I originally thought that the most powerful person I encountered in the castle would be Aqina, but I never expected that several of her subordinates who considered her daughter would be so fierce.

It is obviously a monster gathered by mutated flies, but it is not afraid of fire or grenade explosions, and even flash bomb attacks are completely ineffective.

Pure physical attacks are also effective. The Xuantian Sword swung rapidly can easily kill those mutated flies, but this thing is too small and there are too many.

The most troublesome thing is that the living mutant flies will devour the corpses of the killed flies, quickly regenerate and separate new mutant flies to supplement the losses, and have almost unlimited regeneration capabilities.

Moreover, the battle also attracted another monster, Archina's daughter. As the three sisters took turns to fight to reinforce each other, Li Xiao was stunned and lost his temper.

The sword energy released is indeed very powerful. Those flies flying everywhere will instantly turn into powder after being hit by the sword energy.

It's just that those mutant flies are not uniform, and the sword energy energy cannot be transferred between those flies after hitting the flies. Therefore, each sword energy attack only kills a small number of mutant flies.

When the loss of mutant flies reaches a certain level, they will quickly escape to eat. With the supplement of organic food, the mutant flies will quickly divide and return to their original numbers.

What depresses Li Xiao the most is that after the corpses of the flies killed by the sword energy were turned into powder, no energy crystals were condensed. Therefore, entangled with these monsters was a waste of time and energy.

After struggling with several monsters for more than ten minutes, more than half of the energy in the Dantian was consumed, but no loot was obtained. Fortunately, there was still a lot of energy in various energy storage equipment, so I had no plans to leave for the time being.

However, considering that there was no loot at all from the flies, it was a waste of energy, so I changed my strategy and directly relied on the body-protecting energy to block the attacks of the bloodthirsty flies, and rummaged around the castle.

Looking for relevant information, if they find something valuable and pack it away directly, these monsters will have nothing to do with Li Xiao.

The protective aura can easily block the attacks of those bloodthirsty flies flying everywhere. If these flies gather into one person and come to fight with him with a weapon, only one roundhouse slash can defeat the gathered body.

Therefore, a few monsters could only surround them and constantly harass and curse: robbers, thieves, gangsters, shameless people, they will not die easily.

But Li Xiao pretended not to hear it at all and still searched the entire castle regardless.

I don’t know if it is because of the unique urinary nature of the game world, but the flaws of these monsters were actually recorded in the diary. Although these monsters are not afraid of fire or light, they are very afraid of cold.

After discovering this secret, it becomes quite simple to deal with it.

Although spring has already arrived, and it is difficult to release ice spells in this world, there is a tank of liquid nitrogen stored in the storage space.

In order to bring the three of them together, when the monster Daniela transformed into a human form, she did not perform a roundhouse slash to directly defeat the opponent. Instead, she easily forced the opponent to attack and searched for gold, silver and jewelry everywhere in the castle.

Originally, Daniela was afraid of being directly defeated by Li Xiao with a sword, so she just hid in the distance and threw various weapons. However, she saw that Li Xiao no longer directly rushed towards her body and defeated her with a sword like before, but was thrown out.

The weapon made the rat scurry away, so it became much more courageous.

With the continuous progressive attacks, Li Xiao also narrowly avoided those attacks and hid everywhere.

Soon the second sister named Cassandra also finished eating and replenished her body and re-condensed into a human form, joining in the pursuit of Li Xiao.

Li Xiao was still being chased and was hiding in various places. His situation seemed precarious and he looked like he might be hacked to death by the two girls at any time.

Not long after, the eldest sister Bella also successfully completed the food replenishment. After recovering a sufficient number of bloodthirsty flies, she returned to human form and appeared behind Li Xiao.

"Daniela, Cassandra, come together and eat this damn robber." The eldest sister greeted and quickly rushed towards Li Xiao, and the other two also responded and rushed towards him together.

