Tang Xin's habit after encountering difficulties is to open her treasure notebook full of coordinates, NPCs and dialogues, most of the clues in the game are messy and numerous, a plausible sentence, maybe it is the clue to solve the puzzle, Tang Xin's good habit is to record the clues she thinks are important in the notebook.

This method has been tried and tested repeatedly, if it weren't for the fact that she was too popular as a killer of the Tang family, making it seem as if she was synonymous with murderous maniacs in the game, maybe she would be famous for solving advanced quest chains, epic quests, and hidden quests......

Don't mention this, Tang Xin opened the notebook, starting from the part related to the Rainbow Lighthouse and the task, the first thing he saw was the little poem sung among children, and the part that mentioned the Blue Lighthouse was like this.

……

The color of the sea will not be unaware,

But close your eyes and you'll see the treasure

……

Do you have to close your eyes to walk the maze, Tang Xin's first thought was this. She immediately closed her eyes, stretched out her hands, and reached ahead, groping like a blind person...... Touching and touching the touch, something was wrong, Tang Xin opened his eyes, oh, it turned out that Wen Ergongzi, who went to the surrounding area to investigate whether there were any clues, came back, Tang Xin touched and touched Wen Ergongzi's chest.

"Oh, I'm sorry." Tang Xin's face was as usual, he calmly withdrew his hand, and commented in his heart, Well, the chest muscles are good, I didn't expect Wen Er, this guy, looks thin and weak, but his chest is very strong, it feels hot to the touch and feels powerful, not as weak as he looks...... It looks like I'm secretly practicing!

"Heh, I found a cave, it seems a little strange, let's go take a look......" Second Prince Wen squinted slightly lazily, chuckled lightly, and then led Tang Xin to bend over and crawl through several deep pipe-type caves, and came to a somewhat narrow cave.

The cave is only less than three meters high, standing about three or five people is already a little cramped, with Jing Jiu, a strong man with one person on top of three people, Tang Xin even turned around and stretched out his hand to feel that he would hit the uneven cave wall, or Wen Ergongzi in front of her, and the cave was very humid and warm, mixed with the smell of mold, the moisture of ** and the smoke of saltpeter gunpowder in the cave...... It's very uncomfortable.

"What's so special here?" Tang Xin looked at Second Prince Wen suspiciously, except that it was much smaller, more humid, and smellier than the mine they had passed through before...... Tang Xin didn't find anything special.

"Look here," Second Prince Wen moved his body with some difficulty, his back pressed against the cave wall, and the gap in front of him was let out, so that Tang Xin, who was standing behind him, could see the stone wall that he had blocked just now.

"Brother Jiu, it doesn't seem to be suitable for you here!" Tang Xin teased that he was standing there standing on the side with a pestle on the ground, not moving, like Jing Jiu, who couldn't move in the narrow cave, could only slightly hold the shoulder of Wen Ergongzi, and poked his head over on one leg......

I saw that at the position of the cross-section height of a normal person, there were two lines of small characters chiseled on the wall of the cave with tools, and the text was written in the language of the earth elves, and now Tang Xin, Wen Ergongzi and Jing Jiu, who are of human race, cannot be understood, but Tang Xin used to be the third-turn great thief of the night elf clan before, and he is also an engineering master who has advanced to the grandmaster level......

In order to understand engineering drawings, Tang Xin learned dwarven language, goblin language and dwarf language...... So Tang Xin is familiar with these languages. The lingua franca is usually English or Chinese...... That is, in reality, each race has mastered the lingua franca. Depending on the race, there are some special languages, such as Underworld, Dragon, Dwarf, Elf, Giant, Goblin, Primitive, Celestial, and Abyssal languages.

This moderate language has different dialects in different regions, for example, the dwarves living in the Blue Dragon Empire on the eastern continent of Huaxia are speaking dwarven language with the dwarves living in Louisbourg on the western continent. However, there will be differences in individual vocabulary.

Each language has its own script, for example, the underground language is written in the Rylanic script, but the goblin language is written in the same language as the lingua franca, it is also a universal script, so even if Tang Xin and the three of them have not learned the goblin language at present, they can still understand it just by looking at the literal meaning.

It's like Chinese reading Japanese, and although the pronunciation is different, you can't communicate, but because you borrow a lot of Chinese from Japanese in writing, you can still understand the general meaning of a Japanese paragraph with a lot of kanji and few hiragana business cards Chinese.

The meaning of these two sentences is probably like this, time is money, goodbye my friend, night has fallen, good night.

Time is money, it is a phrase that goblins often hang on their lips, and they do implement this sentence with their actions, thinking about how to grab money every minute and every second...... This is probably the most common phrase of all goblins.

Combined with the latter words, taken literally, it seems that night has come, this goblin is ready to sleep, and he is in a hurry to rest, so he says goodbye to people.

