Although there were only Chi Meng, seven or eight men in black, and the father and daughter in the center of the ground, there were actually countless dark shadows lurking around them.
However, the mission of these shadows is to be on guard, to ensure that the location of these people is absolutely safe and that outsiders do not know the situation.
"Are you sure it should be around here?" Chi You asked.
Shangguan Qinghai looked around and finally nodded: "The terrain to the north of the famous store is very complicated. It is surrounded by mountains and the outer wall of Burning Bone City."
"And there are many undercurrents here, which is very dangerous."
"However, the more complex the terrain is, the simpler the place is, at least compared to the target point we are looking for."
To dig a secret tunnel that is as deep as 50 meters, the surrounding terrain must at least be relatively flat and dry.
Otherwise, it will be difficult for you to dig down.
Based on this, you can basically exclude mountains and foothills, because there are too many dark rocks there that can easily block excavation.
Places with undercurrents and relatively humid conditions can basically be ruled out because the soil underneath is relatively humid. Although it is easy to dig, it is not conducive to the formation of tunnels.
After thinking about it over and over again, it is obvious that only relatively dry but relatively flat places are the best places to build tunnels.
"Our current place is equivalent to a small basin, located in the mountains. Therefore, if normal people want to choose, it is best to dig in the center of the basin."
"Moreover, the basin is not big, which makes it easy to hide."
Chi Meng nodded, basically fully agreeing with Shangguan Qinghai's view. He came to the current location and observed the surrounding terrain. If it were her, she would dig a tunnel here.
"Do you want to dig?" Shangguan Qinghai looked at Chi Meng.
Chi Meng didn't say anything. He glanced at a few of his subordinates. Several men in black immediately asked the father and daughter to leave. After that, they each released a beam of energy from their hands and slapped it directly on the ground.
The energy quickly covered the ground directly, and then the energy turned into a milky white stream and spread completely on the ground.
Chi Meng's eyes quickly scanned above, and after a moment, her eyes fell on a place not far away.
There, the milky white energy was obviously discolored.
Chi Meng's feet moved slightly and flew directly over. The group of men in black also collected their energy in time and followed closely.
The father and daughter also followed, but there seemed to be no other strange places on the ground after the milky white energy disappeared.
Here, it's just a mediocre meadow. The grass is long and lush, and the land is relatively flat. It doesn't look like an authentic entrance at all.
"Miss, you...do you suspect that this is the entrance?" Shangguan Qinghai asked doubtfully, "But it doesn't look like it."
The color of the excavated soil is naturally different from that of other places, but that was decades ago. In other words, after years of baptism, even if this is the case, it should be almost completely assimilated.
Unless someone has gone down to the tunnel and reopened it, only then can we see the newly opened land.
But in this place, the soil is solid and the grass is tough, unlike places that have been disturbed in recent years.
"It's not a suspicion, it's just here." Chi Meng said very firmly: "This is a unique secret method of ours. Previously, the color here has been abnormal, which means that the atmosphere below is different from other places.
"
"Unless someone deliberately buried a big rock underneath to disrupt our view."
This secret method can detect the soil density almost deep in the soil, and the detection depth is extremely deep.
As for why there is such a method, it is applied in such a place.
It's actually very simple, it's just fate.
Along the way, Lu Ruoxin could basically see what Han Sanqian had in store very clearly. Therefore, in order to deal with Han Sanqian hiding in the ground like before, he would use the obscene hiding method like the Book of the Eight Desolations.
, Lu Ruoxin sent people to study this technique early!
As a result, Han Sanqian hadn't used them yet, but now he was accidentally using them because he was looking for a tunnel.
