"Sand Snake!" The tall and thin middle-aged man, led, narrowed his eyes and said in a deep voice.

"Must, you are here, hum, I've been waiting for you for a long time." The bald man spoke so sharply, like a snake's hissing sound.

"The Marshal has an order to capture the ore veins in the shortest time. How is the situation there now?" Must ignored the bald man's dissatisfaction and asked.

"The underground passage has been set up, and I can connect to the mine within two hours." The sand snake said sharply.

"Very good, take us over and have a look."

The sand snake waved his hand: "Come on."

Under the leadership of the sand snake, these people rushed towards the blue iron ore veins. In a valley more than fifty miles away from the blue iron ore veins, the sand snake stopped, pierced a huge rock beside the rock wall, revealing a deep hole.

"Wolf Fang, Sharu, you stay here with people." Must said.

Among the three, he is the strongest, a mid-stage warrior in Yuanfei realm, and the leader of his actions.

Two-thirds of the people were left behind, and the remaining masters of the Black Strike Empire followed the sand snake into the cave. There was a tunnel with a high man inside. Judging from the traces around, it was obvious that they had been excavated for a while.

After traveling through the cave for a long time, everyone arrived at an empty underground stone chamber, with four roads separated on the other side of the stone chamber.

In the darkness, the Sand Snake and his men's eyes were all shining, which was very strange.

Compared to on land, they seem to prefer to stay in the dark underground.

The sharp sound of the sand snake echoed underground: "I have dug four holes to enter the mines in various areas of the mine, so that they can't block them."

"Take me over and take a look." The tall and thin middle-aged man was not completely relieved.

The origin of this sand snake tribe was mysterious and was recruited by the Grand Marshal from somewhere. He joined them for a short time and was of great importance. Must was very cautious.

"Then come on." The sand snake licked its tongue and took Must and others to jump into a cave.

After walking in the winding underground cave for almost half an hour, Shashe led Must and others to the end of the cave. Shashe knocked on the mud and stones in front of him and said, "See, the stones here are mixed with blue iron, but the content is very low. They are abandoned ore veins that have been mined. Just dig another twenty meters and you can enter the abandoned ore cave in the west of the mine..."

Must stepped forward to check, reached out to grab a large piece of mud, mixed with some stones, emitting a faint blue light in the dark.

"It's indeed blue iron ore." Musiti nodded and asked, "How long will it take to dig these twenty meters."

"It's soon. One stick of incense will be enough." The sand snake said lightly.

"So fast?" Must was a little unbelievable. The soil here rarely had blue iron ore, which was very difficult to dig.

"Don't you believe it?" The sand snake sneered and went forward, and his black-lighted nails grabbed the soil. I don't know what method he used. His arms quickly stretched and stretched out, and pieces of mud and stone arched out from both sides, falling to the ground. In a moment, most of the sand snake's body penetrated into the soil.

...

In the darkness, Tang Xuan walked calmly in the mine veins and had been in the blue iron veins for several days.

Daily patrols. I have long been accustomed to Tang Xuan's powerful soul power. After a few days, the winding and twisting mineral channels have become very familiar. Since it is a patrol, Tang Xuan will not slacken. His soul power is fully opened, sweeping through any corner where people can be hidden.

Muran, a slight sound came from the darkness.

The sound was almost inaudible. For some reason, insects and snakes did not grow in the abandoned mine cave, so Tang Xuan was used to the silent world. This slight sound could not escape his keen six consciousnesses.

His eyes suddenly became sharp, his steps slid silently, and soon he reached the end of a dead end.

Hissing!

A slight sound is almost inaudible.

It is impossible for ordinary people to hear it. Tang Xuan sticks to the rock wall, and he feels that the sound is coming from the rock wall.

After calming down, he activated his spiritual thread to explore the rock wall. The range of mental power radiation would be affected by real matter. The hard ore vein rock wall weakened the range of Tang Xuan's mental power radiation in the past. If he could radiate a hundred meters in the air, twenty meters would be almost the limit now.

The sound only sounded for a while and then quietly became silent.

Tang Xuan's mental power just passed there, and a cold breath was noticed by him.

"Someone!"

Tang Xuan's expression changed slightly. He was extremely confident in his soul power and would not make any mistakes.

Although the aura was a bit weird, it should be a human. And he just swept over the mental power vaguely and noticed more auras. The humans who appeared in this situation must be people from the Black Empire. Unexpectedly, they had silently driven the tunnel so close to the mine vein.

Tang Xuan waited in place for a long time, and he wanted to confirm the number of the other party more.

But there was no movement across the rock wall for a long time. After a while, all the aura disappeared.

"Leave?"

Tang Xuan frowned, wondering why the other party had not opened the tunnel, wasn't he completely ready yet?

Tang Xuan guessed a lot of possibilities in an instant. The only thing he is sure is that since the tunnel has been opened so close to the ore vein, it is certain that the Black Front Empire is about to launch an attack. Not now, it is definitely nearly two days.

Generally speaking, once an attack is launched, it will definitely be very tragic. I just don’t know how many such tunnels will be.

