The countdown of three minutes ended, and Bai Ye was returned to the outer perimeter of Mount Natagumo.
Concurrently, the rewards arrived with the conclusion of the restricted zone, completing randomly.
For the first restricted zone mission, Blood Demon Art, Bai Ye obtained the Spider Demon Father's Blood Demon Art as desired. For the third restricted zone mission, the Blood Demon Art was randomly selected from all the spiders. Bai Ye's luck was decent, acquiring Lower Rank Five's Blood Demon Art.
However…
The unpleasant part was that whenever the word "however" appeared, there was a fifty percent chance of tragedy.
Blood Demon Art - Metamorphosis (Ability) (Green): Blood Demon Art from the Spider Demon Father. Effect: Strengthen Physique (Physical attributes other than Intelligence and Spirit increase by 10 points). Metamorphosis (Under a serious injury state, one metamorphosis can be completed, increasing physical attributes other than Intelligence and Spirit by 20 points, and enhancing one's recovery and regeneration abilities). Remark: This ability requires one to transform into a demon to use.
Blood Demon Art - Thread Trap (Ability) (Blue): Blood Demon Art from the Lower Rank Five of the Twelve Kizuki. Effect: Net Kill (Utilizes hardened and sharp spider silk to form a spiderweb, which can be used to bind enemies or directly slice through the opponent's body). Remark: This ability requires one to transform into a demon to use.
Bai Ye looked at the light screen, feeling like crying without tears.
Metamorphosis was as Bai Ye had guessed, a pure physical strengthening ability. The base increase was indeed ordinary, only a 10-point boost to physical attributes, considering it was only green quality.
But the key lay in the metamorphosis itself.
Metamorphosis had a success rate; it might not always succeed. However, upon success, it provided a 20-point increase to physical attributes and enhanced recovery and regeneration abilities, making it a solid blue-quality ability.
Furthermore, it was considered a higher-tier blue-quality physical strengthening ability, as recovery and regeneration abilities were extremely rare. These two aspects represented survival!
It was classified as green quality purely because metamorphosis was not a hundred percent successful.
As for Rui's Blood Demon Art, there wasn't much to say.
To be honest, if Bai Ye didn't have the South Blazing Fire Sword, Rui wouldn't have been so easy to deal with. Although he could be killed, it would have taken some effort.
Therefore, Rui's spider silk was actually very strong.
Even though it was blue quality, Thread Trap was not Rui's strongest technique, and it could already reach a level close to black quality.
But…
These two useless things, they actually required transforming into a demon to use!
This wasn't a problem for Bai Ye. Bai Ye had obtained demon blood from Rui. But…
Bai Ye didn't want to become a demon!
Turning into a demon for these two abilities was simply not worth it. Although there was the blood of a Demon King that could remove side effects, Bai Ye didn't have any Demon King blood.
Besides, a Demon King, was it that easy to defeat?
Bai Ye felt completely numb.
After all, Bai Ye had visited Mount Natagumo in his previous life but hadn't completed the restricted zone missions.
Without completing the restricted zone missions, he hadn't received the rewards, so it was normal not to know this.
The only fortunate thing was…
Bai Ye hadn't worked for nothing. At least the breathing technique could still be used. And since Bai Ye had only saved Agatsuma Zenitsu, he had obtained the Thunder Breathing technique mastered by Agatsuma Zenitsu as desired.
Thunder Breathing (Breathing Technique) (Blue): One of the five basic breathing techniques, it is the fastest and most explosive among all breathing techniques. It demands extremely high physical conditioning from the user, making it very difficult to cultivate. The ultra-high-speed movement generates a sound like crackling lightning in the air.
Forms (Unlocked) (1/7):
First Form - Thunderclap and Flash: By channeling the breathing technique's power into one leg, one forcefully stomps the ground, unleashing terrifying movement speed. The speed of movement at that instant emits a thunderous sound, executing a quick draw slash at a speed imperceptible even to demons.
Thunder Breathing was what Bai Ye wanted. The reason Bai Ye valued Thunder Breathing over seeking rarer breathing techniques from Tanjiro was…
Speed and explosive power!
Bai Ye didn't lack combat methods, but he lacked auxiliary combat methods.
At the same time, his only movement ability was teleportation.
Undeniably, teleportation was quite useful, but it required operational skill to be useful.
The 2.5-second cooldown and the limit of three consecutive uses placed significant restrictions on teleportation.
Therefore, Bai Ye still needed a means of movement.
Thunder Breathing was excellent. With a total of seven forms, even if the remaining six forms were disregarded, the First Form, Thunderclap and Flash, was sufficient for Bai Ye.
When teleportation was used three consecutive times, all destinations would be reset, and Bai Ye's teleportation would enter a cooldown period.
At this point, he could use Thunderclap and Flash to compensate.
Moreover, by borrowing the time used for Thunderclap and Flash, Bai Ye could re-set his teleportation destination. Then, after Thunderclap and Flash ended, Bai Ye could use teleportation again.
By alternating like this, he could maintain continuous movement!
Therefore, Bai Ye was quite satisfied with the reward of Thunder Breathing. Most importantly, it had no usage restrictions and didn't require him to become a demon.
Of course, there was also the Nichirin Blade.
There wasn't much to say about this thing; it was an ordinary weapon, but it had a boosting effect for using breathing techniques, and the two complemented each other.
However, the breathing technique could still be used without the Nichirin Blade.
Bai Ye received a golden Nichirin Blade that matched the Thunder Breathing technique. White quality…
Bai Ye casually tossed it into his inventory. Its sole purpose was to fill the Gate of Babylon. Furthermore, white quality…
It was truly an insult to the Gate of Babylon.
Even with the boosting effect, Bai Ye would rather use the Frost Condensing Sword or the Famous Sword Bloodthirsty.
Finally, the acquisition of God Stone Fragments made Bai Ye tear up.
Recently, the number of God Stone Fragments had been decreasing. The Steel Slimes were too "gluttonous." Now, with kills and restricted zone mission rewards, he had acquired over twenty pieces, which was a relief.
As for the unusable Blood Demon Arts, Bai Ye didn't dwell on them. There would always be people willing to become demons. Although they couldn't move in sunlight, the improvement in strength was direct.
Those who weren't powerful enough would definitely be willing to sacrifice something to become stronger.
Therefore, they still held trading value.
"Hmm!" Bai Ye murmured, "I recall that in the supernatural areas of the demon world, there are neutral zones. Perhaps where the Demon Slayer Corps headquarters is located. Should I make a trip?"
Demon blood and Blood Demon Arts were too specific for transactions in other areas. However, if it were for the selected individuals in this region, Bai Ye believed many would be interested.
"Then let's make a trip."
Bai Ye made up his mind, but at this moment…
…
