It was indeed the river, and this time Sanzhi had found a way to escape into it, and brought the two of them in. When he got inside, he found that this was the hollow part of the peak, which had been washed by rain all year round, forming a river, but this river was in the peak.

Although I entered it, I found that the terrain here was very low, and it was still far from the ore veins above, and according to the position, the ore veins controlled by the Heavenly Dao Society were above. Fortunately, the river was winding upward, and the three of them climbed along the underground river, going higher and higher.

Later, the river became narrower and narrower, and finally they could not enter it anyway, so the three of them used weapons to chisel through the stone wall and open the way. After walking a little further, I saw a faint light from a rocky field in front of me.

The three of them hurriedly carved the way and crawled over, staring at the whitish stone wall for a moment. Long Nan was the first to ask excitedly: "Is it, is it crystal iron?"

Da Yuan and Sanzhi looked at each other and shook their heads, Long Nan immediately looked disappointed, but Sanzhi said: "Although it is not, it also means that this place is not far from the ore vein." ”

The two of them used their mana to dig up again, and saw that this whitish stone wall became harder and harder the further they went, and in the end they couldn't dig it anymore. Da Yuan motioned for the two to step back, then took out the silver snake sword and shot it out with enough mana. I thought that I could break some of the words this time, but I saw the silver light hit the stone wall, and the light was dazzling in an instant, and the silver light was bounced back, and Da Yuan hurriedly used the power of yin and yang with both hands to retract the silver light, this time the Dao technique was bounced back, and Da Yuan immediately felt bored in his chest, and it took a while to recover it.

At this time, seeing that Sanzhi and Longnan were also eager to try, Da Yuan hurriedly signaled the two to be quiet, and at the same time attached his ears to the stone wall to listen. Sanzhi said: "We seem to have dug up the boundary of the forbidden array, and we touched the formation just now." ”

Da Yuan nodded at this time: "I touched it just now, but fortunately I didn't alarm the Di Meng above, so I can't use it anymore." ”

The three of them pondered about the stone wall, and after a while, they couldn't come up with any good methods, this stone wall was already hard, and it was blessed by the forbidden array, if you don't use a strong spell, it can't be broken anyway, and then use a powerful spell will cause the reaction of the forbidden array, and the other party will notice, it's really a dilemma.

Seeing that Da Yuan and Sanzhi were helpless, Long Nan was lying on the stone wall and tinkering with something, and then a closer look saw that she used her unique little spell to drill a small eye on the stone wall.

Sanzhi only said: "What's the use of you drilling an eye?"

Long Nan only said: "Why is it useless, I just want to see if there is crystal iron ore behind this stone wall." ”

Da Yuan had already seen Long Nan cast this spell, and then his eyes suddenly lit up, and he smiled: "Why is it useless, it is useful!"

Seeing Sanzhi and Longnan looking at him suspiciously, Da Yuan only smiled and said, "If you teach me this Taoist technique, Longnan, I guarantee that I can drill a fist-like hole with my Taoism, and drill all the way to it." ”

Sanzhi: "And then?"

Da Yu smiled: "Then of course we use something to dig out the crystal iron piece by piece, who said that we have to let people in." ”

Sanzhi also said, "Okay, we can build a long iron hook to come back." ”

At this time, Long Nan rolled her eyes: "Who said that I would teach you this supernatural power?" ”

Da Yuan smiled and said, "Magical powers or something are far away, I can also teach you a Taoist exchange, how about it?"

Long Nan frowned and said, "Okay, Bai Jiao will teach you, but don't blame me if you can't learn it." You're all optimistic. ”

As she spoke, she walked up to the two of them, stretched out her five fingers and twisted them, and saw that an icicle immediately sprouted in front of those fingers, which spun at a rapid speed and dissipated after a while.

Sanzhi asked, "What kind of spell is this, and who taught you?"

Long Nan smiled proudly: "This Dao technique doesn't have a name yet, how about it, I practiced it myself, how about it?"

Sanzhi asked what kind of mana this spell used, how to control it, as well as mental spells and spells, but Long Nan shook his head and said, "How do I know so much, I just thought about it and sent it out." ”

Da Yu knew that Long Nan was telling the truth, she was thinking about it by herself, how could she be so exquisite, but if she wanted to learn it like this, it would be difficult. Da Yuan walked to the side and pondered slowly, first using the mixed element mana to convert it into ice mana, condensing it into a cylinder, and then using the method of yin and yang, pumping the cold qi to the other side constantly, and finally saw something coming out of Da Yuan's hand, the thing fell to the ground, but it was a small icicle, which really made Long Nan laugh for a while.

