It's late autumn, frost and dew are condensed in the morning and evening, and the further south you go, the more humid the air becomes, and the breath is full of cool breath. On the winding mountain road, the sound of hooves is crisp. One hundred and ten healthy horses, guarding a convoy, marched slowly.

The horses were panting, spitting mist, sneezing, and covered with dust, showing that they had traveled a great distance. But it's not because people are sleepy. It's too hard to walk.

It is difficult to go to Shu and it is difficult to go to the sky. Li Mu once took this poem to pretend to be forced, when he said, he didn't feel anything, but now he really has a real feeling, since he entered the river, the road has been circling in the mountains and mountains, even if it is a post road, it is just a few paths dug out of the mountainside, which are extremely narrow, while leaning on the steep cliffs, turning his head, you can see the knife-like rock wall and the surging river under his feet. The vehicle was able to get here, or the result of the Lonely Nine separating the guards from the outpost, encountering a bad road, and temporary repairs.

But since I entered this mountain, I am afraid that it will come to an end. Because there are no roads ahead, only some sheep's intestine paths. Just like Mr. Lu Xun said, there was no road here, but there were many people walking, and the kind of road that stepped out.

The convoy stopped.

Li Mu, who was squinting, shrugged and opened his eyes. Dugu's family came to him with a horse, and said through the curtain: "Big brother, there is no carriage in front of you." ”

Li Mu opened the curtain and looked out, and sure enough, there was no way. He took out the map, compared it, frowned, and said, "Are we lost, is it right to go this way?" ”

"The direction is right." Dugu Jiu replied: "Before entering the mountain, I inquired. The road here is mostly intermittent, maybe it will be good to pass the few miles in front of you, maybe something. ”

"Alas! We still have to build roads! Li Mu put away the map, got out of the car, and said, "The things on the car will be assigned to each horse to carry." The empty car turned around and waited back at the nearest post station. Arrange for a few people to watch, and vacate the horse for the midwife. ”

These midwives had already said before they came. Although it is difficult to trek through mountains and rivers, the price is high after all. During the delivery of the baby, I didn't have to work for half my life, so I didn't complain along the way.

"Report!" The secret guard who was walking in the front suddenly turned around and came back to Li Mu and got off the horse: "Master Hou, I found a boundary monument in front. ”

Li Mu and Dugu Jiu hurriedly stepped forward and opened the wild grass to check. This boundary monument is old, the handwriting is mottled, and it is vaguely recognizable as three words, '〇 state boundary'.

"What state?" There are too many states in Datang, and Li Mu can't carry it. Dugu Jiu had already inquired before and said, "It should be Xuzhou." ”

"Arrived in Xuzhou?" Li Mu was a little surprised, but more of a surprise, when he arrived in Xuzhou, it showed that he was not far from the destination - not far from Fatda.

Yes, Li Mu didn't know where Wang Ou was. The coordinate point of his trip is the road marker stone on Fat Da's body. But he is confident that Fat Da will definitely be with Wang Ou.

Li Mu glanced at the sky, it was almost noon, and the convoy would have to wait for a while to return the same way, so he thought for a while, waved his hand and said, "Rest for a while, eat something." He said to Dugu Jiu again: "Find two people and explore the road ahead." ”

Dugu Jiu nodded, took the water bladder and pastries from the horse, handed them to Li Mu, and arranged for someone to explore the way.

Li Mu put the water bladder under his buttocks, opened the silk cloth wrapped in pastries, and ate it one by one. The rest of the people also eat dry food. The mountains are so humid that I can't find dry firewood, and I want to make a hot meal, which is basically delusional.

Li Mu didn't have the heart to eat, he was almost exhausted.

If you say this, you will inevitably be slandered. Because in the eyes of outsiders, Li Mu was lying in the car all the way, and almost never got out of the car except for eating, drinking, and Lazar. You can get tired from sleeping all day, and there is still this kind of reasoning?

He knows that Li Mu's tiredness is not the tiredness of his body, but the tiredness of his head.

On the second day of departure, Li Mu, who was sleeping, was suddenly forcibly 'pulled' into the consciousness space by the system. He was told that an upgrade was imminent.

