The stunned look on the face of the ancient proverb did not last long, but faded with the unruly look of the handsome young man in front of him.

If it weren't for the powerful and cold aura of the handsome young man in front of him and the unstoppable expression, the ancient proverb would definitely not be able to connect him with that peerless beast.

"Stinky boy, you can give this seat a nickname casually, be careful that this seat slaughters you!" As soon as the ancient proverb came out, Xiao Jiu was as if he had been stepped on his tail, and immediately became irritable and said angrily. Obviously, as a proud beast, it is very resistant to the rude behavior of the old proverb.

Ignoring Xiao Jiu's angry shouts, Gu Yan closed his eyes and felt the situation in his body, under the baptism of those terrifying thunders, his physical body transformed again, exuding a faint breath of rebirth. Looking at this situation, it is obvious that his body has undergone earth-shaking changes.

"Even destroying the black thunder can be introduced into the body for tempering, what a little monster!" Tang Wu'er walked forward, looking at the young man who was not only fine, but his aura was getting stronger and stronger, and sighed.

The old proverb shrugged his shoulders slightly proudly, and his demeanor was quite flat. Of course, what Tang Wu'er said is also true, the ancient proverb is indeed worthy of the word monster.

Ordinary people, if they want to introduce that ruined black thunder into their bodies, they have already been torn apart by the violent power of the thunder before they have time to quench their bodies. But the ancient proverb is different, he has a tombstone as an inner pill, which can introduce thunder into it, plus his physical strength can withstand the power of thunder in a short time.

And the main reason for the success of the ancient proverb is that the magical warming effect of the origin spiritual power is indispensable, plus he has awakened a trace of the power of the bloodline of the Nine Demon Jiao, and has the healing power of the immortal beast, which is worthy of withstanding the impact of the destruction of the black thunder with his strong will.

"Demon Flame Sect, wait, when the young master leaves here, it will make you restless!" Gu Yan stood up, looked up towards the mountain stream, and felt the unprecedented power in his body, the faint way.

After a period of time, Gu Yan absorbed the thunder rolling on several surrounding mountain peaks into his body, and the pent-up power in his body also reached a terrifying Cheng Dù, which was his preparation for breaking through to the rebirth realm later.

The ancient proverb has three attributes, and even he is very much looking forward to what will happen if he breaks through to the rebirth realm.

Unconsciously, it has been several months since the two of them and one beast came to the mountain stream of the Demon Cave.

On this day, the ancient proverb once again introduced all the black thunder on a mountain peak into the body, and when some of them were still unfinished, they suddenly heard the earth-shattering roar from the distant mountain peak.

"There are other demon beasts here?"

As a demon beast, Xiao Jiu was obviously extremely familiar with this violent and monstrous aura, and immediately turned into a demon beast form and flew into the sky to find out. Because of that breath, even it was a little stunned.

On the top of that distant huge mountain, thunder raged in the sky, and faintly, a huge beast shadow could be seen, which seemed to be fighting with the thunder!

During the raging thunder, it also made the two Gu Yan see the true appearance of the demon beast. This is a huge silver beast, in terms of size, a few points bigger than Xiao Jiu, silver scales cover the whole body, is flashing thunder, thick and powerful limbs slammed on the peak, with the extremely violent aura swept away, the huge mountain peak was also cracked by the force.

"What a terrifying aura, what kind of demon beast is that?" Even from a distance, Tang Wu'er could still feel the violent aura from that giant beast, and immediately said in a solemn voice.

"Is that legend really true, during the conversation with everyone in the Blood Cave Gate, Yu Chi Lianyun once mentioned one thing, saying that in this demon cave mountain stream, there is an extremely terrifying demon beast, called the Thunder Swallowing Heavenly Lion!" The ancient proverb frowned slightly, this Thunder Swallowing Heavenly Lion specializes in devouring and destroying black thunder, and its strength is extremely strong.

The world is full of wonders, the Thunder-Swallowing Sky Lion has a strange nature, and it actually relies on the power of Devouring Thunder to evolve, in addition to its violent temperament, the body that has been tempered by thunder all the year round is even more powerful to the extreme.

"It seems that it is preparing to cross the catastrophe?" Feeling the power of the heart palpitations and thunder emanating from the Thunder Devouring Heavenly Lion's body, Gu Yan muttered thoughtfully.

As a strange beast that devours thunder, the thunder tribulation ushered in by the thunder devouring heavenly lion is obviously more violent than the ordinary thunder tribulation, only to see that on the sky dome where the thunderclouds are tumbling, the more and more violent thunderclouds continue to condense, and the weird black light flickers, the power of thunder is indescribably furious.

The Heavenly Tribulation, for any spiritual cultivator, is an inevitable hurdle on the path of cultivation. Once you step into the Rebirth Realm, all Heavenly Tribulations will appear in the form of Thunder Tribulation, but different Thunder Tribulations such as Flame Thunder Tribulation and Wind Thunder Tribulation will appear according to different attributes.

For the Thunder Swallowing Liens, in the long battle against the ruined black thunder, it is very much looking forward to ushering in the reborn thunder tribulation every time, but it is extremely afraid of it.

The ever-forming Thunder Tribulation seemed to feel the challenge of the Thunder Devouring Heavenly Lion, and suddenly the black cloud squirmed, and a terrifying power of heaven and earth shrouded it.

"Let's hide it first and see if we can reap the profits!" Feeling the thunderstorm full of ruining power in the distant sky, Gu Yan keenly sensed that the opportunity was coming, and immediately pulled Tang Wu'er to hide in the dark.

