Doomsday Superhero Summoning System

In other words, a first-level crystal core can bring some upgrade energy to the defense tower.

Zhou Yan released several more, but found that this was not the case. The energy of these energy crystal nuclei was divided according to the monster level. The mass difference between the crystal nuclei exploded by a level 1 monster and a level 10 monster was 9.

Zhou Yan filled up the upgrade energy of the defense tower and spent hundreds of crystal cores.

System: "The defense tower has been upgraded to Level 2, and all attributes have been improved."

Item: Defense Tower

Level:2

Upgrade energy: 2/4000

Attribute: Defense value 20000

Attack distance: 12 meters

The upgrade energy doubled, the defense value also doubled, and the attack distance increased by 2 meters. Zhou Yan filled in all the remaining crystal cores and took out the second-order crystal cores he had harvested.

Only then did he successfully upgrade the defense tower to level 3.

Sure enough, the upgrade energy changed from 4000 to 6000, the defense value increased by 10000 again, and the attack distance also increased by 2 meters. Now it can attack enemies beyond 14 meters.

Not long after, the zombies came to the attack range, and the defense tower began to attack quickly, sending out two beams of energy to attack the monster.

The two zombies were immediately exploded by the attack from the defense tower. The entire body world was exploded and torn apart. Not to mention how violent it was, Zhou Yan bought four Death Caps of the World Destroyer.

This is the role of equipment. Luana's hurricane skill has the ability to attack two targets at the same time, and can also be used on defense towers. This proves that his idea is correct.

Not only that, even the magic lightning attached to the electric knife is also useful on the defense tower. The defense tower cannot move, but it can naturally be charged. Each attack can charge 2 points, and it only needs to be attacked fifty times to recharge.

Success, although it charges slower than when heroes move, it is still a powerful piece of equipment.

But Sivir stared blankly for two seconds again, and quickly reacted. While attacking, he asked Zhou Yan: "This defense tower can actually wear equipment. Isn't it too strong?"

"Yeah, I didn't expect that the defense tower would attack so fiercely after putting on the equipment. It was really beyond my expectation." Zhou Yan was also very surprised.

The only disadvantage is that it can only attack alone and does not have the ability to attack as a whole. If it can cover a large area like a giant cannon, there is no need to be afraid of these zombies no matter how many there are.

"It can only stay here and cannot move except by summoning it back and summoning it back again." Zhou Yan pointed out the shortcomings.

"You still want it to move, your demands are too high." Sivir rolled his eyes at Zhou Yan and said angrily.

Zhou Yan touched his head and said: "The attack speed is pretty good. I found that it would be more appropriate to buy an additional piece of equipment to increase the attack speed for the defense tower." He didn't expect the attack of the defense tower to be so powerful. If he had known better, he wouldn't have bought it.

Multiple pieces of the Deathcap of the Worldbreaker.

"What equipment did you buy?" Sivir asked curiously.

Zhou Yan told Sivir about the purchased equipment, and was immediately scolded: "What a waste, what a waste, what a waste."

Zhou Yan looked at Sivir, waiting to be disappointed. She said, "Buy the Fang of Nash. You didn't buy this piece of equipment that increases attack speed by 50% and increases spell power by 80 points. Instead, you bought four pieces of the World Destroyer."

Death Cap, what do you think?"
