Hearing Qian Chengming's shout, everyone agreed in unison, lined up to leave the city gate, and was led by Meng Tiandong to set off quickly towards the Yin Feng Cave.

Speechless all the way, Meng Tiandong seemed to be in a hurry, running as fast as he could.

At first, he thought that Zhang Yu's cultivation would not be able to keep up, and he was about to find an excuse to make fun of him, but he knew that Zhang Yu followed behind with ease, and he didn't fall a single step.

Seeing this, Meng Tiandong's pupils contracted, he couldn't imagine that Zhang Yu's talent was so good, and over time, his achievements would definitely be above him.

This kind of person is most suitable for strangulation in swaddling clothes, Meng Tiandong thought to himself, he didn't notice that the black qi inside his heart had expanded by a point.

"Hmph, suffocate me. Little Black came out and said, and before he could finish speaking, it suddenly sniffed the air, as if it had smelled something.

"What's wrong?"

"It's the smell of the ghost domain, so familiar!" Xiao Hei said solemnly.

"Could it be that Meng Tiandong?" Zhang Yu frowned and looked over, switched the eyes of ghosts and gods, and found that there was a cloud of black qi shrouded in Meng Tiandong's heart.

"Sure enough, this is a trap at all!" Lin Xueyue also came out and said angrily.

"Then what should I do? Why don't you come up with a plan?" Zhang Yu lowered his head and said, if he rashly told Qian Chengming, there would definitely be a trap here, and the best way was to let them think it was a trap, Zhang Yu told Xiao Hei and Lin Xueyue about this idea.

"Pretending to be a ghost domain person, this is no problem!" Xiao Hei licked his mouth and was very excited, it was from the ghost domain itself.

"Then when will it start?" Lin Xueyue was also very interested

"You go to reconnoiter in advance, and if you encounter the aura of the ghost realm, start ...... immediately," Zhang Yu stared at Meng Tiandong's back and said coldly.

After Zhang Yu gave the order, Xiao Hei and Lin Xueyue turned into black gas and disappeared in place.

"Stop advancing!" At this time, Qian Chengming suddenly shouted, and the whole team immediately stopped, skillfully put out a defensive formation, and looked around vigilantly, worthy of being the elite of the battle-hardened formation, Zhang Yu also saw a few disciples preparing to flow gold fire rain spells.

"Huh, is it an illusion?" Qian Chengming muttered, he clearly noticed a chill just now, as if something was passing by.

"Heavenly Eye!" He pinched the sword finger in his hand, and in an instant, a red light appeared on the sword finger, and the red light smeared on his eyes, and his pupils instantly flashed with golden light.

This is also a spell similar to the pupil technique, and he looked around but found nothing, could it be an illusion just now?

"Keep going!" Qian Chengming said loudly after removing the Tongtian Eye, his Tongtian Eye was not like the pupil technique of the Heavenly Master Clan, and it could be used at any time.

The team advanced again, and Zhang Yu secretly breathed a sigh of relief, fortunately Xiao Hei and Lin Xueyue ran fast, otherwise they would have been discovered.

Soon came to the Yin Feng Cave, and the team jumped into it under the leadership of Meng Tiandong.

"Where is Senior Brother Zhang?" asked Qian Chengming.

"Right in front of the cave, there is a huge rock next to the entrance that stands out. Meng Tiandong pointed to the dark place in front of him and said, fortunately, the cultivator's eyesight is much better than that of ordinary people, and he can see that there are many strange rocks here, and the darkness before him swallows up the light, the real darkness.

God knows what is hidden behind the darkness, Qian Chengming called everyone to be vigilant and ran forward.

"There is a strong ghost atmosphere here, it seems that there are a lot of people in the ghost domain!" At this moment, Xiao Hei's voice came.

When they came here one step earlier, in addition to feeling the many powerful biomes around them, they also hid the aura of the ghost people.

"How's it going?" asked Zhang Yu.

