After a few hours of hard work, I found the answer.

It's the matchai/spacefish plugin which add new line to my prompt.

Here is the function

# Defined in /Users/liwei/.config/fish/functions/fish_prompt.fish @ line 1
function fish_prompt

  set -g sf_exit_code $status
    set -g SPACEFISH_VERSION 2.6.0

  # ------------------------------------------------------------------------------
    # Configuration
    # ------------------------------------------------------------------------------

  __sf_util_set_default SPACEFISH_PROMPT_ADD_NEWLINE true
    __sf_util_set_default SPACEFISH_PROMPT_FIRST_PREFIX_SHOW false
    __sf_util_set_default SPACEFISH_PROMPT_PREFIXES_SHOW true
    __sf_util_set_default SPACEFISH_PROMPT_SUFFIXES_SHOW true
    __sf_util_set_default SPACEFISH_PROMPT_DEFAULT_PREFIX "via "
    __sf_util_set_default SPACEFISH_PROMPT_DEFAULT_SUFFIX " "
    __sf_util_set_default SPACEFISH_PROMPT_ORDER time user dir host git package node ruby golang php rust haskell julia elixir docker aws venv conda pyenv dotnet kubecontext exec_time line_sep battery vi_mode jobs exit_code char

  # ------------------------------------------------------------------------------
    # Sections
    # ------------------------------------------------------------------------------

  # Keep track of whether the prompt has already been opened
    set -g sf_prompt_opened $SPACEFISH_PROMPT_FIRST_PREFIX_SHOW

  if test "$SPACEFISH_PROMPT_ADD_NEWLINE" = "true"
        echo
    end

  for i in $SPACEFISH_PROMPT_ORDER
        eval __sf_section_$i
    end
    set_color normal
end

Just set SPACEFISH_PROMPT_ADD_NEWLINE to false,

add this line to your config.fish and solve the problem.

set SPACEFISH_PROMPT_ADD_NEWLINE false

Thanks to all.
