The Yuan Infant Realm is the last realm of the Three Realms of Mortal, and then it is the Three Realms of Cultivating Spirits.

And the catastrophe of the infant is also the most dangerous calamity for the monk before the catastrophe of the nine products, because when he reaches the three realms of raising the gods, the monk crosses the heart tribulation, although the heart tribulation is fierce, but it is often not to death.

However, it is not so simple to promote from the Yuan Infant Realm to the Three Realms of Raising Spirits, firstly, the Yuan Infant Realm requires too many resources, and secondly, the promotion to the Out of Body Realm requires understanding, not a simple spiritual power reserve.

It has been more than 100 years since the old monster of the Tang Kingdom was promoted, and it is only the middle of the Yuan Infant period, which is still the power of the whole country and the accumulation of countless resources.

Shen Yu originally planned to pile Li Dan directly to the peak of Yuanying, and then whether he could be promoted to the out-of-body realm depended on the will of heaven.

But during this time, he consumed too many resources by himself, so he could only stop for the time being, anyway, he was just sitting in the sect, and the Yuanying Initial Realm was enough.

After being promoted, Li Dan has another five hundred years of life, as long as he doesn't provoke those big forces, the Enlightenment Sect can live a peaceful life for at least five or six hundred years.

The point is, with the Four Elephants and Two Instruments Foundation Building Method, for such a long time, the Enlightenment Sect will not be able to produce other geniuses?

The strength of a sect may only require one or two unborn geniuses, but the foundation has to be accumulated slowly.

It is impossible for Shen Yu to guard this place for the rest of his life, he has done what he should do, solved the obsession of the Chongguang Immortal Emperor, and the rest will depend on themselves!

Time to go!

......

During the three days of the banquet in the sect, Shen Yu stayed by the old man's side.

He originally wanted to go back to Ba County a year ago, but after thinking about it, he still didn't leave.

There are too many causes and fruits on their bodies, Shen Banjun and Xie Hongsleeve are mortals, and if they have too much contact, it may not be a good thing for them.

After pondering for a while, he still entrusted the two of them to Li Dan and asked him to help send two pills, if possible, it would be best to introduce them to the Immortal Gate.

Although with the age and qualifications of these two, it is impossible to have any success.

However, after the foundation is built, there is still no big problem in prolonging life, plus those two life-prolonging pills, the husband and wife can also live in the world for more than a hundred years.

That's enough!

The earthly fate is impossible to always accompany himself, at least the current Shen Yu can't do it.

Elder Taishang has lived for nearly a thousand years, and he has no lack of vision and experience, how can he not see that Shen Yu has already made sense?

However, the old man never mentioned it, and after agreeing to the matter, he also took out the invitation to the Thousand Saints Immortal Gate, and insisted that Shen Yu accept it.

The Thousand Saints Immortal Gate was originally the opportunity of the Chongguang Immortal Emperor, but Shen Yu was naturally disrespectful.

He is also a clever person, so he naturally knows that he can't hide the old man's intention to leave, and seeing that his tone is a little reluctant to part, he smiled and relieved: "Elder Taishang, I will go here for a maximum of a year or two, and I will be able to come back in a few months soon, so I don't need to worry!"

Li Dan's eyes lit up, and he was a little surprised, but he didn't ask much.

There are so many secrets in this little guy, many things, it's better not to know than to know.

He and the Enlightenment Sect owe him too much, and what he has to do now is to guard the sect and develop in a low-key manner, if he can help him a little in the future, it will not be in vain.

On October 1, 778, Shen Yu re-entered the underground world, this year, he was nineteen years old!

......

More than four years is not a short time for a mortal, but for a monk, it is just a small part of life.

And for this underground world that seems to exist forever, it is just a drop in the ocean, which will pass in an instant.

When he left here a year and a half ago, Shen Yu had just successfully built a foundation, and there were still too many dangerous places in the underground world that could not be explored, and too many treasures that could not be collected.

However, although he is still building a foundation realm, he is still a thousand petals, and his strength is ten times stronger, plus the Helian Mountain standing behind him, at least in the outer area of the underground world, it can already be swept away.

The first unlucky was the group of two-tailed brown bees, Helian Dashan went to that station, the clanging sound was endless, each spike was equivalent to a blow from the flying sword of the Zhuji monk, but he didn't even lose a piece of oily skin on his body, and the honeycomb of Na Mi Xu was directly ended.

The non-leaking fruit of the Golden Ring Ant has long been taken away by Shen Yu, but the Ant Emperor and the liquid secreted by the Ant Emperor are also good things, so I don't thank you for taking them away.

The two red curly lily are one of the overlords on the periphery of the underground world, and under the waterfall where they live, there are many heavenly and earthly treasures cultivated, last time, Shen Yu only took the Huanxi quinoa, this time, all of them were packed.

There is a little one, whether it is underground or in the water, no treasure of plants and trees can escape its senses.

For a whole month, Shen Yu was like a locust, leaving not a single inch of grass, plowing the entire underground world, and getting so much that the little guy inhaled the cool air and ate with a round belly.

After being promoted, the scales on its body had increased tenfold, becoming nine hundred and ninety-nine, in addition to the previous ones, which were already golden scales, there were more than eight hundred that had not changed, and the next promotion was far away.

However, after such a circle, nearly 100 pieces have turned golden, and this harvest of the month is worth the sum of the two sects of enlightenment and ten thousand laws.

You must know that treasures such as the two-tailed brown bee hive and the ant emperor are not within the ability of the little guy, and all it absorbs is the essence of plants and trees.

Shen Yu also improved a lot, and when he left, he left ninety percent of the elixir essence, but after such a circle, the second lotus platform had nearly a hundred more petals, and now it was five hundred and two.

Ordinary foundation building realm monks, the qualifications between the fourth and sixth grades of the lotus platform are already considered good, if the fifth grade is taken as the middle number, the lotus petals are fifty, and now Shen Yu's spiritual power is thirty times that of the monks of the same level!

Heavy stage and heavy petals, terrifying!

......

Everything was ready, and Shen Yu came to the center of the underground world again.

This time, he was familiar with the way, and he was already a foundation building monk, and there was no shortage of magic weapons and pills, so he easily came to the sinkhole when he was promoted before.

"The end is ahead, in the previous life, the Sogo Immortal Emperor did not succeed for the first time, and he almost fell here, until he was promoted to the Three Realms of Transformation many years later, and then returned here.

Now although I am only building the foundation realm, my strength is more than a hundred times stronger than the ordinary foundation building realm, not to mention that there is not much danger with Helian Mountain!"

On the top of a high mountain, Shen Yu quietly looked ahead, Helian Dashan stood behind him, holding a beast's leg in his hand, gnawing on it.

In fact, no matter how strong he is now, after all, the realm is here, and it is still worse than the Chongguang Immortal Emperor in his previous life.

But the problem is that he has a strategy with him, and he is accompanied by Han Tie Lux, so he naturally has a little more confidence.

"Let's go! Dashan, wait for you to open the way! Oh, these pills are put away, don't take them now, and when you go back, you can't stand it anymore and take another one!"

Pulling Helian Mountain, Shen Yu rose up with his sword.

Ahead, there was a huge abyss, and in the middle of it, there was a pupil-like cyclone, looming under the glow of the rock walls on both sides!
