Chapter 61: Traversal(2)

After the crown was put on, he was turned slightly and fixed on his head.
Lin Xun looked at Dong Jun and blinked.
He: "Aren't you king Arthur?"
Dongjun picked up the wand beside the crown: "I think you are more suitable."
Lin Xun smiled: "Okay."
They turned and walked towards the entrance of the church—the sharp gothic corners made the whole church strange and solemn, and the only entrance was extremely dark.
Approaching, Lin Xun saw the situation inside-murals, pillars and stained glass windows, which were very realistic.
However, at the moment he and Dongjun entered the door--
Lights off.
The door behind him slammed shut.
The entire church fell into total darkness, with five fingers out of reach, and no people around.
"Is this true?" Lin Xun whispered, and then asked Dongjun: "Are you by my side?"
"Here." Dong Jun's voice sounded beside him.
Lin Xun thought: "I can't see the road, maybe we have to find the wall first, and then walk along it."
After a brief silence, he heard Dongjun said: "Do you need to hold it?"
"Ah... yes." Lin Xun said.
In such a dark environment, according to normal logic, of course, it is necessary to hold each other so as not to fall apart.
If it is someone else, he has no psychological barriers, and he will even ask for binding.
After the slight rubbing of the cloth, one hand held his wrist.
It was very light, and then it slid down, holding his fingers loosely.
Lin Xun lowered his eyes and his tone remained normal: "Go to the right."
According to the impression when I came in, the opening of the church was closer to the right wall.
Lin Xun is on the right, so he is pulling Dongjun.
The complete darkness will make people feel nothing. After walking a few steps, Lin Xun said: "I feel like we are about to hit the wall."
"Stop." Dong Jun pressed his hand.
Lin Xun: "Huh?"
"There is a button here."
The next second, a dim cold light illuminated the top of the wand, illuminating a small area around it.
Lin Xun smiled: "It really is a magician."
Dongjun: "Come here."
After passing through the colonnade and the hall, two doors appeared at the end of the illuminated area.
This is a castle-shaped labyrinth-that is to say, there will be many intricate corridors, stairs and rooms, and perhaps unexpected things happen. And they have to find a correct way to go out and reach the center of the castle.
Walking through the maze, for Lin Xun, is an algorithm, traversal, or search.
The first step is to choose any path.
Dongjun: "Which one do you choose?"
Lin Xun thought for a while: "Right."
Dongjun: "Then turn right?"
Lin Xun: "Okay."
In the second step, after selecting a direction, every subsequent bifurcation will choose to turn to this side. If it is a dead end, then return to the original road, and then choose another path-then continue to adhere to the original direction, the current fork When they have already walked, retreat to the previous fork and choose again.
In short, as long as you follow this rule, you can walk all the paths in the maze with a very high efficiency, and you can naturally find the target location-much clearer than the headless flies, and the success rate is also very high. It's very simple, but this is the charm of the fixed method-the so-called algorithm, the core is to find a set of fixed methods and processes, so that it can solve many forms of complex problems.
They walked into the bifurcation on the right, and the light illuminated the painting frame on the wall, which was very realistic. There is a hidden door on the wall of this room, leading to a long and narrow staircase, barely able to accommodate two people.
The surrounding atmosphere is very depressing, and with the ubiquitous darkness, it is obviously a maze. It creates a feeling of a haunted house. Maybe this is its charm? Then they can make a gimmick and use it as a way to increase their love.
It is a pity that the two of them are neither couples nor timid.
Lin Xun calmed down the stairs. The wooden stairs creaked and the handrails of the stairs trembled, as if they would break in the next moment.
He felt the rough texture of the wooden handrails, breathing the slightly damp breath of the castle, saying: "It's still very real."
Dongjun: "Virtual reality can't completely replicate the reality."
Lin Xun walked up and said, "That's too much calculation required... But I see a lot of praise for the shell, saying that the holographic experience is very real, how is the Galaxy solved?"
"Montage." Dongjun said: "Just give key information, users will make up psychologically."
Dongjun did not walk side by side with him, but fell a step with him.
Lin Xun: "For example... Only when I am performing complex operations to model in the limited area around me, can the rest be properly blurred?"
Dongjun: "You can say that."
Lin Xun still wanted to say something, but the handrail of the stairs under his hand flicked, and his figure was unstable for a moment.
At the next moment, Dongjun grabbed his arm and pressed against it, Lin Xun stabilized his center of gravity so that he would not fall on his back.
Lin Xun: "...Thank you."
Dongjun didn't speak. Lin Xun recalled the movement just now, and suddenly felt that Dongjun was chosen very delicately. On such a steep staircase, if he has a tendency to fall, Dongjun’s position can be pulled in time whether forward or backward-and if it is walking side by side, or Dongjun walking in front of himself, or There are two steps instead of one step, and there is no way to complete this action.
He thinks Dongjun is very good and very skilled.
Do you often do this kind of thing before?
Lin Xun felt too suspicious.
He forgot this idea and walked the maze seriously-as a game, it was actually very interesting.
After walking up the stairs, the second floor no longer needs wand lighting, and the wall is lit by candlelight. At the same time, there are also knights playing by robots patrolling. They have an aperture of five meters in diameter at their feet, which means the detection range. If they are detected, the player will be caught.
This of course passed well. But it is just to find the pattern of patrol routes, as easy as drinking cold water.
Lin Xun led Dongjun through the patrol knights, and quickly passed through this corridor.
