After Ye Qing killed Yulong childe, he soon heard a prompt sound from the system.
"Ding, congratulations to the host. The super large and strongest King's treasure chest has been detected. Please pick it up as soon as possible!"
Ye Qing listened to the sound of the system and burst into a bright smile. Sure enough, a treasure chest appeared where the prince Yulong disappeared.
According to the rules of the system, the more powerful the enemy is, the higher the probability of exploding the treasure chest is.
Ye Qing killed the peerless Tianjiao Yulong childe and it's reasonable to get the treasure chest.
Stepping out, Ye Qing walks to the location of the treasure chest and opens it easily.
"Ding, congratulations to the host for opening the super large and strongest King's treasure chest and getting special items, millions of killing gas!"
Hearing the prompt sound from the system, Ye Qing suddenly felt a million killings in her heart. It sounded like a cow.
"Just right, my immortal killing sword still needs killing Qi, so it can be used to improve the quality of immortal killing sword!"
As soon as Ye Qing's eyes brighten, the magic weapon Zhu Xianjian obtained before is very special. It can be upgraded by swallowing the killing gas and continuously improving the quality.
Up to now, the immortal killing sword has become the best artifact with great power.
Of course, Ye Qing already has a lot of half step research artifact and power stone in his hand. It's a real research artifact, and he doesn't care about the best artifact.
Millions of murderous Qi may make the immortal killing sword sublimate into a supreme artifact!
The so-called killing gas of millions is the killing gas generated by killing millions of creatures. Under normal circumstances, if ye Qing wants to upgrade the killing immortal sword, he needs to carry the killing immortal sword and kill himself.
But when the treasure chest opened, it was much easier to kill.
It is reasonable that the killing gas cannot be stored. If it is not absorbed after killing, the killing gas will dissipate.
However, the strongest King's treasure chest opened by the system is so magical. It is the existence of opening and hanging, which directly provides the gas of killing millions.
With a move in mind, Ye Qing took out the immortal killing sword in the system space. Speaking of it, he hasn't used the immortal killing sword for a long time, mainly because the quality of the immortal killing sword is not enough and can't keep up with his rhythm.
In fact, if the quality of Zhuxian sword is improved, it will be more powerful than many artifact of the same quality.
A magic sword growing up in the killing can never be underestimated.
With a "hiss", Ye Qing offered up the immortal killing sword, blooming a red light, suspended in the air.
Around the immortal killing sword, there was a lot of killing gas. A sea of corpses and blood was formed in the sky, and the towering smell of killing filled the holy medicine island.
The Tianjiao people on the holy medicine Island were stunned. Such a terrible killing gas suddenly came out of nowhere. It was so frightening.
"My God, why is there such a terrible killing after the death of Prince Yulong?"
"I don't understand. I really don't understand. Don't those murderous Qi come from Yulong childe, but something else?"
There was a sound of discussion on the holy medicine Island, and people were staring at each other.
At the next moment, the bloody long sword suspended in the air blooms with an extremely strange luster. After absorbing the killing gas, the sword body vibrates continuously and makes an amazing buzzing sound, which seems to be undergoing some transformation!
"Look, why can he bring artifact into the stadium?"
"When I went, did you find that he had an artifact? I don't know how he lied to the world. Anyway, I'm not surprised." Liu Dali said.
Last time they were trapped in Noah's ark, Ye Qing left with a glittering Ruyi golden cudgel.
Artifacts cannot be used in the battlefield of thousands of countries. This rule is meaningless to Ye Qing. His artifacts can be taken out at will.
"Look, that sword has a strong killing smell, and it seems to be sublimating!"
The crowd was even more frightened. They almost fell off their chin. The scene in front of them was too shocking.
It is conceivable that it is difficult to sublimate the best artifact into a research artifact. It requires a lot of precious refining materials and a world-famous refining master to have a certain possibility of success.
Ye Qing didn't use any refining materials at all, but let the bloody long sword absorb some killing gas and was about to sublimate.
It's a lot to say about millions of killing gas, but after opening the treasure chest, the killing gas continues to escape, and it's estimated that less than 50% of the killing gas really left to be absorbed by the killing immortal sword.
The speed of killing Qi absorbed by the immortal killing sword has been very fast. However, the killing Qi dissipates faster than expected.
Just two minutes later, there was little killing in the sky.
The immortal killing sword trembled violently, and a clear sword sound was transmitted.
With the sound of "buzzing", the immortal killing sword chirped violently, and the next moment, the killing gas in the sky completely dispersed, and there was nothing left.
There's no way. The process of killing Qi absorbed by the immortal sword was forced to stop. It's too difficult to absorb all the killing Qi.
Ye Qing's body moved, his hands were full of killing Qi, and his eyes were full of brilliance. Although the current immortal killing sword could not be sublimated into an extreme artifact, it had actually been half successful.
After absorbing a lot of killing gas, the immortal killing sword has become a half step research artifact, which is more than ten times more powerful than before!
Holding the immortal killing sword, Ye Qing seemed to see the scene of Shura Xuehai. The immortal killing sword born in the killing was really powerful!
Later, Ye Qing had another magic weapon around her.
He raised his mouth slightly, thought of the Dragon killing knife, and then turned his eyes to those ancient star dragons.
To improve the quality of dragon slaughtering Dao, it is very simple. Just let dragon slaughtering Dao absorb dragon blood.
Ye Qing is reluctant to release his own dragon blood. The blood of the supreme Dragon God is too precious.
The blood of those ancient star dragons is very suitable. For today's Dragon killing knives, it is enough to absorb the dragon blood of the inferior Tianlong and ancient star dragons.
"Hey, you nine dragons lie down to me. Don't move or defend!"
Ye Qing sent out a divine idea, and then offered a dragon killing knife.
A bright knife lights up and cuts at one of the archaic star dragons.
Just listen to the bang, the Dragon killing knife bounces out, and the Taigu Star Dragon is unharmed.
Ye Qing frowned slightly. It seems that the Dragon killing knife is still too weak to break the skin of the ancient star dragon.
Those ancient stars and dragons are in fear. They know that Ye Qing's intention is to want their blood essence. The problem is that they have no defense, and the knife can't hurt them, which is very embarrassing.
"What are you doing? Spit out a mouthful of blood essence!" Ye Qing ordered again.
The nine ancient star dragons all have a black face and some are speechless. They spit out a mouthful of blood essence?! It was the first time they had heard such a strange request.
