In the stone room, Chu Jingtian was dragging the Shuanglong Ding with one hand, and the other hand was throwing a medicinal herb into the Ding.

And on the workbench in front of him, there were some medicinal essences that had been refined.

Today was the entire month he had entered this stone chamber, and it was also the fifth day that he had begun his alchemy.

It took him twenty-five days to read through all the relevant alchemy materials in the black ring. Although he may not be able to understand it all, it will be of great help to him in refining the Iron Bone Pill in the next step.

Of course, if you want to refine the Iron Bone Pill, it is not achieved overnight.

Although there is only one level difference between the human-level mid-level pills and the human-level low-level pills, the difficulty of refining these two levels of pills is not as simple as one and two, but there is a gradual improvement process.

Therefore, if Chu Jingtian wanted to refine the human-level mid-level Iron Bone Pill, he had to first refine some less difficult pills to practice his hands.

For example, the Detoxification Pill he was refining now was an elixir with a difficulty between the intermediate and primary levels of the human rank.

Moreover, he had been refining this elixir for five whole days, but he had not succeeded in doing so once.

"Bang"

A sudden explosion made De Chu's hands tremble, and the medicinal materials in the medicine tripod instantly turned into ashes. Then, he looked at the bronze door of the stone chamber with some helplessness.

The loud noise came from this gate.

"Bang":

Just as he looked at the door, another bang rang out.

"Can't you wait" muttered to himself softly, Chu Jingtian's face showed a faint smile, and then he continued to bury his head in alchemy, not worrying that those people would rush in at all.

First, this bronze gate was left by the master of the Heavenly Fire Palace, and it was definitely not so easy to break, and second, he wished that these people would rush in now, so that he would not have to do alchemy.

And just as Chu Jingtian expected, outside the stone room, Pang Hong and the four of them really couldn't wait.

After a whole month of waiting, it had exhausted their patience.

"Damn, that bastard isn't going to come out. Liao Qian said angrily.

"Don't worry, let's just attack the gate like this, the loud noise in the stone room is much louder than outside, he can't stand it for long. Mu Hai's words were full of confidence.

Their purpose in attacking this gate was not to break the gate at all, because they knew very well that with their strength, they might not be able to break the gate.

Therefore, their purpose is to constantly harass Chu Jingtian, so that he can be overwhelmed and run out by himself.

"Hmph, if you had done this earlier, that guy would have come out of it long ago. Hearing Mu Hai's words, Pang Hong said angrily.

With his arrogance, he has been hiding here for more than a month, and he has long been angry, and now his anger has exploded even more by taking this opportunity.

Mu Hai frowned slightly, glanced at Pang Hong with some displeasure, and said: "I didn't stop you, if you think of any way, you can naturally use it, but if there is no good way, then it's best to shut up, so as not to annoy people." ”

"You" Pang Hong was angry, but he couldn't speak, he really didn't have anything better.

"Okay, let's calm down, and don't forget, our goal is still there. Whatever you do, it's all that counts to get that bastard out. Liao Qian stood up and stopped the two who were going to quarrel.

Immediately, both of them also fell silent, and then continued to let people attack Shimen.

But what they didn't know was that after hearing the continuous sound of slamming the door, Chu Jingtian in the stone room simply flashed back to the Heavenly Jealousy Tower.

In this way, letting him make noise outside will have no effect on him.

And at the moment of entering the Heavenly Jealousy Tower, Chu Jingtian's expression was slightly stunned, and with a smile behind him, he sat directly cross-legged.

In the space of a month, the true qi in his dantian overflowed again, and now he was about to complete his ninth true qi compression.

Ordinary martial artists, after completing this compression, the true qi will begin to liquefy, and then enter the condensation realm, but Chu Jingtian will enter the tenth level of the true qi realm that others do not have, and if he wants to enter the condensation realm, he must complete the tenth compression.

After more than eight hours, Chu Jingtian completed the compression, and then jumped out of the sea of spiritual energy directly and continued to study alchemy.

For him now, unless he is advancing to the Condensation Realm, this kind of promotion can't make him too excited.

Time passed slowly in this roar, and in the blink of an eye, it was another month. It has been three full months since Chu Jingtian came to this Heavenly Fire Palace.

After a month of continuous study and exploration, his alchemy level was already able to start refining the Iron Bone Pill, but according to his judgment, it would take at least a month for him to successfully refine this pill.

Because this Iron Bone Pill is definitely the most difficult one among the human-level intermediate pills, there are more than 30 kinds of herbs involved in it, and the treatment of each medicinal material is different, when refining, the slightest mistake will lead to the failure of alchemy.

