"This is the cave demon?" Lin Ze stopped in front of a recognizable corpse, looked carefully, and as soon as he entered the wall, there was a large square, the tallest building was in the middle, and there were several small buildings on both sides, which looked like a mountain.

The cave demon looks like a beast that can walk upright, with fangs and teeth, a weapon made of bone, a tattered hide for clothing, and an ugly appearance with various cuticles.

"Judging by the decay, these cave demons haven't been dead for a few days, what the hell is going on here?" Leia looked at the corpses of cave demons scattered all over the building square, and her expression was solemn.

Who are the enemies of these cave demons? Judging from their various mutilated corpses, it should be physical damage, but the question is what exactly causes these damages, and where are the cave demons and their enemies now? Lin Ze looked at the quiet square, and it was strange everywhere.

"What's that?" Léa pointed to a strange pile in the far corner.

It seemed to be a pile of colorful rocks, Lin Ze was about to go over to check it, when suddenly, there was a distant sound from outside the wall, "Knock! Boom! Knock Knock~".

"Bloody drum, it's not good, it's a cave demon, they're coming!"

……

"Sizzle~I~Hungry~~~~~~" A girl who pouted her ass and lay on the bed like a cat, stretched out a hand hard, like a cliff fall on the edge of the cliff longing for a life-saving straw, and at the same time she blinked her eyes vigorously, posing a little pitiful.

"Humph!" Si Qin sat on the rocking chair with a big wooden bowl, eating by herself, this time she must not be soft-hearted, and remembered the big bowl of beef dry last night, most of which went into other people's mouths, Si Qin secretly regretted that this time the bubble cake was mine! These days when the cook is away, this is my ration!

"Woo~~~~" A certain kitten also got into the room and barked pitifully.

Damn, I have to prepare food for small pets, ah~~~~~ damn it, I hate guarding the house the most!

……

"Won't we be found out like this?" Sina whispered.

Lin Ze didn't speak, just shook his head gently, the three of them are now hiding in a small building whose gate has been destroyed, it seems to be a blacksmith shop, but it is scattered inside, obviously swept by the cave demon before, the drums and thunder in the square outside, a large group of cave demons are rushing forward to the main building, for these creatures living in the dark, hearing and smell are far more sensitive than sight, just now Leia has sprinkled the door of the blacksmith shop with the hidden powder used by their wandering warblers, as long as they don't speak loudly, The guys out there won't find out.

Lin Ze continued to look out through the cracks in the broken wooden boxes that covered the three of them, he really wanted to know who the enemies of these cave demons were, especially the corpses of the cave demons that had been cut into seven or eight pieces in the square, could it be that there were still moon elves here? I've never heard of what the Moon Elves look like, let alone seen living Moon Elves, including the descendants of the Nords who fought with the Moon Elves don't know what the Moon Elves look like, if it weren't for the fact that there are still many Moon Elf ruins in this world, I'm afraid most creatures will think that the Moon Elves are made up.

Just as those cave demons climbed the wall of the main building, the flowing stream on the wall suddenly emitted a red dazzling light, this is ~ scorching ray? Lin Ze suddenly had a strong sense of contradiction, this is not an ordinary technology, the equipment that can emit high-energy scorching rays is at least only available in third-order civilizations, that power~ Tsk, just look at those cave demons that fell in pieces, each of them was burned to char the moment they came into contact with the rays, and they didn't even have time to scream.

After a while, the rays stopped, and the energy slot on the wall dimmed again, this should be the energy consumed, waiting for the charge, this time Lin Ze knew how the cave demons attacked the wall, they used the method of consumption, and when the scorching rays protected by the wall were charged, they broke the energy circuit, and then they came in, God knows how many of them died before they used the most primitive bones to break the energy circuit on the wall, but who chopped those cave demons into pieces has not yet been discovered.

"Snort~" After a while, a soft sound came, Lin Zekeen immediately turned his gaze to the place where the sound came from on the second floor of the main building, there is a platform on the second floor of the main building, and there is a bunker like an arrow battlement on the edge of the platform, this should be the second line of defense of this fortress, and those scorching rays are to prevent the enemy from climbing the wall.

From a distance, a door opened on a wall behind the arrow battlement bunker, to be exact, a door was opened, and a tall shadow slowly walked out, Lin Ze's heart tightened, this is the moon elf? It was too tall, and with the height of the two-story building, at least 10 meters, a huge shadow was projected down, and it fell heavily in the middle of the cave demon in the square.

Colossus! This is the crystal energy rune colossus, Lin Ze almost exclaimed, a kind of crystal-like energy core as a power source of the rune colossus, judging from the three pairs of thick arms of the colossus, as well as the big knife held in the arms, Lin Ze finally understood how those cave demons died.

The colossus stood in the middle of the cave demon, and the upper body suddenly turned up, from slow to fast, driving three pairs of giant long arms, like a spinning top, blowing three whirlwinds of different heights, all kinds of ugly screams were endless, and the cave demon's bloody skin drum also beat more urgently, and the tide-like monster rushed to the whirlwind made by the colossus desperately~

"What are they doing here?" Sina couldn't help but ask, at this time, the shrill screams outside had long surpassed everything, and no cave demon could notice the small noise in the house next to her.

"Energy, they want to consume the energy of the Colossus, whether it is a Colossus or a creature, they need energy to move," Lin Ze explained in a low voice, "This is also the basis for the tactics of the sea of people." ”

"The crowd tactics ~ are very vivid, the Templar often organizes farmers to do this when they are fighting, and those necromancers", Leia thought about it seriously and agreed.

The colossus in the field is still harvesting the cave demon, Lin Ze secretly assessed it, the battle intensity of the colossus is afraid that it has reached the third order, coupled with the huge and heavy broadsword, the kinetic energy that is wielded is afraid that he can't stop it rashly, but the energy demand must be very large, huh? How long has it been since the Colossus slowed down? The huge power consumes a huge amount of power, and sure enough, the Colossus is running out of energy.

The sound of the bloodskin drum changed, and the interval between the two drums lengthened, and the cave demon who had just rushed towards the Colossus immediately retreated like a tide, away from the Colossus's attack range.

These cave demons are absolutely skilled in dealing with the colossus, at first in order to consume the power of the colossus as soon as possible, they went to death, but now that the energy is about to be exhausted, they immediately disperse.

The colossus finally fell, a group of cave demons swarmed up, and it was like a mess to the ground, after a long time, "Knock~~~~~Knock~~~~", the bloody skin drum sounded again, and the rhythm became very slow, just like when he came, the cave demon tide generally went away with the drum, and when he left, he also carried away the six huge long knives of the colossus together, it turned out that this was the purpose of the cave demon to attack here, damn, Lin Ze scolded in his heart, it was the metal of the third-order civilization as a weapon, It's a pity that recasting can also reach at least second-order materials.

Lin Ze and the others hid for a short while, making sure that the cave demon had gone away, and then they came out, and a large pile of corpses was added to the square again, as well as a pile of rubble that the colossus had turned into.
