War is not a dinner party, and crossing is not risk-free.

Liu Jian thoroughly understood this with other people's blood and wails.

The reason why he sat in the city to watch this epic play performed by nearly a million extras was because of the uncomfortable invitation. For otaku living in peacetime, the collision between steel and ** in the era of cold weapons is really too intense. This kind of excitement is definitely not something that can be experienced by sitting in front of the TV and watching a horror movie.

Stamped, a general strode in.

Liu Jian smiled when he saw the person coming: "General Zhang, I haven't seen you for a long time." ”

"Hmm." Zhang Yu nodded slightly: "What's the situation here?" ”

Unlike King Liang, Zhang Yu's attitude towards Liu Jian is not bad.

On the one hand, it is because Liu Jian's performance after that is not bad, but the more important reason is because Liu Jian is a subordinate of the prince.

Everyone knows that there are four people who cannot be offended the most in the Han world, the Son of Heaven, the Queen Mother, the Princess of Pavilion Tao and the Prince.

"But soldiers are indeed good soldiers!"

Although he was a little contemptuous of Liu Jian, Zhang Yu had to admit that the soldiers he commanded were very powerful, not only fighting bravely and not fearing death, but most importantly, ordering and prohibiting. In the Liang Kingdom, only the Liang Wang Guards have such excellent quality.

"Today, Wu Yi has not yet attacked the city." Liu Jian smiled: "Maybe it's because I'm tired from attacking the city for days, so I want to take a break and then strengthen the offensive." ”

"Hmm." Holding the city wall with one hand, Zhang Yu looked at Wu Chu's continuous camp in the distance and sighed: "I'm afraid it will be difficult next." Well? "What's wrong?" Liu Jian took a few steps forward and walked to Zhang Yu's side and looked out, only to see a team of cavalry appearing outside the moat, circling around, as if observing the city defense of Suiyang.

"It's Wu Rebellious!" Zhang Yu's face was a little ugly.

"Wu Wei, Liu Wei?" Liu Jian looked out.

I saw that the group of cavalry was obviously surrounded by an old man with gray hair, who was tall and strong, and looked very strong.

This is Liu Bi?

Although Liu Jian was already calloused by Liu Jian when he heard the name, this was the first time he had seen Liu Bi. From this point of view, the evaluation of Liu Bi's fierce and powerful in the history books is not fake, this old man looks like the kind of fierce general who can fight habitually, although he is old, but he is full of energy.

And Liu Bi, as the commander of the First Army, actually ran to this position, completely looking like he didn't take the defenders of Suiyang City in his eyes, no wonder Zhang Yu's face was not good-looking.

This is not just a provocation, it is simply a provocation.

However, Zhang Yu obviously knew that Liu Fei's purpose was to provoke.

Zhang Yu's brain is not stupid, he knows what Liu Bi is doing when he runs to such a position.

wanted to lure the defenders of the Liang State out of the city to fight.

The strength of the Liang State has been funded and expanded by Emperor Wen and the present two generations, and there are 30,000 elite soldiers who can fight, and there are sufficient food, grass and equipment.

But compared to the Wu-Chu coalition army, it is still a small thing.

Relying on the defense of Suiyang Jiancheng, Liang Guo could also resist Wu Chu. If you go out of the city to fight, you will only fall into Wu Chu's arms.

But......

"It's about three hundred paces!" Liu Jian visually measured the distance.

"It's itchy hands, you have to get it." Liu Jian stretched out his hand and moved: "Take the rhubarb crossbow." ”

The rhubarb crossbow is definitely the benchmark of weapons in the Han Dynasty. The big yellow crossbow developed on the basis of the Qin crossbow has terrifying power, and it can be shot through even the armor of a person within a hundred steps, which is completely capable of the big yellow crossbow.

The most powerful rhubarb crossbow has a power of ten stones and a range of more than five hundred steps. In ancient times, the step refers to taking a step with both the left foot and the right foot, with 60 centimeters as the standard of a step, that is to say, the actual distance of a step is one meter two. Five hundred steps is six hundred meters.

He didn't pull out the power of the ten-stone crossbow, so this crossbow was handed over by someone else.

Liu Jian can use the rhubarb crossbow, after all, he is a man, and when he sees such a representative and legendary weapon, he can't help himself if he doesn't play with it.

