Just when Mu Weiyang was stunned, Grandpa Fei and the others had already walked in front of her.

"Are you alright?"

Seeing Mu Weiyang standing aside in a daze, the bark face walked over.

Mu Weiyang looked at the bark face and said, "Are you all right?" ”

Bark Face shook his head confidently: "Who dares to approach the Fei family, isn't this looking for death...... Uh, Dad. ”

The bark face was just about to brag about it when he saw Grandpa Fei's gloomy face.

"Don't talk nonsense, get out of here first."

Grandpa Fei's words made the bark face instantly put away that giggling look, and followed Grandpa Fei in front of him towards the place where Gongsun Libo disappeared before.

It was only at this time that Mu Weiyang, who was following behind the bark face, understood that there were two trees standing side by side here, and the diameter of the trees was nearly one meter, which could completely block an adult man.

One of the trees next to the rocks had a half-human-high tree hole, and there were many vines in front of this tree hole, and Gongsun Libo had just gotten into this tree hole.

Because of the tree in front of him, it looked as if he had disappeared out of thin air as he walked through it.

Now the bark face lifted the vines in front of the tree hole for Mu Weiyang, and Mu Weiyang saw the existence of this tree hole, so he followed it.

After entering the tree hole, Mu Weiyang had to hunch over and walk a few steps, and as the space behind the tree hole gradually expanded, she was able to straighten up.

At this time, Grandpa Fei, who was walking in front of Mu Weiyang, was still hunched and walking because he was taller than Mu Weiyang.

The space behind the tree hole was dark and damp, and if it weren't for someone leading the way, Mu Weiyang would even doubt that this road could really lead to the outside.

Everything around her couldn't see clearly, so she could only rely on her sense of touch to follow Grandpa Fei, who was hunched, and meandered forward with her hands touching the top of her head and the walls on both sides.

From the tactile point of view, the surrounding walls are said to be walls, but they are more like the touch of a natural cave, Mu Weiyang did not feel how many artificial traces there were behind this tree hole, or rather, even if it was artificial traces, it had been weathered and integrated with nature in the corrosion of the years.

After walking for another while, Mu Weiyang felt as if he had stepped on a lot of small stones, and there was a rustling sound under his feet.

The rustling sound lasted for about half a pillar of incense, and Mu Weiyang only felt that the surroundings were empty, and they seemed to have entered a relatively large space.

At this time, Mu Weiyang could only hear a crisp sound of "click".

A flash of blue light in front of my eyes.

Gongsun Libo, who was the first to enter here, didn't know what he interrupted, and sprinkled blue light all over the ground, emitting a rotten fish smell.

Under the glow of these blue lights, Mu Weiyang, who had been in the dark for a long time, finally saw this place clearly.

There were eight people standing in a space that could fit about four tables.

Gongsun Libo and the four of them stood in front of Mu Weiyang, Grandpa Fei, and Bark Face, and when he saw Mu Weiyang looking around, he explained: "This is a phosphorus fire extracted from a rotting corpse, which can be ignited directly and will not cause a fire, so it is most suitable for use in this kind of place." ”

Mu Weiyang looked around and nodded, it seems that this is also a secret room transformed from a natural cave, and there are still flammable objects such as intertwined roots and leaves around it.

Gongsun Libo saw Mu Weiyang looking at the other passage behind him, so he smiled and said, "Keep going here, about half a day's trip, you can go directly to Qi Mu." ”

After Gongsun Libo's words were finished, Mu Weiyang was stunned for a moment, turned his head to look at Grandpa Fei, and then looked at Gongsun Libo, and asked, "Is there such a secret passage between Qi Mu and Yaogu?" ”

Grandpa Fei and Gongsun Libo nodded at the same time, and Grandpa Fei spoke first: "I have already told her about her life experience." ”

Gongsun Libo showed a clear look, and then said: "Since you already know your background, then I don't need to explain it from the beginning. Since you know your background, you naturally know that Qi Mu relied on the 'thief way' to become the ruling power of the five great powers in the past. ”

Mu Weiyang nodded, recalling the real history of Qi Mu that Grandpa Fei told her before, the origin of the "Prohibition Period".

Seeing Mu Weiyang nodding, Gongsun Libo continued: "Although we have relied on the 'thief way' to rule the five major countries, we don't want this matter to be put on the surface. Therefore, in order to facilitate the 'Mujia' tonic medicine, a hundred years ago, with the help of the 'Tujia's acupoint, this tunnel was built to lead directly to the medicine valley. But as time passed, the tunnel, which could have been used for a single cart, was pressed lower and lower by the rocks, and finally became what it is now. ”

"So, this was originally a transportation route built in the belly of the mountain for Qi Mu to transport potions?"

Gongsun Libo nodded and said, "This place is located in the northeast of the Medicine Valley, if there is no obstruction from this mountain, it can lead directly to Qi Mu." But it is precisely because of the obstruction of this mountain that many people ignore that the straight-line distance between this place and Qimu is actually not far. Isn't this a great hidden transport route? ”

After listening to Gongsun Libo's words, Mu Weiyang drew a map in his mind:

The medicine valley is located in the north of Qiangzheng and the west of Qimu, and does not intersect with Hanyan in the southeast of Qiangzheng and Qimu.

From Qiangzheng to Yaogu, you can go directly from the official road, and if you go from Qimu to Yaogu, you need to detour to the southwest official road, or turn to the official road that connects with Qiangzheng.

But in fact, there is another route, that is, from Qimu over the mountain.

However, since there are no cars to cross this route, it has to be walked on foot, so almost no one chooses to go over the mountain.

But without this mountain, the distance between Yaogu and Qi Mu would actually be closer than Qiangzheng.

Everyone is connected to the Medicine Valley, who would have thought that between Qi Mu and the Medicine Valley, the mountain wall would be directly opened, and in fact, it would be possible to walk in half a day?

"Then, Grandpa Fei, ...... you" Mu Weiyang seemed to realize the key here, so he asked, "The hut you live in is actually Qi Mu's stronghold in Medicine Valley?" ”

Grandpa Fei nodded: "That's right, the Fei family has always been a retainer of the Gongsun family for generations, and since the day this passage was built a hundred years ago, every generation will have children living in the medicine valley hut and waiting, waiting for the people of the Gongsun family to appear." ”

Hearing this, Mu Weiyang's eyes suddenly became a little gloomy, and she remembered the distance between the hut that Grandpa Fei had been waiting for for generations and the entrance of this place, and her mood was depressed for a moment.

After a while, he seemed to have some regret and said: "If we had known this, we should have dealt with them in the hut and waited for your rescue, in this case, Di XVII might not have died." ”
