The group continued to walk forward, and Zong Zheng also followed their footsteps, passing through the long corridor full of flames, Zong Zheng couldn't help but glance back at the Heavenly Sword, looking at the giant sword, his mind could always come to mind the sword in the carved painting on the top of the wall.

The guards who cleaned up the mess did not carry Miao Ji away, the heat of the Zhutian Sword on his body was too strong, and those guards couldn't get close at all, so Miao Ji was coldly abandoned on the ground and roasted by the Zhutian Sword.

This promenade is far deeper than expected, and its layout is like a thousand plates of incense, circling one circle after another, although it is not far from this core area, but it has no diameter.

The more you walk into the corridor, the closer you get to the core area of the Golden Temple, the more cold everyone feels, this cold is far more uncomfortable than the biting cold, every step forward, the cold force is obviously aggravated, gradually, those low-skilled guards gradually can't resist, their hair and beard are gradually covered with white ice slag, until their legs are numb and unconscious, collapsed to the ground, can no longer move forward, Kublai Khan also suddenly stopped.

"Great Khan, the guards can't bear the cold, look ahead, there is still a long way to go, this cold will be deeply aggravated every step forward, with the strength of me and the Great Khan, I'm afraid that if you can't get there, you will have to freeze, so it's better to retreat and defend the entrance of the cave." Seeing the situation in front of him, Fasipa whispered to Kublai Khan and gave him a look.

Kublai Khan also felt this bone-chilling cold, his skills were far inferior to Tianjizi, Zonglun and Zongzheng, he looked forward, and knew that what Fa Sipa said was reasonable, but it was a pity that he couldn't spy on this eternal top secret with his own eyes, it was a pity, and he hesitated for a while.

"Oh no, no!" A guard rushed in from outside, with a heavy chill on his body, because he was in too much hurry, he ran too fast, he didn't have time to pay attention to the sudden cold of his body, and when he ran in front of Kublai Khan, he suddenly stopped, and soon he couldn't even breathe.

"What's going on?" Kublai Khan asked, and after asking, he also clearly felt that he had difficulty breathing!

Zong Zheng poured a trace of true qi at the guard, and the guard gradually breathed smoothly and said: "The outside of the Golden Palace is starting to freeze, and in a few moments, the entrance will be frozen, and it won't take long for the entire Golden Palace to become a snow-capped mountain again, please evacuate quickly." ”

After Kublai Khan listened to what the guards said, he quickly dispelled his original hesitation, even if there were thousands of unwillingness in his heart, he could only withdraw from the Golden Palace and make plans again, and instead evacuated with Fa Sipa and the collapsed guards.

"This cold air is from the inside out, it seems that there is an extremely cold thing hidden in the Golden Palace, and Xuefeng Mountain will soon become a snowy mountain again, what should I do?" Zong Zheng was in a dilemma, but he only thought for a moment before he was determined to move on.

Because he knows that there is only one chance, and he finally came in, if he goes out this time, he will never have the opportunity to find the answer in his heart, and in the end he will only die, but what is there to fear from death now! It is better to move forward, and he has come with the last ray of hope, at least not with the deepest regret.

And Zong Lun and Tianjizi naturally want to move forward, their lives are for the last secret, this is their fate, more than ten generations of perseverance and struggle, what they are waiting for is nothing more than such an end, they are extremely determined, without half a moment's hesitation.

Kublai Khan thought that Zongzheng, Tianjizi, and Zongzheng would retreat in the face of difficulties, so he followed himself and retreated, and when he looked back after a few steps, he found that the three of them had continued to move forward.

"Zongzheng, aren't you afraid of losing your life? When the snow covers the mountain, you will never be able to get out!" Kublai Khan shouted to Zongzheng, not knowing what kind of state of mind he had, and his tone was not only curious about Zongzheng knowing that it was a dead end but still resolutely moving forward, but also obviously reluctant to let Zongzheng die.

"I'm afraid, but I want to get an answer more!" Zong Zheng replied in a dashing manner, and continued to move forward.

When Kublai Khan heard Zongzheng's answer, he only thought that Zongzheng was going for the secret in the Golden Palace, but he didn't know that the answer he wanted was not so.

"Let them go! Kublai Khan looked at the figures of the three people, and slowly withdrew from the corridor, and a large number of people holding torches to meet Kublai Khan were stationed at the entrance of the cave, and when Kublai Khan and Fasipa walked out of the entrance, the guards withdrew from the entrance with torches.

Without the warmth of the torches, the entrance to the Golden Temple was quickly permeated by the cold air inside and out, and the entire entrance was covered with a thin layer of ice until it became thicker and thicker.

This golden palace is originally an ice cellar, the spiritual fire at the entrance blocked the leakage of the cold inside, and now the spiritual fire is discharged due to the forging of the Heavenly Sword, and this cold air is unhindered on this passage, but the cold air is blocked by another thing, that is the Heavenly Sword.

All of this is an arrangement in the dark, and the Zhutian Sword can only gradually cool down under such a cold air, this passage is at least because the Zhutian Sword temporarily resists the cold from the inside, and it is only that the outermost entrance of the passage is blocked by ice and snow, and the depth of the ice and snow seal also stops near the Zhutian Sword, once the Zhutian Sword is cooled and cannot resist the cold, this passage will be completely sealed from the outside in, and now that it has lost the protection of the spiritual fire, this ice will spread inward.