Li Xiao squatted down directly, seemingly giving up resistance, but when the three monsters almost pounced on Li Xiao, he jumped up instantly, and a tank of liquid nitrogen appeared in the middle.

This sword attack hit the liquid nitrogen tank.

Bang!

The nitrogen tank burst into pieces, and the liquid nitrogen splashed out instantly. The people who surrounded and killed Li Xiao didn't even react. They were splashed with a large amount of liquid nitrogen and their body temperatures dropped sharply.

The ability to move was suddenly slowed down by ten times, and after being attacked by the rapid cooling, many bloodthirsty flies also joined together to keep warm, instead of turning into bloodthirsty flies flying in the sky and escaping.

Li Xiao also reversed his light body technique when he jumped up, and quickly fell back to the ground, carrying a huge sword energy ball, which hit the three people gathered together...

The three sisters failed to turn into flies and fled. The energy of the sword energy was transferred between many bloodthirsty flies. In an instant, all the bloodthirsty flies were eroded, and their bodies quickly began to become petrified.

"Why...why are you doing this to us...what have we done wrong...why are you doing this to us..."

When the three of them died, they let out shrill screams with questioning voices. Their vividly simulated eyes were full of despair and fear, which made Li Xiao feel quite uncomfortable, and even felt a sense of guilt.

However, some mental interference was eliminated in an instant. These girls had been killed by Aqina long ago, and even their corpses were eaten clean by a large number of mutated bloodthirsty flies.

Now, although these three people still look like humans, they are actually just a bunch of mutated bloodthirsty flies that eat human flesh and blood...

Without saying anything else, he quickly replenished the true energy in his Dantian, and then released a sword energy that rushed towards the three of them, completely eliminating the last trace of life.

The body was completely petrified and shattered, and finally turned into powder and scattered on the ground. However, among the pile of wreckage, there was a piece of energy crystal condensed. There was only one piece, or to be precise, three pieces were fused together to form one piece.

The size is unexpectedly large, as big as a fist, much larger than all the crystals harvested in the werewolf cave combined.

Even in this huge crystal, not only the energy of the sword was found, but also the fluctuation of mental power was sensed. It was somewhat similar to the crystals obtained by killing the monsters parasitized by Pukara, and should also be used to cultivate mental power.

After collecting the loot, we continued to search the castle.

Without the interference of the three fly sisters, the search speed became much faster. It was soon discovered that there was a huge underground world in this castle. Instead of carefully looking for the entrance to crack the mechanism, an entrance was directly blown up.

Directly entered the underground passage.

I don't know if it was a coincidence, but after entering the underground passage through the exploded entrance, I met the eight-foot-tall Aqina immediately.

I thought it would be hard to fight with the big boss of the castle, but the result was a bit unexpected. Just a slash of sword energy instantly knocked the opponent back to his original form, turning into a huge monster similar to a flying dragon.

The flying dragon directly collapsed the underground tunnel and broke through the roof. It looked like it was very powerful.

Li Xiao was also prepared for a protracted war. He quickly took out the electromagnetic gun and even loaded it with depleted uranium armor-piercing bullets. He aimed at the weirdo who was completely integrated with the weird flying dragon and blasted it out with one shot.

puff!

The depleted uranium bomb penetrated the flying dragon's body easily, and the flying dragon also fell directly from the sky, smashing the roof of a house. After waiting for a while, the flying dragon did not fly again.

When I took a closer look, I realized that the life energy was rapidly passing away, and it was actually killed by a shot from the electromagnetic gun...

This result was indeed a bit unexpected, but before the vitality of the mold on the corpse was completely dissipated, a sword energy was quickly condensed and released.

The battle just now alarmed some monsters similar to humanoid bats around, so there was no rush to collect loot.

Considering that electromagnetic weapons can do enough damage to such monsters, they quickly took out their electromagnetic rifles and killed the monsters that were flying from all directions.
