Delta Stream is Mega Rayquaza's ability. Its effect is to cover its two old rivals, Groudon's Desolate Land and Kyogre's Primordial Sea, and make the flying type's weaknesses disappear.
Just looking at the description might not seem very strong, but if you understand Pokémon, you'll know the value of being able to override the abilities Desolate Land and Primordial Sea.
Desolate Land: The weather changes to a special harsh sunlight, the power of fire-type moves is greatly increased, and water-type moves cannot be used.
Primordial Sea: The weather changes to a special heavy rain, the power of water-type moves is greatly increased, and fire-type attacking moves cannot be used.
Relying on these two abilities and the extremely strong base stats of Groudon and Kyogre after Primal Reversion, they could almost be said to have dominated an era, with only a few strong individuals like Mega Rayquaza being able to contend.
Even now, Kyogre is still a symbol of strength. People have even created a dedicated unit of measurement for it, 'one Kyogre'.
But unlike the smallest units of measurement in other works, this unit of measurement for Kyogre represents extreme strength.
If a Pokémon's normal form can deal 'one Kyogre' of damage in one turn, it means that this Pokémon possesses a kind of beauty in its strength.
Since Mo Hui named his new self-created soul skill Delta Stream, it naturally has a similar effect to Mega Rayquaza's ability.
Within Mo Hui's soul skill range, other domains will be covered and invalidated. Furthermore, any attribute soul skill attacking Mo Hui will first be weakened by the domain. Wind attribute attacks are even worse, they will be directly absorbed and extinguished, thus maintaining the domain's duration.
In addition, since this move evolved from Shun Feng (tailwind), this soul skill also retains the effect of Shun Feng (tailwind). Within the domain's range, Mo Hui and Pidgeot's speed will be greatly increased.
A moment later, Mo Hui finally calmed down from his joyful mood, looking at the special area in front of him with eyes full of longing.
He had only observed this special area for a while and had gained such a great harvest. If he observed more or even entered it, what kind of harvest would he gain?
But soon, Mo Hui sighed. Although he was now a Soul King, the altitude of 30,000 meters was still too draining for him. The thin oxygen and external cold, these extreme environments were all restricting him.
Just staying there for this short while, his soul power reserves were already less than a tenth. If he didn't go back, what awaited him would be soul power exhaustion and falling from an altitude of 30,000 meters.
And because there was no soul power protection, it was very likely that he would suffer irreversible damage from the extreme cold and lack of oxygen at this high altitude before even reaching the ground.
"It's time to go back."
Mo Hui gave a regretful look at the special area not far away, then piloted Pidgeot to dive downwards.
Compared to flying upwards, flying downwards was obviously much easier. Before long, Mo Hui arrived at a deserted corner near the Heaven Dou Great Spirit Arena and walked out.
At this moment, Mo Hui suddenly looked up at the sky, a trace of an inexplicable look appearing in his eyes.
It seemed there were still many things he didn't know about on this Douluo Continent.
Immediately, Mo Hui smiled and shook his head, then walked into the Heaven Dou Great Spirit Arena.
In the Shenfeng Academy area, Feng Qingcang saw Mo Hui arrive, and a knowing smile immediately appeared on his face. He said, "Mo Hui, you're here? But you're a bit late. Just now, Xiao Tian has already led Yun Fan and the others onto the stage to compete."
"It's okay, I wasn't planning to go on stage anyway, just watching is fine."
Hearing Feng Qingcang's words, Mo Hui replied.
"Just watching? You're not planning to go on stage?"
Hearing this, Feng Qingcang was slightly taken aback, then carefully sized up Mo Hui and said in surprise, "What were you doing just now? Why does your soul power feel so low?"
"I did take care of something just now, which consumed some soul power," Mo Hui replied with a slight smile.
"And..." At this point, Mo Hui suddenly changed the subject and said, "If I go on stage, the battle won't be interesting, will it?"
"That's true!"
Hearing this, Feng Qingcang was silent for a moment, then nodded in agreement.
Mo Hui's strength was truly too great, especially against opponents lower in rank than him. It was simply a nightmare, with no chance of winning.
In fact, let alone others, even when he faced Mo Hui, besides relying on sheer power to overwhelm him, he didn't have any particularly good solutions.
After all, Mo Hui's martial soul's speed was too fast. Even he, a Wind attribute Soul Douluo, couldn't keep up. Only by relying on external soul power release and some special control methods was it possible to catch Mo Hui's Pidgeot.
But that was only a possibility. In reality, once Mo Hui was prepared, with his speed, no one could catch up. Pidgeot's speed is faster than your soul skills, how can you fight that?
Mo Hui's timing was very clever. As soon as he sat down, he heard the referee's voice on the Douhun Arena.
"Preliminary Round 23, Match 8: Shenfeng Academy vs. Tianshui Academy."
Students from both academies entered simultaneously. In the Tianshui Academy team, Shui Bing'er was slightly taken aback when she saw Feng Xiaotian and said, "Feng Xiaotian, why is it you? Where is Mo Hui?"
"Hey, hey, what do you mean by that? Are you looking down on me?"
Hearing Shui Bing'er directly ignore him and ask about Mo Hui, Feng Xiaotian immediately raised an eyebrow and said somewhat unhappily.
Shui Bing'er explained, "Your strength is certainly very strong, but I want to fight Mo Hui more."
Although Shui Bing'er knew she would likely not be able to defeat Mo Hui after witnessing his battle against Thunderclap Academy, she had cultivated for so long precisely to have another fight with Mo Hui. How could she possibly admit defeat without even fighting a single match?
"Then you're going to be disappointed. Mo Hui didn't come to the competition venue today."
Hearing this, Feng Xiaotian replied.
Immediately after, Feng Xiaotian subconsciously glanced towards the Shenfeng Academy area, and then he saw Mo Hui already sitting there watching the show. His face instantly darkened, and he quickly corrected himself, "I misspoke. He wasn't here when I went on stage just now, but now he's below, watching our battle."
Hearing this, Shui Bing'er also looked towards the Shenfeng Academy area and then saw Mo Hui nodding at her.
"Enough talk, let's just start fighting!"
Subsequently, Feng Xiaotian immediately activated his martial soul and, after the referee announced the start, without any hesitation, condensed a huge Wind Blade.
Upon seeing the enormous Wind Blade, Shui Bing'er's pupils immediately contracted, and she exclaimed, "Isn't that Mo Hui's self-created soul skill? How do you know it too?"
