......

A long time ago, a group of alien visitors set out from a planet to Blue Star.

It is said that it is a planet with a brilliant culture that is rare in the world.

They were full of longing for this journey.

They heard that a great philosopher of the Blue Star era would greet him where they landed and would take them to see everything on the Blue Star.

They saw fresh and tender green vegetables, lush forests and trunks of tree trunks, broad pastures and herds of cows, and people of different skin colors in various countries around the world.

Alien visitors like creatures full of spirituality, trees with green heads, animals that lower their heads to eat grass. Although philosophers say they have no time to think or speak, alien visitors don't think that way. He can understand the sound of the wind blowing through the leaves and understand the perseverance of grass growing from the rocks. He loves every creature on the Blue Star.

But he didn't like the bustling men and women in the city. He didn't know why alien visitors thought they were unfriendly, and the reason why they couldn't say was that humans were weird.

A long time later, hundreds of years later, alien visitors visited Blue Star again. The philosopher had already left the world. They were greeted by a young tour guide who took alien visitors to the places they had visited with philosophers again.

What he saw was unexpected. The trees were no longer green, the aurora was no longer dazzling, and there were countless white pollutions in the grassland. The tour guide used his usual accent to explain to alien visitors, "Due to the imbalance of ecosystems, severe environmental deterioration, and shortage of natural resources, human beings have begun to escape, bringing property and useful poultry and livestock, and I don't know where Noah's Ark took them."

The alien visitors were silent. No wonder they thought humans were strange from the bottom of their hearts. It turned out that they always wanted to be above all things. In his impression, all creatures on the Blue Star lived in harmony, but this was not the Blue Star in his impression.

"A such a planet should not be wasted in the hands of the Blue Star people, do you think so?"

"Yes. It should not be wasted in the hands of the Blue Star people."

......

It was a strange aircraft.

It looks like a blue phone booth.

The Qiansui Emperor called her Tadis.

It seemed that in his eyes, Tadis had life.

This is also reflected in Taiyi of Eight God.

Along the way, there were several aliens sitting on this aircraft with them.

They had no sense of rejection of the Blue Star people, and even invited Yagami Taiyi to enjoy the food they carried together.

Xu Jiuqiansui did not refuse, and naturally Taiyi of Eight God did not.

The story just now was learned from them.

The story is very strange, as if it is talking about Blue Star, and as if it is not just talking about Blue Star.

So, in the end, the Eight God Taiyi was a little confused.

With doubts, they arrived at the terminal.

It was a field.

It's autumn.

The whole field is occupied by golden yellow.

They walked down Tadis, and Yagami Taiichi looked around and asked in confusion:

“Where is this?”

"Zhennan City many years ago."

Xu Lai told Yagami Taiichi:

"At that time, you were still very young... At that time, aliens had not occupied your Blue Star yet..."

He walked straight forward, following another companion of their trip.

A cat with black body.

It is called black charcoal.

Yagami Taiichi followed, subconsciously turned around, but found that the aircraft called Tadis had disappeared.

He approached Xu Lai and Hei Tan a few steps and heard that they were discussing Tadis.

The problem is black charcoal:

"Is she really Tadis? She is not pirated like my abilities, right?"

"It's true."

Xu Lai replied.

"Doctor Who's Tadis?"

Black charcoal is confirmed again.

"certainly."

Looking at Xu Lai's casual words, Hei Tan immediately said:

"I'm going, you actually know the Doctor???Aren't you the devil of the East? How could you know a time traveler who is wandering around Europe?"

"First of all, I am the devil of the East, right, but if you can't die and your soul can't be destroyed, the East is so big, and you will be able to spend a tour sooner or later. At that time, will you not go west?"

Xu Lai emphasized:

"In addition, the Doctor is not just wandering around Europe. He may appear in any time dimension. Don't be too envious of this."

Yagami Taiichi didn't understand why Kurotan was surprised.

He just probably knows it.

That Tadis, and the Doctor Who they mentioned, are quite not simple.

It is said that Tadis is a product of Time Lord's technology. With proper maintenance and driving, Tadis can reach any time and space point.

Tadis is larger inside than outside, and her chameleon system is able to blend it with its surroundings.

In the story about the doctor in Black Charcoal, the Tadis driven by the Doctor was originally an outdated model (Type 40), with not very stable performance, and was stolen by the Doctor. Once as a TT capsule, its chameleon system was damaged, which kept it in the shape of a police booth in London, England in the 1950s. The Tadis was from Gallifrey, when it was under maintenance, and suddenly lost control—the impact range reached the entire universe—and this kind of thing happened from time to time during the Doctor's trip.

Then Tadis operates very special.

Tadis's soul is connected to the Time Lord through the Key of Rassilon (this technology is also considered to be developed by Omega, and the time travel technology was originally developed by Omega), so non-Time Lords do not have the Key of Rassilon and cannot manipulate all the time travel technology similar to Tadis's Technology (otherwise they will fall into a time vortex and cannot return), unless they obtain the Key of Rassilon.

Secondly, Tadis's own self-awareness allows it to operate and drive to a certain extent, supplementing it with the control of the Time Lord. However, Tadis's function does not mean that it is a completely different time travel machine. It will also fall into a time vortex and be captured during operation. For example, in Time  and  the  Rani hit Tadis with a traction beam to rebirth the doctor, and Tadis is also on the verge of destruction due to the absorption of the magnetic arm.

Tadis's cab changes with each doctor.

......

Hearing Black Charcoal rumbling.

Yagami Taiichi can feel it very clearly:

"You should be a fan of Tadis and that doctor, right?"

"It's a huge fan."

Hei Tan said, if it weren't for being unable to hide his face, it might have pounced over and wanted Xu Lai to take him to meet his idol, Doctor Who.

But now...

Tadis is gone.

If she was as self-aware as Hei Tan said, she probably wouldn't come back during this period.

Because they have something to do here.

Tadis will obviously not be around again until things are done.

Then, Hei Tan looked depressed.

Sitting on the shoulders of Yagami Taiichi, following Xu Lai's footsteps, he passed through the field and found a road to the city.

“It looks so familiar here?”

Taiyi Yaji looked around:

"When I was in elementary school, my teacher took us here for an outing."

Xu Lai didn't say anything.

Instead, I was silently muttering something in my heart.

Not long after, a whistle sound came.

"really......"

Xu said these two words, which attracted the attention of Hei Tan.

He turned his head and looked at it, and was stunned: "Bus No. 39? I'm going, why do I have it everywhere?"

The car stopped in front of the two of them.

The driver is still Lao Wang.

When the exact same old Wang appeared in front of them.

Xu Lai was naturally nothing to be surprised.
