After communicating with the Red Tide, in the perception of the Red Tide, the heaven and earth are colorful. These colorful things are different qi. These qi are the foundation of all things, and all things will emit various qi outward.

This made Zhang Ying have many speculations. As a time traveler, although he was a poor student in his previous life, it did not mean that he was stupid, he was just not good at exam-oriented education. On the contrary, he liked reading very much, and these books were not limited to novels... Through some popular science books and baptism of science fiction novels, he knew that there was a theory of quantum mechanics called "matter waves".

According to his understanding that he seems to understand but not understand, it seems that everything can be regarded as a kind of wave. If this understanding is based on this understanding, is this "qi" a "wave"? Zhang Ying thought about it for a moment, and his mind was filled with mud. This was beyond his understanding. He himself was a person who was half-understanding. Why do he think about this?

He shook the messy thoughts in his mind, and instead considered what to choose from the third type of "golden energy".

Is it the 'gold energy' or the 'xin metal energy'? Is it the 'copper and zinc energy' or the 'copper and tin energy'?

Thinking of this, Zhang Ying couldn't help but touch Chi Chao's tiger's head. Chi Chao's first evolution was to use copper-tin alloys. Should we absorb the "copper-tin energy"?

The copper and tin gas is the bronze gas! Bronze is originally refined from copper and tin. If there is no stable gas production like Yinshan, the effect of absorbing any gas is similar, because the content between heaven and earth is similar.

Since this is the case, Zhang Ying decided to choose bronze energy. In this way, there are three types of "gold energy" that Red Tide can absorb, namely "Gengjin energy", "Silver energy" and "Bronze energy".

After choosing, continue practicing before dawn.

When it was dawn, Zhang Ying stopped practicing and came outside to collect cloudy air and draw silk. After the morning glow, he swallowed a fasting pill and went to the library to take up his post.

The library looks like a three-story building, but there is actually a lot of space underground. The entire Huju Temple is built on the top of the mountain, but the entire mountain has been hollowed out.

The three-story building is a place to receive disciples, and some random miscellaneous books are also placed in the small building. However, few disciples have the leisure to read leisure books in the small building. They are also very busy in their practice.

He casually grabbed the ghost servant in the library and asked for directions. Soon the ghost servant took Zhang Ying to find Mu Qingli.

Mu Qingli is a female cultivator, with a tiger as big as a puppy. It seems that female cultivators like small black tigers. Xu Yinlian is also a kitten-sized black tiger. When she saw this female cultivator, she was operating a small tornado to play with the little tiger. The small tornado is only half a meter high and constantly wandering on the ground, while the little tiger is chasing the tornado.

Seeing the little tiger trying to chase but couldn't catch up, the girl laughed like a silver bell.

Not long after, the girl also discovered Zhang Ying. Then she hurriedly removed the tornado and said to Zhang Ying a little embarrassedly: "Is this senior brother here to exchange spells?" Her job is to exchange spells for her disciples, but because this job is very leisurely, she often is not on duty, but is outside playing with tigers.

"No! My name is Zhang Ying, and it was Master Elder Qu Ji who asked me to come to find you!" Zhang Ying shook his head.

"Oh! So it's Junior Brother Zhang!" She shouted exaggeratedly, then bowed and apologized, "Sorry, I should pick you up! I forgot!"

Zhang Ying was speechless for a while. Senior sister, are you serious? Can you forget this? You are a monk, without forgetting.

Mu Qingli sent her little tiger away and came to Zhang Ying and said, "The elder has sent me a message and asked me to bring my junior brother to familiarize myself with the environment. Come with me!"

She took Zhang Ying back to the small building and then introduced: "There are formations inside and outside the library. This is the place where inheritance is recorded, so there is no way to avoid any mistakes. There are also senior brothers who are guarding each other in the secret, but they basically do not show up."

"The three levels here are all miscellaneous books from outside, and there are no magic. The care of these books is given to the ghost servants, so we don't have to worry about them."

As she said, several ghost servants who were sorting out books hurriedly knelt down and hurriedly hurriedly avoided them. These ghost servants didn't have much work, just to prevent the books from getting damaged or moldy.

As Mu Qingli said, he took Zhang Ying to an underground entrance.

"There is the storage place for magic and classics here. Only people from the library can enter. Now you and I can enter. I am responsible for exchanging magic for my senior brothers, and you are walking, you have this right."

As she said, she pushed open the downward door. "Don't look at this door without a lock, it actually has a magic circle that senses the token on our body. If you don't bring a token, this door cannot be opened! So you must remember to bring a token. Moreover, the magic circle has the function of identifying people, and the token and the human aura cannot enter even if it does not match the token."

When you enter the ground, you will see a long and winding passage. Next to the passage are wooden doors, with words engraved on them.

"This is the place where spells are stored. Don't look at the many rooms, in fact, there are only one or two magics in many rooms, and some rooms are still empty." Mu Qingli complained: "It's so annoying that so many rooms are, and I'm still responsible for cleaning here, and I have to clean the empty rooms!"

