It is a huge castle made of sand and gravel, and the castle gate is closed and cannot be opened.

The Blood Golem informed everyone that as long as they were able to successfully open the castle gate, they would be able to obtain the exclusive artifacts in the castle.

The way to open the castle gate is to continuously inject demonic energy into the city gate, and when the demonic energy in the city gate reaches a certain level, the city gate will be opened.

At this time, it is natural to need the help of these blood-colored stone people in Chu Nan.

After all, ordinary demons can't absorb demonic energy here, and can only obtain demonic qi through blood spirit crystals, if they use the demonic energy in the blood spirit crystals to inject into the city gate, this will greatly consume the demonic energy in the blood spirit crystals, and it is likely to directly consume the demonic energy in the blood spirit crystals.

Once there is no blood spirit crystal, its own strength will be greatly reduced, so it is naturally impossible for the blood puppet heavenly demon to inject demonic energy.

"Now you just have to inject demonic energy into it. ”

The Blood Golem Heavenly Demon gave orders.

Immediately, Chu Nan, these blood-colored stone people, walked to the gate of the castle one after another, put their hands on the city gate, and began to inject the demonic qi in their bodies into the city gate.

At the same time, they all found that even if they didn't deliberately inject the demonic qi in their bodies into the city gate, when their hands touched the city gate, the demonic qi in their bodies was surging into the city gate on their own.

It seems that this city gate itself has the ability to absorb demonic energy, and the absorption speed is still very fast, coupled with their deliberate injection of demonic energy, so that the city gate's absorption speed of demonic qi has reached the extreme.

In an instant, the demonic qi of these blood-colored stone men in Chu Nan was absorbed by the city gate.

"Rest first and get back to your breath. ”

The Blood Golem Heavenly Demon said.

The demonic qi of these blood-colored stone people in Chu Nan all originated from the blood puppet demon clothes, and now it is equivalent to injecting all the demonic qi in the blood puppet demon clothes into the city gate.

After the demonic energy is depleted, the blood golem demonic cloak will absorb the demonic qi on its own and replenish it.

Five or six hours later.

The demonic energy in the blood golem's cloak was already full, and everyone continued to begin to inject demonic qi into the city gate.

And so it went on for three days.

What Chu Nan and these blood-colored stone people do every day is to inject demonic qi into the city gate, and when the demonic qi is exhausted, they wait for the blood puppet demon clothes to absorb and replenish themselves.

It lasted for three days, and there was still no reaction from the city gates.

"If this continues, when will it be a head? ”

Some people have begun to complain in their hearts, thinking that it is boring to inject demonic energy into the city gate every day, which is very boring, but they dare not express their dissatisfaction in front of the blood puppet heavenly demon, let alone be lazy.

The Blood Golem Heavenly Demon attaches great importance to the opening of the city gate, staring at them every day, and no one dares to be lazy at all.

Another three days passed.

It's business as usual.

During this period, someone asked the Blood Golem Heavenly Demon how much demonic energy needed to be injected into the city gate before it could be opened.

The Blood Golem Heavenly Demon told everyone that the city gate would not open until it reached at least the amount of demonic energy in the March realm.

"March Realm!"

It was then that everyone realized the enormity of the project.

In the Heavenly Wolf Birth Land, when they break through the Primordial Spirit Realm, they will condense one round of Blood Moon, and powerhouses like the Blood Golem Heavenly Demon can now condense two rounds of Blood Moon!

The more Blood Moon you can condense, the stronger your strength will be.

The March realm is the degree to which the three rounds of blood moons are condensed.

Chu Nan and the others could only inject the demonic qi of the late stage of the primordial spirit realm every time, and it would take at least a month to reach the amount of demonic qi in the March realm through continuous accumulation.

Chu Nan was secretly glad that the time flow speed of this Heavenly Wolf Birth Land was different from the outside world, otherwise the time consumed here would be too long.

At the same time, after Chu Nan realized that the city gate could not be opened in a short time, he had already begun to wonder in his heart, whether to find something else to do every day, otherwise it would just inject demonic energy into the city gate every day, which would be too boring and boring, and it would be a waste of time.

"Maybe I can try to specialize in these demonic ......"

Under the inheritance of the Demon Emperor, Chu Nan's understanding of demonic qi is not weaker than that of ordinary demons, and even deeper than that of ordinary demons.

Now is the right time to use this blood puppet cloak to conduct research.

That day.

Chu Nan began to use the time for the blood puppet demon cloak to recover his demonic qi and quietly researched it.

Time passes.

Twenty days passed in the blink of an eye.

In the past twenty days, Chu Nan and these blood-colored stone people have been injecting demonic energy into the city gate every day, and some demons happened to come here during this period.

