The demon beast leaped sharply, jumped to the side, and dodged.

Mu Ling said to the soldier next to him, "Go and pour down the black oil!"

A few meters away, there was a large wooden barrel with a barrel of black oil inside. These black oils are extremely flammable and emit billowing smoke.

They are not afraid of fire, but their eyes are sensitive and they are afraid of smoke.

Now the western region has almost reached the point of losing ground, and black oil is the key to their victory.

Several soldiers hurriedly ran towards the black oil, and the demon beast saw the guard's intentions, let out a roar, and rushed towards the soldiers.

The wood spirit stopped in front of it and stabbed at the demon beast with a single shot.

The demon beast waved its claws, trying to resist.

The Wood Spirit spear trembled, changed direction, and stabbed at one of the front legs of the Demon Beast like lightning.

The demon beast stumbled on its feet. The wood spirit swung his spear and stabbed the demon beast in the eye.

The body of the demon beast collapsed with a bang, and the wood spirit withdrew the spear.

The demon beast was panting for breath, not dead for a while.

The wood spirit turned to leave, and at this moment, the demon beast jumped up, swung its claws, and turned to the back of the wood spirit.

Mu Ling heard movement behind him, and hurriedly turned to look, and the spear in his hand blocked him like lightning.

The claws of the demon beast gripped the spear of the wood spirit, and slashed the spear into two pieces. The force caused the wood spirit to stagger backwards, until it reached the vicinity of the pheasant, and then fell off the pheasant.

The demon beast fell to the ground with a bang after the final blow before death, completely dead.

The wood spirit fell from the wall, waving his hands in vain, trying to catch something, but could not catch anything.

Suddenly, a Yuan Force long sword pierced into the city wall from a distance, accurately piercing through the clothes on the back of the wood spirit.

The wood spirit hung on the Yuanli long sword, saving him the fate of falling to the ground.

Mu Ling looked in the direction where the long sword was shooting and saw Wu Song standing there.

Just now, Wu Song saw Mu Ling fall from the city wall, so he made a timely move and saved the other party.

The wood spirit was hung in the middle of the city wall at this time, and there were many demon beasts nearby. Several demon beasts saw the wood spirit and pounced on him.

A few more Yuanli long swords shot at them, accurately hitting the eyes of those stray demon beasts, killing them.

Mu Ling took the opportunity to get down from the Yuanli long sword, stabbed the tip of the spear with his hand to immobilize his body, and then pulled out the dagger at his waist and stabbed it into the city wall higher.

Wu Song continued to shoot Yuanli long swords on the ground, repelling the terrifying demon beasts that attacked the wood spirits.

The wood spirit crawled on the city wall with spears and daggers, and soon climbed to the top of the city wall.

The soldiers had already opened the barrel with the black oil, and next to the barrel there was a ditch on the ground, and the ditch was along the city wall, and every two meters, there would be an opening so that the black oil could flow out of the ditch.

When Mu Ling returned, he ordered the soldiers to dump the black oil.

The soldier overturned the barrel, and a large amount of black oil was poured from the barrel into the trench.

Then, it followed the exit and flowed to the city wall.

In the blink of an eye, the black oil covered half the height of the city wall.

The Wood Spirit took the torch from the wall and threw it down.

The black oil was ignited in an instant, and half of the city wall was ablaze. Billowing smoke came out, and a pungent smell filled the air.

At first, the monsters on the walls were still running in the black oil flames, but after a few moments, they fell from the walls one by one.

Even the demon beasts under the city walls writhed their bodies and howled in pain.

It didn't take long for them to retreat.

The demon beasts in the western region were all repulsed, and the defenders in the other three regions also ignited the black oil, and the demon beasts were also repulsed.

In the blink of an eye, all the demon beasts outside the fortress were gone. The first round of attacks of the demon beast is over.

Wu Song and the Spirit Rhino Demon Beast entered the fortress and joined the others in one place.

According to previous experience, after the first round of attacks, the Demon Beast will repair for one to two days before attacking again.

So, the defenders in the fortress had some respite.

The attack of the demon beast caused heavy losses to the defenders in the western region. Not only did they lose a large number of soldiers, but they also lost a captain.

The fortress must find a way to fill the defensive holes in the western region, otherwise the fortress will be in danger when the next demon beast attacks.

Musa sent the Wood Spirit to the Western Region to serve as the captain there.

However, it is not enough to have a wood spirit, and he needs to send a few capable men to assist him in defending the city.

However, the defenders of the various areas have already been decided. There are no extra manpower to send to the Wood Spirits, but without their right-hand men, the Wood Spirits will not be able to hold the Western Region.

At this time, Mu Ling proposed a solution, that is, let Wu Song and them join the Western Defenders.

