Mu Ping stretched out his hand to tear open the cowhide bag, and a dark brown wooden box was grabbed by him, and when he opened the wooden box, a palm-sized, milky-white fluorescent, and crystal clear stone appeared in front of his eyes.

"Spirit stone, and it's a medium-grade spirit stone!"

A comfortable feeling immediately permeated his whole body, and Mu Ping almost jumped up, this feeling was like drinking a cold carbonated drink on dog days, and every pore of his body was ironed.

"No wonder Li Zhanyuan's superiors regard this piece of white fluorite in their eyes as so golden, it turns out that this is a medium-grade spirit stone containing a lot of attributeless aura!" Mu Ping thought that it would be great if they could take out a low-grade spirit stone, but he didn't expect it to be a medium-grade one, you know, the value of a medium-grade spirit stone is equivalent to a hundred low-grade spirit stones, and it is also a loss that they don't know the goods, otherwise how could they come up with such a shocking thing? You must know that a medium-grade spirit stone may not be anything in the cultivation realm, but in this earth in the era of the end of the law, it is a priceless treasure.

With this medium-grade spirit stone, Mu Ping was confident that he would improve his cultivation to the ninth layer of the Transformation Tree, and it was not impossible to raise it to the first layer of the Solid Tree.

He faced the morning sun, sat cross-legged, held this spirit stone in his right hand, and the Nine Wood Divine Technique was also slowly transported. The aura in the Zhongpin Spirit Stone was so clean that it was almost transparent, and it continued to nourish his meridians, and after wandering for a week, it fell into his dantian.

Every cell in his body was like a black hole, greedily devouring the essence of the aura. In less than half an hour, the wood aura he had lost was replenished. And that spirit stone only used less than a millimeter, which was completely negligible.

"This is really a good thing!" Mu Ping had never felt so eager for the spirit stone as he did today, his face was red, his body was very light, and the dantian and every meridian were bulging, and a feeling of outburst arose spontaneously, he knew that this was touching the threshold of the fourth layer of the transformation tree.

"Break it for me!" He gritted his teeth, let out an angry roar in his heart, "quack", as if a membrane had been washed away in his body, and the wood aura in the meridians finally found an outlet and rushed out. He felt that his dantian had expanded more than a circle, and his meridians were even thicker and tougher.

"Puff!" As if causing a chain reaction, five more meridians in his body were penetrated, and the Wood Spiritual Qi Circulation Great Zhou Tian suddenly expanded. And the spiritual power he originally consumed was also replenished to the peak, and there was a slight surplus, and the spiritual power radiated out, which could easily cover a radius of fifty meters, that is to say, within the scope of his spiritual power, even if two ants fought, they could be captured by him.

"Finally the fourth layer of the tree?" he smiled slightly, but he did not stop absorbing the aura, dealing with the bald black armor and the unknown threat in the ancient tomb of Li Jiawan, the fourth layer of the tree can barely protect itself, if you want to achieve an overwhelming advantage, this cultivation is far from enough, this mortal planet is full of uncertainty, he doesn't want to capsize in the gutter because of his slackness.

He closed his eyes and concentrated, and then continued to absorb the aura in the spirit stone.

If it took him only half an hour to go from the third layer of the Transformation Tree to the fourth floor, it took him almost two hours to step into the fifth layer with half a foot from the fourth layer to the peak of the fourth layer of the Transformation Tree.

"It's still a little bit short!" Mu Ping shook his head and stopped cultivating, although it was the lowest stage of the Transformation Tree, he also knew the truth that if he wanted to be fast, he would not reach it, how could he say that his body was still too weak, if it was his original body, let alone the fifth layer of the Transformation Tree, even the peak of the ninth layer of the Transformation Tree could be easily reached.

Seeing that the palm-sized medium-grade spirit stone went down another centimeter or so, shrinking a large circle, leaving only half the size of a palm, he was also speechless for a while, although he knew that the more he cultivated in the future, the more aura he needed, but he didn't expect that he could harm the aura so much. If this continues, this medium-grade spirit stone, it can be said that it can help him improve to the first layer of the real tree, but it is difficult to say whether he can cultivate to the ninth layer of the transformation tree. In the final analysis, it is because there is too little aura on this planet.

He carefully put the remaining spirit stones into the wooden box again, and put a layer of sealing and prohibition on them, then put them aside, and then took out the gold nugget that emitted a pale yellow light.

It is relatively simple to create a golden needle, although the peak of the fourth layer of the transformation tree has not yet formed its own natal flame, but his wood aura can concentrate a little and slowly melt anything, this is the domineering of refining.

He clasped his hands together and tightened the grip of the piece, which was an inch long and half an inch wide. The gold nugget with a thickness of a quarter of an inch was held in his hand, and bursts of white mist steamed up from his hand, and the gold nugget turned into a pool of gold water at a speed visible to the naked eye, he held the gold water in his left hand, and his right hand was linked, and a piece of gold wire that could be seen by the naked eye was pulled out by him, and the index finger of his left hand was everything, and the gold wire became two hundred thin lines, and his right hand was crushed, and two hundred gold needles were already made, but this was far from enough, the gold nugget turned into gold wire was only the first step, and the most difficult thing was to use spiritual power to engrave the formation on each gold needle that was not much thicker than a hair。

Two hundred golden needles, it also took him nearly an hour, this is the completion of the carving, if it is not for his promotion to the peak of the fourth layer of the tree, the spiritual power has been greatly restored, and the depiction of the formation on the golden needle will have to tire him out, fortunately, although some spiritual power is consumed, but the golden needle is still completely portrayed by him. One by one shimmering in the sunlight, he threw it casually, and a golden needle quietly sank into the stone that had been cut off by him, and with a "pop" sound, a hole in the center of the stone was bursting out of a bowl-sized hole, and with a "click", the stone cracked a three-inch-wide crack.

Mu Ping nodded, he was very satisfied with the gold needle he had refined, and with a move of his hand, the soft gold needle returned to his hand, and it was as sharp as usual, and it was not damaged at all.

If someone finds out about this scene, they must think that this is not in line with science, but there is nothing in the world that is in line with science, and there are not so many unsolved mysteries?

"In the future, this set of gold needles will be called bursting. He put it away satisfied.

It took another twenty minutes for him to refine three necklaces and a gold piece, the three necklaces are not thick, although the gold is outdated, and it is still a little cheesy in the eyes of the rich, but the necklace refined by Mu Ping is different, the golden yellow reveals such a noble and elegant, especially the heart-shaped pendant, which reveals a touch of agility.

Of course, there are defensive formations carved on them, which can withstand three attacks. At present, his strength is limited, and he can't carve a decent counterattack formation, if he cultivates to the first level of the real tree and carves a counterattack magic weapon, even a third-level demon beast like bald black armor will have to be hated.

Even so, if they meet last night's thin monkey and wild wolf, six sons and three people, they don't want to break the defense of this chain, even if Liu Bing is in the number of five or five.
