Lord of the Abyss

The sudden appearance of Ziyue and the system prompts ringing in his ears shocked Wu Feng. Looking at the time, it was already 15 o'clock. Generally speaking, it would be dawn at this time!

On the 700th floor, it usually dawns between 9:00 and 11:00, and the first light of dawn will spread all over the earth. But on the 799th floor, it is now 15:00, and the moon appears! In another 6 hours, it will be 21:00 noon.

What Wu Feng didn't expect was that even if the moon appeared, it would also affect the environment on the 799th floor. The effect would probably be no worse than the Southern Barbarian invasion.

The levels of all monsters are increased by 3 levels, the refresh efficiency is increased by 100%, the boss refresh rate is increased by 100%, and there is a 20% mutation rate. This is completely the content of the advanced challenge!

Wu Feng also reacted: "Is the 799th level also a level with abnormal celestial phenomena? The previous three-body celestial phenomena and ten-day celestial phenomena caused that layer to fall into the hands of the abyss demon."

"We on this level won't be so unlucky!"

Wu Feng judged that the purple moon that appeared now was an abnormal celestial phenomenon, not an ordinary moon. If the 799th floor had a purple moon, wouldn't it happen every night in the future? If they are unlucky, the senior lords will die.

[Almighty Genius]: "What the hell! We are done with area 012062033! The Southern Barbarian invasion + Purple Moon Shine, all dead! Burning all eight wastes, are you happy now?"

The number one all-around genius of the Big Head Clan couldn't help but curse in the regional channel. He was very unlucky to encounter a mutated blue boss, because the boss level had also been raised to level 21, and now his purple heroes were being destroyed. Rub it on the ground! This is simply unreasonable.

Originally, if it was just the arrival of the purple moon, [Almighty Genius] would not be too strenuous, but now with the invasion of the Southern Barbarians, after the difficulty is superimposed, it is completely two concepts.

[Almighty Genius] Such a top genius has suffered losses in his territory, so he naturally wants to curse the people who caused all this.

At this time, Fen Jin Bahuang had no time to care about what the [Almighty Genius] said, because he himself was now in trouble.

A new mutant boss also appeared around his territory, and his heroes were suppressed due to their level difference. Even after the second mutant blue boss appeared, defense towers in his territory were demolished.

At this time, Fenjin Bahuang must deal with a steady stream of bosses with all his strength, and there is no time to argue with the [Almighty Genius].

…

"Is this the mutated boss? After the mutation, the quality has been improved by at least half a level!" Wu Feng also encountered a mutated blue boss.

Just near the Holy Light Tower, a little demon leader with a third hand rushed out. After it mutated, its level and attributes also improved. The Holy Light Tower couldn't kill it instantly even with two rounds of Holy Light Bullets.

Today's Holy Light Tower has 10 Holy Light Bullets in one round, but it still cannot kill the little devil boss. Its combat power is probably close to that of the purple boss.

Wu Feng discovered this immediately. He directed the powerful shooters around him to attract the attention of the mutated boss. This blue hero had been gaining experience near the Holy Light Tower for a long time and has now reached level 4.

A level 4 magic shooter should have been able to challenge the blue boss alone, but this mutated boss is relatively tough, and the magic shooter cannot defeat it alone.

And Wu Feng didn't need him to win the mutated boss in a duel. He just needed to hold the boss back and give the Holy Light Tower a few more rounds of Holy Light Bullets.

So after some maneuvering, the mutated boss finally died under the fifth round of Holy Light Bombs from the Holy Light Tower. After the death of this boss, the experience value provided to Wu Feng was comparable to that of two blue bosses, and its drops The items are pretty good too.

"One blue crystal and one blue key were released! This mutated boss has a higher drop rate than the ordinary boss!" Wu Feng was refreshed. After seeing the mutated boss drop, he immediately asked the magic shooter to Send it back.

The blue hero was very fast, and his position was only a few hundred meters away from the lord's cabin. In less than 2 minutes, a powerful shooter named Li Ying brought back the dropped object.

Wu Feng's blue keys have reached 6, and now the probability of collecting 10 blue keys has increased a lot.

"Lord, the demon lairs in the canyon are simply furious! They are attacking our defense line crazily! There are several mutant bosses among them!"

Urgent news came from Wei Gusi. After Wu Feng changed his field of vision, he saw that there were more demons in the canyon, and their levels were generally raised to above level 11. Even the little demons were above level 10.

Every time a monster breaks through level 10, its attributes will be significantly improved. The attributes of a level 11 little devil are 50% higher than those of a level 8 devil. Without the Tower of Death, even the Flame Tower and Thunder Tower cannot kill the little devil instantly.

