After a long time, the old patriarch left.

Xiang Yu was farming and practicing.

Three more years have passed.

On this day, Xiang Yu was practicing routinely, polishing his true energy, and the spiritual energy was refined one by one, moistening the tendons and veins, part of it moistening the body, and part of it was refined, entering the dantian and circulating into the spiritual energy vortex.

Xiang Yu has carried out this kind of polishing true energy for eight years.

Since the age of sixteen, Xiang Yu entered the ninth level of Qi Refining, he has no way to enter and cannot break through the foundation building.

It can only be to constantly polish the true qi and improve the purity of the true qi.

However, at this moment, the Dantian was trembling violently, and a spiritual vortex appeared and turned into the tenth spiritual vortex.

Click!

Click!

At the moment when the spiritual vortex was formed, Xiang Yu felt a slight swelling and pain in his dantian, and a feeling of tearing was heard.

After a long time, I stopped practicing and gained insight into the Dantian.

In the dantian, ten spiritual vortexes were surging.

A vortex of spiritual energy represents a layer.

"I'm at the tenth level of Qi refining... The Qi refining realm shouldn't be divided into the nineth level of Qi refining! I had an accident and entered the tenth level of Qi refining!"

Xiang Yu was a little puzzled.

After suppressing the impetuousness in his heart, Xiang Yu cleaned up and went to pay homage to the old patriarch, telling his own strangeness.

I trust the old patriarch the most.

Because there is no conflict of interests between them, the old patriarch wants to use him to revitalize the family.

"The Tenth Level of Qi Refining, you really entered the Tenth Level of Qi Refining!"

The old patriarch was also slightly surprised, as if his views were shattered again.

After a long time, the old patriarch said: "This is the first time I have seen the Tenth Qi Refining Level, but since it exists, it should be reasonable and it should exist!"

Xiang Yu said, "It's the first time that the old patriarch has seen the Tenth Level of Qi Refining!"

"yes!"

The old patriarch said: "But at least one thing is certain that many cultivators do not have the chance to refine the tenth level of Qi. As for the reason, it is mainly because there is not enough time."

"The lifespan of Qi Refining Realm is 120 years, but in fact this is the lifespan limit. Many people cannot reach this lifespan limit. Most of them are ninety years old, and they are transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by sitting and transformed by many four spirit roots. Many four spirit roots can barely reach the nine levels of Qi refining in their 90s to early 100s, but their qi and blood are decayed, and they are not in the foundation-building stage!"

"As for the three spiritual roots, they can barely reach the ninth level of Qi refining around the age of sixty, but they cannot touch the tenth level of Qi refining before their life span!"

"The two spiritual roots can touch the tenth level of Qi Refining, but they were at least a hundred years old at that time, and their qi and blood were exhausted. Even with the assistance of the Foundation Establishment Pill, the success rate of impacting the Foundation Establishment Realm is less than one level, which is too dangerous!"

"About the tenth level of Qi Refining, it's just a treatment for the Tianling root!"

The old patriarch sighed that he could only attribute everything he didn't understand to the special nature of the Tianling root.

Then, Xiang Yu proposed the idea of ​​interrogation.

The old patriarch nodded and began to learn.

After the competition, the old patriarch's evaluation was the tenth level of Qi refining, which was comparable to the foundation-building level in combat effectiveness.

After another conversation, Xiang Yu left.

The old patriarch had no answer either.

However, some questions have answers.

The five spiritual roots, four spiritual roots, and three spiritual roots may not necessarily touch the tenth level of Qi refining if they practice until they are transformed. The two spiritual roots can barely enter the tenth level of Qi refining if they are over 100 years old.

But this makes no sense.

If you want to enter the foundation-building realm, it is best to impact before the age of sixty; after the age of sixty, the qi and blood will be exhausted and the success rate will continue to decline.

At the age of sixty, if you impact the foundation building realm, you will have a one-tenth success rate even without the foundation building pill; if you have the foundation building pill assistance, the success rate can be increased to the fifth level.

But if you are a hundred years old and hit the foundation building realm, your success rate is less than one percent.

