In Yu Fei's small world, the air was filled with fairy air, but in one place, all the fairy air was dispersed to the side. In the center, there was a giant black stone tablet, which was the Nine Nether Prison Tablet.
Long Yu planned to lend it to Yu Fei for a month, and then take it back before she set out for the alien ancient ruins. After all, when going to the alien ancient ruins, even Yu Fei herself didn't know whether she would encounter any danger, so she couldn't take something that didn't belong to her. There was no use in taking it with her anyway. If something unexpected happened, the Nine Nether Prison Monument would be taken away by others.
"Long Yu, since you lent me the Nine Nether Prison Stele, I can't be too stingy. There is still a lot of spiritual energy in my small world. You can practice here for a while. At least it will be enough for you to practice a new martial arts secret technique to the fifth level."
Concubine Yu said to Long Yu with a smile.
"Oh? Thank you so much, Senior Yu Fei."
When Long Yu heard this, his eyes lit up. He needed the spiritual energy of heaven and earth to improve the realm of Mo Chen's heart. However, the Nine Netherworld was about to collapse, and there was very little spiritual energy left, which was not enough for Long Yu.
Even in other people's small worlds, if one wants to provide enough energy for a person to practice a martial arts secret to the fifth level, it would also require a lot of spiritual energy from heaven and earth. For example, in Yu Fei's small world, it would probably take a month to generate so much spiritual energy from heaven and earth!
Therefore, Long Yu was embarrassed to ask for the spiritual energy of heaven and earth from other powerful people who dominated the secret realm. After all, the small world and the spiritual energy of heaven and earth were the private property of the other party.
Now that Yu Fei is willing to give Long Yu so much spiritual energy from heaven and earth, it can be said to be an extremely generous benefit for Long Yu. However, it will take quite a while to absorb so much spiritual energy from heaven and earth.
"So, I still have to stay here for a while before I leave to accept the battlefield legion mission."
Long Yu thought in his heart, however, since there is a chance to improve the martial arts secret technique of Magic Dust Heart, then he will not give up this opportunity. If he can improve Magic Dust Heart to the fifth level before setting off, then his survivability will be further improved to an unprecedented level.
“If you cultivate the Heart of Demon Dust to the fifth level, the speed of your physical body’s rebirth will be five to ten times faster than before!”
Long Yu had been inside the Nine Nether Prison Monument, so he had some understanding of the effect of the Devil Dust Heart on improving the realm levels. It was a pity that Long Yu had only obtained the cultivation methods for the first three levels of the Devil Dust Heart, and had not yet comprehended the subsequent cultivation methods from the Nine Nether Prison Monument.
"No need to thank me. Logically speaking, the Nine Nether Prison Stele belongs to you. If you are willing to lend me such a treasure for my contemplation, then I must give you something you need in return."
Concubine Yu waved her hand, signaling Long Yu not to be polite.
"Well, but I only have one martial arts secret method that I need to practice, which is the Heart of Demon Dust that I learned from the Nine Nether Prison Monument. For now, I only have the third level of practice method, so it shouldn't require much spiritual energy from heaven and earth."
Long Yu nodded and said.
"Well, go ahead. I'll study the Nine Nether Prison Monument first."
Concubine Yu smiled sweetly, raised her hand to condense the power of the world, and sent Long Yu to another location in the small world. This place has been occupied by the Nine Nether Prison Monument, and there is no spiritual energy from heaven and earth, so if Long Yu wants to absorb the spiritual energy from heaven and earth, he can only go to other places.
In the blink of an eye, Long Yu came to a place with extremely rich spiritual energy of heaven and earth. This was a piece of void in Yu Fei's small world, which contained extremely rich spiritual energy of heaven and earth, which was probably comparable to the top floor of the Nine Netherworld Ladder constructed by Long Yu in the Shenwu World!
"sharp!"
Long Yu couldn't help but feel a little emotional. Perhaps because the Nine Nether Realm had no master and the Nine Nether Dragon Emperor had fallen, the recovery speed of the spiritual energy in the Nine Nether Realm was not fast. Long Yu built a Nine Nether Sky Ladder, which directly consumed all the spiritual energy in the entire Nine Nether Realm within a year.
But now in Yu Fei's small world, there has actually been a place similar to the top floor of the Nine Netherworld Ladder, which is always filled with the spiritual energy of heaven and earth. If one wants to practice any secret martial arts techniques, one can come here directly!
This is really very convenient, but it requires the spiritual energy of heaven and earth in Yu Fei's small world to recover fast enough, otherwise the entire small world will soon collapse.
Long Yu did not waste any time. After arriving here, he immediately began to absorb the spiritual energy of the surrounding heaven and earth, and gathered all of it into his second heart - the Demon Dust Heart.
He still remembered that he had to go to Hongying's room tonight and transfer all the creatures in the Nine Netherworld to Hongying's small world, so he would not spend a long time practicing here with Yu Fei today.
Of course, no time can be wasted. Since he has nothing to do during the day, he might as well absorb the spiritual energy of heaven and earth here.
However, what Long Yu did not expect was that when the Demon Dust Heart began to absorb the spiritual energy of the surrounding heaven and earth, a strange phenomenon suddenly occurred.
