No matter how Yang Lei dodged, countless thunderbolts still bombarded Yang Lei's head mercilessly, and the power was getting bigger and bigger, and it was bearable at first, but gradually, Yang Lei felt that he was about to lose his bearing, and the whole person became almost unconscious, as if he was not his own.

"Boom", a huge thunderbolt struck, right in the middle of Yang Lei.

"Poof......

Yang Lei's whole person swayed a few steps, staggering, and a mouthful of blood spurted out.

Damn, this is a human life, Yang Lei looked at the thunderclouds in the sky, bitter, he can't use his true qi now, the space ring can't be opened, and there is nothing to do except resist.

If it goes on like this, it won't work, his little life is likely to be explained here, this cultivation room didn't say that it might cost people's lives, but it didn't say that it wouldn't cost people's lives, so for the sake of his own life, he had to find a strategy, find a strategy that could deal with this thunder.

It is not at all easy to deal with this thunderstorm, because he has nothing to do, so what can he use to resist this thunder and lightning? Resisting thunder and lightning with his bare hands is simply whimsical.

However, Yang Lei thought that this should be related to the power of the law, if he used the power of the law, he might be able to solve the problem, because these cultivation rooms are mainly for people to cultivate the law, so his true qi was sealed, and the space ring was restricted, but the spiritual power was still there and could be used freely.

Therefore, Yang Lei guessed, should this blue cultivation room mainly exercise his spiritual power, so that his spiritual power can break through and improve?

Otherwise, how can you limit your true qi?

For the cultivation of spiritual power, Yang Lei has only cultivated the Ice Heart Technique, and the Ice Heart Technique has been cultivated to the Great Perfection level, as for the higher-level spiritual power cultivation method, there is only one Divine Cultivation Technique, and the others have not been obtained, and the Divine Cultivation Technique that he has cultivated by himself is only the first level, but it is just some basic attack methods.

And obviously, the first layer of the Divine Technique that he is cultivating now is not enough to deal with the situation in front of him, if he wants to be able to deal with the situation in front of him, then he must get a higher level and a more powerful attack method, the first choice is naturally the second layer and the third layer of the Divine Refinement Technique, if you want to get this complete Divine Cultivation Technique, there is no way, because your own all-round cultivation system can still be viewed and exchanged.

First of all, Yang Lei clicked on the system and exchanged for some healing pills, after taking it, the injury was much better, but because the thunder and lightning did not stop there, but became more and more powerful, Yang Lei was also very helpless and had to resist.

I originally wanted to exchange for some equipment that can defend against thunder and lightning, but I found that to exchange for such equipment, the consumption is too great, and there are too many exchange points needed, so the gains outweigh the losses, and once you do that, it is estimated that you will not be able to have that kind of exercise effect, so Yang Lei still gave up this choice.

The only suitable thing is to exchange a mental method for cultivating spiritual power, which is the most important thing, of course, the first choice is the Divine Method, if there is anything more suitable than the Divine Method, then it is naturally the best.

In the system, Yang Lei clicked on the exchange system, and looked carefully at the options for exercises.

These exercises range from low-level to high-level, among which is the Ice Heart Formula, however, what Yang Lei is looking for is an improved version of the Ice Heart Technique, as for the Ice Heart Technique, he has already cultivated to the Great Perfection, so naturally there is no need to exchange it.

Yan Shen Jue, soon Yang Lei found the information of Yan Shen Jue, the first layer has been exchanged by himself, that is enough to consume his own 50 million exchange points, this Yan Shen Jue has three hundred and sixty-five volumes, and he has only exchanged one volume now, and he has only studied this first volume.

This time, Yang Lei plans to exchange all the first five volumes of the Divine Formula, originally the first volume has been learned, and it can not be exchanged, but alas, this system is too tricky, there is no possibility of separate exchange, if you want to get the second volume to the end of the four volumes, the first volume must also be exchanged.

But Yang Lei had no other choice but to exchange.

There are quite a few exchange points needed to exchange the first five volumes, and one billion exchange points are needed.

One billion exchange points, that's not a small number, although I now have tens of billions of exchange points, but I also have to feel a little painful, and this is still the result of only exchanging the first five volumes, if you want to exchange them all, get a complete trick, it is estimated that the required exchange points will reach 100 billion, or even trillions are possible.

"Ding, do players redeem the Divine Formula, Volumes 1 to 5?"

"Redeem. ”

"Ding, congratulations to the player for obtaining the first to fifth volumes of the Divine Formula, and consuming one billion exchange points. ”

The trick is in hand, and the rest will be seen later, and then learn this trick first.

"Ding, do players practice the second volume of the Divine Formula?"

