As for those techniques, "Stealth Technique" and "Sound Transmission Technique" are auxiliary spells similar to "Heavenly Eye Technique", as long as you know a little about mana, anyone can learn them, so Lin Hao can easily get started.

Among them, the sound transmission technique is a spell that Lin Hao has seen several times and must use the "sound transmission note" to use. In fact, Lin Hao has always wanted to learn this sound transmission technique, this thing is too practical and convenient, after all, he was used to using the phone before, and he has been in this world for so many years, and the previous communication method could only rely on letters to communicate, which was slow and laborious. Well, now that I have this sound transmission technique, it is much more convenient, and I don't have to spend money on phone bills. Lin Hao thought happily.

"Stealth technique" is a pure ordinary spell, which is to let the spiritual power attach to the whole body, so that the body becomes a protective color similar to the surrounding environment, which is not easy for people to notice.

And the remaining few spells, Lin Hao couldn't comprehend for a while, so he had no choice but to wait for the future to slowly scrutinize and study, and the young immortal cultivators who came to participate in the trade finally reached their peak in the last two days of the fair.

At this time, the Grand Exchange Square was crowded with thousands of immortal cultivators, and the number of people who came out of the stall was several times higher than before, and most of them wanted to seize the last opportunity to sell all the items that had not yet been exchanged. And many high-level immortal cultivators who had been hiding there all this time also appeared, and they also wanted to take advantage of this opportunity to observe those fellow Daoists who might become fierce enemies.

Lin Hao smiled bitterly, he didn't have any spirit stones now, and there were few pills, so he didn't have any idea of Taobao, just walked over one stall after another along the flow of people. Wherever there are many people, they go wherever they go, just to listen to the comments and opinions of the immortal cultivators on the buying and selling of goods, so that they can gain a long insight.

This way it sounded, it really opened Lin Hao's eyes, and he learned a lot about some magic weapons and materials. The more Lin Hao listened, the more interesting he felt, and before he knew it, he came to the middle of the square.

"No, I don't want this thing from you, exchange it for other items!"

This is a fragment of a magic weapon! This material can be exchanged for your bowl! What use do I want this fragment? A fierce quarrel came from a booth in front.

Magic weapon fragments?" This voice that surprised everyone immediately caused the nearby immortal cultivators to blow up, and the water around the stall was leaked with a bang.

You must know that the magic weapon is something that low-level immortal cultivators dare not dream of in a daydream, but now that it will appear in this transaction, even if it is just a fragment, it is a miracle, making these immortal cultivators feel itchy like cats that smell fish.

Where?" Let me see!" Is this the magic weapon?" Because he was relatively close to that stall, and his skills were already much more agile than ordinary immortal cultivators, he grabbed a good position and saw everything in front of him clearly.

I saw that in front of this stall, there was a man of twenty-seven or eighteen, this man had dark skin and thick hands and feet, but anyone who had seen this mana with the Heavenly Eye Technique couldn't help but gasp. This black man is actually a tenth-layer master.

In the stall between the two men was a yellow bowl with a strange pattern and a small piece of translucent cloth-like object.

The rag-like object, crumpled and unevenly around it, looked like it had been gnawed by a dog. The only thing that catches the eye is that it flashes white light from time to time, which is somewhat peculiar. After seeing the real thing, many of the onlookers were disappointed, and it was very inconsistent with the image in their minds.

"This fragment is amazing! as long as the object covered with it will be invisible immediately, and not a trace of aura will leak out, and it will not hinder the entry of aura from the outside. The black man had a cold face and explained loudly to the stall owner.

With that, he suddenly turned his cuffs down, and a small silver beast came out of it.

"First-level demon beast looking for spirit beast!" Among the onlookers of immortal cultivators, someone called out the name of this beast, it really deserved to be a master of the tenth layer! It was even a first-level demon beast that could be caught!" Many people couldn't help but secretly think. At this time, the black man picked up the "cloth" and put it on his body!

As a result, a miracle happened! The little beast and the "cloth" disappeared immediately. Even if many people look with the eyes of heaven, they find nothing.

The man was a little satisfied when he saw everyone's surprise. Then he grabbed it in the same place, and there was an extra piece of "cloth" in his hand, and the little beast immediately showed its tracks, and the man took out an inch-long, aura knife and put it on the ground, and covered the "cloth" again, and the result was that the same disappeared without a trace, and there was no trace of aura exposed.

The onlookers began to talk about it. How about it, it's definitely worth the money for your bowl!" The man took off the "cloth" again, put the knife away, and said to the stall owner.

"No, if you want to be invisible, just buy a beginner and mid-level Escape Talisman, and such a small thing, can I hide my head or let me hide my feet?" said the stall owner with a sneer, shaking his head.

"Didn't I tell you? This is a fragment of a magic weapon, either a monk of the Yu Dan stage or a monk of the Yuan Infant stage, not a monk of the same level, who can see through its concealment effect? How can the Escape Talisman compare with it!" the black man said angrily.

"I don't need this thing at all, why do you want it!" You still exchange thirty spirit stones or other equivalent items for this bowl!" said the stall owner coldly.
