I'm doing bidirectional science popularization in American comics

The dense, layered clouds grew increasingly dark, resembling a void capable of swallowing everything in the world.

After the last dark cloud merged in, the thunder within them could no longer be suppressed.

With a deafening roar, thousands of thick purple lightning bolts, each as thick as a bucket, intertwined and coalesced into a super lightning pillar resembling a giant dragon, surging towards the wall of fire created by the Ancient One.

The purple lightning dragon plunged into the wall of fire, emitting a piercing thunderous roar, like the dying howl of a dragon.

The flames on the part of the fire wall that was attacked by the purple lightning dragon began to surge continuously.

Compared to the evaporating wave spikes, the Thunder Dragon's attack seems to be more effective.

"There's hope!"

Seeing a glimmer of hope, Depp excitedly increased the power he channeled into the Thunder Dragon.

However, when the final lightning dragon plunged into the wall of fire, Depp's newly ignited hope was instantly shattered, replaced by waves of despair.

Although the purple lightning dragon I just created had an effect, successfully weakening most of the fire wall, it still hadn't completely broken through that last layer.

If heat rays are used, Depp is confident that he can easily break through the fire wall.

But the training now focuses on the ability to control the ocean and the weather, something Depp cannot do.

"What should I do...?"

Depp said somewhat helplessly.

The Ancient One's voice immediately came: "Your training in water control has already succeeded with the ten thousand spikes of the waves just now. As for breaking through the current wall of fire... have you forgotten what I just said? The key is the combination of abilities."

“Teacher, how do I combine these abilities?” Depp asked.

Upon hearing this, Gu Yi's voice immediately became stern: "You need to think about it yourself. These are your abilities, not mine. Only you know how to combine them to become stronger."

Having received a response from the Ancient One, Depp had a sudden realization.

However, it wasn't about how to combine his own abilities, but rather that he suddenly realized that after a series of setbacks, he seemed to have started to rely on his teacher.

"I understand, teacher."

Depp thought to himself, in any case, relying on others is not a good thing!

Suddenly, Depp's eyes sharpened.

He looked at the spot where the fire wall had just been struck by lightning, a smile playing on his lips.

“I understand,” Depp said. “Decompose, ocean!”

Chapter 305 Instant Explosion

Somewhere on a planet covered by a vast ocean, thick, dark clouds in the sky resemble a predatory beast, suffocating all who behold them.

Slightly corrosive acid rain falls like a curtain across the sea, creating a myriad of connections between the sea and the sky.

Between the dark clouds and the sea, a wall of fire, with no blind spots, floats in mid-air.

The flames swayed back and forth amidst the gale and torrential rain, but their foundation remained as unaffected as a crimson Buddha.

Somewhere above the wall of flames, several fireballs, as if exploding, flashed with a crimson light before disappearing in an instant as the rain washed them away.

The sound of the fireball exploding was masked by the torrential rain and was almost impossible to hear.

But Depp immediately noticed this scene.

Depp stood on the waves, and after seeing the fireball created by the explosion, his mind immediately began to ponder.

Those explosions did not appear to be intentional on the part of the Ancient One, nor were they an inherent effect of the wall of fire.

These explosions just happened!

Furthermore, it only appears in areas attacked by the Purple Lightning Dragon, which is no coincidence!

Then, looking at the area above the wall of fire where explosions were still occurring, Depp gradually realized what was going on.

That's why Depp just shouted out:

"Decompose, ocean!"

Depp had a broad smile on his face, and his deep, captivating eyes were full of confidence.

Depp raised Neptune's Trident high, a flash of purple lightning appearing in his eyes.

At sea level, gale-force winds accompanied the vast ocean, and tens of thousands of waterspouts, each as thick as a well, burst from the surface at the same time.

Then, these water spouts that had burst out of the sea converged behind Depp.

Before long, an enormous blue-green sea dragon materialized behind Depp.

The sea dragon, reaching tens of thousands of meters in height, exudes an extremely terrifying aura as it churns up the seawater to form its dragon-like form.

Above the sky, patches of dark clouds once again converged towards the center.

Thick, ink-like clouds spun slowly, like a dark vortex in the sky.

