What Yi Han took out was the Jade Spirit Divine Spring Water, and for this kind of divine object unique to the Evil Ghost Ridge, except for the people near the Evil Ghost Ridge, few people in the entire Tiannan Continent knew about it.

Although Ao Yu has a natural keen sense of heaven and earth, he does not know its origin.

Hearing Yi Han say this, her heart was also shocked.

Brush!

When Yi Han uncorked the bottle, a more refreshing and holy aura suddenly filled the air.

"What pure spiritual power!"

Ao Yu felt the spiritual power coming from the bottle, and couldn't help but marvel in his heart.

Yi Han didn't hesitate too much, and after pulling out the cork, he immediately made a finger move, and a drop of spiritual liquid flew out in an instant.

Ding dong...!

When Yi Han lowered the jade spirit divine spring water on his fingertips on top of the fire spirit dao lotus, an extremely dazzling brilliance suddenly emanated from the entire dao lotus.

Airplanes......

The petals also fluttered slightly, but showed no signs of flowering immediately.

Seeing this, Yi Han was not surprised, and once again sacrificed a drop of divine spring water, which fell on the Fire Spirit Dao Lotus.

Ding dong...!

Brush!

Another flash of brilliance, Dao Lian still did not bloom.

Ding dong...!

Ding dong...!

Airplanes......

It wasn't until Yi Han used four drops of Jade Spirit Divine Spring Water that a burst of brilliant light bloomed on the entire Fire Spirit Dao Lotus, illuminating the entire cave even brighter.

As a buzzing sound came out, Yi Han and Ao Yu both saw that the lotus flowers were slowly blooming.

"It's mature! Hehe, that's great!"

When Ao Yu saw this situation, his face suddenly couldn't help but be happy, and he cried out in surprise.

"Alright, hurry up and refine it. I'll see how you turn into a dragon. ”

Yi Han had already put away the Jade Spirit Divine Spring and immediately urged.

"Well, good!"

When Ao Yu heard Yi Han say this, he couldn't wait for a long time, and immediately exuded a strange luster on his body.

Seeing this, Yi Han's figure flashed and withdrew from the range where Ao Yu was.

Brush!

Just as Yi Han had just retreated, he saw an extremely brilliant and gorgeous cyclone faintly born in the Fire Spirit Dao Lotus.

Then he saw that Ao Yu was like a dragon sucking water, and sucked the cyclone into his mouth. Suddenly, between its mouth and the Fire Spirit Dao Lotus, a tornado-like air flow was generated.

As Ao Yu inhaled more and more spiritual power, the original red and shiny luster on the Fire Spirit Dao Lotus also became more and more dim.

Brush!

At this moment, Yi Han only felt that the spiritual power in Ao Yu's body was becoming more and more majestic, and it seemed that there were faint signs of a breakthrough.

Bang......

At this moment, an earth-shattering thunderclap suddenly came from above the head.

When Yi Han heard this sound, he immediately reacted, and understood that this was Ao Yu about to turn into a dragon, and a cloud of calamity had formed in the sky, and there was about to be a thunderbolt in the sky.

Ao Yu's speed of absorbing the spiritual power of the Fire Spirit Dao Lotus was very fast, and after about a minute or two, the originally red and bright Fire Spirit Dao Lotus had begun to wither.

Brush!

Rumble!

Just when the Fire Spirit Dao Lotus was completely withered, an extremely terrifying thunderbolt suddenly fell from the sky.

When Yi Han heard this roaring sound, he suddenly felt bad in his heart. He didn't expect Ao Yu's breakthrough to make such a big move, and the power of the heavenly thunder had already exceeded his expectations.

"I'll go, this is too fierce, Xiaoyu, can she resist?"

Yi Han was thinking like this, when he saw that a thunderbolt had already hit Ao Yu's huge head through the top rock wall.

Roar!

Ao Yu, the fire crystal Jiao Aoyu, who was struck by the thunder that day, suddenly let out a deafening roar. Then Yi Han saw that his whole body was covered with purple lightning arcs, and his entire huge body was under electric shock, constantly trembling violently.

Thorn ......

Thorn ......

At this time, above his body, there was a constant crackling sound.

Ao Yu's face obviously showed a look of extreme pain, Yi Han couldn't help but be even more worried when he saw this, and couldn't help but want to set up a protective array around him.

"No... I have to withstand this thunderstorm, or I won't be able to completely turn into a dragon!"

