Zhang Ning chose a prospecting task, which surprised Elder Wu extremely much, because the reward for this task was only five crystals.

Zhang Ning received a prospecting artifact from Elder Wu, a small drill bit that could drill into hard rock to take samples.

Of course, this artifact is expensive, and if it is lost or damaged, it must be compensated.

Zhang Ning took Mickey to a hill on the west side of Qingyun Mountain, which was still in the sphere of influence of the Qingxu faction, and Zhang Ning did not dare to leave the Qingxu faction rashly.

Zhang Ning communicated with the treasure hunt mouse for a while, and learned that the treasure hunt rat came and went freely in the soil, Zhang Ning let Mickey leave on his own, and let him explore first to find a suitable location.

And Zhang Ning took out a futon and sat under the tree to close his eyes and practice.

As soon as he settled down, he was shocked to feel a beating in his chest, and Zhang Ning found that the snail shell was constantly jumping, as if there was something inside that wanted to pop out. He hurriedly sank into his heart, and saw that the jar of pear blossom brewing was jumping on a rampage, and before Zhang Ning could make any move, the jar hit a stone table and shattered, and Zhang Ning found that the snail was entangled with an iron-black earthworm.

Where did the earthworms come from? Zhang Ning saw that the two insects had been fighting for a while and then separated, rested for a while and continued to entangle.

In view of the battlefield they just had, maybe they were grabbing wine and drinking? In the home field of the snail, the earthworm was not directly thrown out of the space, which shows that the snail deliberately released water, and in the snail shell space, it actually entered other living creatures, which can also be seen that this earthworm is extraordinary. The snail shell no longer beats, and Zhang Ning decided to wait and see what happened, and continued to close his eyes and practice.

However, the last jar of pear blossom brew has been reimbursed, and after finishing this matter, it is necessary to immediately purchase a large number of wines.

Two hours later, Mickey came back, and he was showing off to Zhang Ning with great vigour, Zhang Ning was happy in his heart, and praised it again and again.

After determining the direction, Zhang Ning came to the north side of the hill and began to drill with a magic weapon, and after half an hour, Zhang Ning felt that the efficiency of this magic weapon was too slow.

So, Zhang Ning sacrificed the scales, first used the scales to smash a mountain, then drilled a few holes, and then continued to bombard with the scales, the rocks broke and fell, and a passage was carved out in this way.

Zhang Ning communicated with Mickey a few more times, changed the direction three times, and after drilling the last few holes, he urged the scales to bombard - "Bang la la la" An echo sounded.

The dust settled, and a gap in the mountain appeared in front of Zhang Ning and Mickey.

According to Mickey's guidance, Zhang Ning found the gap in the mountain formed during this geological movement.

The void is narrow, the wall is steep and towering, and there should be a gap to connect to the outside world, and there is air circulation, so the air here is not turbid. Although the volume is small, Zhang Ning estimates that it is enough.

Zhang Ning took out a green willow root, inserted it into the soil under his feet, and then dripped a drop of "wind oil essence".

As a result, Zhang Ning almost felt that he heard the cry of the tree - "hum~~" suddenly, the roots of the willow tree with the thickness of the index finger expanded rapidly, branched, and penetrated deep into the soil. Then, the wrist-thick emerald green trunk rose from the ground, rushed straight to the top of the crevice rock, and stopped about a meter away from the top of the rock, and then, the trunk began to thicken at a rate of one centimeter per second, and did not stop until Zhang Ning's thigh was thick, and then, a "whooshing" sound was heard, and hundreds of branches were thrown out of the trunk. When the branches hang down, they emit an emerald green fluorescence, similar to the fluorescent green version of the Avatar Pandora's Tree of Life.

Zhang Ning happily sighed at the wonderful use of wind oil essence, and at the same time motioned for Mickey to start working.

Mickey expertly burrowed into the soil, and in a short time, pulled back dozens of fresh "glow sticks". Zhang Ning urged Mickey to continue, but who knew that Mickey actually refused, and admonished Zhang Ning with a divine thought, to give Biqingliu "recuperation", Zhang Ning originally wanted to squeeze the value of this tree dry, since Mickey, who is concerned about ecological balance, refuses, then forget it.

After Zhang Ning left the cave, he immediately came to Elder Wu's place.

Elder Wu pinched the tip of his beard and asked, "Why did you come back so soon?

Zhang Ning came to the table, handed back the prospecting weapon, and said, "The prospecting mission has been abandoned. Without waiting for Elder Wu to speak, twenty more green willow roots were discharged.

Elder Wu's hand shook and he pulled off a beard, and he stood up with a "surge": "The treasure search rat has stolen the roots of the tree again?

Zhang Ning said lightly: "This is the twenty green willow roots that I used to repay my debts. ”

Elder Wu glared at Zhang Ning, "What did you say?"

Zhang Ning continued to say patiently: "I found a wild green willow when I was prospecting, so these are my debts. ”

Elder Wu hurriedly asked, "Where is it?" If it is a spirit plant within the sect's sphere of influence, it is all owned by the sect!"

Zhang Ning sneered: "Of course I know this, after paying off the debt, I will inform Elder Wu of the location." ”

Elder Wu saw the rebellious meaning in Zhang Ning's eyes, he knew that if all the roots of the tree in Zhang Ning's hands were confiscated and private ownership was not allowed, it was not impossible, a mere third-level disciple of Qi refining, even if he wanted to destroy the tree in a fit of anger, Elder Wu could subdue him instantly. But the head of the Qingxu faction, Qing Xuan Zhenren, is quite generous to his disciples, and has not yet reached the point of killing chickens and taking eggs and exhausting himself to fish, he has recently been disliked by the head of the family because of the concubine, there is no need to provoke the head again, and Zhang Ning is involved in the matter of Elder Liu Feiyang, so he can't be moved easily.

Elder Wu's thoughts turned for only a moment, and then he grinned: "Of course, what Elder Xing of the Law Enforcement Hall said clearly is that it is okay to repay twenty green willow roots, so this part of the debt will be paid off." ”

Zhang Ning still didn't open his mouth after thanking him, Elder Wu's face sank, and he snorted, so he had to summon him to the Law Enforcement Hall in front of Zhang Ning and inform him that the debt was paid off.

After Zhang Ning thanked him again, he told Elder Wu the location of Biqingliu.

Elder Wu was extremely surprised, it was really unbelievable that the Spirit Tree growing so close to it was not known to the Qingxu Sect at all. After he summoned the medicine garden master, he personally went to check.

Zhang Ning didn't follow, but went straight to Menpaifang City - he still had dozens of "glow sticks" to sell!
