This is a quality developed through years of practice.
But the sea beasts in front of them had expressions of surprise and ridicule on their faces.
Most of those who can participate in the siege battle are great demon kings from various places. They already have enough intelligence to understand human speech.
After hearing Lu Yu's words, they subconsciously thought that Lu Yu was afraid.
"Roar! Fight in! Eat all the humans inside!"
All the sea beasts present roared excitedly and attacked even more fiercely.
The defenders present could even see the sharp teeth of those sea beasts at close range, as well as the smell of blood coming from their mouths.
Many people's faces suddenly turned pale.
If they fall into the hands of these sea beasts, they will be chewed alive and then swallowed. The pain experienced before death will be unforgettable for anyone.
Leng Wuxiang was already ready to fight when he suddenly heard Lu Yu's voice. He turned around and said in astonishment: "Sir, why are you retreating when you are doing well?"
Not only him, but also many generals present did not understand.
They had always adhered to the orders they had received before.
Moreover, these monster beasts are attacking so fiercely now. If we relax a little, a vacuum area will be left on the city wall. At that time, those monster beasts will take the opportunity to rush up.
Lu Yu did not explain.
He and I suddenly took a step forward and walked towards the direction where all the sea beasts were charging.
In front of him, those sea beasts took advantage of the retreat of Dayu's army and had already found the opportunity to climb onto the city wall.
Huge monster heads were suddenly revealed in front of everyone.
The eyes of these monster beasts are all bloody red, and there is no emotion in them. All the humans in the Tianchong Pass are nothing more than food for them.
The solemn smell of blood is already so close that you can feel it.
"It's over!" Many soldiers had closed their eyes in despair.
By retreating like this, they had already given these sea beasts a chance.
It may still be difficult for those sea beasts to climb onto the city wall, but now that they have climbed up, they are confident.
However, next, everyone on the entire city wall saw a scene that they would never forget!
The purple flame that had been beating in Lu Yu's eyes finally flew out.
Two balls of purple flames flew forward.
There were several ferocious monsters, and when they saw these two insignificant flames, a look of contempt suddenly appeared on their faces.
They stretched out their sharp claws and grabbed at the purple flames in front of them.
But almost instantly, the purple flames suddenly emitted a strong light, and then, the flames suddenly enlarged, and the endless sea of fire covered all directions in an instant, drowning all the sea beasts.
The group of sea beasts that rushed over, one after another, let out shrill screams in the purple flames.
The purple flame spread in all directions, and everything within a kilometer away from the city wall was plunged into a sea of fire!
The flames are raging into the sky and black smoke is rising!
The raging purple flames burned, and the high temperature generated caused even layers of ripples visible to the naked eye to appear in the surrounding void.
Those monster beasts were originally rough-skinned and thick-flesh, able to withstand the erosion of fire.
However, under the burning of the purple flames, all the sea beasts screamed and retreated, and some were even burned to ashes on the spot!
