The Age of Lords: I, the Only Top-up Player in the Entire Server

　　Therefore, he has his own unique way of analyzing customs clearance requirements.

　　The system prompt just mentioned several key points.

　　Thirty minutes countdown, twenty-five minutes countdown, extra boss, unexpected harvest.

　　A total of six floors, the Lord of Calamities.

　　The way to play in this secret realm is very simple, as long as you kill all the monsters before the countdown on each floor ends, you can enter the next floor.

　　After passing five floors in a row, you can meet the Lord of Calamity on the sixth floor.

　　If you kill the Lord of Calamity, you will be cleared.

　　But in addition to ordinary monsters, the system also mentioned additional bosses.

　　Killing them will yield unexpected rewards.

　　The harvest here, Lin Chen has two guesses.

　　The first, may be an added bonus.

　　Killing the boss and giving extra rewards is a windfall.

　　Second, it is very likely to be related to the final customs clearance.

　　Perhaps killing the Calamity Lord will be related to these additional refreshed bosses.

　　As for what it was, Lin Chen had to play a dozen to find out.

　　Whether it's for extra rewards or the last Lord of Calamity, Lin Chen must fight this extra boss.

　　The requirement to summon additional bosses is to kill all spawn monsters within 25 minutes.

　　This is easy to understand.

　　Just when Lin Chen was thinking about these key points, the monsters in the Tower of Calamity had begun to refresh.

　　The space around Lin Chen and others began to distort.

　　Immediately afterwards, in the twisted space, black silhouettes quickly emerged from the twisted space.

　　There are some undead monsters, and there are a lot of them.

　　There are fourth-order skeleton archers, fifth-order skeleton epee, and sixth-order necromancers.

　　Densely packed, the number is probably more than 30.

　　Of course, this is not a big problem for Lin Chen, after all, he brought in more than [-] troops.

　　And the rank is higher than these monsters.

　　"Fight!"

　　"Prepare the formation, explode the earth dragon, the blood-raging orcs are in the front, the popular archer, the soul eater, and the dragon hunter are in the back, and the gryphon knight harassed in the air. Quick battles, get them in 25 minutes."

　　Lin Chen gave an order in a low voice.

　　The heroes acted immediately, mobilizing troops to form a formation.

　　The [-] explosive earth dragons scattered, forming a circle with the blood-raging orcs.

　　Protect the crispy output occupations such as dragon hunter, popular shooter, soul eater, etc. in the middle.

　　As for the Griffin Knights, all take off.

　　Led by Garou, support is always in the air.

　　Soon, the two sides went hand in hand and the battle began.

　　There are only 30 undead monsters, and the highest is only Tier [-], which is not a big problem.

　　As soon as the war begins, they die in pieces.

　　The dragon breath of the explosive earth dragon and the arrows of the dragon hunter are all powerful weapons.

　　In just ten minutes, the battle was over.

　　"You have killed all the monsters within 25 minutes, the extra boss will be refreshed soon, please be prepared."

　　The system beep just went off.

　　Lin Chen felt the ground under his feet vibrate.

　　Immediately afterwards, the ground ahead quickly cracked and collapsed, revealing a large hole.

　　A behemoth emerged from the cave.

　　Sen Bai's bone body, human shape, holding a bone sickle, wearing heavy armor, and wearing a crown diagonally on his head.

　　Inside the hollow skull, two soul fires swayed wildly.

　　"Roar!" The big guy roared, dragging his bone sickle towards Lin Chen.

　　Lin Chen ordered the attack while checking the attributes of this big guy, as follows:

　　【Bone King】

　　grade:

　　Health: 10 billion

　　Defense: 5

　　Attack Power: 3

　　Speed: 140

　　Skill: Bone Grace:...

　　Roar of Kings:...

　　Soul Burning:...

　　Description: The former king, after he died, absorbed a large amount of undead energy and became the undead king.

　　Seeing this attribute, Lin Chen raised his eyebrows.

　　Good guy.

　　 Level bosses, but only extra bosses.

　　It seems that the guy on the top called the Lord of Calamity is definitely not weak.

　　There's no way, you've come, you can't quit halfway!

　　So, with an order, the attack began.

　　More than [-] troops were fully fired.

　　Among them, the dragon hunter does the most damage.

　　Countless arrows cut through the sky and fell on the Bone King, dealing critical damage one by one.

　　The Bone King let out a roar, and his health dropped slowly.

　　After paying hundreds of troops casualties, he successfully killed the Bone King.

　　This guy's [-]-meter-high body fell to the ground instantly and fell apart.

・・・・・・・・・・・・・・

　　And where it died, a skeleton treasure chest appeared.

　　Lin Chen quickly ran over and opened the treasure chest.

　　"You have opened the Catastrophe Treasure Chest and obtained 1000 million basic resources, Citizen Refresh Card*10, Undead Spirit Soul*10, Gold-level Equipment Treasure Chest*3, and Seal of Light*1."

　　A fairly generous reward has been credited.

　　But they were all ignored by Lin Chen.

　　His attention was attracted by the thing called the Seal of Light.

　　【Light Spirit Seal】

　　Description: It can be used to seal, suppress the dark breath, and weaken the strength of the designated enemy in a short time.

　　Seeing this, Lin Chen understood.

　　He knew what the point of these extra bosses was.

　　Killing them can indeed get extra rewards.

　　But the most important thing should be the seal of light.

　　If Lin Chen guessed correctly, the Lord of Calamity on the sixth floor must be outrageously strong.

　　Going to war directly, not to mention failure, but certainly to pay a great price.

　　Therefore, it is necessary to use this seal of light to weaken the strength of the Lord of Calamity, and then complete the kill within the specified time.

0 ......  

　　"It shouldn't be wrong, this is the correct way to clear the level." Lin Chen clenched his fists and threw the Seal of Light into his backpack.

　　With a few minutes left in the thirty-minute countdown, Lin Chen ordered to rest.

　　Wait thirty minutes.

　　The ground beneath Lin Chen and the others was rumbling up.

　　After dozens of seconds, the ascent stopped, which should be the second floor.

　　"The countdown to the second floor of the Tower of Calamity begins, please kill the monsters on this floor within [-] minutes."

　　Then, the monster appeared, and Lin Chen ordered an attack.

　　The number of monsters on the second floor has risen to 40.

　　But no problem.

　　Successfully ended the battle within thirteen minutes.

　　Then there is the boss refresh.

　　This refresh is a undead knight king.

　　No need to say, just start it.
