"Gu Xuan, are you sure?" Lin Lao looked at Gu Xuan with a face full of suspicion.

Ying Tian Sect had only risen for a hundred years, so the time it had existed was even shorter. Back then, Lin Lao was the academy's Sovereign Level teacher, so he naturally knew what Tongtian Tower it was.

Tongtian Tower was the will that transcended the heavens, and to be able to pass through it, was to reach the heavens, the creation of Sect Master Mo Jingyun.

The establishment of Tongtian Tower was originally an assessment of truly talented disciples, but due to Sect Master Mo Jingyun's talent, the conditions he set were naturally very harsh. Back then when the Tongtian Tower was established, nearly all of the students were unable to pass the first stage.

Mo Jingyun gradually lost interest in Tongtian Tower as well. In the end, as Ying Tian Sect gradually grew stronger, the quality of the number of geniuses steadily increased and there were a few true geniuses who could pass through Tongtian Tower. However, because the number was still too small, every single one of them flashed with light.

Over time, the Tongtian Tower was also completely abandoned.

Surprisingly, none of those students with Yingtian Institution knew of the existence of the Tongtian Tower.

"I'm sure. Senior, please notify Patriarch Violet Wind." Gu Xuan nodded indifferently.

"Alright." The Lin Lao nodded, but still sighed. He seemed to have understood Gu Xuan's intentions, because the academy had dealt a blow to his judgement, wanting to prove himself anew. Thus, he chose Tongtian Tower.

He wanted to use his Tongtian Tower to prove himself.

However, if Tongtian Tower were to be that easy, then it would not be abandoned and be used. It was very possible that Gu Xuan would be eliminated the moment he entered the first floor, and by then, the impact he would receive would also not be small.

Of course, the most likely scenario would be that the Martial Ancestor Zi Feng would reject Gu Xuan's request.

Opening the Tongtian Tower once would consume a large amount of Spiritual Crystal and if the number was converted to Treasure Point, there would probably be around two to three hundred thousand Treasure Point. Even before Tongtian Tower were widely used, Tongtian Tower could not be activated as they wished.

Would the Academy be willing to spend several hundred thousand Treasure Point to give Gu Xuan a chance that could not be considered as an opportunity?

Lin Lao left while the rest still did not quite understand what was going on. They had never even heard of Tongtian Tower before, but looking at the reaction of the people from Lin Lao, it should not be that simple either.

As for Su Tianxin, after hearing the Tongtian Tower, he started laughing coldly. Her master was called Celestial Shadow Martial Ancestor, so she knew a lot more things than most people. Once, she was extremely confident in her talent, so he was a little too proud and indulged in it.

And Gu Xuan actually wanted to challenge the Tongtian Tower? In her eyes, this was simply boasting too shamelessly …

In a corner of Ying Tianshan, in a pavilion that was built independently, Zhou Juechu sat on a chair. Beside him stood a man in a white robe.

"Master, I've already made inquiries. Gu Xuan indeed killed a hundred third level Flame Beast in a month's time." The green dragon messenger said respectfully.

"This Gu Xuan is interesting." Zhou Juechu raised his eyebrows and sneered: "But what use is that, it only proves that he is worthy of fifty thousand Treasure Point, and that it is only half worth it?"

Ever since Gu Xuan was requested by the academy to complete his mission, Zhou Juechu no longer held any hostility towards Gu Xuan.

Therefore, even if Gu Xuan were to kill a hundred Flame Beast within a month, it would only serve to make him pay attention to it.

"Master, aside from this, there is another thing." The Azure Dragon Emissary said respectfully.

"What is it? Speak." Zhou Juechu said casually.

"Gu Xuan is requesting for the Tongtian Tower Assessment?"

"What?" Zhou Juechu seemed as if he didn't hear it clearly, and immediately after, he laughed wildly, as if he had heard an enormous joke.

Even though he had never gone to the Tongtian Tower before, as one of the top geniuses, he had paid attention to the few geniuses who had successfully passed through the Tongtian Tower before.

The first level of Tongtian Tower was the most difficult. As long as one passed through the first level, as long as they passed through the second level, it would only be a matter of time before they reached the fourth level.

Fifth Layer was also a threshold. Being able to pass through Fifth Layer meant that one was an absolute genius, even within Ying Tian Sect.

"Even I can't pass the Tongtian Tower, what does he, Gu Xuan, count as!" Zhou Juechu let out a cold snort...

Lin Lao walked all the way to the Monument, when he finally opened his eyes. He asked indifferently: "Junior brother Lin, what do you want? I thought you said that the Evil Spirit True Fire's guards have recently reached the most critical moment, so it's not really anything major.

"Patriarch." The Lin Lao said somewhat helplessly, "If it was any ordinary matter, I definitely wouldn't disturb the Ancestor. It's just that this time, someone wants to start the Tongtian Tower Assessment."

"Humph!" Martial Ancestor Zi Feng's face sank as he said with a sneer, "I didn't expect that there would still be people who are wishful thinking. Not many people would be able to pass the Tongtian Tower within a hundred years, and five million Spiritual Crystal would be required to open it every time for him alone? "I refuse."

"Fine." Lin Lao nodded his head helplessly. In fact, he knew from the beginning that there was no possibility of getting an agreement.

Although the background of Yingtian Institution was abundant, most of it was allocated to many teachers and Sovereign Level students, at most, there would be some more special Profound Level students.

If the price was small, it might not be so simple if it involved the huge affair of millions of Spiritual Crystal.

"Then I'll take my leave." The Lin Lao bowed respectfully towards the Martial Ancestor Zi Feng, then turned and walked out.

"Wait!" Martial Ancestor Zi Feng seemed to have thought of something, and asked, "Who is that person?"

Lin Lao was startled, but in the end, he still said: "It's Gu Xuan."

At this moment, Lin Lao had already started to mourn for Gu Xuan. His attitude towards Gu Xuan was originally not good, but after this incident, it would probably get worse.

"Oh?" After hearing Gu Xuan's name, the Martial Ancestor Zi Feng could not help but be somewhat surprised. He nodded and said: "Since it's Gu Xuan, then let's give him a chance.

Lin Lao's mouth was wide opened, and he felt a little dizzy. He really couldn't understand, whether the Purple Wind Grandmaster admired and disdained Gu Xuan or not.

If it was out of disdain, then millions of Spiritual Crystal had been casually used as well. But if it was out of admiration, there was even a condition attached to the chance to refine a Evil Spirit True Fire, what kind of admiration was this?
