Zone Zero: I'm invincible now that the heavenly fire has killed Nineveh!

Soon, the group set up a field on the spot in the training area.

Or perhaps it was simply a rope hung in the middle, without even defining the boundaries.

At this time, Su Chen also learned about the special tennis rules of the Sixth Anti-Air Division.

The ball doesn't touch the ground; whichever side it lands on loses.

He actually understands the rules quite well; they were designed specifically for Superman.

The reason why a typical tennis match is limited to a small court and has many rules is simply because most people don't have that kind of athletic ability.

For the members of the Sixth Anti-Air Division and Su Chen, the intensity was naturally a bit higher.

"The stuff from the Sixth Section of the Air Defense Department is indeed extraordinary."

Su Chen weighed the tennis racket in his hand.

This tennis racket is exactly the same as a normal tennis racket in shape, except that the material has been changed to a special kind of steel.

It is made entirely of solid steel and weighs about 20 kilograms when held in the hand.

Let alone playing tennis, it would be a formidable weapon even in a fight.

"Thank you for the compliment." Yuecheng Liu chuckled and said, "Our rackets were not very durable before, but they are much better now that we've switched to these."

"That's true."

Su Chen couldn't help but smile.

"Su Chen, you are the guest today, so you will be the one to kick off."

Yuecheng Liu handed a ball to Su Chen.

Su Chen took it, his eyes narrowing.

This ball is only about half the size of a fist, yet it weighs a full kilogram and feels quite substantial in the hand. Its density and hardness surpass even that of a block of iron.

Looking at how the others held their rackets, Cangjiao held the racket with both hands, one above the other, as if she were holding her heavy battle flag.

Hoshimi Miyabi held the racket with a reverse grip in one hand, her eyes sharp, as if she were holding a katana rather than a tennis racket.

Beside him, Yue Chengliu gripped the paddle tightly, making it seem like opening the Heavenly Spirit with one hand was no problem.

Judging from the steel racket, the intensity of tennis in the sixth lesson is indeed quite high.

However, the greater the intensity, the more he likes it!

"Then I won't be polite."

Su Chen decided to test the waters with a ton of force first.

Hoshimi Miyabi, being a cute girl chasing after Nini, also dodged several alloy doors along the way.

Even with the aid of weapons, their own strength is probably not much weaker than his.

With this thought in mind, Su Chen tossed the ball up and swung his steel racket fiercely.

The immense force propelled the racket forward at high speed, and the sieve-like racket face somehow managed to produce the feel of a banana leaf fan.

The wind that blew her hair across Yuecheng Liu's forehead caused her to unconsciously brush it aside with her hand.

boom!

The racket struck the tennis ball precisely, producing a loud thud.

The specially designed tennis ball, under pressure, flew towards Hoshimi Miyabi like a cannonball.

That one goal alone is enough to feed an ordinary person ten times over.

Most people wouldn't even have time to react, let alone answer the call.

"The power is a bit weak."

Hoshimi Miyabi shook her head slightly.

This amount of power was still somewhat weak for her.

She starts with an iaido stance, swinging the racket diagonally upwards from her waist with a reverse grip in one hand.

This was an extremely standard draw-and-swipe technique, so perfect that Su Chen's master-level martial arts deserved full marks.

In an instant, the racket precisely intercepted the tennis ball in front of him.

Then, a powerful force sent the tennis ball flying back at twice the speed it had come from, making a screeching sound as it rubbed against the air.

Yuecheng Liu smiled slightly and preemptively met the incoming tennis ball: "My turn, Su Chen."

This is a mixed doubles match, so it should be her turn.

She swung the tennis ball back with the force of a cleaver.

"nice shot!"

Su Chen exclaimed in admiration.

As expected of someone over 16, his swaying movements and every shot he threw were excellent.

"Thank you for the compliment, but Su Chen, you can rest assured and exert yourself freely. Section Chief Ya and Xiao Cangjiao are very strong, you know."

Yuecheng Liu said with a smile.

At the same time as Yuecheng Liu's words, Cangjiao's energetic voice rang out: "Su Chen, Su Chen, watch the game!"

The tennis ball was hit back with even more force once again.

Standing at 1.5 meters tall, Xiao Cangjiao swung his hands and unleashed a powerful aura reminiscent of a breakthrough to the Tengen stage.

"If that's the case, then I'm relieved!"

Su Chen's eyes narrowed, and he suddenly exerted force.

Facing the oncoming cannonball, the muscles in his arms were taut, and the veins stood out.

Ten tons of force, equivalent to 130 horsepower, launched at full power!

Compared to the first ball, this one was ten times stronger.

Under such immense force, even a tennis racket made entirely of steel will inevitably deform.

Fortunately, New Ellito has made great achievements in new materials, and the steel tennis racket in his hands is definitely a masterpiece.

This allowed it to recover quickly after deformation, instead of collapsing directly.

boom!

The tennis ball flew out like a cruise missile, far exceeding the speed of sound.

The tennis ball pierced through layers of air, leaving behind rings of sonic boom clouds.

In an instant, the ball, carrying immense heat generated by friction, slammed into Hoshimi Miyabi's front.