At the center of this dark vortex, purple lightning flashed incessantly, as if something extremely terrifying was about to break through the restrictions and blockade of the dark clouds and descend upon the world.

Rumble!

Rumble!

A thunderous roar erupted, and blinding flashes of lightning seemed to coat the dark clouds with a purple cloak.

Finally, the dark clouds could no longer withstand the pressure of the thunder.

Tens of thousands of thick, purple lightning bolts surged forth from the dark clouds, heading straight for the wall of fire.

In mid-air, these tens of thousands of lightning pillars converged again, intertwined and merged, forming the same purple lightning dragon as before.

Then, Depp lightly waved Neptune's Trident, and the sea dragon behind him also moved.

The sea dragon, tens of thousands of meters tall, charged straight towards the wall of fire beneath it, following the direction of Neptune's trident.

"The same old trick or something new?" In the center of the wall of fire, the Ancient One, holding an orange juice, muttered to herself with a contented expression, "I hope you can give me some new surprises, Depp."

Outside the wall of fire, the Sea Dragon and the Thunder Dragon had already joined together, but Depp did not let the two dragons merge into one. Instead, they entangled with each other and crashed into the wall of fire.

Crackling sounds!

呲呲呲!

The thunder of the Thunder Dragon intertwined and merged with the sound of the Sea Dragon being evaporated.

Surprisingly, this time the sea dragon did not produce a large amount of steam after evaporation.

Soon, under the attacks of the Sea Dragon and Thunder Dragon, the fire wall began to weaken layer by layer!

Upon seeing this, Gu Yi smiled slightly.

"Although you have mastered the power to use both the sea and lightning, it is still not enough, my disciple."

Hearing what the Ancient One said, Depp's smile deepened.

Soon, the offensive of the Thunder Dragon and the Sea Dragon came to an end.

However, some of the firewalls created by the Ancient One have not yet been breached.

Is it going to be another failure?

Depp stood on the wave, making no further move, as if he had given up the attack.

But the smile on his face made Gu Yi suspicious.

Because she knew that Depp's smile wasn't a bitter one after a setback, but rather the smile of a victor.

When the Thunder Dragon and Sea Dragon outside the wall of fire finally exhausted all their strength, they completely dissipated.

Gu Yi bit the straw and took a leisurely sip of orange juice.

Then, Gu Yi's expression hardened, and a sudden change occurred.

Why did the flames suddenly become uncontrollable?

The Ancient One was puzzled. The next second, a deafening explosion accompanied by completely out-of-control flames caused the magical shield around her to flicker incessantly.

boom!

The massive explosion resembled a nuclear bomb, with a mushroom cloud connecting heaven and earth appearing simultaneously amidst flames and shockwaves.

The extreme heat generated by the flames and explosion instantly evaporated the surrounding seawater.

The shockwave pushed the remaining seawater in all directions, and the enormous tsunami surged outwards in all directions.

Even the layers of dark clouds in the sky were blown away by the shockwave from the explosion.

Depp stood on the distant waves, squinting at his masterpiece, his heart filled with joy.

"I knew I was right!"

The explosion, the intense heat, and the shockwave made the Ancient One realize that the wall of fire she had created had been broken!

"How is this going?"

The Ancient One stood at the very center of the explosion, recalling Depp's actions just now.

Scenes flashed through Gu Yi's mind, and finally she shook her head and laughed.

"This kid is really outrageous."

After a while, the aftershocks of the explosion finally subsided.

On the sea surface, there was a huge vacuum zone with a diameter of tens of thousands of meters, which made Depp himself feel terrified.

Soon, boiling seawater poured in, filling the vacuum zone once again.

Depp sprinted forward, only to find that the wall of fire had vanished, and the Ancient One stood with her hands behind her back on the sea, waiting for Depp.

"Did I... pass this training?"

Depp asked with great interest.

Upon seeing this, Gu Yi removed the protective shield around himself.

When Depp saw the Ancient One's perfectly intact robe, he felt a wave of dizziness and nearly fell into the sea.

"Are you kidding me? This still doesn't work..."

Before Depp could finish speaking, the Ancient One tore off a corner of her robe and casually threw it into the sea.
