Looking at the attribute information light curtain in front of him, Hong Yu was a little dumbfounded, he didn't expect the system upgrade to make such a thing, he knew his level, the level and qualification of the heavenly demon at a glance, and the column of the origin path was not difficult to understand, that was to quantify his 'degree of control' of the four origin paths, the higher the number of steps, the higher the degree of control, however, he was a little unclear about the 'source power exchange' column.

Later, Hong Yu communicated with Nicole the little penguin, and learned that the upgraded system can actually speed up the strengthening effect of the demon star by consuming source power, or use source power to exchange source value.

In layman's terms, consuming source power can make the level of the Heavenly Demon increase faster, or make the origin value higher, that is, make his level increase faster!

After becoming an overlord, from the original cultivation domineering energy to the current cultivation of the origin path, the higher the degree of control of the origin path, the higher the personal level, and in the case of multiple origin paths, the personal level is the same as the one with the highest degree of control.

Hong Yu naturally wanted to improve his level at the first time, but then he found that the source power he currently possessed in the abyss was enough to increase the origin value by one or two steps, and the ten-step origin value could only allow him to upgrade from a one-star overlord to a two-star level, so it was really not cost-effective.

Of course, the source power in the abyss is far from reaching the level of 'full' now, and it is only about one-fifth of the depth, but even so, it is extremely uneconomical to consume so much source power in exchange for the origin value.

And in terms of accelerating the level of the Heavenly Demon, Hong Yu probed and found that it was very good, to raise those Heavenly Demons below his own level, it does not need to consume too much source power, of course, if you want to improve the Heavenly Demon with a higher level than yourself, the consumption is also quite terrifying, such as gluttony, its strength is already a five-star Demon Emperor, and even if he uses all the source power, it is not enough to improve the other party's one-star.

For a long time, because his level jumped too fast, those heavenly demons couldn't catch up with him in the short term, which led to the fact that these heavenly demons often couldn't help much because of their low level, but now with the source power exchange system, it seems that this problem can be solved.

Next, the Heavenly Demons who received the reinforcement in the Demon Star were surprised to find that the Demon Star's enhancement of them was greatly accelerated, and the degree of acceleration made them all a little shocked, and in a short period of time, their strength actually skyrocketed upward!

Breakthrough! Six-star demon king!

Breakthrough! Seven-Star Demon King!

Breakthrough! Eight-Star Demon King!

Breakthrough! Nine-Star Demon King!

......

Breakthrough! One-Star Demon Emperor!

It is worth mentioning that the other Heavenly Demons are fine, but the Ten Thousand Devouring Ants are a little different, because their number is so large that after being promoted to the Nine-Star Demon King, when he wants to further improve, Hong Yu found that even if he consumes all his source power, he can't do it, so he raised the level of one hundred of the 'Flying Ten Thousand Devouring Ants' to the Overlord, and the other 'Land Ten Thousand Devouring Ants' temporarily stopped their cultivation at the Nine-Star Overlord stage.

Although this promotion consumed more than half of Hong Yu's source power reserves, the cost performance was extremely high, and it suddenly gave him more than a hundred overlord demon pets, assuming that he faced Yu Wenhao again, these demon pets alone would be enough for the other party to drink a pot.

Of course, the reason why Hong Yu was able to consume source power to increase the level of the demon pet was thanks to the majestic source power he possessed in the abyss, and if it was someone else, the little source power in their spirit lake was not enough to squander it so much.

In the heavenly demon space, seeing the level of other demon pets rising, the greedy and jealous ghosts cried wolf howls and shouts, Hong Yu can only ignore this, the level of gluttony is too high, and his source power is not enough for the other party to upgrade.

After this large-scale collective upgrade, the appearance of the Heavenly Demons has taken on a new look, the beautiful snake has become more and more enchanting, the breath on the eight-eyed spider is powerful and terrifying, the scale armor of the Void Beast's body is shining, the feathers on the nine-colored peacock have become more mysterious and colorful, and the ten thousand devouring ants are even more imposing!

If you want to say that the biggest change is the Lost Beast, this big snail after being upgraded to the Demon Emperor, it actually spits out a strange 'black aperture' from time to time, but every time it seems to be overwhelmed, before the black aperture is completely revealed, it has no strength to maintain it, and the aperture will shatter and dissipate.

What made Hong Yu feel horrified was that the moment the black aperture shattered, it would produce an extremely terrifying 'space explosion', its power was even more terrifying than the violent fluctuations when the super color bubble was broken, and when the 'space explosion' occurred, it could even tear the surrounding void into hideous spatial cracks!

Looking at the black circle of light that had just disappeared and the dark space crack that appeared afterwards, Hong Yu's heart was hot, this was definitely his sharpest attack at the moment, with this hole card, even if he encountered an opponent who was much stronger than Yu Wenhao, he also had the confidence to fight with it.

Hong Yu's gaze moved away from the demon pets such as the Lost Beast, and glanced at the gluttony who was still distressed, and the corners of his mouth couldn't help but appear a smile, although this product didn't get the acceleration and strengthening, but in the previous battle, he used black gas to grab a hill-like green energy, which was much more than when he was in the Southern Xinjiang Academy, with their 'nourishment', the terrifying injury on the glutton's body was not only healed a long time ago, but its strength was also rapidly improving.

At the same time, the experience demon on the gluttonous body didn't need money, and it poured into his body like a torrent, rapidly increasing the source power in the abyss.

It can be said that after this battle, Hong Yu's strength has undergone a qualitative transformation, if he was the elite of the second-rate forces before, then now he can barely gain a foothold even in the first-class forces.

Hong Yu's eyes then couldn't help but look at the bottom of the abyss below 20,000 meters, and there was a hint of doubt in his eyes, because, when he broke through the overlord, the abyss deepened from 18,000 meters to 20,000 meters...... On the other side of the abyss, it's as if there's a new world!

If the abyss continues to deepen, what will happen 20,000 meters below?

Sensing the mysterious abyss, Hong Yu fell into deep thought.
