The spirit card itself may not have any effect, but in this killing sky, the spirit card plays a crucial role, which is related to whether it can survive.

Therefore, every spiritual card I obtained now is a life-saving thing. If it can be more, it will be more. Therefore, the three of them did not stop and continued to look for the next stone gate.

Boom boom boom boom!

Xiao Yan and the other two were so powerful that they blasted open three stone gates in a row, but as they went deeper, the demon spirits in these stone gates became stronger and stronger. However, with the joint efforts of Xiao Yan and Lei Ji, killing them was not a big problem.

Next, Wu Zhen became a mascot that was specially unboxed. He did not disappoint everyone's expectations. One hundred green spirit cards were drawn from three stone boxes in succession. In addition, Xiao Yan had 150 green spirit cards in his hand.

However, such a quantity is obviously just a drop in the bucket. Fortunately, it is not too difficult to obtain the spirit card, and it exists almost everywhere in the killing world.

But a purple spirit card requires one hundred blue spirit cards, that is to say, a purple spirit card requires one thousand green spirit cards. Although it is easy to obtain, when you carefully calculate this number, you will understand that the difficulty is quite considerable.

It is precisely because of this that the competition between spiritual cards will become more and more intense as the killing aura continues to shrink, because only those who hold purple spiritual cards and spiritual keys can survive in this killing aura.

You should know that this is the first level of killing the sky. Keep going up, and the second level or even the third level is very likely. The difficulty will become greater and greater, but the fortune will become more and more terrifying.

Although Xiao Yan has not swallowed the Baiyuan Spirit Fruit he has obtained, the effect of this Baiyuan Spirit Fruit will never disappoint him. Just looking at this Baiyuan Spirit Fruit, you can feel its pure source energy fluctuations.

There is no time or safe place to provide cultivation now, but Xiao Yan is not in a hurry. He will first go out of this ancient palace and then talk about improving the source energy foundation.

In the middle stage of the Five-Star Fighting God, there is a source energy foundation of 1.6 million. Even if Xiao Yan’s double source energy sea can burst out with a source energy foundation of 3.2 million, this amount can no longer cope with the current battle.

If it weren't for Lei Ji and the Immortal Demon Clan, the most important thing was the improvement given by the Ten Absolute Demon Flame, which would be difficult to overcome with Xiao Yan's true strength.

Although the Ten Absolute Demon Flame is very strong to solve the problem of the source energy foundation, Xiao Yan understands that this is not his own real strength. If he meets a stronger person, the disadvantages of the Ten Absolute Demon Flame will gradually be exposed.

Although the foundation is magnificent, it is not Xiao Yan's after all. It is impossible to have the same degree of compatibility as himself, so the improvement of his own strength is particularly critical.

Xiao Yan and the other two were shuttled through the passage, as if they had swept all the stone gates around them. At this time, the three of them passed through the passage and came to a relatively vast space.

"It seems that this is the core!" Xiao Yan looked around and murmured.

Lei Ji nodded slightly and looked over with her eyes. In the air of this space, there were three rays of light floating in it, and Xiao Yan's gaze was immediately attracted.

There are three different objects in the three light groups. The first one is a blue spirit card, with ten. This number of blue spirit cards is already very terrifying, enough to start a battle for the battle.

In the second light ball was a golden key. When Xiao Yan saw this key, he was shocked and immediately took out the golden key obtained from the stone gate. After some comparison, Xiao Yan immediately made a judgment, and the two were exactly the same.

In this way, the golden key opened by Wu Zhen in the stone door stone box is the spiritual key mentioned in Zheng Qing's mouth.

Xiao Yan sighed coldly. If they could put all the spirit spoons in their bag, they would have already obtained two spirit spoons, and the three of them were still missing one spirit spoon. After that, as long as they gather enough spirit spoons, the first killing of the sky should not be a big problem.

Of course, the premise is that it will not be coveted by others. Although the number of spiritual cards is rampant, it is not easy to get enough of a purple spiritual card, so it is absolutely inevitable to compete.

Xiao Yan's eyes slowly looked at the third ball of light. As soon as he looked, Xiao Yan's eyes condensed slightly. It was a red mist, which looked very strange.

"Killing Aura?!" Xiao Yan was a little confused. There were a lot of killing Auras on the outside, and this thing could not appear here. Xiao Yan didn't know what it was, but each of the three light groups had extremely strong temptation.

The light balls are in various directions of the space, and under these light balls, although there seems to be nothing else now, Xiao Yan knows that it is not that easy to get the treasures among these three light balls.

Looking around, it seemed that only Xiao Yan and the others arrived here first. Xiao Yan was still thinking about which one to start, but at this moment, the sound of a violent rushing through the wind came from the distance.

Suddenly, a team led by Gu Ao in the Dongsheng Realm actually arrived here immediately after Xiao Yan.

Gu Ao saw Xiao Yan who had arrived first, and his beautiful eyes slightly raised, obviously a little surprised.

After the two sides looked at each other, Gu Ao's eyes immediately looked at the third ball of light, which was something Xiao Yan didn't recognize, and looked like a killing aura.

"The spirit of killing appeared. If it was swallowed, its strength would definitely increase sharply. This kind of magical object is one of the top treasures in the killing sky!" Gu Ao murmured. Of course, she would not let Xiao Yan hear it. After all, after coming here, looking at Xiao Yan who was not acting, Gu Ao concluded that Xiao Yan must not know this object.

So he was still hesitating to choose which one to choose. Gu Ao immediately snorted coldly, then moved his body and rushed towards the third ball of light.

Seeing this, Xiao Yan narrowed his eyes and murmured: "Although she didn't know what this is, she should know that she chose it directly without hesitation, which means that among these three light groups, its value is the highest."

"Since that's the case... we can't give in!"

Xiao Yan said and looked at Lei Ji. At this moment, Wu Zhen, who was the "mascot", fell out of favor again. Xiao Yan and Lei Ji's Xiao Yan rushed out at the same time and also rushed towards the third ball of light!

"I'll take a step back. I'll only go to this item. All the spirit cards and spirit spoons are given to you. It's good that the well water will not interfere with the river!" Gu Ao did not expect that Lei Ji and Xiao Yan were so tough. Anyway, they would come and snatch it when they saw what she was going to take.
Chapter completed!
