Chapter 49: All defense towers upgraded to level 4

See the length of the first-level spear in his hand.
Qiao Shan knew that this spear would be easy to sell.
Because it's long enough.
At least two meters in length...
Long means safe.
Being long also means you can attack earlier.
After the delicious plums, Qiao Shan realized that he had a new flagship product to sell - the black spear.
Throw the "dark spear" into the package and plan to hang it up later.
Qiao Shan quickly realized that the price of iron ore in the [trade] should be more expensive.
As more and more equipment crafting diagrams are revealed.
Almost all low-level equipment requires raw materials such as iron ore.
The price of iron ore will inevitably rise.
A huge increase.
There are not many ways to produce iron ore at present.
In addition to the rewards for clearing a level, ore packs will occasionally be opened.
There is only one accessory called "Skeleton Miner" that can be used to mine ore.

Moreover, with the rising price of iron ore.
The sporadic "Skeleton Miner" transactions also disappeared.
"Wait and see if we can get a pair of skeleton miners back!"
Iron ore prices are going to rise sharply, and Qiaoshan also wants to make some preparations.
Of course he knew that the "Skeleton Miner" could not be bought.
But if there are good things, it is possible to exchange a few of them back.
"continue!"
After thinking about the spear and iron ore, Qiao Shan looked at the next reward taken out from the Tower of Babel.
Not finished watching yet!
no way.
There are so many rewards to be gained.
In a game of Tower of Babel, others only gained single-digit experience and silver coins.
He got a lot of stuff straight away that he had to look through for a long time...
Do you think it is hateful or not?
provoke,
It's so annoying.
So be anonymous, hide.
"Defense tower unlimited upgrade scrolls x 5".
The next thing Qiao Shan checked was what he was most looking forward to.
The fourth-level defense tower has unlimited upgrade scrolls, and 5 of them come directly.
Qiao Shan understood that this scroll should be a reward for a critical hit.
Because the reward is so good.
All of them are invincible, 5 at a time.
I can only say that the European emperor is alive, and the critical hit is beautiful...
5 unlimited upgrade scrolls solved Qiao Shan’s biggest worry.
Special tower!
A special tower that can only be opened over and over again by opening the blueprint.
It is difficult to encounter the same ones, so you can upgrade the tower together.
Most of Qiaoshan’s special towers were purchased.
He was unlucky and couldn't open a special tower...
He was originally
The monsters are also increasing in strength.
The first-order special towers will become increasingly useless.
Unexpectedly, there was a wave of critical hit rewards from the Tower of Babel.
This directly gave him the opportunity to upgrade his special tower.
Wuhu~
take off!
Picking up a scroll, Qiao Shan walked out of the thatched hut and came to his own defense tower.
Because of the existence of goblin craftsmen.
All of his defense towers currently have full durability.
Furthermore, goblin craftsmen seem to have special abilities.
The durability of the defense tower after they repaired it was even higher than before.
On average, it can increase by 30%...
There was no time to admire the skills of the goblin craftsmen.
Qiao Shan slammed the torn upgrade scroll directly onto a defense tower in front of him.

“Wow~”
The scroll was close to his body, and the defense tower in front of him suddenly lit up.
A ray of light enveloped the defense tower he photographed.
Fire element wooden arrow tower!
The fire-attribute defense tower that Qiao Shan initially created using the scroll blessed by the fire element is now at the second level.
Johnson was the first to choose to upgrade it.
He had determined that his surroundings were a forest.
The rocket tower has very strong attack power in a forest environment.
The second-level Fire Element Wooden Arrow Tower cannot be upgraded using an ordinary Wooden Arrow Tower.
Qiao Shan chose to upgrade it using an upgrade scroll.
As the light faded, this second-order fire element defense tower, which had performed such a great service, underwent a drastic change.
The volume reached four or five meters high.
The bottom of the tower is nearly two meters in diameter.
Lines of burning flames were engraved around the defense tower.
Even the surrounding environment became much brighter.
A fourth-order fire element wooden arrow tower that looks like a visitor from hell.
Appeared in front of Qiao Shan.
His eyes lit up and his brows raised, and Qiao Shan opened the attribute column of the fourth-order fire element wooden arrow tower.
【Fire Element Wooden Arrow Tower
Level: Level 4
Range: 400 meters
Attack speed: 1 second/time
Attack: Double arrows, attack power 80-150 (can defend against air attacks)
Rapid Fire: Attack speed increased to 0.5 seconds/time, duration 1 minute, cooldown time 10 minutes.
Elemental Blessing: Each arrow adds fire element attack, increasing attack power by 20 points, and can form a flame attack on the corresponding monster.
PS: Continue to upgrade, there are big changes...
As expected, the fourth-level Fire Element Wooden Arrow Tower also has double shooting and air defense capabilities.
Not only has the attack power increased several times.
Moreover, the attack power enhanced by the fire element has been increased to 20 points.
Of course, if [prompt sound] is used to lure Qiao Shan and continue to upgrade the defense tower to level five, it will still exist.
pity…. ,
This special tower is too troublesome to upgrade.
To upgrade to level five, it seems that you need to obtain the level five "Defense Tower Unlimited Upgrade Scroll".
If you are unlucky, you may have to wait until the year of the monkey and the month of the horse.
"Next!"
However, I didn't worry about the fifth level.
The fourth level is enough for now, so Qiao Shan chooses to continue upgrading other towers.
Soon, he got a special tower of the fourth level.
【Vine Tower

Level: Fourth level
Category: Special Tower
Range: 400 meters
Effect: Sends out a powerful vine that binds a monster for 10 seconds (no decay).
Double Pull: Send out two vines at a time.
Pull back: Tie up a monster and pull it back 100 meters, once a minute.
PS: Controlling two at a time is called double control.
The second scroll was used by Qiao Shan on the vine tower.
This is the defense tower he built specifically to pass the boss level.
With the help of the scroll, it directly changed from level one to level four.
Compared to the first-level and fourth-level vine towers, the attack distance and binding time have been greatly improved.
The biggest change is that it can send out two vines at a time.
Let's have a double bang.
On the fourth-tier vine tower, there were two dark vines as thick as thighs.
There was still a green glow on the vines.
Glowing faintly.
Without testing its ability, Qiao Shan quickly tore open the third scroll.
With a flash of light, another special tower was upgraded to the fourth level.
Poison Mist Tower
Level: Level 4
Range: 400 meters
Poison mist range: 50 meters
Damage: 10/second
Poison Mist Attack: Releases a poisonous mist to attack monsters within the range of the poisonous mist. The duration is 20 seconds (once every minute).
Weakness attack: The poison mist can automatically find the monster's weakness and corrode it with poison mist.
PS: You will die if you go in.
The fourth-level poison fog tower is the best choice for reducing blood.
No matter what type of monster it is, be it land, sea or air.
The debuff damage of poison fog is always very strong.
And the longer the time, the greater the damage.
Poison tower!
A very special kind of defense tower.
At this moment, the first-level poison fog tower was upgraded to the fourth level by Qiao Shan.
Inside the fourth-tier tower, a transparent container that looked like a poison jar appeared.
There was green mist inside, which looked very creepy.
"We need to find an opportunity to move this tower..."
The appearance of the poisonous fog tower made Qiao Shan decide to find an opportunity to move the tower farther away.
It looks too dangerous.
This kind of dangerous thing must be kept away from residential areas.
If something goes wrong, it will be a big trouble...
