As Lin Tian waved his hand, a golden lightning flew out from his hand and hit the dragon hard. Then the dragon also let out a shrill scream.

"You can actually harness such terrifying power of thunder and lightning!"

When Zhu Jiuyin saw this, his face suddenly changed and he hurriedly retreated backwards, but the lightning did not stop, and several more golden lightning bolts blasted out.

Zhu Jiuyin tried his best to dodge the golden lightning, but his speed was too slow. Every time he dodged a lightning, there would always be a charred mark left on his body.

And he also exuded a faint smell of barbecue.

Seeing this scene, Zhu Jiuyin became even more angry, but his speed did not slow down, instead it became faster and faster.

"Damn it, don't be so complacent, kid!"

After saying that, Zhu Jiuyin turned into a ball of fire and rushed towards Lin Tian. This time, Zhu Jiuyin seemed like a different person, and his speed was frighteningly fast.

"Why did this guy's speed increase again? Is it because of the domain?"

Lin Tian was extremely shocked and dodged in a hurry, but his speed was not as fast as Zhu Jiuyin. He was caught by Zhu Jiuyin after just one second of dodging.

"Haha! Boy! Even if you have supernatural powers, you can't escape this time! You are dead!"

Zhu Jiuyin laughed loudly, and then planned to swallow Lin Tian into his stomach.

But Lin Tian was not panicked at all. With a wave of his hand, a brush appeared in his hand. It was Lin Tian’s natal magic weapon: Tianji Pen!

The Tianji Pen trembled slightly, emitting a dazzling green light, with golden lightning entwined around it.

The lightning and Zhu Jiuyin's bloody mouth collided, and a shocking roar suddenly broke out. The aftermath of the collision between the two destroyed the surrounding mountains.

"Can you withstand my attack?"

Seeing this scene, Zhu Jiuyin showed a puzzled expression on his face, but he quickly returned to normal, and then opened his bloody mouth again to spit out spiritual energy to attack.

A deafening roar resounded through the sky. Zhu Jiuyin only felt that his internal organs in his chest were shifting, and a mouthful of blood spurted out.

But Lin Tian was not hurt at all, and with a teasing smile on his face, he looked at Zhu Jiuyin and said lightly.

"Your strength is not enough, it's still far from enough!"

After saying that, Lin Tian raised the Tianji Pen in his hand again and drew a stroke at Zhu Jiuyin again.

A golden lightning suddenly appeared in front of Zhu Jiuyin, rushed straight towards it, and instantly hit its forehead, making a loud bang, and a golden flower appeared on its forehead.

Zhu Jiuyin let out a shrill scream and was knocked to the ground again.

"How dare you, little kid, hurt me? You are asking for your own death!"

Zhu Jiuyin roared and then pounced towards Lin Tian. His skin instantly turned gray, even his hair turned gray, and he even grew fangs.

Seeing this scene, Lin Tian sighed inwardly. This was because Zhu Jiuyin's aura had increased countless times after entering the violent period.

"Sure enough, it is invincible in its own domain. I have to find a way to break it."

Lin Tian thought secretly in his heart that the space around him had been confined and there was no way out at all.

"I am invincible in my domain. If I can devour three more people, I can reach the true realm of the gods!"

Zhu Jiuyin said this arrogantly, then opened his bloody mouth and bit towards Lin Tian again.

While Lin Tian was resisting Zhu Jiuyin's attack, he kept making hand gestures to offset Zhu Jiuyin's power.

Just like that, with Lin Tian's continuous attacks, Zhu Jiuyin's attacks became somewhat slow.

A quarter of an hour passed, and Zhu Jiuyin still hadn't won. Instead, his aura became much weaker.

Finally, as the final spell was completed, a gleam of light flashed in Lin Tian's eyes, and then he took a step forward and appeared above Zhu Jiuyin's head.

Lin Tian held the Tianji Pen and pointed it at him fiercely.

A golden sword energy appeared in the air. This sword energy contained the power of thunder. Once it was cut down, it would surely kill Zhu Jiuyin.

"Not good! There's something strange about this sword energy!"

Feeling the terrifying power, Zhu Jiuyin's face became extremely embarrassed, and he quickly turned around and ran away.

“Too late!”

Seeing this scene, Lin Tian raised his hand, and the sword energy appeared again, and its power was even stronger than before, and it chopped down at Zhu Jiuyin's head.

Zhu Jiuyin's body suddenly turned into a blood mist, and then turned into starlight and disappeared on the spot.

But Lin Tian did not relax, because he knew that Zhu Jiuyin would condense again and he had to destroy the domain.

Lin Tian swung the Tianji Pen in his hand suddenly, and suddenly a golden light blasted towards the smoke from top to bottom.

Wherever the golden light passed, all the smoke disappeared, and then the smoke turned into countless flames, burning.

Seeing this, Lin Tian's face lit up with joy. If he continued like this, he would definitely be able to break through the domain easily.

At this moment, the golden light disappeared again.

"No! We need a stronger attack!"

Thinking of this, Lin Tian raised the Tianji Pen in his hand again and waved it out with a golden lightning.

The power of this lightning increased again, and then it blasted towards the smoke, but was still blocked by an invisible barrier.

Seeing this scene, Lin Tian frowned slightly.

"What's going on? Is it a power suppression?"

Thinking of this, two golden rays of light suddenly shot out from Lin Tian's eyes, and then he took out another golden talisman paper, aimed it at the barrier and hit it hard.

The golden flame appeared again on the tip of the Tianji Pen, and Lin Tian then once again waved out the golden light and bombarded a point.

This time, Lin Tian’s attack was obviously more powerful. A violent roar was heard, and the golden light finally broke through the barrier.

And that golden light once again passed through the smoke and hit the mountain wall on the other side. The whole mountain shook, rocks rolled, and then the mountain collapsed.

"Great! It actually worked!"

Seeing this scene, Lin Tian was also very excited. Although it was only for a moment, this move also brought him huge gains.

Now that he has understood the magical effect of the Tianji Pen, he can use a secret technique called 'Wanxiang Tianyinshu', which allows him to use the power of the Tianji Pen to perform supreme skills in a short period of time!

Only the sound of breaking was heard, and Zhu Jiuyin's body fell to the ground, and at this time Lin Tian also returned to the outside world.
