Early the next morning, Huo Hai and Shi Zu took Du Wu and a group of other young heroes to the entrance of the Fire Dragon Trapped Immortal Array. This entrance is on the side of the island, diagonally deep into the ground. You can also enter the battle from the crater in the center of the island, but the terrain there is more dangerous, and it is straight up and down, not as good as here, the slope is gentle, and you can walk slowly.

The entrance is a black hole, and the rocks on both sides of the cave are pitch black, which seems to be the result of being burned by the earth's core fire for many years. When he arrived at the entrance of the cave, Shi Zu instructed Du Wu a few more words, meaning that there was no need to be reluctant, if he couldn't stand the suppression of the large array inside or the heat of the earth's core fire, he would withdraw in time and so on.

Du Wu nodded to show that he understood, because the agreed agreement was only for Du Wu to break the formation alone, and no one else was allowed to help, so Du Wu said goodbye to everyone, took out the holy water spirit bead, held it in his hand, and walked towards the cave.

Du Wu walked into the cave, raised the Holy Water Spirit Bead, and looked around with the help of the blue light emitted from the Holy Water Spirit Bead.

I saw that this place is somewhat similar to the Flaming Mountain in the western Xinjiang, but it is also a little different. The rocks of the Flaming Mountains are all red, but the rock walls here are all black, and both are the same heat, and the further down you go, the more you feel the heat. However, Du Wu has the Holy Water Spirit Bead to protect her body, and her own physique has also been cultivated to an extremely high level, so this heat is nothing to her.

The path here is oblique downward, and the stones under your feet and the cave walls on both sides seem to have been formed by the cooling of magma after the eruption, but the general crater is straight up, and I don't know why there is an oblique cave here in addition to an upward crater, and even the sea of fire does not know the cause of this cave.

Du Wu went all the way down, there were no plants and animals in the dark cave, Du Wu felt very monotonous and boring, thinking that if it wasn't for breaking the formation and fighting for the master, he would definitely not come here again.

After walking down for about a thousand feet, the terrain gradually flattened, and the direction of the cave changed from oblique downward to spiral, and it seemed to slowly rotate downward around the center of a circle. Du Wu felt bursts of scorching waves of air rushing upward, mixed with a choking smell of sulfur. Du Wu silently carried the nine turns, and the true qi swam through the body, expelling the uncomfortable feeling from the body, and continued to walk down.

After walking down about a few hundred feet around the spiral-shaped cave, the cave suddenly disappeared, and a red light appeared in front of him, which turned out to be a hall.

Du Wu found himself on a stone platform on the side of the hall, which was circular and could be surrounded by miles or so. Du Wu looked at his feet and found that there was a pool of magma more than ten zhang deep, the magma was tumbling and bubbling, and from time to time sparks jumped out of the magma pool.

In the center of the magma pool, there is a huge stone ball, suspended in the air. The stone ball was roasted red by the heat of the lava and spun there. Around the stone ball, there are nine fire dragons flying and coiling. Nine fiery dragons are delicate, and dragon beards and dragon scales are lifelike. It's like a real dragon.

The fire dragon took on a fiery red color, and against the background of the surrounding dark stone walls, it looked like it was about to break through the air and fly away. However, there seemed to be another invisible barrier around them, and these nine fire dragons just couldn't break through, so they could only fly around the stone ball.

Du Wu knew that this was the Fire Dragon Trapped Immortal Array, and he heard the master and the sea of fire talk about it, this big array was to suppress the geocentric fire in the underground magma. The second is to absorb part of the firepower of the Xuanhuo in the center of the earth with the help of stone balls and nine fire dragons, and release it from the large array, which will play a certain suppressive role for the martial arts practitioners on the entire Huoyun Island.

Du Wu knew that in order to break this great array, he could only break the suppressive effect of the large array, but not the suppression of the great array on the earth's core Xuanhuo, otherwise the volcano might erupt in advance and bring boundless catastrophe.
