Yang Lei was alone in the room at night.

"Ding, do you want to upgrade the system?"

"Nope. ”

You can't upgrade now, you need to exchange for something.

Now the things that Yang Lei wants to exchange are a purple lightning thunder cannon, a white dragon swordsmanship, and runes.

These three things are all necessary, the purple lightning strike cannon is a necessary thing to kill the Great Perfection of the Martial God, and the White Dragon Sword Law is what Bai Suzhen needs, because he only redeemed the first eighteen volumes before, and this White Dragon Sword Technique has a total of one hundred and eight volumes, and the original point value required was only five million points, but now it has become fifty million points.

In fact, Yang Lei could have exchanged it before, but because Bai Suzhen was in a state of cultivation and was not sober, it was not of much use to exchange it.

As for the other rune technique, it is also something that must be exchanged, the rune technique, if it is exchanged, it can help you refine your own weapons, and now if you want to upgrade your alchemy and refine more advanced things, you must ban the use of runes to achieve the goal.

"Ding, do players redeem the Purple Lightning Strike Cannon?"

"Redeem. ”

"Ding, congratulations to the player for obtaining the Purple Lightning Strike Cannon. ”

When the purple lightning strike cannon was exchanged, Yang Lei found that this purple lightning strike cannon actually needed a cannonball, this cannonball is the same as a spirit stone, in short, it is a thing that stores energy, and now the purple lightning lightning cannon is exchanged, and there is only one cannonball in it, that is, it can send out a blow tightly.

After taking a closer look, each of the shells of this purple lightning thunder cannon needs a top-grade spirit stone, and its power can kill the Tongxuan realm. One top-grade spirit stone is equal to one hundred, and the high-grade spirit stone is equal to 10,000 middle-grade spirit stones is equal to one million lower-grade spirit stones, and the exchange ratio is one hundred times

Yang Lei couldn't help but widen his eyes, he originally thought that he could kill the Martial God Dacheng, but now it seems that the power of this purple lightning thunder cannon is extraordinary, and it can actually kill the realm of Tongxuan, but unfortunately the price of this cannonball is too expensive, a cannonball needs a top-grade spirit stone, this top-grade spirit stone is a hundred top-grade spirit stones, and now Yang Lei only has a total of 100 top-grade spirit stones, no, plus the spirit stones in the Wuji Ring before, a total of one hundred and six high-grade spirit stones, fifty medium-grade spirit stones and more than 3,000 low-grade spirit stones, counting that he can only exchange a shell for a purple lightning thunder cannon now, which is too embarrassing, and the gap is very large。

Helplessly, I got this guy with 1.5 billion points.

Looking at it again, the Yang family breathed a sigh of relief, and found that there was a kind of cannonball with a little less power, this cannonball with a little less power could kill a martial artist in the Martial God Great Perfection realm, but it also needed a lot of spirit stones, and it needed ten high-grade spirit stones for one cannonball, that is to say, his current spirit stone could be exchanged for ten small-power cannonballs.

Gritting his teeth, Yang Lei decided not to exchange it first and see the situation.

Anyway, if you encounter an enemy, you can run away and then exchange it.

"Ding, have players redeemed the complete White Dragon Sword Technique?"

"Redeem. ”

"Ding, congratulations to the player for obtaining the complete White Dragon Sword Technique, a total of one hundred and eight volumes, and the consumption points are worth fifty million. ”

Fifty million points is nothing to Yang Lei, it doesn't hurt his muscles and bones at all, now Yang Lei is a rich man, he killed Qianyuelong and obtained 10 billion points, and he consumed 1.5 billion points for the purple lightning cannon before, and now there are more than 8.8 billion left, and if he consumes 50 million points, there are 8.8 billion points left.

Suddenly, Yang Lei remembered a serious matter, the system upgrade required one million points, but he exchanged the purple lightning lightning cannon and so on, and he knew that there were more than eight billion left, and there was not enough points to upgrade the system.

Yang Lei patted his head and secretly scolded himself for being stupid, he was so stupid, if he upgraded the system, although these things may be a little more expensive, but ...... But there are other things that can be exchanged, maybe after the system is upgraded, there are other things, cheaper, and you can also kill the strong man of the Great Perfection of the Martial God?

