THE NEW KNOWLEDGE

Now, Zhu Su's botanical garden had been half-filled, the amount of the plants had increased more than before. One by one, the members of Team of Wellbeing had returned from their search, as well as other messengers. Trees and green grass filled the whole garden. Sometimes they could inhale the pollen powder incidentally crossed the air. The various flowers made the garden significantly more colorful. Green, red, orange, white, blue, purple... What beautiful scenery, like a paradise in heaven.

And, among the dense trees, flowers, and leaves, some new sprouts emerged. These shoots impaired the beauty of the garden, making it not as perfect as the hope of those who were only looking for beauty. However, for Zhu Su, it was the contrary case. These shoots were the most incredible stuff. His intention was to see the growth of a plant from its beginning. How did it look like when it emerged from the ground, how did it appear when it grew, until it finally became a mature plant, ready to bear fruit. How about the shape of the roots, the shapes of the leaves, the shapes of the flowers, the shapes of the fruits...

Everything about plants, he wanted to research it.

Even including its peculiar movements.

Yes! Apparently, plants can move! Such a big mistake to say that only humans and animals can move. Plants can move too, although only a few specific plants can do it. Zhu Su was also shocked as he figured it out. Moreover, the time when it moved was the same astonishing - it moved in the evening.

"What a beautiful flower." Hu Nayin was looking at a conspicuous pink flower. It had a white base, and its stamen was pink. The flower-shaped different from the most flowers which usually possessed large crowns; its crown was like thin and smooth tassels, soft like silk. She then held the flower, and fell silent for a few moments.

"What kind of feeling do you get when you hold it, Your Highness?" Standing beside her, Du Qinfeng asked. Du Qinfeng was the fastest one who got closer to them among the experts Liu Ku and Shao Rong brought.

Hu Nayin smiled. Her smile looked mild, and warm. "This flower makes me feel contented. I feel very peaceful and serene, all problems can be forgotten in an instant. As if... I don't want to turn away from it..."

"But this flower also smells good. Its fragrance can tranquilize mind." Zhu Su commented on. He observed the flower more thoroughly. "Ah... if I'm not mistaken... is it Hehuanhua (the flower of Persian silk tree/pink silk tree)? The flower which can treat psychological disorders..."

"Yes, Your Highness." Guo Songmi replied. During Pu Ji Fang's writing process, he was the writer of the part that discussed Hehuanhua. "This flower is especially good at treating psychological disorders such as anxiety, agitation, stress, insomnia, shortness of breath due to fatigue, but it can also treat traumatic injury and lung abscess."

"And the legend about it is as beautiful and attractive as the flower itself," Du Qinfeng added. "Do you know that this Hehuanshu (pink silk tree) is nicknamed the Tree of Ghost?"

"Tree of Ghost?..."

"If there are family members or anyone who die in less than seven days, Hehuanshu can help us meet the spirits. We just have to stand under the Hehuanshu at Zi time (11 pm to 1 am) by holding Hehuanhua, then we will be able to see the spirit at issue."

It was evening now. The evening wind began to blow. Hu Nayin could not withstand the cold which suddenly spread through her body, she shivered. Seeing the Wang Fei got afraid, Du Qinfeng laughed, quickly calmed her down, "Your Highness, please don't be afraid. Apart from having mystical myths, Hehuanhua also has a very romantic legend. A heart-touching love story."

"Really? What is it?"

"This flower is called Hehuan * , because it is taken from the name of a girl whose myth ever lived. Hehuan was the wife of a Xiucai, she was very beautiful. The Xiucai also loved her very much. They had two children, boy and girl. Hm, at first glance her life sounds perfect, huh? But since her childhood, Hehuan had been sickly. And she could not live a long life. Actually, she dreamt to live with her family until she grew old, to see her children grew up and got married and had a family... poor Hehuan, her dream didn't come true. Hehuan died young. But the myth said, she didn't want to be reborn, she wanted to keep staying in this world, together with her husband and children. Finally, she transformed into the Hehuanshu. It was said that every night Hehuan would come out of the tree to see her husband and children. This is another legend why Hehuan is called Tree of Ghost."

"Hmm, even though it still contains mystical aura... but you are right. This story is really touching." Hu Nayin clasped her hands in front of her chest. "Somehow I can feel Hehuan's grief, as well as her great love for her husband and children."

The evening wind blew again, but this time it was like bringing heart-rending music.

The dusk was getting dimmer and dimmer. The sun glowed reddishly, almost set behind the horizon. Suddenly, Zhu Su's eyes captured something. He gasped.

"Hehuan leaves... are moving!..."

Everyone immediately focused on Hehuan leaves. The leaves did move! The movement was very slow, but it was still visible. The leaves which were wide open, slowly began to close.

"Hehuan leaves are closing! Incredible!" Hu Nayin could not hide her surprise.

Guo Songmi's brows knotted. "Is this the move that makes Hehuan get the nickname of Tree of Ghost? Because the leaves will close at night?..."

"Oh, no. In our sect, Hehuan is called Yehe, which means The Tree which Closes at Night. It also has another name, Hehun - Closing up at Dusk," Shao Rong said.

"That's right, it doesn't sound good if we keep calling Hehuan as the Tree of Ghost," Zhu Su expressed his opinion.

"After all, the myth of Hehuan is a beautiful, heartwarming story. I agree with His Highness, we should give it a beautiful name," Hu Nayin said.

Now the sun has completely disappeared from sight. The Goddess of the Night had been ruling over the earth. The stars twinkled. In the darkness, all of He Huan leaves closed. As if they wanted to sleep, rested in the night lullaby.

"Ah, such an interesting fact. It should be noted." Zhu Su took out a small notebook and stationery from his small bag, then wrote down the facts he just discovered about Hehuan.

...

* Hehuan is the original name of the plant. Hua means flower in Chinese, while Shu means tree.
