First of all, in the same realm, there are two cultivators with similar martial skills, one of them is a Heavenly Grade Dao Base, and the other is a Spiritual Grade Dao Base.

If the two of them compete and compete, it must be the spiritual grade Dao base person who crushes the heavenly grade Dao base.

Secondly, and more importantly, the quality of the Dao Foundation is related to future cultivation achievements.

Don't talk about it far away, let's talk about the Yudan realm after building the foundation realm.

In the territory of the Jiedan, the Dao Foundation will transform into the Dao Dan, and the Dao Dan also has four grades: the Human Yuan Golden Pill, the Earth Yuan Divine Pill, the Tianyuan Great Dan and the Lingyuan Immortal Pill.

If Su Luo wants to form the strongest Lingyuan Immortal Pill in the Formation Pill Realm, he must build a Spirit Grade Dao Foundation in the Foundation Building Realm!

This is a prerequisite!

You can see it from here.

Each realm of cultivation is not absolutely independent, but is interrelated.

The twelfth layer of the Qi Refining Realm affects the spiritual product Dao foundation of the Foundation Building Realm, and the spiritual product Dao foundation of the Foundation Building Realm affects the Spirit Yuan Immortal Pill of the Jie Dan Realm.

It is impossible to say that a certain cultivator is in the Qi Refining Realm, and if he suddenly cultivates seriously in the Foundation Building Realm, he can become a strong person overnight.

That's unrealistic.

Only when every realm is cultivated in a down-to-earth manner and strives for perfection can we embark on the path of "being the strongest".

Therefore, the spiritual product Dao foundation, Su Luo must be built!

"It's just...... Precious foundation-building things are already rare, especially foundation-building things that can assist in building spiritual quality Dao foundations, so it is even more rare!"

Thinking of this, Su Luo smiled bitterly.

If it is said that he finds a wind attribute spirit object, the difficulty of using it to cultivate the wind mark is one.

Then, the difficulty of finding a foundation building thing that can build a spiritual quality Dao foundation has exceeded at least one hundred.

"It seems that I still have to stay in the Qi Refining Realm for a while, and there are too few things suitable for me to build a foundation...... It is better to lack than to overuse, only if I can build a spiritual quality Dao foundation, I will choose to break through to the foundation building realm. ”

Su Luo secretly planned.

Next, he continued to think about how to find the right foundation for him.

"First explore all the famous rivers and mountains in China?"

Su Luo muttered to himself.

"Many heaven and earth spiritual objects can be used as foundation building things, such as the earth fire buried deep in the center of the earth, the Xuantian polar ice on the 10,000-year-old snow mountain, and the innate water beads in the lake...... These heaven and earth spiritual objects are hidden in the famous mountains and rivers of China, and they are also very good foundation-building things. ”

However, immediately, Su Luo shook his head again.

"These spiritual objects, at most, can assist cultivators in building a Heavenly Grade Dao Foundation, a Spiritual Grade Dao Foundation, it should be impossible. ”

"So...... The ultimate spiritual objects bred in the famous mountains and rivers can only build heavenly products, but my requirements are spiritual products...... Obviously, the path of exploring famous mountains and rivers is not very efficient for me...... Wait!"

Suddenly, a sharp light flashed in Su Luo's eyes, and he thought of another way.

"Otherwise, go and look for it in the tomb of the ancient cultivator?"

In ancient times, the earth had more spiritual energy than it is now, so the treasures of heaven and earth that were bred were more and more advanced.

And those ancient cultivators will definitely choose some heaven and earth treasures as burial objects and place them in the tomb.

Perhaps, among these burial goods, there is something that Su Luo wants to build the foundation.

However, soon, Su Luo rejected the idea again.

"Most of the tombs of ancient cultivators have hidden coordinates of formations, and finding a tomb of an ancient cultivator is probably not easier than it is for me to find something suitable for my own foundation, right?"

"it!"

Thinking about it like this, Su Luo almost couldn't help but burst into foul language.

"It's not going to work...... That's not going to work......

