In front of the entrance of the No. 1 mine, the eldest grandson put on protective gear and prepared to enter.

The eldest grandson took a deep breath and sent a message to the communication device in his ear.

"Chenming, I'm ready to enter the No. 1 mine." Through the password translation, Bai Chenming received a message from his eldest grandson.

"Okay, eldest grandson, we will keep in touch with you in real time, if there is any danger, please call for support as soon as possible." Bai Chenming replied.

"Thank you, but after entering the smoke, our communication may be interrupted, please tell others, act according to the plan, do not enter the No. 1 mine, and will contact you as soon as you find it."

After speaking, the eldest grandson walked into the smoke.

The eldest grandson turned on the light on the top of the gas mask, and the lamp, which was powered by thunder stones, was corroded by the spiritual power mixed with the smoke and quickly extinguished.

"Damn."

The eldest grandson, who had lost his lighting tools, could only discredit the advance.

After walking more than ten meters, the mixed spiritual power around him became stronger and stronger, and the eldest grandson gradually felt the faint but irritable energy hidden in it, which was the evil thought.

The eldest grandson pressed to endure the excited evil spirit in his body.

At this time, it is like a vicious wolf that sees a lamb, ready to go wild at any time and devour all the evil thoughts around it.

The eldest grandson didn't want to startle the snake, and tried his best to control the evil spirits.

As the eldest grandson continued to go deeper, the concentration of evil thoughts around him became higher and higher, and due to the fact that the evil spirits were controlled, the eldest grandson felt a little difficult at this time.

Fortunately, although the evil spirit could not act wantonly, the evil thoughts that invaded the eldest grandson's body were easily devoured by the evil spirit, and the eldest grandson did not feel any danger in continuing to move forward.

On the other side, Lu Xiaoran and the others smoothly entered the central control room through the secret passage.

At this time, the control room was also shrouded in thick smoke, but Si Qin could sense that the concentration of evil thoughts in the smoke was much lower than that of the No. 1 mine.

"Chenming, can you receive it?" Siqin sent a message.

"Yes." Bai Chenming replied.

"We have entered the central control room, and now we are searching the safe house, the concentration of evil thoughts in the smoke here is much lower than that of Mine Road 1, I speculate that the danger is in Mine Road 1, remind the eldest grandson to pay attention to safety." Si Qin said.

"The eldest grandson has entered the No. 1 mine road, and due to the interference, he has now lost contact." Bai Chenming replied.

"This reckless man ......" Si Qin felt distraught for a while, and couldn't help but whisper.

"What's wrong?" Lu Xiaoran asked.

"The eldest grandson has entered the No. 1 mine and is now missing." Siqin briefly told everyone about the situation.

"Let's go according to the original plan." After a short silence, Lu Xiaoran said.

"I'm trying to fix the central control room, and find a way to connect our instant messaging devices with the contact runes in the control room, so that communication with the eldest grandson should be restored." Tang Xiaoyi said.

Lu Xiaoran nodded, "Well, the fat man and Tang Hao, you go with Xiaoyi, pay attention to safety." ”

Lu Xiaoran led the others in the direction of the safe house.

The eldest grandson encountered a problem at this time.

The eldest grandson stood at the fork of the No. 1 and No. 2 mines, and was a little hesitant whether to go to the No. 2 mine or continue to investigate the depths of the No. 1 mine road.

Due to the thick smoke, the eldest grandson could not release his spiritual power to investigate, so the eldest grandson did not know which mine path to take at this time.

Walking here, even the eldest grandson was a little tired, and silently estimated his state at this time in his heart, and the eldest grandson finally decided to risk being discovered by the possible remnants and release evil spirits to investigate.

The smoke of evil thoughts will make it difficult for mental power to move an inch, but for evil spirits, it is like a fish in water.

Just as the eldest grandson was about to release his control over the evil spirit, a voice suddenly came from the communication device in his ear.

"Eldest grandson, eldest grandson, can you receive it? I am filial piety. ”

"Yes."

"Whew, it's great that you're okay." The eldest grandson could even feel Xiaoyi's relieved emotion.

"I've just repaired the communication runes in the mine, and with the help of their runes, I've finally got in touch with you."

