Chapter 72: Seventy-second

"Click!"
A foggy sky-blue sword gas flashed across, and the ruler on the wall was square, and the large, heavy, dark-colored granite, with only a slight cracking sound, suddenly cracked and rolled down to a gravel.
Qiu Yutong closed his sword and stared. He saw that after the granite cracked, it was not a rock but a dark crack.
Sure enough! Qiu Yutong couldn't help but feel a little joy, and then took a deep breath, holding the squid oil candle in one hand, holding the edge of the gap in the other, and carefully probed half of his head into it.
He had just probed in, and he felt a peculiar coldness peculiar to the deep cave, rushing in from the darkness. The gap behind the granite, although only one foot wide, was very deep. At the end.
Qiu Yutong looked closely for a while and hesitated.
Obviously, this crack is a crack in the mountain. This kind of mountain crack is very common in rock mountains. It is generally very deep and long. I do n’t know where it will lead. Maybe it can lead to the outside. , No one can say clearly.
Qiu Yutong hesitated for a moment, but decided to give it a try. Even if it didn't work, it would be a big deal to come back. Anyway, the current situation could not be worse.
He thought about it and pulled the delicate landscape screen in the room to the wall, covering the gap a little, and kicked all the gravel on the ground under the bed, then hid a pillow under the quilt and pulled Go to the bedside tent so that from the outside, it looks as if someone is sleeping on the bed with a blindfold.
Qiu Yutong very seriously disguised the room. He looked at his achievements and couldn't help but be very satisfied. In this way, even if someone came in, he would not immediately find that he had escaped. How much can he fight for himself a little time.
After doing all the preparations, he carried the candle and squeezed carefully into the narrow gap.
This gap is only one foot wide, the stone walls on both sides are rough to the touch, and it is still a little wet. Qiu Yutong is holding the candle and squeezing slowly in it, and I can't help but feel a little joy. The candle has been burning very well There is ventilation in the gap, and since there is ventilation, it must lead to the outside world.
With confidence, he squeezed forward even harder. Gradually, the gap became wider, and two dark branches appeared in front.
Qiu Yutong couldn't help but stay, where should he go?
He only froze for a little while, and remembered that this had happened before. At that time, he and Lu Xiao encountered many forks in a maze canyon in the frontier of the Chen Dynasty. Lu Xiao used the small flag to judge the wind direction , And finally went out.
Although he does n’t have a small flag now, but a flame, it is more accurate than a small flag. Qiu Yutong settled down and moved the candle to the left side of the road. As a sword repairer, his hands were very stable and there was no tremor. The small clusters of flames burned quietly, without moving.
There is no wind on this road.
Qiu Yutong had a bottom in his heart, and then moved the candle to the right branch, and sure enough, the flame immediately quivered-this branch is ventilated.
He breathed a sigh of relief and walked to the fork on the right.
Along the way, the wetness became heavier and heavier, and water began to drip from the top of the head, and the feet became more and more slippery, and large patches of moss appeared
