"What", Liu Yun finally knew what was wrong, and suddenly exclaimed, looked at Yin Qinlan directly, and said in disbelief, "You have seen a person fly from this side of Heishui Lake to the opposite cliff in the air, how is this possible."

Yuan Qi'er suddenly froze, challenges are really everywhere, I thought that the town in western Sichuan was located on the border, and I was the number one master, but I didn't expect that there would be such masters, just listening to Yin Qinlan's description, I can also infer a little, I'm afraid that compared with myself, it is only strong and not weak.

Liu Yun and Yuan Qi'er glanced at each other and asked in unison, "Sister Qinlan, have you seen clearly what kind of person you are, or what you look like?" ”

Yin Qinlan smiled, looked at the longing eyes of the two, lowered her head, wrapped her hand around the corner of her clothes, and said with some embarrassment, "The morning before yesterday, I went for a walk on the shore of Heishui Lake, and inadvertently, I saw a person, dressed in a white costume, like a fairy in a painting."

"Ancient costume, fairy", Liu Yun was a little surprised, vaguely thought of a person, and felt impossible, so he couldn't help asking, "Is that person's decoration the same as Sister Qi'er's now?"

Yin Qinlan tilted her head and thought for a long time, and finally shook her head, and said with certainty, "Although they are all ancient costumes, they are different, how are they different, and I can't say it."

Liu Yun still didn't give up, so according to the appearance and decoration of the eldest grandson Mingyue, he asked one by one, maybe because of the mountain wind or fog at that time, Yin Qinlan really didn't remember.

Liu Yun couldn't help but think of an incident, when he saw the eldest grandson Mingyue on the bank of Suzhou Creek, he remembered it very clearly at the time, but he didn't remember her appearance afterwards, and he didn't remember what he said, until he awakened his spiritual power, he remembered them one by one.

So in the same way, the person Yin Qinlan saw, Liu Yun was almost certain, even if it was not the eldest grandson Mingyue, it was probably someone related to her, he didn't know why, he suddenly wanted to meet this person, and he had an intuition that if he went late, he would most likely regret it for life.

Liu Yun is not an impulsive person, everything likes to plan and then move, he did not go directly to the Dawa Ancient Temple, but took Ding Erbao and Jia Lian, and went to the settlement site of the transport convoy, fortunately, the population of West Sichuan Town is not much, plus there is a large-scale evil disease, and many people have left here, the house and the site are very empty, and it is very easy to settle more than 300 people.

Everything is easy to do for the transport fleet, but the biggest problem faced by them is the problem of water, they are not locals, they don't even know where to get water, and then after knowing the location, they look at the steep cliffs, hard as iron ice and snow, are dumbfounded.

It turns out that the so-called water extraction is to dig up the ice and snow and come back to melt into water, what is more painful is that often an iron chisel is smashed down, only to see a shallow white mark, it takes half a day to get a bucket of ice slag, and then carefully, hang down from the cliff of several hundred meters, transport a few kilometers later, and arrive at the camp, but after dissolving, most of them are less than half of the barrel.

In addition to more than 300 people, there are hundreds of mules and horses, and the water consumption of these animals is worth seven or eight strong men.

After Liu Yun saw it, he didn't say much, and directly used three ant robots to synthesize a large water purification machine, which can filter the dirty water in the black water lake or ditch, and he also knows that everyone spares their lives, so it is recommended that the livestock drink first, and if it is okay, the people will drink it themselves.

Or the local residents have lived here for a long time, and they have a deep understanding of the water quality, holding the newly baked filtered water, a little smell, they know that this is real pure water, and they don't talk to the people in the team, they go directly to their own houses to pick up, and then everyone knows that something is wrong.

Some bold, I tasted the filtered water, only to find that there is indeed no peculiar smell, on the contrary, the water after the ice and snow melts, there is a faint metallic smell, at this time even the fool knows how to choose, free filtered water, become a landscape in the town of western Sichuan.

After Liu Yun settled down the chores of the convoy one by one, he appointed Jia Lian as the captain of the guard team, and took turns to be on duty in three shifts.

Liu Yun walked around the camp a few times, and felt that everything was fine, so he started his private work, released all the ant robots from the armored transport vehicle, ordered them to start searching for the source of heavy metals on their own, and then took out their secret weapon, that is, the improved mecha.

From Wuhan to Sichuan Town, after more than 20 days, most of them were on ships, although Liu Yun said that he was very concerned about transportation, but in general it was relatively easy, so he also had time to think about the improvement of the mecha, and the defense capability of the mecha was more than enough, and what needed to be improved was its flexibility.

Especially when crossing the Three Gorges of the Yangtze River, the feeling of being close to the women and children in distress, but powerless, had too much impact on Liu Yun, so it was decided to give the ant mecha the flight function, not to mention flying like an iron man, at least gliding in the air for a while.