"How are you doing?" The eldest grandson asked.

"Lu Xiaoran, they are already rescuing the trapped people, and Tang Hao, Li Yuan, and I, together with them, are trying to repair the talisman array in the central control room."

"How's it going?"

"It's a little worse than I thought, the underlying structure of the rune array has been destroyed, and it will take some time to repair."

"Okay, stay safe. By the way, I'm at the fork in the No. 1 and No. 2 tunnels, can you tell if the problem is in the depths of No. 1 or No. 2? ”

"I'll take a look...... The energy fluctuating back from the depths of Tunnel 1 is strong, and it should be there. ”

"Roger." The eldest grandson continued to advance deeper into the No. 1 mine.

The aura in the mine became more and more violent, and the concentration of evil thoughts became higher and higher, and in the consciousness of the eldest grandson, he even felt that there were countless evil ghosts howling in his ears.

Just as the eldest grandson was about to go to the deepest depths, a dark shadow appeared in the eldest grandson's field of vision.

The eldest grandson stopped and looked fixedly at the fact that there was a man slumped on the edge of the mine in front of him.

The eldest grandson cautiously stepped forward to investigate.

The other party was wearing protective equipment, and he didn't know whether he was dead or alive.

The eldest grandson stepped forward and patted the other man on the shoulder, trying his best to make his voice pass through the mask and into the other's ears.

"Are you okay?"

The eldest grandson shouted a few times, and the other party finally reacted.

Through the mask, the eldest grandson could see that the other party had opened his eyes.

"Who are you? Why are you still here? Before the eldest grandson could ask, the other party actually asked first.

"I'm a rescuer sent by the Academy, who are you?"

The other party breathed a sigh of relief, as if he had let his guard down.

"I'm the mine manager, and my name is Fan Yuantao."

The eldest grandson recalled that the missing person was indeed the mine manager Fan Yuantao.

"Why are you here?" The eldest grandson asked.

"I'm here to find out why the tunnel collapsed."

"Did you find anything?"

"It's the bereaved! Ahem...... "Fan Yuantao is still a little weak.

"After the collapse of the mine, I organized the evacuation in the central control room, and found that a person sneakily ran towards the No. 1 mine. At first, I thought it was the miner who ran in the wrong direction, but as I chased after him, I noticed an anomaly, and he actually emitted a strong evil thought. There was a hint of fear in Fan Yuantao's words.

"How can you get here if you're not a martial artist?" The eldest grandson asked. In his memory, it is recorded in the employee information that the mine manager Fan Yuantao is not a martial artist.

"That...... Ah, the equipment I'm wearing is extra protection, and I would have died here without it. "Fan Yuantao is a little distracted.

The eldest grandson looked at it, and the equipment on Fan Yuantao's body was indeed a special level of protection.

"Do you know why he's here?" The eldest grandson asked.

"I don't know, I'm going to faint when I get here. Before he fainted, I saw him go inside. Fan Yuantao replied.

The eldest grandson thought about it for a while and decided to go and investigate.

"Stay here and don't move, the rescue team will come to your rescue." As he spoke, the eldest grandson got up and prepared to leave.

"I'll go with you." Fan Yuantao grabbed the eldest grandson.

Although Fan Yuantao is not a martial artist and is still a little weak at the moment, he has been in a high position for a long time and naturally speaks with an unquestionable momentum at this time.

The eldest grandson hesitated for a moment, and Fan Yuantao had already stood up from the ground and walked forward against the wall.

The eldest grandson caught up with Fan Yuantao and wanted to support him, but was refused.

"I can do it myself, you go ahead, I can follow you."

Hearing this, the eldest grandson did not insist.

He hadn't gone far before the eldest grandson began to notice something strange around him.

The surrounding aura was no longer as mixed as it was outside, and the air was filled with fiery fire aura and irritable evil thoughts.

The eldest grandson stopped.

In front of the eldest grandson is a huge cave that has been artificially dug out.

There is a cliff wall in the cave, about 10 meters below the ground, and below is hot lava, which illuminates the surrounding rock walls red.

The eldest grandson cautiously crawled to the edge of the cliff, and the traces of man-made mining could be clearly seen on the surrounding rock walls, and the small holes were left after the fire spirit stone was mined.

