School has started, and my ex-boyfriend has graduated, and it is said that he really stays in xx hospital. Best friend Wang Xue and other former classmates have all been promoted to the fifth year. Tian Lingshuang is on her senior year. At the beginning of the school year, Tian Lingshuang took a big class, which caused a little sensation. Not for anything else, one is that she is now a beautiful little beauty, and the other is that her classmates found out that she was actually a senior sister who came down from the fifth year.

Most of the students were relatively simple, and originally thought that she had failed to repeat a grade with bad grades, but later inquired and found out that she was repeating her senior year because of illness. Most were kind to her. There are also classmates and seniors in the same grade from other departments who confessed to her that they wanted to make friends. Tian Lingshuang has no intention of having a boyfriend now, in addition to coping with her studies, improving her abilities is what she wants to do the most.

As for whether Chen Xi and Wang Yunfei found out that Tian Lingshuang was going to school, whether they had any malicious ideas brewing, Tian Lingshuang didn't care about it at all. To paraphrase what Wang Xue once persuaded her: Chen Xi and Wang Yunfei are not at the same level as her current self at all, and she has disdained revenge on them. Or, she should thank them even more, it was they who made Tian Lingshuang recognize the scumbag nature of her ex-boyfriend. Shouldn't you be glad to leave the scumbag?

The increase of Tian Lingshuang's ability can be said to be very fast, but it can also be said to be very slow. Soon it was because it only took her a month to quickly turn water into ice needles and ice arrows to penetrate foreign objects under the action of her mind. She thought it was because water and ice were just different forms of H2O at different temperatures, and the essence was the same, so she would be able to grasp it quickly.

It's slow because she wants to extract water from the air with her mind, and after a month, she only vaguely feels that there are some water molecules in the air, which are very active, but she can't extract them alive or dead. As written in the vertical and horizontal novel, as soon as the mind moves, a water balloon is formed in his hand, and Tian Lingshuang can't do it anyway. It stands to reason that water and gaseous water molecules are also different forms of H2O at different temperatures, so why is it not as easy as water to ice?

She "saw", or to be precise, felt that the water molecules were very active in the air, and whenever Tian Lingshuang concentrated on gathering them in the palm of her hand, the water molecules were like naughty elves, surrounding her, but they refused to listen to her "dispatch".

After another four months, Tian Lingshuang was able to penetrate two-centimeter-thick wood with water needles and water arrows, but he still couldn't extract water from the air. Tian Lingshuang was very frustrated. During this period, once, Wang Yunfei deliberately poured hot food on Tian Lingshuang in the cafeteria, Tian Lingshuang is now more sensitive than ordinary people, how can Wang Yunfei succeed, so Wang Yunfei poured the food on the secretary of the regiment in Tian Lingshuang's class.

The secretary of the regiment is a hot beauty, her family is rich and powerful, and although she usually does not deliberately bully her classmates, she is by no means easy to mess with. The makeup of the light green cashmere skirt on the body is worth a lot of money. It was stained with oil and salt, and it was estimated that it was wasted. Besides, the clothes may not be worth mentioning in the eyes of the regiment secretary, but she can't accept being embarrassed in public. Therefore, until Tian Lingshuang finished eating casually, Wang Yunfei was still crying and apologizing to the secretary of the regiment.

After this time, Tian Lingshuang didn't see Chen Xi Wang Yunfei again for a long time. After the final exams, the winter break arrived. Tian Lingshuang nests in her duplex luxury nest in Cuiwei Community every day, except for eating, sleeping and resting, she does nothing else, only practices her abilities.

On this day, she was able to control the ice needle to penetrate the thin steel plate. In addition to being happy, she practiced condensing water molecules from the air, and failed again! It was so frustrating, she lay down on the big bed, what was going on? What was the reason? Or was it because she wasn't a practitioner?

It occurred to her that the water in the cup, the water in the basin, and even the water in the rivers, lakes and seas was formed? Aren't they all water molecules? Why are they just the form of water? Instead of the water in the air, as she feels, it is just a small molecule?

When modern people have questions, the first time they have them is to search for answers on the Internet.

Tian Lingshuang picked up her mobile phone and began to check on the Internet. I found out, and it is said on the Internet that liquid water does not exist in the form of a single H2O molecule, but produces an association molecule through hydrogen bonding. The association of water is an exothermic process, so once the temperature rises, the degree of association of water decreases, and the water takes on a gaseous state.

When the temperature decreases, the association degree of H2O molecules increases, that is, it becomes water, and when it cools down, it becomes ice.

Each H2O molecule can form four hydrogen bonds with four other H2O molecules that are in close proximity. The most important thing is that Tian Lingshuang discovered this sentence: the conversion of ice and water did not break the hydrogen bonds, but only bent or twisted the hydrogen bonds.

However, most of the gaseous H2O molecules are single H2O, occasionally with dimer (H2O + H2O), and rarely have a form of more than trimer.
