Standing up, he handed the water bladder in his hand to Chitu.

"Tutu, can you find the breath of water here?"

Meng Chen patted Chitu's head and said.

"Boom ......"

Chitu hissed twice in a low voice, not understanding what Meng Chen meant.

"Water, like this...... Is there any smell of water outside this Poisonous Fog Valley?"

Meng Chen even said with a gesture, poured out the water in the water bladder in front of Chitu's eyes, and accumulated a small puddle on the ground.

After a long while, Chitu seemed to finally understand what he meant, and pulled Meng Chen's sleeve with his mouth.

Meng Chen was overjoyed in his heart, turned over and jumped on horseback.

He came to the Shennong Grottoes for another important purpose, which was to find the essence of the water system.

At this moment, without any discovery, he suddenly thought of using Chitu's sense of smell to try.

Many horses have a strong ability to find water, and after the red rabbit mutated, all instincts have been greatly improved. This method is worth a try.

The red rabbit kicked out of the cave and ran forward.

That is, ten minutes later, a water source appeared in front of me.

However, this water source is just an ordinary small spring, and the water quality should have been polluted by poisonous fog for a long time, and there is nothing special about it.

At this moment, from a distance, there are several strange-looking poisonous beasts, drinking water next to the spring.

Urging the red rabbit, Meng Chen bypassed the spring from a distance, and continued to search forward among some strange plants and wild grasses.

However, those poisonous beasts also had very keen hearing, and soon they spotted Meng Chen, and each let out a roar and chased after them.

Meng Chen was no longer hiding, and galloped forward.

Along the way, he encountered more than a dozen scattered poisonous beasts, but he did not encounter a large group of poisonous beasts.

As he was running towards the front, Chitu suddenly let out two low screams, and then automatically turned around and ran southwest.

Meng Chen was slightly stunned, but he didn't stop it, he simply let go of the red rabbit's reins and let it run forward on its own.

It didn't take long for a man and a horse to come to the south near the mountain wall.

The red rabbit ran along the mountain wall for more than 100 meters, and then ran straight into a black vine.

"Boom......"

Not long after rushing into the vines, Meng Chen had already discovered that there was a crack in the mountain wall here, and he didn't know when it was formed.

The crack was not large, and could only accommodate one person to enter sideways.

Meng Chen took out a powerful lamp and shone it into the crack.

The fissures are deep and dark, and they don't know where they lead.

"Knock Knock Knock ......"

More than 20 scattered poisonous beasts also chased after them at this moment.

Without thinking about it anymore, Meng Chen took out his mobile phone, switched to Pan Feng's chat interface, and chose to descend to the Three Kingdoms World.

"Whew!"

A man and a horse appeared in the secret room.

Sending the red rabbit into the previous secret room, Meng Chen returned to the Poisonous Mist Valley, and the crack was in front of him.

Before the twenty or so poisonous beasts could react, he quickly dodged and entered the crack.

Turn on the powerful lamp, activate the power of the sun, and carefully grope forward.

After about 100 meters, the sides of the cave began to widen.

Meng Chen looked around, this should be another leyline.

The twenty or so poisonous beasts outside the crack were not small, roaring outside for a while, and seeing that they couldn't get into the crack, they slowly dispersed and went elsewhere.

Meng Chen no longer paid attention to the poisonous beasts outside, and continued to grope forward with a powerful lamp.

After a few tens of meters, after a corner, the leyline was much wider.

Take out your phone, return to the Three Kingdoms World, and bring the Red Rabbit back.

"Bunny, what did you find?"

Meng Chen patted Chitu's head and asked.

"Boom ......"

The red rabbit hissed twice in a low voice, and then walked towards the depths of the leyline.

After turning a few bends and forks, Chitu finally stopped in front of a blue-gray rock wall.

"Another crack......"

Meng Chen followed Chitu to stop, and soon found another crack the thickness of a finger on the rock wall.

Turning around, he used a powerful lamp to shine into the depths of the leyline, only to see that the front was still deep and long, and he didn't know where to lead.

Putting aside the exploration of this crack for a moment, Meng Chen turned over and jumped onto the red rabbit and searched deep into the leylines.

After turning a few more passages and entering a few forks, the entire leyline has come to an end.

No danger was found, and no treasures existed, only some poisonous mist that slightly penetrated from beyond the crack.

"Let's see what Chitu finds first. ”

Meng Chen turned his horse's head and returned to the crack.

Take out the Qinglong Knife and dig inward along the thin gap.

The stone wall here was very hard, and after more than half an hour, he dug into it more than half a person high, seven or eight meters deep, but still did not find the end of the crack.

But the gap was still there, and it had widened a little.

At this moment, the mobile phone in his pocket shook slightly.

Chen Yuan sent a message.

"Meng Chen, if this is the case, they have already found a way to activate the Heavenly Xuan Cannon...... There should be a rune mechanism on it, but it has been opened by Dorgon before, and it is not too complicated to activate now, so I will send you the method now. ”

Chen Yuan's voice came.

Just a moment later, a pamphlet appeared on the chat screen.

Meng Chen chose to receive.

The message inside is very simple, just two or three.

However, the characteristics of the spiritual interface, all the things that send materials and exercises, will basically be expressed in the form of booklets.

"Very good!" Meng Chen smiled at the corner of his mouth.

Find a way to use the Tianxuan Cannon, then he has one in his hand, a real "big killing weapon!"

A great killer that can threaten the god of war-level powerhouse.

"How's your situation there?"

Meng Chen typed and asked.

"I estimate that in a few hours, we will be able to reach the border with North Korea. Now the sisters are eating and resting, and when they are done, they are ready to cross the border with one go. ”

Chen Yuan replied quickly.

"Well, then I'll possess you right now and put away the Tianxuan Cannon first. ”

Meng Chen nodded.

"Okay, be careful over there. ”

Chen Yuan agreed.

Press and hold Chen Yuan's avatar and choose to descend to the world at the end of the Ming Dynasty.

Directly put the Tianxuan Cannon into the chat interface, Meng Chen did not pause, and immediately retreated.

Chen Yuan had no way to put this thing away by himself, and his mental power was far from enough.

......

Taking out the Yuan Energy Stone and recovering slightly for a while, Meng Chen re-lifted the Qinglong Knife and continued to dig forward.

About ten minutes later, a stream of Yuan Force breath came out from the gaps that had expanded a lot.

Meng Chen's spirits were greatly lifted, and while continuing to use the Qinglong Knife to excavate, he also summoned the wood-based sword embryo to assist in digging forward.

As a result, progress is much faster.

After more than half an hour, the Qinglong Knife that stabbed forward suddenly emptied, and finally dug out the end of the crack.
