The Four Spirit Sect was all too familiar with the Cangmang Mountain Mining Area, and the four of them quickly found the location of the gate between the high walls of the mining area.

Standing in the forest, with Tang Mian's eyesight, he could see the disciples of the Ice and Fire Sect patrolling the night in groups on the high wall of the mining area, as if they were in a wartime state of vigilance.

Under the vast night, there is a layer of looming light over the entire Cangmang Mountain, which is the light of the mountain protection array.

"This array is called the Five Elements Imperial Spirit Array, although it is not as good as the Four Spirit Array of my sect, it is also quite mysterious, and it cannot be broken by non-Jindan monks. ”

Huang Xue leaned against a big tree, clasped her hands in front of her chest and said lightly.

Zhao Quan nodded on the side, and then said to Tang Mian and Mi Zhen:

"This array is sturdy but unsurveillance, so we just need to sneak in when the big array opens and closes. ”

Tang Mian and Mi Zhen bowed slightly, they naturally knew what they wanted in their hearts.

According to the results of the previous discussion, Huang Xue, as the person who performed the soul search, must enter it. And Tang Mian, as a physical cultivator with the strength of the foundation building period, is obviously more convenient and flexible to move around in the enemy's camp.

"It's almost time, Tang Daoyou come with me. ”

Huang Xue pinched a magic trick in his hand, Tang Mian only felt a strange feeling coming from his body, and then found that he was one with the night and became transparent.

Huang Xue, who was originally in front of him, also disappeared immediately, and when Tang Mian was stunned, the crisp and pleasant voice of the former came from the sea of knowledge.

"This is a concealment technique that can only be performed during the foundation building period, and if the strength of the divine consciousness does not reach the middle stage of foundation building, there is absolutely no possibility of detecting it. ”

Tang Mian bowed slightly when he heard this, and the methods of the cultivators in the foundation building period of the heart path were really mysterious.

The two of them slowly approached the large array of the mining area under the eyes of Mi Zhen and Zhao Quan, and under the double blessing of the concealment technique and the breathing technique, the two of them seemed to be non-existent.

"The gate is heavily guarded, and we need to be on the right foot. ”

After all, Huang Xue is a genuine foundation building period monk, and she is quite proficient in formation, while although Tang Mian claims to be a physical cultivator with the strength of the foundation building period, she is a qi refining stage monk after all, so she subconsciously took on the role of team leader.

Of course, Tang Mian didn't have any opinions on this, just follow the other party and act carefully.

The two of them approached the big formation little by little, and behind the light was a ten-meter-high city wall. Every once in a while, monks would walk over the walls in groups.

"In about half an hour, a team of men and horses carrying ore will go out from this place, and we will just wait. ”

Huang Xue said to Tang Mian.

Next, the two of them hid in the darkness for some time, and then they saw the gate under the city wall slowly open, revealing the mining area inside.

At this moment, Tang Mian and Huang Xue felt several divine senses swept over from the vicinity at the same time, obviously the disciples of the Ice and Fire Sect were probing. However, because of the existence of the concealment technique, Tang Mian and the others were not discovered.

After several divine senses swept over, Tang Mian found that the nearby light began to slowly become thin, and the light at the gate of the city wall disappeared little by little, finally revealing a gap the size of the city gate.

Immediately afterwards, a convoy full of ore drove out of the mining area, and it was a certain spirit beast raised by the Ice and Fire Sect.

After Huang Xue and Tang Mian glanced at each other, they immediately cast a magic trick and floated towards the city gate. Tang Mian followed closely behind him, secretly holding the Golden Earth Array in his hand, and dealing with the danger that would come at any time on time.

Huang Xue looks like a beautiful fairy on the outside, but she acts very decisively and spicy, and her beautiful face shows strong confidence.

The convoy was carrying Shen Iron Ore, which Tang Mian was all too familiar with, and there were about five or six Ice and Fire Sect disciples in charge of transporting it, and there were many people on the city wall who were routinely monitoring below.

Huang Xue's movements did not pause in the slightest, she walked towards the convoy, passing by the city gate, and the expression on her face did not change significantly from beginning to end.

As he passed through the city gate, Tang Mian clearly felt that an extremely strong divine sense passed from above, which obviously belonged to the monks of the foundation building period.

"If it were the mid-to-late stage monks here, I'm afraid we would have already shown our feet. ”

Tang Mian followed Huang Xue and floated directly into the mining area, and the gate behind him slowly closed at this time, and then even the gust of light was completely closed.

Judging from the investigation information of Huang Xue and Zhao Quan, the iron ore excavated in the mining area was actually transported to the vicinity of Yancheng, where the iron was smelted.

Therefore, the time for the transport convoy to go back and forth is not long, and during this time, Tang Mian and Huang Xue must complete the task, otherwise it is inevitable that something will happen.

Huang Xue, who has the divine sense of the middle stage of foundation building, uses the concealment technique, and at most can avoid the detection of the middle stage monks. But there may be late-stage or pseudo-Dan stage cultivators, which makes Tang Mian and Huang Xue have to speed up.

Since it was night and the miners and mortal deacons were resting, the mining area was unusually empty and quiet.

The layout of the Cangmangshan mining area today is very different from before, even if Tang Mian has been locked up here for a year, but today it is like the first time he has come.

Because she couldn't use her divine sense, Huang Xue could only search for the information she needed with her naked eyes, and the endless mining area made her a little clueless.

"I can see scattered buildings in that direction, can I look for it there?"

Tang Mian said factually.

After taking the spirit fruit, Tang Mian's eyesight has been greatly improved compared to ordinary people, and he can always be used in the dark night.

Huang Xue looked at Tang Mian with some surprise, and then said:

"Then go and see, no mortal will live halfway up the mountain. ”

In less than a stick of incense, the two rushed to the mountainside of the mining area. From this place, you can clearly see the scattered pavilions, and the environment here is very different from the mining area at the foot of the mountain.

Huang Xue nodded to Tang Mian on the side, and said softly:

"Looks like you've found the right place. ”