Therefore, the tenth level of Qi Refining is a treatment belonging to the Tianling root.

"The tenth level of Qi refining has come out, the eleventh level of Qi refining, is it still far from the twelve level of Qi refining?"

Xiang Yu suddenly thought.

It took Xiang Yu eight years to refine Qi from the first level to the ninth level of Qi; it took eight years to refine Qi from the tenth level of Qi; the next level of Qi eleven should be sixteen years; the next level of Qi twelve should be thirty-two years.

Now he is twenty-four years old, and only at the age of seventy-two can he enter the twelfth level of Qi refining.

Moreover, Xiang Yu felt that when he entered the tenth level of Qi refining, his probability of building a foundation decreased.

At the ninth level of Qi Refining, the probability of impacting the foundation building period is 100% successful.

If it becomes the tenth level of Qi Refining, the probability of impacting the foundation building stage is only five.

"The impact of Qi Refining Realm on the foundation building is essentially compressing the spiritual vortex into true liquid. Originally, only nine were needed to be compressed, but now it has changed to ten, and the difficulty has increased, and the success rate has also decreased. If you reach the eleventh level of Qi Refining and the twelfth level of Qi Refining, the success rate will continue to decrease!"

Xiang Yu sighed, feeling that he was digging a hole by himself and killing himself.

"Next, you can't fool it anymore. You must speed up and increase the speed!"

Xiang Yu said in his heart.

In fact, on the first level of Qi refining, Xiang Yu spent half of his time reading books in the library.

The ninth level of Qi refining impacts the tenth level of Qi refining, and it is even more wandering outside without any effort.

Now, we have to work hard.

Time passed, and another seven years passed.

Rumble!

The eleventh spiritual vortex appeared, and Xiang Yu stepped into the eleventh level of Qi refining.

After practicing hard, the time spent is much less.

But Xiang Yu's face turned ashen. At this moment, he was hitting the foundation-building stage and his success rate was less than one level.

At this time, Xiang Yu was 31 years old.

In this year, the old clan leader went out, and another foundation-building elder also went together to buy foundation-building pills.

About a month later, the old patriarch returned with a pale face because he had not bought the Foundation Establishment Pill.

This time, the competition for Foundation Building Pills was particularly fierce. The price of Foundation Building Pills rose to 14,000 spirit stones, and fell into the hands of the Bai family. The Ye family could only return sadly.

Next time, it will take thirty years to buy the Foundation Establishment Pill.

"Sorry, without the concealment of the Foundation Establishment Pill, you cannot reach the Foundation Establishment Period!" said the old patriarch, "It will be able to delay for a while!"

"I see!"

Xiang Yu said.

Many family monks choose to fight back when they are unable to buy foundation building pills, without the foundation building pills to impact foundation building.

The success rate is only one-tenth.

If you fail, you will surely die.

However, if there is a foundation-building pill, you can save your life even if it is not successful.

The old patriarch meant that it would be best to have a foundation-building pill after thirty years; if there is a foundation-building pill, it can also be disguised as if it is an adventure attack.

...

Time passed, and in the blink of an eye, sixteen years passed.

As time passes, the children of the past have become elders.

Accompanied by a roar, Xiang Yu felt his body tremble slightly, and the twelfth spiritual vortex appeared in his dantian.

The twelve layers of Qi Refining have been completed.

But Xiang Yu's face continued to turn blue, and he felt that the success rate of foundation building dropped to one percent.

"The twelve level of Qi Refining is a big pit, and the Tianling roots are killed!"

Xiang Yu was speechless.

One percent success rate, what is the difference between buying a lottery?

At this moment, he is already forty-seven years old.

It's less than thirteen years since I was sixty years old.

Once you are over 60 years old, your qi and blood failure will continue to decline.

There was once a Tianling root who was discovered at the age of 70, and then it took only twenty years to enter the ninth level of Qi refining, and then failed to hit the foundation building.

After getting old, the qi and blood are exhausted and the life span is exhausted, and everything is ruined.
To be continued...
