Chapter 751: System Upgrade (1/2)

Within a couple of seconds, the spirit gourd consumed 1.2 million units of the essence of nature and upgraded itself twice.

Its current storage space is 100000 units; however, he can't use the essence of nature from the spirit gourd to upgrade his cultivation techniques.

'I think, the spirit gourd can be upgraded a couple more times,'

Since he still had 50.8 million units of the essence of nature, Ajax waited for the spirit gourd to upgrade itself; however, it never happened.

Instead of that, he received another system notification that gave him quite a surprise.

'Ding,

System upgrade is available. Do you want to upgrade it?

'Of course,'

Why would he not accept it? The last time it was upgraded, there were many changes to it. Even though it removed the level-up through the essence of nature, leveling up from completing the missions is also good; however, it took time for him.

So, he was hoping there would be some new changes to the system.

'Ding,

Originally, the system's upgrade would have been available after the host reached the general realm; however, because of the insane amount of the essence of nature, the system's upgrade is available before the host could break through to the general realm.

'Ding,

The system's upgrade requires 50 million units of the essence of nature. Do you agree to pay for it?

'What?'

The first system notification explained about the system upgrade and the second notification really made him shocked.

'If I didn't enter the bronze demon world, then how could I have upgraded you?'

Since the bronze demons were still hesitating to fight him, Ajax asked the system; instead of accepting it.

Just imagining it made him tired.

How long would it take to accumulate 50 million units of the essence of nature?

Moreover, it is even possible to find that many spirit beasts in the Zrochester province? Even if he finds that many spirit beasts, will the king of the spirit beast kings allow him to do that?

'Ding,

Even then, the host has to work hard and accumulate 50 million units of the essence of nature to upgrade the system.

'Sigh'

Ajax sighed as he allowed the system to consume 50 million units of the essence of nature to upgrade itself.

'Ding,

Deducted 50 million units of the essence of nature.

'Ding,

When the system is undergoing an upgrade, it will be temporarily unable to answer any of the host's questions; however, almost all features will work except for a few.

'Ding,

The second system upgrade's time is 12 hours. So, please wait until it's over.

'Ding,

The system's second upgrade will be started in 3...2...1.

Soon, a series of system notifications appeared in his head and the system went into slumber.

'I hope, I can still gain the essence of nature after killing the bronze demons,'

Ajax thought to himself as he looked at the bronze demons in the distance.

'Who would have thought that even four-meter bronze demons would fear me, a level 9 elite commander realm cultivator...Haha,'

Seeing the distant bronze demons, Ajax could not help but laugh out loud.

'By the way, battle-axe, what is the second condition to gain the knowledge on grade 4 weapon dao?'

Since he had already paid 110000 units of the essence of nature, Ajax asked about the second condition.

As for the extra 800000 units of the essence of nature, they were dispersed into the air after one minute of not using those units.

'Master, you have to swing a battle-axe by using the grade 3 battle-axe weapon dao for 1000 times.'

As soon as he asked, the huge battle-axe soul explained about the second condition.

'1000 times? It is not a big deal; however, for that, I need to find a good heaven grade battle-axe,'