It is no exaggeration to say that if you want to successfully refine this kind of elixir, it is definitely an extremely severe test for the alchemist's alchemy skills. If Chu Jingtian could successfully refine the Iron Bone Pill, then in the future, the human-level mid-level pill would not be a problem for him at all.

Fortunately, in the gray storage ring, the master of the Heavenly Fire Palace had prepared enough materials for Chu Jingtian to use, and he didn't have to worry about the materials.

Therefore, in order to successfully refine and leave here as soon as possible, Chu Jingtian was almost sleepless in alchemy.

In the hall on the first floor of the palace, Pang Hong, Niu Jie, Mu Hai, and Liao Qian sat opposite each other.

"We've been waiting here for two months, and the gate has been banging for a month, but the people inside haven't reacted at all, should we think of another way" Niu Jie looked at the other three and asked.

"It's useless to smash the door to interfere, we can't open the door, it seems that there is nothing we can do. Liao Qian also said helplessly.

"Now is the time to test patience. Mu Hai said lightly, "It's been more than two months, his food should be almost consumed, let's just wait until he runs out of food, he will definitely come out." ”

"Hmph, do you know how much food other people have, in case that person's food is enough for a year, we will just keep consuming it," Pang Hong said disdainfully.

As for Pang Hong's ridicule, Mu Hai just smiled faintly, "Anyway, I'll wait here, if you want to leave, I won't stop you." ”

Pang Hong's expression was stunned, and he was speechless.

And Niu Jie and Liao Qian were also full of helplessness.

They have wasted more than three months of time for the sake of things here, and if they leave now, they will naturally be unwilling.

But if they are not willing to leave, then they have no other way but to wait. And they all know that this will be a wait that doesn't know when it will end.

"So, wait patiently, it's been more than two months, and I'm sure his food won't last long. Muhai said.

In fact, he originally wished that the remaining people would leave quickly, but he was a little worried about the strength of the person in the stone room.

So to be on the safe side, he still hopes that these people will stay.

Hearing this, the other three also calmed down.

It's just that no one knows that Pang Hong's angry words really hit the point, and Chu Jingtian's food can last far longer than a year.

However, the sound of the bombardment of the gate was still ringing.

People will become irritable in the long-term noise environment, and they still hope that Chu Jingtian can't bear it and rush out by himself.

In the Heavenly Jealousy Tower, Chu Jingtian, who was refining the pill, shook his body violently, with an irrepressible look of excitement in his eyes, and then quickly sat cross-legged.

After this month's time, the true qi in his dantian once again overflowed outward.

Not daring to slack off, Chu Jingtian immediately mobilized his spiritual power and the true qi in the meridians to suppress it in the dantian.

This time the compression of true qi was extremely crucial for him, because after this time, his true qi would begin to liquefy, and his strength would also step into the condensation realm.

However, this compression will definitely be the hardest.

After the first nine compressions, the true qi in his dantian had already reached a certain concentration, and now compressing it was like stuffing sand into a bucket full of sand, and the difficulty could be imagined.

"Bang"

A dull sound came out violently from Chu Jingtian's body, and his suppressed spiritual power and true qi collided with the true qi overflowing from the dantian.

The intense pain made Chu Jingtian's brows furrow violently, if he hadn't experienced two qualitative changes in the body of the acupuncture point refinement, his body would have become extremely strong, just this collision was enough to make his abdomen explode.

Enduring the severe pain, Chu Jingtian mobilized his spiritual power and squeezed the overflowing true qi towards the dantian.

But then, he showed a wry smile, this time the difficulty of compression is much more difficult than the ninth time.

He felt that his spiritual power was completely acting on a wall, and no matter how much he squeezed or pushed, those overflowing true qi would not move at all.

He knew that this was because the dantian was already filled with true qi, but even so, he had to complete the compression, otherwise once these true qi rebounded and went violent, he would be seriously injured if he didn't say it.

As soon as his heart moved, Chu Jingtian's hand flipped over, and a Qi Returning Pill was swallowed into his abdomen.

According to common sense, the true qi recovered from this Qi Pill should have flowed into the dantian, but at this time, his dantian had already been stuffed, and the true qi formed by those pills was also blocked in the meridians.

In this way, invisibly, the power that Chu Jingtian used to compress the true qi was strengthened by another point. It's just that the tenacity of those overflowing true qi has been accomplished beyond his expectations, and his suppression still has no effect.

With a grit of his teeth, Chu Jingtian took out another Qi Pill and swallowed it~ Good search basket color, you can read the following chapters as soon as possible