They were very unlucky, and they were directly forced by the Blood Puppet Heavenly Demon to put on the Blood Puppet Demon Costume and join the ranks of Chu Nan and the others.

Now, with the infusion of demonic energy by everyone day and night, the opening of the city gate is just around the corner.

It was also at this time that Chu Nan finally made progress in the study of demonic qi.

Through the demonic energy in the blood puppet demon cloak, he successfully comprehended a secret technique in the Demon Emperor's inheritance.

Originally, with his talent, it didn't take so long......

The reason why it took so long to successfully study and comprehend was mainly because Chu Nan had not been able to completely devote himself to it and entered a state of selflessness.

While he was studying and comprehending, he also had to pay attention to his surroundings, fearing that something unexpected would happen, and every once in a while, no matter where he was in his research, he had to stop first and inject demonic energy into the city gate before he could continue his research.

In many cases, it was interrupted at a critical moment, which seriously affected the speed of research, and it took 20 days in a row to successfully comprehend the research.

Although it took a little more time, but now that he has completed his research and comprehension, Chu Nan has also successfully mastered this secret technique, which can't help but give birth to an idea in Chu Nan's heart.

"I wonder if this secret technique I have comprehended is effective against the demonic qi in this Heavenly Wolf Birthplace?"

Chu Nan's heart was pounding, and he was looking forward to it, so he decided to try it quietly.

Call!

Immediately.

He used his demonic energy to quietly perform a secret technique, and before and after coming to the city gate, Chu Nan put his hand on the city gate, and in his palm, the pattern of the secret technique had been condensed.

Airplanes!

Suddenly, Chu Nan felt the demonic qi flowing into the city gate in his body, and he was stunned, and then directly stopped flowing.

"It works!"

Chu Nan was overjoyed in his heart.

At the same time, when Chu Nan's secret art pattern touched the city gate, the demonic qi in the city gate was actually rejected by the secret art pattern and began to flow out of the city gate.

Chu Nan's eyes flashed, and a bold idea suddenly grew in his heart!

Without hesitation, Chu Nan immediately used the secret art pattern to control the direction of rejection, so that the demonic qi in the city gate would be ...... after being repulsed Along Chu Nan's palm, it flowed into Chu Nan's body!

The effect of this arcane pattern lies in its ability to repel demonic energy to a certain extent......

At this time, under the rejection of this secret art pattern, the demonic qi in the city gate rushed down Chu Nan's palm and poured into Chu Nan's body.

Chu Nan was overjoyed in his heart, but he didn't dare to show the slightest on his face.

He knew that once the Blood Golem Heavenly Demon discovered his actions, he would definitely kill himself without hesitation.

"Developed!"

"It's developed now!"

Chu Nan's excited heart was pounding.

While others were constantly injecting demonic energy into the city gates, he was constantly absorbing demonic energy from the city gates.

And now, the demonic qi in the city gate, under the continuous injection of everyone these days, has become extremely numerous, and it is about to reach the condition of opening the city gate......

At this time, he was affected by Chu Nan's secret art pattern, and the demonic qi began to drain from the city gate, and it flowed directly into his body under Chu Nan's control.

"If I can absorb all the demonic energy in this gate, then I ...... here It will be very likely to reach the March realm directly!"

Chu Nan's heart was beating fast.

He knew very well that this would be an opportunity for him to rise in this wolf world!

Originally, Chu Nan had been worried because he didn't have the opportunity to improve his strength in this Heavenly Wolf Birth, but now he finally ushered in an opportunity.

Although he was excited in his heart, Chu Nan was not carried away by joy, and he didn't put his hand on it all the time because he could absorb the demonic energy in the city gate, and absorbed it vigorously.

Just like the time when he went to the city gate to inject demonic energy, when the time was up, Chu Nan withdrew his palm and did not absorb it too much, and the whole person was quite cautious.

He is well aware that the more this situation is, the more cautious it is to be.

Because sooner or later, the Blood Golem Heavenly Demon will find out about the problem.

At this time, once you get carried away with the excitement, it is likely that some problems will be noticed, and you may not see anything at this time, but after the investigation, it will be difficult to escape suspicion.

Meanwhile.

These demonic qi that was inhaled into Chu Nan's body, in the process of flowing into Chu Nan's body, did not pass through the Scarlet Stone Man, Chu Nan knew his current situation, as if he was imprisoned in the body of the Scarlet Stone Man, although he could control the Scarlet Stone Man, but the Blood Golem Heavenly Demon only held the first control of the Scarlet Stone Man.

Moreover, Chu Nan didn't know if the Blood Puppet Heavenly Demon had left any special marks or inductions on this Scarlet Stone Man, so he didn't dare to let these demonic qi pass through the Scarlet Stone Man.

