The recovery rate of normal monsters ranged from 3% to 10%, for BOSSes, it ranged from 10% to 15%, and for Tusk Pig s, it was at least 13%. Its HP was at 6000, which meant that the Tusk Pig's recovery rate was 780 points per second.

Dongfang Qingyu carefully calculated the damage he dealt to the Tusk Pig, and it was at around 230 points. With just this bit of attack, it was impossible to harm the Tusk Pig, let alone kill it, it had been so long since he killed a BOSS, Dongfang Qingyu had actually forgotten about this. He had always been measuring the recovery rate of Tusk Pig based on ordinary monsters.

Dongfang Qingyu frowned and thought for a while before he started to adjust his strategy.

"Resurrection Arts!"

"Resurrection Arts!"

"Resurrection Arts!"

"..."

They were all Oak Iron Tree, surrounded by a triangle, and were all around five meters away from the Tusk Pig. They just happened to be at the edge of the Tusk Pig's perception, so it wouldn't be too strong, but it wouldn't be too far away either.

"Chi, chi, chi, chi …"

"Spikes!"

After the first shot, it was the second, then the third, and when it came, the Tusk Pig would hit the first Oak Iron Tree. The second time, it would hit the second, and the third, because the one it attacked was the third.

Although the wooden spike's attack was sharp, it was spread out. The Tusk Pig's thick skin and thick flesh did not hurt too much, so it was unlikely for it to go crazy. This way of dispersing had two benefits. First, he could hold onto the Tusk Pig and prevent himself from losing patience to escape. Second, he could stall for time. Dragging the time had two more benefits. First, this way, the Oak Iron Tree could have a buffer of a few seconds and its HP could recover a bit, allowing it to hit the Tusk Pig one more time. It was based on this method of attack where the Tusk Pig would need to hit the Oak Iron Tree four times in order to make it die.

The second benefit was prepared for Dongfang Qingyu.

"Corruption Art!"

"Bone Fire Art!"

"Corruption Art!"

"Corruption Art!"

"..."

The Voldemort's Hand Bone Wand never stopped releasing its skills while facing the Tusk Pig. Furthermore, it was not like before, where all of its skills were thrown at, only used two skills, 'Corruption Art' and 'Bone Fire Art'. It used less of its' Bone Fire Art ', and where would its 60 second cooldown be?

"Bone Fire Art!"

"Corruption Art!"

"Corruption Art!"

"..."

To the Tusk Pig, this little bit of damage was not enough to attract its attention. However, Dongfang Qingyu's goal was also not to attack.

< The Cosmos > had an interesting setting regarding skill proficiency. One had to face the monsters while practicing in order for one's experience to increase faster. If someone were to say that one was practicing skills in seclusion, then that person would definitely be a fool. The experience for practicing skills against the empty space increased by 1% for practicing against monsters. This was also why, when many players didn't kill a monster to level up, their skill experience points didn't increase at all.

Monsters gave bonus skill growth to players, while Bosses gave even greater bonus skill growth, three times more than normal. This was Dongfang Qingyu's goal. It was a rare opportunity to get a BOSS.

After the Resurrection Arts levelled up, the pressure on Dongfang Qingyu decreased greatly. Resurrection of one more Oak Iron Tree meant at least three more lives.

Seeing the increasing amount of Skill Experience Points, Dongfang Qingyu's heart started beating faster. All this time, the boss had always been a sacred figure to the players, a precious symbol of experience, wealth and status. He had thought the same way, but it was not a deep feeling.

He was happy, but he didn't feel that the Boss was that precious. His thoughts had completely changed tonight.

At 3: 30 in the morning, the sweet voice sounded again.

At four in the morning, when the Oak Iron Tree was used up, Dongfang Qingyu could only use Fire Spirit Turtle as a substitute. Fortunately, Dongfang Qingyu had already lured the Tusk Pig deep into the Wild Pig Forest, and there were tall trees everywhere.

At five in the morning, the sky started to turn slightly cold, and the Corruption Art levelled up once again.

In one night's time, 'Corruption Art' consecutively rose three levels, even if it was just an elementary skill, it was unprecedented. Around 8 AM, the 'Poison Fang Art' that he used less often also levelled up.

There were only a few Fire Spirit Turtle left, Dongfang Qingyu did not dare to practice and took out a black pearl from his spatial space.

He threw it at the Tusk Pig.