Regret, very regretful, Yang Lei couldn't help beating his chest, he was so stupid.

But now, it's useless to regret it, you can only wait until the points are enough in the future.

And this rune technique, there are only primary runes, intermediate runes, the points value of the primary runes is one million, and the intermediate runes need thirty million, which is nothing to Yang Lei, exchange, immediately exchange for intermediate runes, but unfortunately there are no high-level runes, if there is, Yang Lei naturally chooses to exchange for high-level runes.

"Ding, do you want to exchange for intermediate runes?"

"Redeem. ”

"Ding, congratulations to the player for obtaining the Intermediate Rune Technique. ”

After obtaining the intermediate rune technique, he naturally had to learn it, so Yang Lei immediately chose to learn.

"Ding, are you learning intermediate rune techniques?"

"Learn. ”

"Ding, congratulations to the player for learning the intermediate rune technique. ”

Of course, it's not enough to just learn intermediate runes, it's just learning, there are no real runes, how to carve runes? So to learn runes, there must be runes, and this rune is also exchangeable, Yang Lei looked at the runes that can be exchanged in the system, including accelerated runes, spirit gathering runes, and sharp runes, and now there are only these three, and the best ones are only intermediate runes, and there are no high-level runes.

Three kinds of intermediate runes, exchanging one rune all require 10 million points value, so the three intermediate runes are a total of 90 million points value.

"Ding, do players exchange for intermediate acceleration runes?"

"Redeem. ”

"Ding, congratulations to the player for obtaining the Intermediate Acceleration Rune. ”

"Ding, do players exchange for mid-level spirit gathering runes?"

"Redeem. ”

"Ding, congratulations to the player for obtaining the Intermediate Gathering Rune. ”

"Ding, do players exchange for mid-level sharp runes?"

"Redeem. ”

"Ding, congratulations to the player for obtaining the Intermediate Sharpening Your Rune. ”

Yang Lei thought about it, should he exchange for a primary rune? After all, although his rune technique has reached the intermediate level, it does not mean that when he is refining weapons, he can integrate the rune technique into the refining weapon so quickly, and he is still carving intermediate runes?

After thinking about it, Yang Lei still shook his head, this question, when refining the weapon in the future, if you can't engrave the intermediate runes, besides, it's not too late to exchange it at that time.

After redeeming so many things, the total value of points consumed is less than 1.7 billion, and now Yang Lei still has a little more than 8.7 billion left.

After consuming more than one billion, if you want to reach another 10 billion points, you need to kill at least two powerhouses in the Martial God Realm before you can reach 10 billion before you can upgrade the system.

In this case, do you want to exchange two low-power purple lightning strike shells?

After thinking about it, Yang Lei finally decided to redeem it.

Although he said that he would be able to complete the task of Tianxinglou in a few days, after killing the other person of Tianxinglou and hugging Chu Xiang, he would be able to completely replace Tianxinglou and complete the task, in this way, he would be able to get a rich reward, so that the point value would definitely not be less.

However, Yang Lei is worried that this task is not so easy to complete, and this Chu Xiang is not a guy to mess with, in order to be foolproof, it is necessary to exchange a few low-power shells, not too much, two, two can do.

"Ding, do players exchange for low-power purple lightning strike shells?"

"Redeem, exchange for two low-power purple lightning strike shells. ”

"Ding, two low-power purple lightning strike shells need to consume twenty high-grade spirit stones, are you sure?"

"Sure. ”

"Ding, congratulations to the player for obtaining two low-power purple lightning bolt shells, and consuming twenty high-grade spirit stones. ”

This is also a matter of no choice, twenty high-grade spirit stones really make Yang Lei's flesh hurt. Twenty high-grade spirit stones were consumed, and now Yang Lei only has eighty-six high-grade spirit stones left, if he wants to get a high-power purple lightning lightning cannonball, it is impossible, Yang Lei only hopes that after he kills Chu Xiang, he can get some spirit stones, or complete the task of replacing Tianxing Tower to reward spirit stones.

However, after exchanging these two low-power purple lightning thunder shells, his heart has also settled down a lot, this time even if a strong person like the Heavenly King Tiger comes to trouble him, he can also kill it, kill it completely, and make him his own experience value.