When he was about to arrive in West Sichuan County, after many simulations and improvements of the brain, Liu Yun finally improved the mecha successfully, composed of twelve ant robots, ten of which constitute the whole body of the battle armor, and the other two constitute the left and right wings, because the overall shape is too small, it is impossible to use propeller propulsion, I want to learn the iron man, and there is no turbojet engine technology, in desperation, I changed to flapping the wings to fly, to be precise, it is modeled on the bat flight, although it can provide lift and thrust at the same time, It is even possible to levitate briefly in the air, but the practicality is too poor, only about 20 meters per second, and the stay time in the air will not exceed 70 minutes.

The improved mecha, named the Bat Mecha, looks like a set of heavy armor when it is not in flight, with a total weight of more than 120 kilograms, and because the ants have their own anti-gravity technology, the actual weight is only more than 30 kilograms, which is heavier for Liu Yun, but fortunately, it can barely be used.

The biggest improvement of the Batmech is the installation of power, with four mini-engines, a smaller version of the new tank engine, with a volume of 120×120×240 mm, each of which can provide 15 horsepower, and a small 8-liter fuel tank, which is 120×200×480 mm, just with four engines, forming a 120×450×480 mm flat backpack, made of softened wings to form a cape, covering them one by one.

Fortunately, it was late, and electric lights were not popularized in this era, and it was basically dark at night, Liu Yun went home wearing a suit of armor, and it did not cause much sensation, occasionally one or two passers-by met, and they were just stunned, and they didn't think too much, this year in the border town of western Sichuan, there are all kinds of people who wear everything, even those who wear Han Dynasty clothes are not a few, and there is no shortage of one or two crazy people wearing armor, after all, the world is not peaceful, and wearing armor can at least block swords and arrows.

When Liu Yun returned to Liu's mansion, Yin Qinlan and Pang Yuyan were shocked, and soon covered their mouths and snickered, Yuan Qi'er seemed to be familiar with the two girls, and she didn't shy away when she floated out.

Liu Yun didn't bother to pay attention to everyone's strange eyes, and just hummed in his heart, as soon as the sky dawned tomorrow, you will know how powerful this armor is, and he didn't come out to sleep at night, but stayed in the bedroom in armor, under the simulation of the brain, learn how to drive this new type of mecha, as the so-called "grinding guns in battle, not fast and light", fortunately, someone's spiritual power has broken through to the late stage of refining, otherwise the next day, it will not be possible to go out normally at all.

As soon as the sky dawned, Liu Yun went out, walked to the west side of Heishui Lake, looked at the bottomless ravine, and felt a little hairy in his heart.

Yuan Qi'er, the master, is not much better, from the side of West Sichuan Town to the opposite cliff, it seems to be very close, about three or four hundred meters, after all, it is different from the lake at the bottom of the Turtle Mountain, there is no possibility of borrowing, so theoretically speaking, it is possible to glide over by the mountain wind.

But the cliffs on both sides are all rocks piercing through the air, hideous and rugged, the biting wind whistling through, sometimes even the boulders on the cliffs will be blown to pieces, rolling into the deep ditch one by one, there is no echo for half a day, if you are not afraid that it is false, Yuan Qier suddenly faintly felt that the place where she was injured in Chongqing, there was some itching and pain, and she suddenly screamed badly.

Liu Yun was about to ask the master what he thought, only then did he find that Yuan Qi'er was already pale, and he didn't seem to be much stronger, so he suddenly retreated, but when he thought of the bedridden old man and the seven or eight hundred dying villagers, he didn't do his best to do his best, and he couldn't say it.

"Yicheng, you don't want to die", Yuan Qi'er saw someone preparing to take off, and couldn't help shouting in a panic, Liu Yun also realized that the big master was not so indifferent, in fact, he still cared about himself very much, and his heart was also warm, and he signaled to the master to rest assured that he was fine.

The mecha on Liu Yun's body began to operate, the visor was automatically covered, and the hands and feet were automatically wrapped in steel, already forming an impermeable steel man, manipulating the mecha to take a few steps back, forming a runway for running, and the cloak behind it automatically opened, forming a batwing hand connected to the hands and feet, and the four engines had been successfully warmed up, flapping their wings, and gradually began to slide.

Before the strength of the runway, the pale white mecha has begun to rise in the air, following the strong wind, like a bat, flying freely in the air, under the guidance of the brain, Liu Yun quickly became familiar with flying, of course, he didn't dare to play any acrobatics, as for going straight up and down, or moving forward and backward, etc., there was still no big problem, and suddenly thought that a certain master was still by the black water lake.

Liu Yun hurriedly flew the mecha back, slowly suspended by Yuan Qi'er's side, automatically opened the visor, showed a smiling face, whistled, and asked a little proudly, "Big master, do you want to fly with me, Dawa Ancient Temple is on the other side."

Yuan Qi'er's eyes were a little hazy, and she already wanted to cry, Liu Yun is really a bad person, he can fly without saying a word, when he jumped in the air just now, he thought that this fight was dead, and he was suddenly shocked again, could it be that he liked this guy, it was impossible.

Liu Yun saw that Yuan Qi'er didn't react for a long time, and he didn't know what was going on, and he didn't dare to stay too long, staying in the air for 70 minutes, saying that it was not long, and when the thing was done, he had to fly back again, in case it took too long, and the energy was not enough to come back, but it would be a big trouble.
