After Lin Fan returned to the sect, he had been in retreat, and after three months, all the pills were exhausted, Lin Fan went to the Treasure Tower, sold Xiao Fei's Yan Yu Knife for 1,200 spirit stones, and replaced them all with pills, and after continuing to retreat for five months, the pills were gone, and Lin Fan's cultivation reached the middle stage of Qi refining, and he could break through the late stage of Qi refining at any time.

Lin Fan planned to go to the Contribution Pavilion to see what tasks were suitable for him, Lin Fan first went to receive the fifty lower grade spirit stones issued by his sect this year, and when he went to the Contribution Pavilion and found that there were a little more people today, Lin Fan went to the task bar and looked through it, now that his cultivation is high, there are more tasks that can be done, and Lin Fan looks down one by one.

A task to check the ore vein appeared in front of him, and there was a problem with the dark iron mine in a city under the jurisdiction of the Burning Heaven Gate, check the reason, and reward three thousand contribution points for half a month.

Lin Fan took this task and set off to the city, it took about a day for Lin Fan to arrive at this city, this city is called Tianyun City, Lin Fan found the city lord to explain his intentions, the city lord took Lin Fan to the place where the iron mine was and left, the Burning Heaven Gate has regulations for ore veins and the like, except for the disciples of the Burning Heaven Gate, no one else is allowed to send a hand.

Lin Fan found the steward of the ore vein, and sent the token to explain the intention, the steward was a middle-aged man in the early stage of gas refining, named Wu Qi, Wu Qi: I don't know what happened recently, the miners inside are missing one by one, and I don't know what happened, and no one dares to go down to mine now.

The miners all have the cultivation of the seventh and eighth stages of bone forging, Lin Fan: I'll go down and take a look first. Lin Fan went down to the mine and saw that it was extending in all directions, there were four roads in front of Lin Fan, Lin Fan chose one and walked in on the rightmost one, Lin Fan felt that the more he went inside, the more gloomy it became.

Ding Yilong is a miner in the jurisdiction of the Xuantie Vein in the Burning Heaven Gate, with the cultivation of the eighth stage of forging bones, and he hands it over to the Burning Heaven Gate every day by mining in the ore vein, and the Burning Heaven Gate distributes spirit stones according to the amount of ore.

This day until noon, Ding Yilong has not dug up the spirit stone, Ding Yilong plans to go inside, Ding Yilong does not know how far to go, the mine is not easy to identify in all directions, Ding Yilong suddenly saw a person sitting there, Ding Yilong cautiously walked towards the person, found that it was a dead man, and did not know how long he had been dead, only a skeleton was left to sit there, just now far away thought it was a person, Ding Yilong wiped the sweat on his head and kicked this and that skeleton: scared you Grandpa Ding to death.

The skeleton rolled a long way with Ding Yilong's kick, and suddenly Ding Yilong saw that there was actually a book under the skeleton, Ding Yilong picked it up and looked at it, it said Blood Demon Dafa, Blood Demon Dafa Cultivation Demon Realm Blood Demon Sect Cheats, Ding Yilong saw that it was something in the Demon Cultivation World and wanted to throw him away, and his curiosity allowed him to continue to read it.

Blood Demon Dafa can absorb other people's essence blood to increase his own cultivation, Ding Yilong stopped breathing when he saw this, Ding Yilong found that Blood Demon Dafa does not need qualifications to cultivate, Ding Yilong can't help but feel a little hot in his heart, his own qualifications are limited, otherwise he has not reached the Qi refining period until he is in his thirties, Ding Yilong decided to try it.

At the beginning, Ding Yilong found a miner in the seventh phase of bone forging to start, and easily took him down with his cultivation in the eighth phase of bone forging and took him to the depths of the mine, Ding Yilong began to transport the blood demon Dafa to the man, only to see that the person's body quickly lost weight, the breath on Ding Yilong's body became stronger and stronger, and he felt that he could break through to the ninth stage of bone forging at any time, the miner of the seventh stage of bone forging was gone, only a layer of skin was left between the skeleton, Ding Yilong tasted the feeling of cultivation improvement, Ding Yilong became unwilling to give up this exercise, Ding Yilong only dared to catch a miner a week at first, and then the improvement of cultivation, the courage became more and more bold to catch one person in three days。

At the beginning of the miner's disappearance, Wu Qi didn't take it seriously, this dark iron vein has been dug for three years, and the mine can no longer be dug outside, the miners have to go to the mine to dig it, the mine extends in all directions, often the miners dig a mine back and forth for three days, at the beginning the miner's disappearance steward didn't care, after a long time, there are fewer and fewer people, and the steward feels that something is wrong and sends the news to the Burning Sky Gate.
