After finding an emperor beast to fight, raising the energy basic sword technique and primary energy shield to a lesser level, and tasting the flesh and blood of the emperor beast, Lin Fei was idle, planning to learn about the Tianyuan Crystal Wall.

"This is the Tianyuan Crystal Wall?"

This thing is much more beautiful than expected, Lin Fei thinks so.

Holding a glittering crystal in his hand, the inside is full of surging power and essence at the same time.

"Ding, find the Tianyuan crystal wall, whether to absorb it!"

"Ding, find the Tianyuan Crystal Wall, do you want to exchange it!"

Immediately the system prompted.

Absorb and exchange?

The meaning of the former, Lin Fei understands very well, the latter, can also be exchanged?

"Redeem!"

Lin Fei chose the latter, wondering what it would be exchanged for.

"Ding, the exchange is successful, and you get 1 progress. ”

With the sound coming from the system, Lin Fei found an interesting thing, that is, on the attribute information page, there was an extra progress bar behind the original power output.

1/100000000。 (100% progress, upgradeable!)

Lin Fei was overjoyed, "I'm still wondering, how to improve this limit, it turns out that I need a Tianyuan crystal wall, so I don't need 100 million Tianyuan crystal walls!"

This discovery made Lin Fei very happy.

Although the output is between 100 million and 300 million, it seems to be very powerful, Lin Fei has never thought of himself as invincible, but he has an advantage over others.

"Is Tianyuan Crystal Wall easy to mine?"

Lin Fei casually asked Yuan Thirteen.

"It's hard to mine, the Tianyuan crystal wall is extremely hard, and you have to cooperate with the envoy to mine the tools. in order to carry out a certain amount of mining. ”

Lin Fei waved his hand, "Tell the point." It's all nonsense, I just want to know. How much can be mined in a year, for example, your Heavenly Wolf War Emperor. ”

"I remember that last year, a total of more than fifteen million pieces of Tianyuan Crystal Wall were mined!" Yuan Thirteen said after thinking about it.

Lin Fei rolled his eyes, "Damn, the yield is so low." ”

Thinking about it, if the Tianyuan Crystal Wall was so easy to mine, the Divine Emperor Mountain would have been broken by someone a long time ago, and it would not have fallen into his hands.

"Your Excellency. This is already very high, for a few years, the Tianyuan crystal wall mined every year was less than half of last year's, only a few million!"

Hearing that number, I chuckled.

Millions a year, I can only accumulate 100 million pieces of Tianyuan Crystal Wall in the Year of the Monkey.

"You have to find out for yourself!"

Lin Fei is very confident that as long as he has checked the situation on the spot, he should be able to come up with a good solution with his own system. Increase the efficiency of mining volume.

"Take me to the nearest mine!"

Yuan Thirteen is now out of the way.

Soon, a mountain range appeared in front of the two of them, and there was a huge valley in the middle of the mountain, and the valley was heavily garrisoned on all sides.

"Your Excellency. This is a mining area of the Heavenly Wolf War Emperor, and he has a total of six mining areas in his hands, this mining area. You can mine two million pieces of Tianyuan Crystal Wall in a year!"

Lin Fei didn't use his divine sense, he used the system to scan.

around the mountains. The number of heavy soldiers is about 10,000, all of which are equipped. At the same time, the realm is not low, they are all in the realm of the God Emperor, and there are many invincible God Emperors.

"In the space of God Emperor Mountain, are there a lot of mining areas?"

Lin Fei asked Yuan Thirteen.

"I heard that there are a lot, however, many places are occupied by powerful emperor beasts, and even some places are occupied by fierce beasts at the war emperor level, and now these mining areas are all snatched from the hands of emperor beasts!"

Lin Fei's eyes lit up, this was good news.

"Alright, you're here waiting for me to come back!"

Lin Fei threw down a sentence and sneaked into the mining area.

The mining area is huge.

Lin Fei found that the people who mined here were basically gods and respected their strength, holding special tools in their hands, and entered the mine with expressionless faces.

"Good guy, there are actually two guys from the Seventh Turn of the God Emperor here!"

Lin Fei blocked all the aura, even if the Emperor of War was here, he didn't want to find someone sneaking in.

This time, Lin Fei did not come to kill people, but sneaked into the mining area to check the specific situation, and avoided patrols all the way, Lin Fei quietly came to the mine.

The mine was very large and extended in all directions, and Lin Fei found a remote place.

In the passage, someone was holding something like a hoe, clanging and beating, and every time he hit the rock, the miner burst out with terrifying strength, and the rock actually didn't move.

"Open!"

Lin Fei showed his figure, opened his five fingers, and grabbed the nearest rock, under his strength, no rock could withstand a grasp, but this time, he was going to be disappointed, this time he grabbed it, Lin Fei seemed to have grabbed an iron plate, a huge shock, and his body shook.

"What a hard stone!" Lin Fei was shocked, "The power I exported just now was almost about 50 million, and it was actually shocked, come again!"

This time, Lin Fei exported 80 million strength, and he didn't believe that the rock could be so hard.

Boom!

Lin Fei was rebounded again, and the power was very great, directly rebounding the power just now.

"This rock is not simple!"

Lin Fei shielded this place, not worrying about the breath leaking out.

"Come again!"

Bang bang bang!!

Lin Fei really had something to do with this thing.

Every time the power is increasing, from 50 million power output, all the way to 300 million power output, unfortunately, the rock shows strange characteristics, every time the power rebounds back, very evil.

"No wonder the mining efficiency is so low in a year!"

Being rebounded again, Lin Fei let out a long sigh and really understood why the mining efficiency was so low, not for no reason.

"I can't shake the rock with my strongest power output, I really need special props!"

Lin Fei no longer experimented.

Even if it is to output a billion powers, it may not be able to break through, and this rock is very evil.

"Scan this rock for me, I want to know what's in it!"

Although Lin Fei is helpless to take the rock, it doesn't mean that he can't do anything.

Isn't it just the consumption of a destiny point, this is easy to say, Lin Fei just wants to know what the reason is.

"Ding, find a special rock, level: 0 has a special ability, ignores all attacks, and has 100% reflected damage!"

Lin Fei suddenly realized, daring to love this is a special rock, and he also has certain skills, which is really an eye-opener.

Served!

The previous repeated reflexes were easy for Lin Fei to block, and those who didn't know couldn't be killed on the spot by themselves.

"If they can mine it, they must have mastered the way to deal with special rocks!"

Lin Fei's figure disappeared, and he came to another mine, killed one of them, snatched the mining tools from the other party's hand, and threw an appraisal at the same time.

"Pickaxe, Grade: 1 is made from the trunk of the Senluo Iron Tree. ”

Lin Fei smiled.

"It was originally made from a special tree, no wonder it can ignore reflected damage!" (To be continued......)
