The Comprehensive Evolution of American Comics.

Chapter 1192 The Time-Space Transporter is Completed
“I won’t deny it.” Yang Le didn’t care about Ban 23’s ‘threat’; instead, he reminded the latter.

"You didn't know that this door is actually one-way, did you?"

Class 23 was stunned and hurriedly asked, "What do you mean?"

“It means exactly what it says,” Yang Le explained. “If you use a warlock in this universe, you can only summon one portal to Daming City. If you want to summon a portal to other universes, you can only do it again in Daming City.”

"What is this?!" Class 23 yelled, clutching his head. "How can there be something so troublesome and inconvenient!"

"If the Supreme Damasa agrees to Damian's strategy, then we should already be fugitives in Damasa City."

Yang Le stroked his chin and teased, "We might already be on the wanted list. The moment you land, you could be caught like a wanted criminal in real life."

Seeing the headache-ridden Class 23, Yang Le was amused, but before he could enjoy the spectacle for long, Splinter interrupted him.

"I just overheard you talking to Donatello, Yang. Have they finished that time-space teleportation machine? Can Ben use it to go home too?"

Upon hearing Splinter's words, Class 23 immediately lowered his hands from scratching his head and looked at Yang Le, who, seeing this, stopped trying to hide his thoughts.

“That’s certainly possible.” Yang Le nodded. “I didn’t tell you earlier just to teach you a lesson. Remember to always be fully prepared before doing anything, and don’t venture into unknown territory lightly.”

"Okay, I understand." Class 23 was completely fooled by Yang Le and actually forgot about how the latter had just watched him make a fool of himself. He obediently agreed.

"Alright, let's not talk about that anymore. Let's go back to the dungeon and check on Donatello and the others' work."

“You guys go back first.” Damian picked up his bundle. “I need to get control of the Bigfoot Ninja first, then I’ll come back to meet you later.”

After saying that, Damian turned around and wanted to head to the Bigfoot ninja base, but was stopped by Class 23.

"Take me with you," Class 23 pleaded, clasping his hands together. "I've never seen a real ninja organization before, please take me with you."

“Sure.” Damian didn’t refuse, but tossed the backpack to Class 23.
"In that case, you can continue carrying this burden."

...

After bidding a temporary farewell to Damian and his companion, Yang Le and his group returned to the underground city, where they found several guards waiting for them.

"Welcome back, sirs."

Because Yang Le and his companions had previously helped the Atem people, the guards treated them with great respect, addressing them as "sir" or "master" upon meeting them.

If Yang Le and the others hadn't refused, these guards would probably have had to bow to them upon first meeting. Even Splinter wouldn't have been able to stand it, let alone Yang Le.

"Donatello and his team succeeded?"

"Yes, Lord Donatello and his men completed the new time-space teleporter a day ago," the guard replied respectfully.

"They are currently in the center of the underground city. Please get in the car, and I will take you there."

The vehicle the guards were referring to was a new type of transportation developed by the Artemians after they arrived in the underground city, based on the floating vehicles left behind by the underground people.

In addition to the well-known energy sources, the energy used also includes underground crystals that can be found everywhere in the underground city. After all, such resources are everywhere, so wouldn't it be a waste not to make use of them?
The new floating vehicle was very fast, and in just a few minutes it brought Yang Le and the others to the center of the underground city. In fact, Yang Le had seen a huge instrument from a long distance away from their destination.

It's basically an enlarged version of Artem's time machine, with a transparent semi-circular dome added on top, making it look like a crystal ball from a gift shop from a distance.

"Yang Le!"

Before he even got out of the car, Michelangelo greeted him with a lick of his lips. Judging from his expression, he must have heard from Donatello about him buying pizza. "Here you go," Yang Le said without hesitation, handing the pizza box he was carrying to Michelangelo.

"There are ten boxes in total. I paid extra to buy all the ones that are about to come out of the oven. That should be enough for you, right?"

"Enough, enough!" Michelangelo's mouth was practically watering. "I've been waiting for this. If I'd known you were bringing back pizza, I wouldn't have eaten breakfast."

Michelangelo opened the top pizza box, his mouth watering at the sight of the colorful cheese flatbread. Just as he was about to take a bite, another, faster hand snatched it away.

Hey! That one was the one I liked first!

Despite Michelangelo's accusations, Raphael, who had stolen Michelangelo's love, was unconcerned, took a big bite of pizza, and laughed as he spoke.

"Only those who seize the initiative will win the competition."

Michelangelo was furious, but in the end he could only reconcile with himself and take another piece, which he then devoured with great relish.

"Hey you two, move aside."

Donatello squeezed between the two brothers and put his arm around Yang Le's shoulder with a smile.

"You're finally back, Yang Le. I'm sure it won't be long before you can go home."

“Of course I believe in you, Donatello.” Yang Le patted Donatello on the shoulder. “There’s nothing in this world that you can’t invent.”

"Although I know you're just flattering me, I still enjoy hearing it."

Donatello's smile widened. He knew that Yang Le was actually half a colleague of his, both being inventors. There was nothing more gratifying than hearing praise from a peer he admired.

"Why don't you give it a try first? With this, you can freely travel between our universe and yours."

"Don't be so hasty, Donatello," Yang Le reassured the excited Donatello. "Let's eat first. We still need to wait for Damian to come back. Oh, and when he gets back, I'll introduce you to a new friend."

"A new friend? Is he also an inventor?"

"No, he's not an inventor at all; he's more like a bit of a simpleton."

...

"Ah!"

Class 23 rubbed his nose: "Someone must be talking badly about me."

"It must be those commoners from the Great City." Damian silently moved aside to avoid being sprayed with a sneeze.

"Maybe." Class 23 sniffed. "Hopefully I'm not catching a cold. Although bad words aren't very pleasant to hear, I can't hear them anyway, so bad words are better."

"By the way, how much longer until we get to the rooftop?"

“Almost there.” Damian watched the numbers jump around. “Remember, don’t say anything rash later. Wait until I become their leader before you speak…”

"Okay, okay." Class 23 waved his hand. "I remember to transform and help you escape when things get bad, Ninja Master."
