The heritage records in the Ten Thousand Books Tower state that these few top-notch Buddhist laws lead directly to the supreme Buddha; if one reaches Mahayana, they might even ascend to the Pure Land Heaven.
However, with his current level of access, he could only browse through inheritances that can be cultivated to a level comparable to the Hollow Void Realm.
The Maha Bodhi Heavenly Sutra was passed down to the orthodox Buddha Gate of the Buddha Realm and is one of the supreme Buddhist Dao inheritances of the Buddha Gate.
Only the successive generations of Buddha's children could inherit and practice it.
But for Su Yu, the downside of this Buddhist law was that it was too orthodox, requiring a Buddha's heart to unleash the power of this Buddhist law.
And a Buddha's heart, Su Yu clearly did not possess.
Even if he used the proficiency panel to cultivate it to Mahayana, it wouldn't be very useful.
