Of course, Ji Xiang could see that this hand armor was not a toy at all, and the straight knife must have been captured. She glanced at Lu Zheng with concern, and when she saw that he was not injured, she breathed a sigh of relief and wondered, "Brother Zheng, what happened?"

Lu Zheng waved his hand at her, signaling that he would talk about it later, and his eyes kept wandering on Bluefin Miaoyue's body. From the mouth of this little girl, I learned that there had been a rebellion in the merman tribe, and the merman princess personally led the army to quell the rebellion.

This armor and straight knife are obviously from modern times, if they are really from the hands of merman craftsmen, which means that there are other mermen who have survived in the world and have come into contact with modern science in addition to the bluefin Myotsuki.

"Miaoyue?"

"Huh?" Bluefin Miaoyue was still studying the straight knife, and without waiting for Lu Zheng to ask, she touched the back of the knife by herself, shook her head and said, "This skill is not good, it is flawed." See, the thickness of the back of this knife is inconsistent. And the sand in it, which is diluted and poured into the blood tank, what is the effect? How strange...... There is also this knife handle, and there are two small screws that Sister Jixiang said here. Who did this, I didn't even dare to leave a sword inscription, I was really blind for half a dozen steels. If it were for us, this kind of craftsman would at least have to punish him to go to the Turbulent Valley to think about it......"

The little girl talked endlessly, as if she was completely immersed in the world of skills, and her words were tinged with a touch of disdain. To sum it up, the quality of this knife is worrying, and it is a terrible thing.

Lu Zheng: "......"

After talking for a long time, she found that no one responded, so the little girl reacted, blinked her watery eyes, looked up at Lu Zheng at a forty-five degree angle, and said strangely: "What's wrong? ”

"Ahh ”

Before Lu Zheng could speak, she just sighed, remembering that this was a gift from Lu Zheng, and it was obviously very impolite for her to talk about her shortcomings like this. As the successor of the leader of the merman who has been educated in court etiquette, it is simply unseemly to despise the gift of the dragon king.

"Oh......" The little girl stuck out her tongue and said, "Actually, it's not that bad, at least the whole of this knife has some charm of cutting off waves." Well, it's not bad, I kind of like ......."

Well, Lu Zheng was a little speechless, and said with a wry smile: "This is actually the trophy I captured last night, well, this hand armor is only a part, and he is wearing such armor all over his body." ”

"Whole body armor?" the little girl thought for a moment, "It's not difficult to forge." You can first make a page with Kun steel, and then glue it with Xia mulberry glue......"

It was another on-site teaching of blacksmithing, and Lu Zheng's eyes widened, just like a child who had just entered kindergarten and was exposed to the calculus of all evils.

Ji Xiang smiled, and the flowers trembled.

After finally listening to her, Lu Zheng was afraid that she would think of something again, so he hurriedly said: "Yue'er, after the princess of the merman blocked the abyss, are there any other mermen left in the world?"

"Huh?" Bluefin Miaoyue was stunned, lowered her head in frustration and said, "Our Bluefin clan, I escaped, and it became like this." As for the other mermen, if they live, unless they ......"

"Unless what?"

The little girl glanced at Lu Zheng and said, "Unless you are nourished by the true liquid of Tianshui, there is no way to survive." ”

"Tianshui real liquid?"

"Hmm. The little girl nodded and said: "Our merman is transformed by the scale debris in the Tianshui True Liquid that Yang Long leaked when he infiltrated the earth's core, and every thread year, we need to soak in the Tianshui True Liquid in order to continue to survive." Moreover, the forging techniques that we shark people are proud of include water forging and fire forging, of which the water used in the water forging method is the true liquid of Tianshui, and the fire forging method uses dragon fire. It can be said that we sharks only have the meaning of survival if they are attached to the dragon god. ”

Her meaning is obvious, the merman must rely on the dragon king, otherwise it will be difficult to survive. Sharks can't do without dragons, just like fish can't do without water.

Thinking of this, Lu Zheng's expression changed, and his heart sank. According to this reasoning, the mermen who forged this armor can survive, there must be a dragon behind them to protect them, and this dragon, like Lu Zheng, holds the true liquid of Tianshui.

A name flashed through my mind like lightning - Aoqing, the evil dragon.

Ao Qing is not a pure-blooded true dragon, but he used poison to kill the son of the second prince of the South China Sea, seized its dragon ball, and maybe mastered the ability to refine the true liquid of Tianshui.

To date, Ao Qing is the only dragon race he currently knows.

So that's the most logical answer.

In the battle of Chang'an City, Ao Qing appeared briefly and must have noticed the rising Lu Zheng. With his self-respecting ambition and ruthlessness towards his relatives, he will never coexist peacefully with Lu Zheng.

If he learned that Lu Zheng had also inherited his father's Dragon Palace and was the Dragon Monarch of the South China Sea, he would inevitably be furious and unscrupulous to get rid of Lu Zheng and seize the Dragon Palace. Because he is the rightful successor.

"Brother Zheng, what's wrong?" Jixiang noticed that something was wrong with Lu Zheng's expression, and he looked worried.

Lu Zheng really couldn't be calm, Ao Qing's threat to him was too great, even bigger than the Golden-winged Dapeng and Pipa Yama.

There are no two dragons in one water, good and evil are not separated, and only one of the two of them is destined to survive to the end.

