Are you crazy! You call this an assist?

"Lord City Lord, you are here, this man..."

The guard quickly said respectfully to Qianye.

Before he finished speaking, Qianye waved his hand and said, "Step back."

The guard immediately shut up and bowed to the side.

"Do you have all the materials?"

Immediately, Qianye looked at Jiang Chen with a little surprise in his tone.

"Um."

Jiang Chen nodded and prepared to take it out of his backpack.

"Put it inside."

Qianye waved, turned and walked into the city lord's palace.

Jiang Chen immediately followed.

The two came to the hall on the first floor of the mansion. There were still many rubbles and bricks that had not been dealt with, and it looked a little depressed.

"Just put it on the ground."

Immediately, Qianye pointed to an open space at his feet.

"good."

Jiang Chen responded and took out 100 earth element powders, 100 gold and iron essences, 100 earth crystal cores, and 100 bottles of magic energy springs from his backpack.

These things are like four small mountains, filling the open space.

Qianye glanced at the materials, then his eyes suddenly focused, he walked over quickly, squatted down and picked up a bottle of magic energy source.

He carefully looked at the black bottle in his hand, and there was a strange look in his eyes: "Is this bottle containing the magic energy source a black black star iron stone?"

"Uh...yeah."

Jiang Chen was stunned for a moment and nodded, then asked doubtfully: "Is there anything wrong?"

"Where did you get so many black black star iron stones?"

Qianye stared at the small black bottle with surprise in his tone.

"What's wrong?"

Jiang Chen looked puzzled.

"The Black Star Iron Stone has been extinct for many years. There are very few surviving ones, and they are all handed down from ancient times. Where did you get them?"

Qianye glanced at the pile of bottles on the ground again, his eyelids trembling slightly as he muttered: "There are still so many, how come there are so many..."

"Is the Black Star Iron Stone very precious?"

Jiang Chen asked thoughtfully.

"Precious and not precious."

Qianye looked at Jiang Chen and replied with a very contradictory sentence.

"What's the meaning?"

Jiang Chen frowned.

"This thing is extremely rare now, so it is naturally precious, but because the quantity is too small, it is useless." Qianye replied.

"Why didn't I understand?"

Jiang Chen frowned even more tightly.

"According to ancient books, Black Star Iron Stone will only work after a certain amount, and the greater the amount, the greater the effect."

Qianye explained: "There are so many black black star iron stones that can no longer be found, so naturally no one wants them."

"So, the Black Star Iron Stone has become of little value because the quantity is too small?"

Jiang Chen looked surprised. The rarer the other things, the more precious they were, but the Black Star Iron Stone was the less useful it was.

"Yes, I'm curious, where did you get these bottles?" Qianye asked again.

"Given it by a friend." Jiang Chen replied perfunctorily.

"Um."

Knowing that Jiang Chen didn't want to talk, Qianye didn't ask any more questions. He just looked at the bottle and sighed: "It will be useful if there are more."

"What's the use of it?" Jiang Chen looked curious.

"The Black Star Iron Stone is a defensive object, and it can be called the strongest defense!"

Qianye looked serious, not like he was joking.

"The strongest defense...is it so powerful?"

Jiang Chen was a little skeptical and confused: "Then why is it useless if there is too little?"

"Because it has a characteristic, the heavier it is and the larger it is, the stronger it will be. As long as the weight reaches a certain level, not even gods can break it!"

Seeing that Jiang Chen was still a little suspicious, Qianye continued: "For example, if the black star iron stone is used to make a pair of ordinary-sized armor, its defensive power will be average, but if there is enough quantity, it can be made The defensive power of a city gate is amazing. "

"It actually has this kind of characteristic..."

Jiang Chen felt surprised, and at the same time he remembered Hei Xuan's words before. It said that it could be beaten, but it was not a joke? !

Moreover, Heixuan could spill out so many black bottles with just a flick of his hand, which showed that this Heixuan star iron stone was not too much for it.

Coupled with the fact that it can grow in size, its defense is definitely not weak!

"You must ask Hei Xuan how big it can get!"

Jiang Chen felt a little hopeful in his heart.

"These Black Star Iron Stone Bottles should all belong to me."

At this time, Qianye's voice sounded.

"This needs to be added..."

Jiang Chen hasn't exported the word "money" yet.

"This is your reward."

Qianye raised his hand, and nine colorful light groups were suspended in the air. Among the light groups were gorgeous crystal keys.

"Nine keys to the door of reality!"

Jiang Chen couldn't move his eyes away at this moment, and the matter of adding more money was instantly forgotten.

After swallowing lightly, he quickly put all the colorful light balls into his backpack.
