The next morning, it was still pitch dark.

Leng Qing pulled Tang Yue out of Zhao Xin's room.

Looking at Zhao Xin, who was sleeping soundly on the sofa in the living room, he went to the bathroom lightly to start the day's cleaning.

After a while, the sound of water hitting the ground woke up Zhao Xin in the living room.

Zhao Xin got up and looked at the time on the mobile phone next to him, and found that it was very close to the agreed departure time yesterday.

Because it is to investigate the clues of the Black Holy See, in order to keep the operation secret, it is necessary to leave Bo City before dark.

After getting dressed, he knocked on the door of Qin Yu'er's room.

After a few seconds, Qin Yu'er came out with a little dark circle under her eyes.

It seems that this time the demon hunter Qin Yu'er is still very worried about Zhao Xin, and he hasn't slept well for a long time.

Zhao Xin said distressedly. "Why are you still so worried about me, I'm already a mid-level mage. You can't be by my side all the time in the future, have faith in me in this dangerous world, believe me!? ”

Qin Yu'er looked at Zhao Xin's expression, and her heart was still a little sweet.

"Got it, got it, hurry up and wash up and get ready to go."

"Well, Sister Yu'er, you can rest more on the road." Zhao Xin let the way and said with concern.

……

The dawn of dawn had just fallen, and Zhao Xin and his party of four had already left the Snow Mountain Peak Station.

Walking in the dawn forest, Zhao Xin immediately felt a cold and damp breath.

In the distance, from time to time, there was the howl of an unknown beast, which was terrifying!

Look at the surrounding green woods and the bumpy road underfoot.

Zhao Xin opened his mouth to break the silence.

"Almost, I shouldn't be able to see this place at the post station, now look at me."

Then the star track is skillfully connected.

"Dimensional Summoning!!"

Xiao Dark's head poked out first, and saw Zhao Xinhou's body dozens of meters long quickly fly out of the silver dimensional gate.

Leng Qing was surprised when he saw Zhao Xin's summoned beast for the first time. "It's amazing, you can have a wurm at such a young age, and your future is limitless."

Zhao Xin said embarrassedly. "It's all the help of Sister Yu'er and Tang Yue, otherwise I wouldn't have been able to contract with Xiaodark."

He patted the small, dark, smooth, thick scales.

"Come up together, with the speed of the small dark flight, it will be a few hours on the road in a few days."

With such a good mount, Qin Yu'er and the others were no longer hypocritical, and jumped up one after another.

Xiao Dian didn't have the dignity of a dragon, so he didn't lose his temper and directly agreed with Qin Yu'er and them to sit on the body.

Zhao Xin finally jumped on Xiao Dark's dragon body and hugged her from behind Qin Yu'er.

"You didn't sleep well yesterday, let me hold you and sleep at ease, Xiao Dian still flies quite steadily."

Qin Yu'er felt the little dark flight mode, and fell asleep in Zhao Xin's bad with peace of mind.

Xiao Di flew at a low altitude of dozens of meters, and the green scenery below was constantly changing.

……

A few hours later, the sun had fully risen.

Xiao Dian sent Zhao Xin and his party to the platform next to the cave in Baicao Valley.

"How~" and went back to summon the plane to rest.

Zhao Xin led everyone to the pond.

"That's it."

Leng Qing walked over after listening, took out the test paper and put it on the surface of the pool water to float a layer of splash.

The test strip changed from white to red, and the cold blue was solemn. "It seems that this pool of water is not a small problem, if it weren't for the fact that this berserk effect was diluted by water, the Xuefeng Mountain Station would have been attacked by demons a long time ago."

Zhao Xin looked at the smart Leng Qing and guided. "Maybe it started a long time ago, the giant-eyed fishy rats under Bocheng have dug holes for so long, and the demons can be artificially guided to directly attack the Bocheng area."

Tang Yue seemed to think of something, and her face changed drastically.

"This kind of large-scale plan can only be completed by the Black Holy See! We're going to have to find a way to stop it. ”

Leng Qing still said calmly. "Let's go to the cave and see the water source."

With a glow in his hand, he walked ahead and entered the cave.

Zhao Xin and the others glanced at each other and followed in, and Qin Yu'er volunteered to press the formation at the end.

I walked along the stream that flowed into the pool at the entrance of the cave for about ten minutes.

The cave suddenly became brighter, and under the cold blue light, the cave was full of jagged and strange rocks, and there were stalactites hanging down all over it.

It seems that it was formed by the erosion of the underground river for many years.

"The underground rivers are generally connected, and it is not too far from Bo City, and what Zhao Xin said is also a bit reasonable." After Leng Qing observed for four weeks, he affirmed Zhao Xin's conjecture before.

After walking along the creek for a while, there was a collapsed pile of rubble.

Zhao Xin climbed over to the collapsed boulder alone, and touched the traces on the stone with his hand.

"These collapsed boulders were all recently blown up, and there is still saltpeter black ash left over from the explosion of gunpowder."

Leng Qing walked towards Zhao Xin while preparing for magic, and the seven constellations were built into a star palace, and the huge star palace was reflected in the cave.

Zhao Xin, who had just lost his sight because Leng Qing wanted to magnify his move to revoke the glory, saw the surroundings clearly.

After more than ten seconds of casting.

"Dragon Vein of Rock: Earth Sinking"

The loud sound of "boom~~~" is endless.

Leng Qing quickly softened the surrounding collapsed rocks, and was kneaded and shaped by Leng Qing and flowed to both sides.

After about a few minutes, Leng Qing finally opened the collapsed passage.

"Let's go!" I saw Leng Qing, who was overconsumed, panting and taking the lead.

It seems that there is still a lot of pressure on Leng Qing to continue to use super-level magic.

Tang Yue couldn't look at it and ran forward to support Leng Qing.

"You might as well rest in the middle of the group for a while. I'll take the lead, just in case. ”

Seeing this, Zhao Xin also stepped forward to support Leng Qing so that Tang Yue could let go of his hands and feet.

Leng Qing knew that he was not in a good state, and he did not refuse Tang Yue's kindness, and let Zhao Xin take him through the middle of the team.

When everyone walked out of the chain of collapsed passages, they came to a larger cave.

However, the soles of this place are full of collapsed stalactites, and it is estimated that it was a low-lying area in the past, and it was artificially destroyed to its current appearance.

Without the guidance of the stream, Qin Yu'er circled around the empty cave. Leng Qing, who returned to the cave mouth to rest with nothing, shook his head.

Zhao Xin looked at Qin Yu'er, who hadn't found anything, and used his water magic energy to try to perceive the water around him.

After a while.

"There it is!!"

"What's up?" Tang Yue looked at Zhao Xin, who suddenly shouted, and was puzzled.

"I sensed a large amount of water more than a dozen meters below our feet, which should have been formed slowly by the creek blocked by the collapse of the channel."

Zhao Xin also lay on the ground and listened to the movement below.

Tang Yue observed for a while and found that there were some gaps in these piles of rocks.

"You wait for me for a while, and I'll go and go back."

The shadow star tracks quickly connected, turning into a cloud of shadows and burrowing into the cracks in the dark underground stones......
