Before Huo Yuhao returned to his room, he first identified the position of the sun, it was only morning, and there was less than an hour before noon, it seemed that the senior brother deliberately asked the second senior brother to call himself early to give himself a time to recuperate.

In the room, a new set of clothes inside and outside was placed on the table, Huo Yuhao quickly went to take a shower, not to mention, taking a hot bath, the fatigue of his body seemed to have disappeared, with his current cultivation, a few days of sleepless is nothing.

Just as he came out of the shower and was about to change his clothes, suddenly, an anxious voice sounded in his head.

"Yu Hao, Yu Hao!" The Snow Emperor's call woke Huo Yuhao, and Huo Yuhao hurriedly asked, "What's wrong with the Snow Emperor?"

The white light flashed, and the Snow Emperor had already appeared in front of Huo Yuhao, and she said eagerly: "What about Xiaobai, he is still in your undead half-plane, I feel that he is a little bad, you hurry up and release it, I am afraid it will encounter a bottleneck." ”

"Huh?" Huo Yuhao was startled, the Ice Bear King Xiaobai and the Snow Emperor were closely related, the Snow Emperor saved it back then and taught it its abilities, so that there was the later Ice Bear King, and there was a close connection between them. When the Snow Emperor said this, there must have been something to discover.

Huo Yuhao didn't dare to slack off, hurriedly recited the spell, opened the door to the undead half-plane, and took the Snow Emperor out in one step, and entered his own undead half-plane.

It didn't matter if he came in, the whole person was stunned. Because within his undead half-plane, there is an unprecedented upheaval.

The entire sky was gloomy, thunder crisscrossed the air, and huge coercion fell from the sky, oppressing countless undead creatures crawling on the ground, only some were particularly powerful. Only then did he dare to look up to the sky and roar in the thunder and lightning, as if he wanted to confront Tianwei.

Ice Bear King Xiaobai was standing on a mountain bag, and it stood there quietly, at this time, he. Extraordinarily calm. It was still humanoid, and there were some food scraps at the corners of its mouth. Its gaze is deep and distant, even with a hint of self-deprecation and contempt.

Standing there, it seemed to have become the core of the entire undead half-plane at this time.

Suddenly, a thunderbolt suddenly fell from the sky. Fiercely slashed on the top of Xiaobai's head, Xiaobai looked up to the sky and roared, the hair on his body stood up instantly, and a layer of ice-blue halo suddenly met the thunder and lightning, intersecting and colliding with the thunder and lightning, the thunder and lightning collapsed, and Xiao Bai's body also shook a little. In his eyes, there was a little more brilliance of thunder and lightning.

"This is ......" Huo Yuhao looked at the Snow Emperor beside him in surprise, and the Snow Emperor's face was solemn at this time, and he said in a deep voice: "It's started." It's already begun. I didn't expect that your half-plane plane had actually reached the level of Cheng dù, which was almost the same as the real one, and this thunder tribulation could also appear. This is the great tribulation that our soul beast cultivation will face every 100,000 years of cultivation. Although each soul beast faces a different catastrophe, there is no doubt that this thunder tribulation is the most dangerous, no wonder I have always felt that Xiaobai could not survive this catastrophe before, it turned out to be a thunder tribulation. ”

Huo Yuhao said: "Then what now? Can we help him? Help him fight against the Thunder Tribulation?"

The Snow Emperor shook his head and said, "No, you can only be sent to death in the past, your cultivation is too bad." If I still have an ontology, maybe there is still a chance, but not now, I am just a spiritual body condensed by spiritual consciousness, and I am most afraid of this thunder and lightning. In the past, too, they had to die. ”

Huo Yuhao said eagerly: "Can we only watch Xiaobai endure this thunderstorm? If it can't resist it, will it die soon?"

At this moment, another thunderbolt had fallen from the sky, and Xiao Bai's struggle this time was much more difficult, not only did he fall backwards, but his body also turned into his body again, and on his shoulders, a piece of hair had turned black.

Emperor Xue immediately made a decision and said: "There is no other way now, but to let Xiaobai bear it, this guy is too greedy, if it returns to the Douluo Continent with you, there will be a long time of calamity, and it is here, we didn't feel it before, we can only let it bear it." If it can withstand it, of course, it is the best, even if it can't bear it, it will not be wiped out with its physical element, as long as it retains a trace of spiritual consciousness for soul transformation, it can be saved back. ”

Huo Yuhao glanced at the Snow Emperor, he was naturally even more helpless now, the Snow Emperor had experienced such a catastrophe seven times, and he had to be more experienced, and now he could only listen to her.

Fortunately, these thunderbolts are only aimed at the Ice Bear King Xiaobai, the sky is getting darker and darker, and the thick clouds are hovering over the mountain pack, if this thunder and lightning can also target the undead creatures, I am afraid that this time the undead half-plane will suffer heavy losses.

