The rumbling sound was approaching, and the vibration of the entire mine became more and more intense. There were even a lot of rockfalls that fell from the roof of the cave.

"Let's go! Something is coming! ”

Lin Yu took out the Poké Ball and put away the caller at his feet, pulled out his legs and ran out of the cave.

But the thing came so fast that in a few moments a huge rock head poked out from behind them.

"It's ...... Big Rock Serpent! ”

[Great Rock Snake, Rock Snake Pokémon.] When digging earth and rocks underground, it causes the ground to shake. Underground, the speed of movement is eighty kilometers per hour. ]

"Roar!"

With the vigorous advance of the Great Rock Snake, the already fragile mine cave was immediately unable to withstand it. Large chunks of earth and rocks fell from the roof of the cave.

"Oops! It's going to collapse here! ”

"Leo Road! Vacuum wave! ”

"Leo!"

The vacuum wave hit the big rock snake that bit towards Lin Yu and the others head-on, and the big rock snake was in pain, and its body was crooked, and the impact of the rock body caused the mine to collapse in a larger area.

"Oh no, Brother Yu, there's no way ahead!"

Ma Jie's voice came from the front. Lin Yu looked at the big rock snake that had woken up behind him, and said busily: "Everyone! Come on! Climb on top of the Big Rock Serpent! ”

"Broken Rock!"

"Bang!" With a bang, Leo Lu punched hard, embedding the head of the big rock snake that had opened its mouth to bite again into the cave wall. Lin Yu and the others seized the opportunity and climbed onto the body of the big rock snake one after another.

The big rock snake struggled twice, but it couldn't bite Lin Yu and the others on its back, so it twisted its head and went directly into the rock wall, trying to bury Lin Yu and the others alive in the mountain with a hole.

"Roar!!

The roar of the big rock snake and the constantly shaving earth and rocks made Lin Yu's ears buzz, and he could only hug the body of the big rock snake tightly with Leolu, trying not to be thrown out......

"The owner of the Little Feather Pavilion...... Do you want to use the power of the Great Rock Serpent to dig a way out......"

"But...... This big rock snake keeps ...... down."

The doctor's voice came from behind him. Indeed, the Great Rock Serpent is digging down, and if it continues like this, they will most likely be buried alive here......

"We must find a way to control the direction of the big rock snake......"

Just when the six gods were without a master, Lin Yu only felt a flash of light behind him, and the doctor actually called out the green caterpillar.

"Green caterpillar, spin silk!"

"Oh!"

Silver worm silk spat out and circled around the neck of the Great Rock Serpent, forming a ring of reins. The doctor took his hand, and the big rock snake roared sadly.

"Xiao Yu Pavilion Master, Xiao Jie, Leo Road, hurry! Let's pull! ”

Several people immediately understood the doctor's intentions, and immediately grabbed the reins formed by the silk. The big rock snake roared, and was pulled by the reins to change direction.

"Green caterpillar, hold on!"

"Oh!"

The silk threads kept breaking, and the green caterpillars kept spitting out new silk threads. In this way, several people rode the big rock snake and galloped through the mountain.

Finally, with a "bang", the big rock snake escaped from the mountain, and several people saw the light again.

"Let's go! One, two, three, jump! ”

"Leo!"

Several people seized the opportunity and jumped back on the mountain road.

"Roar!"

The serpent roared, turned around and drilled into the mine again, leaving two large round holes in the surface of the mountain.

"Hoo ......"

Lin Yu wiped his sweat. This time it was a narrow escape. "Wild adventures or something, it's a little too exciting......"

"I actually took a roller coaster ride in the mine or something......"

"yes. This time thanks to the Doctor and the Green Caterpillar. ”

Ma Jie said.

"The old man is just, like the owner of the Xiao Yu Pavilion, trying to believe in his elf companions, and trying to find a breakthrough with the elves......"

"Hehe, fortunately it worked. The old man can also understand a little, what the owner of the Xiao Yu Pavilion said, "As long as you believe in the bond with the elves, any difficulties can be overcome". ”

The doctor touched the green caterpillar's head, and the green caterpillar happily responded.

"It's a pity that I'm not mature as a trainer, and I can't be a good partner with the big charcoal car......"

"Didn't help anything......" Ma Jie looked enviously at the doctor and the green caterpillar.

"What are you talking about...... Lin Yu patted Ma Jie's shoulder affectionately.

"The old man is sad and sad here, isn't it disgusting to you."

"Haha...... Hahahaha! ”

Suddenly, the aftermath of the catastrophe made all three of them sit on the mud floor and laugh happily.

[Dust of White Light: What's the situation?] Then I saw a big head of stone, and then it was black in front of me......]

[Slag Luo LO: Did the anchor go around underground? There's no light at all, nothing can be seen! 】

[Wang Qihang sail: I only heard the sound of booming and booming]

"It seems that everyone still doesn't know what's going on......" Lin Yu looked at the barrage in the live broadcast room and said with a smile.

He patted the dust off his body and walked with Leolu to the hole that the Great Rock Serpent had dug.

"Wow...... What a deep hole ......"

"Everyone, we just rode an elf and got out of a hole under the mountain!"

"Now that I think about it, it's a thrilling experience......"

"Yes! It's a life experience that only a trainer can have! Ma Jie also came behind Lin Yu.

"I'm getting more and more interested in being a trainer! Entrusting each other with elves and embarking on a journey together is really ~~~ great! ”

"Brother Ma, you're already a trainer, okay. It's just that you have to work hard to learn the basics. ”

Lin Yu scolded with a smile.

"When I talk to the doctor about those attributes, various skills, and so on, you're always dozing off......"

"Isn't that stuff too boring? Ah I see, I'm going to study hard to become a strong trainer! ”

"Actually, can you cause such a lot of damage?" Ma Jie looked at the deep cave and sighed.

"The elf called the Great Rock Serpent...... The destructive power is terrible......"

"Not necessarily...... You see......"

The Doctor also walked over and pointed to a cave where the great rock snake had come out.

There, a gopher curiously poked its head out of the soil, and after seeing the burrow dug by the big rock snake, the gopher dived again with a surprised look. Then, many gophers appeared in the burrow, chattering happily.

"These gophers seem to have taken the cave formed by the passage of the big rock snake as their own residence."

The doctor sighed.

"Does the symbiotic relationship in nature also exist in the elven world...... It is precisely because of the large rock snakes digging holes in the mountains that the gophers have their own homes......"

"Elves, they're really forming their own ecosystem......"

"The Doctor is sighing at the magic of the elves again."

Seeing that the doctor looked interested in the cave, Ma Jie pouted a little boredly.

Then, by accident, he saw the green caterpillar on the doctor's shoulder......

"Ahh Doctor! ”

"Green caterpillars! Look! Green caterpillar him! ”

Lin Yu and the doctor were both stunned, Lin Yu turned his head, and saw that the green caterpillar was emitting light......

"It's ......"

"Green Caterpillar...... Going to evolve? ”
