How can i make these npcs turn slower?

C = game.Workspace:GetChildren()
	for i = 1,#C do
		if C[i]:FindFirstChild("Humanoid") and C[i].Name ~= character.Name then
			if C[i].Humanoid.Health ~= 0 then
	if C[i]:FindFirstChild("Torso") then
		if (C[i].Torso.Position - character.Chest.Position).Magnitude <=400 then
			character.Humanoid:MoveTo(C[i].Torso.Position)
		end

i have a script set up that detects players when they are nearby. here is the script

how can i make it so the npc turns slower?

I dont really know, i'm kinda new.. But don't you have to do something with the properties?, I think you have to click the humanoid, than click Properties (hotbar ''View'') scroll down in properties and change the speed of the npc.
