"Who the hell is that? Even if he is crushed under the tower, he still has to protect the people in the city, but you said that if you let him out, more people will die, this is too contradictory!" For Xu Hao's words, Yun Zhan was obviously puzzled.

"The reason for this, I really can't say more to you, otherwise it will be harmful!" Xu Hao said: "And I am so anxious to find you, it is for the one under the tower!"

"Oh!?"

"There is a large array under this sword-casting tower, called the Blood Soul Trapped Demon Great Array, which is based on the powerful soul of the twelve-headed demon clan, forming a large array to suppress that one under the sword-casting tower!"

"Hiss!" Hearing Xu Hao's words, Yun Zhan suddenly gasped, taking the powerful soul of the demon clan as the cornerstone, you must know that the demon clan is famous for its natural strong soul, and basically has natural supernatural powers, which can extract the soul of the demon clan's power and form a large array, this is really not a small stroke!

I only heard Xu Hao continue: "But this Blood Soul Trapped Demon Array has a great drawback, that is, if you want to keep the soul as the cornerstone intact, you need to keep it watered with fresh blood every day!"

"That's why you will build the Sword Forging Tower in this Black Rock City bordering the Northern Wilderness, so that you can hunt desolate beasts and obtain fresh beast blood every day!"

"That's good!" Xu Hao nodded: "Actually, I'm just acting on orders, responsible for guarding this sword-forging tower, it only takes another half a year for someone to come and take turns with me, and then I won't have to suffer from this drudgery anymore!"

Xu Hao said, stretched out his hand and pointed to the soul stone behind him, and continued to Yun Zhan: "But this sword-casting tower has been built for more than a year, and the one under the tower is basically going to make trouble every three or five times, and the soul stone that is the eye of the formation has already cracked, plus the commotion last night, the crack of this soul stone is getting bigger and bigger, I'm afraid that the one under the tower will be able to break out of the formation without waiting for the person who will replace me!"

Yun Zhan looked in the direction he pointed, and sure enough, he found that on the soul stone, in addition to the artificially carved blood groove, there were also some cracks, shaped like spider webs, Yun Zhan had not noticed it before, but now this crack was extremely eye-catching.

According to what Xu Hao said, it will take another half a year before someone will come to replace him, and according to this rupture speed, in half a year, I am afraid that the soul stone that is the eye of the array has been shattered into slag, and as soon as the eye of the array is broken, the blood soul trapped demon array under the tower will naturally collapse immediately, if the one who was suppressed under the tower escapes from the predicament, Xu Hao, who is in charge of guarding, will definitely not escape the responsibility.

"So, I need you to do me a favor!" Xu Hao said seriously.

"What's busy?" Yun Zhan asked.

Xu Hao replied: "I have to replace this soul stone, but in the process of this replacement, the blood soul trapped demon array under the tower will be out of sight, and that person will definitely take advantage of this time to try to break out of the formation, so I want you to go to the bottom of the tower to temporarily preside over the big array!"

"Presiding over the Great Array?" Yun Zhan frowned and said, "I only have the strength of the four or five heavens the day after tomorrow, how can I afford this kind of heavy responsibility!"

Xu Hao shook his head and said: "If you want to preside over this Blood Soul Trapped Demon Array, it has nothing to do with strength, the most important thing is that if you want to preside over this Great Array, you need extremely strong spiritual power." ”

"Once this soul stone is touched, it will absorb spiritual power, and as long as ordinary people touch it, they will be sucked dry. But the first time you came, you accidentally touched the soul stone, but there was no discomfort, which shows that your mental power is extremely strong, enough to control the Blood Soul Trap Demon Array for a short time!"

"If you have strong mental power, you can preside over the big array, then why don't you ask the city lord to help, he is a real swordsman cultivator, and his spiritual power will definitely not be bad!"

Xu Hao said seriously: "It stands to reason that he can barely control the big array, but my Sword Casting Valley is located in the Eastern Dynasty, although there is no grudge with him, the Northern Dynasty, but after all, it belongs to two countries, and he has to be guarded against, that is, when he reached an agreement with him, when he built the Sword Casting Tower here, he was never told that there was a big man pressing under the tower, how could he ask for help at this time!"

"As for you, I don't have to worry about this, I have already figured out your bottom line, and I am still very relieved of you!" Since he has a request for Yun Zhan, Xu Hao will not hide it, and directly open the skylight and say something bright.

The so-called obedient and listening, although Xu Hao did not have any threatening words, but just the sentence 'I have already figured out your bottom in detail', Yun Zhan had to agree, if he refused, it was difficult to guarantee that Xu Hao would not do anything, after all, any of his is responsible for guarding the sword tower, if the one under the tower escapes, Xu Hao will definitely die, for his own life, even the saint may have to use some extraordinary means!

"It's no problem to help you, but I haven't even heard of this Blood Soul Trapped Demon Array before, let alone host!"

"What's more, you said that the one trapped under the tower is so terrible, saying that as soon as he comes out, countless people will die, he must be an extremely terrible big devil, I will help you preside over the big array, I will definitely offend him, if he escapes one day, then I will be in big trouble!"

"You kid!" Xu Hao smiled and said: "I am not satisfied with giving you so many benefits before, don't think that Lao Tzu doesn't know, I asked you to send the Xuantie Sword to the City Lord's Mansion before, and the bounty will definitely not be less than 100 gold, so much gold can't satisfy you, your kid's appetite is really boundless!"

"Damn, you've already made up my mind!" Yun Zhan scolded.

"But who asked Lao Tzu to ask you!" Xu Hao said, took two booklets from the side, threw them to Yun Zhan, and said: "Here, there is a soul refining recipe and a "Sword Pattern Catalogue", any of which is worth 10,000 gold, which can make you watch it for a day, as for how much you can learn, it depends on your own creation!"

- Soul Refining Technique!

Yun Zhan opened one of the volumes and looked at it carefully, this is a kind of soul refining technique, which strengthens people's spiritual power by repeatedly tempering the soul like a sword.

However, the level of this so-called soul refining technique is still too low, even if it is practiced, the spiritual power that can be enhanced is extremely limited, Yun Zhan has now condensed the initial Dao fetus in the divine court, and the spiritual power that can be mobilized has far exceeded, the limit that this soul refining technique can reach is that this soul refining technique is of no use to Yun Zhan.

- "Sword Pattern Catalogue"!

This is worth Yun Zhan's careful study, after all, Yun Zhan is still very interested in sword casting, not to mention anything else, just the ten thousand sword techniques he is cultivating now, he needs to constantly devour the essence of the sword, if he can become a sword caster, it will also be of great benefit to cultivation.
