Zhang Hao returned to Zhang's house late at night, but he didn't care about resting, so he went to the dock to inspect.

Half a year has passed, and the Ocean Group has built a total of 40 warships, and now the fifth batch of 10 warships has entered the outfitting stage. It is expected that it will take up to 20 days to go to sea.

But what Zhang Hao came to inspect today was not another warship, but a giant ship in the largest dock, which is also nearing the end - a super battleship with a length of 270 meters and a design displacement of 35,000 tons!

The madness of industry is vividly displayed here. Profiles produced from the Rancishan Gentetsu Factory and the Iron and Steel Factory were transported here by two parallel trains.

A deck of more than 8 meters wide and 15 meters long can only be transported by two parallel locomotives.

At this time, there are still pieces of ship boards delivered, and the cranes at high places, and even the gantry cranes, are constantly moving. I-beams, pieces of steel plates, etc., are neatly stacked in the warehouse location.

From time to time, craftsmen can be seen transporting materials, parts, tools, etc. through spells, and the scene is busy. At present, this battleship has been under construction for half a year. From the successful research of '20,000 tons', we have been studying 30,000 tons until today. Now, it has entered the outfitting process.

But what attracted Zhang Hao the most at the scene was welding. Now, the welding technology has been preliminarily matured. The new battleship no longer uses a rivet structure, not a single rivet, all of them are welded.

Because of the maturity of welding technology, there are now super warships. The design of a displacement of 35,000 tons is a brave and crazy attempt! That is, the cost of steel in the Zhang family is actually very low, otherwise they would not dare to make such an attempt.

Zhang Hao looked here for a while, and after understanding the situation, he once again determined that he would be able to officially go to the sea in about 20 days, and Zhang Hao smiled with satisfaction. Twenty days later, it happened to be north to explore Liuli Island and related routes.

Leaving the dock, Zhang Haocai returned to the residential area. But I saw Zhou Xueyao's research room from afar, and the lights were bright.

Zhang Hao's footsteps paused slightly, and he turned to walk towards the research room. But seeing that everyone was not resting, even some children were excited not to sleep, yawning, but also running around excitedly.

Zhang Hao was puzzled, and walked to the front of the building, but saw Xiaozhu, the maid beside Zhou Xueyao, running excitedly: "Uncle, you came just right." Mademoiselle has discovered isotopes and has already made a preliminary refinement of the periodic table.

Just today during the day...... Ah, it was yesterday during the day, and Miss deduced a brand new metal element according to the periodic table, which turned out to be a high-purity spiritual material, a spiritual material that we didn't know about in the past. And we're in the lab, and we've refined it!

This spiritual material is very light, almost half the size of the dark iron.

According to tests and calculations, this metal is widely found in the soil and contains far more than iron. Moreover, as long as this metal is refined, it is a spiritual material, and it does not need to be further smelted and purified like dark iron! It is somewhat similar to gold, silver and copper. ”

Zhang Hao's footsteps suddenly stopped. This thing...... Not to mention, if Zhang Hao remembers correctly, aluminum has one more neutron than proton, and the isotopes of aluminum in nature are very rare and almost negligible.

Thinking of this, Zhang Hao asked, "Is this a silvery-white, but darker metal, if you don't treat it, it's very soft, but it's a little harder than lead." ”

"That's right!" Xiaozhu shouted excitedly, suddenly stopped, and looked at Zhang Hao suspiciously, "Uncle, how do you know?"

"I guess, haha...... You think, it's lighter than iron, it should be soft......"

"But silver is much heavier and softer than iron?"

Zhang Hao: ......

When Zhang Hao met Zhou Xueyao, Zhou Xueyao was discussing the periodic table with everyone, and there were Wang Xuefeng and other elites of the Zhang family. Not only that, but Fu Yun's disciple, Ge Dong, also joined here.

Everyone discussed very fiercely, on the table in front of Zhou Xueyao, there were several pieces of silver-white metal of different sizes and irregularities, but the surface of this metal was slightly dull, and there was obviously no luster of silver.

Seeing Zhang Hao come in, Zhou Xueyao's face flashed with bright joy, but she sat behind the table and did not move—the discussion was very heated now, and what was being discussed was the naming of this new metal.

After Zhang Hao sat down, he listened for a while, then said twice and stood up, "I have an idea." What we have discovered now is a completely new metal, so we should create new 'words' to name it.

