"This is the Ghost Prison Gate, not to mention you, even the Jindan period monks must be greatly affected under this gate, otherwise how can we detain those Jindan period monks who have cultivated to the heavens, just now you and I have walked all the way through such a long passage, don't look at the way seems to be extremely safe, it is because the Heavenly Order on our body already has the authority of the Sin Palace. Otherwise, there are countless prohibitions in it, and the Jindan period monks will not be able to break through this hell passage at all. ”

Tiangong Island is really dangerous. Ishihara smiled bitterly, and decided in his heart to honestly work hard for a while first, Sun Gong didn't say much when he saw this, took out the heavenly order and inserted it into a groove on the ghost door, and then made a series of complicated handprints, and the strange syllables in his mouth kept spitting out, urging the giant gate to get brighter and brighter, and a very weird-looking black gas shrouded the entire giant gate.

However, the giant door did not open, as Sun Gong's magic trick was completed, these black gases suddenly formed a huge whirlpool, emitting a powerful suction force enveloping Ishihara's body, and Sun Gong's voice came from his ears, "Don't resist", and then he was directly swallowed by the ghost gate along the suction and disappeared into the passage.

Whew, whew! The rolling heat wave came to his face, which was hundreds of degrees high, although it could not hurt Ishihara, but it also made his face suddenly turn red, and then Ishihara opened his eyes, and his vision was red, as if he had come to a sea of fire, and they were standing in a central square, looking back, they couldn't see the existence of the ghost gate at all.

"Welcome to the Temple of Sin, this is the first level of the Temple of Sin, the Flame Layer. Sun Gong's laughing voice came from the side, and the robe on his body automatically changed into a clean and neat blue power suit, which can automatically adjust the temperature and adapt to the environment here.

Fortunately, Ishihara also received such a set of special clothes for Tiangong Island in advance, and his heart moved, and the clothes on his body automatically changed to the corresponding style, and he immediately felt the temperature drop, he had already learned about the introduction of the Temple of Sin from Sun Gong's mouth before.

The Temple of Sin is located at the bottom of the volcano under Tiangong Island, and it is rumored that this volcanic vein, leading directly to the depths of the underground lava, is one of the deepest places in this world, divided into eighteen layers, the first six layers are the spiritual flame layer, which is the six most essential layers of the Temple of Sin.

However, most of the earth fire was supplied to Tiangong Island for Tiangong Island to operate, and the remaining part was concentrated and transformed into better quality soul fire, and it took on a lot of smelting and sorting work, and it can be said that the hardest and most tiring work with no technical content was carried out here.

The middle nine layers are the spiritual vein layer, there are nine medium-sized spiritual veins gathered here, for immortal cultivators, spiritual veins are indispensable, so these nine medium-sized spiritual veins are very important, supplying the cultivation of hundreds of thousands of monks on the entire Tiangong Island, and according to the technology of Tiangong Island, a large number of spiritual plantations, spiritual animal gardens, spiritual ore veins and other places have been opened up, and the utilization technology of spiritual veins far exceeds the rest of the places, so it can be said that there is almost no trace of excess spiritual energy leaking out.

And the last third is the lava layer, which goes deep into the underground lava, which flows a large number of precious metal raw materials, and there are many treasured spiritual fires, heavenly materials and earth treasures, etc., which need a large number of monks to mine in it. Not to mention the harsh and dangerous environment here, there are also a large number of lava beasts, which are extremely dangerous, and they are the places with the greatest casualties in the Temple of Sin.

Sun Gong led Ishihara out of the central square, and before he went far, he saw a scene in full swing, with black pipes ten zhang thick all over this underground space, standing up to the sky, running through the entire eighteen-story sin hall, and going straight into the underground lava, extracting countless underground lava flames.

Next to these vertical pipes, dozens of parallel pipes branched out from holes and flowed in all directions, passing through a series of workshops of strange styles, in which a large number of monks were performing a specific technique, each of which used a specific method to extract a specific raw material from the lava, which was then roughed and solidified by others to form pieces of metal and transported to other places.

Therefore, a lava comes out, most of the materials that can be used will be extracted, and in the end, only the rock lava that has almost no use is reintroduced into the ground, but it is a pity that although Tiangong Island is highly skilled, there is probably only one layer of a lava that can be used, and most of the lava is still pumped back into the ground after being extracted from heat.

"The Spirit Flame Layer is the place where the raw materials of the Temple of Sin are processed, in addition to the collection of external resources on Tiangong Island, most of the other island's specialties can be said to be obtained from here, although many of these raw materials are of little use to monks from the outside world, but in the hands of Tiangong Island, they can turn decay into magic and refine them into powerful weapons. ”

Sun Gong led Ishihara to visit, first walked to a workshop, and saw the fiery red hot lava through a ten-meter-diameter semicircular passage through the center of the workshop, next to a hundred monks, most of whom were Qi cultivation period monks, divided into three rounds, they enveloped hundreds of meters of pipes through the prohibition and jointly cast the spell, and then under the guidance of a foundation building period monk, a specific mineral in the lava was refined.

Soon, little by little red metal liquid rose into the air, and after converging to a certain extent, three other monks next to it quickly cooled and shaped it, forming a cubic meter of metal and transporting it to the warehouse next to it for accumulation, and when it was fully stored, it would activate the teleportation circle in it and directly teleport to the surface, which was extremely fast.

Ishihara looked at this familiar picture, and the monk directly replaced the heavy machine, exerting the creative power to make Ishihara feel the urge to talk to them. It was only when they came here that the monks only looked at the two of them, bowed their heads and hurriedly went on with their work.

Although it seemed that these monks were in full swing, they gave people a sense of lifelessness, no one was talking or chatting, just silently completing their work, and the two idlers who were visiting everywhere looked very discordant.

Sensing Ishihara's curiosity, Sun Gong said softly: "The monks here are relatively less responsible monks, and most of them have only been punished to work here by inadvertently or violating some daily regulations. It's just that the work here is extremely heavy, and a monk has to work tirelessly every day to complete most of his own tasks, so he doesn't have time for small talk. But fortunately, this is also the safest place in the Temple of Sin, and everyone is just thinking about completing their mission as soon as possible and leaving here as soon as possible after the sentence. ”