"Could it be that I, Su Luo, will stay in the Qi Refining Realm all the time?"

Because of the pursuit of perfection, it is possible that the actual cultivation speed is even slower than others?

Don't when the time comes, even Long Xiaoxian, a stupid girl, has been promoted to the Jiedan realm, and he Su Luo is still in the Qi refining realm.

So...... Long Xiaoxian's cruel words before may really be fulfilled - he will be beaten all over the ground by Long Xiaoxian looking for teeth!

This...... This is too depressing, isn't it?

"No, calm down, calm down. Su Luo hurriedly comforted himself, waving Long Xiaoxian's stupid face away from his heart.

Good for a while.

Su Luo calmed down.

Immediately, Su Luo took another deep breath.

This time, he began to use all his mind and think hard.

First of all, let's start with the characteristics of the things that build the foundation.

The things that build the foundation can be heaven and earth spirit objects, but they are not limited to heaven and earth spirit objects, and the specific rules are not clear to Su Luo.

But Su Kairong's foundation-building thing, the Heavenly Outer Dark Iron, is obviously not a heaven and earth spiritual thing, which meets the requirements, and also helped Su Kairong build the Heavenly Dao Foundation.

"It's not limited to heaven and earth spirit objects...... Su Luo muttered silently, "This is reminding me, is my thinking too limited?

"But ......" Su Luo frowned again: "Is there any non-heaven and earth spiritual thing that can assist cultivators in building a high-quality Dao foundation?"

Non-heaven and earth spiritual objects, such as gold, diamonds, crystals, alloys, ...... These are also valuable things in human society, and of course they can build the foundation of the road.

However, it is generally a very low-level Dao base, and if you die, your character will be at the top level.

If you want to build a spiritual Dao foundation, it is even more fantastical.

"Perhaps...... Is it because these non-heaven and earth spiritual creatures are too low-level?"

Su Luo pondered.

However, without the nourishment of heaven and earth, will there be more advanced foundation-building things than earth fire, Xuantian polar ice, and innate water avoidance beads?

How is this possible!

Su Luo shook his head again.

But then! Su Luo's face froze suddenly.

Wait a minute!

More advanced than heaven and earth spirits...... What is the foundation?

Su Luo suddenly thought, there really seems to be such a thing on him?

The next moment.

Su Luo looked strange and ...... from the storage bag Take out a stone.

This stone looks very ordinary, and it seems to be no different from the stone on the side of the road.

But in fact, this stone is a strange stone!

At Grandpa Shao Zixi's birthday banquet, Su Luo wanted to give the strange stone to Old Man Shao, but later Old Man Shao felt that he couldn't afford it, so he refused.

As for the origin of this strange stone, according to the memory inheritance in the ancestral dragon fruit-

In the past, a great power of the ancient times, with unimaginable power, moved away the Zhongnan Sacred Mountain, leaving the Zhongnan ruins, and later people simply called the ruins Zhongnan Mountain, becoming the birthplace of Chinese "Taoist culture".

And the real Zhongnan Divine Mountain, but the most holy thing that contains the law of time, that mysterious power, and then used all kinds of strange metals, with the Zhongnan Divine Mountain as the main body, to refine a pagoda - the Tower of Time.

But alas.

The day the Tower of Time was formed.

The mysterious power vanished with the Tower of Time.

One day after endless years, blood rained from the sky, and a void crack cracked in the Chinese sky, and the Tower of Time fell out of it and reappeared in the world.

However, the time tower that reappeared was full of blood.

Subsequently, under the astonished gaze of many cultivators, without warning, the Tower of Time collapsed into nothingness.

Only a piece remained.

It is the stone in Su Luo's hand, and Su Luo calls it the Zhongnan Relic Stone.

This Finale Relic Stone, with a weak law of time, can return the injuries on the body of mortals in the Qi Refining Realm and below the Qi Refining Realm to the state before the injury.

It can be described as life and death, human flesh and bones!

At that time, Su Luo still felt that this Ultimate South Relic Stone was too chicken, and could only treat Qi Refining Realm cultivators.

But now it seems...... 11
