The territory of Bashu is surrounded by high mountains, surrounding a piece of Sichuan Basin into the country of abundance.

Daba Mountain in the north, Wushan Mountain in the east, Daliang Mountain in the south, and Snow Mountain Plateau in the west, enclose this basin tightly.

The land route is rugged and difficult, and the waterway is full of dangerous shoals, which has been extremely inconvenient for external transportation since ancient times.

Yang Xi knew that at this time, the Yangtze River could be said to be a slightly convenient passage out of the Sichuan Basin, and there was no highway or tunnel at this time.

Even if it is more than a thousand years later, if you want to enter Shu without taking the highway, the car has to wind on the cliff, which is the most primitive winding mountain road.

The Yangtze River flows through the eastern part of Sichuan to form a series of canyons, the hard rock at the bottom of the river is cross-stemmed, the water flow is turbulent and unfavorable for navigation, the danger of the Three Gorges in the upper reaches, the precipice is thousands of feet, the river trough is deep, the dangerous shoals are intricate, the reefs are numerous, the water flow is undulating and turning, the channel is bent and narrow, it is also a lot of obstacles, and it is extremely risky.

In the south, there is the Wujiang River in the south, and the mountains on both sides of the river are steep, the water is turbulent, and there are many dangerous shoals, which is regarded as a daunting road for water traffic.

In the northern part of the basin, there is only a boardwalk paved on the cliffs, called boardwalks. People walk on it, and dangers arise. Cao Cao walked through it once, and he never wanted to go a second time.

The high mountains and deep valleys in the southwest are connected by ropes, and there are many plateaus and snow-capped mountains in the northwest, which is even more dazed. Therefore, Li Bai's famous poem "Shu Road is difficult, it is difficult to go to the blue sky" left by Li Bai has become a true portrayal of history.

Although Yang Xi said that he had entered Shu, he took the high-speed train at that time, and he arrived in an uproar.

At this time, he personally led the fleet through the Yangtze River into Shu, and it was also a blind man to explore the way, more than 100 Chenhe boats, passing through the winding cliffs.

Don't even think about a big ship like the Yangtze River.

After walking for more than a few miles, suddenly there was a muffled "bang" in front, and the lead boat did a half-spin before stopping.

When I looked closely, I saw that the draft of the boat had become deeper.

Yang Xi hurriedly ordered: "Abandon the ship quickly and release the lifeboat!" ”

It turned out that another ship had touched the bottom reef.

It's okay to touch the shallows, pull it out and move forward, the most troublesome is this kind of reef.

This is already the sixth ship to be directly crushed.

After saving the people on board, Yang Xi ordered again, made a mark, and put an iron stake on the reef, and poured an iron plate on the iron stake, which is the mark, and next time, he will not make the same mistake.

In the long run, this must be the case, and it can provide many conveniences to merchant ships and reduce commercial costs and risks.

If you want to really enter Shu from Zigui, it is even more difficult, Yang Xi decided to take his time.

He wants to mark all the reefs and dangerous places in this waterway, and do something that will benefit future generations.

Although we do not have the strength to build a project like the Three Gorges at present, we are able to do this kind of thing.

Along the way, from Yiling to Zigui, only about 40 kilometers away, Yang Xi marked twenty or thirty dangerous places, these places are either turbulent water, or there are reefs.

When he arrived in Zigui County, the trip came to an end, and Yang Xi ordered the fleet to dock and camp at a suitable place by the water.

There was already a detailed report in Zigui City, and Guan Yu was quite surprised to learn that Yang Xi was there in person.

"I don't want Yang Xi to value this place so much, so he actually came here in person. Today's eldest brother asked Wei Yan to guard Hanzhong, Wei Yan won more with less, and retreated to Cao Cao at Yangping Pass, but I couldn't lose to him Wei Yan. Guan Ping! ”

"The last general!"

