Little brother, you're finally here!"

After arriving at the City Lord's Mansion, Bing Yan saw Xingyun come out to greet him in person, and Wusi naturally accompanied him.

"Lord of the City, this Flame Crystal Secret Room ......"

"I'm ready, come with me. Before Bingyan finished speaking, Nebula went over with Bingyan, and Uss followed.

After that, they arrived at the inside of the City Lord's Mansion, and under the leadership of Xingyun, Bing Yan came to a large room, where they finally saw this Flame Crystal Secret Room.

It was a hermetically sealed structure made of fiery red hedrons.

This Flame Crystal Secret Room occupies a small area, and its volume can only accommodate one person barely entering it. It's not so much a secret room as a larger chest.

However, Bingyan was not very surprised by such a secret room. He himself also knew very well that Yan Jing was very expensive, and he would definitely have to save as much as possible to use it to build a secret room, and it was normal for the space to be so small.

"Brother Bingyan, this is the Yanjing Secret Room, although it is indeed a bit small, it can still be used!" Xingyun smiled awkwardly, obviously a little embarrassed.

After seeing this shabby Yan Crystal Secret Room, he didn't dare to imagine how this Bing Yan looked at him, the city lord.

"Let me go in and try it. ”

Bingyan didn't care too much about this, this size was already in his expectations, how could he be angry.

"Brother Bingyan, if you can't bear it, you must come out immediately! There is a high temperature of 500 degrees inside!" Xingyun said with a solemn expression.

Generally speaking, a ninth-level magician with full firepower can withstand the high temperature of about two thousand degrees in an instant, but that is only for an instant. Going in to cultivate is another matter, going in to cultivate is something that lasts for a few hours, and it can't be solved by relying on a momentary outburst. The difference here is like a sprint and a long run.

And when resisting the heat, there is still the distraction to concentrate on cultivation, which is the most difficult.

"It's okay, I can't stand it, I'll come out. ”

The corners of Bing Yan's mouth hooked up a smile, he had long been familiar with Yan Jing's thing, and there was nothing strange in his heart.

"Then you must come out, I have set a button inside, as long as you can't stand it, press that button, and the door of this secret room will open automatically. Nebula continued to explain.

As a magician, he naturally knew the abilities of a ninth-level magician, and according to his estimate, even a fourth-level ninth-level magician would not be able to stay in it for more than half an hour. And Bing Yan didn't even have a single ring of cultivation, so it is estimated that he will last for eight minutes, and if he has some perseverance, he may be able to do it in ten minutes.

"Yes, Bingyan, don't be reckless. Uth also admonished on the side.

However, his thoughts were a little different from those of Xingyun, he felt that Bingyan had such a big background, and he should have cultivated a very powerful magic secret book, which could not be measured by the standards of ordinary magicians. According to his estimates, Bingyan might last in for ten minutes, or even fifteen minutes.

"Thank you for your concern, if I can't bear it, I will press the button as soon as possible. ”

Bingyan nodded, but he wasn't too worried. His current magic cultivation is not comparable to ordinary ninth-level magicians at all, and now even if he doesn't use dragon blood, he has the strength of the four rings, not to mention the dragon blood fire and the dragon pattern in his body.

A heat wave of 500 degrees is nothing to him.

"Okay, I'm going to open the secret room, and when the secret room is opened, I will activate the magic array, and then the fire element of the flame crystal will erupt instantly, you have to be ready!" Xingyun continued.

"No problem, just come on!"

After Bing Yan finished speaking, he directly created a magic shield that isolated the outside world, and this magic shield protected the clothes inside, ensuring that they would not be burned to ashes.

After entering, Nebula manipulated it from the outside and directly locked up the Yanjing secret room, revealing only one hole to breathe.

Although there are ventilation holes, the entire secret room is isolated by a magic array, and the fire element inside can't escape at all, and it won't waste the energy inside.

"Three, two, one, the magic array is activated!"

Nebula shouted outside, prompting the ice flames inside to get ready. At this time, Bing Yan had already adjusted his magic shield, just waiting for this flame crystal to emit the fire element.

The next moment, a burst of light flashed, and the entire flame crystal secret room was like an enraged lion, instantly agitated, and a large amount of fire elements erupted from it, mixed with some powder. These powders are flame crystal powders, and this powder will seriously affect the absorption of the Great Sage Mark, which is also the reason why the Great Magician cannot come in to cultivate.

But for the mage of Bingyan, none of this is a problem. He settled his mind and began to absorb the fire element within.

After the magic array was activated, the temperature of the flame crystal secret room also increased sharply, and soon reached the limit temperature, and Bing Yan directly turned into a hungry wolf, greedily absorbing the fire element here.

Previously, in order to let him learn the magic of the field of "Heavenly Fire Prison", Zero specially let him broaden his meridians. Now his meridians were already stronger than ordinary ninth-level magicians, and the speed of absorbing magic elements was naturally far beyond them.

"Cool, cool!"

Bing Yan is like a giant whale, greedily absorbing the fire element here, which is much cooler than the elemental gathering array. After this period of cultivation, he was about to cultivate to the level of the first ring, but after coming in for a few minutes, he actually broke through directly to the first ring and marched directly towards the second ring!

Outside, Nebula and Uss were also guarding outside, holding pocket watches and starting to count the time. But ten minutes passed, and Bingyan still didn't come out.

"This Bingyan is not bad, it can stay for ten minutes. Could it be that his true level has reached a level?" Xingyun was slightly shocked in his heart, it seemed that this ice flame was really extraordinary. But he was only slightly surprised, after all, he was the city lord of Star King City, and the magic geniuses he had seen were not hundreds but thousands, this level could be regarded as extraordinary, not top-notch.

However, as time passed, another ten minutes passed, and Nebula's heart gradually set off turbulent waves, and even Uss began to be a little uneasy.

Counting the previous ten minutes, it has been a full twenty minutes, which can only be done by the three rings, but Bingyan still persevered.

Unbeknownst to them, this was just the beginning.

After another ten minutes, Nebula and Uss were completely dumbfounded, and after another half an hour, they looked directly at the pocket watch in their hands, thinking that something was wrong with the pocket watch.

"Us, he's been in for an hour, hasn't he?" asked Nebula with a look of disbelief.
