It's been a week after Ethan exit the dungeon. And finally Lucas calls him to what to do next. When Ethan is entered in Lucas cell Ethan saw Lucas sitting on a chair with eye bags and messy hair. Ethan was surprised when Ethan saw Lucas, he was a little surprised he never saw Lucas like this.

Ethan just sits down opposite to Lucas without saying anything.

“Little brother, don’t bother with my appearance, I just didn’t get any sleep for two days.” Lucas said while yawning

“Little brother, your training is finished now.” Lucas said with a smile.

“Then tell me how we are going to leave this place.” Ethan said impatiently.

“To leave this place? We couldn’t as you know there is no exit in this place.” Lucas said. Ethan gives him a cold stare.

“Hahaha, little brother, I am telling you the truth, we can't leave this place.” Lucas laugh and said, “but it doesn’t mean outsider can't come here to help us.”

When Ethan heard this he opened his eyes wide, “you mean you want to destroy concealment relic?”

“Bingo, little brother, we are going to destroy concealment relic.” Lucas said. Then he said in a serious voice “it will be dangerous if we able to destroyed concealment relic outside help will come. But I don’t know how long will it take. If people that supervise this place found us before help arrive, we will be dead meat.”

“If we died in process than be it.” Ethan said in determining voice.

“Hahaha, then we can officially start our mission” Lucas said.

***

Next day at dawn, Ethan, Lucas and Anna came to cave in the hunting ground.

When Ethan saw the cave, he frowns “why we are here.”

“Because that relic is there inside this cave.” Lucas said.

“I have been living here for a year in this cave why didn’t I know?” Ethan said as he looked toward Lucas.

“Little brother, you only stay here to sleep and if this place was easy to find, we would not be here right now. Lets go we don’t have time.” Lucas said has he starts walking.

Ethan and Anna follow behind.

They walked until they saw the end of the cave. Ethan looked around and there was only a wall. Ethan looked at Lucas questionable.

Lucas tosses a blue ball at ground and the ball exploded, the ground beneath them shake a little and a hidden stare passage that go to the underground came to their site.

They entered in, at the end of stare there was a door. Lucas took a deep breath before gesturing Anna. Anna shot her gun at the lock of the door and it opened.

When they enter they saw a spacious hall. In the center of the hall there was a big black serpent. When Lucas saw the serpent his face changed.

The black serpent is tier 4 beast at a young age and become commanding tier 0 beast at adulthood. Lucas wants to leave the place right away because he didn’t expect a tier 4 beast to appear, he thought at most there will be a tier 3 beast at most and Anna and Ethan can be able to deal with it. But it was to late the door they came from shut automatically. When the door shuts the attention of the serpent came toward them.

When serpent saw them, it hissed and start coming toward them. Anna was fastest to move, she starts running at side while shooting at the serpent. That diverts the attention of the serpent from Lucas and it start chasing toward Anna. Its body was really big it was about 80 meters in length. Ethan, who was shocked when he saw the serpent snap back and also rushed toward the serpent.

Ethan swings his sword at the back of the serpent, but it only leaved a scratch on its black scale. Ethan didn’t loss his will and continue attacking. He used his all strength in his swings, but in vain.

Anna was trying her best to divert attention of the serpent toward her, she was trying to shoot at the eye of the serpent while running.

When serpent saw that it can't able to catch Anna it start ignoring her. It turned around and saw that a little human was trying to penetrate his scales, and moved toward it.

Ethan was trying hard to make a fatal wound when he heard Anna panic shout “Ethan!”

Ethan turns around and saw serpent wide opened mouth, but before he can do anything he was swallowed whole.

When Lucas saw this he screamed “NO!!”

Anna, who was shooting at serpent stopped running when she saw that Ethan was eaten alive. She just stops running when the serpent tail came toward her and looped around her and start tightening it. Anna struggle to get free, but in vain. Anna takes out a dagger and start attacking at the serpent, but she was not powerful enough to penetrate its skin.

Lucas, who was standing at the side was in shock because of Ethan snap back when he heard Anna screamed in pain and saw that the serpent was tightening his tail and was about to crush Anna.

He hurriedly takes out bomb relics that he has prepared before and throw toward the serpent. Bombs denoted at serpent body and there was burn mark on serpent skin.

Serpent whose attention was on Anna feel pain it threw Anna at side and start moving toward Lucas. Anna bumped in wall and throw mouthful of blood.

The serpent was about to swallow Lucas when it absurdly twisted its body and smashed into the wall beside Lucas. Then serpent start smashing its body on the wall again and again. It looked like it was in pain.

Lucas was about to get smashed by the serpent body, but was rescued by injured Anna. Serpent continues its beserk attack on the wall. There was blood coming out of its mouth.

Lucas and Anna were puzzled, when they saw that serpent suddenly gone berserk. But Anna did not let go this chance and start shooting again this time she was using another gun. She didn’t like to use this gun because it absorbed to much aura, but she has no choice. One of her bullets went through serpent eye. The serpent hissed in pain but it didn’t stop and smash its body into the wall again.

In the end the serpent fell on ground its body start twitching uncontrollably. Anna, who was attacking it from afar came at the serpent face in second and barge ten bullets in serpent good eye. It hissed again and smash its face at the wall again, but at that time Anna was long gone from her spot.

This time serpent didn’t lift its head. When Anna saw that serpent was dead, she releases a sigh of relief. Lucas, who was standing at side rushed toward the serpent body and start stabbing its skin where its stomach was with the dagger but it did not pierce through at all.

“Anna what should we do Ethan is still in its body, he may be alive.” As Lucas said this a sword blade came out of serpent body. Ethan made a cut from the inside serpent body and came out of it.

Ethan condition was not looking good, some part of his body was burned because of acid inside serpent stomach. His left arm was bleeding non-stop.

When Ethan came out of the serpent body, he throws a mouthful of blood. When Ethan was swallowed whole he start cutting flesh from inside as a last resort, but serpent start smashing its body in the wall because of this Ethan also got some internal injuries.

When Lucas saw that Ethan was alive, he hugged him giving no heed to sticky liquid that was all over Ethan body.

“Little brother, I am happy you are still alive, oh what would I do if you died.” Lucas said in a cheerful voice.

Ethan pushed Lucas at side and take out bandage from Lucas bag and start bandaging his left arm.

When Lucas saw this he let out a sigh, “before taking the bandage from Ethan hands and start bandaging Ethan’s arm and said “little brother let me do it.”

Ethan said nothing. After bandaging Lucas looked at Anna, who was sitting on the floor. “Hey, did you get injured?”

“I sprain my foot a little, but it's nothing give Ethan a vital portion.” Anna said.

Lucas takes out two vital potions and give one to Ethan and other Anna.

Let's take a rest here a little, then continue. I didn’t think that those people would have a black serpent as a guard. Thankfully we made it alive I don’t think that there will any more danger in there.” Lucas said as he also sit down on ground.
