Lao Li’s family finally gave birth to a girl! It’s a pity that we are on the road to escape…

Mrs. Li: What should I do? My baby has lumps and no milk to drink!

Jiayin spat out bubbles of saliva and waved her little hands: “Don’t be afraid, I have space, bring your own rations!” then…

Li Laosi: Mom, I picked up a dairy goat on the roadside!

Li Laosi’s wife: Mom, this rabbit hit the tree by itself!

Li Laosan: Mom, I went to fetch water, and the big fish jumped into the bucket!

Li Laosan’s wife: Mom, a handful of rice actually makes a pot of rice!

Mrs. Li’s head was buzzing. With the blessing of her ancestors, she was giving birth to a little lucky girl, who would prosper her family once she was born! As a result, when I turned around, there was a pile of dates, apples and pears on the kang…

Six months ago, tens of thousands of black phantom towers appeared all over the world, floating above the cities. Chemists, physicists, religious people… all of them could do nothing.

Six months later, people became used to the towers and no longer paid them attention.

2. 6 o’clock to 18 o’clock is the game time.

3. All players, please strive to attack the tower.
