Just when Xiao Qi was at a loss for what to do with the iron gate, at the entrance of the dark passage, there was another violent slam sound, this time the sound was not like hitting the cold iron gate, but impacting the location of the machine. Feeling the gravity of the machine, Xiao Qi's heart also rose to his throat again.

I can't sit still, Xiao Qi's mind moved, so he returned to Lao Jun with the iron thorn, and thrust the spike in his hand into the machine.

With a sharp and piercing creaking, the internal machine completely broke, followed by a dull sound of gold and iron falling to the ground. There was no more sound in the tunnels.

Xiao Qi let go of his hands at this time, and at this time, his legs were already trembling like sifting chaff, and he could no longer stand firmly, so he fell to the ground, snuggled against the wall and gasped.

Xiao Qi can't judge whether the camel is alive or dead, but at least he can buy him more time. Xiao Qi took a few breaths, then got up again, his eyes swept over the strange object on the opposite wall. He didn't know what they were, but some of them had strong blades, so he brought a stone pier, climbed up, and plucked one of the ring blades.

When Xiao Qi held the handle of the knife, which was like a ring, he trembled like chaff, and he felt as if a suction force was spraying out along the palm of his hand, and then all the strength of his body surged towards the hilt.

Xiao Qi's whole body was tense, and the demon patterns were also condensed at his elbows, he tried to use the magic power to compete with the suction of the knife handle, but the next moment the magic power was also sucked away, until Xiao Qi was weak and could no longer exert a little strength, the ring blade fell off from his palm as if he was full, and plunged into the ground with a clatter.

Xiao Qi stared at the handle of the ring knife with weak eyes, not knowing what kind of spiritual weapon this was, and why it would suck away all his strength. However, Xiao Qi was still full of confidence in it, and felt that this ring blade was very powerful, and if it could be stimulated, it might be able to shatter the thousand-year-old cold iron.

Thinking of this, Xiao Qi stepped forward again despite his exhaustion, wanting to reach out and pull it out from the ground. However, no matter how hard he tried, he couldn't pull it out in the slightest.

The blade didn't move as if it had taken root in the ground.

Xiao Qi had no choice but to let go of his palm, no longer paying attention to it, and turned his gaze to another object, it was not the same, but a string, there were more than a dozen kinds of sharp or flat blades in series. It looks like a necklace with a strange shape.

When Xiao Qi plucked it from the wall, he clearly felt a chill in his little palm, it was only a little at first, and as his ten fingers became stiff, his palms and elbows were numb. This feeling, Xiao Qi is extremely familiar, it is the breath of the thousand-year-old cold iron.

Xiao Qi stared at these blades made of thousand-year-old cold iron, wondering if they could also cut the thousand-year-old cold iron. So he returned to the west corner of the hall with this string of blades, and facing the shriveled and black face of Traceless, Xiao Qi solemnly assured him: "Brother Traceless, I will not leave you no matter what, I will take you out of here with me."

The zombie's cheeks didn't respond as before, but there seemed to be a glimmer of gold in the eye sockets of the two holes. But it soon disappeared.

Xiao Qi's eyes stared aggressively at the trapped lock iron gate, and with a fierce force, he condensed the demon pattern of his whole body in his right arm, and then slashed a sharp blade towards the thousand-year-old cold iron. The blade slashed through the thick iron surface, and suddenly burst out countless sparks, and when Xiao Qi used up all the condensed magic power, he raised his hand and stared at the surface of the dark black iron gate. In an instant, a sense of powerlessness came to his heart again, and he still failed.

The iron gate has not been broken, the blade has not been blunted, and neither of them can hurt each other.

Xiao Qi tried a few other blades one by one, and the ending was still the same.

At this time, Xiao Qi also lowered his head, almost did not dare to face the shriveled face without a trace, he didn't want to leave his brother alone, but now facing this thousand-year-old cold iron gate, he also tried his best.

Suddenly! Xiao Qi's eyes lit up, and he seemed to remember something along the iron shackles that were only half left. So he raised his head suddenly, stared at Traceless and said excitedly: "Traceless, I will definitely be able to save you out!"

The next moment, Xiao Qi ran back to Lao Jun with longing, staring at the red in the fire gathering array under his feet. He seemed to be looking for something, and when his eyes fell to a corner and found the cold iron chain in a state of melting, he finally couldn't suppress his inner emotions and laughed heartily.

Soon, the laughter stopped abruptly, Xiao Qi's eyes wandered between the thousand-year-old cold iron cage and the fire gathering array, and an inexplicable sense of frustration welled up in his heart. In his sight, the interval of less than thirty paces was like an impassable moat, which made them only one step away from freedom, but the end of the world.

Why don't you set up a fire gathering array yourself!

Just when Xiao Qi hesitated, the cold voice of the old demon in Zhihai reappeared.

Rearrange the Gathering Array?

Hearing this, Xiao Qi's eyes once again focused on the gathering fire array that was crocheted with a quadrangular array, and suddenly felt that the old demon's proposal was so ridiculous. Such an ingenious array layout, let alone a relayout, even if he imitated and depicted a silhouette, it would be impossible to do it.

Don't you think that every time you lay out a fire-gathering array, you have to re-draw the quadrangle diagram? If so, it will take at least ten years to lay out a fire-gathering array, and if you have that time to waste on this, no one else will.

Who knew that as soon as Xiao Qi's thoughts were formed, he was refuted by the old devil and had no skin.

This quadrangular array is a formation plate, also known as the array mother, which can be recycled and reused, this thing is not a rare thing in the cultivation world, but it can only be built by big families, and more people can use the array mother to lay out the formation.

Speaking of this, the old demon also passed a mantra to Xiao Qi's consciousness, this is the closing formula, with it, you can recycle and use the array mother, it's just a fire crystal, and you still need to lay it out yourself.

Xiao Qi slowly opened his eyes, at this time he was already familiar with the closing technique, and then he stretched out his hands and played some tricks towards the square array under his feet. After that, a clear striped disc was revealed, which was ingested from the ground little by little, and finally turned into a jade talisman. It is densely engraved with inscriptions, like oracle bone shells.

When Xiao Qi reached out and grabbed the array mother jade talisman, dozens of fire crystals landed on the ground, they were still glowing with a trace of red light, but the heat could no longer be leaked.

Xiao Qi walked back to the iron cage with the array mother, took a solemn breath, crossed his hands, pressed the jade talisman in his palm, and divided it hard, and suddenly a series of stripes sprayed down from his palm, and in less than a quarter of an hour, it was rebuilt into a square array under his feet. It's just that this time the Quartet Clan and the Gathering Fire Array were surprised, and it could even be said that they were completely two formations.

Just when Xiao Qi was puzzled, the old demon explained again in a cold tone, there are at least hundreds of formation diagrams on this quadrangle array, and the fire gathering array is just one of them, as long as you remember the position where the flame stone is just now, you can use your memory to re-copy a fire gathering array with the flame stone.

Xiao Qi was dumbfounded, he was just describing the closing method just now, and he didn't carefully remember the arrangement of the flame stone at all. Just when Xiao Qi was in an embarrassment again, his eyes touched the seven-star flame totem behind the Laojun furnace. Its star position happens to meet the layout of some formations in the quadripartite diagram. Xiao Qi didn't know if this was the Gathering Fire Array, and he could only get one at this time, so he placed the seven flame stones on the Seven Star Array.

As the flame stones flashed red one by one, the ground, which was originally gray, suddenly turned red. I saw that the fiery red lines wandered around, and a series of formations were formed, among which there was also a faint ancient fire beast jumping here.
