Then, Xiling Lan softened her voice again, "As for the fairy couple, I don't seem to be in a hurry, let's leave tomorrow, right?" Traveling around the country, it must be more fun than Chu Feng Country outside, this group of people in Chu Feng Country are smaller than needles, and they fight ...... all day long."

Chu Tianmu said meaningfully, "Immortal couple, should you get married first?" Otherwise, when traveling, sometimes lonely men and widows, **, in case ......"

Xiling Lan grabbed a handful of jewels and threw them towards Chu Tianmu, "No, labor and management are not yet adults!" ”

Sad 14-year-old, sister, just grow up quickly. （）（）

Suddenly, this handful of jewels was thrown over, and there were several rings made of gold and jade, which were blocked by Chu Tianmu and fell to the ground, making an extremely crisp sound.

There is also a long, distant echo. （）

Xiling Lan sighed and picked up the ring.

"What is this ring made of? Why is the sound so crisp and resonant? She asked Chu Tianmu.

Chu Tianmu replied, "This kind of ring looks like it is made of gold, but it is actually a kind of chalcedony, which has grown in the deep mountain belly cave for more than a thousand years, it is as hard as a stone, and it is much more valuable than gold. (Immortal Cultivator)"

Xiling Blue's eyes lit up.

"Great, that's it! However, there are still a few improvements to make the sound more crisp and pleasant, to increase the strength of the sound, and to set a few beat points......"

How smart is Chu Tianmu?

"Girl, don't you want to be a liaison whistle or something?"

"You're smart. () The range of the whistle is too small, at most it can only be a few miles in radius, and in critical moments, it is too late to whistle, and it is easy to be exposed, if you get a special sound transmission ring will be very good, when using, you only need to gently pull the mechanism on the ring, you can transmit the sound, and the range is wider than the whistle......"

Chu Tianmu was puzzled, "However, the ring is already small enough, how can you add a fine mechanism to it?" It has always been pronounced as a collision of two. （）”

"Look at me, just get all the things of this material back, whether it's a ring or something else......" Xiling Lan pursed her lips.

"A one, B two, C three, D four, out of the ranks! One box per person, open and find. After Chu Tianmu finished commanding at the air, he first looked for it next to Xiling Lan.

The four leaders of the guards swept in from outside the courtyard with the speed of the wind, and said in unison, "Yes! ”

Look for it.

※※※

More than 30 rings were found in more than a dozen boxes, a dozen bracelet-shaped rings, and two rings.

Xilin Blue is extremely satisfied.

Chu Tianmu, this fiancé, is really good, a good family man, and has the characteristics of a prosperous wife! Ahem!

I have been busy for more than half a month, because the work is too delicate, and Xiling Blue is also the first time to make it according to the content of the fragments of the mechanism, and almost half of the materials have been lost.

I made ten communication rings, tried it once, and the sound quality was extremely clear and long, several times larger than the range of the whistle, and in a quiet environment, it could be heard clearly within a radius of ten miles.

Xiling Blue also designed several gears, the first gear is positioning, the second gear is danger, and the third gear is evacuation. The sound of the three gears is different, which is very good, and the eyes of the guards are straight, and they want to rub one of them.

Chu Tianmu was curious about where did Xiling Blue's such a delicate craftsmanship come from? And he has seen all the traps laid up and down the Four Princes' Mansion these days, and its subtlety is definitely not something that Chu Mingtang learned.
