After a while, Lin Feng disappeared from everyone's field of vision, everyone looked at each other, and finally shook their heads in unison, silently returning to their posts, but they all thought in their hearts without exception: If he can come back safely, then he can really accept him as the deputy head of the regiment.

The cave is inclined to the ground at 60 degrees, and the walls are extremely smooth, densely covered with paw prints.

At first, Lin Feng still slowly climbed down along those paw prints, and when he entered the mist and couldn't see everyone's field of vision, he directly let go of the demon's wings, his body hovered in the huge cave, and slowly slid down with the pace of the ball.

The Demon Wings were extremely costly, but if they waited until the fifth order, the recovery speed of the Yuan Qi speed would be able to withstand this huge squander, which made Lin Feng look forward to it from the bottom of his heart.

He flew down all the way, and the four walls of this cave were generally smooth, and the diameter had always been more than ten meters, which faintly confirmed Lin Feng's guess.

A few minutes later, through the sharing of the vision of the ball, he still couldn't see the bottom at a glance, it seemed that the cave was very deep, and according to its direction, it had reached the belly of the small lonely mountain.

Suddenly, Qiuqiu sent a dangerous signal to Lin Feng!

A huge bull-like creature was rushing towards it, and what was surprising was that it had two crimson wings behind it, and it flew quickly.

Polar Yak!

Lin Feng was slightly startled, isn't this a creature that should live in the underground world, the Extreme South Domain, how could he also come here?

However, the individual strength of this kind of group surname beast is not strong, such as the one in front of him, it is only a third order.

Lin Feng was naturally not afraid, he held the knife in one hand, and when the fierce yak rushed forward, he just turned his body flexibly sideways, avoiding the crooked horns above his head, and at the same time swung the knife down, and with a soft "poof" sound, the huge bull's head flew to the wall, colliding and falling in the four walls of the cave like a stone rolling down from the top of the mountain.

Lin Feng sped up and slashed off his two horns with a single sword, and then picked out the red inner pill in his head, only to let his huge body roll down with a rumbling sound.

Leaning his body on the wall, Lin Feng rested slightly, and made a simple memory card to store the loot in, and then continued to fly downward.

The further down it goes, the thicker the fog becomes, and this fog is naturally also the cosmic source qi, thinking that there should be something below that gathers the cosmic source qi.

This kind of thing, without exception, is a treasure, Lin Feng's heart can't help but be a little hot, and if his guess is true, then the harvest will be even greater.

As he continued all the way down, Lin Feng once again encountered a tiger-shaped beast, also a third-order, and he hated Lin Feng's sword.

But Lin Feng faintly noticed that something was wrong, these strange beasts didn't look like they were wandering aimlessly, but more like they were forced to flee for their lives when they encountered something powerful.

Thinking of the occasional palpitating sensation, Lin Feng couldn't help but wonder if he was too impulsive?

But it has come to this, he can only be careful, and be careful!

After resting for a moment again, Lin Feng could already feel that he was not far from the lowest end of the cave, and the occasional beast roar made him understand that he was already very close to the bottom, and the only thing he needed to do now was to approach cautiously.

Lin Feng retracted his demon wings and walked down those dense claw prints, along the way he was lucky, he didn't encounter those strange beasts again, but picked up two crystal bombs.

This is a technological product of the Kasho era, and each crystal bomb can even deal damage to fifth-order creatures, but only damage.

After more than ten minutes, Lin Feng found that the fog was getting lighter and lighter, and he finally saw the situation in front of him, shrouded in a demonic red light!

Lin Feng's heart froze, and a cold air came out from the soles of his feet: as far as he could see, under the bewitching red light were huge glassware, which were filled with light blue liquid, and in those liquids, there were even different creatures soaked in them, from the red lion to the nine phoenix birds...... There are no less than 100 kinds of rampaging rats.

Many of the utensils had been broken, and the liquid was spilled all over the ground, and there were flesh and bones mixed with blood on the ground, and Lin Feng could even smell the pungent smell from afar.

Could it be that all those strange beasts escaped from here? Lin Feng guessed in his heart.

But soon he noticed something else unusual, the ground wet with liquid, there were footprints, scattered and messy, and when he looked closely, he noticed that there was a half-open door next to it, and there was a faint roar behind the door, as if some kind of creature was experiencing great pain.

There are zombies!

This was Lin Feng's first feeling, but how many zombies there were and what kind of strength they were made him wonder in his heart, and he couldn't advance or retreat.

Just as Lin Feng was lying on the cave wall, hesitating, a piercing scream suddenly came, and immediately after, he saw a black shadow shooting from the half-hidden door, extremely fast!

It was a swallow-shaped beast, but it was much larger, with seven or eight meters of wings outstretched, and it fled in panic.

Lin Feng didn't want to be exposed, his body retreated, his back was close to the cave wall, and Qiuqiu hid below under his order, taking the opportunity to slip in through the half-hidden door.

With the help of vision sharing, Lin Feng could also see the scene inside the door.

And when he noticed the situation there, he couldn't help but gasp: it was extremely wide, one hundred and ten square meters, but there were similar solutions soaked in foreign beasts all around, many of which Lin Feng couldn't name, and some of them had already woken up and stared wide in the glassware.

What frightened Lin Feng was not these, but those zombies wandering here, there were at least twenty of them, and of these twenty or so, five of them had reached the fourth order!

And there are two silver-white gates around it, both of which are open, and from Qiuqiu's field of vision, it can be clearly seen that there are other zombies swimming unconsciously outside those gates.

Their only pleasure is chasing the beasts that wake up and run away.

Suddenly, Lin Feng noticed the aura that made his heart palpitate again, but it came from the other side of the door, and it seemed that there was something so strong that it could not be blasphemed!

Retreat, or kill? Lin Feng was entangled.

It's a little more spectacular and maddening than he imagined!

Naturally, he already knew where this was—the inside of a starship!

In the glorious Cassiu era, scientific and technological civilization was also at the pinnacle of development beyond the reach of modern times, and various space warships were developed and put into use, and these warships were even capable of sweeping a wasteland.

According to the power of the battleship, it is divided into ordinary battleships, space battleships, interstellar battleships, super ocean-going battleships, and legendary god-class battleships.

Lin Feng originally thought that this was an ordinary or space battleship, but he didn't expect that this was actually a huge interstellar battleship.

But although his heart is hot, he also understands that after 10,000 years, this technological product may have long been dilapidated, and its power may not be as powerful as one-thousandth of that year, and, most importantly, there are zombies entrenched here.

It is very likely that there will be fifth-order zombies here, which he absolutely cannot fight against at the moment.

According to the structure of the battleship, the tail is a biological experiment cabin, which is dedicated to storing some creatures captured from foreign lands, and the control cabin is at the very front, and there are energy cabins, weapon mecha hangars, rest rooms, etc. in the middle, so if you want to control this behemoth, you have to face these zombies, after all, controlling this kind of thing is not something that can be completed in a while.