"You lead the Flying Song first, set up a hundred flying heavenly spheres, bring enough bombs to the sky, and blow up the grain and grass of Yang Xi's boat. Remember, bring more strong crossbows, Yang Xi, but there are also flying balls! ”

"The last general commands!"

"Guan Xing! You lead the army out of the county with me, and when the fire in the rear of the other party starts, you will lead the army to take advantage of the chaos to cover up and kill, and success or failure will be in this move! ”

"Yes!"

Guan Yu brought two sons to guard Zigui, these two sons are not simple, they are both young and brave.

Guan Yu is full of confidence, thinking that his equipment is now not inferior to Yang Xi, and he has a geographical advantage.

But Yang Xi is no one, since he is here, how can he make low-level mistakes.

When Yang Xi got off the ship, he ordered the flying ball to fly out to detect, and he knew that Zhuge Liang had designed a strong crossbow, so he had already targeted.

Yang Xi personally designed a bazooka, which was the prototype of the bazooka of later generations, made of pure steel, and the warhead was also made of steel, and the gunpowder was filled as the thrust.

To put it bluntly, it is a steel barrel firework, with an extremely long range, but the accuracy is slightly worse.

And there are also leads, which require manual ignition, and the recoil is extremely strong, and it takes two people to cooperate to stabilize and counteract the recoil.

But this bazooka has a range of one kilometer and is very powerful.

As for the accuracy problem, the flying ball is so big, this problem can basically be ignored.

Guan Ping was excited.

I can't suppress my excitement, who is the other party? That's the mighty Yang Xi.

In the twenty years before the Han Dynasty, no one could match the limelight.

What Yuan Shu of the fourth world and the third prince of the world, and Lu Bu, the number one in the world, are still guests at his house.

"It's best for me to blow Yang Xi to death directly with a bomb, so that I will become famous all over the world and make immortal achievements!" Guan Ping thought beautifully while flying.

A hundred flying celestial spheres traveled in a group, although the speed was slow, but after all, they were in the sky, and soon went down the river, and saw the scenery of the river fleet from a distance.

But in the distant sky, there were also hundreds of flying orbs in Guan Ping's line of sight.

Guan Ping had long known that Yang Xi had a flying ball, but he was confident, this strong crossbow was the nemesis of the flying ball.

"Herald! Crossbow aim! Shoot down the opponent's Flying Orb! ”

This was the first major air battle in history.

But before Guan Ping could be happy, suddenly a whistling sound sounded in his ears.

The crossbow was shot out, but inexplicably, several flying balls began to dry up.

Guan Ping took a closer look and was immediately taken aback, only to see that on the flying balls, there were big holes broken out one after another, and the size of the holes was the size of a bowl.

There were two flying balls, and I don't know if it was bad luck or what, the hole the size of the bowl was pulled out of a long hole, and the flying ball fell down quickly.

On the falling flying ball, there was a terrified roar, which really made the heavens and the earth not work.

Hundreds of meters in the air, who can save people.

Guan Ping's panic was not over, and the next moment, several more flying orbs began to fall slowly. This time he saw clearly, it was a pointed thing, flying from the opponent's flying orb.

Guan Ping fought hard and ordered the crossbow to be fully opened, and the two sides came and went, each with its own victory or defeat.

In the end, Guan Ping's strong crossbow was slightly inferior, and when the other party still had more than forty flying balls, Guan Ping himself had already begun to fall.

In terms of destructive power, no matter how strong the crossbow is, but after all, for the sake of range, the crossbow arrow needs to be made thinner, and the destructive power is always not as good as that of the bazooka.

Yang Xi's flying ball that fell quickly repaired it and then went up, but Guan Ping couldn't consume it in the end.

Yang Xi ordered Kou Feng to lead the army to lie down, and when the opponent landed, he surrounded him and captured him alive.

Guan Ping didn't expect that he was captured alive in this way, there was no immortality, but the great shame came.