Zongzheng and the others are undoubtedly playing a game with time, they must withdraw before the Zhutian Sword cools down, otherwise once this passage is blocked by the cold ice, they will freeze their eternal life in the Golden Palace.

Kublai Khan withdrew from the Golden Palace and came to the right side peak under the escort of the guards, and he looked at the opposite Golden Temple and the ice and snow again, and sighed gloomily, his face full of pity.

"The Great Khan doesn't have to be depressed, as long as there is Zongzheng, there is still hope for everything, don't forget, he is the son of dragon scales, everything is providential. Fasipa saw Kublai Khan's thoughts and comforted.

Kublai Khan corrected his train of thought, and he quickly reacted, "Come on, withdraw most of the soldiers and horses from Xuefeng Mountain, and concentrate all the trebuchets on the left peak, as well as the tung oil that has not been used up, here." ”

"Great Khan, this is?" Fa Sipa suddenly did not understand Kublai Khan's intentions.

"National Teacher, Ben Khan asks you, how long do you think such a cold iceberg can last with their skills?" Kublai Khan asked.

"Half an hour at most," Fa Siba replied.

"Okay, herald, after half an hour, gather all the tung oil and trebuchets and aim at the entrance of the cave. Kublai Khan ordered, and after a moment of thought, he finally understood Kublai Khan's intentions.

"Zongzheng, Ben Khan can only help you get here, good luck! I hope you can come out safely, don't let Ben Khan down. Kublai Khan looked at the majestic snow-capped mountains in front of him, and said in his heart,

Whether it is based on the purpose of wanting to know the ultimate secret or his personal appreciation of Zongzheng, his feelings are sincere, at least he hopes that Zongzheng can come out alive with the secret.

Zong Zheng, Zong Lun and Tianjizi have the whole internal force to protect the body against the increasingly heavy cold, they followed along the corridor, and came to the core of the top floor of the entire Golden Palace, they all know very well that once the outside of the Golden Palace is covered by snow and ice, the cold inside will be heavier, not only that, without external oxygen input, the air here will soon be thinner, even if they don't freeze to death, they will die of lack of oxygen.

Since Miaoji was jointly plotted, Tianjizi and Zong Lun were each a little vigilant, before the final secret was solved, Zong Zheng was safe, so only Zong Zheng walked in front, Tianjizi and Zong Lun followed Zong Zheng side by side.

Time passed minute by minute, and the golden hall outside was gradually covered with a layer of ice and snow, and the faint golden yellow in the ice and snow could still be seen, and the entire golden temple disappeared from sight in less than a moment, and the ice and snow were still thickening.

The troops of the main peak were basically withdrawn, and Kublai Khan and Fa Sipa stood on the side peak wrapped in gray mink wool and quietly watched the scene in front of them.

This time a big project was used, which was extremely draining of manpower, material and financial resources, if it was in vain, it would naturally cause opposition from the ministers of the clan, which was nothing, he didn't want to miss this last secret, he didn't want to leave a lifetime of regrets, if Zongzheng couldn't get out of the whole body, he really couldn't think of anyone else in today's world who could crack the last mystery.

Therefore, when Kublai Khan looked at the snow-capped mountains in front of him, he was preoccupied and could not be relaxed.

The three of Zongzheng circled around, attracting internal force and true qi to keep out the cold, and they were about to come to the core of the Golden Palace, but they were stopped by an ice-blue ice door.

This ice gate is the only place to pass inside, and its cold power is extraordinary, and the three of them are only three feet away, and they already know that this is the source of the cold power of the entire Snow Peak Mountain.

For this secret, the three have cut off the way to retreat, naturally unwilling to retreat for the little Xiaoice gate, but the three of them tacitly agreed, temporarily put down each other's defenses, and jointly introduced internal forces to hit the ice gate together.

With a bang, it only left a shallow hole in the ice door.

The three of them looked at the painless hole in front of them, and immediately had a bad feeling, this ice layer was far more difficult to break than the three imagined, although the internal force of the three of them decreased under the cold force, but it was powerful enough, but in the face of such an ice door, only the shallow hole was left.

The three of them once again worked together to aim at the hole and deepened their skills by a few more layers, however, they only went a little deeper than the hole.

Through the hole, they could feel that the ice door was much thicker than they had imagined.

The three of them were dumbfounded, this time it took six or seven successes, looking at the situation in front of them, even if the three of them tried their best to hit the ice gate thousands of times in a row, I am afraid that it would be in vain.

Tianjizi stepped forward, only gathered true qi and injected it into the concave hole, and he had already felt a great cold force, and quickly withdrew his palm, and exclaimed:

"It's not a simple door, it's a whole block of ice that's so thick inside. ”

When I entered this mysterious place with great anticipation, I found that there was only a huge piece of ice blue here.

"Could it be that there is something hidden in this giant blue ice?" Zong Zheng thought of this question for the first time, he had never seen this kind of ice before, it was as pure as the sky, as blue as the sea.

Zong Zheng leaned over to pick up the shattered ice crystals on the ground, and in an instant, the cold air penetrated into his bones, forcing him to immediately and sensitively throw the ice crystals to the ground again.