These demonic qi absorbed by Chu Nan flowed directly into Chu Nan's body through the pattern of secret arts, and then was refined into blood spirit crystals by Chu Nan.

The Blood Golem Heavenly Demon didn't find anything abnormal.

After all, from the naked eye alone, this city gate could not tell how much demonic qi had been stored inside, and the blood puppet heavenly demon could only be inferred by time.

"It's coming!"

"The gates are about to open!"

The Blood Golem Heavenly Demon's eyes were blazing, and he was looking forward to the opening of the city gate.

He didn't know that from this day on, the demonic energy in the city gate was constantly draining.

Every day, Chu Nan pretended to inject demonic qi, but in fact, he was absorbing the demonic qi in the city gate, and even Chu Nan increased the absorption speed, condensing two secret art patterns in his palm at one time, so that the rejection of the demonic qi in the city gate increased, and a large amount of it poured into Chu Nan's body.

Chu Nan knew that he had to hurry up, and in a few days, the Blood Puppet Heavenly Demon would find out the problem when he saw that the city gate was not opened.

Everything was the same as Chu Nan guessed.

Six days later.

The Blood Golem Heavenly Demon looked at the city gate expectantly, waiting for the city gate to open.

According to his calculations, the gates will be opened today.

However, he waited for a long time, and there was no movement at the city gate.

"What's going on?"

The Blood Golem Heavenly Demon frowned, feeling that something was wrong, according to his calculations, the city gate would definitely be opened today, but now there was no reaction.

"Someone is lazy!"

"Someone must be lazy!"

The Blood Golem Heavenly Demon's eyes flashed with evil energy, closed his eyes, and directly began to check the flow of demonic qi in the various Scarlet Stone People these days.

He is the creator of the Blood Golem Demon Suit, and he can understand the flow of demonic qi of all the Scarlet Stone People through the Blood Golem Demon Cloak at any time, and according to the flow of the demonic qi of each Scarlet Stone Man, he can judge whether someone is lazy.

For a moment, everyone felt that they had lost control of the Scarlet Stone Man.

Chu Nan had expected this, and even in order to avoid revealing his feet, Chu Nan was absorbing demonic qi these days, and at the same time injecting demonic qi into the city gate as usual.

After all, the demonic qi injected was the blood puppet demon cloak, not the demonic qi absorbed by Chu Nan and re-injected into it, and there was no loss to Chu Nan.

Therefore, even under the investigation of the Blood Puppet Heavenly Demon, no problems were found from Chu Nan, Chu Nan's daily demonic qi flow was the same as others, there was no problem, but there were a few people, the demonic qi flow was slow, and they were suspected of being lazy.

But even if these people are lazy, the demonic energy in the city gate should be enough, but now the city gate is not opened.

"Am I wrong?"

After thinking about it for a while, the Blood Puppet Heavenly Demon didn't find a reason, so he could only let Chu Nan and these blood-colored stone people continue to inject demonic qi into the city gate.

Two more days passed.

There was still no movement at the gates.

The Blood Golem's brow furrowed even deeper.

Even when everyone injected demonic energy, he personally checked and strictly checked everyone, but he still didn't find the reason.

"The problem shouldn't be with these people. ”

The Blood Golem felt that there might be some changes at the city gate that he didn't know about.

"Keep infusing the demonic energy. ”

The Blood Golem Heavenly Demon was a little irritable.

......

Five days later.

The city gate was still not opened, and the face of the Blood Puppet Heavenly Demon was quite ugly, and the whole person was going crazy.

He'd spent so much time here, and the gates never opened.

"What the hell went wrong!"

The Blood Golem Heavenly Demon thinks about it every day.

And many blood-colored stone people also felt tortured, after all, for a month, they were boring to inject demonic energy every day, and they couldn't do anything......

Thinking that the city gate was about to be opened, they were about to say goodbye to such a day, but they found that the city gate had not moved so far, and they couldn't help but start to doubt the words of the blood puppet heavenly demon in their hearts, and felt that the opening conditions of the city gate were definitely more than the demonic energy of the March realm.

Chu Nan is beautiful here.

With the continuous absorption of demonic qi, although Chu Nan didn't know how much demonic qi was left in the city gate, the blood spirit crystals here in Chu Nan were already extremely numerous.

Meanwhile.

Not far away, the woman who had been hiding here, waiting for the Blood Puppet Heavenly Demon to open the city gate, finally couldn't stand it anymore at this moment.

"What a piece of rubbish, you can't even open a city gate!"

She originally thought that after the Blood Puppet Heavenly Demon opened the city gate, she would kill it and directly snatch the exclusive artifacts in the city gate, but she didn't expect that after waiting here for so many days, the city gate showed no sign of opening at all.

She couldn't wait any longer, so she decided to attack and open the gates herself.