Wu Song had saved Mu Ling's life before, showing his strong ability. If Wu Song joins, he will definitely be able to hold the western region.

Originally, Musa was reluctant to let outsiders defend the city, but at this time there was no other choice. In this way, Wu Song incorporated the three of them into the defenders of the western region.

The defenders in the western region are only a problem, and there is a more serious problem, that is, the attack of the demon beasts this time is even more difficult to deal with compared to the previous ones.

The previous attacks of the demon beasts were all attacks by the demon beasts that came to attack the city alone. And this time, the demon beast launched other demon beasts.

In the previous siege, Motomu Beast cooperated with Magma Monster Snake and other demon beasts to complete a pit one meter deep at the bottom of the city wall.

The walls were almost twenty meters thick, and the pit itself could not pose a threat to the fortification of the walls. However, this is a very dangerous sign.

This means that these monsters have learned to cooperate and are gathering all their strength to deal with the Guardians.

Today, they can work together to dig a hole, and who knows what tomorrow they will do.

For example, if the cave in the ground before, if it wasn't discovered because Wu Song was looking for the spirit rhino young beast, then at this moment, the fortress would have fallen.

The defenders in the fortress blocked the cave in advance, which ruined the monster's plan to attack the city with magma.

Caves and pits, these siege methods, which were not available in the previous raids.

In addition to the participation of other demon beasts, there is another point, that is, the number of demon beasts is obviously more than before.

In short, this attack of the Demon Beast was very different. They woke up early and called on the monsters they could control to attack the city.

This kind of signs, it seems that on the surface, the demon beast is in a hurry to break through the fortress, why is this?

No one can answer this question, but a pressing question before the defenders is, how are they going to respond?

The defenders of the western region almost failed to hold the city wall, indicating that it may not be possible to hold the city wall with the current means of defending the city.

This means that they have to change accordingly.

Five hours after the end of the battle, Musa convened a plenary meeting to discuss how to defend the city.

Wu Song, as one of the guards in the western region, was also taken by Mu Ling.

The main issue discussed by everyone was how to change the arrangement of the city defense to deal with more fierce monster attacks.

Others proposed several methods, but after discussion, none of them passed.

Wu Song thought of a way and said, "The only weakness of the demon beast is its eyes. The Black Oil attack shows that their eyes are vulnerable to smoke. ”

Another general said, "The smoke from the burning of black oil can indeed hurt the eyes of the stunner, but that damage will only last for about an hour.

After that, the sorrow will return to normal.

A siege operation will last at least two hours. Therefore, the Black Oil attack can only relieve the pressure on the defenders, but it cannot determine the outcome of the battle. ”

Wu Song said, "Yes, then if we can create a poisonous smoke that will deal a fatal blow to the eyes of the demon beast, then maybe we can grasp the advantage of the battle." ”

Another general said, "However, we only have black oil in our hands, and there is no other poisonous smoke to use." ”

Wu Song said, "So, we need to start preparing a poisonous smoke now." I know a little bit about refining medicine, and I have the confidence to prepare that poisonous smoke.

However, I need a living demon beast to experiment. ”

"But where are we going to find the living demon beasts?" said one of the generals, "and now the demon beasts under the city walls are all dead. ”

Mu Ling said, "We can take the initiative and catch a live one." ”

"Isn't that a death for nothing?" said one of the generals, "the demon beasts all move in groups, even if the defenders of our entire city go out together, once they enter their territory, they will almost certainly not survive." ”

"There are no absolutes," Wu Song said, "Before the Demon Beasts attacked the city, I was outside the city, fighting several Demon Beasts, and successfully killed them.

We don't need your people to help, I'll take the wolf and the bamao, plus my spirit beast, I think that's enough. ”

"I'll go too!" Mu Ling said, "I think Wu Song's plan is feasible, and I want to do my part." I have lived in this place of purgatory for decades, and I am very familiar with the terrain, and I can help you. ”

Wu Song looked at Musa and said, "Patriarch, what do you think?"

Musa pondered for a long time and said, "I agree with your plan.

It is estimated that the demon beasts will attack the city again in five to six hours, and in the meantime, I will open the gates and wait for your return. If you don't come back after the demon beast attacks, then I won't be able to take care of you. ”

Wu Song said, "We must come back before that and prepare the poisonous smoke." ”

Musa said, "Waiting for the good news." ”

There were a total of four people to carry out this plan, Wu Song, Jiang Wolf, Ba Mao, and Mu Ling, as well as the Spirit Rhino Cub.

They left the fortress and headed to the Monster Beast habitat.

The previous defenders had sent people to visit the habitat of the demon beast.

There were three habitats they found in total, and the closest one to the fortress was a valley with lava flowing. Wu Song: They rushed to that valley.