"Cultivation. ”

"Ding, congratulations to the player for learning the second volume of the Divine Formula. The system prompted again, Yang Lei felt that there were a lot more things in his brain, and his mental power had improved a lot, compared to before, his mental power had at least doubled, or even surpassed. And for the mastery of spiritual power, it is even more like a fish in water.

What especially pleased Yang Lei was that in the second volume of this magic trick, there is a secret method about the defense of spiritual power, the spiritual power shield, which materializes the spiritual power and forms a shield to protect himself.

Of course, there are some methods of attacking, which is to use spiritual power to drive objects to attack, but for Yang Lei's current situation, there is no benefit, because there is nothing else here to drive himself.

This reminded Yang Lei of the swordsmanship, which is actually similar to the swordsmanship.

"Ding, do you want to continue to cultivate the third volume of the Divine Formula?" At this time, the system heard a prompt sound again.

The third volume of the Yan Shen Jue, of course, is cultivation, and the stronger the strength is now, the better, after all, his cultivation realm is just gossip and condensation, and the requirements of the blue cultivation room are probably at the level of heavenly immortals, or even higher, although he can use the two forms of the Heavenly Sword and the Hand of Great Creation to kill the cultivators of the Heavenly Immortal Realm, but not here, the Hand of Great Creation and the two forms of the Heavenly Sword cannot be used, so the strength that he can really exert is only the level of the Nine Extremes of Creation and Transformation, which can be used against the early stage of the Heavenly Immortals.

Therefore, there is no need to think about whether or not to learn the third volume of this magic formula.

"Ding, learning failed. ”

This voice made Yang Lei stunned, failed, actually failed, his current strength is not enough to learn the third volume of this derivative formula?

This situation actually occurs, this is something that I have never encountered since I got the all-round cultivation system, although at the beginning, after I exchanged the Ice Heart Technique, I could only cultivate layer by layer, but if the system has a situation of prompting whether to learn, I can generally learn it directly, and now there is a special event of learning failure, which makes Yang Lei unexpected.

Or you should try again yourself.

Thinking of this, Yang Lei went to study for the second time, but the result was the same as before, and he failed.

Helpless, Yang Lei knew that this might not work, and it was estimated that he needed to cultivate by himself, but Yang Lei also knew that if he studied and cultivated by himself, he would definitely not have the help of the system, so fast, just like the Bing Xin Jue he cultivated, it took so long to cultivate to the Great Perfection.

Of course, it is impossible to achieve cultivation overnight, so Yang Lei is also clear about this, since he can't use the system and learn it all at once, Yang Lei doesn't have too much loss.

After figuring out this, Yang Lei immediately withdrew from the system, and now the task is to fight against this thunder, which is the main task.

Looking at the continuous thunder, Yang Lei's face was solemn.

At this time, although the frequency of the thunder attack was much smaller, the power was getting bigger and bigger.

At this time, the thunder did not come down, and the many thunderclouds in the sky seemed to be giving birth to a strong attack, as if they were going to crush Yang Lei at once.

Yang Lei's mood is also quite heavy, before he resisted the thunder, his body was not lightly injured, although he took the healing pill, but to recover completely, it still takes time, and this thunder and lightning continue to attack him, the medicinal power is also consumed very quickly, and the consumption of mental power is even more intense, if it is not because he has cultivated and learned the second volume of the Divine Formula, the spiritual power has recovered quickly, and has been greatly improved, at this time, he is estimated to be unable to resist.

Looking up at the thunderclouds in the sky, the arc of electricity kept flashing, like a giant beast in the wilderness, trying to tear apart and completely destroy the guy in front of him who dared to provoke his majesty.

"Boom...... Rumble......"

Before the thunder and lightning fell, the earth-shattering sound was deafening, as if announcing its might.

"Click. ”

Suddenly, a huge arc of electricity slashed down, the speed was extremely fast, and it came to Yang Lei's head in the blink of an eye. Yang Lei had already taken precautions, raised his hands, and shouted violently.

A shield was instantly condensed in his hand, this was not an ordinary shield, but condensed by using his powerful spiritual power, and his spiritual power was materialized. At the moment when the shield collided with the arc, the entire space was illuminated by the strong light emitted during the collision, making it almost impossible to open one's eyes.

"Click. ”

Hearing this voice, Yang Lei secretly said that it was not good, the shield was broken, and he couldn't hold on, Yang Lei was shocked, was he going to fail? This shield has condensed 90% of his spiritual power, unwilling, unwilling to fail, will not give up, Yang Lei gritted his steel teeth, looked at the thunderclouds in the sky, and once again condensed the little spiritual power left in his body, and continuously entered the shield.

"I'll definitely block this blow, damn Thunder Tribulation, and see how I break you. Yang Lei burst into a shout, a strong light flashed in his eyes, and the whole person burst out with a strong desire to win.
