Grandma's succulent grew to 2 stories tall, and a businessman offered 300,000 yuan to buy it

Grandma is 70 years old this year. Since she was young, she has loved growing all kinds of flowers and plants. Grandma feels that life only has flavor when you raise plenty of flowers and plants!
30 years ago, Grandma bought a potted succulent at the market and brought it home. Grandma usually did not give the succulent any fertilizer or anything like that, and relied entirely on rainwater to nourish this succulent, yet this succulent grew especially well!
After just a few years, this succulent burst the pot apart. Grandma did not repot it, and just let this succulent take root in the ground and grow however it wanted. Now 30 years have passed, and this succulent has grown to 2 stories tall. Grandma could hardly believe it!
Not long ago, a businessman came to the countryside, saw Grandma's succulent, and said outright that he would pay 300,000 yuan to buy it, but Grandma could not bear to part with it and did not sell. The businessman said this succulent is a mountain-shaped cactus (Shanyingquan), similar to a cactus, with extremely tenacious vitality. The mountain-shaped cactus looks like a mountain yet is not a mountain, looks like stone yet is not stone, but is a living, lush, layered, evergreen succulent plant. Because its shape is towering and abrupt, resembling mountain ranges, it is named the immortal mountain (Xianrenshan).
If you like succulents, you can also grow one at home. Maybe you can grow it this tall too!