Li Mu thought to himself, upgrade and upgrade, what do you want me to do? He wanted to quit and go back to sleep, but something terrible happened, and he couldn't. Then the space of consciousness began to collapse, and all the 'graphical' things became strings. Even Li Mu's body in the consciousness space became a character and integrated into it.

The consciousness space is closed, he can't get out, this can frighten him, he has always advanced and retreated freely before, why did he have convulsions today? I just had a child, don't play with me like this!

Li Mu watched coldly in the chaotic space of consciousness, watching the string change in front of him. I don't know how long it took for him to finally see some clues.

These strings in front of you are so much like the development environment of "The Legend of the Tang Dynasty". So he wondered, since the graphical interface is gone, can he try to save himself, like when the game was developed, to make his own interface.

As soon as the thought moved, the chaotic string in front of him became more familiar.

Li Mu, who had become a mess, couldn't help but want to laugh when he saw this situation.

Can anyone explain which one of the great powers is boring and got me through? It's ridiculous enough to have a system, how come you even have development tools ready for me.

Could it be that this so-called system upgrade is just letting me 'build' my system myself? Like "Minecraft"? 'Editing' a world yourself?

Li Mu felt very ridiculous, but a chaotic consciousness space did not give him a chance to choose. He had to follow the 'system prompts' and try to use the 'telekinesis' to knock on the code.

Not to mention, the mind is faster than the keyboard to type the characters. Almost as soon as the thought moved, a line of code came out. And there will be no character errors, which is not too cool for a programmer.

Li Mu had never felt this way, it was like flying. If you have this ability before crossing over, what hacker white customer, what Silicon Valley elite, which is the opponent? It's no problem for a person to fight a company.

Anyway, it didn't take much effort, and Li Mu in the chaotic state didn't feel tired, so he kept 'knocking' and 'knocking', and I don't know how long it took. He finally restored the graphical interface, and almost the moment he recovered, he was 'cleared' out by the system. The feeling of breathing after a long absence, Li Mu couldn't wait to open his eyes, everything around him was as usual, and less than half an hour had passed.

This made Li Mu a little in a trance, did he have a dream just now.

He checked himself, except for a slight pain in his head, he was very hungry. He had a similar experience when he was practicing internal skills before. At that time, he found that he could use his brain to simulate the CPU, constantly trying the best exercise line, and the sequelae was a headache. Because the operation is too many times, it is like overclocking the CPU, and the brain can't install a heatsink after all, so I have to have a headache.

Could it be that just now, I was really coding in my head?

Li Mu was full of food and drink, and was determined to try again.

Entering the consciousness space, sure enough, the 'programming' ability is still there. The graphical interface is the same as when he left. The so-called upgrade of the system is not visible at all.

Only then did Li Mu understand that the so-called upgrade was to give him the ability to program.

The source data of the system is there, Li Mu tried it, and he didn't have the right to modify it. In other words, if he wants to restore the system, he can only choose to 'install' the data back again, or continue to type in the code.

So what is the use of the so-called upgrade?

Li Mu felt that it was very absurd, it was like assembling a computer. Didn't upgrade the accessories, just changed the chassis. What it was, and what it is now, is of no real use at all. It added a lot of trouble, because if he wanted to use the system now, he had to re-type all the code himself.

The system is the biggest reliance in Datang, and Li Mu can't be lazy if he wants to. Helplessly, he had to hide in the car and type code, so people outside saw that he was sleeping, but in fact he was working overtime. The overtime hours are too long, and the brain is still overheated and has a headache, so I have to 'wake up' to cool down, this kind of sleepless work, Li Mu is really afraid that he will 'crash' one day.

After knocking on the code all the way, Li Mu was already a little numb. When I got off the bus just now, I couldn't tell the difference between the southeast and the northwest.

Li Mu swallowed the last bite of pastry, looked up at the mountains in the distance, and thought to himself, Sister Ou, your husband and I have wasted so much effort to come here, if you don't go back with me, it will really hurt my heart-

While feeling sorry for himself, the pathfinder returned. Dugu Jiu came to Li Mu's side and said, "Big brother, there is no way ahead." ”

"What?" Li Mu looked at Dugu Jiu blankly and said, "What do you mean, what do you mean that there is no way?" ”

"Less than 300 zhang ahead, the cliff has already fallen. We scattered and searched, but we couldn't find a way around it. ”

"How can there be no way?" Li Mu got up from the ground and said, "Take me to see it!" ”

Dugu Jiu had no choice but to take Li Mu over, three hundred zhang, in the blink of an eye. This time, Li Mu saw it with his own eyes, and there was really no way. As far as the eye can see, the three rivers merge, the waves are monstrous, the water splashes hit the cliff wall, fly straight to the waist of the mountain, on the cliff stone wall, there is also a lone tree, the shape is similar to the Huangshan welcome pine, stretch out a 'hand', as if provoking, laughing at Li Mu on the other side of the river can not come.

