The Black Stone Well is the main passage to the underground pit, and in addition to these seven main passages, there are fourteen auxiliary passages.

The auxiliary passages are connected by hundreds of small passages, with a total of more than 500 large and small passages, and the pit is intricately like a vast underground labyrinth.

Even with the map, it took Gu Chen a full three days to reach the bottom of the pit.

At this time, the ancient dust plate sat on the ground, and after the fifty-dimensional tide cycle, the second main vein was as transparent and smooth as jade.

Gu Chen has just broken through the tide period of the three turns of Tongyuan, and the three turns of Tongyuan are the first small heavy days of the three small heavy heavens.

The road of refining the spirit is like a high-rise building, and the Yuan tide period is the foundation of the high-rise building, and only by laying a stable foundation can the high-rise building not fall.

Therefore, Gu Chen was not in a hurry to hit the second small heavy heaven pulse washing period, but the stable realm of patience.

Gu Chen took out the star mirror: "Oh, the Snowman King Spirit Seed has been sold?"

There are an extra 9,000 yuan stones in the star mirror, and you can extract the yuan stone by going to any branch of the one-star pavilion with the star mirror, or you can directly show the star mirror to trade with the yuan stone!

Suddenly, a cold light pierced the darkness.

The corners of Gu Chen's mouth turned up slightly, and with a flick of his fingers, the cold light swooped into the ground.

It turned out to be a swallow-tailed dagger.

Seeing that the assassination could not be achieved, the comer immediately rushed to the other side of the passage with his body in his body.

Rumble~

A piece of ore fell from the roof of the cave, blocking the man's path.

"You've been following me for almost a long time, Miss Rongrui!"

A masked girl shook the dust off her clothes: "You...... How do you know I'm Gu Rongrui?"

"This swallow-tailed dagger has your name engraved on it....."

Gu Rongrui's face hidden under the black veil was suddenly shocked: "Your eyesight ...... It's too strong!"

A spirit refiner who has broken through the barrier of life and death can perceive within a range of fifty meters, and the nine veins of Gu Chen have already been formed, and his five senses are ten times stronger than that of ordinary second-turn spirit disciples.

Not only can you perceive Gu Rongrui, but you can also clearly see every detail of her body.

"Miss Rong Rui should have been sent to the Gu Clan's Qian Zhuang with Gu Yong to train, right, why are you here?"

"I don't want to go to the bank!"

Gu Chen said: "Do you want to avenge your fiancé Gu Yong?"

Gu Rongrui said angrily: "Don't put the word Gu Yong in front of me!"

"Although he is from the Gu family, his parents died early, and it was my father who did his best to raise him, if it weren't for my father....... he would not have become a genius of the Gu family!"

Gu Chen thought that Gu Yong's talent could only be regarded as middle and lower, and it was impossible to awaken the four elephant spirits if he didn't take spiritual liquid every day.

"I, Gu Rongrui, are wholeheartedly devoted to him, but he hooks up with a woman like Gu Beiyan!"

Gu Rongrui saw the image in the star mirror, Gu Yong lived up to her sincerity, she ran away in a negative mood!

Gu Rongrui's shoulders trembled slightly, obviously very sad.

"Miss Rongrui, I advise you to go back first, Heishijing is not where you came!"

"Why can't I come if you can come?"

Gu Chen didn't say much, got up and continued to walk deeply, when suddenly Gu Rongrui's exclamation came from inside the passage.

Gu Chen walked forward quickly, Gu Rongrui's face turned pale and trembled, there were more than a dozen corpses in the passage, all of which were pressed under the boulder dozens of meters high, and the ground was covered with broken limbs and heads.

Bang~

Gu Chen used the power of the Eight Dings, and the boulder rolled down the passage into the ground with a clicking sound.

"You..... Your power..... Sure enough, it's as amazing as Brother Qianyi's brute force they said!"

After speaking, a large stream of blood gushed down from above, and Gu Rongrui vomited.

Gu Chen looked at the bloodstains, and his eyes flashed.

