After Fan Guyu's whole body disappeared inside the pool of blood, Li Feng deactivated the technique. Now he could summon Fan Guyu as his servant whenever he wanted. Actually Li Feng really don't have any need for a servant who was only a 4th level Qi gathering realm cultivator, so he was mainly doing it to punish him.
As for the remaining three people, Li Feng decided to kill them too. But before that he interrogated them thoroughly with Yue's Phantom World. These three disciple turned out to me quite capable. They had joined the sect only one and a half year ago and had already managed to reach the 3rd level. The reason behind their quick progression was actually a formation plate.
This formation plate had a mini spirit gathering array drawn on it. By deploying this, they could increase the density of spiritual energy in their cultivation area greatly. It was really a very helpful thing.
Li Feng had studied array formations quite a bit and was confident that he would be able to draw a mini spirit gathering array. But to darw an array, just having the knowledge was not enough. He would also need array flags and equipments, which he lacked for the time being.
That was why getting this formation plate was a big deal to him. Even though this plate could only be upgraded with a regular upgradation card, Li Feng was fine with that. With this, his already high cultivation speed would become even faster. This would also help Yue with her cultivation progress.
After making sure that the three disciples had no more things to hide, Li Feng easily killed them with his point piercing technique. As he had made the blood needle to be extremely thin, they made almost no visible wound on their body. After this he started his plan to hide this murder.
For that reason, he used his blood clones to attract a demon beast to this place. It was a lamprey like fish that lived in soil instead of water. Li Feng's blood clones had entered it's body from the gaps between the scales and had wrecked havoc. So this monster was extremely angry at this moment.
So as soon it noticed the bodies of humans, it started rampaging. The bodies were destroyed in it's rampage and the whole mine started shaking. Soon one of the high grade Qi gathering realm disciple came to check the situation and killed the demon beast. After asking around he got the information that four disciples had came to this area to mine and some pieces of flesh and blood was found in this area. So obviously he regarded all of them to be dead by the hands of this demon beast.
As for Li Feng, he had already moved away from this area before his blood clones guided the beast there. So no one had any reason to suspect him for anything at all. He had also not made any contact with the people who were killed. So he simply came out of the mine, handed 52 spirit stones to the person handling the mined spirit stone count, got his 5 contribution points and went to rest like other disciple.
...
From the next day onward, Li Feng started to diligently visit the mine everyday and came out with about 50 spirit stones. Just enough to get the maximum amount of sect contribution points. He looked like a diligent disciple and was contributing the most in the mine.
But actually, Li Feng was quickly mining for about 500 spirit stones everyday and was keeping them for himself. This did not take much time so for rest of the day, he cultivated diligently. Just like that, in less than two weeks, even with with him trying his best to solidify his cultivation base as much as he could by cultivating slowly, Li Feng managed to reach the peak of the Qi gathering realm with the improved cultivation condition of the spirit mine and the Spirit gathering array.
The mini spirit gathering array became a regular spirit gathering array after being upgraded with a regular card. This array was more than 10 times more potent than the mini version so Li Feng's speed of cultivation skyrocketed. That was why he was able to reach the peak of Qi gathering so quickly.
Now that he was at this realm, Li Feng started to think about his foundation establishment. For most Qi gathering realm cultivator, this was a big hurdle. They needed to prepare rare pills like foundation establishment pill and also needed to prepare a place with high concentration of spiritual energy. They also needed to master their cultivation technique to a certain degree and only then one would be able to try to break through. Even then, the chance of a successful breakthrough was quite low. So they also needed to prepare a lot of healing medicine with keeping the high chance of failure in mind.
But Li Feng had no worries about it. His talent was unparalleled through all eras of the universe and he practiced a supreme grade cultivation technique. So he did not need the assistance of any pills for his foundation establishment. And now that he had the spirit gathering array he would have more than enough spiritual energy when breaking through. So the last worry he had also disappeared just like that.
But Li Feng was not planning to break through to the foundation establishment here in the mine. With his talent and powerful technique, he was sure that at the time of his breakthrough, he would manifest some kind of heavenly phenomenon. So he first needed to find a remote location to make his breakthrough.
So for now, Li Feng wanted to go search for the treasure mentioned in the map. Actually it was not a treasure but a hidden cave abode of a golden core realm cultivator. When he upgraded the map, this information appeared. Now he was looking forward to what he would be able to find there. And if that cave abode was remote enough, he could even try to make his breakthrough there.
But for that, he needed to get away from the mine first. As for how he was going to do that, Li Feng already had a plan. There were five foundation establishment cultivator present in the mine. The mine was quite large so at least five foundation establishment realm cultivator were needed to be present here.
But those high level cultivators did not really bother with the daily tasks and it was mostly high and mid level disciples under them who were responsible for those duties. Most of them were way weaker than Li Feng and Yue.
With Li Feng, Yue had also enjoyed the benefit of the spirit gathering array and Li Feng had also given her a lot of his blood. That way, she had also managed to break through to the third rank. Now she should be able to use her Phantom World to deeply manipulate and control even a high grade Qi gathering realm disciple.
That was what Li Feng was planning. He was going to ask Yue to control the mind of one disciple so that he could cover for Li Feng. Then after coming back, Li Feng would hve reached the foundation establishment realm and by then he should be able to get rid of that disciple even under the eyes of other foundation establishment realm cultivators.
Just like that, Li Feng got ready to depart from the mine in search of the cave abode of a golden core realm cultivator.
