Doomsday Superhero Summoning System

Ashe's experience value is only 20% less than his. There is still plenty of time now. It is only a matter of time before Ashe upgrades to level 3.

Zhou Yan now encountered a little trouble. Several elite monsters rushed to the front, two level 3 and one level 2. Under the leadership of these three elite zombies, Zhou Yan began to retreat faster.

.

"Ashe, kill these three elite monsters first." Ashe would only randomly attack zombies without his instructions.

He couldn't resist these three elite monsters now, so he could only ask Ai Xi to help. Ai Xi took action, which was naturally extraordinary. The first arrow killed the level 2 elite instantly.

"Good job, Ashe." This is what the long-range hero is good at. He also wants a bow. There is one in the store, but he can't afford it yet.

Ashe continued to attack the zombies. The first bow and arrow hit the elite monster, but did not kill it. Ashe attacked again, this time hitting the zombie's mouth, and penetrated directly from the zombie's roaring mouth.

, instant kill.

Finally, the last zombie was left, and Zhou Yan's pressure was greatly reduced. He was not a tank. If the cloth armor hadn't withstood a lot of damage, he would have retreated long ago. When the last elite was killed, they once again

Run upstairs.

System: "Your summoned hero, Ashe, has been upgraded and is currently level 3."

When they arrived on the eighth floor, Ai Xi emitted a blue light, and Ai Xi upgraded again. Ai Xi finally reached level 3.

He quickly upgraded Ai Xi's Thousand Arrows Salvo skill to level 2, which made Ai Xi's skill even more powerful. Ai Xi's status was at full capacity. With one move, Ten Thousand Arrows Volley, seven sharp arrows instantly shot towards

Zombies attack.

The sharp arrows were more powerful and colder than before. The moment they burst out of the air, they instantly penetrated the zombies downstairs. Two of the sharp arrows even managed to kill two birds with one stone!

"So powerful!" Zhou Yan was pleasantly surprised. He didn't expect that after Ai Xi's skills were upgraded, he would have such a powerful power. This was something Zhou Yan didn't expect.

After Ashe upgrades to level 3, the time she can appear finally becomes 40 minutes, so Ashe can kill more monsters.

Whether it is attack power or attack speed, Ashe has been greatly improved. Zhou Yan did not have time to observe Ashe's changes after upgrading, otherwise he would have been surprised, because Ashe's expressions were richer.

Facing these zombies, she frowned, as if she was disgusted. She did not stop the attack in her hand, and attacked the zombies with arrow after arrow.

Upgrading from level 3 to level 4 requires a lot of zombies based on 400 experience points. Zhou Yan didn't know if he could upgrade again today. He didn't know how many zombies came here.

They have now reached the 15th floor, and the zombies behind them don't seem to be so dense anymore. At least Zhou Yan and Ai Xi don't need to retreat as quickly as they did in the front.

After they killed a wave of zombies, they took the initiative to retreat. The zombies behind them would follow anyway, so they wouldn't block the zombies' progress.

After more than ten minutes, Zhou Yan finally heard the system prompt.

System: "The mission of killing 200 level 2 zombies is completed, and the reward is a dagger."
