In general, there are two sources of Dao Fruit. One is obtained through killing, and the other is through cultivation. The former's probability is too low; the higher the Dao Fruit level, the lower the chance of its condensation after death.
The latter's probability of obtaining Dao Fruit is much higher. As long as it's cultivated properly, it's almost certain to yield harvests.
There are various ways to cultivate Dao Fruit: some plant the Dao like farmers sowing seeds; some nurture the Dao like fishermen raising fish; some set up Spirit Gathering Arrays, gathering the mighty force of nature to condense into Dao Fruits... The methods are countless.
But in reality, there is a third type of Dao Fruit in this world.
There is a type of Dao Fruit that is naturally nurtured by heaven and earth, rooted in trees, requiring no human cultivation. It experiences the changes of seasons and can naturally bear fruit.
The Ancient Buddha Dao Fruit is one such instance.
