"Then, I can continue to upgrade 4 times..."

Zhang Xiaoman looked at the system interface again and stayed on the upgrade option for a long time. Then he took a long breath and stretched out his finger to press it.

"Upgrades are being randomly selected, please wait..."

"Upgrade completed, the green prop Wu Fang Cao has been successfully upgraded to the green prop - Liuyang Flower."

Zhang Xiaoman paused after seeing the upgrade result, and moved his eyes directly to a small bottle on the side. The grass-like plant that was originally inserted on it was changing, and it grew rapidly from the top.

A red six-petaled flower came.

"Let me go, another recovery item has been upgraded. Is this the Liuyang Flower? It looks very ordinary. I don't know what its attributes are..."

Zhang Xiaoman stared at it and opened its properties panel.

【Liuyanghua】

Effect: Restore 120 points of health.

——The magical flowers that grow under the Golden Crow tree are said to bloom only once every sixty years. Eating them can restore a large amount of health.

Zhang Xiaoman didn't know if it was his imagination, but he felt as if the temperature around him had also risen a lot.

"This flower is really good. With 120 points of health, it should be able to cure an ordinary person from a serious injury."

He is still very interested in the upgrade of Liuyanghua. Although it will restore props like Baozi, the latter obviously does not have the possibility of being eaten in battle.

On the contrary, although Liuyanghua is not as loaded as steamed buns, it can be swallowed directly and is convenient for use in battle.

Anyway, for Zhang Xiaoman now, returning 120 and returning 300 are the same, both can directly heal the injury.

Moreover, Liuyanghua itself is not what he is most interested in. What interests him most is the new purchase authority opened in the mall, which is Wufangcao.

.

After all, Liuyanghua was not something he could easily use, and he wanted to save it for further upgrades, so his target could only be the Wufangcao that could be purchased.

I opened the mall list and looked at it. Wu Fang Cao had appeared on the shelf, and the price was 18 points.

Zhang Xiaoman looked at the buns on the side again. The Yuzhen Linglong Bag and the Eight Immortals Crossing the Sea were priced at 10 and 15 respectively, but he felt that he would have no chance to buy these two items in a short time.

"18 points can restore 80 lives, which is not bad. For the same recovery effect, it consumes 2 less points than two four-leaf flowers combined."

Thinking of this, Zhang Xiaoman suddenly discovered a strange place. The cost of upgrading the system is 10 points, and after upgrading, the price difference between some items and the previous level is more than this amount.

For example, the first-level Star Guard is priced at 200 points, while the second-level one is priced at 300 points, which is a full 100 points difference.

Some items are just the opposite, such as the steamed buns that were just upgraded. The ordinary steamed buns are worth 5 points, while the Yuzhen Exquisite Bags are worth 10 points. The difference is only 5 points, which is less than the 10 points spent to upgrade the system.

Although he still didn't understand the reason, Zhang Xiaoman suddenly had an idea in his mind to make a profit from the price difference.

Maybe in the future, I can buy a few more things that will increase my income after upgrading and save them, and then wait for the day when the system randomly upgrades them, then I can spend the minimum cost and get the maximum benefits.

However, he is not yet sure whether this method will work. After all, he does not have the extra points to try it now, so he can only wait until later.

After several draws, Zhang Xiaoman currently has 36 points left. The results are somewhat unsatisfactory, as there are no skills that are random enough to directly improve his combat effectiveness.

Shaking his head, he reached for the upgrade options again, intending to continue upgrading without stopping.

"Upgrades are being randomly selected, please wait..."

"Upgrade completed! The green item - Stone of Stars, Level 3, has been successfully upgraded to the green item - Stone of Stars, Level 4."

【Starry Stone】〖Level 4〗

Bound

After use, the dark energy will be restored to 100%, and the dark energy recovery speed will be increased by 100%. Duration: 1 hour.

Cooling time: 1 hour

——Using dark energy to successfully draw the pattern on it can transport the user back to the original boundary monument.

Zhang Xiaoman looked at the changed attributes above, and doubts suddenly arose in his heart. He didn't know whether the new recovery effect was good or bad, and he was a little unsure for a while.

After all, he doesn't have equipment that increases the effect of dark energy recovery, and that is the Polar Star robe that he often wears.

Judging from the natural recovery speed of dark energy, it would take about 10 hours to regain full energy. After putting on the robe, it would take 5 hours.

This attribute seems to be useless. If it is a good guy and the others, it may save some time, but after possessing the third-level Starry Stone, the 5-hour recovery time is really useless.

He calculated that with his current upper limit of dark energy of 183 points, he could recover about 0.3 points per minute on average, and after wearing the Polar Star robe, this value increased to 0.6.

It only took one minute to get 0.6 back, which is really useless and useless in battle. Instead of fighting, he can directly get back to full through the Star Stone, so he has never paid attention to this attribute.

Until now, he has obtained another prop with the same properties, which makes people have to re-examine this ability.

Zhang Xiaoman simply stopped upgrading for the time being. He waited for a while until the cooldown time of the Starry Stone in his hand ended, and then used it to return to Rebirth Island and refreshed a buff that increased the speed of dark energy recovery.

You won’t know until you try it. After trying it, Zhang Xiaoman was shocked to find that after he had the mana recovery buff and put on the Polar Star robe, his dark energy recovery speed suddenly increased from 0.3 per minute to 0.3 per minute.

Increased to 1.2 per minute.

This result was definitely beyond his expectation. He thought it would be good if it increased to 0.6 per minute, but what he didn't expect was that it increased so much all of a sudden.

It was only now that he realized that the increase in this attribute was not just a simple superposition of each other, but was calculated based on time!

In other words, if he has this attribute that increases the speed of dark energy recovery, the more he has in the future, the effect will rise in a straight line, and if he wants to get it back to full speed now, the time has changed from 5 hours to 5 hours.

2.5 hours.

Zhang Xiaoman is quite satisfied with this result. Not to mention the future, just based on his current upper limit of dark energy, he can recover 1.2 in one minute, which is considered a very good efficiency.

After all, in some long-term battles where he cannot escape, the recovery rate of 1.2 per minute can allow him to use many more skills.
Chapter completed!
