Douluo: Me! Huo Yuhao, Holy Son of Wuhun Palace.

Sunset Forest.

A deep valley was filled with terrifying thunder.

Bibi Dong stared deep into the forest, with dark clouds and lightning flashing in the distance.

Huo Yuhao opened his spiritual eyes and looked across the gaps between many trees.

Deep in the forest, in the center of the valley and the lonely land, where thunderstorms poured down, there grew a dark purple vine plant, with purple mist flashing in the void around it. The vine was absorbing the power of the violent thunder and continued to grow vigorously.

This is - Thunder Hell Vine? !

Huo Yuhao was shocked.

The Thunder Hell Vine is a top-notch plant soul beast with innate wisdom. The place where it grows must be in a place where thunder and lightning are dense.

"Go over and take a look." Bibi Dong suggested.

"Okay." Huo Yuhao nodded, staring into the depths of the forest, his eyes twinkling.

If he remembered correctly, only the Thundering Hell Vine that was more than ten thousand years old could change the celestial phenomena of a region.

Huo Yuhao followed Bibi Dong's steps deep into the jungle and came to a relatively hidden valley.

When they crossed the forest barrier in front of them, they saw a lonely valley with a radius of one kilometer, with a dark purple vine growing in the center. The main vine extended upward, tens of meters high, surrounded by purple mist and flashing lightning. At this time, it is absorbing the pouring thunder.

"What kind of soul beast is that?" Bibi Dong stared at the dark purple vines growing in the lonely open space, with a hint of surprise in her tone.

You know, the plant system itself was defeated by the Thunder Sky, but that dark purple plant could actually absorb the Thunder and become stronger?

"Thunder Hell Vine!" Huo Yuhao said in a deep voice.

Seeing Bibi Dong's confusion, Huo Yuhao explained.

"The soul beast of the Thunder Hell Vine is extremely special. Its cultivation method is very demanding. It requires accumulating hundreds of lightning strikes to gather one year of cultivation."

"This also means that it can only develop when it rains and thunders. The limitations of its cultivation cause its early cultivation speed to be more than ten times slower than other soul beasts."

Bibi Dong was a little surprised when he heard this.

A hundred lightning strikes in exchange for one year of cultivation?

Are these training conditions too harsh?

The cultivation speed is ten times slower, which means that the soul beasts from the same starting point have all entered the ranks of century-old soul beasts, and it has just exceeded ten years. This is another extreme racial talent difference.

"The training conditions in the early stage are so harsh, surely there will be a reversal in the middle and later stages, right?" Bibi Dong looked at the dark wisteria tree bathing in the thunder pond in the distance.

"A hundred lightning strikes will increase one's cultivation level by one year. This is not only a fetter in the early stage, but also a capital for growth in the later stage." Huo Yuhao's tone was solemn.

"Once the Thunder Hell Vine's cultivation exceeds a hundred years, it can actively attract thunder during thunderstorms, strengthen itself, and greatly increase the speed of cultivation."

"After the Thundering Hell Vine has been cultivated to a certain level, it will often cause a thunder pool to appear in an area, and this thunder pool will continue to expand as the Thundering Hell Vine strengthens itself, until it swallows up everything around it." Huo Yuhao introduced.

"Is this why there is no life around?" Bibi Dong stared at the thundering Hell Vine in the center of the lonely valley.

"Why have I never heard of such a powerful soul beast? It's not even circulated in the soul master world?" Bibi Dong asked.

Such a powerful soul beast should be discovered by a soul master.

As the Pope of Wuhun Palace, although she is not an expert in the field of soul beast research, she can still recognize most soul beasts. Even very rare soul beasts can be learned from the data accumulated by Wuhun Palace over the generations. message.

However, she had never heard of the Thundering Hell Vine.

"Because he will blow himself up." Huo Yuhao said calmly.

"The vast majority of thunder hell vines appear in deep mountains and old forests, grow in uninhabited places, and will eventually be destroyed in the process of their growth."

"The thunder accumulated in their bodies is full of destructive aura. Compression will only delay the time of explosion, but in the end, they will usually self-destruct between 20,000 and 50,000 years. Very few can practice for more than 50,000 years. Years of Thunder Hell Vine." Huo Yuhao explained.

It turned out to be the case.

The confusion in Bibi Dong's heart was slightly revealed, and at the same time, a bigger mystery emerged in her heart.

Why does Huo Yuhao know so much about this time? He understands the growth, development, and termination of this kind of soul beast in detail.

At that moment, she was almost certain that there was an extremely powerful soul master force behind Huo Yuhao.

The more profound the power, the more attention it pays to collecting intelligence and compiling the "Soul Beast Record".

Bibi Dong noticed Huo Yuhao's expression, "Do you want to use it as your fourth soul ring?"

"Well, it is true that the main attribute of the Thunder Hell Vine is thunder, but with the baptism of thunder, it is also extremely strong in terms of mental power. After all, it requires distraction to control the vines." Huo Yuhao explained.

"Besides, spiritual soul beasts are really hard to find." Huo Yuhao showed an expression like "I have no choice."

"You should be able to tell the approximate age of that Thunder Hell Vine, right?" Bibi Dong asked.

"Hmm~ Probably around eight thousand years, right?" Huo Yuhao said.

"Are you sure?" Bibi Dong raised her eyebrows.

"The thundering purgatory vine is about twenty meters high and has a radiation range of one thousand meters. The limit is eight thousand years." Huo Yuhao nodded seriously.

"Then what if a black ring explodes later? Let's go?" The corners of Bibi Dong's mouth raised slightly.

These words immediately silenced Huo Yuhao.

"Then... let's go a little further up to eight thousand years."

"When you say a little bit, you mean adding a 'one' in front of it?" Bibi Dong continued to ask.

"Actually, the fourth soul ring, Ten Thousand Years, can also be absorbed." Huo Yuhao said.

Bibi Dong sighed and shook her head.

I had been persuading him for so long, but he didn't listen at all.

"You said you can absorb ten thousand year soul rings now, how can you prove it?"

Huo Yuhao suddenly stopped talking and even felt a little inexplicably irritable.

Leave me alone? !

"Are you sure?" Bibi Dong suddenly asked.

Huo Yuhao nodded immediately.

"Okay, I'll trust you once." Bibi Dong compromised.

"Thank you." Huo Yuhao thanked him sincerely.

In this regard, Bibi Dong was quite helpless.

This little guy is obviously determined to add a ten thousand year soul ring to the fourth soul ring.

Rather than letting him absorb the ten thousand year soul ring while wandering around outside alone, it would be better to do it under her protection.

Combined with his unknown background and familiarity with the Thunder Hell Vine, he shouldn't be joking with his own life.

Moreover, since his second soul ring can be absorbed beyond the level, it seems that it is not impossible for the fourth soul ring to surpass the rules.

"I will take action later, follow me closely, you are only responsible for the final blow, don't cause trouble." Bibi Dong explained.

"Okay, don't worry about this." Huo Yuhao said.

Just as Bibi Dong was about to cross the thunder pond, she was stopped by Huo Yuhao.

Bibi Dong looked back at him, "Is there anything else you want to add?"

Huo Yuhao tapped the center of his eyebrows and immediately activated his spiritual eye martial soul. Three soul rings, yellow, purple, and purple, appeared under his feet.

"I have an auxiliary soul skill that can help you avoid thunder."

Just as Bibi Dong was about to say something, she suddenly received a third-party perspective. The whole world became clear, and the observation was meticulous and detailed.
