I'm doing bidirectional science popularization in American comics

Of course, both the Joker and Joseph are now very obedient to Depp.

Therefore, Depp also told the Joker to stop short of causing chaos and not to let Clark truly go insane.

The clown immediately agreed, "Don't worry, I'll only engage him in regular combat, and at most try out the new thing I just developed."

The battle between Clark, the Joker, and Harley Quinn was about to begin, but Clark vanished the moment the fight started.

Bruce felt a headache coming on. On the first day of sparring, he was punched by Clark and sent flying to the edge of the training field.

"Tsk tsk tsk, it looks like Joseph is in for a lot of trouble!" Bruce said with great interest. "But Clark, you better go easy on him. Joseph doesn't have the suit I made. If you use that kind of force, you might just turn Joseph into dust with one punch."

But the next second, something happened that completely surprised Bruce!

Clark, who had disappeared, reappeared without warning next to Joseph and Harley, who was leaning against him with a baseball bat. He was kneeling on the ground in pain, clutching his stomach and bending over.

At this moment, Clark's expression was ferocious and twisted, his face was deathly pale, and occasionally a green light would flash from the blood vessels under his skin.

"Cough...cough...cough..."

Clark lay curled up on the ground, like a boiled deep-sea shrimp.

Clark was twitching, his eyes were rolling back, and white foam was coming out of his mouth.

“What did you do?!” Bruce asked.

The Joker glanced back and said, "If you can't even tell the difference, you can forget about being Batman."

“That’s right!” Harley picked up a baseball bat and walked over to Clark, saying, “I could be Batman too!”

Harley raised the stick high and slammed it down hard on Clark's head, making a loud noise.

Upon seeing this, Bruce sneered, "How could a mere ordinary wooden baseball bat possibly cause any harm to Clark?"

Bruce had no doubt that the moment the baseball bat struck Clark's head, it would be shattered into countless pieces by Clark's ridiculously strong body!

But the next second, when the baseball bat landed on Clark's head...

Bang!

The image of the baseball bat shattering in Bruce's imagination did not appear.

On the contrary, Clark, who was hit squarely on the head with the stick, was knocked unconscious.

Furthermore, a large bump quickly grew on the spot where Clark was hit on the head with the baseball bat.

WTF?

Bruce looked completely bewildered. "What the hell is that baseball bat made of?"

However, as Harley walked back to the Joker, Bruce immediately realized the real reason why Clark was defeated!

"You... use that green stone?"

Bruce asked.

"That's right!"

The Joker snapped his fingers, and a bright green playing card suddenly appeared in his hand. He said, "As expected of Batman, you guessed it right away. I did use those green stones. I ground them into an extremely fine powder and then sprinkled them around me."

Upon hearing this, Bruce said, "So, no matter how fast Clark, being a Kryptonian, is, when he gets to your side, he will be affected by those Kryptonite powders, lose his power, and even... suffer unbearable pain!"

"That's right, I'm a fucking genius!"

The clown took out a fan from his pocket and started sucking in the surrounding air.

Soon, the kryptonite powder floating in the surrounding air was sucked away by the exhaust fan, and Clark slowly stood up.

At the same time, the large fleshy lump on the back of Clark's head also began to recover rapidly.

The clown removed the storage pouch from behind the exhaust fan and carefully poured the green powder that had gathered inside into a small, transparent bottle.

"What...just happened?" Clark asked, puzzled.

The clown waved a small bottle filled with fine green crystals in front of Clark and said, "It's because you inhaled this stuff!"

"This is......"

Clark looked closely and immediately recognized it as the green ore that was commonly found in the town and would leave one feeling weak.

It's also what Johnny Depp was referring to as... Kryptonite.

“This…this doesn’t count, let’s try again!” Clark said.

However, the Joker had no intention of fighting. He glanced at Clark and said, "There's no need to continue. I've accomplished my goal."

The clown tossed the small vial containing kryptonite powder into the air and caught it, saying, "I have proven that this stuff works wonders for you and your people, and that is enough."

The Joker put his arm around Harry and strode out of the training room, saying to Depp, "We're going back to the asylum, Mr. Depp."

Goodbye, Joseph.

"Goodbye, Mr. Depp," Halle said, turning back. "Goodbye, Superman!"

The Joker and Harley left without hesitation, leaving Clark standing there completely bewildered.

"What... what is this?" Clark was a little confused. "Is today's lesson... over already?"

Bruce smiled but didn't say anything. He immediately left the training room and headed straight for the place where kryptonite was stored and studied.

Depp walked over to Clark and said, "Don't be sad, Clark. You just experienced what the other teachers did a few days ago."

