However, the last turmoil had some impact, and the relationship between Lin Hu and Qin Wan'er made her suffer a lot of criticism.

Zhong Ding and others not only framed the judge Zhang Zheng's seniors and wanted to ruin the reputation of the Super Fairy, but also started from her side to spread rumors and make people question the fairness of the audition.

If the main battlefield was not in this direction, the problem might have been more serious.

Being able to come over under this pressure made Lin Hugao look at it a few times.

The auditions have come to an end.

But there are still some small problems plaguing Lin Hu in the rematch.

In fact, this thing can also be passed, but Lin Hu wants to make it as good as possible, so he will be entangled in this problem.

There is no internet or TV in the Xiuzhen world.

In the case of large populations, full coverage is not reached.

Therefore, during the audition, four venues were divided to select fifty contestants, and the process was very long, divided into many sessions, and naturally took turns to watch.

But when it comes to the rematch, it is impossible to say that it is divided into many games and sold many times, so one ticket can be seen from the beginning to the bottom.

This is where Lin Hu is troubled.

He sat in his place, frowning, thinking about what could be done to solve the problem.

But the largest venue in White Tiger City can accommodate more than 100,000 monks is already the limit, and if there are some more arrangements, it will not even reach this number.

It is no longer possible to improve in this area.

Lin Hu rubbed his eyebrows, inevitably encountering this problem in terms of communication.

"You said that there is all that kind of black technology for identity identification, why don't you have a TV?" Lin Hu couldn't help but feel depressed.

The ancestor of the Guo family, who was called over by Lin Hu, sat opposite Lin Hu, and at this moment he heard Lin Hu nagging, and said something inexplicable, and couldn't help but be stunned: "What is that TV?" ”

"This ......" Lin Hu took a deep breath, thought about it and said: "It's to get a local scene to another party, so that more people can watch it, but it's a pity that the photo stone, otherwise the recording and broadcasting is also a road!" ”

There is no breakthrough in the research of the Shadow Stone for the time being.

What's more, the process of the rematch is very long, far from a matter of one or two hours, and the Lingering Stone has limitations, it can only cover a small area, if you want more people to see it, the investment is something that Lin Hu dare not imagine.

The ancestor of the Guo family frowned and said: "Let the scene of one place be seen by people in another place, do you mean the water mirror technique of the Yuan Infant Realm?" ”

"Alas......" Lin Hu was very distressed, but then he was shocked, and looked at the ancestor of the Guo family incredulously: "What did you just say, what kind of water mirror technique?" ”

"A technique that can only be used in the Yuan Infant Realm, a means used by the great sects to teach their disciples." The ancestor of the Guo family thought for a while and said, "It's not easy to say, so let's show you this, and you will probably understand." ”

The ancestor of the Guo family stood up and walked out as he spoke.

Lin Hu also walked out after him.

When he came to the wide courtyard, he waved his right hand, ran the exercises, gathered his own strength, and the aura around him jumped, and he was immediately attracted by him, and condensed a large water ball with a diameter of several meters in his hand.

This means that Lin Hu will be.

It is nothing more than a means of using spiritual power or true element, and condensing water balls is also an entry method.

Don't look at the huge water balloon of the ancestor of the Guo family, in fact, the reason is very simple, it is similar to what Lin Hu has learned, it is nothing more than that when the power is strong, it can be condensed even more.

He pushed forward with his right hand, and the water balloon suddenly turned into a water curtain, and the water curtain was even more connected from head to tail, like a track, constantly flowing.

Lin Hu's eyes almost widened.

it!

This imaging technology feels like a magnifying glass.

Completely magnified the scene in front of him several times, no wonder it is said that it is used when teaching disciples, after all, there are some sects with thousands of disciples.

The power of the master of the Yuan Infant Realm may be able to make everyone's voice hear.

But sometimes, it is necessary to do a demonstration in person, so this water mirror technique can magnify the actual object, and the disciples from a distance can also see the demonstration.

But as far as the picture is concerned,Because the water is flowing,So it looks a bit like a black and white TV,The pixels are not very high,But it can't stand up to the black technology in the cultivation world.。

Lin Hu said excitedly: "How big can this thing be, can it be clearer?" ”

The ancestor of the Guo family thought for a while controlling the water mirror technique and said: "In terms of my strength, a few hundred meters or a few thousand meters, it can be clear, but the bigger it is, the more difficult it is to control." ”

Liquids are fluid, after all, they are water-based spells.

It is impossible to say that it can be condensed, and if it condenses into ice, the effect will not be very good.

Lin Hu's brain quickly earned, and when he thought about it, he laughed wildly.

"Magnifying glass, it's actually very simple, why didn't I think of it, there are so many means in the cultivation realm, if you really want to do it, there won't be too much difficulty, Lao Guo, you really helped a lot, come on, come and consult with me!"

Lin Hu took out a pen and paper and began to write and draw on the stone table in the courtyard.

The ancestor of the Guo family looked at Lin Hu's movements while maintaining the technique.

Everyone understands the truth of the magnifying glass.

It's just that Lin Hu didn't think of this for a while, and he wanted people outside the field to hear the sound in the field, which is not difficult, and some magic weapons can achieve sound amplification effects.

But if you want people outside the field to see what's going on inside the field.

A simple convex lens will definitely not be able to achieve this effect.

However, you can use the principle of a telescope to adjust the details, build a mirror inside the stage, and then build a mirror in the outfield of the venue.

In this way, the image can be transmitted to the outside.

In this way, there will be more people who can see what's going on in the field.

Lin Hu immediately started and began to conceive.

Fortunately, at the beginning of the rematch, there is still a period of time, which is enough for Lin Hu to squander.

The ancestor of the Guo family finally figured out Lin Hu's thoughts, and immediately summoned the masters to come over and start researching.

What you need, you can use magic to make ice cubes, but this thing doesn't last, it needs to be constantly replenished by the master, crystal stones are precious for ordinary people, but for monks, it's really not a valuable item, most of them are used as decorations, and it's easy to get.

It's just a day and a night's work.

There is already a proper way to deal with it.

No one did it before, because where did the master need these things to assist, a water mirror technique is enough to squander, that is, it will be used on some teaching occasions.

Where there is demand, there is motivation.

Now Lin Hu needs this aspect, and the plan is quickly come out.

Creating two lenses, and then connecting them in a formation to form a whole, is far more elaborate and easier to operate than Lin Hu's original idea.

One side is inside the venue and the other side is outside the venue, so you can broadcast the scene inside the venue outside the venue.
