Royal Palace, World Park.

Ling Lanxin, Lingzhou and his brothers arrived and greeted Danni and others.

After the greetings, Danni smiled at Lingzhou and said, "Your Highness, we discussed it and thought about playing in Lanling for a few more days and returning to Europe in a week."

"oh?"

Ling Zhou was stunned. He thought Danny, Erin Bain and others would think of returning to Europe immediately. After all, so many disappointing things happened in China.

Especially Dora Mill, who has been depressed since returning from China.

He thought she would rush home.

This time he came here, he just wanted to say goodbye to them.

If possible, I will take them to the airport this afternoon.

"Your Highness Zhou, to be honest, Shennongjia and his party are a little..."

Prince Joey Elam shook his head regretfully at this time.

As he said that, he smiled and said, "Our Golden Alliance's first gathering can't leave in a sloppy manner! So we thought that in the next time, we will gather in Lanlingduo."

Ling Zhou glanced at everyone after hearing this.

He found that at this moment, everyone seemed to truly regard themselves as a member of the alliance.

Otherwise, they would propose to return to Europe at this time.

And at that time, this golden alliance probably no longer existed.

"Okay, welcome."

Ling Zhou clapped his hands and nodded with a smile.

Afterwards, they discussed activities in the next few days.

At noon, Ling Zhou asked someone to arrange lunch. Ling Zhou and his sister Ling Lanxin shared lunch with Prince Goode, Danny, Hess and others in the World Park.

After lunch, Ling Zhou and his sister Ling Lanxin left the World Park.

After leaving the World Park, Lingzhou returned to his yard to rest for a while.

I woke up and it was almost 3 pm.

...

3 pm.

Ling Lanxin also came to the courtyard.

Just as the siblings were having tea and chatting, Chen Yiru came over.

"Your Highness, the sound of the sound has arrived."

Chen Yiru said.

"Oh! Please come in."

Ling Zhou nodded, raised his head and smiled.

"yes."

Chen Yiru nodded.

After a while, a casual lingering sound came over.

Today she was wearing a white button T-shirt with a simple design, loose cropped pants on her lower body, and she was casually draped over her shoulders, wearing a pair of large-framed glasses. She was capable and had a hint of elegant temperament.

It makes people fascinate at first sight.

Today, she was carrying a box the same as last time.

"Yuyin has met His Highness the Prince and His Highness the Princess."

Yu Yin walked forward and asked politely.

"Miss Yu, please sit down."

Ling Zhou stood up and smiled.

Ling Lanxin also smiled gently at her.

"Thank you, Your Highness."

Yu Yin nodded with a smile, put the box aside, and sat on the sofa opposite Lingzhou.

Ling Zhou glanced at the box and was a little looking forward to it.

I don’t know what kind of surprise the lingering sound will bring this time.

Afterwards, Xiaolian brewed a pot of tea for them.

The tea brewed is naturally Dahongpao.

Dahongpao is the royal misuse of the royal family today and is also a drink for guests.

After drinking tea and chatting for a while, Ling Zhou asked expectantly: "Miss Yu, I wonder what achievements will be made during this period?"

Today is September 15th. He handed over his core technology to Yu Yin in early August. Now it has been a month and a half, and I don’t know if he has achieved any results.

I think there should be some. If there is no result, she will not come here.

Yu Yin smiled when she heard this.

She thought Ling Zhou would always be calm and not ask herself.

She had no other intentions, just looking at the prince who is much younger than her, sometimes a little cute, but very noble, she couldn't help but want to tease her.

Immediately, she put away her smile and said, "Your Highness, we have made a major breakthrough in the core technology of the 'a1 detection aircraft' because of the technology provided by your Highness."

As she said that, she opened the box beside her.

Lingzhou, Ling Lanxin and his brother looked over.

I saw a small plane of exquisite style lying in the box.

This small aircraft is smaller in size than the last time. It is only about 20 cm in length, and its width is about 10 cm in 1 with its wings. The overall color is sea blue, without a trace of variegated color.

"Your Highness, this 'mineral detection aircraft' is an evolutionary version of the 'a1 detection aircraft'. In terms of mineral detection, its various technologies have made great breakthroughs. This 'mineral detection aircraft' is 50 years ahead of the world in technology and can detect 8,000 meters deep underground. Moreover, its detection signals can penetrate all the rock layers of the formation and detect mineral resources hidden deep underground. In addition, it uses absolute waterproof technology and can work in the sea for two consecutive years. Regarding energy, it uses light energy charging, which can be used in the sea and at some point, to obtain energy supplements. Also, its appearance uses a color change technology. Once it enters the sea, it can be integrated with the sea. Even fish will not find its existence."

Yu Yin said confidently.

Ling Zhou exclaimed, and then felt that Yu Yin was not right.

"Ms. Yu, is this detection machine not limited to oil detection?"

Lingzhou asked.

The information he gave to Yu Yin seemed to be the name of the "micro-oil detector", but after Yu Yin's research and development, it seemed that it had changed a lot!

"Yes Your Highness."

Yu Yin smiled and said, "But the main function of this instrument is to detect petroleum, energy, mineral resources. It will have a much smaller effect on other mineral detection, such as gold mines. However, with technological breakthroughs, the effect will become greater and greater. The depth of the detection will become deeper and deeper. It is expected that the maximum depth can reach 100 million meters underground."

Ling Zhou nodded and looked at his sister beside him.

Ling Lanxin was already shocked by the lingering narration.

As far as she knows, the mineral detection technology in the world today can detect the depth of 4,000 meters deep in the ground. She doesn't know the details, but it will not exceed 5,000 meters anyway.

But this instrument can actually detect the depth of 8,000 meters underground, which is directly doubled!

8000 meters!

You should know that the mineral detectors on the market today can generally detect the depth of only a few hundred meters.

Moreover, 8,000 meters seems not to be the limit.

The limit can even reach 10,000 meters?

This surprised her.

And what surprised her even more was that this detector could actually detect automatically.

Judging from the lingering sound, it seems that by putting this "mineral detection aircraft" into the sea, it can automatically detect without anyone guarding it. It just needs to detect mineral resources and send back the signal.

This is really an epoch-making technology!

But is what Yu Yin said true?

Are there any exaggerated ingredients?
