4 Trump card

*KABOOM*

A huge explosion went off on a mountain as two experts clashed against each other.

The explosion served as a cracker compared to the series of explosions that followed it. The mountain and the nearby lake were destroyed in a matter of minutes.

A white shadow flashed from the sky as it firmly impacted the ground creating a huge crater around, an old man could be seen getting up from the crater.

He looked to be in his 60s and wore a white robe which was now stained with blood. The man looked towards the sky as he yelled, "Who are you? I have led a very peacefully and never antagonized anyone in my life. why so serious? "

A middle-aged masked man, who wore a black changshan stood on his flying sword as he looked back at the old man, "Today, next year would be your death anniversary."

He then shot down a rain of palm strikes onto the old man, who had proceeded to make his escape.

"Damnit! Who would have the heart to actually send an assassin onto this peace-loving old man?!", the old man flew on his flying sword as fast as the wind towards the remote mountainous regions in an order to lose the enemy off his trail.

But clearly luck wasn't on his side as his enemy followed closely behind. The chase went on for hours, feeling his energy depleting, the old man had decided he had no choice but to confront the assassin.

The old man hid beside a mountain cliff and awaited the assassin, after which he proceeded to counter-ambush the latter and both suffered severe injuries.

"Damnit!", the old man spat out blood as he looked at the injured assassin. Although both seemed injured severely, the old man knew he had taken greater amount of damage and he had to finish the fight in the next move or else....

The old man used a forbidden technique and started burning his life force as he suddenly amassed a great amount energy within his body.

[TRI-COLOUR UNICORN FIST]!

The old man used all his energy into his attack and filled the whole region of hundred Li around him with the three colours of unity. The surged energy fell onto the pitiful assassin who couldn't avoid it on time as his injuries dragged him down.

After the tri-colours from the attack disappeared all that was left behind was a huge crater with the assassin standing firmly in the middle of it.

*Arghh* *cough*

The assassin spat out blood as the look in his eyes dimmed a little. Clearly he had suffered severe injuries.

As the assassin looked towards his left side, he was shocked to find his left arm was blow away by the attack!

This was a huge loss for the assassin since he was a left-handed, single, swordsman.

"You...ruthless!" , the assassin finally spoke.

"Go to hell!", the old man leaped into the crater and wrestled the assassin. Both of them were completely depleted of their energy, all they could do now was use their bodies to kill the latter.

A fierce fight of experts had turned into a ferocious wrestling match as the two parties wrestled bravely against each other.

But it seemed as if it was tie, since nobody managed to gain the upper hand!

Having no other choice, the assassin took off his belt and threw it at the old man.

The old man knew that there was probably something fishy about the belt so he simply dodged it and then pranced towards the assassin, who by then had removed his underpants.

The old man was greatly disturbed by the assassin's actions and took two steps back in surprise, "Y-you what are you doing?!"

"T-there is no other choice! I can't take you on with my current strength...this is my final trump card!", the assassin's voice sounded embarrassed but nevertheless, it was full of confidence as he threw his underpants towards the old man.

The old man didn't dare to underestimate the enemy as he then stepped back to dodge the underpant-attack but he tripped over a piece of rock and fell down.

This was practically a heaven-sent opportunity for the assassin as he shouted, "Go Boom!"

The pair of underpants that fell next to the old man suddenly brightened and then...they exploded.