"Boom!" Two thunderbolts fell in a row, Xiao Bai relied on his strong physique to release his soul power to the extreme, and a layer of ice-blue shield suspended above its head, brazenly withstanding these two thunderbolts. But Huo Yuhao clearly felt that after this time, Xiaobai's aura became even weaker.

The power of thunder and lightning is vast and vast, full of the righteousness of heaven and earth, and feeling the thunder and lightning at such a close distance, Huo Yuhao only feels as if his body and mind have been baptized by the thunder and lightning.

"Roar-" Xiao Bai looked up to the sky and roared again, his huge body curled up slightly, and then roared up to the sky, a huge pillar of ice blue light rose up into the sky, and slammed towards the clouds, in an instant, with this pillar of light as the center, within a diameter of thousands of meters, it completely turned into a world of ice and snow, snowflakes flew in the air, and the temperature in the air dropped sharply.

Huo Yuhao himself is an extreme ice attribute, and there is also the Snow Emperor by his side, although he is also within this range, he will not suffer any damage.

Xiaobai is fighting back. Huo Yuhao's eyes widened, looking at Xiaobai's results.

As it turned out, Xiaobai's attack did not have much effect.

One after another heavenly thunder continued to fall, forcibly disintegrating the pillar of light it released, although in the end there was still a pillar of light rushing into the cloud of calamity, which made the cloud of calamity obviously weakened a little, but when the pillar of light collapsed, Xiao Bai's body was already shaking, and the soul power fluctuations released from his body were already much weaker.

The blow just now was already a blow with all its strength, before Huo Yuhao and the Snow Emperor arrived, it had been facing the heavenly thunder alone for a short time, and now there was not much soul power left.

The clouds seemed to be enraged, and thunderbolts descended one after another, slashing down at Xiaobai.

Xiaobai looked up at the sky, there was no despair in his eyes, only a strong look. At its forehead, an ice-blue vortex slowly appeared, and the surrounding air currents suddenly fluctuated violently, and it actually withstood the explosion of the thunder.

At the core of the rapidly rotating airflow, Huo Yuhao saw a core shaped like a snowflake, the soul core, which should be the soul core that Xiaobai had cultivated. It turns out that the soul core can still be used like this, and it can be stimulated like this.

While seeing this soul core, Huo Yuhao couldn't help but secretly rejoice, this is the unique ability of Titled Douluo and 100,000-year-old soul beasts! At the beginning, he and his partners had also killed Titled Douluo, but every time he could use luck, if Titled Douluo released his soul core at any cost, then his combat effectiveness would inevitably be greatly improved. But Huo Yuhao could also see that the soul core was already a desperate means used by Xiaobai, and once the soul core was damaged, not only would it endanger his life, but his own cultivation would also fall greatly. Even if you lose your cultivation, you may not be able to say anything. That's why the Titled Douluo rarely thought of using the power of the soul core.

For Huo Yuhao, watching the battle at this time was also a good opportunity to accumulate experience, and being able to witness a fierce beast crossing the catastrophe with his own eyes was extremely rare for human soul masters.

"Boom, boom, boom, boom......" thunder fell, Xiaobai's soul core could be completely resisted at first, but gradually, the breath on its body began to weaken, and the soul core also began to fluctuate unsteadily, in this state, the power of the soul core could no longer completely protect its huge body. Patches of scorched black began to appear on Xiaobai's body, and the whole person was slowly struck by the thunder and sat down on the ground. Its eyes began to grow darker and darker.

"Boom!" A huge ball of lightning fell from the sky, and in the violent roar, Xiaobai's huge body was blasted away, and the airflow around the soul core instantly turned into nothing, only the soul core like a snowflake was still there.

"Xiaobai!" Huo Yuhao shouted, and rushed out almost instantaneously without thinking.

"Yuhao, don't go. "Emperor Xue didn't expect Huo Yuhao to move so fast, and it was too late to stop him. Huo Yuhao teleported to the top of Xiao Bai's head in an instant, and his hands made a movement to support the sky, and a strong extreme ice soul power came out of his body.

In the sky, another ball of lightning condensed, and it fell in an instant in the direction of the Ice Bear King Xiaobai, and Huo Yuhao was between this ball lightning and Xiaobai.

Huo Yuhao's eyes were resolute, of course he knew that it was dangerous for him to do this, but if he didn't do this, he would never forgive himself for the rest of his life.

He couldn't forget Xiao Bai's companionship these days, that grandfather's call, without Xiao Bai, he would not have been able to go deep into Heaven Dou City, the imperial city of the Heaven Dou Empire, and without Xiao Bai, he would not be able to fight against Tangerine. Not to mention infiltrating the camp of the Sun and Moon Empire not long ago.

Xiaobai has always been by his side, has been silently giving, except for eating, but has never asked him for anything. And every time he shot, he spared no effort, and even got injured. Although Huo Yuhao didn't say anything thanks, he always remembered it.
