With the lessons learned from the past, the girl will naturally not choose to assassinate directly this time. However, this does not mean that she will give up. Yes, the assassination methods throughout the ages include direct assassination and poisoning!

Just observe carefully, determine Fang Zheng's three meal times, and then look for opportunities to poison him!

Of course, this is not something that can be done in one night. It takes a long time to observe. But fortunately, in the next two days, perhaps in order to find countermeasures, Xiang Yu did not launch another offensive on Hangu Pass.

, which was more convenient for the girl. She observed back and forth several times and found that there seemed to be no difference between Fang Zheng and other soldiers in terms of diet and daily life.

Generally speaking, based on the girl's experience, all these military generals will have someone responsible for their food and daily life. On the one hand, they are generals after all; on the other hand, it is also to prevent being poisoned.

However, Fang Zheng was obviously not so particular. His food was no different from that of other soldiers, except that he would add some more meat and wine and bring it to his room alone.

In this case, the best way is to poison the food on the way to Fangzheng's room. However, although the girl responsible for delivering the food looks weak and about the same age as herself, the girl can feel her.

If your strength is not inferior to your own, rash actions may only frighten the enemy.

However, she can be regarded as a "professional killer", so she naturally knows that opportunities are waiting for her, so the girl will come here every day to stay until night falls and Fang Zheng goes to bed before leaving. In order to find an opportunity to poison him, but now

It seems that this opportunity is really not that easy to find.

During this period of time, Xiang Yu was not idle. He had been thinking about how to crack Fang Zheng's weird weapons. I have to say that he really thought of some methods. After discussing with Fan Zeng, Xiang Yu decided to use the existing catapult.

Moved back again, no longer trying to bombard the city wall, but first used catapults to launch stones and conduct a "bombing" on the ground outside Hangu Pass. According to the results they obtained from studying the fragments, these so-called "ground fires" should

There is some kind of subtle mechanism that will explode as soon as someone steps on it.

If that's the case, wouldn't it be okay if we just detonate it in advance?

In addition, Xiang Yu also found a way to deal with the weird launching devices on the city wall. He ordered people to modify the ram car and added a thick wooden wall of rolled wood in front of the ram car.

It looks like a forklift. Xiang Yu's idea is also very simple and straightforward. The opponent mainly relies on the weird black cylinder and the ground fire, so he only needs to break the ground fire, then watch the explosion and rush to the city as fast as possible.

, as long as you can climb the city wall and get into a melee, those black cylinders will not be able to play a role. At that time, if you press the army, you will definitely win!

After confirming the plan, Xiang Yu did not attack immediately, but ordered his people to rush to make equipment first. After all, he also knew that the army would be strong at one go, then weaken, and then be exhausted. The first time can be said to be the opponent's surprise, and it was not a crime of war. However,

The second time has obviously lowered the morale of the army. If the third time fails, then Xiang Yu feels that there is really no hope.

It took half a month to prepare this time, and then Xiang Yu gathered his army again and launched another offensive towards Hangu Pass.

"Boom! Boom! Boom!!!!"

The flying stones hit the ground, causing explosions one after another. Fang Zheng stood on the city wall and watched this scene, but he was not surprised at all.

"Well, Xiang Yu is indeed Xiang Yu. I knew he was quite capable."

For Fang Zheng, the mine array is actually not difficult to break. After all, the greatest effect of land mines is not to kill but to intimidate. It is precisely because he does not know how much danger is ahead that he will naturally retreat timidly. But now this kind of rough and direct

This method only works now. After all, when land mines were really popular in history, things like catapults had long since withdrawn from the stage of history.

But now... Fang Zheng had to admit that this catapult was really useful as a deminer.

Most of the stones projected by catapults are large in size and can easily trigger the explosion of mines. At the same time, these large stones are thrown forward and can also be used as walls to withstand artillery attacks.

"Kill!!!"

Amidst the sound of artillery fire and mine explosions, the soldiers rushed over with shouts. They leaned down, carried the ladders used to climb the city wall, rushed through the cracked mine array as quickly as possible, and headed straight towards the city wall.

Rushed over.

"Not bad, not bad, really good."

Looking at the soldiers below, Fang Zheng nodded with satisfaction. Sure enough, the creativity of the working people is endless. Frankly speaking, if he really only built mines and artillery, he would probably be in for a tough battle now.

, but fortunately, Fang Zheng was already prepared for this.

"Send the signal."

Thinking of this, Fang Zheng gave an order to the general beside him, and the latter immediately took the order and left. A moment later, he saw a firework suddenly fly into the sky, and then exploded with a "bang".

"what is that?"

Seeing the fireworks flying into the sky, Xiang Yu frowned slightly. Of course he could guess that this was some kind of signal, but... what kind of signal could this be?

Could it be that Mr. Fang will choose to attack? Or is there an ambush? But an ambush? Xiang Yu is also a famous general. If he attacks Hangu Pass, he will definitely send scouts to keep a close eye on the surrounding area. If someone really bypasses him, he will give him a chance.

