Linghu Xiaoshan and several deputy generals had already studied this thing.

They believe that this is a weapon of great destructive power that definitely has the ability to turn the tide.

In the past few days, she was training the troops every day, and she was sure that Liu Feng would help her. She was even prepared to agree to any conditions of Liu Feng.

She is even willing to have sex before getting married.

She never considered the possibility that Liu Feng did not have such a weapon.

Liu Feng continued to shake his head.

Linghu Xiaoshan's beautiful eyes twitched, and she suddenly went limp, her eyes full of helplessness.

According to the informant, there are at least 30,000 Northern Barbarian troops outside the city, and there are 20,000 reinforcements not far away.

Fifty thousand people, the daily food and horse feed is an astronomical figure. If the emperor issues an order to strictly investigate the officials in the court, the food and grass of the northern barbarian army will be cut off.

Fifty thousand men counterattacked, fighting to the death, with unimaginable consequences.

She was too anxious and left no room for maneuver.

This completely pushed Tianyong City and Youzhou into a dead end.

"Even if there is, this thing cannot be given to you, and it is not suitable for you to use."

The grenade made by Liu Feng is a jar, a ceramic jar that is easy to break. If you are not careful during the march, it will fall apart if it is bumped into.

There is a high possibility of accidentally hurting one's own people at that time.

He made it just to meet a temporary need and use it as a transitional weapon.

His goal was simple: if he was poor in the future, he would have to have muskets firing in rows; if he was rich, he would have to have thousands of cannons.

Who would use something as unstable and incomplete as a grenade?

After a moment of daze, a ray of light flashed in Linghu Xiaoshan's eyes.

"So, you have a more powerful weapon that's more suitable for our army?"

Liu Feng nodded.

"Then what are you waiting for? Give it to me now."

Linghu Xiaoshan's face was full of joy.

She suddenly stood up and stared at Liu Feng, but when she saw Liu Feng's serious expression, the joy on her face gradually faded.

After hesitating for a moment, he asked.

"Tell me, what conditions do you want before you give it to me?"

Liu Feng stared straight at Linghu Xiaoshan, his eyes filled with incomparable sincerity and love.

He knew very well that in Linghu Xiaoshan's eyes, everything he did with her was a transaction, so Liu Feng was not surprised that Linghu Xiaoshan asked this question.

"I can give you the things, but I have only one condition."

Liu Feng stood up, and his serious expression instantly turned into a deep smile.

"My condition is that you must return safely from this battle."

"Also, from now on we are husband and wife, there is no transaction between us."

"I love you."

"So, don't let your husband worry, do you understand?"

Linghu Xiaoshan's heart suddenly trembled. That warm smile and those words of advice actually made him a little dazed.

This guy?

How did he change?

Is he really that good?

Is he really willing to help me because he cares about me?

Linghu Xiaoshan felt an inexplicable sweetness in her heart, and the questions she had just thought about countless times were no longer important.

Yes, he looks unreliable, but at critical moments, he is more reliable than anyone else.

He did not choose the wrong husband.

"You've been in Tianyong City for so long. Have you ever fought against the Northern Barbarians?"

"Do you know what the northern barbarians are most powerful about?"

Seeing that she was at a loss, Liu Feng changed the subject in time to give her time to adapt.

"Yes, there was indeed a confrontation."

Linghu Xiaoshan put her thoughts aside and answered without hesitation.

"The Northern Barbarians are best at cavalry combat, and they are particularly adept at harassment, and their speed is excellent."

"Furthermore, all the Northern Barbarian soldiers are equipped with bows and long swords, and the vanguard is equipped with spears that are more effective at piercing."

"Their horses aren't as tall as ours, but they are more flexible and have better endurance than ours. A head-on confrontation would be very disadvantageous to us."

"Although our horses have strong explosive power, their endurance is no match for the Northern Barbarian warhorses. In a cavalry clash, we can only have an initial advantage. After a prolonged battle, we will soon be left behind. We can't chase them very far, and even if we try to escape, they will easily catch up."

Linghu Xiaoshan felt a headache when talking about this.

There is no way to change the disadvantages of war horses.

"The Northern Barbarians' army now has nearly 20,000 war horses and over 10,000 high-quality cavalry. However, our Fengling Army has less than 2,000 cavalry."

The Northern Barbarians had the advantage in cavalry, so the Fengling Army did not dare to go out of the city to fight easily, and had to be cautious in every step.

"Indeed, the most urgent task is to eliminate the enemy's cavalry. This is related to the victory or failure of the entire battle."

"How about this? I'll design something for you that's specifically designed to counter the enemy's cavalry."

What Liu Feng thought of was of course the caltrops thrown on the ground. In the Water Margin, when Zhujiazhuang was attacked for the third time, the caltrops were very powerful.

"This thing is simple to make and very practical. Just sprinkle a large number of them along the path the Northern Barbarian cavalry must take. Their horses' hooves will be injured. Finally, set up a large number of chevaux de frise, and the threat from the cavalry will be eliminated."

Liu Feng drew his own design and handed it to Linghu Xiaoshan.

It is very easy to make caltrops. If you use the mold casting method, you can make as many as you want.

"Such a lump of iron?"

“There’s nothing special about it.”

Linghu Xiaoshan looked at the drawings and frowned slightly.

"Look carefully, this thing has six spikes on it, distributed in different positions. No matter how you throw it, there will always be spikes on the outside. The horseshoe of a warhorse is thin, and it will pierce it if you step on it. If it doesn't pierce it, it's okay. The horseshoe and the spikes will slip when they come into contact, and the horse's ankle will be injured, and it will lose its fighting ability."

"Besides, as far as I know, the Northern Barbarians' war horses are not just war horses, but also helpers in daily life. Most of them don't have horseshoes, so this thing is their nemesis."

"If time permits, after making the caltrops, place them in sewage or a manure pit. When you need them, take them out. They will be more lethal."

"The dirt will cause the wound to become infected. Whether it's a man or a horse, it will die within three to five days after returning to camp."

"There's no way to treat them. The best way is to prevent them from counterattacking with their living forces."

The more Linghu Xiaoshan listened, the more confused she became. She hurriedly took note of what Liu Feng said.

"Is this really possible?"

"Soaked in dirt? Does that make caltrops poisonous?"

"This isn't caused by poison, but by bacteria, something more terrifying than poison. If it's a large-scale bacteria outbreak, it will cause a plague."

"Do you understand now?"

"Plague? Bacteria?"

Linghu Xiaoshan looked at Liu Feng, he didn't even know what bacteria were.

"Let me put it this way. Bacteria are tiny bugs that are invisible to the naked eye. There may be tens of thousands of them at a single point."

"Don't underestimate them because they are small. If they gather together, the injured part will bleed and fester."

Just like the human body, it looks clean, but it still has a lot of bacteria.

This Liu Feng is not popular.

If she continued talking like that, Linghu Xiaoshan would probably scrape her skin off while taking a bath tonight.

"So scary?"

Linghu Xiaoshan was extremely surprised.
