very much. This kind of raw stone rough embryo is much worse than the real yuan stone. But even so, it's a pretty good thing.

"Could it be that there is something else hidden here?" the light flashed in Kong Fang's eyes. The purple talisman that can forcibly condense the Yuan Force of Heaven and Earth, the man-made Yuan Stone Pit, and the pit that is empty around it without any Yuan Liquid and Yuan Stone Rough Embryo, all of them are connected in series, as if an extremely obscure thing was displayed in front of Kong Fang in such a grand manner.

"The temperature is dropping all around. Suddenly, Kong Fang's eyes froze, and in his perception, with the passage of time, the temperature in this pit had been dropping. This difference in temperature was not felt much at first, but now that most of the quarter of an hour had passed, even Kong Fang felt a little cold.

"That's ...... Cold Snap!" In the glittering purple light around the Yuanshi Pit, there was already a faint blue light at some point. Kong Fang stared straight at the ground not far from him, and the wisps of faint blue gas that continued to seep up from under the ground. It is with the penetration of these gases that the temperature around them slowly becomes cold.

"When these gases condense to a certain extent, it will be when the cold snap in the Yuanshi pit will erupt again. Kong Fang secretly calculated in his heart that at this time, most of the quarter of an hour had passed since the last cold snap erupted, and there was still about half an hour left, and these cold qi would condense into a cold snap and explode again. And before that, he must leave the Yuanshi pit first. Otherwise, with the location where Kong Fang was at this time, when the cold snap broke out, he really couldn't even run.

"It's time to leave. Kong Fang whispered. At this time, he was at the very core of the Yuanshi Pit, and he had to leave one step earlier. Otherwise, it's very dangerous.

"However......" The light in his eyes flickered, and Kong Fang did not leave immediately, but instead fell on the purple talisman attached to the stone pillar.

"A rune paper that can forcibly condense the Yuan Force of Heaven and Earth. Kong Fang muttered to himself, his heart quite moved. Although he didn't know what else the mysterious rune paper of the Dao Dao was, the mere ability to forcibly extract the Heaven and Earth Yuan Force from the ground was enough to make its value precious.

In Kong Fang's opinion, even a pool of Yuan liquid is far inferior to this rune paper, and even the legendary Yuan Essence that can only be born in the Yuan Stone Vein is not as precious as it. After all, the first two are one-time consumables, but this purple talisman can continuously extract the power of heaven and earth.

Kong Fang knew very well that such a precious purple rune, let alone himself, even a martial artist of the Transformation God Realm would be crazy when he saw it. And at the moment, this Purple Mansion is still ownerless, and in the face of this temptation, who can really resist it.

"Perhaps only the owner of the original talisman paper can do it. Kong Fang muttered to himself. But he's not the kind of power that can do anything. He is just a small Spirit Silence Realm martial artist, and this purple talisman is undoubtedly a great creation. With it, do you still need to stay in this Yuan Stone Pit? Are you still afraid that your Yuan Power will not be enough? And your own cultivation speed can skyrocket to another level.

The richness of the Heaven and Earth Yuan Force here is almost twice as strong as the Heaven and Earth Yuan Force in the outside world. Such a rich Heaven and Earth Yuan Force is even much better than some Blessed Land Cave Heavens that are occupied by powerful forces. With this kind of benefit, it is almost impossible for Kong Fang's cultivation speed to slow down a little.

"Die the bold and starve the cowardly!" Suddenly, a glint flashed in Kong Fang's eyes, and the whole person jumped up and stretched out his hand towards the purple talisman attached to the stone pillar.
