The main mission 2 of exploring the secret realm has been completed. Now the only things missing are some ogre candles from the main mission 1 and a piece of any ore with a purity of 15 or above from the main mission 3. Then this level 0 secret realm can be cleared.

"I have completed a hidden mission, a side mission, and also obtained the core of the secret realm. After clearing it, I may not need to use the energy crystal core and can directly be promoted to a first-level apostle!" Xu Feng said in his heart.

After clearing a secret realm of the same level, one will gain 5% to 10% of the Apostle Experience. Xu Feng's clearance rating this time is at least A, so he can gain 10% of the Apostle Experience. In addition, after completing a hidden mission and a side mission, he is estimated to gain another 10% of the Apostle Experience. Finally, he will obtain the secret realm core, which should allow him to gain more than 15% of the Apostle Experience.

Xu Feng is now at level 70% of zero, and only needs 30% of the apostle experience to be promoted to level one apostle. This upgrade speed is terrifying.

"Okay, the three of you stay on the second floor and continue your previous work!" Xu Feng sorted out his backpack and said to the three people, "I'll go to the first floor. I'll be near the passage. If I see you on the first floor, you know the consequences."

As he spoke, Xu Feng made a threatening gesture towards the three people, took the body of the ogre supervisor with him, and walked towards the sloped passage alone.

Zhao Xin and the other two looked at each other. At this moment, they didn't dare to disobey Xu Feng. They could only stay on the second floor of the mine, waiting for the time to be up and be kicked out of the secret realm.

In the sloped passage, Xu Feng threw the corpse of the ogre supervisor into the secret realm he carried with him. The Yinhuai tree spirit can absorb the flesh and blood of living things to grow and shorten the growth cycle of the Yinhuai spiritual fruit. It can absorb any corpse that has not been dead for too long.

The attribute data showed that human flesh and blood was best used, but the Gnoll Overseer was a humanoid creature after all. Except for its head, its limbs were no different from those of humans. Xu Feng tried to throw its body in. If it didn't work, he could just throw it out.

Unexpectedly, the Yinhuai tree spirit seemed to be interested in the body of the dog-headed overseer as well. After throwing it in, it immediately wrapped the body with its tree roots and slowly dragged it underground.

The Yin Huai Ling Fruit, which originally took 11 months and 23 days to mature, was shortened to one month and ten days. It seems that the BOSS corpse is indeed much stronger than that of an ordinary human corpse.

Seeing the effect, Xu Feng's eyes suddenly lit up. Since the corpses of the kobold overseers were effective, then the corpses of ordinary kobold miners must also be effective. Even if the time shortened is smaller, the accumulation of small amounts will not necessarily be much worse than the corpses of the kobold overseers.

It’s a pity that the bodies of the ogre overseers on the second floor have been refreshed, so we can only wait until the next refresh.

Xu Feng walked through the sloped passage and came to the first floor of the mine. He found a position close to the passage, took out a pickaxe, and began to chisel hard at the rock wall.

The other places on the first floor of the mine were very crowded, except for the entrance where there were not many people.

"Hey, brother, don't get too close to the entrance of the passage. After the second floor is refreshed, those ogre miners may rush up. If you get too close to the passage, you will be besieged by them!" A middle-aged man wearing an old man's shirt, with a strong build and shiny skin, shouted kindly to Xu Feng.

"It's okay, I don't like crowded places." Xu Feng smiled and waved his hand.

"Okay, Lao Niu, he just became an apostle and is in great spirits. He doesn't listen to other people's opinions. So don't waste your breath." The person at the side consoled him with a smile.

Niu Zhigang shook his head, sighed secretly, and ignored Xu Feng, and just kept chiseling at the rock wall.

In that situation, let alone a level 0 apostle, even a level 1 apostle would suffer a great loss if he was caught off guard and surrounded by dozens of kobold miners.

At the beginning, it was not that no one wanted to mine near the entrance of the tunnel, but after several people died, no one would go to mine within five meters of the entrance of the tunnel.

Five meters is a safe distance. Even if a kobold miner suddenly appears, there is still time to react, and then you can decide whether to fight or flee based on the situation.

Xu Feng dug for a while, and soon a piece of ore the size of a human head rolled down from the excavated rock wall. When he picked it up, he found that it was a piece of iron ore with a purity of 12.

There are people from the Black Tiger Gang buying ore at the entrance of the secret realm. The price varies according to the purity. An iron ore with a purity of 12 can only be sold for about three to five hundred yuan. If you carry it to the city yourself and sell it to an apostle of the secret realm who has a side job of forging, the price can be higher.

However, the Level 0 Secret Realm Apostles do not have space packages, so the ores they dig out, even if they are of good purity, are not easy to carry. Most of them are sold to the Black Tiger Gang at the entrance of the secret realm.

Unless they dig up more precious ores, such as secret ore, they will choose to take them back to the city to sell them.

"The purity is only twelve, which does not meet the task requirements!" Xu Feng shook his head, threw the iron ore at his feet, and continued to chisel towards the rock wall.

Two hours later, there were more than a dozen pieces of ore piled at Xu Feng's feet, most of which were iron ore and copper ore with purity levels of three to five. After digging for so long, the one with the highest purity was actually the first piece of iron ore with a purity of twelve. This made Xu Feng couldn't help but sigh.

"Without the skills of mining and prospecting, if you want to be a miner, you can only be a blue-collar miner who works the hardest but earns the least!" Xu Feng sighed and thought to himself.

There is no wrong version in the 1619 book forum!

Skill scrolls for prospecting and mining are still very valuable in the early stages, and the price will slowly drop in the middle and late stages. As for wanting to comprehend them by yourself, unless you are an old miner who has worked for decades, it is simply wishful thinking for an ordinary apostle to comprehend mining skills by digging for a few days.

At this moment, the light in the mine suddenly dimmed. The experienced apostle immediately stopped mining and drew out the weapons he carried with him.

Xu Feng's Taoist soldiers had long since turned into a pile of ashes because their time was up, and now only Xu Feng was left.

Seeing the actions of other miners, Xu Feng also knew that the Gnoll miners were about to be refreshed, so he stopped mining, took out a stack of paper talismans, and held them tightly in his left hand.

The next moment, a wolf-like howl sounded, and a dozen kobold miners were refreshed. However, for the first floor of the mine that was like a maze, these dozen kobold miners were almost evenly distributed on one floor, and there were only two or three kobold miners in each area at most.

For the hundreds of secret realm apostles on the first floor, these dozen or so kobold miners were just entertainment in their boring work. Before the wolf-like roars ended, they immediately turned into shrill screams. If dog lovers heard them, they would definitely feel pity and even shed tears.