Ao Yu seemed to sense that Yi Han seemed to move, and immediately endured the endless pain on his body and said loudly.

"It's... How so?"

When Yi Han saw the other party's painful look, he was very unbearable, and his heart was full of doubts.

Thorn ......

Time passed little by little, and the thunder and lightning on Ao Yu's body finally weakened.

At this moment, Yi Han suddenly found that bursts of white smoke were emitted from his body, which had enveloped most of his body.

Although the smoke was very thick, Yi Han still used his divine sense to see that under the smoke, more scales had grown on the surface of Ao Yu's body, and compared to the scales he had seen before, they were even shinier and the texture was more solid.

Seeing this, Yi Han's eyes suddenly flashed, and his heart was also overjoyed.

"Sure enough, there's changed! She's going to turn into a dragon!"

Sting!

Rumble!

Just as the thunder arc on Ao Yu's body completely disappeared, the second heavenly thunder immediately fell again.

Oh!

This time, Ao Yu raised his head to the sky and roared, and his voice was even more miserable than the first one.

Yi Han's heart couldn't help but twitch when he heard this, and a solemn look appeared on his face again, and his heart was even more worried.

Thorn ......

"Whew...!"

As the thunder and lightning on Ao Yu's body flickered, bursts of wailing continued to come out of his mouth.

"Come on, you must hold on!"

When Yi Han saw this situation, the worry in his eyes was even worse, and he silently cheered for Ao Yu in his heart.

Seeing the other party in such pain, Yi Han felt very uncomfortable in his heart, and he hated to bear some harm for him. But at the moment he couldn't do anything.

But fortunately, when those thunderbolts flashed, Ao Yu's body continued to change, and the dragon scales on his body grew more and more, and his body slowly became larger.

Soon, Ao Yu's size expanded by four or five circles. Yi Han also had to continue to retreat, and at this moment, this area in the cave was almost occupied by his huge body.

Click......

On the surrounding rock wall, there are constantly broken stones, all of which are caused by Ao Yu's body size and friction against the nearby rock wall.

Thorn ......

Soon, Yi Han saw that the innermost area of this cave was completely shrouded in white smoke, and he couldn't see the situation of Ao Yu inside, and he could see that thunder arcs were constantly flashing out.

Ao Yu no longer hissed at this time, and was obviously able to withstand the power of thunder and lightning at this moment.

Sting!

Sting!

As the sound of thunder and lightning flashing became smaller and smaller, Ao Yu's long body in the smoke was completely covered by a layer of white dragon scales. On top of her huge head, the horns of her hands also bulged.

Sting!

Rumble!

As the last bit of thunder arc disappeared, a third heavenly thunder fell in an instant!

However, when Yi Han felt this third thunderbolt falling, his face changed instantly, and he could no longer calm down.

"What a terrible thunderstorm! Can Xiaoyu handle it?"

After feeling this thunder and lightning, Yi Han's mind immediately turned sharply, at this time he couldn't bear it anymore, and he was already planning to help Ao Yu survive this thunder tribulation.

Roar!

Oh!

Click......

When the third thunder tribulation fell, Ao Yu let out a terrible howl, and his voice had already changed its tone.

Thorn .....

She screamed, and there was no movement. Seeing this, Yi Han's divine sense was immediately released, and he leaned into the billowing smoke and dust, and then his face immediately became gloomy!

"Oh no! Why are all the dragon scales shattered on her body, and the horns have fallen off! This is definitely not something she can bear!"

Yi Han thought of this, how could he continue to be indifferent. Immediately, with the flipping of his palm, the Jade Spirit Divine Spring was sacrificed again.

After uncorking the bottle, Yi Han didn't care about the thirty-seven twenty-one, and immediately poured out into the white smoke.

Yi Han didn't know how much Jade Spirit Divine Spring he had spilled this time, but he felt that the porcelain vase, which was still heavy, had become much lighter at the moment.

Crash!

The shimmering jade spirit spring water was not wasted at all, and it was all poured on Ao Yu's huge body.

It was also when the Jade Spirit Divine Spring touched Ao Yu's body that something magical happened.

I saw that the liquid did not splash, but in the blink of an eye, it did not enter Ao Yu's body.

Brush!

At this moment, ten thousand dazzling lights suddenly shot out from the billowing white smoke. In an instant, the entire Dark River Cave was illuminated!

Even Yi Han couldn't help but cover his eyes, it was really too dazzling this light.

Airplanes......

At this moment, an extremely piercing buzzing sound suddenly sounded in the cave!
