Doomsday disaster: Stock up on billions of supplies at the beginning

Chapter 215

The fat fishman roared with a deafening roar, and a blue water column rushed over with a rumble, trying to stop Mu Yun from approaching. Mu Yun was so fast that he dodged the attack of the water column in the blink of an eye. The next moment, his figure appeared behind the fat fishman. A punch! "Crack!" A hideous dent suddenly appeared on the back of the fat fishman. "Ouch——" With a painful wail, the fishman's huge body trembled violently, trying to roll over, but because of the injury on his back, it couldn't do it at all. "What a strong defense!" Mu Yun was secretly amazed at the other party's hard back skin and the amazing defense. With Mu Yun's physique being fifty times stronger than that of an ordinary person, ordinary sixth-level creatures could not withstand his punch at all.

But this fishman was only seriously injured and could still fight back.

"Roar!"

Just as Mu Yun was stunned, the fat fishman waved his weapon, rolled up a huge wave and hit him hard.

Mu Yun's eyes focused and took out the Dragon Court Sword.

"Clang!"

Sparks flew, and the Dragon Court Sword collided with the harpoon in the fishman's hand, making a crisp and pleasant sound of metal clashing.

"Fuck!"

Mu Yun's eyes widened, the Dragon Court Sword was actually blocked!

How could the indestructible Dragon Court Sword be blocked by such a piece of broken copper and rotten iron?

Although Mu Yun only used less than 10% of his strength, the contrast should not be so strong!

The fat fishman seemed a little confused, not understanding why his casual heavy blow just now suddenly scared this little bug.

"There's something wrong with this weapon!"

Mu Yun instantly guessed that there must be something fishy about it.

The fat fishman, holding a harpoon, pounced on him with his teeth and claws bared.

Mu Yun quickly swayed sideways to avoid the opponent's attack.

He raised his right leg suddenly and kicked the fat fishman in the belly.

"Bang!"

The dull sound spread throughout the entire area.

The fishman flew backwards and fell heavily on the shallows.

And the harpoon in its hand also flew out of its hand and fell into Mu Yun's hand.

"What a special material, could it be some kind of ore on the seabed?" Mu Yun frowned slightly.

The long-handled weapon in his hand, which was similar to a harpoon, was as black as ink, with an uneven surface, and looked like it was polished from ordinary stone.

However, its weight was definitely more than a thousand pounds, and it could easily tear the steel plate.

The place where it collided with the Dragon Court Sword just now was not intact.

A small gap was clearly visible, the Dragon Court Sword YYDS.

"If this ore can be made into a weapon, or added to a steel alloy, the effect will be very good."

Mu Yun's eyes lit up and he became excited.

The most urgent task is to continue hunting the sea creatures to obtain crystal cores and break through the level as soon as possible.

Then go to the deep sea to find more such ores.

With a clear goal, Mu Yun was full of motivation and began to slaughter the Naga fishmen crazily.

The fat fishman was split in half by Mu Yun's sword, and he couldn't die any more.

After digging out the crystal core in its head, Mu Yun left.

The physique of creatures above level six is very strong, and he can't crush them directly like he does with those level three and four creatures.

But there is no need to waste energy to use a big move.

With the Dragon Court Sword in hand, two or three swords can solve the battle.

"I have 7 sixth-order crystal cores in my hand now, and I need 93 more to make a breakthrough.

I will kill for two more days. If I can't make it in two days, I will use low-level crystal cores to make a breakthrough."

Mu Yun thought about it and continued to move forward.

The effect of using low-level crystal cores to make a breakthrough is the same, but the absorption speed will be slower.

If there are enough sixth-order crystal cores, Mu Yun will definitely hope to make a breakthrough as soon as possible.

"Roar--"

Suddenly, there was an angry roar from a distance, and a giant python with green light all over its body swam over, opening its bloody mouth and biting towards Mu Yun.

This deep-sea giant python is extremely huge, more than 60 meters long, and is the same as the giant octopus, a sea king.

The giant python spits out its tongue, and the fishy wind hits people, which makes Mu Yun feel nervous.

This giant python's strength may have reached the peak of the sixth order and is about to break through the seventh order.

"Hey, it's like a pillow is sent to me when I'm sleepy. God helps me!"

Mu Yun grinned, holding the Dragon Court Sword in his hand, and faced the giant python.

"Ding!"

The giant python's thick tail swept over, carrying a powerful force.

Mu Yun crossed his arms in front of his chest to block the attack.

"Bang!"

Mu Yun felt that he

As if he had hit a high mountain, he couldn't help but take a few steps back.

"Hiss..."

The giant python spit out its tongue, and its cold eyes locked onto Mu Yun.

"Big worm, do you want to break through? Let me help you!"

As he spoke, Mu Yun took out a bunch of low-level crystal cores and controlled them to fly into the giant python's mouth.

The giant python, which was not smart enough, saw a lot of energy coming to its door, and swallowed it all.

"Boom!"

A surge of breath burst out from the giant python's body, and its breath rose steadily, breaking through to the seventh level.

The already huge body swelled again, becoming a behemoth of more than 70 meters.

"Not bad, not bad, one seventh-level can be equivalent to ten sixth-level ones, and it is more convenient to artificially cultivate mutant beasts, so there is no need to worry about the crystal core level being too low."

Mu Yun looked at his masterpiece in front of him with great satisfaction.

The seventh-level sea king has begun to show intelligence, has simple thinking, and has a high IQ, and is even a little cunning.

However, it met Mu Yun, and was doomed to be miserable.

"Roar!"

The giant python roared to the sky, and a sound wave visible to the naked eye spread out, causing ripples.

This sound wave contained a hint of spiritual power, and Mu Yun was caught off guard and felt dizzy.

Not only that, he also vaguely heard a dragon roar, which made Mu Yun's face suddenly change.

"This is a sign that the python has turned into a dragon. This sea king has a great background. Maybe he has eaten some strange mutant plants."

Mu Yun said secretly, but he did not panic. The domain was opened and he waited for the sound wave to end.

After the sound wave, the giant python did not care that Mu Yun was the great benefactor of its breakthrough, and rushed towards Mu Yun with its bloody mouth.

Mu Yun turned his wrist, a cold light flashed, and slashed at the head of the giant python.

"Dang!"

The python twisted its body to avoid the sword, and the sharp Dragon Court Sword slashed on the python's scales, emitting sparks.

Mu Yun's pupils shrank, "What tough scales!"

The python's scales were 20 centimeters thick, and the Dragon Court Sword slashed on its scales, leaving only a shallow scratch besides a spark.

The python swung its tail and lashed at Mu Yun.

Mu Yun stepped into the air and leaped into the air.

"Swoosh!"

The python's tail brushed past and smashed the reef on the side.

"This scale can be made into a protective gear later, and it will definitely be very useful."

Mu Yun thought in his heart.

The python missed the attack and immediately turned its head to chase Mu Yun.
