Seeing that Shenyun affirmed his words, Bai Yufan also nodded slightly, and then he asked again, "I don't know what the requirements for elemental power are for this test?"

Shenyun saw that some people didn't know the requirements for testing the elemental power, and his expression became strange, but he didn't show it, but continued to say to Bai Yufan: "This requirement, the first thing to test is the purity of your elemental power, some people have cultivated the elemental power of the Xuanwang and are not very clean, but some people are just a Xuanshi, but the elemental power in the body is extremely pure." Of course, if you have multiple elements in your body, you can also do a different story. ”

After listening to Shenyun's narration, Bai Yufan also fell into a state of thought.

Stygian thought that Bai Yufan was thinking about how pure his elemental power could be, but what he didn't know was that what Bai Yufan was thinking about at this time was how to keep a low profile.

After a moment, Stygian asked, "Are you ready?"

Bai Yufan nodded, at this moment he already had a simple idea in his heart.

Then, Shenyun took out a disc-shaped quaint stone from his cuff, and he couldn't feel any spiritual power fluctuations on this stone at all, Bai Yufan felt that this stone was very familiar, but he just couldn't come up with this kind of material, he had seen it there.

Looking at Bai Yufan's confused look, Shenyun stroked his beard and said to Bai Yufan: "This stone was brought back from the extreme cold by the ancestors of our Black Smoke Chamber of Commerce, and when the meteorite fell that year, our ancestor used his storage ring to bring back two outer meteorites, one was used to cast the spirit stone outside the door, and the remaining materials were used to cast this spirit stone, and at the same time, he also added a special material to it, now you see that this stone is just an ordinary stone, and you will know its magic later!"

Fate didn't explain anything, just with a slight wave, the stone seemed to be conscious, and it froze in mid-air, and the ancient tower seemed to feel some kind of call at this time, and suddenly released a boulder from its handle that was exactly the same as the outside of the door, but the back of this boulder was not engraved with the black smoke chamber of commerce, but a big "Luo" character.

Bai Yufan, who saw this scene, also knew that the spirit stone in the hand of the dark cloud should be a key, and this formation could only be awakened through special methods, and once this formation appeared, it could call out the huge spirit stone, and the one in his hand was just a disguise.

Shenyun didn't talk nonsense with Bai Yufan, but just told him to release his spiritual power on this spirit stone to his heart's content.

Bai Yufan didn't hesitate either, he directly released the power of the fire element in his body, and suddenly a blazing ice blue flame smashed directly on this huge spirit stone.

However, the attacked spirit stone showed no signs of being destroyed, but as Bai Yufan's spiritual power was released, its color became more and more vivid, from black to red, then to yellow, and then to cyan, and finally if it wasn't for Bai Yufan who could mix the elemental power he released with some water elemental power, then this boulder should have properly turned purple.

Moreover, what Stygian Cloud didn't expect was that with the release of Bai Yufan's water element, this boulder actually wavered a little.

Suddenly, Stygian's heart was shocked, since he was in charge of this spirit measuring stone, there had never been such a strange phenomenon. Suddenly, something seemed to be in his mind, so he hurriedly put away the spirit measuring stone and said to Bai Yufan: "This spirit measuring stone has been eroded by too much elemental power and has become a little incomprehensible, so let's go in first and talk about it again!"

Bai Yufan didn't have much to do, he only knew that his spiritual power was mixed with each other and released, if he simply released an element, then I'm afraid that this spirit stone might not be as simple as erosion.

So, he turned around and walked towards the Foreign Trade Pavilion that slowly opened the door of the tower.

But Shenyun was not as good as him, although he walked behind Bai Yufan, cold sweat kept oozing from his forehead, because the reaction of the spirit measuring stone before was to recognize the meaning of the master! When their ancestors created this spirit-measuring array, they invited the most mysterious organization in the world, Guigumen, to make a prediction for them, that one of the Guigu masters, the eyes of this soul-measuring array have been waiting for a person, before this person came, this formation can be used for a long time, but if this person really comes to talk, not only will this array take the initiative to recognize the master, but their black smoke chamber of commerce will also undergo a slight change, plus the three helmsmen have recently made trouble because of the matter of succession, as well as the boiling Bai Yufan, all of which made Shenyun's heart a little worried。

But Bai Yufan didn't know these things, and when he entered this Foreign Trade Pavilion, he was constantly looking at these ancient towers that were regarded as treasures by the Black Smoke Chamber of Commerce at this time.

Although this ancient pagoda looks thousands of years old, it is spotless inside, Bai Yufan looked around at these treasures, but they all shook their heads, none of them were what he looked at.

Seeing Bai Yufan's appearance after seeing the baby, Shenyun was also surprised, because the Xuan who came here, don't be on the first floor, even if he first entered the door, he couldn't suppress the joy in his heart, whether it was Emperor Xuan or Master Xuan, there were many dreams of going to the Foreign Trade Pavilion of the Black Smoke Chamber of Commerce to see, but now although Bai Yufan came in, he was not cold to these treasures at all.

"Ahem, Bai You, you may not be very interested in the things here, so why don't you follow me to the top floor to have a look?" After seeing the reaction of the spirit test stone and thinking of the previous language, Shenyun's attitude towards Bai Yufan also changed subtly, and now he no longer regards Bai Yufan as a young man, but in his eyes, Bai Yufan's every move may affect the life and death of the Black Smoke Chamber of Commerce in the future.

Bai Yufan didn't speak, just nodded.

Seeing that Bai Yufan agreed, this dark cloud also waved his hand, and a powerful spiritual power took Bai Yufan directly to the top floor.

From this spiritual power of his, Bai Yufan could judge that this dark cloud must at least be at the Xuan Saint level, because only at this level can he carry out spatial shuttle, and as for the ability of Wei Jian Zhuang to be able to spare the sin in the air, at least it must be done at the emperor level.

Suddenly, Bai Yufan's attitude towards this dark cloud also became respectful.

But before he could speak first, this dark cloud spoke: "Bai You, I can be the master today, you can choose any one of the treasures on the top floor of this foreign trade attic, and it doesn't cost a penny!"

But what he didn't expect was that Bai Yufan actually said: "Isn't this place just a random choice without spending money?"
