The miracle doctor came down from the mountain and opened a restaurant to raise his daughter

Chen Ning is not sure how deep he still needs to dig. Anyway, within the limit of what he can currently perceive, there are at most some slightly better jadeite stones.

Occasionally, he could sense that there were rough stones in the stone walls on his left and right sides, but Chen Ning didn't want to bother digging for them.

His goal is just one, keep digging until he digs out the Yuanjing vein.

As for whether it will take several days or even longer to dig, Chen Ning thinks it is impossible.

After all, the spiritual energy here seeps out.

If there is a depth of more than several thousand meters, the spiritual energy will not penetrate.

Another point is that Chen Ning's mining speed is much faster than a professional mining team.

If you dig for a few days, you may dig out tens of thousands of meters!

Chen Ning paused for a while and then continued to dig forward.

After advancing more than twenty meters again, Chen Ning paused to feel it, then turned slightly and continued to dig to the left, with a hint of joy on his face.

Zhen Luogui's eyes lit up when he saw Chen Ning's actions.

This must have been discovered, otherwise there would not have been a sudden change of direction.

Chen Ning did change the direction after making a discovery. He found a piece of rich spiritual energy seven or eight meters in front of him on the left. If there were no accidents, it must be a piece of Yuan Jing.

As long as the first piece appears, it proves that the real vein is not far away.

I don’t know how the original stone from the Zeng family ended up outside and was dug up. Maybe it was just an accident.

Chen Ning will not delve into those useless questions, he only wants what he sees and what he is about to get.

It took Chen Ning three minutes to reach a distance of seven or eight meters. He continued to output like this. Although it was not very draining for him, it was not as fast as the initial speed.

An irregular piece of black-red rough stone fell off from the stone wall.

Chen Ning swung his dagger again.

The original stone snapped, like tofu being cut in half.

"Yuanjing, there really is Yuanjing, Shura, we are developed!"

When Zhen Luogui saw a fist-sized milky white crystal exposed in the two halves of the original stone, he immediately yelled out of control.

However, Chen Ning was not as surprised as he expected. With a shake of his wrist, a few sword energy fell and the Yuan Jing was completely dug out.

"Pity!"

Chen Ning grabbed Yuan Jing and felt it for a moment, with a look of regret on his face.

"Huh? What's a pity?"

Zhen Luogui was completely confused. What's the regret after digging out the Yuan Jing?

"Feel it."

Chen Ning threw Yuan Jing to Zhen Luogui.

Zhen Luogui suddenly became nervous.

If there was something wrong with this Yuan Jing, he would really feel heartbroken.

Zhen Luogui held the Yuan Jing and directly used his own skills to absorb the energy of the Yuan Jing.

The reason why Yuanjing is sought after and valued by cultivators is naturally because the energy of Yuanjing is very close to the energy of True Yuan, and even the highest-grade Yuanjing can directly transform into True Yuan.

Even this intermediate Yuan Jing can be converted into 80% of the true Yuan energy as the technique runs for a few weeks.

Soon, Zhen Luogui felt a strong true energy entering the meridians in his body.

This made him excited.

Then there were some doubts. There was nothing wrong with Yuan Jing!

Just when doubts arose in Zhen Luogui's heart, his expression suddenly changed slightly, and it was obvious that he also noticed something was wrong.

After a week of Yuanjing energy running, Zhen Luogui felt a burning sensation in his meridians.

It’s fire element energy!

Although fire element energy is also energy, its limitations are much greater.

Unless it is a purely fire-attributed physique or skill, this energy will lower the value of this crystal.

"How could this be?"

Zhen Luogui immediately stopped and asked Chen Ning with confusion and regret.

"It's still unclear. Maybe there are volcanoes underground here, and the fire element has infected the crystal energy."

Chen Ning frowned.

He can only find such reasons to guess now.

Although the elemental crystal containing fire energy has no effect on him, after all, he has a five-element constitution, and any attribute energy can be directly transformed.

However, even if the fire element energy is extracted from this impure crystal, some quality will definitely be affected in the end.

"Volcano? It's really possible. It's really possible that the Yuan Jing was contaminated by thousands of fire elements and its quality was reduced."

Zhen Luogui agreed with Chen Ning's guess.

"It's just a guess. It's not necessarily the case. We'll find out if we keep digging." Chen Ning said.

"You don't want to die. If there really is a volcano and you dig through it, we will both die..."

"What's the name? You can hang up, but I won't."

Chen Ning directly interrupted Zhen Luogui's words, and then continued to dig forward with his dagger.

Before taking action, Chen Ning did not forget to collect the two halves of the original stone that wrapped the Yuan Jing. There were many glass-type jadeite inside, and they were also mutated red jadeite.

Not all Yuanjing is wrapped in jade, but more than half of the cases are like this.

If the mineral vein is truly reached, the elemental crystal will be directly exposed.

After hearing Chen Ning's words, Zhen Luogui's forehead turned slightly black, but in the end he followed obediently.

In the following distance, more and more raw jade stones appeared, but not all raw stones contained yuan crystals, and the proportion of yuan crystals appearing was less than one-fiftieth.

Half an hour passed in a flash, and it was already past six o'clock in the evening outside.

Chen Ning's digging distance to the depths has reached more than 300 meters.

When he arrived here, Chen Ning had already collected four pieces of Yuan Jing, each piece was wrapped in raw stone and was about the size of a fist.

At the same time, the deeper the time goes, the stronger the fire element energy in the crystal becomes.

Finally, Chen Ning stopped again, expanded the volume of his position, and sat down cross-legged to rest.

At this time, the temperature in this location has reached over fifty degrees.

Although Chen Ning's true energy is strong, he is still a little tired from digging non-stop for a long time.

This time, after resting for ten minutes, Chen Ning moved again, obviously slower than before.

It wasn't that Chen Ning was being lazy on purpose, but the density of the stone wall in front of him suddenly increased, and the stone wall appeared smooth and dark red.

The temperature here has reached around seventy degrees.

"Is there really lava behind this?" Zhen Luogui was a little nervous.

Even though he was in the middle stage of Qi training, if he was really wrapped in magma, he would instantly turn into fly ash.

He could easily escape outside, but here he was in a narrow hole hundreds of meters deep underground.

"Unlike magma, the density of this stone wall is too strong. I can only perceive a depth of two meters now."

Although Chen Ning said uncertain words, his tone was obviously a little excited.

"Have you discovered anything else?"

Zhen Luogui felt Chen Ning's emotions clearly.
