The question of the three views cannot be persuaded by each other.

Therefore, after each expressed their opinions and opinions, Ye Ning and Lu Yuan did not continue to communicate.

Instead, he set his sights back on the city walls.

It's just that for Ye Ning's evaluation, Lu Yuan already has a new idea in his heart.

These were all things that needed to be reported to the emperor in secret, and although the emperor did not mention this in the order, Lu Yuan knew very well what the emperor needed.

A person who is valued by the emperor must of course have a specific and complete understanding, otherwise, how can the emperor know people well?

Intuitively?

The battle beneath the walls was unusually fierce.

Compared with the fierce confrontation when defending the city before, at this moment, intercepting the beast tide is really a bit of a meat grinder.

Blocking the surging tide of beasts with flesh and blood is a nightmare that is impossible for these vicissitudes of defenders to wake up to.

As the hours passed, the Canglan defenders began to show signs of rout.

A large number of casualties made the Canglan defenders inevitably retreat, and some soldiers were even frightened by the stimulation and had signs of wanting to escape.

Lu Yuan looked at this situation and waved his hand to let the attendants around him join the battle.

It's just that the main task of these squires is not to fight against the beast tide, but to act as a warlord, and to kill those soldiers who want to escape on the spot.

"My lord! We can't continue like this! The soldiers' battle losses have exceeded forty percent! Even if the Overseers are used, it is impossible to continue to force the soldiers to continue fighting! They are people! Not fairies! They will feel tired and hopeless! Now they must be withdrawn to rest, otherwise they may mutinie or break up on the spot!"

The lieutenant colonel officer came to Lu Yuan's side in embarrassment and shouted loudly.

"At least half the time before support arrives, you must persevere. ”

Lu Yuan said coldly.

"My lord! It's not a question of us having to hold on, it's a matter of the soldiers having reached their limit! They have been fighting for more than ten hours in a row! Except for the first time when they were defending the city, they were able to take turns to rest, and they were always fighting for the four hours after leaving the city!"

The lieutenant colonel's eyes were red, and he continued to roar like a madman: "Your Excellency is high above the temple! You may not know the combat ability of ordinary soldiers! Except for the officers, there is no spiritual cultivation among them at all! At present, this is already the limit of what they can do! If the adults do not let them retire to rest, at most a quarter of an hour, the Canglan defenders will be completely annihilated!"

Completely ignoring Lu Yuan's identity, the lieutenant colonel officer roared directly at Lu Yuan, looking really anxious.

Lu Yuan's eyes narrowed slightly, knowing that what the lieutenant colonel officer said was the truth.

But the question is, if you don't have to pile it up with human lives, what else can you do to stop the progress of the beast tide?

If you don't stop the progress of the beast tide, then what's the point of the previous sacrifice?

Lu Yuan's heart hesitated.

Reason told him that the Canglan defenders really couldn't continue to hold on, and the most correct thing to do was to order a retreat now and return to Canglan City to rest, so after a few hours, the Canglan defenders should be able to recover a certain combat strength.

But this voice of reason has never been able to convince Lu Yuan.

"My lord! What are you still hesitating about! I know that you want to limit your losses to just one place in Canglan City! But the problem is that now it's not that we don't want to defend it, but we can't hold it at all! It is pointless to continue to hold on! We can only let the Canglan defenders be wiped out!"

The lieutenant colonel officer continued to growl.

The expression on his face was completely distorted, and he looked extremely hideous.

"Maybe we can do it in a different way...... Let's try to stop the fairy in a short time. ”

Just when Lu Yuan couldn't make up his mind, Ye Ning suddenly spoke.

"You have a way?!"

Lu Yuan turned his head violently to look at Ye Ning.

"I'm not sure, I can only say try. As for whether it will succeed or not, I don't know. But now it is already obvious that the Canglan defenders will not be able to hold out for too long, it has nothing to do with their will, it is the limit of body and spirit, so whether it can be effective or not, they have to try. ”

Ye Ning said in a deep voice.

"What's the general idea? To put it simply, if it's a whim that doesn't have any viability, then there's no need to waste time. ”

Lu Yuan took a deep breath and spoke.

"My idea is to gather all the life-type spirit guides that can ignite fire in Canglan City and list them on both sides of the north and south city walls to form a long wall of fire. This wall of fire doesn't need to be thick or lethal, as long as the fairy spirit sees that it's fire, it's enough. The length is extended as much as possible, and the formation of this beast tide is an accident, and I think the fairies will not be too persistent. ”

Ye Ning said.

"Fire?"

The lieutenant colonel officer looked dazed.

Lu Yuan frowned and said: "Judging from the empire's research on immortals, fire can indeed pose a threat to low-level immortals, but as long as the immortals who have reached the spiritual cultivation level can basically withstand the damage caused by the flames, are you sure that fire can be useful?"

"I'm not sure, but what I'm trying to say is that the wall of fire wasn't created to kill the fairies, it was just to stop the fairies. The fear of fire should come from the nature of the fairies, and it has nothing to do with whether they can withstand the damage of the flames. Because there is also a huge difference between a flame and a flame. ”

Ye Ning said frankly.

Lu Yuan's expression changed for a while, but in just a few seconds, the hesitant look disappeared on his face, and he gritted his teeth and said: "Do what Ye Ning said! Arrange the wall of fire as quickly as possible, and extend it as far as possible! There should be a standing standard fire-breathing spirit guide in the army, right? Take them all out, don't leave any of them!"

"Yes, sir!"

The lieutenant colonel officer didn't care about suspicion at this time, and after receiving Lu Yuan's order, he hurriedly turned around and left.

"If your method is useless, the wall of fire can't stop the beast tide temporarily, you should know how serious the consequences will be. ”

Lu Yuan said in a deep voice.

"Your Excellency, no matter whether the wall of fire can work or not, the consequences have nothing to do with me, I am just an ordinary senior high school student, and the reason why I appeared on the city wall and saw this war up close was completely out of your request, so you shouldn't say these words to me. ”

Ye Ning said with a smile.

Lu Yuan was slightly stunned, then shook his head with a wry smile and said, "You are right, this matter has nothing to do with you, I lost my temper." ”

"It's normal for anyone under such pressure to instinctively look for ways to decompress. ”
