The end of the world: My arrow tower has more than 100 million points

Although the number of zombies has been reduced a lot, the people Chu Ran sent out were too strong.

Regardless of whether they are divine archers or elf archers, half of the experience points they gain from killing monsters will be given to Chu Ran.

There are so many people helping to upgrade, and I can’t slow down even if I want to.

Especially the elf archers led by Shana were even more outrageous. Thanks to their ability to fly, Shana and this group of ladies actually ran to a distance of 50,000 meters. Most of today's experience was contributed by these ladies.

"One level per day, very stable. I hope nothing will happen before reaching level 20."

Chu Ran prayed silently in his heart.

When the level reaches level 20, the God of Architecture will awaken new skills.

Every time the God of Architecture awakens, Chu Ran becomes more powerful.

And after level 20, new buildings can also be unlocked in the territory.

Maybe Chu Ran's prayer had an effect. Since the zombies stopped, there has been no zombie riot.

Even during the day.

However, Chu Ran got the latest news from the military.

Zombies are indeed evolving, and the rate of evolution is not slow. They will condense elemental crystals in their skulls, and some powerful zombies can even condense enchantment stones.

This discovery made Chu Ran's eyes light up.

Elemental crystals and enchanting stones are all good things.

It would be great if zombies could be born.

After learning the news, Chu Ran told Shana and Li Guang to remember to take away the materials after killing the zombies.

However, the materials obtained did not satisfy Chu Ran.

Because Chu Ran discovered that the elemental crystals condensed in the zombies were only semi-finished products, which should be related to the fact that the zombies had not yet fully evolved.

However, two elemental crystals can also be compared to one, and you still need to collect what should be collected. As for the enchanted stone, Chu Ran did not find it.

On the fourth day, Chu Ran's level was raised to level 20.

"Ding, congratulations on raising the host's level to level 20. The God of Architecture has awakened his skills, and has been upgraded to level 1 beyond the limit."

Over-limit upgrade 1: You can ignore the building level and forcibly upgrade the building level. The current skill level can increase the building level by 1.

"So, can the nine-level arrow tower be upgraded to the tenth level? Can the luck tower and military aircraft pavilion be forcibly upgraded?"

Chu Ran's eyes widened, this was a bit strong.

Because the lottery is no longer available, the source channels of the Qi Luck Tower and the Military Machine Pavilion are no longer available, so it is cost-effective to use the over-limit upgrade now.

The most cost-effective thing is the arrow tower.

Upgrading the level of the arrow tower will double the attributes of the arrow tower. This improvement is not just one or two points. Take the thunder tower as an example. As long as it is upgraded by one level, the attack power of the thunder tower will instantly soar to more than 50,000. , if you add the bonus provided by luck value and knowing blow, then...

The picture was a bit cruel, and Chu Ran couldn't help but grin.

"Hey, don't worry, let's see what new buildings are unlocked."

Chu Ran's mentality is very beautiful. Even if the new building unlocked at level 20 is useless, it will not affect Chu Ran's mood at all.

However, after seeing the new building unlocked after leveling up to level 20, two big words appeared on Chu Ran's face: Damn it.

"How do you choose this?"

The level of the city lord's mansion has been increased to level 20, and there are two buildings unlocked, but you can only choose one of the two.

Research room.

Science and Technology Research Laboratory.

Myth Research Laboratory.

The two new buildings that appeared are also introduced in detail.

The Science and Technology Research Laboratory, science and technology orientation, can research and unlock various technological weapons after construction. The advantage is that the initial investment is small and the research speed is fast. The disadvantage is that later research will consume a lot of resources.

After all, Blue Star's technology is pretty good, and here's the foundation.

The Myth Research Laboratory, Myth Direction, can research and unlock various mythical weapons after its construction. The advantage is that the single attack is powerful, but the disadvantage is that it requires a large amount of resources in both the early and late stages.

Chu Ran was a little confused.

This is really confusing.

Others may not understand the power of myth, but Chu Ran understands it.

Shana is a mythical hero. If you put the word "myth" in it, there is no one who is weak.

If Chu Ran had time and resources, he would definitely choose the Myth Research Laboratory without any scruples.

But does Chu Ran have time now?

The most important thing is, are there the resources?

The research on science and technology from mythology is definitely not just something that can be done using a little bit of wood, iron, and stone.

The most basic research materials have to be things like elemental crystals and reinforced stones, right?

"No time, no resources, no choice at all."

Chu Ran shook his head and sighed.

I am still too weak.

Don't think Chu Ran is foolproof just because he has built a large number of arrow towers.

The previous zombies were too weak.

Today's zombies are getting stronger every day. This is the information Shana and the others got after killing zombies every day.

The point is, the number of zombies is too huge.

There is no need for millions of zombies to attack. As long as hundreds of thousands of zombies swarm in and attack Chu Ran's territory, even Chu Ran's current territory's defense strength will not be able to withstand it.

The arrow tower outside the city will be bulldozed as soon as possible.

The main city couldn't hold on for long.

Therefore, Chu Ran had no time to waste on research.

Why does Chu Ran keep going out to build arrow towers every day?

Isn't he afraid that zombies will destroy his main city?

"I choose the Science and Technology Research Laboratory."

Chu Ran made the choice reluctantly.

However, Chu Ran is not too disappointed. The technology in the later stage should also be very powerful, because the introduction said that technology research in the later stage also requires massive resources. Maybe the technology will far exceed the current level of Blue Star.

"Build a science and technology research laboratory."

After making his choice, Chu Ran ordered the farmers to start construction.

The construction of the research laboratory consumes very little wood and not much stone. The main consumption is iron.

Fortunately, there are iron mines near Chu Ran's territory, otherwise it would really be unaffordable.

"It seems that we need to let the farmers collect more iron materials."

Modern technological weapons do not use wood or stone. In the future, the bulk of resource consumption will definitely be iron.

"It actually takes one day to build the laboratory. It's really slow. If the time hadn't been shortened, wouldn't it have taken ten days?"

Chu Ran said that he couldn't wait.

After instructing Old Man Zhang to arrange for people to collect a large amount of iron materials, Chu Ran continued to take people out to build the tower.

However, Chu Ran is not planning to expand the territory outwards. He wants to make the arrow towers outside the main city denser.

Intense fire coverage can effectively kill groups of zombies.

One day later, the three-story science and technology research laboratory with a single floor area of ​​more than 500 square meters was successfully completed.

As soon as the research room was built, Chu Ran couldn't wait to rush in.

"No one?" Chu Ran looked around after entering the research room. There was no one in the research room. Everything was full of technology. Looking around, there was a metallic luster everywhere.

"Master is welcome to enter the research room. Please read the research room function manual carefully."

"Shana? Why are you here?"
