At the beginning, I traveled through the wilderness, and I controlled the beasts to survive.

"I feel like I can give it a try."

Teacher Fang looked at the back of Han Ning's faintly glowing hand.

"So many amazing things have happened, I wouldn't be surprised if something special happens again."

Just as Han Ning was talking to the two teachers, his mental power suddenly moved.

Perspective changes.

Ahead, a dark red area appeared.

There was no flowing magma around, but just some ordinary dark rock walls.

But the Vientiane Spirit Silkworm in his body told him that the temperature here was only slightly lower than next to the magma lake.

How much it is, it cannot be converted into a specific value and told to him.

It doesn't matter if the Vientiane Silkworms don't know, all the traveling data is recorded in the detector, as long as the three rock-breaking ants return smoothly.

Suddenly, the motionless rock mass in front of him shook slightly.

A round head appeared in Han Ning's field of vision.

Immediately afterwards, a series of round heads broke through the rock wall.

They also discovered this rock-breaking ant staying underground at the same time.

There was barely any hesitation.

The owners of these heads let out waves of "silent" roars at the rock-breaking ants.

From those round heads of different lengths, clouds of dark gas were sprayed out.

Huhuhu~

The vision suddenly turned black.

Immediately afterwards, under the control of the Vientiane Spiritual Silkworm, the rock-breaking ants swished toward the rock wall above and quickly evacuated from the area.

"What the hell is this..."

Han Ning frowned slightly, recalling the appearance of those round heads.

Since the three rock-breaking ants did not move together, only one encountered those round heads.

The shape is a bit like a turtle head, but the eyes are very small, and the head is covered with bumps that look like rocks. Coupled with the darkness of the field of vision, he can't tell whether it is the head of a turtle or what it is. Soul beast.

I vaguely remember that there is no creature with a similar appearance in the Insek tribe's soul beast illustrated book.

"What's wrong?"

The two teachers noticed the expression on Han Ning's face.

"There is a situation over there at the Rock Breaker Ant, and they are attacked by unknown creatures."

…

It is one hundred and sixty kilometers away from the north gate of the college.

Under the gloomy sky with pattering raindrops, a huge figure with red skin cut through the dense fog and landed lightly on a relatively dry gravel ground.

Yinyi threw out the vines, tied up Han Ning, Dean Wu, and Leon and his daughter respectively, and gently placed them on the ground.

"Is this where the rock-breaking ant discovered the abnormality?" Dean Wu said, standing in the rain curtain holding an umbrella and looking at the gloomy scene around him.

"That's right."

As soon as Han Ning had an idea, three rock-breaking ants that had already joined together emerged from the mud with three small detectors firmly fixed on their backs.

He stepped forward and unhooked the three detectors respectively, handed them to Dean Wu, and said: "The ground here is rich in geothermal resources, but it has been occupied by a group of unknown soul beasts. We are here to explore them. Or should we continue to look for new geothermal resources?”

"160 kilometers... it's a bit far."

The one who spoke was Leon. He squatted down and twisted the wet soil on the ground.

"This is the geothermal location closest to the college in the north? Even if there are no soul beasts occupying it, with our current industrial level, it will be difficult to transmit electricity to an area more than a hundred kilometers away."

"Dad, look, what is that?"

At this time, Lisa, who was helping Leon hold an umbrella, suddenly pointed to a small pool of rainwater a few meters in front of them.

"What?"

Leon was slightly stunned. Under Lisa's guidance, the father and daughter walked to the pool. Leon leaned over, picked up a black stone from his feet, and put it in his hand to examine it carefully.

"coal?"

The moment they saw the dark brown stone, Han Ning and Dean Wu's expressions changed and they spoke in unison.

It's easy to verify whether the stone in Leon's hand is coal.

Han Ning motioned to Leon to throw the black stone to him, then held it in his hand and used his newly recovered mental power and spiritual energy in his body.

A faint red line lit up on the back of the hand, and red flames suddenly rose from the palm of the hand.

The flames enveloped the black stone, quickly evaporating the water on the surface and beginning to burn the core.

Gradually, Han Ning felt the temperature in the palm of his hand gradually increase, and a small cluster of light red flames that were very different from the psychic flames rose from the surface of the black stone.

Seeing this, Han Ning dispersed the released spiritual flames, only to see the small black stone in his hand wrapped in a faint red flame, burning quietly, with a slight red halo on the dark brown surface.

"When coal has more impurities and is not fully burned, the color of the flame tends to be red." Leon said while looking at the burning stone in Han Ning's hand.

As he spoke, he kicked the gravel on the ground again, and from a small shallow pit created by his toes, he pulled out a few small dark brown pebbles the size of fingernails.

Han Ning put the burning coal mine on the ground, shook his hot palms, and murmured to himself:

"Could it be said that there is a coal mine here?"

He looked at the area where the coal was found, and directed the three rock-breaking ants to dig up the surface soil and dig down as far as possible.

Three rock-breaking ants with a body length of about 2 meters suddenly turned into digging machines. Their purple-red forelimbs were pointed at the ground and they kept digging.

Their forelimbs are powerful and extremely thick, and are attached with earth elements, making them very powerful in penetrating the soil layer.

After a while, a large pit with a radius of 3 meters and a depth of almost 2 meters appeared in front of the four people.

At the bottom of the pit, a scene of black and brown appeared.

In order to verify whether the black stones below were coal, Han Ning used his mental power to send a message to the egg cake:

"Don't use red lotus fire, just use ordinary flames and spray flames towards the bottom of the pit."

The red lotus fire of the egg cake is difficult to extinguish, and it will automatically absorb the surrounding fire spirits. This kind of flame is not convenient for testing.

"grumble!"

Egg Pancake, who was lying behind Han Ning, put his huge head over and opened his mouth slightly.

Phew~

Ordinary orange flames spurted out from its big mouth, covering the pit in a sea of ​​fire.

Huhuhu~

The temperature in the pit increased extremely, and flames that were not jets of egg cakes rose up. When they encountered the oxygen from the outside, red spots began to appear on the surface of the black stones, and they began to burn violently.

Dean Wu stared at the black coal burning quietly at the bottom of the pit, with a hint of joy on his face:

"Yes, it's coal. I didn't expect that there is a coal mine here. I just don't know how big the reserves are."

Lyon said:

"It is very simple to determine the approximate reserves. As long as Han Ning directs three rock-breaking ants to use this as the center of the circle, dive into the ground, collect rock specimens of a certain weight from nearby at intervals, and repeat this many times to roughly calculate it. The storage capacity of coal mines.”
