After reaching close to the mine, Yue used her Phantom World and Li Feng used his Xuanwu's Great Isolation to sneak inside. Then they met up with their mind controlled superior and was relieved to find out that everything was fine. No one had suspected anything and Li Feng also had managed to get all his contribution points even for the days he was absent.
After that, Li Feng and Yue settled down in the mine for the the time being. As they had just reached the foundation establishment realm, both of them took some time to perfect their control over their current realm before starting their cultivation again.
But even after their realms became stable, they did not give their full focus to cultivation. That was because, with their new realm, a lot of new, powerful and intersting techniques had became available to them. So cultivation became a secondary goal for them for the time being and mastering those techniques became the primary focus.
Even though it was their secondary focus, Li Feng and Yue did not completely slack off on their cultivation. They regularly cultivated for some time after they were done with practicing the techniques. In this way, three months passed and only then Li Feng was told that it was time for their group of disciples to go back to the sect.
In these three months, Li Feng had profited a lot. He had managed to master quite a few techniques, had earned a lot of spirit stones and had managed to reach the second level of foundation establishment realm. Overall he was very satisfied with his progress.
Before leaving the mine, Li Feng secretly took care of the disciple who was mind controlled by Yue. He was a evidence that Li Feng wanted to get rid off. As for how he managed to do that, it was very simple.
As that person was already mind controlled, Yue just made him to behave a bit weirdly everyday. He started to become someone who was getting frustrated with his lack of progress in cultivation. Then one day, in his frustration and a bit of bad luck, he ended up making one of the brutal foundation establishment realm elders angry. And that elder ended up killing that mind controlled guy with a single palm strike.
While thinking about how perfect his journey to the mine had been, Li Feng happily waited for the ship to arrive that would take his batch of disciples back to the sect. Soon he saw a dot in the sky that was getting bigger and bigger. That was the ship which was coming to take them back.
But as the ship got closer, Li Feng noticed that something was wrong. No one else had noticed it as the ship was still very far away, but with his powerful spiritual sense, Li Feng noticed that the condition of the ship was quite bad. It was broken in various parts and looked to be in a terrible condition.
As he was wondering why the ship was in such a beatdown condition, he soon noticed the reason. A group of flying demon beasts were chasing behind the ship. Most of the demon beasts were either rank 3 or rank 4 but one large bird at the front with blue feather and lightning crackling all over its body was at the fifth rank. That means it was as strong as a foundation establishment realm cultivator.
Seeing all this, Li Feng immediately understood that trouble was coming. If that bird was the only demon beast attacking the mine, then the several foundation establishment realm elders present there should be able to defend against it without much trouble. But Li Feng had a bad feeling about this whole situation and he always trusted his instincts.
Soon Li Feng found out that his bad feeling was on point. With his powerful and long range spiritual sense, he soon found that a large group of land monsters were also following behind the bird. They were slower than the bird and that was as the reason why they entered Li Feng's sensing range later.
Among the land monsters, there were several rank 5 beasts. Six to be exact. But what worried Li Feng the most was a small mouse like beast which was completely golden in colour. This mouse was giving off the aura of a rank 6 beast. Li Feng was sure that none of the foundation establishment realm cultivators present here would be able to match it in strength.
Li Feng immediately started to thing about a way to take advantage of this situation. With so many beasts suddenly attacking, Li Feng was sure that the defenses of the mine would take a huge amount of damage. The mine had several defensive formations which needed very little power supply with the presence of the spirit vein in this area. So Li Feng was not sure if the beasts would be able to completely destroy the mine or not.
But the people present here would definitely not be able to completely beat the monsters and would need to ask the sect for reinforcements. Only with the sect taking matters at hand, would this trouble be over.
As currently Li Feng was acting as an early stage Qi gathering relam cultivator, his chance of survival should not be very high. But as actually he was a powerhouse who could defeat even a late stage foundation establishment realm cultivator, Li Feng was not really worried about his safety. But he needed to keep his true strength hidden from everyone else.
With this plan in mind, he positioned himself at the back of the gathered disciple so that he could go inside the safety of the mines in a moments notice. As Li Feng started his preparations, the ship finally became visible to other other disciples' too. And soon they noticed the beat down nature of the ship which made them curious but not overly worried as a foundation establishment realm cultivator was on the ship.
Then finally they noticed the large flock of bird monsters and immediately all the blood drained from their faces. Most of the birds were either rank 3 or rank 4, which meant most of the disciples were powerless against them.
Realising this, immediately the disciples present in that place started to run around like headless chickens. Li Feng also took advantage of the Chaos and went inside the mine area. While getting deeper into the mines, he also kept an eye on what was happening with the ship and the monsters in the outside area with his spiritual sense.
Li Feng soon found the large ship to crash land in that area. But fortunately all the passengers inside were alright. Two foundation establishment realm came out of the ship and one of them immediately started attacking the swarm of flying beasts. While he prevented the monsters from getting closer, the other elder and disciples also started to run toward the interior of the mine.
That was how the battle between the demon beasts and humans started in the mine.
