Whether the pattern carved on the black iron block was attractive or not, whether it survived or not, whether it was spiritual or not, these were of no help to Lin Cheng because he didn't know what the black iron block was!

Lin Cheng woke up from the door and couldn't help but smile and shake his head. He could scarcely remember how many times the expedition had failed. This made him realize that the seemingly extraordinary vision and wealth of experience he had accumulated over the lives of two generations were of no help or use in the exploration of Black Iron.

However, Lin Cheng is sure of one thing.

Black Iron, absolutely amazing!

"Of course it's special!"

Lin Cheng smiled bitterly and said to himself, "I don't know, I don't even know, can I enter the dantian?

When he took the exam at the Eastern Zhou Academy, Black Iron was like a bottomless pit that devoured all his inspirations.

"Suppress blue and blue flames in the endless Forbidden Land...... Only a slight tremor can suppress a real fire outbreak. It's scary to go out!

"Also, absorb the spirit stone veins ......"

This pile of piles, if it can't be proved that the black pieces of iron are extraordinary, then Lin Cheng really doesn't know what else can be called "extraordinary".

However, with his "superficial" insight, we simply cannot understand the origin of black iron, but this does not detract from the extraordinary and magical nature of black iron.

Of course, in Lin Cheng's opinion, strange is more suitable than black iron.

However, although we don't know the origin of the black iron block, Lin Cheng is not completely fruitless.

Through several transformations of the black iron block, Lin Cheng roughly summarized some rules.

First of all, the black iron block does not react to the original qi, only to the aura. For example, when taking an exam at the Eastern Zhou Academy, due to the stimulation of the spirit stone, the aura will be separated, causing the black iron block to move abnormally.

For example, in Zhujia Mine, because Lincheng sat on the spirit stone vein to practice, it not only absorbed the gas in the spirit stone vein, but also absorbed the spirit in the spirit stone vein, which once again caused the abnormal movement of the black iron.

Secondly, and most importantly, at the moment, Black Iron does not seem to have much adverse effect on him, and at the moment when the Blue Fire broke out, it saved his life.

Although I don't know why the black iron suddenly changed at that moment, at least Lincheng benefited from it. Therefore, Lincheng was a little lucky to get the black iron. Otherwise, in the Endless Forbidden Land, he would be reduced to ashes, let alone if he could get Blue Fire.

As for the absorption of the spirit stone veins by the black iron block, Lincheng was a bit strange. After getting the black iron block, he got some spirit stones from the storage bag given by Zhu Guangwei, but when he practiced, the black iron block did not react.

This made Lin Cheng speculate that the black iron block did not react at that time, did this have anything to do with him?

Because at that time, Black Iron had not yet entered his dantian!

Of course, this is just a guess, and Lincheng cannot confirm it at the moment.

Last but not least, Lin Cheng was most worried and worried about this. That is, the black iron is now in his dantian, and it still shines with the "spirit". So, if he cultivates with spirit stones, will it still be absorbed by the black iron?

If that's the case, he'll really cry without tears.

Of course, relying on your own efforts, you can steadily increase your physical strength, but that speed to increase your physical strength is almost hateful!

Relying solely on foreign aid to cultivate will indeed cause the disadvantages of an unstable foundation, burying hidden dangers on the road of maintenance, and I am afraid that it will not go far in the future.

However, this means relying entirely on external resources for self-cultivation. It is greedy, aggressive, and naturally unpopular.

However, if resources are used wisely, they will complement each other with their talents and efforts to make a difference.

If he only uses spirit stones to practice in the next step, he will be absorbed by Black Iron, then his progress will be slow and helpless. He was able to reach the peak of his chakra state in two or three years, which was very fast.

As for walking into Danhai, I don't know how long it will take. Even with the help of his own medical skills, the speed of cultivation is much faster than that of ordinary people. Compared with the spirit stone, there is still a big gap.

After all, the elixir was just a supplement, and the spirit stone could directly provide a huge and pure amount of energy.

"What do you think, thief, so upset?"

Zhu Qiao's crisp voice made Lin Cheng's thoughts reappear. He smiled back. Nothing, by the way, how did you practice the "Hot Sun Knife"?

Bamboo raised his chin and said proudly, "Do you want to try it?"

"Oh?"

Lin Cheng smiled and said, "You are so confident, it seems that you should practice the first move of this "Scorching Sun Knife" first, but not so slowly!"

"Why don't you believe it?" Takehashi snorted.

Lin Cheng looked her up and down, and the fox thought, "Really?

A smile flashed in Zhu Qiao Dali's eyes: "Then you will definitely be surprised." ”

Lin Cheng jumped up with a smile. He broke two branches from the tree and handed one to Zhu Qiao. He made a starting gesture: "Then try it!"

"Ahh

As soon as he spoke, Zhu Qiao suddenly stood up and attacked Lincheng.

At this moment, the branch in Zhu Qiao's hand was like a treasure knife. The long knife was cut off by the cold light of the knife.

Lin Cheng was suddenly taken aback. Zhu Qiao moved so fast that he couldn't dodge it for a while, even if it was too late.

Although Zhu Qiao had some unexpected factors, her speed itself was amazing enough, and with this strategy, she seemed to be very proficient, but it really made Lin Cheng feel a strong sense of irresistibility.

"Ahh

The next moment, the seven stars under Lin Cheng's feet stepped on the clouds, and then took a few steps back, pulling away from the slope of the bamboo pole, this was to dodge her knife.

After a move, Zhu Qiao did not continue to pursue, but raised his chin and said to Lin Cheng, "How is this girl's knife technique?"

With a hint of surprise in his eyes, Lin Cheng nodded and said, "Great!"

Indeed, Zhu Qiao gave him a surprise.

Although he had been teaching Zhu Qiao, a recruit, for many days, Zhu Qiao actually didn't have much time to practice, so Lin Cheng thought that she was the first to practice, and I am afraid that she was only the first. There is still a long way to go before skilled creditors arrive.

But Zhu Qiao's actual actions shocked him, because Zhu Qiao not only used his own skills, but, most importantly, combined his body with the "scorching sun knife".

Because of this, Zhu Qiao was able to fight so fast and powerful just now that Lincheng could not resist, so he could only retreat and dodge.

"Girl, if you continue to practice like this, it may not be long before you surpass me. Lin Chengdao said, "Now I'll teach you the second trick, cut off the current." ”

"Thief, you have to work hard, don't wait until the day really makes me catch up with you, and then you fight me again, and I'll knock you down!" Zhu Qiao chuckled.

Lin Cheng smiled: "That's better." I'm looking forward to that day!"

If one day Zhu Qiao can knock him down, it means that Zhu Qiao no longer needs his protection, and he can rest assured that he can take revenge, which is what he wants to see.

Zhuqiao didn't know Lin Cheng's thoughts. After playing with Lin Cheng with a subtle smile, he began to seriously follow the second trick "Powerful Dao".

"Ahh

Lin Cheng took a deep breath and sat cross-legged on the ground.

He was holding a spirit stone in his hand, and his demeanor was solemn.

From a distance, the bamboo bridge has entered a state of cultivation. She practiced the second move of the "Scorching Sun Knife" all day. Her physical strength has been depleted, and she is now recovering from her cultivation.
