As for those techniques, the "Concealment Technique" and the "Sound Transmission Technique" were both auxiliary spells similar to the "Heavenly Eye Technique", and anyone could learn them as long as they knew a little about mana, so Han Li was very easy to get started.

Among them, the sound transmission technique was a rune that Han Li had seen several times and had to use the "Transmission Notes" to use.

The "Concealment 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. This spell is a bit of a chicken nature, because the "Heavenly Eye Technique" can easily break it, and it can't hide the eyes and ears of other immortal cultivators at all.

"Quicksand" and "Freeze" are both regional spells, one that can turn earth into sand where mana can reach, and the other can make water condense into ice.

The power of these two spells depends entirely on the depth of the caster's mana. If a person with great magical powers comes to exert it, it is not impossible to turn thousands of miles of fertile land into a desert and condense the Yangtze River into a glacier.

The reason why they are classified as primary and lower-level spells is only because these two spells are relatively easy to learn, even low-level immortal cultivators in the Qi refining period can easily learn them, but because of the limitation of mana, the small range is pitiful.

Han Li had a hard time learning these two spells, but after he suddenly broke through to the ninth layer and doubled his mana compared to before, these two spells were also very handy at once, and he could turn a place the size of a table top into sand or ice at will, which made Han Li very excited for a while.

As for the remaining few spells, Han Li couldn't comprehend them for a while, so he had no choice but to wait for them to be slowly refined and studied later. Because the Tainan Society was coming to an end, the young immortal cultivators who came to participate in the transaction finally reached their peak in the last two days of the Tainan Society.

At this time, the Grand Exchange Square where Han Li was located was crowded with more than 2,000 immortal cultivators, and the number of people who came out of the stall had increased several times compared to 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.

Han Li smiled bitterly, he found that even though he had entered the ninth layer, among so many immortal cultivators, he could only rank in the middle stream, and there were still many people above the ninth layer!

Han Li didn't have any spirit stones now, and there were very few pills, so he didn't have any idea of Taobao, he just walked along the flow of people from stall to stall. 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.

Not to mention that this way sounded, it really opened Han Li's eyes, and he learned a lot about some magic weapons and materials. For example: a dart weapon that can automatically chase the enemy, a gourd that can breathe fire outward, a long knife that can cut people and freeze people, the eggs of silver-winged ants can be used to make medicines, the scales of a century-old clemat snake can be forged, and so on.

The more Han Li listened, the more interesting he became, and before he knew it, he had come 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 more than enough!"

"What's the use of me asking for this fragment? I can still find a monk in the Dan stage and can't refine it!

A fierce quarrel came from a booth in front.

"Fragments of magic weapons?" 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 has appeared in this Tainan Valley, even if it is just a fragment, it is a miracle, making these immortal cultivators itch like cats that smell fishy.

"Where?"

"Let me see!"

"Is this the magic weapon?"

"Tsk!

"That's it!"

......

Because Han Li was relatively close to that stall, and because his skills were already much more agile than ordinary immortal cultivators, he was able to grab a good position in the inner circle and see 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, thick hands and feet, and at a glance, he thought that a farmer in a field had mixed into the Tainan Valley, but anyone who had seen this mana's mana with the Heavenly Eye Technique couldn't help but gasp. This black man is actually a tenth-layer master.

"Competing with this one, isn't that looking for death?" Some immortal cultivators secretly marveled at themselves, and their eyes fell on the stall owner. The stall owner is a very ordinary man in Tsing Yi, with only seven or eight layers of mana, but in the face of the man in front of him, there is no fear on his face.

Someone noticed that the stall owner's collar was embroidered with a leaf-shaped pattern, and it was only then that the immortal cultivators suddenly realized. It turned out that this was a disciple of the famous Qin Yeling Ye family of the immortal cultivation family, no wonder he was so pervasive.

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 did not match 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 silver mouse came out of it.

"The first-level demon beast eats the golden rat!" Among the immortal cultivators who were onlookers, someone called out the name of this rat, which caused a small commotion.

"It's really worthy of being a master of the tenth layer! I can even catch a first-level demon beast!" many people couldn't help but think secretly.

At this time, the black man picked up the piece of "cloth" and put it on the silver rat!

As a result, a miracle occurred! The silver rat 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 suddenly grabbed the same place, and an extra piece of "cloth" appeared in his hand, and the white mouse immediately showed its tracks.

And not only living things, but dead things have the same effect. ”

After saying this, the man took out an inch-long, aura knife and put it on the ground, and covered the "cloth" again, but the same disappeared without a trace, and there was no trace of aura exposed.

"It's amazing!"

"Can be invisible!"

"Tsk!

......

The onlookers began to talk about it.

"Well, it's definitely worth the money in exchange for your bowl!" the man said to the stall owner after taking off the "cloth" again, putting away the knife.

"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 Yudan 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.