At this time, Sanzhi was not idle, the two of them hid in a corner and pondered, and from time to time asked Long Nan to demonstrate again, and the two kept practicing, just causing Long Nan to keep laughing happily.

was ridiculed by Long Nan a few times, Sanzhi's face gradually turned pale, and Da Qi's face became grim, both of them had a temper that drilled the horns of the bull, and they were even more focused on pondering. After a while, Long Nan was so angry that she lay on the rock and almost fell asleep, when she heard Da Yu laugh and said, "It's done." ”

Sanzhi was surprised when he heard this, obviously he had not mastered this inconspicuous spell, and Long Nan was also a little curious, so he only said, "Send one to try." ”

Da Yu nodded, and saw him walk to the stone wall, his hands circled and posed to complement each other, and he saw that the upper hand gradually showed a tumbling fire, and the other hand below showed a cold aura, and then Da Yu shook his hands, and saw that the two forces of blue and red were immediately twisted together, and they spun out very quickly, and they made a piercing scream.

Long Nan frowned and said, "What is this?"

Da Yu only smiled: "Although it is not the same as the Dao technique you issued, it is not too much different." ”

As he spoke, Da Yuan pointed to the stone wall, and when Sanzhi and Longnan took a closer look, they saw that there was an egg-sized hole in the stone wall, which had penetrated more than a foot deep into the stone wall. Long Nan still didn't care too much, but Sanzhi knew the difficulty of the Dao technique that Da Yuan had just issued, and couldn't help but look at Da Yuan twice.

Da Yuan smiled, and cast the spell on the hole again, and did it dozens of times, until Da Yuan was a little distracted, Da Yuan lay on the hole again and looked at it, his eyes lit up, and he smiled: "Okay." ”

Long Nan immediately grabbed over and looked into the hole, and saw that the hole had been extended more than a zhang deep, just leading into a vein, and you could see that the crystal clear pieces of crystal iron were embedded in the ore, and I saw Long Nan's smile like a flower, and his eyes were already full of shining things. Sanzhi also glanced at it, and immediately said, "You wait, I'll be back in a moment." ”

Da Yu knew that Sanzhi was going out to build an iron hook, so he rested and recovered his mana. After a while, sure enough, Sanzhi came back with an iron hook with a few folds in his hand, he straightened the iron hook and saw that it was more than a zhang long, and the hook had a tip in front of it to dig and a hook on the side, so he poked it into the hole, and then Sanzhi and Longnan kept chattering crookedly at the small hole, "Left, right, hey, right, left, okay!"

Soon I saw that Long Nan took a thumb-sized crystal iron to play with, and he was happy. Sanzhi and Longnan tasted the sweetness, and kept digging with iron hooks, and saw that pieces of crystal iron were dug out.

After a while, more than 20 pieces of crystal iron were dug out, but the progress of the next two slowed down, and when he lay down in the hole, he saw that the crystal iron near the end of the hole was dug up, and the other crystals were in the distance, and some could not be seen, and the iron hook could not be bent.

Sanzhi went out again, and wanted to build a longer iron hook back, but Da Qi frowned, thinking that this would not work, even if the iron hook was easy to use, how long would it take to mine a thousand crystals of iron, and the above Dimeng could be picked quickly.

Lying on the hole and looking inside, the big jacket only thought that it would be nice if people could get in, or if their own spells could get in. Entering, Da Yuan thought secretly in his heart, and suddenly his eyes lit up, he had already reached the Tao of two hundred and sixty years, and it should have reached the realm of the Yuan Shen out of body.

Da Yuan sat cross-legged on the rock, warned Long Nan not to disturb, and then sank down and entered a state of mind of forgetting things and me.

I don't know how long it took, Da Yuan only felt that the Lingtai was clear and clear, and his divine sense was accessible, and as soon as his mind moved, he felt that a wisp of his mind escaped from the Lingtai and came out of his true body. This Yuan Shen came with a ball of Xuan Qi and Mixed Yuan Dao Method, and flew straight into the hole.

This Yuan Shen can see it clearly, behind the hole is the mine hole, there is a lot of crystal iron, the Yuan Shen transported mana, barely dug out a piece of crystal iron, and flew back in his arms. The wisp of the primordial spirit put down the crystal iron, and when he saw his real body sitting cross-legged on the rock, he immediately felt shocked for some reason. Then he felt that the world was spinning for a while, and when he hurriedly opened his eyes, he saw that he was still sitting cross-legged on the rock, and what he had just seen seemed to be like in a dream, and he was already sweating profusely.

Da Yuan calmed down, and then saw Sanzhi and Longnan looking at him in surprise, and Da Yuan asked, "What's the matter, what did you see?"