As she said that, she pushed her hand gently, and a breeze blew up in the passage, gathering together the small amount of dust in the passage.

"Senior sister just use this spell to clean it?" Zhang Yingqi said.

"What about that? Do you need to use your hands if you have magic?" asked the senior sister. This left Zhang Ying speechless.

"The spells in the room were originally not allowed to be taken out. If a senior brother exchanged the spells, he could only give them a copy." The senior sister said as she walked. Soon they reached the end of the passage.

At the end of the passage is a room locked by an iron door. Mu Qingli said: "We can't get into this room. What exists is the magic and classics of the Foundation Establishment Period, which are managed by the elders themselves."

She turned around and said to Zhang Ying, "This is the case in this library. She is not busy with work. She just can't practice in her spare time. She is surrounded by a large array and her practice is more full than outside!"

Zhang Ying nodded and asked her senior sister a little curiously: "Senior sister seems to be very familiar with the library. Have you worked here for a long time?"

Speaking of this, Mu Qingli was a little angry: "That's not! I've been taking turns here for five times!" She stretched out her palm and gestured to show off a 'five'. Zhang Ying was stunned and said, "Didn't she say she can't take turns in the same place for a long time?"

"I also asked the senior brother in the exam room this way. What do you think of that senior brother?" Mu Qingli said angrily.

"What do you say?" Zhang Ying supported the role.

"He said that Elder Qu Ji liked my work attitude very much, and the 'Hufeng technique' I learned was the best for cleaning! Listen, is this what people say?" Mu Qingli became even more angry!

Zhang Yingqiang held back the smile on his face. He suddenly thought that his senior sister had just done a good job of cleaning Hufeng just now.

"The rotation here has delayed my practice!" Mu Qingli said unhappily.

"I am slow in my practice. It took me a year from sensing qi to practicing qi. I was not talented enough and I would be delayed in my practice." She paused and asked Zhang Ying with some curiosity: "How long did it take you to go from sensing qi to practicing qi?"

She looked at Zhang Ying with bright eyes, looking a little expectant. Zhang Ying said guiltily: "About eight months?"

Hearing Zhang Ying's answer, Mu Qingli's face suddenly collapsed: "Sure enough, do I really have no talent?" She said deflatedly: "When I first chose qi, I chose 'mu Qi'. Later I found that 'mu Qi' was really difficult!"

"Later, a senior brother said to me, 'Since you have chosen the Wood Qi, then the Xuanhu will follow the path of the Water Tiger. In the future, the Wood Qi and the Water Tiger will have the effect of water and wood prosperity. Since you choose the Water Tiger, then choose the Wind Skill, which will have the effect of prosperity and prosperity in the future'."

"I just believed it stupidly. Now my practice speed is not fast, because my realm is too low, and the effect of water and wood is too poor can't be seen. Because my practice is too low, the magic effect of Fengshengshui cannot be reflected. It's too difficult for me!"

The senior sister said frustrated, and Zhang Ying listened speechlessly. It seems that the senior sister is following the route of the late stage, and all this requires cultivation to be guaranteed. Now the senior sister is only at the fourth level of Qi training, and many things cannot be reflected.

Zhang Ying could only comfort her and said, "Senior sister, don't worry, when your cultivation level rises, everything will improve."

She nodded and said, "I thought so at first, but later that senior brother failed to attack the foundation building stage and was struck to death by lightning." Zhang Ying opened her mouth, is there any necessary connection between the two?

"Only the liars will be struck by lightning..." said the senior sister quietly. Zhang Ying suddenly felt cold on her back and smiled embarrassedly and did not dare to speak. It was unwise to explain at this time.

"Since this is the case, the master should also give you some subsidies, otherwise it will be too unfair to you." Since the master wants his senior sister to work here, it will delay his senior sister's cultivation, and in theory, he will have to compensate him, otherwise the senior sister will be too pitiful.

"Actually, there are!" When I said this, my senior sister felt a little embarrassed. "It's just that I bought the compensation Pill of the Vital Qi Pill, the Pearl Whitening Pill, and the Black Wire Long Hair Pill!"

Senior sister, how much you love beauty! No wonder you can’t improve your cultivation. Zhang Ying is too lazy to complain.

She was embarrassed, so she stubbornly changed the topic: "Okay, okay. It's dark here, let's go!" After that, she pulled Zhang Ying away from the underground.

Back at the small building, Zhang Ying saw the cleaner tremblingly, huddling in the corner like a quail. When he was wondering, he saw Uncle Shi floating in front of him.

"Uncle Shi! Why are you free to come here?" Zhang Ying asked subconsciously, and then suddenly realized that it must be the master who came!

Sure enough, Qu Ji sat on the chair and flipped through the spell exchange registration book. Mu Qingli was shocked and immediately trotted up to stay by his side, saying hello weakly.
