「申し」の終止形は「申す」のようです、この「申し」は連用形だと思います。

質問は、動詞の連用形の後に「しく」を付けて、何の意味か表現を表しているのですか？

文語の文法「動詞連用形+しく」について
### Summary

This particular しく is not the 連用形【れんようけい】 of adjective ending し (modern しい).
Instead, this is past recollective auxiliary き in the 連体形【れんたいけい】 + the
ク語法【ごほう】, a.k.a. " _-ku_ nominalization" pattern similar to uses of modern こと,
seen in Old Japanese and persisting in certain set expressions even into
modern usage, such as 曰【いわ】く ("history; reasons, background", literally
something like "that which is said [about something]") or 恐【おそ】らく (originally
"that which is frightening", used in modern Japanese to mean "probably";
compare English "I'm afraid it's the case that...").

⇒ So 申【もう】ししく is ultimately equivalent to modern 申【もう】したこと.

### Grammar

Let's look more closely at your problem word, 申【もう】ししく. This breaks down as
follows:

  * 申し  
This is the 連用形【れんようけい】 ("continuative or stem form") of verb 申【もう】す, the
humble form of 言【い】う ("to say").

  * し  
This is the 連体形【れんたいけい】 ("attributive form") of past-recollective auxiliary き.
This attaches to the 連用形【れんようけい】 of the preceding verb or auxiliary.

  * く  
This is the so-called ク語法【ごほう】 suffix. Historical linguistic research
indicates that this derived from an earlier formal noun あく referring to 「所、事」,
and possibly related to the locative suffix ～こ in words like ここ, or ～か in
words like 住処【すみか】. This attaches to the 連体形【れんたいけい】 of the preceding verb or
auxiliary, but the resulting `[VOWEL]+[VOWEL]` diphthong was not allowed in
Old Japanese phonology, so either one vowel eclipses the other, or the two
fuse.  
For instance, the 連体形【れんたいけい】 of Old and Classical Japanese 言【い】ふ is 言【い】ふ.
This plus あく results in いふあく, and the vowel fusion of //u// + //a// resulted
in the //a// winning out, producing いはく, sound shifting to modern いわく.  
Phonologically, we would expect し + あく to fuse into せく, but one theory is that
the //i// here may have been //i2//, which resisted fusion and resulted in しく
instead. Alternatively, this may be a case where the locative suffix ～く
attached directly, rather than あく.
