It’s still the familiar mage tower.

It’s still the familiar dilapidated door.

And the completely unfamiliar brown bear lying on the table...

"Teacher, what's going on with you?"

Seeing Rex lying on the table with a pale face and looking like he was about to die, Fang Zheng couldn't help but be shocked. He came to the White Tower of Heaven for the magic exchange meeting and came to see his mentor. What happened? A sudden illness? Should he call 911? Oh... It seems that there is no 911 in this world...

"Oh, you're here..."

Hearing Fang Zheng's voice, Rex weakly opened his eyes, looked at him, and then closed his eyes again.

"Uh... I came to see you, mentor. Are you... sick?"

Fang Zheng looked at the burly Rex and couldn't understand what was happening to the dying man in front of him.

"It's all your fault."

"I?"

Fang Zheng felt that this was really a case of "the pot comes from the sky while you are sitting at home". What happened to me? I stayed in Tiandao Palace for a while and did not go out of the gate. How could it be blamed on me again?

"You gave Lady Colette a thing called... an electron microscope, right?"

"yes……"

It's just a biological electron microscope, and it's not worth much. Colette wanted it, so Fang Zheng gave it to her. What's the problem with that?

"Why……"

Rex sighed again.

"Well, you know what's in our blood."

"Red blood cells, white blood cells, platelets?"

Fang Zheng thought about it carefully and then gave an answer. When did his mentor become interested in this thing?

"Why……"

Hearing Fang Zheng's answer, Rex sighed again and looked depressed.

"Don't you feel uncomfortable?"

"……?"

Fang Zheng said that he had no idea what Rex was talking about, but then, this burly, strong and stocky instructor of the prophecy department spoke up.

"Just think about it, there are thousands of round red balls rolling around in your body. Don't you feel uncomfortable? Oh my God... What hatred does Lady Colette have against me that makes me want to know this... I feel itchy all over my body now, as if those round balls are rolling around in my blood vessels, and the platelets, they look like demons... Ah, I can even feel their tentacles wriggling densely in my body..."

"Uh, mentor, you better stop talking..."

It would have been fine if Rex hadn't said anything, but as soon as he said it, Fang Zheng felt itchy.

"In fact, you can't feel them at all. You should know how small those cells are. We can't even see them with our naked eyes..."

"But it is the blood they form..."

“That’s right…”

Looking at Rex in front of him, Fang Zheng didn't know what to say for a moment. He didn't expect that his mentor, who looked like he could kill a bear with one punch, would have such a weakness - this should be considered as trypophobia.

Although he thought his mentor's weakness was a little funny, Fang Zheng didn't want to dwell on it, so he decisively changed the subject.

"I came to the White Tower this time because of the Crystal Tower... I heard that you want me to build a Crystal Tower here?"

"Oh, yes, that's right, that's what happened."

Hearing this, Rex straightened up and patted his face, obviously trying to put the uncomfortable topic behind him. Then he took out a rectangular black object from his pocket - it was the Yali smartphone produced by Fangzheng Tiandao Palace.

"We have studied the technology here, and it is indeed very interesting. It can find a way to unify magic spells at different levels. This alone is enough to qualify you to participate in this magic exchange meeting. But... you said this thing can communicate? How do you do it?"

"It is indeed necessary to build a crystal tower."

Fang Zheng immediately started to explain.

"To put it simply, this mobile phone is a terminal, and data transmission needs to be completed through interaction with the Crystal Tower..."

"So, how big is this range?"

"Basically one crystal tower can cover half a block."

"Let's go and give it a try!"

Hearing Fang Zheng's answer, Rex immediately stood up and patted his face.

When Fang Zheng followed Rex to an open space outside the White Tower, Colette and several other chiefs were already waiting there. It was obvious that they were all very interested in this epoch-making invention - provided that this thing called a mobile phone was really as Fang Zheng described.

"Here?"

"Yes, let's do it."

Rex glanced at Colette, obviously not wanting to waste more time on a certain topic with her, so he quickly waved his hand and signaled Fang Zheng to start. Fang Zheng immediately took out a Tanji from his personal space and placed it on the ground.

"What's this?"

The Chief of the Enchanting Department looked at the round-headed little fellow in front of him with curiosity, not hiding his interest at all.

"This is called Tanji, a kind of...construct."

Fang Zheng briefly introduced the chiefs, and then he snapped his fingers. Soon, everyone saw a flash of lightning shooting out from the center of the Tanji and hitting the air. Then, the shadow of a crystal tower slowly appeared in the empty air.

"Is this... some kind of teleportation technology?"

The chief of the spell department on the other side closed his eyes, and then he clearly felt some kind of spatial fluctuation.

"That's right."

Fang Zheng did not hide anything.

"This is a technology unique to Tiandao Palace. We will manufacture the required items in Tiandao Palace, and then use Tanji to activate the transmission and place them at the designated location."

“Interesting idea.”

Hearing this, the chief of the spellcasting department's eyes lit up and he nodded repeatedly. Then he looked at the other mages around him.

"I think we in the Magic Kingdom should also try similar technology. It is very suitable for fighting in the wilderness."

"Indeed, compared to transporting supplies, local teleportation is a better idea. Moreover, since we are teleporting inanimate objects, we don't have to worry about the impact of space dynamics..."

There are no fools among mages, not to mention that the mages of the White Tower are the top elites in the Magic Kingdom. Learning from one example and applying it to other situations is something they are very good at.

As everyone was talking, there was a soft "swish" sound, and then a crystal tower appeared out of thin air, quietly suspended in the air. It emitted a faint glow and looked quite beautiful.

"It seems that with this, we can even save the street lights."

Rex looked at the glowing crystal tower in front of him and couldn't help but smile and speak, but at this moment, the chief of the Transfiguration Department couldn't help but raise his eyebrows.

"Wait, do you think something is wrong?"

"Something's wrong?"

After hearing the words of the Chief of the Transfiguration Department, everyone focused their attention. Then after a moment, Rex's expression changed slightly.

"It seems like the magic power has become more stable?!"

"Yes, I felt it too!!"

At this moment, several other mages also nodded. You know, stable magic power is very important to them. Mages need to rely on external magic power to cast spells. If the magic power is too violent, then the magic is likely to go wrong or even be countered. On the contrary, if the magic power is "smooth as silk", then they will be able to release spells more smoothly and comfortably!

"The Crystal Tower can suppress chaos and create order. It can indeed stabilize the fluctuations of magic power to a certain extent."

Compared to the extremely surprised crowd, Fang Zheng seemed very calm. After all, he already knew about the effect of the crystal tower. Otherwise, he wouldn't dare to take it out like that, right?

“Is there such an effect?”

Hearing this, the eyes of all the mages present almost turned red. This time, the way they looked at the crystal tower finally changed. Apart from other things, the crystal tower's ability to stabilize the fluctuation of magic power is priceless! !

"Mr. Fang Zheng, are you planning to sell this crystal tower as well? Can I ask the price?"

The chief of the Shaping Department hurriedly asked, but this time, he did not treat Fang Zheng as a wizard of the White Pagoda, but as the leader of the Tiandao Palace.

"Of course, the mobile phone needs to be paired with a crystal tower to be effective. If you want to communicate remotely, it is necessary to set up a crystal tower. As for the price..."

Fang Zheng thought about it for a moment and decided to give them a fair price, about a hundred times the cost.

"Five hundred thousand platinum coins, maybe."
