"boom!"

When the golden dragon's tail hit the stone door.

"Buzz!"

The formation pattern on the stone door instantly emitted a dazzling golden light.

Then the body of the golden dragon turned into a golden light and flew back to the stone gate.

Its body transformed into a Tengtu again, but its appearance was different from before.

It still maintains that fat look.

"Boom!"

The stone door slowly opened.

A large amount of white mist seeped out from the gaps in the stone door.

Everyone felt comfortable bathing in the white mist.

"What a rich spiritual energy!"

Ling Feng's eyes narrowed slightly.

When the door opened to a width of half a meter, it stopped.

Ling Baichuan turned around and said to Ling Feng: "Brother, second brother, follow us in! Everyone else should wait outside, because only strong men in the Nascent Soul realm can enter this door!"

"Um!"

Ling Feng nodded, and then followed Ling Baichuan towards the open stone door.

The first elder and the second elder followed suit and walked in.

Ling Hai and the other six elders could only look at Ling Feng and Ling Baichuan helplessly.

Although they wanted to go in, Ling Baichuan didn't call them, and they didn't have the courage to go in.

Because Ling Baichuan said, it's not that he doesn't want to take them in, but that their cultivation level is too low.

Only strong men in the Nascent Soul realm can enter this door.

When Ling Feng and the others followed Ling Baichuan and entered behind the stone gate.

A long corridor appeared in front of me.

The air in this corridor is dry and fresh, without any musty smell.

"Bang bang bang..."

The oil lamp on the corridor wall also instantly lit up balls of flame, illuminating the entire corridor.

Ling Feng looked towards the end of the corridor. Even though his sight was very good, he could only see the area within a hundred meters.

Deeper, obscured by the white mist.

This corridor is very quiet and silent.

"Follow my footsteps and don't mess around!"

Ling Baichuan turned around and said to Ling Feng.

"Um!"

Ling Feng nodded.

Ling Baichuan's face was solemn, he turned around and walked forward.

His footwork is a bit mysterious.

When his feet stepped on the ground, a plum blossom immediately bloomed on the ground.

When he raised his feet, the plum blossom disappeared again.

Ling Feng stepped forward immediately.

The missing plum blossom appeared again.

The First Elder and the Second Elder followed closely behind Ling Feng.

Ling Baichuan led Ling Feng towards the depths of the corridor.

After the four people walked away and burned a stick of incense, an empty space appeared in front of everyone.

This was a spacious secret room. In this secret room, Ling Feng saw the puppets standing together neatly.

These puppets were covered in darkness and their eyes were tightly closed.

These puppets have different shapes, some are as high as ten meters, and some are only half a meter tall.

They have all kinds of weapons in their hands.

No, it should be said to be a tool.

Some hold hammers and chisels, some hold hoes, some hold files, some push carts, and some carry burdens.

"This is?"

Ling Feng took his eyes away from these puppets and looked at his grandfather.

"These are the machine puppets that specialize in mining!"

Ling Baichuan looked at the hundreds of puppets in front of him and said proudly:

"These are the treasures left to us by the ancestors of the Ling family. It's a pity that to drive these puppets, you need pure internal power. These internal powers, at the lowest level, require the true energy of the Nascent Soul realm!"

"Can't I use spirit stones?"

Ling Feng asked calmly.

"no!"

Ling Baichuan shook his head slightly:

"If it were possible to use spiritual stones, we would have used them long ago. Why wait until now?"

Ling Feng nodded, then walked to a puppet and observed it carefully for a while. The skin of these puppets looked like the skin of real people, lifelike.

Ling Feng asked: "How to control it?"

Ling Baichuan looked at these puppets and said: "As long as they are brought to the mining area and activated, the leader among them will independently observe the situation of the mineral veins and direct the work of these miner puppets!"

"So simple?"

Ling Feng's eyes lit up slightly.

He walked up to a puppet, then pressed his hands on the puppet's body, injecting the true energy in his body into the puppet.

After three breaths!

"Buzz!"

The puppet's eyes suddenly opened, and the formation patterns on his body lit up instantly, emitting a faint green light.

"Owner!"

The puppet immediately knelt on one knee in front of Ling Feng and let out a deep voice.

"You actually called me master?"

Ling Feng looked at the puppet in front of him with a smile on his lips.

"You used your true energy to activate it. It will naturally recognize you as its master and listen to your words!"

Ling Baichuan smiled faintly. He didn't expect Ling Feng to activate a puppet so quickly.

"So that's it, then let's take them all away!"

Ling Feng smiled and then released his domain.

"Buzz!"

His realm of heaven and earth enveloped these puppets.

Then, the pure true energy continuously floated out of Ling Feng's body, and was guided by his domain and instilled into the bodies of these puppets.

After a stick of incense!

"Buzz!"

"Buzz!"

"Buzz!"

After absorbing enough energy, each of the puppets was activated one after another.

"this?"

When Ling Baichuan saw this situation, his eyes widened.

He didn't expect that Ling Feng's domain actually had such a function.

After two sticks of incense, hundreds of puppets were all activated by Ling Feng.
