What's the story about Tang Sanzang Road blocking the Flame Mountain?

The Journey to the West said in the fifty-ninth report that after the disaster of the fake Monkey King was eliminated, Tang Priest and his disciples continued to travel westward. Soon they felt strangely that it was the season in Sanqiu, but gradually they felt steaming hot. Bajie thought he must have reached the place where the sun went down. Friar Sand suspected that it was because of the bad weather and the summer vacation in autumn. At this time, an old man on the roadside revealed the mystery in one sentence: We call it the Flame Mountain, which is hot in all seasons, without spring or autumn. What is this flaming mountain? According to the old man's description, the mountain has 800 miles of flames and nothing grows around it. Over the mountain, even the copper skull iron body Hwa-Sung Do juice. It is also described in the book that when the Monkey King adjusted the banana fan to put out the fire, the mountain wall was ablaze, the rotor flew to the sky in thousands of feet, and the Great Sage's two hairs were burned off, leaving only a naked red ass. It can be seen that this flaming mountain is really fierce. How did the Flame Mountain come into being? Monkey once suspected that the monster Niu Wang Mo here set the fire. However, the land god here explained that when Monkey Sun was making a scene in the Heavenly Palace, he was caught by mistake and thrown into the gossip furnace by the old gentleman on the throne to refine the five flavors. Unexpectedly, the Monkey King not only didn't burn to death, but also became indestructible. The Monkey King jumped out of the furnace and knocked out some fire bricks used as footstools under the gossip furnace. These bricks fell to the lower bound with flames, forming a flaming mountain. Especially in midsummer, under the scorching sun, the heat waves are rolling, the crimson smoke clouds are transpiration, and the red rocks are shining, which is more like a burning fire. The mountain is majestic and tall, winding and undulating, with bare rocks and no grass on it. The Tang Priest and his disciples want to cross the flaming mountain.
