Originally, Qin Xuan thought that this Spirit Gathering Technique would consume spirit stones like this, and the duration should be very long, not to mention that the gathered spirit qi could be worth the consumption of spirit stones, but at least more than half of it should be recovered.

But in reality, the duration was much shorter than expected, just an hour, and as the spiritual power of the spirit stones on the ground was exhausted, the rich spiritual energy began to gradually dissipate.

It didn't take long, about three minutes, for the aura concentration here to change to its original appearance.

"It's a bit of a pit. Qin Xuan, who was comprehending the earth shield technique, pouted, no wonder no one bought the rune paper of this spell, this effect is really chicken.

It can only last for more than an hour, and the concentration of spiritual energy has only doubled, and if you cultivate alone, the amount of spiritual energy that has been improved is not comparable to the amount contained in the two spirit stones.

The cost of this spell and the effect it brings are too different, unless there are some special circumstances, it is estimated that no one will use this kind of spell.

Having said that, what did Zhao Zhengqing do when he bought so many spirit gathering talismans?

Of course, Qin Xuan was just just curious, and soon, he put this question behind him and continued to learn the Earth Shield Technique.

In the previous hour, Qin Xuan had already comprehended the fireball technique, and even the earth shield technique was also comprehended for most of it, and it was estimated that it would take a while to be able to use it.

The principle of the fireball technique is not much different from the small fireball technique, that is, the way the spiritual power operates and some details have changed.

And the earth shield technique, although it has not yet been fully released, also has a general understanding.

Like the fireball technique, this is also an elemental spell that operates the spiritual power in the body through a specific trajectory, and then instantly merges with the elements to form spells.

After another while, Qin Xuan suddenly stood up.

I saw that his hands were quickly pinched, and in the next second, as soon as his spiritual power moved, an earth-colored shield appeared in front of Qin Xuan.

This shield looks very heavy, the right hand is stretched out, and the shield is maintained there with mana, and the left hand, in order to test the defensive power of the shield, directly throws a fireball technique!

"Bang!" After a muffled sound, the two collided, and smoke billowed out.

When the smoke and dust cleared, Qin Xuan found that the shield had not been pierced, but there was huge damage on it, and it seemed that it was estimated that one more fireball technique would be able to break it.

"Very good!" Qin Xuan nodded, these are all spells that Qin Xuan comprehended and then casually cast, they have not been strengthened by the system, it is already very good to be able to have this power.

Because the spiritual power in this situation did not fluctuate much, Qin Xuan dared to send it out, otherwise if he did it with all his might, he was still afraid of being discovered.

Huh, why is the little fireball column missing, and how did the proficiency of the fireball technique become so high?

He was only surprised for a while, and soon, Qin Xuan understood. The system automatically checks the correlation between spells, then directly compares them, combines them, and finally leaves more of them.

In this case, the system hides the one that is missing. Note that this place is just hidden, Qin Xuan has not forgotten it, it is just an upgrade.

For example, you learned math addition and subtraction, and then you learned multiplication and division. There is also an intercommunication between the two, and multiplication problems can also be done with addition and subtraction, but it is very troublesome, and the reverse is much easier.

In addition, the problems will also be varied, and the flexible use of these two methods can greatly improve the efficiency of problem solving.

And the current fireball technique is this principle, and Qin Xuan's use of it is very flexible.

The fireball seemed to come alive in Qin Xuan's hands, changing and terrifying!

This is very novel, Qin Xuan thinks it is good.

However, this freshness quickly passed, and the next thing Qin Xuan had to do was to add some points to these spells.

Now Qin Xuan had more than five hundred spirit stones on his body, and after thinking about it, Qin Xuan exchanged five hundred points.

Gathering Spirits, directly full, this is related to the next big order, he has to be the first to fill up.

And the Fireball Technique and the Earth Shield Technique, after thinking about it, Qin Xuan is also full, anyway, it is not bad for money, for things that improve strength, it is better to be full.

Because in this way, his strength will be stronger, and with it, his survivability will also increase!

If the talisman seal is first solved, Qin Xuan still doesn't care about it, anyway, his current talisman success rate is 100%, and the production speed is also extremely fast, there are no shortcomings, there is no need to strengthen it.

A few seconds later, as soon as the dots were added, Qin Xuan clearly felt that his comprehension of these spells had skyrocketed.

There is no need to mention the fireball technique, the power has increased several times, not to mention Zhao Zhengqing, even the black-robed man he met on the road before, Qin Xuan can easily beat him!

No way, the strength is strong, it's so inflated!

And the earth shield technique made Qin Xuan's sense of security rise significantly. After comprehending, Qin Xuan could use it flexibly, and the generated earth shield would not be as rigid as before, but just horizontal on his chest.

Now, Qin Xuan not only has a great increase in casting speed, but he can also generate an earth shield anywhere around his body, if he is not afraid of consuming spiritual power, Qin Xuan can even put on a layer of earth element condensed shield armor all over his body, so that his defense power will be greatly increased!

"Not bad! It's really good!" Today, Qin Xuan doesn't remember how many 'good' he said, anyway, he was in a very good mood.

However, by this time, it was almost midnight, and it had taken some effort to learn spells before, so Qin Xuan didn't continue to do things, and soon rested.

Time flies quickly, and in a blink of an eye, it's the next day.

During the day, there was nothing big about it, just to make a talisman and take Zhao Hu around the outer hall to find a suitable task for him.

In addition, paying attention to some news has also become something for Qin Xuan to do.

After all, Qin Xuan still has things to pay attention to, such as Yuan Fei's cousin and cousin. Although I am not afraid of them, if they find themselves, it will be a big trouble.

There is also the matter of Lin Yun and Ge Youde, the Demon Gate, Qin Xuan is very concerned, he subconsciously went to collect the news about the Demon Gate.

It's a pity that Qin Xuan doesn't have any control over these things now, everything is confused, and he hasn't received any news.

This is normal, so Qin Xuan didn't care, but waited for the night to come.