The more terrifying power of thunder, frantically converging in the thunderclouds, that kind of terrible fluctuations, compared to the previous ruined black thunder, it was simply a cloud of mud. The old proverb thinks that this kind of thunderstorm, with his strength, he will die if he touches it.

The thundercloud was torn apart violently, and the sound of the heavens and the earth was frozen at this time, and a huge pitch-black thunderbolt, directly carrying the power of destruction, fell from the sky and slammed into the thunder-swallowing lion.

Thundered!

One after another black thunder pierced through the heavens and the earth, and finally bombarded the body of the Thunder Devouring Heavenly Lion's flickering thunder, each time the black thunder fell, a dazzling thunder mang collapsed on its body, and it was a roar of pain, and its slightly trembling body showed that it was suffering great pain.

The thunderclouds rolled, the thunder raged, and it lasted for half a pillar of incense, and the original silver body of the Thunder Swallowing Heavenly Lion was full of scorched black bloodstains, and the mighty and huge body was bombarded at this time, and he raised his huge head to look at the rolling thundercloud, and there was more fear in the beast's pupils.

Above the sky, although the black thunderclouds were spinning wildly, the original roaring sound that resounded through the sky and the earth became inaudible, and the thunderclouds were becoming more and more tight.

"The tribulation was successful?" Gu Yan was slightly stunned, then turned his head to look at Xiao Jiu, who had turned into a human form, and said suspiciously. Xiao Jiu is a demon beast, and in this kind of matter, he obviously has more right to speak.

"It's early, now is the real thunder tribulation, and it's three!" Xiao Jiu's face was solemn, and it could feel what a terrible storm of destruction would be after that brief silence.

"Three Thunder Tribulations?"

Xiao Jiu nodded solemnly, looked at the thunder power that even it was a little palpitating, and said slowly: "Didn't you notice, this guy is crossing the thunder tribulation of the Three Seals Rebirth Realm!"

The rebirth realm, a total of nine seals, every time the tribulation, will usher in the power of rebirth, so repeatedly, its strength has doubled and skyrocketed, and now this thunder-swallowing heavenly lion has reached the level of the three seals rebirth realm!

Sure enough, the thundercloud tightened more and more, and finally seemed to reach a certain extreme, and after the silence, the terrifying power of the thunder suddenly unleashed, and a huge pitch-black thunder roared out like an angry dragon, and slammed into the giant beast on the top of the mountain.

The thunder pierced through the heavens and the earth, and in an instant, it slammed into the thunder-swallowing heavenly lion whose body trembled slightly.

Rumble!

The terrifying power directly struck the tall and mighty Thunder-Swallowing Heavenly Lion with a scream, and the thunder raged, cracking the scales on the giant beast's body alive, and blood gushed out, but it was a scorched black color.

Thundered!

Not long after the first thunder fell, before the Thunder Devouring Heavenly Lion could come to his senses, the second thunder roared again, and this time it was undoubtedly more powerful than the previous thunder.

Boom!

The terrifying power actually lifted the huge body of the Thunder Devouring Heavenly Lion more than ten zhang away, and hit the stone wall on the top of the mountain, the rock wall collapsed, and its breath became more and more sluggish.

"Is this the power of the thunder of heaven and earth, it's really terrifying!" Gu Yan muttered as he looked at the wolf who was overwhelmed by the thunder and swallowed the thunder. The thunder that is full of the coercion of heaven and earth is like a trial born between heaven and earth, and if you want to gain strength, you must survive it.

Thundered!

The somewhat unsightly Thunder-Swallowing Lion, which had been bombarded by the previous two thunderbolts, had just stood up from the pile of rocks, and the third thunderbolt had already crossed the sky and roared.

The thunder exploded, and an indescribably powerful thunder force swept away in an instant, the first of which was the mountain where the Thunder Devouring Lion was located, which was directly shattered by the violent force, and it also screamed in extreme pain, falling from the top of the mountain along with the broken boulder and blood.

Even from such a distance, the ancient proverb could still feel the ruinous breath that came to his face, and immediately sacrificed the blood seal in front of him, which could withstand the raging thunder.

The violent thunder was vented, I don't know how long it lasted, but the ancient proverb did not take back the blood mark of the common people, he knew that this kind of thunder power, any small wisp, was enough to blast him into nothingness in the Chaos Realm.

"Wu'er, stay here and don't move!"

When the raging thunder dissipated, Gu Yan hurriedly flashed to Xiao Jiu's head, looked at the girl with a dignified face, and said urgently. Then he rode Xiao Jiu, dodging those terrible impacts, and swept towards the direction of the Thunder-Swallowing Heavenly Lion.

The mountain peak collapsed, and in the center of the collapse, the dust was filled, and the smoke and dust slowly dispersed, and the scene in it was also seen clearly by the ancient proverb.

In that huge and incomparably deep pit, the thunder-swallowing heavenly lion wolf bèi lay on its stomach, its breath was sluggish, the silver scales on its body, large pieces fell, no longer had the same majesty as before, one after another hideous wounds were exposed on its body, and blood flowed out, dyeing the land red in an instant.

"Look at this situation, it's a failure of the tribulation!" Gu Yan rode Xiao Jiu, looked at the messy scene below, and said in a deep voice.

"Well, but with the blessing of the power of rebirth, as long as this guy can survive, coupled with the power of the beast, it won't be long before he can make a comeback and usher in the thunder tribulation again!"

"In other words, this guy shouldn't be too threatening in a short period of time, it's cheap for me!" Gu Yan clenched his fists, looking at the Thunder Swallowing Heavenly Lion with a sluggish breath below, and a crazy voice quietly came out.
