Zhou Feng could quickly increase his cultivation with the first two methods.
In fact, there was another more direct method, but there were too many uncertainties.
That was to obtain more passive skills.
If Zhou Feng could obtain more passive skills, his strength would increase.
However, quickly obtaining passive skills was a problem that was worth studying.
At present, he had discovered that the skill panel's progress bar would speed up if he absorbed a large amount of Spiritual Qi. Other than that, the progress bar would only speed up through the Demon-Devouring Gu and Soul Harvesting.
Thinking about it, if he wanted to speed up the progress bar, he would basically need to obtain additional energy?
Zhou Feng made a simple guess.
Extracting a passive skill required energy, and the skill panel could only obtain energy through Zhou Feng.
Therefore, every time he absorbed a large amount of Spiritual Qi, the progress bar's progress would increase.
'If that's really the case, isn't the Demon-Devouring Technique the perfect fit?'
Zhou Feng found that the Demon-Devouring Technique was very suitable for him.
The Demon-Devouring Technique could completely devour everything in the target, including the opponent's Spiritual Qi.
As long as Zhou Feng devoured a person, he could speed up the progress bar. It seemed that he had to master the Demon-Devouring Technique.
He also had to master the Demon-Devouring Battle Art and the Demon-Devouring Armor.
'Oh right! I can also start to try raising Gu!'
The more Zhou Feng pondered, the more he felt troubled.
Why was this path of cultivation so troublesome? Couldn't it be a little more simple and crude?
'Wait!? There's someone?'
Suddenly, Zhou Feng felt a trace of danger.
This feeling was as if someone was spying on him.
What was going on? Someone had dared to make a move in the Medicine Tower!?
One had to know that this was the center of the Medicine Tower. Once there was any movement, it would be easy to attract a large group of people.
There were quite a few old Soul Altar cultivators guarding the Medicine Tower.
Even an Elder had been stationed there, but he seemed to have left the Medicine Tower in order to deal with the Voodoo Cult.
"Heaven-Sealing Formation!"
Without waiting for Zhou Feng's reaction, a black figure instantly slipped into his room.
Then, a formation was activated, enveloping the entire room.
Wasn't this familiar formation the Heaven-Sealing Formation Han Qi had used during their battle?
At that moment, Zhou Feng's room was sealed by the Heaven-Sealing Formation. No sound or movement could be heard from inside.
"Die!"
Han Ming, who was completely wrapped in black, didn't say much using the formation. He immediately chose to attack.
That's right! The black-clothed man who had just sneaked in was Han Ming.
Han Ming had actually sneaked into the Medicine Tower and found Zhou Feng's room accurately.
After the sky turned dark, he took advantage of the fact that everyone had returned to their rooms.
Han Ming found an opportunity and rushed into Zhou Feng's room. He used the Heaven-Sealing Formation and sealed the room's interior into a space.
'As long as I get the Purple Jade Bell, I can immediately retreat!'
In Han Ming's mind, ambushing Zhou Feng and taking back the Purple Jade Bell shouldn't take too much time. He would still have enough time to escape from the Tri-Gu Sect.
Therefore, swiftly killing Zhou Feng was the most important part of this operation. He had to kill Zhou Feng instantly so that he wouldn't attract attention.
For this, Han Ming had prepared three Essence-Breaking Needles!
Essence-Breaking Needles! Each of these was a soul artifact that could penetrate any Spiritual Qi defense.
The Essence-Breaking Needles were powerful disposable soul artifacts.
They were usually kept on the Soul Altar. The Essence-Breaking Needles had to be used as a killing move because they would be useless after one use.
Three tiny silver needles whizzed over.
"Purple Jade Bell!" Zhou Feng subconsciously summoned the Purple Jade Bell.
To be honest, he didn't quite react.
His days in the Medicine Tower had been too peaceful, causing his vigilance to drop quite a bit. In addition, he was confident in his perception, so he would detect anyone that got close to him.
All these reasons caused him to fall into a trap of his own making.
Zhou Feng never expected someone to be so decisive and suddenly sneak into the Medicine Tower to attack him. They even managed to hide from his super-strong perception.
Han Ming hid from Zhou Feng's perception because he used a concealment talisman.
It could be said that in order to end the battle quickly, Han Ming had made ample preparations.
The Purple Jade Bell slowly appeared, and a purple curtain of light enveloped Zhou Feng.
Unexpectedly, the three Essence-Breaking Needles broke through the Purple Jade Bell's curtain of light.
'As expected! This kid really refined the Purple Jade Bell!'
Han Ming looked at the Purple Jade Bell, and his breathing instantly became heavier.
As long as he obtained the Purple Jade Bell, he would be able to fly far away!
Although he had wasted three Essence-Breaking Needles, which made Han Ming's heart ache a little, it was all worth it.
Not only did the Essence-Breaking Needles break through the Purple Jade Bell's light curtain, but they even broke through Zhou Feng's Demon-Devouring Armor outside his body.
It was not a joke to specifically counter Spiritual Qi protection.
'That was close!'
Zhou Feng felt a sharp pain in his chest, but the three Essence-Breaking Needles were blocked.
This was because of the passive Bone Coating.
The three Essence-Breaking Needles didn't harm Zhou Feng due to Bone Coating's damage reduction and his terrifying physical body.
"How is this possible? They didn't kill him!?"
Han Ming, who was originally full of confidence, couldn't hold himself back when he saw this. His eyes were filled with disbelief.
Impossible! It was impossible for someone to rely on their physical body to withstand these Essence-Breaking Needles.
Moreover, this person in front of him had just broken through to the Soul Altar realm!
"Die!"
After stopping the Essence-Breaking Needles, Zhou Feng's expression instantly darkened while pitch-black Demonic Qi slowly surged out of his body.
Compared to before, Zhou Feng's current battle prowess was more fearsome.
After breaking through to the Soul Altar realm, he had been unable to consolidate his strength due to the various hidden injuries in his body.
Even so, he had still killed Han Qi head-on.
Although he had used underhanded methods, Zhou Feng's battle prowess was formidable.
After catching and consuming the spirit fish, more than half of the hidden injuries in his body had been eliminated. Thus, he could now harness more power turning it into raw explosive physical strength!
Zhou Feng threw a seemingly plain punch, which was imbued with Demonic Qi.
"You!"
An armor instantly rose up from Han Ming's body. This was an ordinary soul artifact. Although its defensive power couldn't compare to the Purple Jade Bell, it was still pretty good.
However, a huge force penetrated Han Ming's entire body.
Armor Piercing Spear! Aura Blade!
Two passive skills were triggered instantly.
A mouthful of blood spurted out of Han Ming's mouth.
