I now found some discrepancy in my understanding of New Testament and blood of Christ:

(Mt. 26:27-28) “27 He took the cup, gave thanks, and gave to them, saying, “All of you drink it, 28 for this is my blood of the new covenant, which is poured out for many for the remission of sins.”

(Mr. 14:23-24) “23 He took the cup, and when he had given thanks, he gave to them. They all drank of it. 24 He said to them, “This is my blood of the new covenant, which is poured out for many.”

How can this be blood of new covenant before the blood of Christ was poured out, “baptized” the underground waters of the Earth and entered into vine plants for us to be able to take Eucharist?

Hope to hear your answers.
