The smell of these human oils caused all the vines to become agitated, making constant clicking sounds. From the perspective of Yue Guanchao and the others, it looked like tens of thousands of green snakes were biting and twisting in the cave.
In just one stick of incense, the cannibalism of these thorny vines has ended. All the vines have been bitten off their bodies and spread on the ground without any movement. The vines on the top of the cave have gradually become sparse from dense and vigorous, just like a person's head full of growth. Her hair was shaved into a short crew cut, and no matter how powerful the remaining rattan was, it couldn't do much!
"This is so amazing. Renyou actually wiped out the thorn vines without even using a single soldier."
When Xu Xiake saw that the cave was empty, his eyes widened in surprise.
Song Siyuan didn't expect that what human oil meant by covering up human scent. Although she didn't understand the principle, she could still see the subtlety of this kind of taking human power to change the world: "The effect of human oil is better than we imagined." Even bigger, once this problem is solved, it will be much easier to enter Cave Mountain."
Since the thorn vine no longer poses any threat, a plan has been put forward to enter Caoshan. Yue Guanchao and the other lamps were distributed to Xu Xiake, Ershu, Second Artillery, and Ren Kongque. Everyone picked up the torches and stood in the shape of "qi", wading The death thorn vines on the ground move forward.
After walking for nearly a hundred meters, they could already see the moist cold wind blowing from the front. Yue Guanchao and Xu Xiake stepped into the grotto first. When their steps stabilized and they looked in front of them, they had already arrived at the cave mountain deep in the cave!
"Come and see if this is the Cave Mountain described by Uncle Tang."
Yue Guanchao's shouts attracted everyone.
Song Siyuan and the others walked into the grotto and looked around. The low grotto was gone, and the empty valley suddenly opened up in front of them.
"I didn't expect that such a large river valley could be hidden deep in the cave!"
Yue Guanchao had to exclaim in surprise.
"This is the mystery of geological movement. The height of the mountain combined with the depth of the ground is enough to form such a wide valley."
Song Siyuan turned on the flashlight and observed the underground valley in front of them.
This river valley is similar to a trumpet, and its shape is close to that of a bellflower. They are standing on the cliff in front of the mouth of the trumpet. Looking down, they can see countless waterfalls flowing out of the cave and surging into the underground river.
The shape of this underground river is like an inverted T-shaped letter. The secondary river lies in front of everyone, and the main river extends forward along the lama's mouth. Until the sight disappears, the end is not yet visible.
If the main river channel is compared to the body of a trumpet, then the valley where the main and auxiliary river channels meet is the mouth of the trumpet that continues to extend outward. The surface of the left and right mountains is rugged, covered with various irregular caves, and there seems to be some ground vines and moss covering it. Above, the cold air blowing from other caves continued to ripple.
Looking up, the dome of the grotto is tall and open, like a starless night. Most of the eye caves on the surface are dark and blurry. Only a few large eye caves can let in the sunlight. Huge light beams are cast below the river, reflecting shadowy figures. Flowing light.
The most terrifying thing is not the physical underground mountain, but the erratic gray-black soul fog near Trumpet Mountain!
The mist is sometimes turbid and white, sometimes mixed with gray, like rich stove smoke, like paper money fly ash, like swarms of locusts, endlessly changing different forms, always floating near Cave Mountain, and the cold wind blows, and the smoke suddenly changes into other forms. , showing no signs of blowing away and disappearing!
These soul fogs are like tangible and insubstantial soul mountains. They cover the lama's mouth with thousands of meters of mist, making it difficult for people to see the reality clearly and the river course.
Ren Peacock looked at the soul mist and muttered: "How do these black smokes look like the insect swarms we saw?"
"Sister Ren, no, these soul mist are the insect swarms we saw."
Song Siyuan picked up the telescope and carefully observed the current situation of the soul mist. It was indeed gray-winged flying insects as she thought. Tens of thousands of insects swarmed, creating the thick black mist in front of her that never dissipated!
She put down the telescope and looked at everyone to confirm everyone's guess: "When we walked over just now, I saw the rattan near the cave. I guessed that the flying insects could fly to the tower after feeling the medicinal gas and stay in the cave. The flying insects are the gray fog we see!"
"No, these flying insects are also living creatures. How did they fly out? Don't the thorn vines eat them?"
Xu Xiake was puzzled. Once these flying insects appeared, they must be in swarms. Could it be that the thorn vine didn't react at all to such a big movement?
"Brother Xu, it's not that my Thorny Vine is indifferent to the flying insects, it's the flying insects that feed them!"
This statement made everyone surprised. Song Siyuan signaled them to calm down and explained to them the reason for such speculation: "Just now, when we were walking all the way, I found that there were undigested flying insects in the organs of the broken vine. I thought these These flying insects fed the broken vines and were able to break out with their strong group advantage."
"Think about it, if the thorn vines hadn't eaten a lot, the flying insects we saw on the tower would have multiplied ten times more."
