After injecting the professional demon blood for Ye Ren and the others, the amazing performance of the iron cabinet surprised everyone, a dead thing became like a living thing in the hands of the alchemists, which only those hidden refiners have the ability to make a piece of mortal iron into a living thing, but those weapons can be called divine weapons, so based on this alone, everyone was immediately impressed by this group of alchemists.

However, this magic cabinet is magical, and everyone is looking forward to how it should open this impregnable wall, after all, novelty alone cannot solve the problem.

"The magic cabinet is like a demon standing still, with the power of demon blood injection, and then we can provide magic stones, so that the magic cabinet can continuously absorb the demon qi, transform, refine, and finally spew out a strong and pure demon qi, this demon qi is comparable to the demon qi of the second generation of the demon clan! or even a little more refined!" Zhou Fool saw that everyone showed a novelty to the magic cabinet, he was not idle, and quickly explained.

"Then how are you going to inject this demonic energy into this city wall?"

Sha Xin asked softly.

The city wall has the ability to resist, and the demonic qi wanders outside and can't be opened at all, just like the demonic energy has always existed between heaven and earth, not to mention that this is the secret realm of the demon clan, and the demonic qi is all over the dense, and it is one thing to have the demonic energy, when the demonic qi is possessed, it is another problem to inject it into the city wall.

"It's just a little simpler. Zhou Fool ordered two alchemists, and the two alchemists gently pasted the iron cabinet on the city wall, only to see the two alchemists press on the iron cabinet, and the iron cabinet stretched out countless tiny iron claws like living creatures, these iron claws were gently adsorbed on the city wall, and the power of the city wall subconsciously rebounded back could not cause any damage to the iron cabinet.

The iron cabinet was so easily clinging to the wall, and one of the two alchemists pulled out a small box from behind the butt of the iron cabinet, which was tightly tied to the iron cabinet, and the other alchemists kept putting magic stones into it.

Snort!

Just like the sound of oil boiling in an iron pot, the magic stone slowly melted at the moment it entered the iron cabinet, and the last pure black gas traveled towards the iron cabinet, and slowly, the countless iron claws adsorbed on the city wall also began to slowly inject demonic energy into the city wall.

This seems to be an extremely easy and simple process, but it has stumped a current mode of thinking for everyone, at least the countless complex parts revealed by the iron cabinet alone are enough to make people's heads big.

The magic stone is like a mountain and river, rushing into the magic cabinet like a thousand feet, and the demonic qi also envelops the entire iron cabinet, and the various pipes inside the iron cabinet have become even darker, and the countless snow-white iron claws adsorbed on the city wall have also become extremely black, and everyone can see with the naked eye that the city wall is absorbing the demon qi, so not to mention the perception.

The city walls are constantly absorbing demonic energy, like a baby, endlessly demanding.

However, the magic stone is constantly being consumed, but the city wall is still standing still, like a warrior guarding the homeland, which is prohibitive.

"Whew, I'm a little nervous. Qianjing clutched his chest, took a deep breath, and said in a slightly trembling voice: "It should be too badly injured, yes, nothing wrong." ”

No one replied to his words, because everyone was looking at the immovable city wall with bated breath, hoping that a miracle would happen.

"Increase the investment in magic stones. ”

Fool Zhou frowned and said, this city wall was used by the extremely powerful demon clan back then, and the city wall that needed to be opened by them was of course not something that these little magic stones could open.

"My lord, we are using high-grade magic stones, we can't increase the amount, we can only step by step, otherwise the iron cabinet will not be able to withstand such a strong demonic qi at all. Liu Lao said.

"Whew. Fool Zhou took a deep breath, touched his head, turned his body, and made himself no longer look at the iron cabinet, Liu Lao, as the chief alchemist of the alchemist group, no one in this regard weighed more weight than him.

"Wait. ”

Ye Ren broke the embarrassment and said, in fact, the most important thing is that half of the magic stone has been consumed, this is the source of everyone's increasing anxiety, once the magic stone is consumed and the city wall is still standing still, then this plan is equivalent to failure.

"Such a huge amount of demonic qi can't open the city wall, so can the demons who came in before enter it?" Kui Shao asked puzzledly, this huge demonic qi transformation and refining is already equivalent to the entire aura of a Jiedan monk, that is to say, it is equivalent to the entire demonic energy of a Jiedan demon, this demonic qi is not huge.

"This is different, according to our research, and then combined with the records in the ancient books, the city wall should be fused with the formation, and the demon can use the demonic energy to probe into the divine sense, find the core point and open the city wall. Although the iron cabinet we made can be injected with demonic energy, the direction of the demonic energy cannot be controlled, and if these demonic qi want to find the core point, it must be a huge amount, so that the demonic energy fills every point of the city wall, which will find the core and open the city wall. Liu Lao laboriously explained that although the iron cabinet can replace the demon, there is still a difference between the dead and the alive after all.