Tang Xuan was sure that the Black Blade Empire would not only open one tunnel, and mine caves were scattered underground like spiders, which were simply a loophole that could be broken everywhere. With the ability to open one, the Black Blade Empire could completely open up more and tear up the defense in an instant.

"Other people must be notified as soon as possible."

Tang Xuan jumped out...

At the same time, Must and others were very satisfied after seeing the powerful burrow digging ability of the Sand Snake. As far as they know, the Blue Bear Tribe was suppressed by the Black Empire army in Blue Bear City, and almost all the masters defended the city. The defense of the mine veins would definitely be empty than before.

With the thousands of masters they brought, they were enough to capture the Blue Bear Mineral Vein in one fell swoop.

...

In the abandoned mine vein, where Tang Xuan heard the sound just now, the entire patrol team stood here. After Tang Xuan discovered the situation, everyone gathered together, including Tuyang and others from the Blue Bear Tribe.

At this time, Liu Xiang, as the strongest person in the team, was pressing his face against the rock wall, gathering his skills into his ears and exploring them carefully.

After a while, Liu Xiang shook his head and looked at Tang Xuan with great doubt: "Tang Xuan. You found them digging tunnels here. Why can't you hear any sound? You won't mistake the vibration underground for someone digging a hole."

The others also posted on the hole and listened for a long time, but didn't hear any sound.

"The person may have left for the time being." Tang Xuan said.

"It would be too much of a big deal to guess so many situations with just a little sound."

"What if it's true."

Some people in the team doubted it, and some people thought it should be taken seriously.

Tang Xuan could not expose his powerful soul power, so he could only insist that someone was digging the tunnel.

"Let me do this, I will report the situation to Lord Ya Ge. How to deal with it will be decided by Lord Ya Ge." Tuyang didn't know who to believe, so he decided to report it.

"Okay, but you'd better tell Lord Ya Ge. If the other party digs out a tunnel, there will definitely be no one, so be careful." Tang Xuan said with his best efforts.

"I will." Tuyang left quickly.

The others stood in the tunnel, and Tang Xuan said, "Everyone, I will stay here. I suspect that the people of the Black Empire will launch an attack soon, so you'd better stay as well."

"I'm crazy. I won't stay here. The shadowless thing will leave me in this dark tunnel." Mo Qian snorted coldly.

Tang Xuan ignored him and looked at the others.

"I'll stay here." Tan Zhuo said.

Zhao Jing and his wife hesitated for a moment: "We will stay, wait and see."

"Where are you, Fatty Wei." Liu Xiang looked at Wei Rong.

"I'll stay here and wait and see. I'm not afraid of ten thousand, but I'm afraid of anything." Fatty Wei hesitated for a long time and said.

"Since you believe in him, I will stay and see who is right." Liu Xiang said coldly.

Seeing that everyone else stayed, Mo Qian could only stay unwillingly, and hated Tang Xuan to death.

In the dark cave, although torches were lit, it was still extremely dull. Everyone was meditating to avoid severe oxygen consumption.

Before I knew it, the day passed and there was still no sound in the cave wall.

Mo Qian finally couldn't help but burst out, stood up and pointed at Tang Xuan and cursed: "Did you see? If someone digs a tunnel, wouldn't it be so long? It's all you little bastard, you have been in this ghost place for a day. Damn guy..."

Mo Qian stayed in the mine for a day and had already reached her limit. At this time, she burst out and cursed and vented the pressure.

"Shut up!" Tang Xuan raised his head suddenly, and his eyes emitted cold light in the darkness like sharp swords.

Tang Xuan's soul was powerful and he understood the prototype of the sword intent. Although Mo Qian's cultivation was two levels higher than Tang Xuan, in terms of will cultivation, it was 100,000 miles away from Tang Xuan. When Tang Xuan's eyes were stared at, it seemed to be put on by a sharp blade. He was stiff and his voice stopped abruptly.

Since joining the team, Tang Xuan has always regarded himself as a junior brother, being humble and low-key, and is even easy to bully in the eyes of some people.

This is the first time that everyone is angry when they see him.

Although most of the pressure was under Mo Qian, no one present was a master. The trace of sword intent that instantly leaked from Tang Xuan made them feel a bit harsh.

Tan Zhuo, Zhao Jing and others were secretly shocked. Thinking of the night that Tang Xuan said he had stabbed the Wolf King, he vaguely felt that this low-key junior brother was definitely not simple.

Liu Xiang felt that his face was offended.

Mo Qian had a close relationship with him. He suddenly stood up, his aura surged, and said coldly: "What are you doing? You can't stand it if you say a few words to your senior sister? And Mo Qian was right. It's been a day. If someone digs a tunnel, there will be no sound here. If you make a random guess, you will mobilize us to wait here all day. What's wrong with scolding you?"

Liu Xiang is a strong man at the eleventh level. When he reaches the point of binding energy into a stick, the true energy emitted is like a big stick of true energy, almost hitting Tang Xuan.

"You'd better take back your true energy."

Tang Xuan seemed to have no temper, but that did not touch his bottom line.

Song!

The long sword on his waist whispered softly and was automatically unsheathed half an inch. The invisible and sharp sword force shattered all the true qi sticks approaching Tang Xuan.
Chapter completed!
