Binding Luck: Begin as Qinglian Sword Immortal

Chapter 30 Upgrading the City, Flying Monsters
[Do you want to upgrade the city? 】

[After the city is upgraded to the second level, a new defensive building - anti-aircraft tower will be unlocked, the defense power of the city wall will increase by 50%, and the attack power of the defense tower will increase by 20%!Reduce the launch interval by 50%! 】

Two options popped up in front of Lu Bai.

"upgrade!"

Lu Bai made a decisive decision.

Swish!
The city behind Lu Bai flashed a light.

The dazzling light made people unable to open their eyes at all, and the monsters outside the city were also screaming.

The little cute dragon behind Lu Bai buried his head on Lu Bai's shoulder.

When Lu Bai opened his eyes again, he could see clearly.

The city walls of the city are half as high as before, and much thicker.

The defensive towers standing on the city wall are more textured than before.

[Announcement: Datang player Lu Bai took the lead in upgrading the city to the second level, and was rewarded with a mysterious treasure box, points + 10000, gold coins + 10000! 】

[Announcement: Datang player Lu Bai, first upgrade the city to the second level, Datang will receive the blessing of the gods, and the defense power of all cities will be doubled! 】

……

"how is this possible?"

The repeated beeps made Tuoba Hong a little unresponsive.

How could this be?
How did you upgrade the city?
How long has it been? Can Lu Bai hold on?

Can you upgrade the city in turn?
It shouldn't be!

The development of the matter has gone beyond Tuoba Hong's comprehension.

"Prince, what should we do now?"

"That Tang man is too good at defense, right?"

"I just looked at it, upgrading the city requires 1000 million gold coins, my God!"

"If he really keeps it? Don't we just lose our wife and lose our army? Isn't it a big loss?"

The dozen or so people under him were discussing in one go.

Some people have already begun to express regret.

This made Tuoba Hong very uncomfortable.

"What's the rush? How long has it been? It's still early. I don't believe he can really hold it. Let's wait for the third wave of monsters to come and get the third wave of rewards first!"

"The prince is right!"

"We are all grasshoppers on the same rope. We all prosper, and we all lose!"

"That's right!"

……

At this moment, Lu Bai felt more balanced.

Tuoba Hong was equivalent to taking away his first kill and sending him a first kill.

Lu Bai suddenly felt that he was doing it again.

Just when his self-confidence was extremely inflated.

The beep sounds again.

[Note: Flying monsters are about to participate in the siege!When the flying monster reaches the central airspace of the city, it is regarded as entering the city! 】

Flying monster?

Lu Bai raised his eyebrows.

This is the first time it has appeared.

On the small map, a yellow frame appeared in the center of the city.

This should represent the central airspace.

Compared with land monsters, flying monsters are much more difficult to defend against.

When land monsters enter the city, they all target the city gate, so they can focus on defending the city gate.

But flying monsters can freely choose routes in the sky.

This is where it gets tricky.

Lu Bai opened the system mall.

Sure enough, there was an additional option for an anti-aircraft tower in the defensive building.

The construction of anti-aircraft towers is twice as long as that of defense towers of the same level, and the construction time is about the same.

As soon as Lu Bai got started, he built twenty ground-level one-star air defense towers at the same time.

At the same time, he himself also controlled the Qinglian sword, flying high in the air.

Before the defense tower was built, he had to resist the attack of flying monsters alone, and he had to take care of the monsters that the defense tower could not deal with on the ground.

Swish!
The mini-map was refreshed again, and more than a dozen blue light spots suddenly appeared on the map.

This should be where the flying monster is represented.

Lu Bai looked in that direction, and saw more than a dozen black spots appeared in the distant sky.

These black dots are growing rapidly, very fast, much faster than land monsters.

At this speed, it takes at most two to three minutes to break into the central airspace.

This did not leave much time for Lu Bai to react.

It was only when the monster got closer that Lu Bai could see it clearly.

There are fifteen monsters in total, with the head of a lion and the body of a lion, with wings on their backs and four eagle claws.

Lu Bai drew the "Bow of Chasing the Sun", aimed at the front end first, and let go of the bowstring resolutely.

Ode~
A light arrow was launched.

Lu Bai didn't wait to see whether the light arrow hit or not, and then shot out another arrow.

At this moment, the first light arrow just happened to hit the first monster.

[Successfully kill the Gryphon (earth-level two-star), get points +2600, gold coins +2400! 】

In less than ten seconds, Lu Bai shot more than ten light arrows in a row.

All a dozen Gryphons were shot down.

[Successfully kill the Gryphon (Xuan-level nine-star), get points +1170, gold coins +1080! 】

[Successfully kill the Gryphon (Xuan-level eight-star), get points +1040, gold coins +960! 】

【…】

Immediately afterwards, more blue light spots appeared on the small map again, coming from two directions.

This wave of flying monsters is twice as many as before.

Lu Bai ran around, and had to take care of the monsters on the ground, so he was in a hurry for a while.

At first, Lu Bai was still able to persevere.

After three waves, flying monsters surrounded him from all sides, and Lu Bai was struggling a bit.

Swish!
A flash of arrows shot down the last monster of the fourth wave.

As soon as Lu Bai lowered his head, he saw a heaven-level monster approaching the city gate.

The arrow light from the sky-level defense tower landed on the monster, but only burned a piece of it on the back.

After the monster screamed, it continued to charge forward.

Seeing, the monster was about to break through the city gate.

"roar~"

A cute and cute roar erupted from behind Lu Bai.

It's not loud, but full of momentum.

The day-level monster that was directly shocked froze.

In just this instant, Lu Bai's light arrow arrived in front of the monster.

The arrow of light sank into the monster's body.

boom!
The monster's body exploded.

[Successfully kill the Frost Mammoth (five-star heaven), get points + 65000, gold coins + 60000! 】

[The anti-aircraft tower has been built! 】

Call ~
Lu Bai could breathe a sigh of relief.

【Air Defense Tower (Earth Level One Star)】

[Range: 20 zhang, the power is equivalent to the strongest blow of an earth-level one-star monster (+50%), fired once every three seconds (-[-]%)! 】

Lu Bai quickly arranged twenty air defense towers around the central airspace.

At this time, the fifth wave of flying monsters appeared.

The number is at least eighty or ninety.

The minimap is painted blue.

In just 30 seconds, the flying monster entered the attack range of the air defense tower.

Ode~
Twenty defense towers released light arrows at the same time.

In an instant, more than a dozen monsters were hit and exploded in the air.

The leading monsters with one star and above the prefecture level were followed by Lu Bai and named them one by one.

This time, the flying monster was cleaned up in just over 20 seconds.

The efficiency is several times higher than that of Lu Bai defending alone.

However, Lu Bai still could not neglect.

Hurry up and continue to upgrade defense towers and anti-aircraft towers.

I believe that after experiencing this beast tide, the city of Datang can truly become a city that will never fall.

Such a density of monsters can be carried through, what could be more exciting than this?
Just like that, Lu Bai lasted for another hour!

[The third wave of monster siege begins! 】

　It’s getting late and late, and the next one will be tighter, and I will try to release it before twelve o’clock. Now I have to write a little slower. If you have any questions about the plot, you can post a chapter and leave a message, or join the group to discuss, thank you!