The Heart of Demon Dust was actually constantly devouring the spiritual energy of heaven and earth that Long Yu absorbed, but its own strength did not increase!
"Something is wrong. This way of absorbing spiritual energy doesn't seem to be improving the realm of this martial arts secret technique. Could it be that some accident has occurred?"
Long Yu frowned. The Demonic Dust Heart in his body was constantly devouring the spiritual energy of heaven and earth, but there was no change. This situation made Long Yu very puzzled.
"Logically speaking, after absorbing so much spiritual energy from the heaven and earth, this Demon Dust Heart should have changed a bit, but now there is no change at all. It's weird."
Long Yu's brows were furrowed the whole time, as he discovered that the Magic Dust Heart absorbed the spiritual energy of heaven and earth faster than he could actively absorb it. In other words, even if he didn't actively absorb the spiritual energy of heaven and earth around him, the Magic Dust Heart would automatically devour it!
This kind of situation was something Long Yu had never seen before, but he hadn't discovered any harm yet.
"Could it be that if this Demon Dust Heart wants to improve its realm, it must absorb more spiritual energy from heaven and earth? If that's the case, it's fine. I'm just afraid that there are other reasons that caused the Demon Dust Heart to absorb spiritual energy by accident..."
What Long Yu is more worried about now is that the Heart of Mo Chen is now a part of his body. If anything goes wrong with the Heart of Mo Chen, he himself will probably be in trouble as well.
In this state, a day passed quickly. The Heart of Demon Dust had been devouring the spiritual energy of heaven and earth, but there was no change.
"Let's wait for three days. In three days, under such a rich spiritual energy, the ordinary martial arts secrets will definitely be upgraded to the second level. If the Heart of Demon Dust has not been upgraded to the second level by then, I will study it carefully to see what the reason is..."
Long Yu thought to himself that this was the only thing he could do now. However, in just this day, he had absorbed an unimaginable amount of spiritual energy from heaven and earth, which was definitely equivalent to the amount of one hundred endless-grade top-grade pills. Fortunately, the spiritual energy from heaven and earth here at Yu Fei's place was very rich, so he didn't have to worry about being swallowed up completely.
Immediately afterwards, Long Yu had no choice but to leave Yu Fei's small world and go find Hong Ying.
Night gradually fell in Tianya City. Due to the rotation of the Bloodfall Star, this hemisphere soon reached the back of the nearby source of divine text and was no longer illuminated by light.
Long Yu came out of Concubine Yu's residence and went straight to Hongying's room, ready to go to the appointment, and by the way, he transferred all the creatures in the Jiuyou World to Hongying's small world.
This is a huge project, and the main difficulty lies on Hongying's side. After all, the Shenwu World is at least trillions of miles in radius. In order to accommodate so many living beings, Hongying must first create a continent as big as the Shenwu World in her own small world.
This would require a lot of world power... Hongying asked Long Yu to find her tonight, and she must have created this continent within a day. Even if Long Yu just thought about it, he knew that she must be very tired and hard-working.
Long Yu arrived at Hongying's room and found that the room was surrounded by a barrier and outsiders could not enter the room.
"It looks like it's not done yet!"
Long Yu thought about it and could only wait outside her door.
While waiting, Long Yu had nothing to do, so he recalled what happened at yesterday's dinner. The overall atmosphere was very good, especially when Hong Ying took out those endless-level soldiers.
Wei Yuyan, a weapon refining master from the human race, recast an endless-grade super-class war weapon, three endless-grade top-grade war weapons, and fifteen endless-grade mid-grade war weapons for Hong Ying. These endless-grade war weapons are priceless, but at yesterday's dinner, Hong Ying took out a total of eighteen endless-grade war weapons, both top-grade and mid-grade, and distributed them to Long Yu's friends.
There are also some considerations when issuing combat soldiers, mainly to see whether their respective attributes match those of the combat soldiers. Although attribute matching is mainly a problem that only occurs in primordial divine products, at the level of endless-level combat soldiers, if the attributes match, the combat soldiers can obviously exert a more powerful power.
Although there were a lot of endless-level soldiers in this batch, Long Yu had even more friends. After all, there were many people who didn't get them, so Hong Ying also took out some of the ancient-level and prehistoric-level soldiers she had collected, trying to ensure that everyone could improve their strength.
All those who have left the Shenwu world and come to Tianya City on the Bloodfall Star will have to face a cruel life in the outer galaxy in the future, and will often be in danger. With such a powerful weapon, their lives are better protected!
It is very likely that it is because of this endless-level weapon that they were able to survive in the dangerous alien battlefield and have the opportunity to climb to a higher level of martial arts...
As a result, almost everyone was very grateful to Hongying. Even though Hongying said that these endless-level soldiers were obtained by her and Long Yu together, everyone still had a better impression of her.
"This girl, it seems like she's well prepared."
Long Yu found it a little funny when he recalled that the princess of the Blood Demon Clan actually came to get into his bed last night. After distributing endless-level combat soldiers to so many people, others would take it for granted even if they were with Long Yu later, right
