Mysterious I Came a Billion Years Later.

Lin Tian explained with a smile: "Immortal medicine is not enough. The thing in it is called innate holy water. After drinking it, it can prolong life by about 20 years, and it can also restore youth. Dad just drank innate holy water. Back to youth status and 20 years of life extension."

"20 years of life extension!"

When Lin Tongsheng heard this, his pupils dilated, and he couldn't help being surprised.

Lifespan is a problem that humans have been unable to overcome, and his son actually gave him a bottle of innate holy water that can prolong his life by 20 years, which really impacted his concept.

"Parents, sister, this thing is not ordinary, don't publicize it, just know it yourself!"

Lin Tian quickly reminded.

If the congenital holy water thing leaked out, it would be no small trouble.

Although he is not afraid of trouble, he does not want trouble either.

"Okay, of course things like this won't be advertised."

Lin Tongsheng still knew the importance and hurriedly promised.

"Mom, sister, drink it too!"

Lin Tian said.

"Okay, I'll drink!"

Xu Xiulian quickly drank the innate holy water in one gulp.

It is a woman's dream to regain her youth. Although she is old, she still has a heart for beauty.

When Xu Xiulian swallowed the innate holy water, her appearance also changed, from an aunt to a beautiful young woman in her thirties, and her skin was better than that of ordinary girls.

"Wife, you are even more beautiful now than you were when you were young!"

Lin Tongsheng praised.

After Lin Xuanxuan drank the innate holy water, not much changed, after all, she was very young.

She just has better skin and the dark circles are gone.

Restore youth and prolong life by thirty years.

Lin Tian's parents were very happy, as if they had really returned to their youth.

Seeing his parents so happy, Lin Tian couldn't help feeling that it was worth it.

After staying at home for a few days, Lin Tian was ready to leave.

Xiao Xiner is going to participate in the exchange meeting of Galaxy University. As Xiao Xiner's guardian spirit, he naturally has to practice hard to assist Xiao Xiner.

Back in the Galaxy Era, Lin Tian and Xiao Xiner worked hard to cultivate together again, and they often discussed matters related to cultivation.

In a flash, another few months passed.

At this point, there are only ten days left before the half-year deadline.

In the past six months, Xiao Xiner has made great progress.

She is no longer in the seventh level of the innate, but has reached the tenth level of the innate, which is an achievement obtained by crazy cultivation.

And Lin Tian is also in the tenth level of the innate, but he has crossed the tenth level of the innate early, and Xiao Xiner has just barely stepped into this level.

In addition, the two people's Chinese martial arts progress is very fast, far more powerful than half a year ago.

For Lin Tian, ​​the next moment is a critical moment to impact the spiritual realm.

The spiritual realm is different from the congenital realm. Innate cultivation is the innate real energy, while the innate real yuan is transformed into a sea of ​​​​divine.

The meaning of the spiritual realm represents the road to the gods. The innate essence in the dantian turns into the ocean, which is the sea of ​​​​divine.

Moreover, the soul of the spiritual realm will also change, giving birth to divine consciousness.

Divine Consciousness is the condensation of spiritual power. Spiritual power is very loose, while Divine Consciousness is extremely strong, far stronger than spiritual power.

Therefore, an awakened person with the first level of psychic realm can easily kill an awakened person with the ninth level of congenital innate.

Only geniuses like Xiao Xiner and Zuo Zi can kill their opponents at a great level.

However, [-]% of the innate cannot step into the spiritual realm.

The bottleneck of the innate impact on the psychic realm is very strong, and many awakened people who lack the ninth level of congenital background cannot succeed in the impact at all.

Therefore, the law of the Spiritual Realm is particularly important.

Some ordinary spiritual cultivation techniques can only barely expand the dantian, so that the innate true essence can be transformed into a divine sea, but such a divine sea is just an ordinary divine sea with insufficient potential.

The Divine Sea of ​​some Heaven's Chosen Sons is accompanied by various visions.

There are towering ancient trees, phantoms of ancient beasts, and reflections of the stars...

Once a vision is born, it must be the top Divine Sea.

Lin Tian had already prepared for the cultivation technique of the Spiritual Realm——

"Jiuding Divine Refinement!"

This practice method appeared in Lin Tian's mind.

This is a Taoist practice, and it is a Taoist practice recorded in the book "Xingming Guizhi Quanshu", a monograph on Qigong Inner Alchemy.