“Oh? But I didn’t teach Mr. Joseph and Miss Harley anything.”

Clark said, puzzled.

“No, Clark, you didn’t experience being a teacher, but rather…” Depp said, suppressing a laugh, “You experienced being a tool!”

Clark: ? ? ? ? ?

Regardless, the Gotham Justice League's training of Clark has officially ended tonight.

Clark has unknowingly become a completely different being from any of the previous Supermen!

Somewhere between the Moon and Earth, space flickered and distorted, and one after another, interstellar warships appeared in this starry sky.

Chapter 346 The Battle of Metropolis (Part Two)

Is that Earth?

Zod stood in the spaceship's control room, looking at the colorful planet with its predominantly blue color in the distance, and exclaimed, "What a beautiful planet."

The Kryptonian spaceship possesses extremely advanced technology; once its stealth mode is activated, it is completely undetectable by current Earth technology.

Just then, Zod's female adjutant, Fiora, pointed to the other side of the Earth and exclaimed in surprise, "General, look! The sun here is yellow!"

Zod turned his head to look at the yellow sun, and then said, "I remember there seems to be a part about the yellow sun in the records of Krypton."

Fiora nodded and said, "Yes! The earliest records of the yellow sun are from hundreds of thousands of years ago, when Krypton was in the midst of a period of rapid interstellar colonization, and... at that time, the Kryptonians did not rely on the Codex to reproduce."

Zod's wife, Usa, came to Zod's side with her child in her arms, and pointed in the air with her finger, finding the record of the yellow sun.

These documents are quite old, suggesting that Krypton hasn't been in contact with the yellow sun for hundreds of thousands of years.

Hundreds of thousands of years ago, Krypton's interstellar colonization fleets expanded outwards.

At that time, Krypton was in the midst of a colonization frenzy.

Until the first colonial fleet encountered a yellow sun they had never seen before.

Initially, the Kryptonian warriors wore combat suits that could shield them from all external radiation.

At that time, they still did not understand what kind of effect the yellow sun would have on them.

It wasn't until a warrior was fighting against some powerful native creatures in that star system with a yellow sun, and his armor was completely destroyed by the creatures' desperate attacks, that the warrior was finally bathed in the light of the yellow sun.

Initially, the soldier suffered terribly due to the different atmospheric environment and sunlight.

Blood streamed from his eyes, ears, nose, and mouth, and the pain throughout his body caused this battle-hardened warrior to kneel on the ground.

But his body quickly adapted to the environment.

And...his body underwent extremely rapid changes under the yellow sun's rays.

The Kryptonian warrior's body eagerly absorbed the energy from the yellow sun.

At the same time, he also gained unprecedented power.

This power could easily surpass Krypton's hundreds of thousands of years of technological accumulation.

This warrior became the first Kryptonian to possess superhuman powers.

After spending two whole months thoroughly familiarizing himself with his power, he began attacking his own kind!

Krypton's suits and weapons are no match for Superman, who is completely familiar with his power and uses it without holding back!

After killing nearly half of his Kryptonian brethren, the rest finally succumbed to his tyranny.

Soon, the Kryptonian warrior demanded that the fleet sever ties with Kryptonian headquarters and establish himself as king on a new planet.

This concludes the initial record of Krypton's history regarding this fleet.

Two years later, Krypton finally sent a more powerful fleet to the star system to clear out the rebels who had cut off contact with their home planet.

But when the Kryptonian fleet arrived again, they found that the Kryptonians who had defected from the home planet had all been killed or wounded.

Even this planet has become a desolate, uninhabited place, with no trace of life to be found.

After the fleet brought the news back to Krypton's home planet, it was analyzed by Kryptonian scholars.

It is likely that someone later discovered the alteration of the Kryptonians' power by the yellow sun, which led to a full-scale war.

The war between Kryptonians who have gained superhuman powers will undoubtedly cause irreparable damage to their planets, and may even destroy a planet altogether.

In the centuries that followed, several Kryptonian colony fleets that had been baptized by the yellow sun betrayed their home planet after gaining power.

Therefore, Krypton quickly abandoned its interstellar colonization policy and began developing a "secret code" that could selectively cultivate genes and ensure that all those born would never betray Krypton.

“The yellow sun seems to enhance our strength,” Fiora said. “Perhaps we can try basking in its sunlight, just like our ancestors did.”

Upon hearing this, Usa immediately said, "I think we can let those unimportant guys go wade through the water first."

Upon hearing this, Zod shook his head and said, "No, I'll give it a try. They are all my people, the last remaining sparks of Krypton."

As he spoke, Zod walked toward the control room door and said, "Fiora, prepare my battle suit and the small spaceship for exiting the capsule."