He: "I don't think it will be that simple, but it can be more complicated and add a little more unexpected events -"
As soon as the word "emergency" was spoken, he glimpsed an aperture around the corner and quickly rushed over.
Dongjun seemed to laugh lightly.
The mechanical knight is very fast, and the aperture range is far beyond his companion, almost able to scan the entire corridor.
Lin Xun was suddenly pressed into the corner by Dongjun.
They were very close together, and the breath of eau de toilette was near.
Lin Xun looked up at Dongjun, who was taller than him, and inevitably felt a sense of oppression. Under the dim light, the person's facial features are not clear, but in an instant, he has a dreamlike attraction. Perhaps this is a montage.
He felt something rubbing his heart, and his strength was very light, as light as the fallen leaves on the water, but the ripples spread far away.
The ripples at that moment made him afraid to look at Dongjun's eyes, but instead of looking at the mechanical knight.
The knight's aperture swept through the corridor, but Dongjun's distance was controlled very precisely. At the corner of the corridor-a right angle, it became the dead end of the knight's circular exploration range. He watched the aperture pass by their hiding place, and then turned in the other direction when he was about to touch it.
Watching the knight go away, he relieved a little, and then said to Dongjun: "...well."
Dongjun slowly let him go: "Offended."
"No," Lin Xun chuckled his lips and looked at the other side of the corridor. "There are many corridors on this floor."
With the wall lamp, they no longer have to hold hands, but walk while avoiding the mechanical knight, while chatting indiscriminately-the topic is mainly around a useless but ingenious search algorithm.
At the third floor, things got a little more complicated, traps and institutions appeared, but they were all safe and sound. They walked for a long time according to the rightmost rule-and finally found that they returned to the original starting point of the third floor, which was a closed loop.
According to the principle, this is impossible, the structure here is not complicated, and they have traversed all paths.
He and Dongjun glanced at each other, and then turned to the fork on the right.
After five turns, they pushed an oversized painting of Our Lady. Behind the painting was a dark door. After walking through the passage, a spiral staircase appeared in front of me.
At the end of the spiral staircase, the lights are dazzling.
A sword was inserted in the jade, dark silver, with red stripes, and it was the sword of the red chick.
At the same time, a person wearing a knight's armor slowly turned around, gazing at Lin Xun through the gap of the helmet.
Lin Xun: "..."
Real man Yufeng: "..."
The real sword of the imperial real wind pretending to be a sword knight was pointedly and slowly opened his mouth-Lin Xun had heard it countless times. Feng Zhenren recites the lines.
"Pull out the holy sword and become the king of the holy England empire," the sword knight's voice was old and powerful. "Unless you defeat me, you are not qualified to touch the hilt."
"But I don't have a sword," Lin Xun tried to imply that Yufeng lived to release the water. "Why don't you let me pull the sword first?"
Sword Knight: "I will not believe your deceitful words. I can fight with you with bare hands."
Is it really necessary to fight?
He tried to imply that Yufeng was real.
Real Man Yufeng didn't seem to receive a hint.
Just when Lin Xun was thinking about rhetoric, he heard Dongjun said beside him: "I can fight against you instead of him."
After a moment of silence, the knight said: "A loyal follower is one of the conditions for becoming a monarch, and I will allow you to touch the holy sword."
Lin Xun felt that the real person of Yufeng still got a hint, and he responded in a random manner to make the water discharge natural this time.
But he must not be able to step forward on his own.
He began to perform: "I asked to come forward with my magician."
The swordsman knight cooperates with the performance: "I allow."
Lin Xun pulled Dongjun forward.
At the moment when they walked up to the stone platform, a light hit them, and there was solemn music around them. A short film about the legend of King Arthur was played behind them-this may represent the game clearance, the whole process does not need to touch the sword body,
The sword guard knight took a box and said it was a reward for customs clearance within a specified time.
Lin Xun glanced at him.
The Sword Knight cleared his throat: "If you can really pull out the sword at the amusement park activity this month, you will get a bigger reward package."
Sure enough, how real Yufeng could allow people who come here not to pull their swords.
He looked to Dongjun: "You pull first."
This requirement is extremely normal, and no one can hear the greasiness.
Dongjun seemed to smile, his right hand slowly holding the hilt.
His fingers are slender and beautiful, and his joints are distinct.
Lin Xun looked at it without blinking, and saw Dongjun's fingers clenched tightly, as if pulling his sword with force—but five seconds later, the scene remained unchanged.
Dongjun let go of the hilt: "Can't pull out."
Lin Xun breathed a sigh of relief. His mood was a little complicated for a while, and the future of the realm world was even more dangerous, but Dongjun was indeed not a person in this world.
Just thinking, his eyes on Shang Dongjun.
Dong Jun glanced at him lightly, his eyes seem to be smiling, but this expression made Lin Xun slightly guilty, and always felt that this person had already seen him through.
Only listen to Dongjun Road: "You come."
Lin Xun had no other choice but to hold a sword to perfunctory—as early as Qingcheng Mountain, he had pulled this sword and could not pull it out.
This time it was the same, the sword was still, and it seemed impossible to pull it out of the stone.
But at the next moment, with the concentration of attention, the complex code interface on the Chi Xiaolong bird sword appeared in front of Lin Xun like last time. Antivirus program that exceeds the current level.
Unlike last time, there is now a copy button representing the removal technique.
Lin Xun remembered the sentence on the title page of the cheats.
Removal, used on friendly or non-life.
Non-life.
At this moment, Lin Xun suddenly knew what he should do.
