"Take this flower as an example, the reason why it is so red is because it contains pigments, which are called anthocyanins, and the anthocyanins are red, and the more acidic they are, the redder they are. Pen, fun, pavilion www. biquge。 info Anthocyanins appear blue when it is alkaline, and purple when it is neutral. ”

Zhou Tian naturally borrowed a text he learned when he was in junior high school on Earth, that is, "Why Are Flowers So Red" by Jia Zuzhang.

He didn't want to think about whether Xiaoqin could understand, mainly because he still maintained some habits on the earth, because Zhou Tian read a lot of miscellaneous books, for example, when someone asked him why, he gave you a word or two, to help you popularize science, "Since you asked sincerely, then I will tell you compassionately", as an extreme science and engineering man, Zhou Tian felt that it was his responsibility to eliminate ignorance, even if the other party was his boss.

So on Sundays, I repeatedly hit a wall at work, no boss wants to listen to you too much, life is unsatisfactory everywhere, and no friends are willing to listen to you too much. Zhou Tian is too upright.

Zhou Tian gradually understood that when you have enough power, power and reputation, what you say will be carefully listened to and studied even if it is nonsense, and when you have nothing, you have to learn to be tactful, and you have to bow your head when you should bow your head.

In the period before the crossing, Zhou Tian learned to keep a low profile, talk less, and do more.

In the past few days, Zhou Tian has been asked by Yingying Yanyan's maids and girls, and the dusty room in his mind has been opened again.

"So, the new colors of roses can be cultivated over and over again, and there are many uncertain ones. Red roses represent passionate and true love, yellow roses represent precious blessings, purple roses represent romantic and true feelings, and white roses represent pure and innocent ......"

These celeries understood, and their faces turned even redder, as if they could squeeze out blood.

In the past few days, Zhou Tian will run to the Huangshi Mountain Range a few times, not to find guilt, but to pick dragon grass, unripe dragon grass is relatively easy to find, it doesn't matter if it is not ripe, because when Zhou Tian absorbed the dragon grass that was knocked down, he found that no matter how manic the energy was stored and released, it would become extremely gentle, probably through the transformation of the heart of the project.

However, Zhou Tian also picked and absorbed the positive energy of some other medicinal herbs. At this time, if the positive energy stored in Zhou Tian's body is absorbed, it is estimated that it can increase the activation progress by 5%. Because of the frenzied picking on Sunday, the price of positive medicinal materials and pills on the market has risen for a period of time.

"Fang Zheng and Uncle Tong should be better, go and take a look, and go to Fang Lin to talk about those two things by the way. "On the street, a roast chicken on the left and a big bag of roast beef on the right are eating and walking on the road. In order to activate the system as soon as possible, Zhou Tian didn't care about any image. It turned out that the part of the energy that was not activated to refine Zhou Tian's body had already consumed about half, and there was still 25% left.

Now Zhou Tian has ordered Xiao Gong to no longer use these energies to refine his body, but to activate them, "The current activation progress is 92%. ”

When is it the hardest, some people say that it is the hardest time when the download progress bar of low-cost love action movies stays at 99%.

Success is just around the corner, Zhou Tian is now anxious, very difficult, in order to catch up with the schedule, he is eating all the time.

By the window on the second floor of a restaurant on the street, two teenagers were building spiritual tea and eating exquisite dim sum, with elegant movements and slow movements.

Lin Hua wiped his mouth lightly with a handkerchief, "Brother, what do you think of him." ”

"A martial artist, not enough. The person across the table said lightly.

"Oh, I've seen him use vajra to fend off my men's swords and arrows. Lin Hua became interested.

"There is no aura fluctuation on his body, maybe he used a talisman. ”

In this way, the Fang family is not afraid. The only thing he needs to take care of is to find a chance to return his life-saving grace. In this way, my trial task is almost complete, and I can prepare to go back, and it will be five years in the blink of an eye.

Lin Hua thought about it while reminiscing, and his fingers tapped lightly on the table, dada, there seemed to be a special rhythm in it, which made people not feel upset, but felt peaceful.

"Brother, I have always felt that your talent is better than mine, there are many things you taught me, without you I may not be able to enter the Bafang Gate, and I know that you also have spiritual roots, why don't you join the Bafang Gate with me? This is a chance to seek immortality?"

"Immortality? Immortality is too long. Lin Hua didn't answer directly, now is not the time, let's wait until the family trial task is completed.

In the firewood room of the Fang family, Fang with a white cloth belt tied to his chest was chopping wood, carrying water, and lighting a fire, the white cloth on his chest was constantly oozing blood, Fang Zheng did not make a painful sound, gritting his teeth and his forehead was covered with cold sweat.

With a snap, Fang Zheng suddenly felt that his eyes were black, and he was a little unable to exert his strength, and the axe in his hand to chop wood was unstable, and he accidentally flew into the pyre in front of him.

Zhou Tianzheng outside the door wanted to go in to help. At this time—

"Waste, you can't chop wood, what if you throw an axe at Madame, what's the use of you, if you blame it, watch your head. The butler, who was watching from the sidelines, scolded with a hideous face.

