Doomsday Superhero Summoning System

Such a high-intensity battle lasted for seven days. During these seven days, everyone in the base witnessed how Zhou Yan fought. They saw that Zhou Yan fought so hard to protect their base. Each and every one of them attacked Zhou Yan.

I had great admiration.

Although they didn't know why Zhou Yan was working so hard, they knew that if it weren't for people like Zhou Yan, they would have probably invaded the Yangcheng base by zombies within the next seven days.

Zhou Yan and others were so powerful, and from the beginning to now, not even a single person was lost, not to mention no loss, not even injured, which made them really confused.

Zhou Yan himself digested a lot, with blue medicine being the first, followed by various props. He had used up all the large-scale magic scrolls he had drawn in previous draws, and the results were quite satisfactory.

Every time he flew into the air and threw it down where there were many bosses. Although he did not kill the zombie king, he killed many spiritual zombies. Such zombies are usually very difficult to find.

.

This time, he was given several rewards, which made him very happy. These were all hidden tasks. Every spiritual zombie was very rare and precious.

This week, his level has soared again. It is already level 79, which is very close to level 80. He still did not use the eight times experience card because the boss has not appeared yet.

He only had this eight-fold card left in his hand, and all the others had been used up. Otherwise, he would not have reached level 80 so quickly. The further back he goes, the more terrifying the experience value becomes.

Although there were still dense zombies around him, he didn't care at all.

Anyway, no matter how many zombies there are, it is useless. Instead, they are the experience for him to upgrade and the way to obtain gold coins. Over the past few days, the total number of his heroes has reached 90.

If a lot of gold coins were not needed to buy blue medicine, the quantity would probably be even greater. Secondly, the harvested materials are countless.

On the eighth day, the zombies besieging the Yangcheng base changed and began to turn into high-level zombies. The number was reduced a lot. Soon he received a message from the hero, saying that the zombie king had been found.

"Oh, it finally appeared." He did not take action immediately, but asked the heroes to pay attention to its movements and not let the boss escape.

According to the news passed back by the heroes, there are many powerful boss guards around the boss. Unfortunately, he has run out of scrolls, otherwise he would really be able to get one for him.

The four city walls are all attacked by the same zombies. There is not a single ordinary zombie, all are advanced zombies such as evolved zombies and mutant zombies. Their levels are all above level 50, and there are even many bosses from bronze to gold levels.

It seemed that the boss had to defeat Yangcheng at once. If he hadn't appeared, there would be no need to use such a method. Unfortunately, when the boss encountered him, he was destined to be able to draw water from a bamboo basket.

There are still a lot of zombies, but the zombie emperor has lost his patience, otherwise he would not have discovered their existence so quickly.

"roar!"

The zombies began to attack. The speed, strength, and destructive power of these zombies were not comparable to those before. They were all very powerful, but there were not as many as ordinary zombies.