That's a joke. He can be sure that the spies have reported before that there are no ambushes around!

It can’t possibly come from heaven…………

"boom!!!"

However, this time, Xiang Yu hadn't finished sighing in his heart. Suddenly, there was an explosion, and then he saw his army blossoming and exploding everywhere!

Yes, in the past, it was the troops in the front who were under bombardment, and Xiang Yu could accept it, but now the troops in the rear are also being attacked at the same time, what is the situation? Xiang Yu had done special investigations before and knew the range of those "instruments"

It was very far away, so he deliberately moved the army far away, but how could it still be bombed?

It can’t be from heaven... huh?

Thinking of this, Xiang Yu trembled all over, and then he hurriedly raised his head and looked at the sky. Then, Xiang Yu's eyes widened in surprise.

In the blue sky, Xiang Yu could see a few dark shadows floating around. Due to the bright sunshine, Xiang Yu couldn't see clearly what they were, but he was sure that they were definitely not clouds or birds!

"Then, what is that!?"

This time, not only Xiang Yu, but also other soldiers saw the strange black shadows in the sky and became nervous. However, what made them even more nervous was what came next. They saw small black dots falling from those black shadows. These

The little black dot roared down, hitting the military formation directly, and then...

"boom!!!"

Another wave of explosions was triggered.

"It's an immortal! It's an immortal!"

"This is magic, run away!!"

This time, the soldiers finally could no longer remain calm. People in this era were more superstitious after all. They didn't know what the thing flying in the sky was, but they knew that it was definitely not an ordinary thing!

That’s right, this is Founder’s third hidden ace—hot air balloon!

With the technology of this era, it is of course impossible to create such superb hot air balloons. In fact, it took Founder a long time to complete these hot air balloons. After all, the only hot air balloons of this era can

The material used is animal skin, and it takes a lot of time and effort to sew such a large hot air balloon out of animal skin!

The next step is very simple. There is no anti-aircraft equipment in this era. Founder just sends people to take a hot air balloon to the sky, and then throws down a bunch of land mines. There is no need for any precision... mature gravity.

Will solve the problem on its own.

"Retreat, retreat immediately!!"

At this moment, Xiang Yu finally lost his composure. Although Fang Zheng's hot air balloon actually had certain limitations, it was not so obvious to him at high altitude. Now that he saw the opponent in the sky, he naturally knew that this was Fang Zheng's handiwork.

, in this case, there is definitely no way to continue fighting!

There is no other way but to retreat!

However, what Xiang Yu didn't expect was that the signal given by Fang Zheng this time was not just for the hot air balloon.

The coordinated operation of aerial bombardment and ground armored forces is the last word!

"General!!"

Just when Xiang Yu was trying to withdraw his troops, scouts from behind suddenly brought news.

"We are under attack by enemy forces!"

Is there really an ambush?!

Hearing this, Xiang Yu's face darkened.

"How many people are there on the other side?"

"Here, this little guy doesn't know, but the opponent has thousands of chariots!"

"Chariot?"

Faced with this unexpected answer, Xiang Yu was really stunned. Since King Wuling of Zhao and Hu Fu rode and shot, chariots have begun to slowly withdraw from the stage of history. But now, chariots actually appear again?

But what puzzles Xiang Yu even more is.

"Isn't it possible to destroy a mere thousand chariots?"

That's right, Xiang Yu also brought thousands of chariots and tens of thousands of cavalry when he marched into Hangu Pass this time. Could he still be unable to defeat a mere thousand chariots?

"That chariot is different, my lord!!"

"I'll go see it myself!"

Hearing the opponent's cry-like reply, Xiang Yu also knew that the situation was not good, and hurriedly mounted his horse and whip, advancing towards the rear. After arriving at the battlefield at the rear, Xiang Yu immediately understood why the opponent's mere thousand chariots made his men so nervous.

Already.

In the past, chariots were pulled by four horses in a carriage, with three soldiers standing on top. One of them was responsible for driving the horse, and the other two were armed with swords, spears, bows and arrows to attack. However, these chariots now appearing in front of everyone are

Completely different, they are completely a huge, closed wooden carriage, with eight horses in front divided into two rows to pull the carriage. These chariots have four wheels, are huge, and are equipped with some kind of crossbow.

These crossbows themselves are also abnormal. They can shoot thirty arrows continuously at one time. Such arrows fired together on the battlefield of Qiancheng are almost enough to knock any enemy to the ground. Although Xiang Yu also counterattacked, those arrows

If the arrow hits the vehicle board, there is no way to cause effective damage to the enemies inside.

This was also designed by Fang Zheng. Of course, according to the original idea, it would be best to be able to create a tank. Unfortunately, this is too difficult to achieve. In this era, there are no engines and it depends entirely on horse-drawn horses. Let’s not say whether horses can do it.

When pulling a heavy artillery piece, the sound of the artillery explosion alone was enough to scare the horses and run away. So as the next best thing, Fang Zheng had to design the most famous repeating crossbow in ancient times - it was the same when used as an armored vehicle anyway.
