If you concordance is a strong's it only deals with words in the KJV, try using a lexicon. Here's how the ESV translates it John 20:17 "Jesus said to her, “Do not cling to me, for I have not yet ascended to the Father; but go to my brothers and say to them, ‘I am ascending to my Father and your Father, to my God and your God"
Also notice that it translates ascend to ascending, does it mean that He ascended twice? No. It simply mean that He was going to ascend to the Father, which He did in Acts 1:9
As far as the idea that He needs to place His blood on the mercy seat goes against Scripture. Hebrews 9:13-14 "For if the blood of goats and bulls, and the sprinkling of defiled persons with the ashes of a heifer, sanctify for the purification of the flesh,14 how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God."
His blood was offered by the Holy Spirit.