"Hmph, if nothing else, the end of that Zhang should also be a ghost domain person, I can feel a few ghost domain people scattered next to that big rock, ready to ambush. Xiao Hei continued.

"Then the action begins, you stay safe. Zhang Yu admonished.

As soon as he gave the order, Xiao Hei and Lin Xueyue immediately turned into a cloud of black gas, and then those black gases turned into several black cloaks, and quietly surrounded them.

"There is a situation! Tongtian Eye!" Qian Chengming was worthy of being an inner disciple, he was keenly aware of the changes around him, and he moved extremely fast.

"It's a ghost, no, it's a ghost domain person!" Qian Chengming was taken aback, the affairs of the ghost domain people were all clear to their inner disciples.

How could you meet someone from the Ghost Domain here, Qian Chengming's mind was churning, and he was not slow to react and shouted loudly: "Form a formation, 200 meters ahead, kill me!"

As soon as the words fell, he immediately pinched his handprint and said loudly: "Tongtian Eye, speed!"

Seeing a ray of light shining from his hand, turning into dozens of rays of light, flying into the eyebrows of each outer disciple, Zhang Yu felt that a light flashed in front of him, and he could vaguely see several black shadows fluttering not far in front of him.

It's too vague, it's not clear at all, bad review!

In fact, it would be good to be able to do this, many outer disciples saw the target, they reacted extremely quickly, and quickly formed a formation, and countless fireballs appeared out of thin air, flying towards those few black shadows.

The shadows couldn't dodge, and one of them was smashed into the body, instantly turning into a humanoid torch and disappearing into the air. This is still Xiao Hei's deliberate doing, otherwise the fireball will definitely not hit its clone.

As if frightened, the other black shadows retreated back in embarrassment.

"Kill them!" Qian Chengming shouted.

"Senior Brother Qian Chengming, wait, there is already a lot of danger here, and I don't know how many of those black shadows there are, why don't we let people go back first and report the situation here to Senior Brother Zhao?" At this time, Zhang Yu hurriedly persuaded beside him.

"Well, Senior Brother Zhang is reasonable, Wang Qi took the two of them back, reported the situation just now to Senior Brother Zhao, and asked him to send reinforcements over quickly. Qian Chengming was stunned, he nodded slightly, turned to a disciple and said.

"Yes!" Wang Qi said, calling the two of them to leave quickly.

"Let's go and see who they are. There are no worries, Qian Chengming said loudly. Seeing that Qian Chengming actually listened to Zhang Yu, Meng Tiandong's eyes flashed with ruthlessness.

"But what about Senior Brother Zhang?" he said, rolling his eyes.

"Isn't this just on the way?" Zhang Yu said with a smile on his face.

"Damn!" Meng Tiandong scolded in his heart, he was helpless, everyone continued to move forward, they were always on guard around.

On the cliff not far away, several dark shadows waited quietly, one of them suddenly Zhang Zhi, he looked at the dark crack with an expressionless face, as if his eyes would see clearly through the crack to the group of cultivators of the Dan Dao Sect.

If Meng Tiandong saw this, he would definitely be surprised, because he saw Zhang end poisoned and fell to the ground unable to move.

And Zhang Duan's plan was very simple, he wanted to occupy the corpses of these cultivators, open the spatial crack, and release more ghost domain people. It can take advantage of the right time, place and people to capture the Black Iron Castle in one fell swoop, and make the entire Spirit Stone Mine Cave an outpost of the Ghost Domain.

This idea was extremely tempting, but it was not easy to implement now, because the group of cultivators had obviously increased their vigilance, and it was much more difficult to kill them.

Zhang Duan had a plan, he watched the group of cultivators walk into the attack range, he couldn't help but stretch out his arm, a thick tumbling black gas appeared in his hand, he violently pressed this black gas to the ground, and roared in a low voice: "Ten thousand ghosts are out of the tomb!"