The eldest grandson poked his head out of the cliff and looked down.

The heat wave emitted by the hot magma could be felt by the eldest grandson through the protective mask.

This is the place where the No. 1 mine was first discovered, and even though it has been mined for many years, you can still feel the rich fire aura around you.

It's just that at this time, the surrounding fire aura is still mixed with evil thoughts, although the number of evil thoughts is not much, but it is extremely active, among the many fire aura, evil thoughts are like evil wolves, fierce and cunning.

Due to evil thoughts, mental power is still affected and difficult to detect stably.

The eldest grandson did not dare to release the evil spirit to investigate, for fear of being discovered by the bereaved family. Therefore, you can only rely on your eyes to find your target.

"No anomalies found." The eldest grandson looked at Fan Yuantao with some doubts.

Fan Yuantao was also cautiously searching downward.

After a while, Fan Yuantao also replied: "I didn't find it either, could it be under the magma?" ”

The eldest grandson thought for a moment and thought that there was also such a possibility.

The temperature of the magma is extremely high, but it is not a desperate place for a warrior.

As far as the eldest grandson knew, there were more than five kinds of body protection true qi armor in the sorcerer realm that could withstand the high temperature of magma, not to mention the powerhouses above the emperor realm.

"While he's still under the lava, I'll stay here, and you go back to move the rescuers." Fan Yuantao said.

"No, you're too dangerous here. I'll stay here while you go back. ”

"I'm exhausted when I get here, I don't have the strength to walk back. Okay, don't fight, time is pressing, and the most important thing is to pass the information back to the academy. Fan Yuantao shook his hand and said undeniably.

The eldest grandson wanted to insist, but seeing that Fan Yuantao had made up his mind, he had to give up.

Just as the eldest grandson was about to leave, a dazzling red light suddenly flashed below in the afterglow.

It's just a moment, but it's dazzling.

The eldest grandson bent down to investigate, and sure enough, he found the light source.

On the rock wall below, among the many potholes left behind after mining the fire spirit stone, one of the potholes was inlaid with a fire spirit stone the size of a skull.

Due to the dark red color of this fire spirit stone, it was like a stone without spiritual energy in the rock wall, so that the eldest grandson had not discovered it before.

After the fire spirit stone flashed with light, it dimmed again, but when you looked closely, you could find that there was a dazzling red color hidden in it, swimming like a spirit snake.

"You stay on it, I'll check it out." With that, the eldest grandson got up and jumped off the rock wall.

I saw the eldest grandson like a black shadow, sliding down the cliff wall strangely, the speed was extremely fast, but silent.

After the eldest grandson landed, he immediately fell to the ground.

After the surrounding airflow stabilized, the eldest grandson cautiously crawled towards the fire spirit stone.

Bypassing the hot magma, when the eldest grandson was still twenty or thirty meters away from the fire spirit stone, the eldest grandson finally saw clearly what the fire spirit stone was.

The eldest grandson was so shocked that he couldn't breathe.

"Tinder?!"

The dazzling red inside the fire spirit stone was actually a spark.

The eldest grandson didn't care that he might be discovered by the bereaved family, and mobilized the evil spirit in his body to probe towards the fire spirit stone.

"What a spark!" The eldest grandson was excited.

"No, there's something wrong with this fire spirit stone......"

Just when the eldest grandson was puzzled.

"What a strong evil thought......"

In the perception of the eldest grandson, a strong evil thought suddenly appeared in the rear.

It is precisely because the eldest grandson released the evil spirit to investigate, so at this time, the abnormality behind him can be discovered.

"What are you doing?" The eldest grandson exclaimed loudly.

At this time, Fan Yuantao on the cliff actually stood up, holding a bow in his left hand and pulling the string with his right hand, and a strange arrow was on the string.

The reason why it is weird is because the arrows are soaked in evil thoughts.

While the eldest grandson exclaimed, Fan Yuantao let go of the strings in his hand.

The arrow galloped in the air, and in the eyes of the eldest grandson, it was like an evil ghost dragging a tail to attack.

This arrow was not aimed at the eldest grandson, but at the fire spirit stone.