The little devil is nothing, the main reason is that the more advanced flame devil and harpy devil have reached level 18, and they can survive two attacks of the flame tower.

Attacking more means that the killing speed of the defense tower will decrease, and the demons will naturally gather more and more, not to mention there are many bosses among them.

The Goblin Warrior was near the defense line at this time, and he counted subconsciously: "One, two, one..."

"One, two, one..."

It seemed that the Goblin Warrior still couldn't count the number, but Wu Feng was able to count the number of bosses rushing out of Devil's Canyon in one go.

There are 12 green bosses and 5 blue bosses, including 2 mutant bosses! One flame demon's right hand mutated to a huge size, and the feathers of the leader of another harpy demon were all turned into inverted feathers.

These two bosses pose a great threat to the defense line. The flame boss can throw fireballs hundreds of meters away. After a few fireballs, a green defense tower will be crumbling.

The eagle boss can drop from the sky and directly attack the crossbow tower, and its durability will also decrease quickly.

Wu Feng frowned. Wei Gusi and Qi Yalu were both furiously dealing damage to the two bosses, but their attacks would probably also destroy one or two defense towers.

At this time, the role of the tower defense summoning card came into play. He immediately rushed to the canyon defense line. Before the defense line was breached, he placed three more defense towers behind him.

They are the newly obtained Death Light Tower and two Repeating Crossbow Towers. The defense tower blueprints still require construction time. Summonable cards can directly summon tower defense, which can be of great use at critical moments!

After a repeating crossbow tower and a turret on the first line of defense were destroyed, the defense line composed of the death ray tower and the repeating crossbow tower blocked the enemy again.

The Death Light Tower is a blue tower defense, and its lethality is also very good.

Death Light Tower: Medium-sized defense tower (excellent quality), area: 40 meters * 40 meters. Attack power 150-300 points, can attack 3 times per second, range 300 meters, defense power 120 points, durability: 30,000 points.

Additional skills: death ray attack, death ray.

Death light attack: It can cause damage equal to 2 times the attack power to enemies in a straight line. The attack distance is 1.5 times the range, and the cooldown time is 10 seconds.

Death ray: After charging, it shoots a continuous death ray, causing damage of 1.5 times the attack power every second, with a 1% chance of causing instant death (up to killing bosses with blue quality). The lower the enemy's HP, the more instant death will be caused. The higher the probability, the maximum duration is 5 seconds, and the cooling time is 30 seconds. Every time the death ray kills 200 enemies, the death ray tower's attack power increases by 10 points.

The Death Light Tower is a very good blue tower defense. Its attributes are more powerful than ordinary blue tower defense. With the addition of the Death Light Tower, the death light attack and death ray can be used alternately, which can kill a large number of enemies.

Combined with the Tower of Death, death ray attacks and death rays can greatly damage enemies, especially the death ray's ability to instantly kill. The lower the enemy's health, the higher the chance of death.

The Tower of Death is a defense tower designed to reduce the enemy's health. The instant death effect of the death ray is very useful against enemies with residual health.

Many enemies with about 10% of their health left were instantly killed by the death ray. Turning on the death ray for 3 seconds is enough to kill a large number of enemies!

After the Death Light Tower was built, a death ray instantly killed a large row of demons. A blue little demon leader was instantly killed by the Death Light Tower, and a blue key dropped on the spot!

[Ding... Successfully kill the blue boss during the Nanman invasion. According to its level (level 15), you will get 2 challenge points. 】

One round of death ray, with a range of 300 meters, killed hundreds of enemies instantly. After two rounds, the death ray killed more than 200 enemies, and the death ray tower's attack power immediately increased by 10 points.

Combined with the power of death given by the Death Tower, the Death Light Tower's damage increases very quickly. If this blue defense tower continues to grow like this, its power will be comparable to that of the purple defense tower.

Wigus also used a fireball to kill the harpy boss. The mutated boss was also killed and dropped a blue key.

[Ding... Successfully kill the blue mutant boss during the Nanman invasion. According to its level (level 21), you will receive 4 challenge points. 】

Seeing that everyone had amazing results, Qi Yalu also started continuous bombing, sending out howitzers continuously, destroying the flame boss who was attacking her from a distance. Wu Feng got the 9th blue key!

[Ding... Successfully kill the blue mutant boss during the Nanman invasion. According to its level (level 21), you will receive 4 challenge points. 】

Seeing that many demons and bosses in the canyon were quickly cleared away, before Wu Feng had time to be happy, he saw a huge figure walking out of the depths of the canyon!

It was a tall demon with a height of 10 meters. It had four arms and exuded a violent aura!

Wu Feng's eyes widened: "This is...the purple mutant boss?"
