Chapter 536：

If you want to match it, it is impossible.

And right now.

Lu Yu's eyes shone with a cold light.

The army was slowly advancing, when it came to the bottom of the city.

Look at the stern barbarian.

There was a look of disdain in his eyes, do you want to rely on shrinking troops to resist your attack?

It's simply self-defeating.

After thinking of this, he opened his mouth to the people around him.

"Thunder cannon, smash the city wall!"

Just when his voice fell.

"Boom!"

The huge thunder cannon, at this time, burst into the thunder of destruction in an instant.

Blast towards the top of the city.

The sound like a thunderbolt kept ringing at this time.

With destructive energy.

The city wall in front was directly covered at this time.

"boom!"

A wall was directly shattered at this time.

Then I saw that the flying stones above the city head splashed.

When it falls on the people around you.

Although the physical bodies of those barbarians are strong, they cannot resist such an attack.

It was pierced in an instant.

Screaming out of his mouth, he died on the battlefield.

And such a scene has only just begun.

The thunder artillery attack almost never stopped.

The barbarian's feather arrows met this devastating artillery fire.

It's just an egg on a rock.

Before the feather arrow fell, the thunderbolt flew out and shattered it instantly.

Above the city head, there were bursts of roars and roars.

Everyone doesn't want to die.

They want to live.

But under such an attack, survival is an extravagant hope for them.

At this time, Lu Yu didn't pay attention to this.

In his mind, the sound of the system sounded.

"Ding, does the host sign in at the Elite Crown Battlefield?"

"Sign in!"

Without the slightest hesitation, Lu Yu spoke directly.

"Ding, congratulations to the host, you have obtained 50 billion spirit stones!"

After the sound of the voice, a smile appeared on Lu Yu's face.

This system is really sweet.

Knowing that he lacked spiritual stones, he sent 50 billion directly, and so on.

Attacking barbarians should be no problem.

After all, whether it is a thunder cannon or a divine light cannon, a large amount of spiritual stones are needed as energy.

Now, it's fine.

And at this time.

Cao Zhengchun walked over cautiously.

After seeing Lu Yu, he said respectfully.

"Your Majesty, General Yue Fei said that we are running out of spirit stones, should we continue to attack now!"

There was a hint of questioning in his voice.

After all, the current city wall has not been completely broken, if the army is allowed to attack.

There must be losses.

After hearing the sound, Lu Yu's eyes flashed with cold light.

Put a space ring in Cao Zhengchun's hand.

Then said slowly.

"There are some spirit stones in here.

Give me the first one billion hits! "

When his voice sounded, Cao Zhengchun didn't dare to hesitate, and hurriedly walked forward.

In a short while, the Thunder Cannon, which was still somewhat sparse, became extremely violent in an instant.

Even in the sky, they converged into thunderclouds.

It didn't stop until a few hours later.