Turning around, there was another face, and he said flatteringly to the lady sitting there: "Mrs. Pan, I will keep an eye on him here, and I will call you as soon as I boil the water." You don't have to get your eyes dirty here. ”

Mrs. Pan was wearing a long red dress, her breasts were half-hidden, her temples were towering, her eyebrows were like light smoke, and her body was light and charming, "Butler, you and I have been here for almost five years, and you also know that since the old man was hit by cold poison five years ago, he has not been better yet, and an immortal who is good at medicine has come to see it, and it has only temporarily delayed the symptoms of the old man." Before leaving, the immortal said that if there were enough positive herbs, long-term use might be improved, and if you wanted to be completely good, you still had to use dragon grass. ”

Mrs. Pan stretched out her slender jade hand and opened the medicine box she brought, and there was a memory of Longyang Grass lying inside: "How rare is mature dragon grass, only this Longyang grass is easy to obtain in the past few years." ”

"In the past few years, madam, you have been helping to cultivate Longyang grass despite your hard work, and it is not easy to serve the master to take a bath with Longyang grass, and it is also appropriate for the master to favor Mrs. so much. The butler nodded beside him and patted his ass.

Zhou Tian outside the door had a strange look, and now Zhou Tian is no longer the original Wuxia Ameng, and he still understands some common sense.

Longyang grass, to put it bluntly, is to use the blood of the male demon beast in the prime of life when he was in estrus but did not mate to water some high-quality sprout grass.

This is not difficult to obtain at all, but if you want to get pure Longyang grass, you have to cultivate it yourself. It's just that very few people grow it openly, after all, this is the material for making aphrodisiacs. It's not good to spread out, a huge family, actually planting this kind of thing at home, it's not good for reputation. No wonder that lady should be served, the kind of lust that burns with Longyang grass is not something that ordinary people can bear.

Zhou Tian remembered the day when he accidentally ate Longyang grass in the Huangshi Mountain Range, but fortunately he only took a small bite, otherwise it would not be as simple as not being able to sleep that day, because Zhou Tian was already strong, and Longyang grass was simply adding fuel to the fire.

Zhou Tianhuangshi Mountain Range's experience of tasting herbs and told him that this Fang's Longyang grass seems to be impure, and Longyang grass impurity is very common in Huangshi Mountain Range, because the blood of demon beasts in estrus that has mated is sprinkled on the bud grass does have this situation.

If he is not completely positive, although it looks like there is no difference when he takes it, the impure Dragon Yang Grass has no effect on ordinary people, and the yin qi in it will be neutralized by sufficient blood qi. But if it is a person who has been poisoned by cold and uses such a dragon yang grass, I am afraid that it will continue to accumulate into yin poison in the body, and when taking a bath, he will do that kind of pleasure for men and women. It's like an old birthday star hanging.

Could it be that the old man didn't know about this? There is this possibility, because the yin qi of the Longyang Grass is not easy to detect, and the appearance of the pure and impure Longyang Grass is the same, and it cannot be seen. His body is getting worse day by day, and he may think that it is caused by the cold poison before, and the yin qi has accumulated for five years, and it seems that he will not live long.

Zhou Tian glanced at the Mrs. Pan deeply, originally Zhou Tian wanted to go out and say that he had a way to cure this cold poison, but it seemed that he still had to discuss it with Uncle Tong.

After Zhou Tian turned to leave, Mrs. Pan showed a charming smile, "It seems that the little brother is gone." "It's been five years, and it's time to end. The housekeeper looked emotional, not at all without the appearance of slapping the horse just now. Fang Zheng, who was chopping wood, was already unconscious on the ground.

Under the leadership of the household servant, Zhou Tian came to the Fang family's living room for the first time, Fang Yun, the head of the Fang family, Uncle Tong Fang Tong, and the young master Fang Lin were all sitting here, as if waiting for his arrival.

"Little brother Zhoutian, where are you in the afternoon these days? You think about it carefully, and then explain it to my eldest brother Fang Yun. Uncle Tong said seriously. The head of the Fang Yun family sat in a high position, staring at Zhou Tian coldly.

What happened? Zhou Tian didn't understand for a while, and replied truthfully: "I've been collecting medicine in the Huangshi Mountains these days. ”

"What kind of medicine?"

"Some Positive Spirit Grass ......"

"Hmph!" Fang Yun smashed the stone table beside him with one palm, and shouted, "Even if you are kind to our Fang family, what kind of grievance do we have with you, why do we harm our Fang family?"

Zhou Tian frowned, he was not very happy, I have been running around to save you in the past few days, you say that I will harm your Fang family? Zhou Tian looked at Fang Lin who was sitting on the side, Fang Lin lowered his head nervously, his hands were clasped, and he couldn't give him any information.

"Sister-in-law Pan said, she found that in the past few days, you have been kind to our Fang family, not only teasing our Fang family's maids, but also secretly using the impure Longyang grass picked by the Huangshi Mountain Range to mix it with our Fang family's pure-blooded Longyang grass, which has made my eldest brother's condition worse in the past few days. Why are you doing this?" Uncle Tong said in a disappointed tone.
