The spiritual power flowing out of the black stone frantically poured into Yu Shu's body, without the slightest hindrance or condensation, as if it was his own power.

Of course, this is because the spiritual power is very pure, and it has no attributes, just like a simple heaven and earth aura.

Yu Shu's eyes gradually showed a look of surprise, and a trace of joy that could not be concealed.

With the influx of spiritual power, a warm current flowed through Yu Shu's body, and Yu Shu finally felt the feeling of having power again.

It's just that a moment later, I only heard a soft "pop".

The black stone in Yu Shu's hand shattered and turned into white stone chips, and the spiritual power in Yu Shu's body had actually returned to about one-third of its heyday.

Yu Shu felt the power in his body, and suddenly his wrist flipped, and the Nether Seal suddenly appeared, "Yu!"

"Buzz!"

With a hum, a golden curtain of light appeared around Yu Shu's body.

Yu Shu closed his eyes slightly, as if he was feeling the flow of spiritual power in his body.

After a long while, he opened his eyes again, and then the Nether Seal and the golden light curtain disappeared in an instant.

After testing, it was proved that the spiritual power contained in this black stone could indeed be absorbed and used, but it was ...... His own problems remain unsolved.

In other words, he can only use as much spiritual power as he absorbs, and he can't recover it on his own. When the absorbed spiritual power is used up, he will become in a state of spiritual power loss again.

It's a bit of a pity.

It's just a palliative, not a cure.

Yu Shu sighed slightly, and then a smile appeared on his face.

But in any case, at least it is better than before, as long as there are enough of these black stones, even if there is any danger, there is no need to be afraid.

And...... It was unheard of for this black stone to contain such a huge amount of pure spiritual power.

It's not that Yu Shu hasn't thought of a similar method before, but the kind of heavenly and earthly treasures that are born with pure spiritual power are really too rare and precious, and other people's spiritual power has their own attributes, and Yu Shu can't use it when he can't use the soul chapter.

I didn't expect this kind of thing similar to the "spirit stone" in the novel to be seen in Lijiang.

Yu Shu breathed a sigh of relief and looked at Ma Hanshuang, "Director Ma, this thing...... Where did it come from?"

"Near Lashi Lake. ”

Ma Hanshuang opened his mouth and said softly: "To be exact, it is the Ancient Demon Cave hidden around Lashi Lake, which is the source of that gray fog!"

Yu Shu's eyes froze slightly, and then asked, "That demon cave actually has this kind of stone that contains a huge amount of pure spiritual power?"

"Yes. ”

Ma Hanshuang nodded, "According to our analysis, it should be a naturally formed spirit stone after the demon cave was banned in ancient times, and the spiritual power could not be leaked. ”

"Is it a lot?"

Yu Shu asked again.

"Not much. ”

Ma Hanshuang shook his head, "A fist-sized one like this, only a dozen pieces have been excavated, but ...... Based on our investigations, we suspect that there may be a large number of these spirit stones in the depths of the Demon Cave. ”

"So ......"

Ma Hanshuang looked at Yu Shu and said, "If Mr. Yu is willing to stay for a while to help, the spirit stones excavated in the demon cave, except for a small part for research, can all belong to Mr. Yu." Moreover, this kind of spiritual sense is very strange, and if it is studied thoroughly, it may have an effect on the problem of Mr. Yu's spiritual power being lost. ”

Hearing Ma Hanshuang's words, Yu Shu groaned slightly, but he didn't hesitate for long before nodding in agreement.

Although I came out to travel this time, since I have the opportunity to solve the problem of my spiritual power loss, even if it is only a symptom but not a cure, it is worth giving it a try.

As for Xu Xiyan, Xu Zhishui and Wang Xiaoling, they can only be wronged to wait for a few days.

Seeing Yu Shu's promise, Ma Hanshuang's face couldn't help but show joy, and he immediately got up and took out a suitcase from the drawer and put it in front of Yu Shu.

Inside the box, there were thirteen black stones the size of a fist, which looked unremarkable, as if they had been picked up by the side of the road.

"This is all the spirit stones we've found so far, I hope they can be useful to you. ”

Ma Hanshuang said.

"Thank you. ”

Yu Shu took the box, and then asked, "So what do I need to do these days?"

"Probe!"

Ma Hanshuang didn't hesitate before speaking directly: "Although we have already determined that the source of the demon fog is the demon cave near Lashi Lake, but just like the demon fog that suddenly appeared in the ancient city yesterday, because of the underground cracks, we can't predict that the demon fog will appear there next time." And Mr. Yu, you have a strong spiritual sense, so ...... I hope you can find out all the suspicious locations around the old town of Lijiang, and then I will send someone to seal up those underground cracks to prevent the situation in the ancient city from happening again yesterday. ”

"Exploring all the perimeter of the ancient city?"

Yu Shu couldn't help but be stunned for a moment, and then nodded with a wry smile, "Okay, I know." ”

"Thank you. ”

Ma Hanshuang stretched out his hand towards Yu Shu and said with a smile: "I will send a few guys who are not weak in spiritual sense to assist you." ”

"Good. ”

Yu Shu stretched out his hand and shook Ma Hanshuang, and before the words fell, he heard the office door being pushed open.

Turning his head to look, he saw Zhang Leshan scratching his head and walking in, shouting: "Boss, now the public opinion on the Internet is about to explode, saying that there are demons here in the ancient city, let's ...... Huh, the Nether Brother is there, too?"

Yu Shu smiled and nodded at Zhang Leshan, which was regarded as a hello.

"Get in here. ”

Ma Hanshuang glared at Zhang Leshan and said, "What do you look like when you are shocked, you are also a deputy director, so you can't be calm?"

"You're so calm, if I keep a straight face again, how dull the atmosphere in our department is. ”

Zhang Leshan seemed to be used to being scolded, sat on the sofa with a hippie smile, looked at Yu Shu, and said, "Brother Nether, I haven't thanked you for helping last night." ”

Yu Shu grinned, "Then how are you going to thank me?"

“……”

Zhang Leshan was stunned and speechless for a long time.

Big brother, I'm just going to be polite first.

You suddenly asked me how to thank you, I ...... How can I thank you?

Is the remnant of the legend's great, bright, and correct hero, so choking?

Zhang Leshan couldn't help but roll his eyes, and silently refreshed the image of Yu Shu in his heart.

"You're just in time. ”

Ma Hanshuang glanced at Zhang Leshan, and immediately said, "Today, in a few days, you can cooperate with Mr. Yu." ”

"Huh?"

Zhang Leshan was slightly stunned, turned his head to look at Ma Hanshuang, a little unclear.

"I invited Mr. Yu to stay and help. ”

Ma Hanshuang said lightly: "So from today onwards, you and your perception team will be under the command arranged by Mr. Yu." ”
