Forming a Tao root was a very dangerous thing. If one was not careful, one would fail and fail. However, this result was either cutting off the path of cultivation or disappearing into the end. There were no other outcomes.

To condense a Tao root, one needed to absorb and refine heavenly materials and treasures that contained their corresponding properties of spiritual energy. This kind of heavenly materials were called Tao Foundation materials, and each one contained boundless and boundless spiritual energy of the attribute.

In terms of value, every single one of them was comparable to Class 6 Spirit Dans. Not only were they precious, they were also extremely rare.

The higher the grade, the more precious and rare the dao foundation material was, the more boundless and pure the attribute power contained within it.

A low-grade Dao foundation was naturally a low-grade Dao foundation, while a middle-grade Dao foundation was a middle-grade Dao foundation.

If a quasi-Saint was a martial artist with three types of spiritual energy, then he would have two high quality Tao Bases and the third medium quality one. Then, the Tao root he formed would only be medium grade and not high grade.

It was like a wooden bucket. The water it could hold was at most equal to the lowest piece of wood.

Most of the Martial Saints condensed by ordinary Martial Saints were of the medium grade. Only those with low level talent and poor foundations or those with no great destiny or background would choose them.

As for those higher level ones, those with heaven-defying talent and deep lucky chances, or those with quite a strong background, would be able to condense them.

Only the Holy Son of a powerful transcendent Holy Land with deep roots like this would have the chance to condense them.

Absolute quality. Over the past tens of thousands of years, he had never heard of such a thing.

One must be self-aware of the materials needed to form a Dao Foundation and choose to absorb them. Otherwise, one would explode from being unable to withstand the violent energy.

The higher the base level, the stronger the battle prowess, the better the potential, but it is not absolute.

In his previous life, Lingyun had a lot of opportunities, and had painstakingly gathered the three types of Dao foundation materials that he needed. All of them were of the highest quality, and it was unknown how many people were envious of them.

In Lingyun's eyes, this middle-aged man in front of him was clearly someone who did not know his limits. He recklessly tried to refine high grade Dao foundation materials, but in the end, he could not and died.

Looking at this middle-aged man, Ling Yun sighed in his heart. It was all to pursue a higher level of martial arts!

Lingyun recalled the Earth element materials he felt in the cave hall above, if his guess was not wrong.

The person in front of him was at least a quasi-Saint of fire and earth elemental spiritual energy. With two types of spiritual energy, he could be considered quite talented.

Thinking about this, Lingyun's eyes lit up. Even if this arrogant middle-aged man in front of him was just a beginner, he had at least two types of spiritual energy, and his talent was not that weak.

For a foundation material that a martial artist that could barely become a genius to be unable to withstand, it should at least be a medium-grade top quality material or even a high grade one.

If he could obtain it, it would be considered a pretty good harvest and could be given to Lin Xie and the rest in the future.

Even if it was a Holy Land, it was not an easy matter to take out materials with a high Dao foundation.

As for him, his standards were not high. He did not like someone of his level, so the materials he needed to form his Dao Foundation were at least of the highest grade.

Ling Yun's eyes flickered, holding the Heaven-Devouring Divine Light Sword tightly, he connected his mind to the purple ring, preparing to deal with any unexpected situations.

Step forward...

"Bang!" "F * ck!"