"I told you this is not the place for you!"

Gu Rongrui cleaned up her clothes and endured retching, and said, "I will never leave!"

There were mining trucks in the tunnels, but after the collapse, none of these tools were usable, and many of the tunnels were blocked, and it took at least four days to find the first pit deep underground.

Gu Chen stepped on the corpses all over the ground and continued to walk deep underground, and after a while, Gu Rongrui actually followed.

Half an hour later, the front suddenly opened up, and a huge circular crater appeared in front of Gu Chen.

The annular pit is covered with pitted zigzag marks, which are the traces left by the ironclad driller, the pit was not so big, but the part of the support above has been swallowed up by the ironclad driller, so this ring-shaped pit is formed.

"Help us!"

Two men lay in the middle of the pit, covered in blood.

"Gu Chengqiao, Gu Zhiyuan, why are you two here?"

"Miss Rui, we were bitten by the Ironclad Driller, there are hundreds of Ironclad Driller Beasts in the main mine below, it's terrifying!"

Gu Rongrui was about to step forward, but was blocked by Gu Chen.

Gu Chen held the jade slip in his hand: "Gu Chengqiao?"

"Are you..... We were trapped in the mine for three days, but the two deacons Gu Lin and Gu Qianhe were nowhere to be seen, but it was Deacon Gu Chen who arrived first!"

"There are more than 300 coolies and three spirit disciples below, we will take you to save them!"

Gu Chen nodded, hissing sound came from his right arm, and the cold air condensed in the Yuan Pool.

Burst~

Two heads rose into the sky, carrying large streams of blood.

"What are you doing?" Gu Rongrui was shocked by the scene in front of him: "They are the spirit disciples who are responsible for patrolling the Black Stone Shaft Mine!"

Gu Chen's fingers pierced Gu Lin's eyebrows, and a black insect the size of a grain of rice drilled out from the center of his eyebrows.

Gu Chen pinched the insect and said, "This is a brain eater!"

"The Yuanchi of these two people has been parasitized by brain eaters, and their brains have become a hive, and they are just a puppet!"

The two heads rolled around a few times and stopped at Gu Rongrui's feet, and the skulls were empty and just a skull.

Gu Rongrui leaned her head on Gu Chen's back, and her face hidden under the black veil was like white paper.

It wasn't until her extremely plump girl's delicate body repeatedly touched Gu Chen's body that she raised her head: "Why..... Why is this happening....."

"Are you going to follow me?"

Gu Rongrui's eyes were full of tears, and her makeup had already been spent: "I'm ...... I'm not afraid!"

"I want to prove to everyone in my Rongjun lineage that my Gu Rongrui is more than just a vase!"

"I can also contribute my own strength to the Gu family like other spirit disciples!"

"Even if it is...... Even if I don't marry Gu Yong, I still have the value of my own existence!"

Gu Chen's heart said, Gu Rongrui, like Gu Beiyan, was born in the Gu family's lineage and was pampered since childhood, but her heart is completely different from Gu Beiyan.

She seems to be weak, but she has her own persistence, which makes Gu Chen a little impressed.

Seeing that she insisted so much, she no longer persuaded her: "You can follow me, but be careful!"

Gu Chen walked up to the two corpses and took off the talisman iron armor on the corpses: "The teeth of the Iron Armor Drill Earth Beast are enough to bite the raw ore to pieces, and only by wearing the iron armor can you avoid being torn apart by it!"

Gu Rongrui pinched his nose and took a few steps back.

"If you don't wear it, you don't have to follow me!"

Gu Rongrui gritted his teeth, and then put on the bloodstained iron armor.

Gu Chen opened the map, and there were four places on the map that hit X, which should have been specially marked by Wu Mulin to remind Gu Chen.

However, Gu Chen had already walked through all three of them, and found nothing other than a few corpses.

What exactly does this X mean? It seems that only the position of the last X can find out

Rumble Rumble Rumble ~

Suddenly, Gu Chen pushed Gu Rongrui to the ground: "It's a beast tide!"
