Jade case (Chu Yao)

He slowly opened the jade case. Inside, there was a verdant leaf that looked almost crystalline. It emitted boundless life energy.
The entire room became filled with life energy. The potted plants Meng Qi had placed in Long Chen's room all began to rapidly grow as they overflowed with vitality.
"The Dragon swims across the four oceans; the Phoenix flies throughout the nine lands. Seas of blood may block us, but we will never give up our path; Dragon and Phoenix will both live to old age."
These four lines were on the leaf. This was the promise the two of them had made to each other during the Phoenix Cry Lantern Festival.
The first two lines were what Chu Yao had summoned the courage to say to express her life for Long Chen while she was stuck in an inescapable cage.
The last two lines were what Long Chen had sworn in front of all the experts of the capital. Although they contained some of the frivolity of youth, the two of them truly loved each other. Seeing these words, Long Chen's tears almost overflowed.
These words were not written on the leaf. Instead, they were the result of the natural vein lines on the leaf. In other words, they had formed when this leaf was born. Although Long Chen didn't know how Chu Yao had managed to do this, just from this small leaf, he could feel how much Chu Yao missed him and her heartfelt feelings.

This leaf contained a familiar aura. That was an aura he had felt from Pill Valley's Pill Fairy, as well as the Illusory Music Immortal Palace's Zi Yan. At the same time, he thought of four dislikeable figures that had appeared in the Immemorial Path. When Yue Xiaoqian was about to pass her tribulation, those four idiots had almost caused her to be killed by her tribulation.
In his fury, Long Chen had provoked the Heavenly Daos and brought down heavenly punishment. That had ruined those four's tribulations and scared them off. 
Long Chen wonders if those four idiots were also that level.
He felt boundless life energy from this leaf, as well as boundless Heavenly Dao energy. Although it was just a single leaf, it seemed to represent the will of the heavens. Its existence broke all the laws around it.
