Even if it is not an imported product, Three Holy Lands is certainly not the original author.

As for the toad oil that appears in the original book and is used to assist cultivation, this can also be explained clearly.

The inheritance of the Three Holy Lands did not appear after Kaguya Otsutsuki came to the ninja world.

Before Kaguya Otsutsuki came, the three holy places had always had inheritance.

And with the ‘Grel Civilization’ that thrived on the Grel Ore, the Ancestral Country and the Other Country looked like new civilizations re-established after experiencing the Dark Ages.

After all, it was stated in the original work that the ‘Grel Civilization’ indeed had the ability to travel across oceans.

‘The movie about the Greel Ore didn’t specify where the ruins containing the Greel Mine are.’

Qianye could only guess that the ruins were in the southwest region of the Country of Fire based on the environment flashed in the original work.

The southwest area is full of mountains and rocky canyons. Because it is close to the desert of the Kingdom of Wind, the vegetation is not very lush.

'We must find a way to find the caravan in the original work.'

In all likelihood, the leader of the caravan that appeared in the original book knew the specific location of the ruins.

It is very difficult to find an elusive traveling trader, but no matter how high the price is, it is much better than searching for a needle in a haystack in the vast southwest region.

Qianye took a few breaths and adjusted his mentality.

"Sana, after you finish eating, work hard and write down the inheritance you received in the abyss of the earth, word for word."

"Just write the first two parts first."

"It will not be hard for Sana if she can help the teacher."

...

With the mission in hand, Sana eats much faster.

After filling her stomach, she found paper and pen from Qianye and went to her desk to copy.

Qianye stayed aside and practiced with his shadow clone.

The Sand Ninjas were not idle either. Under the leadership of the Konoha Ninjas, they were cleaning up the ruins of Loulan.

The productivity of the ninja is really strong. Without the need to cover up their tracks, one-tenth of the area was cleared in half a day.

Two hours later, Sana put down her sore wrist from copying and handed the results to Qianye, waiting for his review.

Qianye took over the results of Sana's hard work and first used medical ninjutsu to treat Sana's wrist: "Thank you for your hard work, Sana."

Her painful wrist suddenly felt much better.

Sana chuckled and said: "No hard work, teacher, it's still early. Can I ask the teacher's shadow clone to learn how to refine chakra?"

"No problem. If you are tired, remember to take a rest. Studying blindly will not work. Combining work and rest is the way to go."

"Yeah, well, then Sana will go first. Teacher, if anything happens, call me."

"Go ahead."

The shadow clone took Sana to find a quiet place and started teaching.

Qianye sat on the ground and read through the knowledge transcribed by Sana.

How to control and use the dragon veins was temporarily skipped by Qianye, and his energy was completely concentrated on the 'Grel Ore' part.

Qianye's mind was quickly attracted by this new training system.

Upon seeing this, the Shadow Guards dispersed the Sand Ninja working around them and asked them to go further to clean up the ruins of the ruins so as not to disturb Qianye.

Time passed quickly, and the dry firewood crackled from time to time in the flames.

The loyal guards of the Shadow Guard are nearby.

An hour later, Qianye put down the scroll and breathed a long sigh of relief.

After reading this part of the knowledge recorded by Sana, his feeling that Greer Ore is natural energy became stronger.

A small number of people in the Greer civilization absorbed the energy contained in the ore and gained all kinds of incredible powers.

The physical body has been greatly strengthened, and the reaction force and healing power have been greatly increased. At the same time, it can also control fire, thunder, wind, raging waves, giant rocks, etc.

In this regard, natural energy also has similar characteristics.

Natural energy is also divided into many types.

Different amplification effects can be obtained by absorbing different natural energies.

For example, Jugo's physical activation ability is very different from Naruto's sage mode.

The former's body has truly become a dangerous biological weapon.

The scroll transcribed by Sana also records that when absorbing Grayl Ore, the absorber faces a very terrifying danger. If he is not careful, his body will have an alienation reaction.

This is also consistent with the abnormal symptoms that occur after absorbing natural energy.

Regarding Loulan's dragon vein, there is also a clear record in another scroll.

Sana's ancestor directly explained why he chose this place.

Dragon Veins does not have any attributes, and precisely because of this it does not have any attributes, so compared to other energies, it has more possibilities and can be used in more fields.

After experiments, Sana's ancestors discovered that dragon veins without attributes can enhance other attributes. The effect of amplification and enhancement is very significant, and it can also be used directly as energy.

'So, the Greer Civilization is really the real prehistoric civilization of this world?'

Prehistoric civilization is not necessarily a backward, ancient civilization that only knows how to throw stones.

Sanai's ancestors developed a powerful civilization through the Grayl Ore, but eventually fell because of it.

Everything is hidden in the years and becomes a speck of dust.

'Perhaps it was the Greel civilization's high-level exploitation of Greel's ore that attracted the Otsutsuki clan, who believed that this planet had extremely high colonial value and could be planted with sacred trees.'

The sacred tree absorbs the natural energy of this world and directly turns a territory into an endless sea of ​​sand.

But there are still many areas left.

Just by draining the natural energy of a territory, a chakra fruit was created, which shows how profound the foundation of this world is.

It’s no wonder that the successors of the Otsutsuki clan cherish this place very much.

If it were him, he would never forget the ninja world.

"Wealth without sufficient strength is not wealth, but disaster."

The Otsutsuki clan are very dangerous interstellar colonists.

But on the other hand, when Qianye's strength reaches another level, the dangerous Otsutsuki clan becomes wealth in Qianye's eyes.

'Farm with peace of mind, promote the development of science and technology in the ninja world, and promote the development of ninja civilization in the ninja world. I will use the essence of this world as my foundation to achieve my ultimate goal.'

eternal life!

Qianye continued to read, and when he saw the words at the end, his face became a little ugly:

'No wonder the leaders of Loulan who followed were worse off with each generation. In the end, even this inheritance was lost, and they ended up with the tragic end of the country's destruction.'

These two scrolls respectively record how to use Greer Ore to practice and how to use Dragon Veins to practice.

The relationship between the two is inseparable.

As long as the former is completed, you can proceed step by step to the second step, using dragon veins to practice.

but......

There is a prerequisite here.

That means there must be a piece of Grayel Ore as a primer.

This stuff is a non-renewable resource and is difficult to discover by conventional means.

Sanai's ancestor only took a small amount of ore with him when he left, and at the same time he lacked the knowledge on how to prospect and find the Grayl ore veins, which meant that he used less of the Grayl ore in his hands.

This is quite normal.

Just like so many students in previous lives, do they know how to find mineral veins after studying geography in middle and high school?

Isn't that nonsense?

Only after receiving professional training and receiving systematic study can we learn this knowledge.

So it’s normal for Sana’s ancestors to not understand.

Her ancestor realized that after the part of the Greer ore he carried was used up, his descendants would face the dilemma of having an empty treasure mountain but no way to enter it.

Thanks to his talent and intelligence, he used secret methods to ensure that his direct bloodline could control the energy of the dragon vein even without the introduction of Greer Ore.

Note that this is just manipulation, you cannot use the energy of dragon veins to strengthen your body.

Dragon vein energy has no attributes and is relatively stable, but that does not mean it is gentle and harmless.

Just absorb it and wait to die.

Qianye closed the scroll: 'Now things have fallen into a cycle. If I want to use dragon veins to practice the immortal mode, I need to use Grayel Ore as an introduction. And if I want to use Grayel Ore to get started, I must first have Sana's.

Bloodline.'
