Zhou Hong continued his operations, merging the remaining puppets. Soon, the hundred thousand puppets were condensed into eight giant puppet behemoths.
"Grandpa, is it done now?" Zhou Hong felt something was still missing.
"Try to have these eight giant puppets form a sword formation and see how powerful it is."
"Okay."
Five minutes later, the test was complete.
Zhou Hong said with some disappointment, "It's no use. Although the power has increased a bit, it still feels like something is lacking."
Zhou Hong's grandfather also couldn't fully predict the outcome and nodded, "Indeed, this slight improvement doesn't mean much."
"Of course, it's not entirely meaningless. At least after forming eight giant puppets, I don't have to be on high alert all the time in the sub-world. The preparation time for the original sword formation can now be completed instantly."
"Then allow me to think carefully again."
At this moment, Zhou Hong suddenly had an inspiration.
"Grandpa, I think I have a bold idea."
"What is it?"
"Each giant puppet now stores 12,500 souls in its brain, which makes the brain too flexible, while the rest of the body is still just limbs controlled by the brain. Can I, perhaps, distribute these 12,500 souls evenly among all parts of the body? Each part of the body would be like a soul-imbued magical artifact. Wouldn't this greatly enhance the flexibility and mobility of each body part, and even significantly strengthen the resistance and adaptability of each body part?"
"That sounds interesting. Then let's try it quickly."
Zhou Hong immediately reconfigured the eight giant puppets, placing the 12,500 souls in various parts of the body: the neck, arms, thighs, and so on. Almost every body part had its own soul. Of course, these individual souls were all controlled by the brain. Thus, the brain's souls accounted for thirty percent, and the brain was further commanded and controlled by Zhou Hong.
After the configuration was complete, the eight giant puppet behemoths instantly transformed into powerful magical artifacts.
Zhou Hong immediately reformed the Eight Immortals Sword Formation.
As expected, after the test, Zhou Hong was overjoyed. The power of the formed sword formation was at least ten times stronger than before.
"Hahaha, it's too powerful, too powerful!" Zhou Hong's grandfather couldn't contain his excitement. A tenfold increase in power meant unimaginable strength. Previously, he could only deal with a low-level Immortal Emperor. Now, he could handle ten Immortal Emperors of the same level. Su Dan Fiction Network.
"Grandpa, now that the power has increased so much, my confidence has grown. But I wonder, what are the grades of Immortal Emperors, and how are their strengths classified?"
"Don't worry, Immortal Emperors are not graded from one to nine."
"Then how do Immortal Emperors know their relative strengths? It's impossible for every Immortal Emperor to be equally strong, right?"
"Although I'm not entirely sure, I guess it must be related to the world force they possess."
"World force?" Zhou Hong suddenly remembered that every Immortal Emperor possessed a sub-world and certainly had world force, although the strength of each Immortal Emperor's world force varied.
Just like Zhou Hong now, he also possessed world force, measured in three stars.
No, three stars was the previous count. Now that Zhou Hong's realm had advanced to Demon King, his world force had naturally increased.
Zhou Hong sensed it and knew his current world force had reached six stars.
However, the amount of world force Zhou Hong possessed was currently meaningless, as he himself was not an Immortal Emperor. The mention of world force here was solely for measuring the strength of those Immortal Emperors.
"Grandpa, my puppet sword formation is ten times stronger now. I wonder what level of Immortal Emperor's strength it's equivalent to."
"That's unclear, but we can make a rough estimate. Ye Chen, whom you killed earlier, I have a general idea of his world force. Although not perfectly accurate, it's roughly estimated to be around seventeen or eighteen."
Zhou Hong was a little surprised.
"That's still quite a lot."
"That's not much. Some have hundreds. He had less than 20, making him the weakest Immortal Emperor."
"Okay, let's assume it's 18. Then, with my sword formation's power increased tenfold, can I deal with an Immortal Emperor with 180 stars of power?"
However, Zhou Hong's grandfather shook his head and said, "It's not calculated like that. An Immortal Emperor with 180 stars of power would definitely be stronger than ten Immortal Emperors with 18 stars of power."
"That's true. Just like ten first-grade Demon Kings would certainly not be able to defeat one second-grade Demon King," Zhou Hong said with a wry smile. If calculated this way, even with a tenfold increase in power, his sword formation could only contend with ten of the same level, and it would be completely insufficient against those of higher levels.
"Zhou Hong, your sword formation's power has increased tenfold. Based on Ye Chen's previous strength, it's roughly comparable to an Immortal Emperor with 30 stars. Because an Immortal Emperor with 30 stars of power is approximately ten times stronger than one with 18 stars."
"Heh, alright, it's still better than before."
"You don't need to worry too much. Being able to contend with an Immortal Emperor with 30 stars is already very powerful," Zhou Hong's grandfather reassured him.
"But what if one comes with 40, or even 50, 100 stars of power?"
"Don't overthink it. You can't achieve instant success. You are only a first-grade Demon King now. Being able to contend with an Immortal Emperor with 30 stars is already extraordinary. Besides, there aren't that many Immortal Emperors. Immortal Emperors exceeding 30 stars aren't running around everywhere."
"Okay." Zhou Hong stopped thinking and had a general idea of his current peak combat power, which gave him some peace of mind.
Without further thought, Zhou Hong left the sub-world.
"Zhou Hong, done?" As soon as he stepped out of the sub-world, he saw Long Yu guarding nearby. After all, Zhou Hong entering the sub-world was extremely dangerous to the outside world.
"Thank you." Zhou Hong was touched to see Long Yu actually guarding him in the secret room.
In fact, if Long Yu had wanted to annex Zhou Hong these past few days, it would have been too easy. Because Long Yu's current realm was higher than Zhou Hong's, Long Yu only needed to cause the secret room's space to collapse, and Zhou Hong would be utterly dead, with his sub-world becoming his.
However, despite such a good opportunity, Long Yu did not do so and instead stood guard.
"No need to be polite. Although this place is in my family's secret room, I can't guarantee 100% safety. So, I came to guard you these past two days. I didn't expect you to come out so quickly. Aren't you going to spend a few more days playing with your wives?" Long Yu chuckled.
"You misunderstood. I didn't enter the sub-world to play with my wives; I went to cultivate...!"
"Wow, congratulations! You are now a first-grade Demon King," Long Yu suddenly exclaimed.
"Speaking of which, I should thank you for the Primordial Immortal Medicine you gave me. I've only absorbed one-third of it. When I finish absorbing it all, I estimate I can challenge for the fourth, or even fifth, grade Demon King."
"Alright, we don't need to be so formal. Let's go. This is your first time in the Immortal Realm, and I must entertain you properly!"
Zhou Hong laughed heartily and, with his arm around Long Yu's shoulders, walked out of the secret room.
