Invincible! This person has lived for a billion years-Chapter 800 Fireball Spell？!

The five-colored mutant python could now understand what William was saying.

Filet mignon?

How could these damned bipeds even compare it to something like a filet mignon?

After all, it was a dominant force on Mount Olympus, its massive body and venomous fangs allowing it to defeat most other mutated creatures. On Mount Olympus, few could suppress it, let alone these frail bipeds.

Frail...

The five-colored mutant python tried to bite down hard, only to find that the bipedal creature in its mouth was incredibly strong and could withstand the immense biting pressure. No matter how hard the python tried, the creature didn't budge.

"Don't spray your venom!" William said, and just like that, the five-colored mutant python's venom glands were completely blocked, unable to release any venom. It felt as if its glands were forcibly clamped shut, an incredibly uncomfortable sensation.

The five-colored mutant python realized something was very wrong.

This bipedal creature was not normal!

If it were a normal biped, its bite would have turned them into a lump of flesh and blood.

It was confident in its strength.

But this creature... just with a single sentence, it made it impossible for the python to even spray its venom. Wasn't that terrifying?

William completely ignored the five-colored mutant python's discomfort and turned to Silas, "Next, I'll teach you the art of controlling fire."

Saying this, he released his grip, and the five-colored mutant python found itself unable to bite down.

"Move back a bit! Bring your tail to the front." William felt that since they had met, it must be fate. This five-colored mutant python was clearly fated to cross paths with him, so inviting it to a meal wasn't too much, right?

The five-colored mutant python didn't understand what was happening to it. Was it bewitched?

Following the command of the biped in front of it, it actually moved back and brought its tail forward.

Silas was puzzled by the situation...

What was wrong with this giant snake?

Why was it so obedient to Mr. Johnson's words?

Could it be that this mutated giant python was Mr. Johnson's pet?

The five-colored mutant python positioned itself about 10 feet away from William, its tail in front, and asked somewhat fearfully, "What are you going to do to me?"

As a dominant creature, it now felt like a helpless girl surrounded by thugs in a corner, pitifully looking at William.

William raised an eyebrow, "I don't really plan to do much, just that my new student here wants to practice some skills on you."

Practice skills?

The five-colored mutant python was filled with confusion,it clearly didn't understand what William meant.

"I'll start by teaching you the simplest fire magic, the Fireball Spell." William thought for a moment and then instructed Silas, "Follow my lead, start by learning the gesture to release the magic."

William slowly demonstrated a hand gesture.

Silas followed and learned slowly.

However, just as William made a gesture, the sky turned blood red, and terrifying flames gathered wildly, enveloping the entire earth, causing glaciers to start melting.

Mutated creatures around the globe began to stir restlessly, their instincts telling them that death was approaching.s were even more panicked.

Countless people trembled as they looked up at the sky.

"What on earth is happening?"

"Is another disaster coming, or has some malevolent deity arrived?"

"It looks like the earth is going to be destroyed, it's all over! Everything is finished!"

...

Everyone felt uneasy, and many children were scared into tears, while some chose this moment to rush into the Doors of Evolution.

Perhaps inside the Doors of Evolution, there might still be a way to survive,the flames in the sky were just too frightening.

"Hmm?!" William also noticed the commotion in the sky.

He had never used magic so formally before,now that he had properly made a magical gesture, if the flames from the sky fell, it could really destroy the entire planet.

It seemed he should avoid using magic carelessly in the future.

He blew a breath towards the sky, and the terrifying flames immediately dissipated. Then he said to Silas, "Next, feel the energy around your body transforming, convert the surrounding energy into flames, then aim at the tail of this snake and shout 'Fireball Spell.'"

The Cosmic Entity Dolly, the manager of the thirteen universes, had already left the thirteen universes, but the laws originally established in the thirteen universes hadn't changed much. Teaching Silas magic was just a slight modification of the spellcasting method for William, and it wasn't a difficult task for him.

Previously, formal magic required beginners to recite a long spell,

For instance, to release magic, not only did beginners need to mutter spells, but they also needed to prepare some herbs, gems, special rune papers, and gods even had to draw out magic circles in advance.

Then, specific gestures were needed to guide and control the magical energy.

All of this seemed too cumbersome to William.

Why not keep it simple?

Silas, naturally gifted with a Divine Constitution, learned quickly, and a ball of red fire lightly floated towards the tail of the five-colored mutant python.

"Puff!"

The fire landed on the five-colored mutant python, sparking a small flame that extinguished instantly.

The five-colored mutant python, after all, was a powerful beast. Silas's casual gesture aiming to roast it for a meal was clearly unrealistic.

"Mr. Johnson... I..." Silas felt he had performed very poorly. He had managed to convert the surrounding energy as Mr. Johnson said, but the conversion wasn't very effective.

"Hmm, not bad, just keep practicing," William didn't dare expect Silas to burn down the entire forest on his first try.

Silas clenched his fists, excitedly looking at William. This was the first time he had ever been praised.

"Go on! Don't be afraid of it!" William pointed at the five-colored mutant python not far away.

The five-colored mutant python was almost paralyzed with fear.

Others might not know, but it saw clearly that this biped had merely made a casual gesture, and the whole world was on the brink of destruction.

And that intense oppressive feeling was too terrifying!

It had actually thought about eating William just a moment ago.

Now, hearing William's words, it didn't dare move an inch.

Silas repeatedly used the Fireball Spell, becoming more efficient at converting the surrounding energy, and the flames grew larger and larger.

But still, the attacks left not even a mark on the five-colored mutant python.

Clearly, such attacks couldn't harm the five-colored mutant python.

As the sun set, it was time for dinner. William waved his hand, and a table appeared in front of them, along with two chairs, two sets of dinnerware, and even a set of cooking utensils.

"Are you hungry?" William looked at the sweaty Silas and asked softly.

Silas nodded cautiously. After practicing the Fireball Spell all afternoon, it was impossible not to be hungry.

William smiled, "Then sit there, dinner will be ready soon."

Silas obediently took his seat, unsure of what Mr. Johnson was going to do.

William casually picked up a Chef's Knife he had bought at the supermarket earlier, his gaze falling on the five-colored mutant python.

The five-colored mutant python, making eye contact with William, felt as if a huge "DANGER" sign was etched on its forehead.
