What does this mod do? 

• Base damage of the Unique Zhu-Rong Chinese Pistol is increased from 4 to 20. 
• The pistol is added to the Pyromaniac perk weapon list. 
• VATS damage bug is fixed. 
• You can now repair the Zhu-Rong pistol with not only chinese pistols but also .32 caliber pistols. 
• The pistol now deteriorates slower than the vanilla pistol (note: The pistol health pool (weapon durability) is doubled)
• Indeed, Zhu-Rong is no more a useless unique weapon. It is now your best friend. I hope so! :)

Requirements: 

• It only requires Fallout3.esm. 

Compatibility: 

• It may not work well with other mods that changes the "Pyromaniac perk weapons list" or "the weapon stats of the unique Zhu-Rong chinese pistol." 

Installation: 

• Download it, unzip it, and drag and drop the "Data" folder to the "Data" folder in Fallout 3 main installation directory. Then, activate the plugin named "Zhu-Rong my best friend.esp" with a mod manager. 

Note: 

• This work has been inspired by the following works of others: 
     1. Anchorage Gauss Rifle VATS Damage Fix by coelomate 
     2. Modified Zhu-Rong v418 Chinese Pistol by sumpwa 
     3. Zhu-Rong Damage Fix by Sandman1 
• sumpwa's mod increases the base damage of the pistol from 4 to 28 and he also added it to the pyromaniac perk weapon list. However, he didn't fixed VATS damage bug and the base damage seems to be a little bit high. Considering Zhu-Rong's firing speed, I felt it's kinda a magnum with a little bit of high firing rate. 
• Sandman1's mod seems to fix VATS damgage bug but its base damage is the same as that of the vanilla pistol, which makes the unique pistol still useless, and he didn't add it to the pyromaniac perk weapon list. 
• So I decided to make my own to suit my taste with more features.