But in a cave labyrinth, this abrupt phrase appears, what does it really mean? Could it be that there was once a goblin who was trapped here and wrote this sentence before he died, and then the corpse was decomposing and gone......

No, no, no...... That means that this is a useless sentence, there is no way out here, so the goblin wrote his last words and died, the system can't go to great lengths to do this kind of boring scene in the depths of a labyrinth, there must be some deep meaning, so rule it out.

Or maybe there really is a goblin passing by here, resting here for a night, and at night because he is too bored, he writes something on the cave wall, similar to some people who go to a tourist attraction and write "xxx to visit here".

But it doesn't make sense, if it's really a typical goblin who implements that time is money, and won't waste time on this, they would rather rush forward with their heads bored, or sleep on the spot, and they won't have the spare time to chisel out such small words on the wall with a chisel.

"Time is money, goodbye my friend, night has fallen, good night...... What do you think this means? Tang Xin asked, she touched the stone wall with her bare hands, wanting to see if there were any mechanisms or secret passages around the words, but this narrow cave was so big, Tang Xin basically searched through the carpet, and still found nothing, is there really no mechanism or something?

"Usually relatives and friends will say good night at night, good night also means that I hope others can sleep well in a warm and safe place and have a good dream, night has come, that is, at night, when you rest, then compared to the previous time is money, this may be a description of the goblins' busy money-making life during the day......" Wen Ergongzi reasoned slowly, "Then this sentence is actually a blessing among the goblins, I wish you can seize the time to make more money during the day, and after nightfall, you will have a good rest." ”

"Uh-huh." Tang Xin nodded noncommittally, she could see this, but what did this have to do with solving the problems they were facing now? She had already looked around, and there was no hidden passage or totem carving in the hole......

"Your guess just now is right, there must be a secret passage or secret room here, but we still ignore something important......" Second Prince Wen made a judgment.

"But I really didn't find it......" Tang Xin shook his head depressedly, and suddenly something flashed through his mind, "Wait! I seem to have something in mind......"

But the thought that flashed just now had already disappeared without a trace, Tang Xin shook her head and tried her best to recall, but she couldn't think of anything, so anxious that she stomped her feet.

"Don't worry, let's take our time...... Let's put ourselves in the shoes of a goblin, if a goblin who wants to get through the secret passage of guò walks in, how will he get in? Second Prince Wen stopped Tang Xin from continuing to torture himself, and said from another aspect.

Tang Xin's understanding of the goblin race in the game is still relatively deep, which is all due to the fact that when she was studying engineering, in order to obtain an important drawing and some unique accessories, she was once called by a stingy engineering master goblin NPC for a month of game time, and that experience was really the darkest time of Tang Xin's game career.

"If it was a goblin, then he must have walked into the cave in the shape of a pipe with an upright body, maybe he would have a ** bag behind him, and a flashlight in his hand, and then it would stand in this cave, look around with a flashlight, if there is any unknown danger, and finally follow this sentence at eye level with him." Tang Xin imagined it for a moment and described.

"How tall are goblins? Multiple? Second Prince Wen asked.

"The average ordinary goblin is about 3 feet and weighs about 50 pounds, just like an 8 or 9-year-old child, bear goblins and goblins are not all the way, taller and heavier than humans, it must not be their ......" Tang Xin subconsciously replied, suddenly, the inspiration that had just flashed appeared again, Tang Xin exclaimed, "Ah! I know! That's it, we're going to simulate the weight of a goblin, and then we're going to shine the light on this sentence and just read it out loud. That's what I just thought of. ”

This is still when Tang Xin didn't know where to finish pkking with people, sitting in a small restaurant on the side of the street to eat, and when there were players next to him who bragged about their adventures, I heard from that group of players that they had just heard about it at the time, and it never came in handy, but I didn't expect it to be used after being reborn.

After listening to Tang Xin's words, Jing Jiu's 2-meter-tall giant tower-like body silently burrowed into a passage, filling the entire cave passage to the brim, seeing that Tang Xin and Wen Er Gongzi were really embarrassed and sad...... I don't think I think it usually, but now I suddenly find that I have grown too tall, and sometimes it is a burden.

Immediately after that, Wen Er Gongzi and Tang Xin also climbed out one after another, Tang Xin threw an empty wooden box from his backpack, about the weight of a goblin, and then shone it at the line with the light technique, and said loudly: naluwangisyshi, bancogoonsiarchi, noonkino

It's also difficult for Tang Xin, who now has no system to help learn goblin language, can still remember the pronunciation of some goblin language, and finally said this sentence pieced together, anyway, it shouldn't be too wrong, Tang Xin complained without confidence, really, after all, it was a matter of the previous life, okay?
