I have a Lenovo U41-70.

CPU: i5-5500U 2.4GHz (2 cores, 4 threads).
RAM: 2x4GB DDR3.
GPU: GT 920M 2GB.

Since I don't have enough money yet to build a PC and it will take me another year of saving money, I really want to use an EGPU instead. But how bad the bottleneck will be and will it worth buying a Zotac GTX 1060 6GB Mini to pair with my laptop? If they can perform quite well then should I buy an external monitor?

Um, without Thunderbolt or even ExpressCard, how were you going to hook up the eGPU, via USB?

I've seen miniPCIe to eGPU adapters but you'd have to remove the WLAN/BT combo card and it's only x1.

I can change to cable or use my friend's usb wifi adapter. And yes, I have to remove the card to free the mini port.

To be more exact, I want to play PlayerUnknown's Battleground smoothly at low or medium since I was gifted the game. I know a PC is better in the long run but will this be possible ?

PCIe 2.0 x1 is equivalent to PCIe 1.1 x2. While I don't see any PCIe scaling test for the 1060 it is roughly equivalent to a 980:
None of those are Unreal Engine 4 games but you can see the trend. If it continues to PCIe 1.1 x2 you should see around 63% of the performance it would have at the PCIe 3.0 x16 it was designed for. That would still be twice as fast as the minimum recommended GTX 660.
