In the afternoon, Xu Xian stood in front of the half-collapsed manor building, and his face couldn't help but be a little speechless.

The research of the phoenix hairpin is really dangerous, Xu Xian just made a real balloon preliminarily, and it actually burst directly, and its structure was extremely unstable.

"It should be that my true qi line is still too thick, which causes the final formed structure to squeeze each other, so it is impossible to control stably at all. ”

Xu Xian quickly found out the reason, but this problem was not easy to solve. If he wants to improve, unless he is willing to invest another 5 XP to upgrade the True Seal to "Advanced".

On the other hand, simulating the true qi structure of the phoenix hairpin is indeed quite amazing.

Just such a sketched version can produce this level of explosive effect, and if a way to stabilize the structure can be found, this will become another weapon in Xu Xian's hands.

Moreover, the group killing ability of this method is irreplaceable by Xu Xian's other abilities, and Xu Xian estimates that it is difficult to have alternative means before he is promoted to innate.

"This explosive True Qi structure, it might as well be named True Qi Explosive Bomb, but unfortunately it requires a high-level True Seal to be used stably......"

Xu first named it, and then couldn't help but feel a little itchy.

It only takes 5 experience points to upgrade the True Seal again, but Xu Xian also has a plan to save money to upgrade Zhou Tiangong.

It is really difficult to choose whether to save money to complete the improvement of the Great Realm, or to convert the existing funds into instant combat power...... Forget it, if you have money, you have to spend it, you can't be a miser!

Xu Xian only hesitated for a moment, and then quickly made a decision.

The battle with Nie Yunfeng in the morning made Xu Xian, who had been a little complacent recently, realize that he was far from being invincible in this world.

Even Nie Yunfeng could cause him trouble, let alone the heads of the major forces.

In this case, instead of having some money to spend in an accident, it is better to use it to strengthen combat effectiveness, Xu Xian doesn't want to keep the money to buy a coffin.

What's more, the ascension of the True Seal may also have an effect in the Innate Realm, and it is not a waste.

Thinking of this, he made a lot of excuses for himself, and never admitted that he was just afraid of death, so he didn't hesitate to start investing in experience.

"For 5 XP points, the skill 'Intermediate Binding True Seal' has been upgraded to 'Advanced True Binding True Seal'. ”

The money had already been spent, and Xu Xian didn't have the slightest entanglement left in his heart, and quickly began to familiarize himself with the ascension of the True Seal, and then refined the True Qi Silk Thread.

As Xu Xian expected, after the True Seal was promoted to "Advanced", not only did he improve his manipulation of True Qi to a higher level, but he could also easily draw a more subtle line of True Qi.

Xu Xian sat down again, and the unfamiliar handprint in his hand quickly formed again, and he was much more proficient than the first time.

A short time later, a new True Qi Explosion Bomb took shape, but this time it remained in the air and did not explode at the first time.

Xu Xian simply stood up, maintained the True Qi Silk Thread with one hand, and began to try to move with the True Qi Explosion Bomb.

Surprisingly, just by refining the True Qi Silk Thread, the entire structure seemed to have been tempered and became extremely stable.

Not to mention walking, even if Xu Xian ran quickly, jumped, or even used the upper cloud step, he couldn't make this True Qi Explosion Bomb collapse.

But correspondingly, the overly stable structure also reduced its power, and according to Xu Xian's estimate, this explosive bomb was only about half the power of the previous one.

"In this world, I am afraid that there is really a Dao Sect, and it is a very long inheritance...... This kind of structure, which is extremely stable, is by no means something that a few people or even generations can study. ”

At this point in the experiment, Xu Xian couldn't help but sigh in his heart, he felt that he was gradually unveiling the veil of history, and this world was obviously not as he understood it now, completely devoid of the old history of the previous dynasty.

He casually threw the True Qi Explosive Bomb forward, but a figure suddenly appeared and took the explosive bomb casually.

The explosive bomb that was originally urged by Xu Xian and was about to explode completely was covered by layers of true qi in this person's hands, and finally disappeared into invisibility.

This method of holding down the bomb almost by force is that Xu Xian is also moved by the depth of his true qi.

He looked up, and sure enough, it could only be one person who would appear here at this time-Xu Wenjing.

"With just relying on the phoenix hairpin, you can learn a Dao technique that is close to the formal level, and your True Seal is already stronger than mine. She looked at Xu Xian with a smile in her eyes and said slowly.

After Xu Wenjing showed such a hand, the fatigue on her face seemed to be heavier, and the whole person looked far less heroic than before, but a little delicate.

Xu Xian looked at her a little strangely, he knew that this woman had a lot of secrets hidden in her, and at the same time, he could see at a glance what kind of state she was in.

"You seem to ...... It's hard to endure?"

In Xu Xian's eyes, Xu Wenjing was now like a kettle about to boil, trying to press the lid to prevent the steam from escaping.

The moment he made a move, Xu Xian was able to perceive the tip of the iceberg, which was a huge amount of true qi that could almost burst people, and it was also thanks to Xu Wenjing that she could stand here casually.

"You can see it. Xu Wenjing shook her head and said, "My mind is incomplete, and I am only afraid that a rash promotion will affect my future cultivation, if you also take this path, don't rush to be promoted." ”

"Which way?" Xu Xian was a little confused.

Xu Wenjing stared at him quietly for a while, and then said with a smile: "I thought you learned the Demon Gate Mind Method by accident, but it turned out to be really Zhou Tiangong...... Zhou Tiangong is orthodox, and it doesn't hurt to practice it. ”

Xu Xian is not a fool after all, hearing Xu Wenjing's words, combined with Nie Yunfeng's performance in the morning, he suddenly realized: "Yunshui Jue and Demon Gate Internal Strength can be practiced together?"

"More than that. Xu Wenjing said with a tired face, "The combination of the four mental methods of the righteous path is the whole picture of this exercise, and the six demon skills of the demon gate are the road to promotion." ”

Xu Xian couldn't help but sneer: "It's really generous." Therefore, the so-called Four Righteous Path Sects and the Demon Gate were actually established by the same group of people...... Daomen?"

Xu Wenjing nodded and said, "To be precise, it is the Holy Land in the Heart of the Lake, and the Imperial City is just their spokesperson." I don't know exactly what you want, but with nothing more than power and knowledge, I think we should be able to cooperate. ”

"How to cooperate?" Xu Xian asked with a chuckle, he only cared about what he could get, and if he didn't give enough price, Xu Wenjing didn't expect him to do anything at all.

As if seeing Xu Xian's thoughts, Xu Wenjing just smiled and said, "I don't need you to do anything, as long as you stay here and watch Qifeng Tower fall." ”

"If you can, take a copy of their minds. This is for your own reference and will be beneficial for your future promotion. ”

Xu Xian looked at her silently for a while: "I'll think about it." Listen to you, you're not going to stay here?"

"Of course. Xu Wenjing smiled mysteriously, stood up again, and walked slowly outside the manor, "What I want is the four factions of the mind, what's the use of only one Qifenglou?"

"It's been delayed for so long, and it's time for reinforcements to come. ”

As soon as the words fell, her figure had disappeared, and Xu Xian suddenly woke up - this woman...... Take advantage of the other sects to rescue Qifenglou, and go to their hometown single-handedly!

What a return to the carbine!
