After Zhang Yi and Wang Yunfeng returned to the ice room along the ice path again, Nie Qingchen and Master Guangzang Fahong had indeed woken up, and the two of them were moving their muscles and bones at this moment.

Seeing the two of them coming back, Nie Qingchen obviously knew what they were going to, and immediately asked, "Have you gone to see that abyss?" ”

Zhang Yi nodded: "I didn't expect that in addition to such an ice cave at the bottom of this heavenly pool, there is also such a terrifying abyss. ”

"The abyss is indeed terrifying, and I have been there many times to try to find its depth, but unfortunately I have never succeeded, and perhaps only with modern survey tools can I find its depth." Nie Qingchen nodded: "But that ice channel entrance is a good practice ground, and it is there that my Heaven Slashing Crazy Sword Technique has been comprehended for several years before it has its current power." ”

Master Guangzang Fahong was still so displeased with words, and said slowly: "Let's take our swords and leave as soon as possible, and we have to return to Kyoto City as soon as possible." ”

At that moment, the four of them, who had regained all their strength, walked together to the ice door of the tomb door, and their four palms were attached to the ice door.

With the strength of the four of them, the huge and heavy ice door slowly opened inside.

As soon as the ice door opened, a huge ice mist erupted, Zhang Yi looked up, and saw that the tomb behind the door was surrounded by streams of ice fog at this moment.

Wang Yunfeng and Nie Qingchen walked towards the inside first, Zhang Yi and Master Fahong followed, this tomb is not big, it is one size smaller than the ice room outside, and there are huge thick ice layers all around, only in the center of the tomb there is a huge ice block that attracts everyone's attention.

This piece of ice is a rectangular shape, erected on a large ice platform in the center, like an upright ice coffin, which is very spectacular, and the height is at least more than two meters high.

After careful observation, Zhang Yifang found that the ice coffin and the ice platform under it were one, that is, this was originally a huge piece of ice, which was artificially chiseled.

The four of them stood around the ice platform, looked up at the ice coffin, and in this ice coffin, Zhang Yi really saw a golden sword-shaped thing inlaid inside, but the ice was too thick and looked a little blurry.

"This is the Xuanyuan Sword?" Master Fahong, who has always been unwavering, finally had a trace of surprise on his face when he saw the sword-shaped thing in this ice coffin, although he had been mentally prepared, but when he really saw it, he couldn't help but sigh.

Wang Yunfeng nodded and pointed to the ice coffin where he was standing: "Yes, according to my guess, this Xuanyuan Sword should have been a groove carved out of the front when it was put in, but after hundreds of years of changes, this groove was gradually covered with ice, and the Xuanyuan Sword was sealed inside." You see, when you look at it from my angle, the sword inside is much clearer. ”

Zhang Yi walked to Wang Yunfeng's side and looked in, and sure enough, from here, he could almost see the sword body that was sealed in the ice, and he couldn't help but be curious at the moment: "Then can we chisel this ice cube to take the sword?" ”

"This is no ordinary ice." Nie Qingchen stretched out his hand and stuck it on top of the ice cube, and suddenly a burst of cold air rose: "This ice cube is at least a thousand-year-old ice block, the hardness is harder than diamond, unless it is refined with extremely high temperature fire, it is possible to slowly melt it, otherwise even if you use an ordinary bomb, it is impossible to explode it, let alone use tools to chisel." ”

"The martial arts master who dug this ice coffin back then was extremely strong, and he should be the first generation patriarch of the Tianshan Sect, and only a peerless master like him could potentially cooperate with weapons to chisel this thousand-year-old piece of ice." Nie Qingchen said slowly, he had been studying this ice coffin for more than ten years, so he naturally knew much better than them.

Zhang Yi also nodded, in this extremely low temperature tomb, how high can the temperature of the fire be? Don't even think about bombs, you don't want to live if you blow up here. At that moment, Zhang Yi tried to hit the ice body with a palm, but the ice cube didn't even send out the slightest ripple.

Zhang Yi smiled bitterly: "The strength of the martial arts master of this sword back then was so strong, with the strength of the four of us, can we break this ice?" ”

"If we're all at the top of our game, there's an 80 percent chance we'll be able to break the ice." Wang Yunfeng said lightly: "Although the strength of the predecessors of this sword was strong, it was also the reason why they borrowed sharp weapons to chisel this ice, and with the combined strength of the four of us, at least they will be better than this old-timer, so the chance of breaking the ice is very great."

"Then let's start" Nie Qingchen didn't say a word, and took a deep breath.

At that moment, Zhang Yi, Wang Yunfeng and Master Fahong also began to use their internal strength.

After the four of them burst into a shout, the four of them slammed their palms on the ice coffin from four directions, and after receiving a heavy blow from the four people, the immobile ice coffin finally slowly trembled.

Of course, it was just a shudder, and then it was calm again.

Naturally, the four of them didn't think that they would be able to break the ice with one blow, so after sticking their palms to the ice coffin, they also closed their eyes separately, and shook the internal force into the ice coffin while carrying the internal force.

Once a strong destructive force enters the depths of this ice coffin, it will gradually destroy its internal structure, and then slowly spread outward, and wait until enough power fills the entire ice coffin, and the ice coffin will naturally burst open after it can't withstand this pressure, which is like injecting a bomb into it, and the explosion range is only inside the ice coffin, and it can't have any impact on the outside.

However, it also depends on whether the internal strength of the four people is not enough to support the ice coffin when it bursts, and if someone loses their internal strength halfway, I am afraid that their efforts will be wasted.

The four of them closed their eyes and didn't speak, feeling the subtle changes in this ice coffin after being injected with power, once they reached the masters of their realm, they could naturally feel the movement inside without looking at it, Zhang Yi could clearly feel that there was an invisible force slowly spreading in the depths of this ice coffin, and he could also hear the sound of the internal ice shattering from his heart.

I don't know how long it took, but finally, the entire ice coffin began to change, first slowly vibrating, the frequency from small to large, and there was a tendency to break away from the ice platform below.

Then, the sound of the ice breaking could be heard directly with the ears, and with this shattering sound was a crisp sound, and this sound was the sound of the sword shaking inside.

As the minutes passed, the frequency of the ice coffin's vibration became faster and faster, and the sound of the shattering became louder and louder.

Finally, just when the four of them felt that the internal force in their bodies was about to be exhausted, a boom suddenly came out, and just after this explosion, the exploding ice coffin turned into countless broken ice and rushed towards them.

The four of them had already prepared, and when the explosion sounded, they quickly gathered their strength and squatted down together, and pressed against the ice platform below, and the broken ice that burst flew around the entire tomb, and then it was inserted into the ice wall on the west side, you can imagine how great this power is.

With a "bang", a golden long sword was directly inserted into the ice platform below.
