After Niu Shan's long-distance test, the signal banner can still emit misty spiritual waves 30,000 miles away from Shuzhi Mountain.

When we reached the northern edge of Dongsheng Shenzhou, the array map on the signal banner dimmed.

However, after Niu Shan inputs magic power to bless the signal banner, the hand talisman held in his other hand returns to normal use.

In this way, after more than half a month of performance testing, the hand talisman, which integrates various magic arrays such as voice transmission, audio-visual, message, water mirror recording, etc., has finally officially started to be put into use.

In the hand talisman, the user can use mana to stimulate the corresponding rune entries for use.

To transmit sound, you only need to stimulate the sound transmission note, and audio-visual inspire the audio-visual runes of thousands of miles.

Messages are divided into one-way messages and group messages.

After the user inspires the musical note and then checks a single number or multiple number, he can leave a one-way or group message.

Similar to voice chat.

The final water mirror recording is made by combining Taoist water mirror technique and the method of making photoreal stones. After using mana to stimulate it, aim the jade talisman at the scene you want to enter, and you can record it.

After recording, you can save it yourself or transmit it through audio-visual functions.

If you break them apart, these functions on the hand talisman are not worth mentioning to monks, and they are all ordinary magic tricks.

Even if it is combined together, it is just an ordinary comprehensive communication technique.

However, the communication hand talisman is higher than these techniques in that it can enable multiple users to communicate with each other. The traditional sound transmission jade slip and audio-visual talisman rules can only be connected in pairs and cannot be interconnected.

With this alone, the two will be very different.

Compared with the magic of unilaterally transmitting messages, communication hand talismans that can communicate and operate easily will undoubtedly be more popular among practitioners.

After the communication hand talismans of about a hundred slaps were prepared, when distributing them to the demon cultivators, Zhu An discovered another unexpected problem.

These jade talismans as big as palms can be used as decent when used for demon cultivators with human-sized physiques such as fox demons, monkey demons, snake demons.

But once you encounter giant wood spirits like the Wood Demon Clan or the Elephant Demon of Baixiangling, such a giant demon cultivator with a large body, the jade talisman as big as a palm is obviously not suitable for use.

Looking at the communication hand talisman that was about the size of the "finger nail" clamped by the fingertips of the elephant demon, Zhu An had no choice but to start refining the "communication jade plate" and the "communication jade stele" with the deer-angled fairy Yun Tingzi. In the end, he even tried his best to dig out a huge piece of green spirit jade from the mountain and make it into a super-large communication jade stele that is about two feet wide and five feet high to be used as the communication hand talisman of the old leader of the Wood Demon Clan.

In this way, after each of the gentlemen and the great demons placed a hand talisman that suited their body proportions, Zhu An began to send the talisman out.

First of all, the Wood Demon Clan who helped Shuzhi Mountain.

After the wood demons left in Shuzhi Mountain learned to use hand talismans, Zhu An asked them to return to the Wood Demon clan with more than ten larger gifts and an extra-large hand talisman.

After that, the psychic little wood monsters in their clan can use the hand talisman, without having to go out and take root in the clan, and can comfortably listen to the text lessons taught by Mr. Wentang of Shuzhishan. After learning, the little wood monsters who cannot speak can use branches to carve texts on the land to communicate, which can be regarded as thanking the Wood Monster's last assistance.

The other two places like the Moming Cave in Baixiangling have also been sent out with corresponding sizes.

In this way, several demonic mountains and demon caves can not only facilitate contact, but also deepen their friendship and form a trend of mutual continuity.

After finishing all this, Zhu An came to the library and found Bai Yu.

After briefly introducing the function of the communication hand talisman, Zhu An said: "With this hand talisman, Bai Nian can contact his parents, brothers and sisters from time to time. So I would like to ask my second uncle to help me and send a few hand talismans to the White Tiger clan."

Bai Yu played with the jade talisman in his hand with great interest. After Zhu An finished speaking, he looked up and said:

"I don't plan to go back in a short period of time. Your hand talisman is quite interesting. You can give it to me first. After a few years, I will take the hand talisman back."

On the side, Zhu An asked in confusion: "If you don't go back for a short time? Where are you going?"

Bai Yu looked at Zhu An for no reason and said, "Just here, where else can I go?"

Now it was Zhu An's turn to feel inexplicable.

There are only so many books in the library. Even if you read one page a day in the past two years, you should have finished reading it? There is nothing else fun in Shuzhi Mountain, so why are you still here to do?

Zhu An thought for a moment and said, "How about this, you give me a token, and I will send other demons to visit and send the jade talisman. What do you think?"

"It's OK."

After thinking for a while, Bai Yu agreed to Zhu An, then took out a bone tooth and handed it over.

"You can enter the White Tiger Clan with this tiger tooth. As for the location, go back and ask your second sister and let her tell you."

After saying that, Bai Yu suddenly thought of something, and quickly called Zhu An and said without any explanation: "Give me another talisman with you."

Zhu An was stunned when he heard this, and then smiled and said, "Okay!"

As he said that, Zhu An took out a communication talisman made of blood jade and handed it to Bai Yu.

"No, change another one, this color is too bloody." Bai Yu frowned slightly.

Upon hearing this, Zhu An took back the blood-colored jade talisman and took out another hand talisman made of black jade.

"This color is not good, change it.

This style is too ugly, change it.

Too thick, change.

If the color doesn't match, change..."

After changing four or five consecutive times, Bai Yu was still dissatisfied.

On the side, Zhu An's eyelids twitched, and finally he simply poured all the dozens of communication hand talismans in the storage bag onto the table.

Standing next to him, Zhu An looked at Bai Yu who was screening the jade talisman like an aunt who was picking cucumbers.

After a while, Bai Yu finally picked up the jade talisman that was suitable for both color and size.

Zhu An looked at Bai Yu with some surprise.

He didn't expect that the other party liked the jade talisman made of pink spiritual jade.

When Zhu An put away the unselected jade talisman, he felt emotion. He didn't expect that Bai Yu was so arrogant and liked this kind of girlish jade talisman.

After leaving the library, Zhu An went to find Hyacinth again.

Before, Hyacinth had been to Jilei Mountain with him. Now Niu Shan wants to contact his old friend Jilei Mountain with his hand talismans, so Hyacinth is the most suitable candidate for giving talismans.

The whole mountain is the most leisurely.

After splitting half of the remaining hand talisman and giving it to the hyacinth, and teaching it how to use it, Zhu An gave it a seven-turn golden elixir as a reward.

If you want the horse to run, you have to feed some grass.

Hyacinth has been stuck in the perfect realm of the earth immortals, and this golden elixir is enough for it to break through to the true immortal realm.

"After the cultivation level is broken, go to Jilei Mountain to send the hand talisman. Do you understand?"

After stroking the horse mane of the hyacinth, Zhu An gave it Niu Shan’s demon card and some worship gifts prepared by Niu Shan.
