Shi Dong tracked Lei Hao all the way, although he was not as fast as the other party's rolling dragon, but the momentum of the rolling dragon was huge, and the smoke filled the place he passed, so he could barely keep up with the wind charm.

The two chased one after the other, traversing the entire first layer from west to east, and after about a meal, suddenly Lei Hao's figure disappeared into a mountain col.

"Bastard, this damn little rooster, where did he hide?" Shi Dong scolded in his heart, searching carefully while calming his guard.

Suddenly, he felt a strange mana fluctuation around him, which seemed to be a teleportation circle, and secretly wondered, he still carefully probed out his divine thoughts and searched, and found that in the depths of the mountain col, there was actually a teleportation circle that was extremely hidden.

"Strange, how can there be a teleportation circle here?" he touched his nose and looked at it, and saw that this teleportation circle was not large, only three feet in diameter, and it seemed that it was only enough for a few people to teleport through.

Although he didn't know where this teleportation circle led, as soon as he remembered that Lei Hao had seriously injured Mao Feifei and captured Zhu Ke'er, Shi Dong's heart was furious, and he couldn't wait to catch Lei Hao in front of him and slap him seventeen or eighteen times.

"Little rooster, no matter how far you escape to the ends of the earth, I will also catch you and cut you with a thousand knives to avenge my eldest brother!" Shi Dong was secretly ruthless, and the next moment he stepped on the teleportation circle without hesitation......

Shi Dong woke up from his dizziness, couldn't help shaking his head, and looked around in a defensive posture, and couldn't help but be startled.

I saw that the ghost aura in this place was even thicker, and there were actually several huge rock ghosts floating around. All of them are at the ninth level of the ghost soldiers. And a ghost head fell off. The other arm was lost. Seeing that the wound was smooth and smooth, it seemed to have been split by a sharp blade, which made Shi Dong immediately think that he was probably cut open with a golden light broadsword when he was broken by Lei Hao.

These ghosts were going berserk and furious, and as soon as they saw the stone move coming out, they immediately pounced on them with a strange roar.

Shi Dong had a serious loss of true qi at this time, but he didn't dare to fight hard, so he hurriedly threw out a fireball technique. Taking advantage of the fireball exploding on the rock ghost's face, he shook off the black cloak and draped it onto his body, and then used the breathing technique, and instantly his aura dropped to almost nothing, which suddenly made the rock ghosts who were screaming in anger lose their purpose.

Quietly dodging these fierce ghosts, Shi Dong made a careful investigation of the surroundings, and found that a thick trace like a rolling dragon crawling appeared on the ground, leading to the north, and the surrounding terrain was treacherous, full of fierce ghosts, and surging ghosts.

"Could it be the second layer of the Extreme Yin Cave here?" Shi Dong suddenly had a bad feeling. But he had to kill Lei Hao at this time, so he had to break into the Longtan Tiger's Den.

So he avoided the manic ghosts. took out the fire refining blood nourishing wine and drank a big sip, secretly exercised in the dantian, absorbed the true qi, and then let the light spirit ghost bless himself with a light spirit technique, plus the wind control talisman, and chased down the traces on the ground like flying.

Along the way, the breadth of the area is much larger than the first layer of the Extreme Yin Cave, and the level of the powerful ghosts is also one layer higher, and the fierce ghosts encountered are all ghost soldiers level ten, fortunately, the stone movement's breathing technique and the black cloak work very well, and no powerful ghosts have found him.

In the end, he found a teleportation circle in a hidden col, Shi Dong gritted his teeth, stood on it again, and was immediately teleported to another space.

When he woke up from his dizziness and saw that the ghost aura around him was even stronger, and the level of the ghost had also risen from the tenth level of the ghost soldier to the eleventh level, which made him frightened, and he also realized that he had come to the third layer of the Extreme Yin Cave.

Now that he has come to this point, Shi Dong turned his heart sideways, but wanted to see what Lei Hao was going to do all the way down, so he followed the traces of the rolling dragon and chased it all the way.

At this time, his true qi had already recovered to the third layer, and while he was cautiously hurrying, he pondered Lei Hao's intentions.

The previous blow, Shi Dong was completely sure that Lei Hao had been seriously injured, otherwise he would not have held Zhu Keer hostage and fled for his life in a hurry, with Shi Dong's understanding of him, as long as he still had the strength to fight, he would fight with his head up and his chest up.

Lei Hao kidnapped Zhu Ke'er and fled, indicating that if he stayed, he would be in danger of dying!

But why did he run under the Polar Shadow Cave? Could it be that he had been prepared? Or was it another conspiracy?

Shi Dong immediately thought of the chapter mouse who had not shown up, and when he asked the captured monk before, he learned that the chapter mouse didn't seem to show up on the first layer at all, which made Shi Dong have a bad premonition, it seems that as soon as the chapter mouse entered the secret realm, he went directly to the lower layer of the extreme yin cave, as if he had another plan.

"Zhang Mouse is only the twelfth layer of Qi refining, how can he have the courage and method to enter the bottom of the Extreme Yin Cave? Could it be that he ...... Who is there to show him the way?" Shi Dong thought of this, and a flash of lightning flashed in his heart, and a figure suddenly jumped out of his mind.

"Bai Jin! By the way, it must be him! It was he who guided Zhang Mouse down, and Lei Hao! It must also be related to this conspiracy!" As soon as this thought came out, Shi Dong's heart was shocked, and he hesitated for a while, feeling that if he continued to chase down, as if something terrible had happened.

He stopped, squinted his eyes and thought about it, and through the heavy fog rolling in front of him, he seemed to see Bai Jin standing high in the sky with a sinister smile on the corner of his mouth, his eyes projected playfully......

After a while, Shi Dong took a deep breath before recovering from his contemplation and exclaimed, "It's bad! Lei Hao turned the world upside down above, it must be for the conspiracy below! If the disciples can't get out in time, the longer the time drags on, the more beneficial it will be to Zhang Mouse! He must be doing some insidious thing down there! Should he go and take a look, or go out in time to tell the master?"

Although Lei Hao may be seriously injured, but that chapter of the rat is the twelfth layer of qi refining, even if Shi Dong is in the best state, he may not be able to beat, not to mention that the two of them are still working together, and there are even some hidden hole cards below, Shi Dong hesitated for a while.

"Could it be...... Can't the revenge of the eldest brother be avenged this time?"

He remembered that when the golden light hit his body, Mao Feifei desperately pounced on him, and used his back to block the killing attack for himself.

He remembered what Mao Feifei said when he was in the first year of entry, after he killed someone for the first time, he put his arm around his shoulder

"Brother Xian, don't worry, if someone uses a knife with you in the future, I will block it for you! If one day, we have to fight to the death, I ...... I'd rather cut out my heart with a knife than attack you!"

"Why?"

"Because, you're my brother!"

......

Quack!

Shi Dong's fists clenched tightly, his eyes suddenly became bright, something flickered in his eyes, and at the same time, his whole body exuded an infinite murderous aura.

"Big brother, your revenge, brother will definitely avenge you! Even if you go to hell, you will avenge it!" he strode forward, his body turned into a black smoke, and he went straight ahead.