Li Mu gritted his teeth: "How can there be no way?" Could it be that the people here will never be separated from the world? ”

Dugu Jiu didn't speak, and he came for the first time. Seeing Li Mu standing on the edge of the cliff in a daze, Dugu Jiu stood silently beside him, worried that Li Mu would have an accident in a hurry.

"No, it's impossible to be isolated." Li Mu thought about it for a long time and finally figured it out. It is impossible for any place to be isolated from the world as long as it has a name and a surname. Moreover, Xuzhou, he said that he had heard of it, Xuzhou is infested with mountains and rivers, and Baiyi haunts, so it is impossible to have no access to the outside world.

Li Mu's gaze sank, fell on the turbulent and rushing river, was silent for a while, and said, "Let's cross the river!" ”

Dugu Jiu's lips moved, and he said, "Big brother, I, I'm just watery, in case of us, I'm afraid I won't be able to save you." ”

Li Mu knew Dugu Jiu's temper, and when he said this, he didn't have the confidence to do it. Li Mu looked back at the two secret guards who followed behind him, they were also frowning, obviously not agreeing.

Li Mu laughed at himself, and secretly said that he had taken it for granted. The river is so turbulent, how to sail? Even if they can sail, where does the boat come from, and who dares to ferry?

"There's another way!" Li Mu turned around and said, "Dismantle the carriage, make a hot air balloon, let's fly over!" ”

It works!

Dugu Jiu's eyes lit up, he had seen Li Mu make hot air balloons during the Shangyuan Festival. At that time, the hot air balloon across Chang'an City had already been proven to be feasible. But the hot air balloon is limited after all, Dugu Jiu thought of this problem and said, "Big brother, there are so many of us." ”

"Stupid," Li Mu turned around and walked back, saying, "The road must be impassable, and there must be a place for the ferry." Let's make a hot air balloon first, let's go first, and the others let them find their way, and meet at the agreed place, isn't it? ”

"Then it's better for us to find a way together, so safe."

"No," Li Mu said categorically; "I promised Qiaoqiao that I would have to go back within two months. It's been almost a month, and if I delay it any longer, I won't be able to go back for two months, and she should worry about me. Just do as I say, let's go there first, and the others will find the ferry. ”

Li Mu said this, and Dugu Jiu no longer stopped him. Back to the convoy, Li Mu commanded the dismantling of the car, he took matters into his own hands, using the dismantled wooden square, made a simple frame, and pulled several pieces of silk, and asked the midwives to help make the body of the hot air balloon. The midwives are all women, and the female red will be a little bit, although the stitches are not so neat, but a little more sewing can also reach the fine standard.

Li Mu has observed, the river is only thirty or fifty meters wide, as long as the hot air balloon can fly, it will float over, no matter how good the quality is. For the sake of safety, he also deliberately made two parachutes, one for him and one for Dugu Jiuyi.

The tools were not so handy, and the efficiency was not fast, and it was barely finished until the evening. In the middle of the night, of course, you can't take off. Li Mu asked people to cut down trees and clean up weeds, clear a place, and find a way to light the branches and stew out some charcoal, which will be used when taking off tomorrow.

The next day, the charcoal was cooked. After Li Mu explained the matter, he and Dugu Jiu brought dry food and some money, two changes of clothes, carried a burden on their backs, and climbed into the hanging basket of the hot air balloon. Ignited, the hot air balloon lifted smoothly into the air. Under the surprised gaze of everyone, he slowly floated towards the opposite shore.

It is also a beautiful day, and the wind is blowing to the opposite shore today. The hot air balloon floated smoothly and soon flew half the distance.

Just as Li Mu was about to land, suddenly, an arrow flew from the cliff on the opposite bank, hitting the rope of the hanging basket.

The hot air balloon instantly skewed and fell straight down!