Moreover, his archery is very accurate.

The five hundred steps of the big yellow crossbow speak of the maximum range rather than the effective range.

Liu Bi was about 300 steps away from the city wall, which was a safe distance for normal conditions. With the technological and tactical level of the Western Han Dynasty, even if the big yellow crossbow could shoot 500 steps away, its real killing range was still within 50 to 100 steps.

A hundred steps away, a person's face is like a bean, and three hundred steps away is as thin as a hair.

How can it be accurate in this case, it is useless to raise Yuki to resurrect!

Liu Bi stopped at such a distance, and what he was afraid of was not a big yellow crossbow, but a salvo of ballista carts on the city wall of Suiyang.

However, Liu Jian felt that he could give it a try.

"Wu Shun once fought with Emperor Gao, and he was old in the battlefield, and there are three hundred steps away from Wu Shun here." Zhang Yu glanced at Liu Jian: "Mr. Liu, don't do anything meaningless." ”

Three hundred steps is the strongest penetrating distance of the big yellow crossbow, and if someone is shot by the big yellow crossbow at this distance, it is definitely the result of penetrating the person with armor. But that's just theoretical, because the rhubarb crossbow has no head at all at a distance of three hundred paces. Generally, the method of casual mending is called covering shooting, and only God knows whether it can be hit or not.

Even in the ** era, the real effective and accurate range of the rifle is within 50 meters, unless it is a sniper rifle equipped with a scope, more than 300 meters to hit, either a stray bullet, or a east wind.

In Zhang Yu's view, Liu Jian did this completely to bring humiliation on himself.

"How do you know if you don't try?" Liu Jian smiled at Zhang Yu and continued to fiddle with the rhubarb crossbow in his hand.

After a few attempts, he became proficient in the rhubarb crossbow.

It is not impossible to shoot a target three hundred paces away with a rhubarb crossbow.

As long as you can calculate the wind direction, wind speed, and the effect of the parabola on the arrow, and have a pair of eyes as sharp as an eagle, you can completely control the landing point within a radius of 50 centimeters of the target.

Of course, this would be almost impossible without a gold finger.

Liu Jian's intelligence was increased to a full value of twenty points by him.

After adding twenty points of intelligence to himself, Liu Jian did not find that he suddenly became smarter, or had excellent comprehension, and no matter what he learned, he was very fast. My memory has improved a little, but it's not exaggerated enough to remember when I was a kid when I didn't pee my pants.

The growth of his intellectual attributes seems to have increased entirely in one aspect of ability.

What is the result of one thousand one hundred and fifty two thousand five hundred and sixty-four multiplied by eighty sixty-one thousand and twenty-three?

In the past, this problem could only be understood unless Liu Jian brought a mobile phone and took out a mobile phone calculator...... He may not be able to remember the huge number all at once.

But now, after just thinking about it slightly, Liu Jian got the answer.

Nine thousand nine thousand seven thousand two hundred seventy five thousand two hundred seventy two.

His intellectual growth was all reflected in his ability to calculate.

Therefore, the current Liu Jian is a humanoid calculator. For ordinary people, the data that cannot be calculated with the human brain is like instinct for Liu Jian.

Before coming to Suiyang City, he had shot down the flying eagles in the sky with a big yellow crossbow, and it was an arrow into the eye.

At that time, the height of the flying eagle was at least 200 meters.

Now, Liu Bi's distance is only half that of the flying eagle, and the speed of movement is even more like that of the flying eagle.

Of course, even if that's the case, it still takes luck to get the shot.

There are too many variables that can change the final landing point of an arrow in flight in an instant.

For example, a sudden and disturbed air flow.

Breathe deeply......

The arm carrying the rhubarb crossbow is as steady as iron.

Aim for the target......

Wind velocity......

Height......

Gravitational acceleration ......

Parabolic determination......

Final Correction ...... Deflect 3 cm to the left and 2 cm upwards towards the target.

The sound of the crossbow is like a crack!

In an instant, one shot into the soul!

The big yellow crossbow arrow that was like a shadow instantly crossed the distance of three hundred meters, Liu Bi only felt a pain in his cheek, and a huge force drove his body, and he fell directly from the horse.

Zhang Yu was instantly dumbfounded, looking at Liu Jian's eyes as if he was looking at a ghost!
