The ancient and primitive method of making markings, Bing Sanfan obviously did it right.

The mark was indeed discovered by Yu Daqian, and he followed the mark along the way, and he was also a little closer to the meeting goal.

With the company of the divine beast Diting, coupled with seeing the mark of Bing Sanfan, Yu Daqian was more confident in finding Du Xiaomei as soon as possible.

In particular, Yu Daqian found that the hearing system of the divine beast is sensitive, and the visual system is developed, so it can hear distant sounds and see distant things.

This is somewhat similar to modern police dogs, but more sensitive and efficient than them.

These are the preliminary judgments made by Yu Daqian, which need to be further verified.

So, Yu Daqian exhausted the existing resources along the way to train the divine beast to listen:

Let it smell its own smelly socks, then hide them for it to find;

Let it lick the toffee, then hide it so that it can find it;

……

Just when Yu Daqian was constantly tossing the divine beast along the way, Bing Sanfan and Huo Sanjia had already arrived at the center of the main passage and sat on the ground to rest.

Bing Sanfan crossed Erlang's legs, his feet and thumbs moved around, and he hummed a song in his mouth. Huo Sanjia leaned against the stone and breathed comfortably evenly.

Just when he hummed two lyrics, Bing Sanfan heard a strange sound, and hurriedly turned over with Huo Sanjia, holding a self-defense weapon to beat the dog stick, and hid at the bend where the passage must pass.

After a while, the voice gradually approached, like a wolf and a dog, Bing Sanfan and Huo Sanjia raised the wooden stick in their hands high, and when they saw another shadow finally appear, the two of them immediately knocked the stick down.

"Click", in an instant, the two of them felt that the wooden stick fell to the ground and broke into two, but the black shadow just now dodged quickly.

"There is a situation! Get ready for battle! "It's Yu Daqian's voice!

As soon as Bing Sanfan heard the voice, he immediately shouted: "Is it Brother Yu?" I'm three sails~".

In this way, Yu Daqian and Bing Sanfan finally met in the cave, and the two were pleasantly surprised, hugged each other, and informed each other of their basic information.

Bing Sanfan couldn't help but be amazed when he learned that the white-headed and black-bodied monster with four ears just now was actually the divine beast Diting clan that Yu Daqian had captured and tamed.

"Good! It's worth the trip, it seems that there is such a ...... Four-eared, white-headed ...... Can't hear it? I hope it can help us. ”

Bing Sanfan was full of interest, looking at the truth in front of him and said.

Then, the real challenge began: Yu Daqian took out the items used by Du Xiaomei, let the Divine Beast Diting sniff carefully, and then signaled to start searching.

The divine beast seemed to understand, and began to get excited, and for a while he jumped over to see the little cub in Kan Yiting's arms, and for a while sniffed all over the ground and ran wildly.

And Yu Daqian, Bing Sanfan and others are now betting on the divine beast Di Ting, and they are willing to follow it wildly, tired and out of breath.

Finally, at the end of a passage, the Divine Beast stopped and began to smell, sniff, lick, and circle in earnest.

"Alas. Isn't this obviously a dead end, still tossing around like this, it seems to be a stupid dog, where is some kind of divine beast. ”

Seeing Di Ting, who was running around with high hopes, Yu Daqian first began to question a little.

"Hiss, hiss", the divine beast suddenly screamed! The voice was very excited, and he threw his claws at the wall of one of the caves.

Yu Daqian looked at it and suddenly woke up: Is there any way out here? Or is Du Xiaomei nearby?

Hurriedly everyone used the shovels and other tools they carried to dig a hole in the wall, and after a while, another mysterious passage was opened.

Everyone couldn't help but light up, and immediately followed Di Ting and walked over together.

"Oh my God!"

Everyone was surprised to find that at the end of the new passage, a stone house appeared.

The stone house seems to be very old, and the iron lock on the stone door has been rusted and mottled, and when you pull it, it will break with a bang.........
