Chihu Island in the middle of the lake.

Zhang Shenling was also frowning and looking at the turbulent picture scroll in front of him.

"The Jinlan Sect has just sent news that a big fish in the Sea of Darkness has destroyed the Holy Blue Peak." Zhang Yuxian appeared on the top floor with a solemn expression.

"Big fish? How could it be that it was pulled into the sea of no light? ”

Originally, a million mountains were enough to give people a headache, but now there is another sea of light.

With a sigh of relief, Zhang Shenling calmed down, "I know, let's add a group of early and mid-stage Qi cultivation monks to Nanze Pass." ”

In addition to mobilizing the monks to go south, there was also an order that was quietly sent from the island in the middle of the lake to the dozens of mundane cities controlled by the Zhang family.

Zhang Yunyuan looked at the jade slip in his hand and fell into deep hesitation, and soon after, he called Zuo Qiu Zhuo.

"If you want to test the spirit root talent for all the people in Linyuan City, how many spirit stones do you need?"

Zuo Qiu Zhuo looked surprised, "My subordinates don't know, but a hundred thousand spirit stones may not be enough." ”

"One hundred thousand ......" Zhang Yunyuan took a deep breath, "The family will send over 30,000 spirit stones next month, you first think about a way, can you use 30,000 spirit stones to find out all the mortals with spirit roots to the greatest extent." ”

After sending Zuoqiu Zhuo away, Zhang Yunyuan also locked himself in his refining room.

Scorching flames burned all around, and he felt as if he didn't feel anything.

The success of the Wind and Rain Order at the beginning made his thinking spread, and he wondered if he could refine a magic weapon to detect the spiritual root by means of refining.

"If you can sense the spiritual root, then everything is easy to say."

Zhang Yunyuan's mind was whimsical, his magic weapon was wandering around Linyuan City, and once he met a mortal with a spiritual root, he would remind him.

"But how do you sense the spiritual root?" Zhang Yunyuan left the refining room, found a few children with spiritual roots, and began to study them while they had not yet fully exhausted their qi.

"The spiritual root is like an ethereal thing, which cannot exist somewhere in the body that is visible to the naked eye."

"The monk can use mana sensing after contact, and in addition to this, it is the array disk, and the array disk also uses the formation."

"What if I embed the formation into the artifact?" Zhang Yunyuan, who thought of the wind and rain, became excited.

However, as the days passed, he did succeed, but he also failed.

It is true that the magic weapon that was obtained at a great cost can detect the spirit root, but only that, the most important thing is that the consumption of spirit stones has not been reduced at all, and it is even more expensive than the family method.

Unless someone can continuously inject mana into the magic weapon, they can save some spirit stones.

But it's also a drop in the bucket, the little mana in the body of the Qi cultivator is probably exhausted before it lasts for less than a hundred mortal tests, and the foundation building cultivator, where does he have so much time to waste on this.

And even if it's a foundation, mana can't withstand the consumption all the time.

In this way, Zhang Yunyuan spent three months in failure after failure.

One day, three months later, while studying a child, the latter suddenly breathed into his body.

Seeing this scene, Zhang Yunyuan was stunned in place, and then flew to his refining room.

A few hours later, Zhang Yunyuan walked out with a metal ball in his hand.

"Come, touch it with your hand." Find a mortal who he is sure to have a spiritual root but has no qi into his body, and directly command.

A small hand timidly stretched out and touched the metal sphere, and a reddish light slowly lit up on the surface of the ball, but the next moment the light disappeared, as if everything was an illusion.

"It's hot." The little girl in front of her looked at Zhang Yunyuan and said with a somewhat fearful expression.

A talisman appeared in his hand and stuck it on the other party's body, Zhang Yunyuan said, "Go on." ”

A reddish glow lit up and continued to bloom on top of the metal ball, this time, for dozens of breaths.

As a foundation building, Zhang Yunyuan could clearly sense that when the little girl's palm touched the ball, the pure aura imprisoned by the magic weapon inside the ball seemed to have found an outlet, and it was integrated into the little girl's body through the palm of his hand.

Then he collided indiscriminately in the meridians and dissipated between heaven and earth, merging with the aura of heaven and earth.

took out a spirit stone, and the ball in his hand also revealed a small opening under the control of mana.

Stuffing the spirit stone inside, Zhang Yunyuan began to look for the next target, until all the mortals with the spirit root had been tested, and he began to test the results from other mortals.

"Sure enough, mortals without spiritual roots can't come into contact with those pure spiritual qi."

"The spiritual root is the portal, and with the portal, the blocked aura can enter and exit freely."

He knew very well what the effect of the magic weapon in his hand was, imprisoning the aura, purifying and dispersing the aura, there was no other use, any monk could do this, because this was the instinct of cultivation.

But at this moment, it was used by Zhang Yunyuan to detect the spiritual root, and the effect was remarkable.

"If the time is properly controlled, then the loss of spirit stones is almost negligible, and if it is placed on a large-scale inspection of mortals, it can reduce the loss by at least seventy percent."

If it is just a mortal, it will not attract the aura in the magic weapon, and the aura in the magic weapon can only wait for time and disappear.

The aura produced by the devouring and refining of a spirit stone can last for half an hour before it completely disappears.

And how many mortals can be touched in half an hour? Thinking of this, Zhang Yunyuan became excited.

"Notify other cities to postpone testing first, and wait for Linyuan City to see the results first."

Without hesitation, Zhang Yunyuan directly contacted the family and the surrounding cities, and then Linyuan City once again set off a climax of testing the spiritual root.

The immortal heart that has been measured before, and the immortal who has not been tested also came with the idea that the destiny is in me, after all, the people of Linyuan City have been familiar with the existence of immortal masters over the years, and they have infinite yearning for those immortal masters whose natural status crushes mortals.

Under a large number of tests, some lucky ones inevitably appeared, and what happened unexpectedly was that there were dozens of people who could cause changes in the spirit measuring ball, but there was no obvious color.

Zuo Qiu Zhuo also looked strange when he told Zhang Yunyuan about this, "These people don't seem to have spiritual roots in their bodies, but they can absorb spiritual energy. ”

Zhang Yunyuan was a little frightened, and immediately thought of the original Feiyan, could it be that these are wild immortal cultivators?

However, when he tested it himself, he was relieved, "Fortunately, it's not so perverted." ”

"It's not that these people don't have spiritual roots in their bodies, it's just that their spiritual roots are defective."

"The spiritual root in the ordinary human body has five elements, and the attributes of the five elements more or less determine what kind of attribute exercises are suitable for cultivation, but these people are different, their spiritual roots and five elements are lacking, resulting in the spiritual root not being visible, and it is normal if you can't find it, if you don't know that they caused the change of the spirit measuring ball, I won't find out."

"Some of the five elements are missing one, and some of the five elements are missing four, which is also a talent gap for their groups."

"Those who lack one may have the opportunity to cultivate to the early stage of Qi cultivation, and those who lack four ...... I'm afraid it will take a lifetime to induce qi into the body. ”

Looking at these people in front of him, Zhang Yunyuan felt that they were like those mortals who were born with disabilities, but the latter was mutilated by the physical parts, and what they were mutilated was the invisible spiritual root.

"Others can be included in the family, as for these pseudo-spirit roots......"

"Give them the law to induce qi, and tell them that if they can successfully practice qi, they can come and do things for my Zhang family."
