Although I don't know what the secret method in Xiao Du's mouth is, since Xiao Du said this, Gu Yi will inevitably choose to believe Xiao Du.

Gu Yi knew that Xiao Du's stunt would not joke with his life, although Gu Yi believed in Xiao Du, but Gu Yi had to prepare for the worst, his eyes were fixed on everything in the field, as long as there was a slight change, Gu Yi would rush into it without hesitation and rescue Xiao Du.

As for doubling the power of the thunder at that time, Gu Yi couldn't care so much.

The inky golden thunder and lightning in the sky are constantly pregnant, from the thickness of the bucket at the beginning to the thickness of the water tank now, and it is still changing, slowly absorbing the power of thunder and lightning in the clouds.

Xiao Du's face in the field is also very serious, if this thunder is only the thickness of the bucket at the beginning, Xiao Du is still completely sure, but now... Xiao Du shook his head helplessly, he was not completely sure that he would be able to resist this thunderstorm.

"Boom, boom!" The thunder in the sky was constantly rolling, and there were tiny, snake-like thunderbolts rolling in the clouds.

Finally, half an hour later, there was no thunder and lightning rolling in the clouds, but at this time, the clouds were as big as three large water tanks.

Seeing this thunderstorm, Gu Yi really gasped, and at this moment he really had the urge to rush into the clouds to help Xiao Du desperately.

But looking at Xiao Du's firm eyes, Gu Yi endured it vigorously, and at this moment Gu Yi still chose to believe in Xiao Du.

"Hiss !!" A high-pitched groan suddenly roared out of Xiao Du's mouth, shaking his wings, Xiao Du did not retreat but advanced, and instantly rushed into the clouds.

At the moment when Xiao Du rushed into the clouds, Gu Yi clearly saw that the ink-gold robbery thunder with the thickness of three water tanks turned into a black-gold python, wrapped around Xiao Du's body, and bit Xiao Du together.

Looking at the Mojin Lei Tribulation and Xiao Du who were entangled together, Gu Yi's palms unconsciously clenched together, closely observing all the changes in the tribulation clouds.

Just when Gu Yi was shocked and stared at the clouds with all his might, the giant python transformed by the thunder tribulation suddenly twisted and spasmed, and at the same time, a violent roar exploded...... "Roar!"

There is endless pain, anger, sorrow, and anxiety in this roar......

"Bang, bang, bang!"

The next moment, there was a huge earthquake in the canyon that shook the ground and shook the mountains, and the sound of landslides and tsunamis was like two behemoths, fighting with all their might!

The giant python phantom in the sky and Xiao Du's Benti kept trembling together, the scene was terrifying, and the two sides trembled and spasmed more and more, and the amplitude became bigger and bigger!

At this moment, Gu Yi had a feeling that Xiao Du was not fighting with the clouds, but two ancient beasts were fighting, and the battle was so fierce that Gu Yi gasped deeply.

Gradually, Gu Yi found that Xiao Du slowly gained the upper hand, and Gu Yi was really relieved.

At this time, the inky golden thunder and lightning that was wrapped around the giant python turned into a thunderstorm were being torn apart by Xiao Du one by one, breaking away from the body of the giant python, and being stuffed into Xiao Du's mouth indiscriminately, or inhaled deeply into the nostrils!

At the same time, the single horn on Xiao Du's huge horse's head is slowly falling off, and the thunder in the sky that has turned into a giant python is slowly changing from the thickness of the three water tanks at the beginning, and now it is only the thickness of two water tanks, all because his whole body strength is the source of Mo Jinlei being swallowed by Xiao Du.

Seeing this, Gu Yi secretly praised the powerful and perverted, he was able to devour the thunder, and it was such a powerful thunderstorm.

"Wooh!"

At this time, the thunder python seemed to have emotional intelligence, and let out a complex roar that confused helplessness, pain, and anger.

"Groan!"

And Xiao Du is also roaring wildly, hissing, surprise, and joy are the majority!

"Bang, bang, bang!"

Xiao Du suddenly slammed into a violent blow, his fists fell like raindrops, and each punch smashed the thunder python, and after the silver snake-like ink gold thunder fell off, it was swallowed by Xiao Du.

"Woooooo

After devouring these silver snake-like inky golden thunderbolts, the single horn on Xiao Du's forehead finally fell off and fell to the ground.

In the past, Xiao Du looked full of nobility and wonder because of the single horn on his forehead, but now after Xiao Du's single horn falls off, it looks weird for a while, but no matter how Xiao Du is, he is Xiao Du, and he is my brother in Guyi, and this will not change.

After the horn on the forehead finally fell off, Xiao Du's eyes finally showed a trace of excitement and expectation, and then Xiao Du rushed directly into the body of the giant python in the incredible gaze of Gu Yi, and actually bit the giant python like this, and began to "swallow" the giant python turned into a thunderbolt in one mouth.

With Xiao Du's devouring, the giant python roared weakly, but even if he was unwilling, he couldn't change the result, that is, destruction, at this time, the giant python was slowly dissipating, and the body, which was originally only the thickness of two water tanks, was also getting smaller at a speed that could be seen by the naked eye.

But these are not Gu Yi's concerns, because at this time Gu Yi's eyes were all attracted by Xiao Du, after absorbing the giant python turned into a thunderbolt, Xiao Du was originally because the original single horn fell off, and the empty forehead was growing a single horn at a speed that was visible to the naked eye.

In the past, Xiao Du's single horn had no other special role except for being able to use a trick to inherit the cold tide light from the big demon goshawk, but now Xiao Du's newly grown single horn gave him a rather dangerous feeling.

And this new unicorn has a deep cold light, and there are constantly ink-gold thunderbolts flickering, and this flashing ink-gold thunderbolt is even suspected to be converted by the thunder after being swallowed by Xiaodu, if this is the case, then its power can be imagined.

In less time, the giant python in the clouds completely disappeared in the thunderstorm under Gu Yi's shocked gaze, and with the disappearance of the thunderstorm, the clouds in the sky seemed to have lost its target all of a sudden, and slowly dissipated into the sky.

After a while, the canyon returned to the status quo of clear skies, if it weren't for the chaos in the canyon, who would have believed that there was a shocking demon who had survived the most difficult thunder tribulation in this place just now?

The moment the clouds dissipated, Xiao Du turned into the main body and instantly appeared beside Gu Yi, and Gu Yi didn't even notice the slightest spatial fluctuation.

"Big brother, now I'm a powerhouse in the Hell Realm!" As soon as he opened his mouth, Xiao Du began to sell well.

This made Gu Yi a little unbearable.
