Wu Feng had a wave of special permissions, allowing him to have a large number of high-level props, and Wu Feng asked Geralt to teleport to the 'Tiankeng' defense line with some resources and newly obtained items and props.

After Geralt appeared in the Tiankeng defense line, he immediately began to strengthen this defense line according to Wu Feng's wishes.

The first is to use Wu Feng's remaining legendary quality tower defense evolution tower to evolve the outermost star tower into a planetary tower!

This is Wu Feng's third legendary tower defense, and the reason why he chose to evolve the Stellar Tower is because the planetary tower is the same as the Stellar Tower, the more powerful the number!

Gather three planetary towers, but you can activate additional abilities, and the ability to activate the legendary tower defense joint activation should be very good.

Wu Feng wants to get the three planetary towers together first, and then have the opportunity to evolve other defense towers in the future, anyway, he will always get more tower defense evolution cards through the lottery in the future.

At the same time as evolving the Star Tower, Geralt also used a copy card to place another Star Tower in the sinkhole defense.

Now the sinkhole defense line has 1 planetary tower + 5 star towers!

In Wu Feng's territory, there are a total of 2 planetary towers + 10 star towers, and the increase in all attributes brought by the shining stars has reached 210%!

The mere existence of these planetary towers and star towers is enough to make the defense line invincible! Although there are many dark monsters crawling out of the sinkhole, in front of so many high-level defense towers, they are almost the same as those given away for nothing.

Starlight and Starlight continue to bombard enemies, Starlight's kill count continues to increase, and the Star Towers can grow rapidly.

"Both here and the Demon Canyon defense line must build the Titan City Wall, and the monsters here must not be allowed to escape!" Wu Feng also invested a lot of magic crystals and resources in the Tiankeng defense line to build the newly acquired Titan City Wall!

This is a legendary super wall, and it is simply the best choice for building a defensive line.

Titan City Wall Blueprint: Legendary quality, you can invest a lot of magic crystals and legendary resources to build the Titan City Wall, which can be used repeatedly, 500,000 magic crystals and 5 units of meteorite stones and 50 units of diamonds need to be invested in 1 km. 【Click to view detailed attributes】

The wall blueprint is one of the few architectural drawings that can be used repeatedly, and its construction price is settled in 1 kilometer, as long as there are enough magic crystals and resources, the Titan city wall can be built into a wall as long as the Great Wall.

It's just that at present, with Wu Feng's wealth and resources, he can only build a small amount of Titan City Walls in the Tiankeng Defense Line and the Demon Canyon Defense Line.

After all, this Titan City Wall requires 500,000 magic crystals, 5 units of meteorite stones, and 50 units of diamonds to be invested in 1 kilometer!

Wu Feng doesn't have too many resources of this legendary quality, and after raising them, he can only build about 10 kilometers first.

Wu Feng gave priority to the construction of the Titan City Wall of the Tiankeng Defense Line, because this city wall was too tall and majestic, and required a large number of craftsmen, Wu Feng also used the newly obtained designated craftsman card, and summoned 20 perfect quality construction masters.

Xiao Wang was also evolved to perfect quality by Wu Feng with the Craftsman Evolution Card, and was responsible for leading this group of construction grandmasters to build the Titan City Wall.

It takes 3 hours to build a 1-kilometer Titan City Wall, Wu Feng stared at the defense line, and after some hard work, the Titan City Wall finally took shape!

Titan Walls: Special building (Legendary quality), 2000 defense, durability: 5 million (1 km). The Titan Walls are over 100 kilometers long and will activate new effects.

Incidental skills: Titan Wall, Titan Power, Titan City Defense, Titan Guardian.

Titan Wall: The Titan Wall has a height of 100 meters, which can reduce the damage taken by the wall by 50%, and can protect the towers within the wall, increasing its defense by 100%, reducing the damage taken by 30%, and the Titan Wall can restore 10,000 durability points every 30 seconds.

Titan Power: Towers within 5 km of the Titan Wall will receive a large defense tile effect bonus, and every 1 km of the Titan Wall can provide a Titan Power bonus to a nearby tower within 10 km, which can increase its damage and range by 150%.

Titan City Defense: There are 10 trebuchets on every 1 km of the Titan wall, which can throw huge stones to deal damage to enemies at a range of up to 10 km, and the stones can be replaced with other projectiles. For each 1 km increase in the walls of Titan, the range of the trebuchet is increased by 2%.

Titan Ward: When Titan Ward is enabled, it reduces damage taken by 90% and increases durability regeneration by 500% for 30 minutes, and Titan Ward can be used up to once every 42 hours.

Notes: Titan Guardian was created by the craftsmen of the Titans and is known as a city that will never fall.

The Titan City Wall is much stronger than the previous steel city wall, and the super high defense and durability, the lord at this stage is almost unable to shake it.

That's the extent that even if the enemy attacks it, it can be restored by the self-repair of the Titan wall, and it can indeed be called an unfalling city.

If the walls near the Lord's Heart are all made up of Titan walls, then the attack of the Burning Eight Desolations and the Filling Mouth True Monarch is a complete joke!

"It's too late to build slowly, at least the Demon Canyon, the Tiankeng Defense Line, and the Lord's Heart Protective Inner City can all be built with the Titan City Wall, which are the three most important defense lines."

Even with Wu Feng's wealth, he only plans to build the Titan City Wall in these places first, and when he is richer in the future, he will fully roll out the construction of the Titan City Wall.

At this stage, the outer city wall is completely sufficient with steel walls.

After the construction of the 1 km Titan city wall, the increase brought by its radiation is very obvious, and the defense towers of the sinkhole defense line have been blessed with the equivalent of large defense plots, which is a 50% increase in all attributes, and you can also get meritorious deeds to improve the tower defense attributes.

This effect alone has skyrocketed the output capacity of many defense towers, especially the planetary towers, which have also received the full blessing of the power of the Titans, and the damage and range have been increased by an additional 150%!

This alone makes it extremely easy for the planetary tower to face underground monsters, and level 35 monsters are also just a matter of meeting in seconds!

At the same time, there happened to be an orange quality Hell Cryptman crawling out, this boss is very tall and mighty, but after he climbed out of the sinkhole, what he saw was the towering Titan wall!

"It's ...... A wall up to 100 meters high? How could there be such a tall wall here! "The people of the Hell Crypt are stunned, this city wall is built at the exit of the underground world, doesn't it completely block the access to the underground world.

In any case, the Hellburne's Cryptman can only attack the Titan Wall, but his attack is completely tickling in front of the Titan Wall.

Wu Feng didn't even need to send someone to repair the city wall, the self-healing ability of the Titan city wall was enough to restore durability, and Wu Feng only needed to make the defense tower go crazy.

As a result, the Planetary Towers and the 5 Star Towers all targeted the Hellcavemen, and hundreds of shining stars set the boss on fire at the same time.

After a round of attacks, the Hellburne's Cryptman was killed with half of his HP, and the orange boss looked so vulnerable.

In the second round of attacks, the orange boss was killed, and the falling orange crystal made Wu Feng wake up, with so many defense towers and Titan walls, it is impossible for the underground world to break through the defense line in a short period of time.

Wu Feng also built a connection point for the Goblin Post Station here, and his heroes and troops can support him at any time, and he can respond to any situation, and the defense line of the sinkhole is stable.

"Very good, then build another 5 kilometers of Titan City Wall, and while completely surrounding the sinkhole, you can let the Star Towers get the Titan Power bonus."

"The monster lairs in the underground world can be my source of resources!"