At present, we have found that there are three main categories of elements.

Metals, gases, and non-metals that are also non-gases.

Therefore, I want to make words like this: metal elements, and make words with 'gold characters'. We can borrow the names of copper, silver, lead, steel. Non-metals are named after 'next to the stone character'. For example, carbon, sulfur, phosphorus, etc. gas, directly with 'gas' as the radical. Such as 'oxygen', 'nitrogen', etc., which we have already named.

At present, this new gold number, sorted by 13 bits in the periodic table, is spelled according to the phonetic alphabet, similar to the pronunciation of 'Lu', so let's name it 'aluminum'!"

Zhang Hao said as he used a spell to condense the word 'aluminum'.

Zhou Xueyao looked at the "character pinyin" on the periodic table, and the corners of her mouth picked slightly, the character pinyin pronunciation of the No. 13 element is similar to the "fall" sound, which is very different from the "Lu" sound.

It is said that Zhou Xueyao compiled a set of character pinyin with text deviations, formation symbols, ruler notation symbols, etc., and now this character pinyin has been widely used in the education of Beidou Academy.

The periodic table, on the other hand, is represented by the repeated superposition of symbols, similar to the superposition of 'heavenly stems and earthly branches'. In this way, each element symbol has at least two characters in pinyin, which can spell about one pronunciation.

But the pronunciation of 'aluminum' is too different, right?

Zhang Hao saw Zhou Xueyao's expression and immediately sent a bright smile - obsessive-compulsive disorder. In other words, if this element is not named 'aluminum', I am not familiar with it by another name.

The name was finally decided, but everyone did not rest, but wanted to continue to discuss and standardize the refining process of aluminum, and strive to be able to produce it industrially.

"Okay, okay!" Zhang Hao got up, "Everyone, I am very happy that you can work so hard to sleep and eat, but I am also very worried. Ladies and gentlemen, you need to take a little time to practice, and you need to take a little time to calm yourself.

We have a lot more to study, and the periodic table may be just the beginning.

For example, what are the elements made of? Can we artificially create elements that do not exist in nature?

If you want to explore the deepest secrets of this world, all you need is to rest well, practice well, and strive to be able to break through the Divine Transformation Stage and have thousands of years of research time!

Instead of staying up late here. ”

Ge Dong has an opinion: "But...... We want to ......"

"Rest, you've got a lot of things you want. Look at what you have all boiled into, all of you have dark circles under your eyes, and you are fluttering when you walk.

Let's take a day off tomorrow and everyone have a good rest. If you're tired, you'll have to stare dryly if you want to study in the future. ”

After speaking, Zhang Hao stepped forward and pulled Zhou Xueyao away, Zhou Xueyao's face was blushing: Zhang Hao, are you really thinking about everyone?

An hour later, Zhang Hao hugged Zhou Xueyao's soft body and smiled proudly. Zhou Xueyao pinched Zhang Hao a few times angrily before asking angrily: "The pronunciation of the No. 13 element is obviously not 'Lu', but you skillfully sketch the word 'aluminum'." Say, do you know anything?"

Zhang Hao looked at Zhou Xueyao in surprise, he really didn't expect this woman to be so careful. But Zhang Hao won't answer this question...... It wasn't until dawn that Zhou Xueyao fell asleep softly on Zhang Hao's body.

It wasn't until noon that Zhang Hao got up. According to the plan, today there should be a return of the fleet of the Southern Airlines.

Since the eradication of mirages and sharks along the way, the fleet has never encountered a crisis again. On the sea, it seems that calm has returned. Since then, with the production of more and more warships by the Ocean Group, the sea routes have become more and more busy.

However, today's fleet is a fleet that communicates with the Heavenly Demon Sect, and this is the third and largest exchange between the Ocean Group and the Heavenly Demon Sect.

The fleet refueled at Skull Harbor before moving on, news from the previous fleet.

Sure enough, in the evening the fleet returned. Three Zhenyuan-class warships and five Iron Duke-class warships appeared in the harbor.

However, Zhang Hao saw at a glance that there was an acquaintance in the bow of the battleship:

Red Lotus Sect Left Protector, Flower Herb!

"Why is this old lady here?" Zhang Hao instantly felt a little numb on his scalp.
