In the blink of an eye, it has been half a month since the discovery of the Yangyuan stone vein.

Lin Mu did not take it to his home all day long as before in the past half a month, but went to the trading workshop every day to buy some elixirs of more than four grades.

The purchase of the elixir was only incidental, his real purpose was to find something, but unfortunately he still didn't find it after looking for half a month.

On this day, Lin Mu still came to the trading fair as usual.

"Hey, did it finally show up?" Lin Mu was secretly happy in his heart, he found a spiritual power fluctuation, and there were not many things in the trading workshop that could have spiritual power fluctuations.

Lin Mu quietly walked to a stall, which was full of dazzling goods.

"How do you sell this Aoki spirit stem?" Lin Mu asked, holding the Aoki Spirit Stem in his hand, but his attention was on an ancient tree covered with moss next to the Aoki Spirit Stem.

This ancient tree is the ancient tree that records the method of condensing the ancient whirlpool rune, and Lin Mu has been wandering around the workshop for more than half a month, just for it.

"Fifty Yang Yuan Stone!" The stall owner wore a black hat and said in a salty and non-salty manner.

"What about this ancient tree?"

"One hundred Yang Yuan Stones."

"Such an ancient tree is actually more expensive than a fourth-grade elixir?" Lin Mu pretended to be surprised and said, although he was not short of this money, he didn't want to be treated as a fat sheep.

"The vague runes on this ancient tree should be related to the talisman, if it weren't for the fact that there was no talisman in Qingyang Town, I would have sold more than one hundred Yang Yuan Stones." The stall owner said lazily.

"Two together, how about a hundred Yang Yuan Stones?" Lin Mu said.

"One hundred and fifty yuan, if you want to buy it, you can buy it, and if you don't buy it, you won't be reluctant." The stall owner said, looking like he likes to buy but not buys.

"Okay!" Lin Mu said, took out fifteen Yang Yuan Dan, and threw them to the stall owner.

These Yang Yuan Pills were still condensed by his boredom in the past few days, and when the Yang Yuan Stones were mined, Lin Mu looked at them and took some of them casually, purely for fun.

"Hehe, it's bold enough!" The stall owner showed a touch of joy.

Lin Mu felt that he was still not suitable for bargaining, if he insisted for a while, the other party might really agree to sell him a hundred yang yuan stones.

However, Lin Mu didn't care anymore, he now took a casual breath of ten pure yuan pills, which was equivalent to one thousand yang yuan pills, rather than spending time and more on the stall owner, it was better to take a few more breaths.

After obtaining the method of condensing the ancient vortex sigil, Lin Mu was also happy to trade and returned home.

Psychic Technique: None

In this half a month, Lin Mu has improved his spiritual power cultivation to the Four Seal Talisman Master, and his Yuan Li cultivation has also been upgraded from the original small Yuan Dan realm to the small consummation of the Yuan Dan realm.

"You can go up again!"

It only took 900,000 pure Yuan Dan for Yuan Li cultivation to be promoted from the Small Yuan Dan Realm to the Yuan Dan Realm Small Perfection, while it took 900,000 pure Yuan Dan for the Spiritual Power Cultivation to be promoted to the Third Seal Rune Master, and 1.2 million Yang Yuan Dan for the Fourth Seal Rune Master.

For the current Lin Mu, a few days is enough.

Now that he has accumulated more than 1.8 million pure Yuan Dan, both Yuan Force cultivation and spiritual power cultivation can be improved, but Lin Mu still chooses to improve his spiritual power cultivation first.

With a slight click, the number of Pure Yuan Dan suddenly decreased by one and a half million, and the spiritual power cultivation also changed from the previous four-seal rune master to a five-seal rune master.

"The Five Seal Runic Master is comparable to the Great Perfection of the Yuan Dan Realm, plus the cultivation of Yuan Li, now in the entire Yan City, no one is my opponent."

Lin Muqing felt that with just one movement of his mind, he could exert a huge amount of power, and when used with Yuan Force, it was enough to defeat ordinary modeling realm powerhouses.

The city lord of Yancheng has just entered the modeling realm, and he has not even reached the modeling realm.

"After the Five Seal Rune Master, there is a Spirit Rune Master, but now there is no hurry to improve, and after cultivating the Yuan Force to the Great Perfection of the Yuan Dan Realm, accumulate some pure Yuan Dan to exchange for Shadowless Needles." Lin Mu thought in his heart.

"Big brother, I've cultivated my spiritual power." At this time, Lin Dong ran into Lin Mu's room excitedly.

Half a month ago, Lin Mu taught Lin Dong the method of spiritual power cultivation, Lin Dong was extremely interested in the cultivation of spiritual power, and he practiced very hard.

"Yes, but it's nowhere near the condensation sigil." Lin Mu nodded.

"Big brother, do you think that everyone is like you, and you can condense the rune after a few days of cultivation, otherwise, how can there be no rune master in Qingyang Town." Lin Dong glanced at Lin Mu.

"I have a way to increase your mental power a lot." Lin Mu said with a smile, he didn't cultivate by himself, but purely relied on the system to improve.

"Big brother, what's the solution?" When Lin Dong heard this, his eyes lit up.

"I'll teach you a method of condensation, which I just found from the Workshop Market." Lin Mu said.

"Big brother, there will be some good things in the trading workshop, you can teach me another method of condensation." Lin Dong said with a doggy smile, he knew that the things that came out of Lin Mu's hands were all good things.

"If it's not a good thing, can I see it? If you want to learn, you can learn, and if you don't learn, forget it. Lin Mu said angrily, although the Ancient Vortex Talisman Seal is not as good as the Thunder Heavenly Seal, it is made by imitating the Devouring Ancestral Talisman, which will be of great help to get the Devouring Ancestral Talisman in the future.

"Learn, I'll learn!" Lin Dong hurriedly said.

"Take it!" Lin Mu handed over the ancient wood he had just gotten to Lin Dong.

"Big brother, how are you going to get this?" Lin Dong looked at the ancient wood in his hand, but he didn't know what to do next.

"It's okay to immerse yourself with mental power." Lin Mu said.

According to Lin Mu's words, Lin Dong mobilized his weak spiritual power and immersed himself in the ancient tree, and suddenly the ancient tree emitted a faint luster, the luster condensed, and finally turned into a beam of light, projected onto Lin Dong's forehead.

A stream of information quickly poured into Lin Dong's mind.

The ancient vortex sigil, the method of condensation.

After a while, Lin Dong exhaled lightly, and the information in his mind had been completely digested.

"Big brother, what about the method you said to quickly increase your mental power?" Lin Dong asked, as long as the rune seal is condensed, he can be regarded as a seal talisman master.

"Come with me." Lin Mu said.

"Big brother, where are we going?" Lin Dong asked, and immediately followed.

"Temuzhuang."

"Is there any treasure in Ironwood?" Lin Dong's eyes flashed with a gleam.

"You'll know when you get there."
