Sitting there in a daze, Zhao Sheng didn't see the old man he had saved. At that critical moment, his right hand was tightly held at his waist and his muscles were tight.

In other words, even if Zhao Sheng didn't make any action at that time, the big dog couldn't do anything about him. However, Zhao Sheng moved, completely ignoring the cultivation gap between himself and the big dog.

Seeing what happened, the old man nodded happily.

Holding the green dragon spear, Zhao Sheng stood up slightly trembling.

Rivers and mountains are easy to change, but nature is hard to change. Even if Zhao Sheng said how many times he didn't want to be a good man, he couldn't control his instinctive behavior in an emergency.

"Thank you." the old man looked at Zhao Sheng and patted him on the shoulder.

Zhao Sheng nodded slightly.

"Zhao Sheng, right? You and your brother are responsible for the safety of the left side of our team. I'm responsible for the threats from the front. Xiao Yang is responsible for the right side and Xiao Liu is responsible for the back. You must be vigilant. Monsters may come out everywhere on the wall!" the old man said with a long mace from his waist and a trace of killing intention in his eyes.

"I see!" Zhao Sheng and four others answered at the same time.

Three hundred guards spread out five hundred self-organized teams on the wall.

When Zhao Sheng stood still, he suddenly found something surprising. That is, from the time they went up to the city wall to the time when the 500 teams spread out on the city wall, it was less than two cups of tea, and a full number of four or five hundred people were damaged on the city wall!

"Coming." the old man stared at the movement under the wall. When he grasped the long mace with both hands, the green veins on his hands burst in an instant.

A new wave of monster offensive was launched again.

And the big eyes look, in this group of monsters, there are a full half of the congenital monsters!

Everyone on the wall trembled when they saw this scene.

Many people want to escape and don't want to guard the city here. But what is very helpless is that behind them is the escort in charge of supervising the war. If anyone wants to escape, there must be several more transparent holes in his body.

"If only... Could burn the corpses of those monsters piled up as high as the city wall." Zhao Sheng, who was ready with a long gun, couldn't help whispering.

Destroy the "long ladder", not to mention reducing casualties, at least the rate of casualties will be much lower.

"It's hard to destroy..." said the man with "Yang Ying" embroidered on his robe. "These monsters are refined. Unless there is oil, it's absolutely impossible to burn them to ashes."

Yes, these monsters acting as "long ladders" are difficult to destroy... This... Is also the main reason why humans are often not opponents of monsters under the condition of equal cultivation.

Refining body is really strong.

The huge number of monsters is getting closer and closer to the "long ladder" in front of the city wall.

"Put the arrow!" a leader on the wall waved his flag forward, and the sharp arrows from countless strong bows went straight towards the monsters.

"Whoosh!" "whoosh!" "whoosh!" "whoosh!"

The sound of sharp arrows breaking through the air was clearly heard by everyone. These sharp arrows are very powerful. They can easily penetrate the skin when they come into contact with ordinary monsters.

But when these sharp arrows came into contact with those inborn demons, and everyone's breathing was stagnant, the sharp arrows stopped. Then he fell powerlessly to the ground.

It's easy to shoot two sharp arrows with transparent holes at the people present, which can't play a role in these congenital demons.

"Shoot the arrow!" the commander continued to wave the flag.

But before these arrows left the bow, a long roar of evil beasts came from somewhere outside the city.

"Ao ang ~"

Following this roar, a scene that stunned the people on the city wall appeared.

All the monsters stopped together, and then the congenital big demon blocked directly in front of the little demon the day after tomorrow. Unexpectedly, he connected the sharp arrows with his body.

"Shoot an arrow! Shoot an arrow! Shoot an arrow for me!" the commander was obviously a little impatient and couldn't stop yelling. But when he saw that those people holding bows and arrows didn't follow his orders to shoot an arrow, he couldn't help turning his head and wanted to yell.

But the moment the commander turned his head and roared.

"Whoosh!" a sharp arrow sounded louder than before. But this sharp arrow did not shoot from the city wall to the bottom of the city wall!

"Pooh!" the commander holding the flag kept the posture of turning his head. His eyes showed an incredible expression. He fell to the ground with a sharp arrow running through the temples on both sides.

The morale of thousands of people on the city wall fell to the freezing point at this moment!

"Long ladder" can't be destroyed. Sharp arrows can't even hurt the skin of monsters. Can their weapons pierce the skin of congenital monsters?

Can you hold Qingyan city? No one knows the answer.

"Alert! All God alert!"

Fortunately, soon, another man dressed very similar to the previous commander picked up the command flag and stood in the command position again.

At this time, there must be no chaos. Once it is chaotic, the west wall of Qingyan city will be broken. At that time, the whole city will die without a place to bury!

"Here comes oil and boiling water! Here comes oil and boiling water!"

When Zhao Sheng and others were ready to face the monster from this wave of impact, without any sign, a very happy voice came from the bottom of the city.

Oil, easy to understand. With oil, those "long ladders" have a high probability of being destroyed.

What is boiling water? Boiled water? Of course not.

So, what would it be? It's actually very simple. The real boiling water is the excreta accumulated by human beings in the city and the mixture of all kinds of swill!

This kind of thing looks disgusting and smells very bad, but once it boils, it can definitely be called a city guarding relic that can be destroyed at the touch of it!

There are reserves of fuel oil and boiling water in Qingyan City, but this kind of thing is extremely difficult to preserve, so the stock is not very much. And those things that were not much had already been used up in the first wave of battle to defend the city.

This situation directly led to the tragic casualties caused by the sudden emergence of the congenital demon.

"The captain of the twelve detachment obeys orders! The twelve detachment is responsible for escorting half of the oil to the wall! If there is an accident, cut it off!"

Undoubtedly, the oil needs to be transported to the wall as soon as possible. The long ladders of those corpses pose a great threat to Qingyan city.

"Yes! Take command!" the leader of the detachment took the order and quickly organized his men to start transporting oil.
