Ni Feng didn't seem to be telling a lie when he heard the voice of the machine spirit, and after a deep sigh, he said to the machine spirit: "Well, you swear to the sky, if I save you, if you don't keep your promise, you will be wiped out!"

The machine spirit swore without hesitation, and then said to Ni Feng: "Brother, it is easy to say that it is easy to say that it is difficult to break this crack, and it is difficult to say that it is difficult, but with my brother's skills, I can tear this crack open by attacking the crack for a while at most, and I will be able to come out." ”

"This crack, as long as it is attacked, part of the power of my seal will be converted into the power of attack to hit you, you have to keep attacking, because the power of my seal will recover with the passage of time, so keep attacking. The machine spirit admonished again.

Ni Feng nodded and said, "Since I promised to save you, I will definitely do my best." ”

With the restraint of the oath, Ni Feng finally put his mind at ease and walked towards the crack, and at the same time, the mana of his whole body was running, adjusting himself to the best state, preparing for a long time to attack and dodge.

Ni Feng came to the position just now, took a deep breath, and wiped it on the storage bag, in a flash of green light, the remnant sword appeared in his hand, and then the mana poured in, the green light flashed, and a sword slashed towards the crack.

A sword ray of dozens of zhang in size flew out from the remnant sword and landed straight on the crack, "Bang!" A sound came, and where the sword shone, a bucket-thick lightning shot towards Ni Feng at an extremely fast speed.

Ni Feng had already prepared, and as soon as his mind moved, he shifted nine times, moved out horizontally for dozens of zhang, and then slashed away with a sword, and in the blink of an eye, another lightning bolt shot towards him.

"Brother. You can't go on like this, you have to use powerful spells. Otherwise, if you chop around like this, you will have to split it until the Year of the Monkey and the month of the horse. The voice of the machine spirit came out again. fell into Ni Feng's ears.

"Got it!" Ni Feng increased the infusion of mana, and a sword slashed down, and suddenly the sword light changed from dozens of zhang to hundreds of zhang, and fell on the crack. At the same time, a hundred-zhang-sized bolt of lightning shot out from the crack, as if Ni Feng would return as much damage as Ni Feng attacked it.

Ni Feng's body kept flashing, and kept slashing out the sword for a while. He didn't know how many swords he had slashed out or how many bolts of lightning he had dodged.

"Brother, work harder, the power of the seal is getting smaller and smaller!" came the excited shouts of the machine spirit from the crack, and at the same time, it also cheered Ni Feng and let him cheer up!

Finally, as Ni Feng kept swinging his sword, the voice of the instrument spirit in the crack became more and more excited. Finally, there was a louder scream, and with a "click" sound, the crack was full of cracks. Finally, it collapsed, revealing a hole that was more than one zhang high and one foot wide.

"Brother. It's okay, it's okay!" the machine spirit shouted excitedly at Ni Feng. Ni Feng's hand suddenly stopped at this time, and he was relieved in his heart. Fucking it finally succeeded. At the same time, he also felt the loss of a trace of his divine power.

Ni Feng wiped his sweat, put away his sword, and walked towards the entrance of the cave.

After a while, Ni Feng came to the entrance of the cave, only to see that this is a natural cave, this cave is the size of a hundred zhang, in the middle of this cave, there is a stick, a golden stick, at this time is emitting a faint golden light.

"Brother, I need to re-fuse the artifact, wait for me for three days. The voice of the machine spirit came out from the golden stick, this golden stick, no more than a foot high, only the thickness of the baby's fist, the stick is carved with some lines, very regular, take a closer look, it turned out to be carved a monkey, the movements are different, as if practicing a set of martial arts.

"Brother, what is carved on the artifact is the supreme stick method of the Fighting Saint Ape Clan, except for the Fighting Saint Ape Clan, other races cannot cultivate, if you forcibly repair it, you will only go mad and die!" reminded the machine spirit.

"I don't want to learn. Ni Feng pursed his lips, then looked away from the golden stick and landed in the cave.

"Brother, those shining stones in this cave are all the best materials for refining artifacts, don't take them all, leave me a little, and after the fusion, I need to use them to restore my vitality." The machine spirit said again.

"Got it, you're so long-winded!" Ni Feng glanced at the golden stick angrily, then came to a glowing stone, paused, and touched it with his hand, these glowing stones, he had never seen them, he wanted to pick them up, but he couldn't lift them, as if they were rooted, and they were linked to the ground.

"Grass, why can't it be broken?" Ni Feng tried hard to break the stone from the ground, but no matter how hard he tried, the stone did not move.

Ni Feng didn't believe in evil, took out the remnant sword again, and slashed down at the stone with a sword, as a result, with a "bell", the sparks shot in all directions, and there was a burst of pain from the tiger's mouth, and the stone was just cut off by the remnant sword An inconspicuous trace.

Ni Feng knew how powerful this sword was, but the stone was unharmed, as if it had not been affected in the slightest.

"Why is it so hard!" Although Ni Feng said this, he couldn't help but get excited in his heart, these stones seem to be really amazing miracles, although he doesn't believe that the so-called artifact can really be practiced with the material of these stones, but it is absolutely possible to refine the magic weapon, and even to refine the legendary immortal weapon, it is also very possible.

In order to get this stone, Ni Feng simply acted as a fool, and slashed at a place on the stone in front of him with a sword, and in the end, it took him a whole day to cut this stone off the ground.

This is a palm-sized stone, in his hand, it is very heavy, Ni Feng estimates, at least about a hundred catties, a palm-sized stone, a hundred catties, which makes Ni Feng a little surprised, he has never seen such a thing.

Ni Feng looked at the stone in his hand for a while before putting it away, and then walked towards a stone next to him, although he didn't know what these stones were, but if he took them out and showed them to his master, they would definitely know each other.

Ni Feng was right, if Tang Jie and the others saw these stones, they would definitely go crazy, because these stones, even they had only seen them in ancient books, they had never seen them in reality, these stones were superb materials for refining immortal weapons, and in the Five Domains, except for the Ancient God Domain, the other four domains were peerless materials that had long been extinct.

This stone, called Tianjing, is an extremely rare refining material, this Tianjing, even if it is placed in ancient times, it is also an extremely rare treasure, how can this not make Tang Jie and them crazy?

Ni Feng cut down a piece of celestial crystal one day, in this cave, there are not many celestial crystals, scattered in the cave, Ni Feng counted it, there are only twenty pieces.

In the end, Ni Feng spent four days chopping down four pieces, and in these four days, he didn't take a break, and all of them were used to chop stones.

On the fifth day, the golden stick suddenly burst into golden light, instantly illuminating the entire cave, and Ni Feng was so pierced by this golden light that he couldn't open his eyes at all!

"Hahaha! Finally free, finally able to go out!" the voice of the machine spirit came from the golden stick, with great excitement and excitement. (To be continued......)
