The catalog page flashed, and a few lines appeared again: The spawn skill upgrade is successful, and at the current level, you have a 1% chance of mutation.

"One percent, the odds of this mutation are a bit low. Li Xi stared at the electronic screen and shook his head regretfully.

However, looking back, it is not bad to have a 1 percent chance of mutation. Still take the cash cow as an example, the copper coins on the cash tree, a thousand can be worth one or two silver ingots, and the mutation probability of one percent is equivalent to ten times higher out of thin air.

This is not the most important thing, the most important thing is the consumption of aura, for every hundred copper coins spawned, it will consume 0.3 points of aura, and a thousand copper coins, you need three points of aura. And to spawn a silver ingot, you only need to consume 0.1 of aura.

What's more, this mutation chance is almost white.

"Give it a try. Withdrawing from his consciousness, Li Xi thought about trying the first-level spawning skills he had just obtained, as well as the Qi Yang skills.

After thinking about it, I finally locked on the cash cow. There is not much spiritual energy left in the treasure book, and it is necessary to give birth to some more world money, offer it to the god of the stove, and ask Zhou Qingyuan about his illness. Therefore, Li Xi did not plan to waste his aura indiscriminately for the time being.

Take out the cash cow and place it on the table, first directly facing the cash cow and using the Birth Skill.

Spawn, spawn, spawn......

It's still against a point on the cash cow, using the spawn skill. The cash cow is a special tree, different from the general god fruit tree.

Divine fruit trees such as the Great Power Fruit and the Variety Fruit, the Divine Fruit spawned by the first-level spawning skill and the Divine Fruit spawned by the zero-level spawning skill will have a great upgrade in function.

However, the cash cow itself includes leaves and fruits, so even if you upgrade the spawning skill and use it against the cash tree, you can still spawn copper coins.

It's just that Li Xi obviously didn't realize this at first, and after using the birth promotion skill a few times, he couldn't help but be stunned for a moment when he saw that a leaf had grown on the cash cow.

"The first-level spawning skill, spawning or leaves?"

In doubt, go and check the Divine Tree Treasure Book.

The treasure book gives a reply: Level 0 spawning skills, used on cash cows, can only give birth to copper coins, and in the case of mutation, silver ingots, gold ingots, and even gem money may appear. The first-level spawning skill, when spawning, there is a 1 in 10 chance of one or two silver ingots, and in the case of mutation, there may be two or two silver ingots, five taels, and even gold ingots and gem money.

"Oh!" Li Xi suddenly said, "It turns out that the first-level birth skill can still give birth to copper coins, and it is also that on Li Zonglin's painting at the beginning, the money tree not only has gold ingots, silver ingots, gem money, and even leaves." ”

"The 1 in 10 chance is not low. Unless my luck is too bad, there will always be a silver ingot for a dozen copper coins. Coupled with a 1% chance of mutation, there may even be gold ingots and gem money. ”

"It turns out that there are two taels and five taels of silver ingots, but I haven't noticed them before. ”

"Continue to give birth and see how much faster it can be than before. ”

Sprout against the newborn leaves.

Spawn, spawn, spawn......

The leaves grow rapidly, and in the past, it took about 20 or nearly 30 spawns and skills to spawn. This time, the number of times the skill is used is obviously much less than before, about half less. As a result, it only took a dozen spawning skills to make the leaf a copper coin.

Li Xi grabbed the branch and shook it gently, and the copper coin fell off the tree. Picking up the copper coin, he took a look at it, and found that there was no difference from before, so he casually put it aside.

"Try it with Qi Yang skills. ”

Thinking of the newly acquired Qi Yang skill, Li Xi's heart was about to move. However, before using Qi Yang's skill, he still checked the remaining aura in the treasure book.

The remaining aura in the treasure book is 0.6.

"Qi Yang!"

Li Xi sincerely wanted to see how much aura Qi Yang's skill would consume, so he first used it once on the soil in the cash cow pot.

After using it once, check it again. It turned out that the remaining aura in the treasure book turned out to be 0.5.

"Once you use it, you actually consume 0.1 of the aura, and this Qi Yang skill consumes more aura than the aura consumed to give birth to the Divine Fruit. ”

Li Xi muttered, facing the cash cow again, using the Birth Technique.

"Give it a try, and see how much Qi Yang's skill, combined with the use of Birth, has a bonus to the effect of the skill. ”

Spawn, spawn, spawn......

After several spawns and use, a leaf appeared again on the cash tree.

When the leaf matured, Li Xi was surprised to find that the number of times he used the birth skill to give birth to this leaf had been reduced by nearly half again.

Just now, I used the spawning skill to spawn copper coins, and I used the spawning skill about fifteen times. This time, it was only used eight times, and a copper coin was born.

"It's a lot more efficient. ”

This result made Li Xi couldn't help but be surprised and delighted, "This Qi Yang skill is really good." With it, you can give birth to what you want faster. ”

"Go on, and see how many copper coins I can spawn with the little bit of aura consumed by Qi Yang's skill. ”

Excited, Li Xi continued to face the cash cow and use the birth technique.

Spawn, spawn, spawn......

For the cash cow Qi soil, the aura consumed by Qi soil has entered the soil. When it is born, the aura will also enter the cash cow from the soil, speeding up the effect of Li Xi's birth.

After eight spawning skills, another copper coin was spawned.

According to the previous experience in the use of spawning skills, a hundred copper coins will probably consume 0.3 of aura. If you have a 0.1 aura, you can probably give birth to about thirty-three copper coins.

However, considering Li Xi's Qi Yang skill, it is used in conjunction with the birth skill.

And the spawning skill, in the presence of Qi Yang, the effect is doubled.

The effect has been doubled, and if the aura consumed remains unchanged each time it is spawned, it means that half of the aura is consumed less.

Therefore, Li Xi estimated that the Qi soil skill used against the soil would probably be able to support himself to give birth to more than sixty copper coins.

But this is a theoretical calculation, and there will definitely be a deviation from the real reality. Considering the factors that the greater the ascension, the greater the consumption, Li Xi felt that most of Qi Yang's little aura could not support himself to spawn more than sixty copper coins.

Unfortunately, this idea was not accurately verified in the end. The reason is that when the thirteenth birth was born, a silver ingot appeared.