Lu Zheng took a long breath, glanced at Jixiang, and said with a smile: "It's okay." Then he picked up the horizontal knife with great interest, smiled at the bluefin Miaoyue and said, "Yue'er, if you are given enough materials, can you make such a knife?"

I thought that Bluefin Miaoyue would nod confidently, but unexpectedly, she actually shook her head, pursed her lips and said, "It's okay to create an appearance, but I think there are other things in this screwdriver handle." As she spoke, she picked up the small taper and removed the screws, revealing an alloy keel on which the black PCB board was secured.

"What is this? I don't see it. ”

"This is the circuit board. ”

"What are circuit boards for?"

"Well, the circuit board is ......" Lu Zheng wanted to explain, but found that he didn't know how to explain, after all, this thing was also a black sight for him.

After hundreds of years of change and development, modern science has become very mature and is the crystallization of the wisdom of countless geniuses. Often a seemingly inconspicuous thing involves advanced knowledge such as mathematics, physics, chemistry, electromagnetism, and quantum science, and every discipline is an unimaginably large chain of knowledge.

In this case, it's like Bluefin Miaoyue can skillfully disassemble and assemble a mobile phone, but she can't comprehend the infinite knowledge hidden in it.

"Circuit boards, we have to start with electricity......

"Isn't electricity lightning? Isn't lightning your magic trick? Eh, you invented the circuit board?"

“……”

"It's not lightning in the sky, it's called a battery, and there's electricity in it. ”

"Is the battery?Is the battery a pool for electricity?Is the battery also a magic device that you invented?......?"

“……”

It seems that if you want this little girl to change from a traditional craftsman to a modern craftsman who has mastered the core technology, she must start from the most basic knowledge. Lu Zheng can conclude that if she goes to school, she will definitely surpass the existence of the scholar - the real god of learning.

It seems that the plan for the cultivation of great scientists is going to be put on the agenda.

"Yue'er, the technology of mortals now, to some extent, is not inferior to that of mermaids. It's not because you're stupid, it's a limitation of the times. So, we should start with basic mathematics, physics, etc. ”

Faced with this little girl who was thirsty for knowledge, Lu Zheng patiently explained the current scientific scope.

The little girl nodded confidently and said, "Is math arithmetic?" ”

"Really?"

Lu Zheng smiled and groaned, the terrible subject of mathematics had been his nightmare for many years, and he was trying to show off his profound knowledge. Lao Huo, who was squatting on the wardrobe and dozing off, suddenly croaked: "Little girl, don't brag." I know astronomy and geography, and I am well-known at home and abroad, so I will test you now, how about it?"

Miao Yue was unconvinced: "You ask!"

"Come on. Lao Huo shook his head and said: "A monkey riding on the tree, a monkey on the ground, how many monkeys are there?"

"Eight!"

"Wrong, it's two. It's a ride on a horse, a monkey ride in a tree......"

"You're a cheater......"

A crow flew over Lu Zheng's head, and the old fire even moved out Uncle Benshan's specialty math problems, which was simply too frustrating.

"Okay, that's just a joke for you. Now come to the real thing, you can hear me clearly. Lao Huo cleared his throat and said slowly: "There is a grove, and there are eight birds as handsome as this seat in a tree on the east side, and two birds flew away to the west, and three flew from the south, and one of the three that flew was male, and he went to the back and brought his four old friends." These four old friends are also with five birds, ask!"

"Eighteen!" the little girl reacted very quickly.

Lao Huo rolled his eyes and said, "I haven't asked you yet, what are you anxious about? Is this the attitude of doing learning?

"Ahem, listen up, ask, there are a few trees in this grove. ”

"Huh?"

Miaoyue's eyes widened suddenly.

Jixiang had already laughed.

Lao Huo said triumphantly: "Little girl, don't hurry up and come over to apprentice." ”

Miao Yue is not stupid, she quickly reacted, and said angrily: "You are cheating again, what kind of arithmetic problem is this." ”

As soon as the old fire played with treasure, the gods laughed and urinated. Lu Zheng held back a smile and said, "Okay, okay." Yue'er, don't worry about this owl, real mathematics, that's no less than the existence of the wordless heavenly book, even I can't figure it out. ”

"Won't it?"

Lu Zheng said honestly: "Really, I didn't pass at that time. The ancients had a saying that if you don't accumulate steps, you can't reach thousands of miles, and if you don't accumulate small streams, you can't become rivers and seas. So, if you want to figure out the ins and outs of this board, you'll have to start from scratch. ”

Letting Miao Yue go to school is not realistic at the moment. If you ask for a tutor, look at these birds, foxes, tigers, fish and other goblins around you, you don't need to ask if they are all scumbags.

Then you have to find another way, such as...... Professional teaching sites on the web. Fortunately, now that the Internet is developed, there are many such teaching websites, Lu Zheng chose a paid professional website, and immediately helped Miaoyue customize all the courses from elementary school to high school, and the price is very cheap, as long as ninety-nine-eight......

The little girl was dismissive at first, but she was soon attracted by the magical little experiment in physics, hugged the mobile phone and stopped talking, and concentrated on learning.

When I was busy with these, it was almost noon, and I had a simple lunch. Lu Zheng received a call from Lao Yuanshu, and the Daomen assembly will start tomorrow, but before that, there is a small sect gathering in Guifeng, Longhu Mountain, and all the sects with names and surnames will send people to participate.

Lu Zheng thought about it for a while and decided to join in the fun. (To be continued.) )