"Oh my God, the city wall is so huge, how many magic stones are needed to cover every point!" Zhao Lei exclaimed, there was no end to the city wall horizontally and vertically, which seemed a little impossible for him.

"Haha, anyway, this is a plan worth implementing, and we must not give up until the last moment!" Liu Lao said with a smile, and it was estimated that he was the only one present who could laugh, but his laughter also relieved a lot of tension.

"Then aren't we happy in vain!" said Chii with a somewhat dazed mending knife.

"It seems that you are really injured too badly to speak, and you should see a doctor. Gao Bao, who had been silent, finally couldn't help it, twisted up Qianjing, and directly mentioned it to the rear army, having him here, it would only greatly reduce morale.

"Come along, too. Gao Bao suddenly stopped, pointed at Kui Shao and Zhao Lei and said, the three of them are-stirring sticks, plus the three of them are unstoppable, he did this all for the peace of the Dawn Army and the Cangsheng Army.

"No... No, we're not hurt!" Kui Shao and Zhao Lei pointed to themselves and said in surprise.

"Hehe, let's go, you two stinky boys can't spit out ivory from their mouths, don't affect the mood of adults here. I saw two soldiers walking out, and directly dragged Kui Shao and Zhao Lei to the rear to rest.

"Damn, we're so handsome, what do you mean a dog can't spit out ......"

They walked a long way and still heard the arguments and disbelievings of Kui Shao and the others, as for Qianjing, he had long been screwed out of sight by Gao Bao.

"Hehe, let you see the smile. Ye Ren shrugged his shoulders helplessly and smiled, it's not that the three of them can't spit out ivory, it's just that the three of them are real people and like to tell the truth.

"You're getting busy!"

Fool Zhou had long been used to it, so he didn't react, and motioned to Liu Lao to go over and help.

"Hades Xue, can the Hades King help in this regard?" Ye Ren asked hopefully, people always hope to help at such times, after all, it is not Ye Ren's style to be dumbfounded.

"Master, if it is the divine consciousness entering, the Hades should be able to ignore the restrictions of the city wall on people and demons, but even if the divine consciousness enters, because the demonic qi is ownerless, you can't control it at all. Stygian Xue said euphemistically.

After all, this is an aura, which can be controlled at will, so in this regard, the Hades King can't help much, unless he uses D-level energy light to bomb constantly, it is estimated that after ten years of bombing, he can almost bomb out a city gate.

"Give it a try with these two drops of blood!"

Zhou Fool took out two transparent bottles, each with a drop of black blood in it. In fact, not only Ye Ren was thinking of a way, he was also thinking of a way, these two drops of demon blood were the most powerful blood they had refined so far, which was also what they found in this ruin, but it was a pity that they were blocked from the Black Castle, and they couldn't get more materials about the demon race at all.

"Ouch, my lord, if you don't take it out, I didn't think that this demon blood came from this secret realm, and this demon blood must be stronger than any demon blood we refined. Liu Lao slapped his forehead suddenly, and suddenly realized.

These two drops of demon blood have always been in the hands of Zhou Fool because they are too precious, so when they were preparing, they all forgot about it, and the demon blood they prepared was also some low-level demon blood.

Liu Lao trembled and took two drops of demon blood, and did not refine and transform them, he took them directly to the iron cabinet, and then opened one of the bottles, and a pure and uncomfortable aura enveloped everyone's hearts.

Buzzing!

When Elder Liu dripped this drop of demon blood into the magic cabinet, the entire magic cabinet suddenly buzzed like a volcano about to erupt, and those fragmentary parts were even more creaking, making people worry about a sudden collapse.

"This is also demon blood, why are these powerful!!" Sha Xin and Ye Ren felt very strongly because they were standing at the front, and the whole person seemed to be in the dark, this was only a drop of blood, and it was also extracted from the limbs of the dead demon by Zhou Fool, they couldn't imagine how powerful the owner of this blood was back then.

"That's why I have to explore this secret realm!" "Zhou Fool said seriously and enthusiastically, "Just because of the charm that these two drops of blood bring us, there must be more things waiting for us in this black castle." ”

"It seems that we still know too little about the demon clan!" Ye Ren squinted at the slightly vibrating city wall, this drop of blood seemed to prove Zhou's fool's persistence at this moment: "The city wall has moved." ”

"It seems that blood has done its job. ”

Fool Zhou looked at the city wall that was shaking and getting bigger and bigger, and said with a smile.

Boom, maybe the city wall felt the breath of the past, and the entire city wall actually slowly cracked, revealing a city gate, and then slowly stopped shaking again.

"Quick, everyone enter at full speed, leaving a team to guard!" Zhou Fool commanded in high spirits.
