The protagonist suddenly dies after staying up late and travels back in time. When he wakes up, he finds that he has become an ancient tree that is dying and is bound to the "National Destiny Feedback System". The system told him: when the empire's national fortunes are prosperous, the trees will live; when the national fortunes are declining, the trees will wither. At this time, the national luck index of the Great Yan Empire was only 23/100, and he had three days left to live.
In order to survive, he used his roots to secretly interfere with the court meeting and trip up the regent Xiao Xuance who wanted to kill him, while secretly helping the young emperor Chu Yunxi regain power. When Chi Yanguo invaded with the "Tree of Disaster", he used the body of the sacred tree to protect the country to fight against natural enemies, and used spiritual fruits to awaken the spiritual roots of the people across the country, ushering in an era of immortal cultivation for all. In the end, it is discovered that the regent is actually the reincarnation of the tree heart of the previous generation of sacred trees. He sacrifices his own memory and cultivation to lift the fatal curse of the ancient tree, and the protagonist completes the ultimate advancement and becomes the true sacred tree that protects the country.
This is a story about cultivating immortals and farming by traveling through Chengshu, relying on the fate of the country to survive, tripping up powerful officials in the court, and overcoming natural enemies on the battlefield. The protagonist's gesture of writing with branches is very handsome, and the way of eavesdropping on government affairs with his roots is very cool. As a tree, he finally became the faith that millions of people look up to.
