"The upgrade is still very fast, so don't worry. System 766 replied with a smile.

"In that case, how do we need to level up, and do we also use points to upgrade? Yang Tianfan continued to ask.

When System 766 heard this, he smiled, and then continued: "No, after that, the upgrade will need to use salt water, and with the watering of salt water, the upgrade here will also be accelerated." ”

Salt water irrigation?

Tang Xiaohan was a little stunned after hearing this, he really didn't know what this had to do with the watering of salt water, did they need so many things to complete a task now?

"Salt water irrigation, what salt water, how to water, are there any requirements?" Tang Xiaohan stepped forward and looked at System 766 very nervously and asked.

"Yes, the brine used for brine irrigation must be the brine purchased outside, and the products purchased in the system mall are of no use and will only waste your points. ”

"Really?"

Thinking of the money they had earned by working hard outside during this time, they were also a little relieved, after all, the money they earned was enough to buy salt at present.

"Yes, the salt needed must be bought outside, because the Rubik's Cube tree is a combination of sunlight, air and sodium chloride. If you upgrade to level 7, you can complete it in about 15 days, of course, I'm talking about upgrading from level 3 to level 7. System 766 adds.

As soon as he heard the 766 words of the system, Yang Tianfan sensed the trap in this sentence, and asked a little incredulously: "Could it be that there are still other tasks after the upgrade is successful?"

"That's right, after the system upgrade here, there will be worlds, tasks waiting for you to complete, every time you complete a task, your vitality to create a human can be restored once, until it is fully recovered, you can get pregnant. System 766 said. Nuancai Literature Network

It's a bit awkward, and it's going to take time to wait.

"If we conceive naturally, how long would it take? "If you don't use the space-time Rubik's Cube tree, wouldn't your time be about the same?

If it's about the same, you can save this amount of points without it.

"If we had conceived at the rate of natural pregnancy, we would have been able to conceive in about three and a half years. "I heard that the system actually said that it was 3 and a half years later?

Tang Xiaohan and Yang Tianfan were a little shaken.

"Let's buy it, let's buy a level 3 Rubik's Cube tree, and we'll talk about upgrading when it's done. After Tang Xiaohan listened, he said directly to Yang Tianfan.

Hearing this, Yang Tianfan also nodded, after all, they had heard the words of System 766 just now, instead of being conceived naturally, they still chose to buy the space-time Rubik's Cube tree.

After having the space-time Rubik's Cube Tree, it will be equivalent to two people The plan can be taken slowly, and if the space-time Rubik's Cube Tree can be faster, they can also complete it as soon as possible.

But just in case, Tang Xiaohan still asked System 766: "Then if we use the Time and Space Rubik's Cube Tree, how long is our slowest time?"

Tang Xiaohan didn't actually have any answer to this question, after all, they had all been waiting for so long now.

"Yes, a year, the longest at the moment is a year. ”
