Ye Jun had accumulated quite a few Mysterious Techniques, but many were simply useless to him. Some because of low ranks, others simply because he didn't have Dao Affinity of them.
Naturally, he could have collected them but he was still afraid of the changes the contradictions they might bring, so unless he found a solution, he preferred to not mess around.
Because of that, he had a small increase in the Mysterious Techniques he used. Even among them, Ranged ones were rare as most Cultivators didn't pick them in early realms like Qi Condensation Realm.
Because in those realms, they neither had enough Qi reserves to waste nor enough Qi Control to actually control their attacks past a certain range.
Once the attacks passed that range, they would simply crumble away and assimilate with the Heaven and Earth.
