After Keiko left with the candle spirit, he released the elf.

He looked at the elf and asked with a complicated expression, "Elf, Keiko is the mount you said before, I should meet?" ”

"The benevolent see the benevolent, and the wise see the wise." The elf replied.

Zhang Sen was speechless, and it was another doctored answer, but from this answer, you can know that it should be an elf.

Then he thought for a moment and asked, "Elf, why did Keiko transform?" ”

This question should not be tampered with.

Sure enough, the elf replied: "Keiko once took the perpetual motion stone fragment, and the fragment was stained with the blood of the immortal bird dragon, so its bloodline was polluted, and in the process of death and resurrection, its body mutated, and it has a unique transformation ability. ”

"Then its transformed image is an immortal bird dragon?" Zhang Sen immediately asked.

The elf denied, "It's not an undead bird dragon, it's a new lifeform, and it's not named yet. ”

"I see, what can I do to prolong its transformation time?" Zhang Sen nodded, and then asked.

The elf replied: "The more energy Keiko has in her body, the longer it will take to transform, and the first method is to repeatedly overeat, gradually increasing Keiko's food intake, thereby increasing energy reserves." Method 2: Learn the Dragon Clan Exercises to transform your body and hold more energy. Method 3: Inject energy-absorbing agents to modify cells, and unknown mutations will occur to a certain extent. Method 4......"

There are many, many methods, there are tens of thousands of methods, and Zhang Sen has written them all down.

After figuring out the problem, Zhang Sen directly rejected method 1 and method 2, because neither method can be achieved overnight, although it is the most safe, but it takes a long time to implement, which is simply unrealistic.

When Keiko really masters the huge amount of energy, I'm afraid that the daylily won't know that it has been cold for thousands of years.

Therefore, the most suitable method is method three, scientific transformation.

In fact, it is not that it is impossible to cultivate after scientific transformation, but there may be some sequelae.

Under normal circumstances, different systems will only insert some things that do not conflict with their own cultivation, for example, the Sword Immortal can also install a missile launcher on his flying sword, which will not have any sequelae, although no Sword Immortal will do this at all.

In the same way, the technology system generally rarely uses the stuff of other systems, and even if it is a combination of studies, it will avoid conflicts.

For example, the witchcraft system generally only chooses the Shinto system, while the monastic system generally chooses the immortal system, and it is rarely mixed with other systems.

Ordinary people must have the consciousness of ordinary people, if they always feel that they are the chosen ones, the most special one, then the reality will often soon slap their faces.

Zhang Sen has always maintained his self-awareness, at least he never felt that he was special, although he had his own golden finger, but he was not crazy enough to kill the whole family at every turn.

Although the Yellow Emperor once said that if the resources are sufficient, he can repair any system at will, but in fact, this is just standing and talking without backache.

After all, all roads lead to Rome, and any system may end up having the same place, but at least don't mess around until you're completely in control.

Zhang Sen learned a lot of intermediate and advanced common sense in the Eternal Kingdom, which is just not available in other worlds.

In fact, the words of the Yellow Emperor are also right, and the common sense of the eternal country is also correct, but the level is different.

In the eyes of the Yellow Emperor, all systems have only one apex in the end, and there is no conflict at all, after all, he has already stood at the apex.

As for the high-level cultivators of the Eternal Kingdom, they plan their cultivation path more carefully, and eliminate all drawbacks, suppress the risks to the minimum, and reduce the resources needed to the minimum, so as to ensure that they can reach the top.

This is like a rich man and a white-collar worker, the rich man focuses on all kinds of big investments, the white-collar workers are busy speculating in stocks, both sides are making money, both have their own financial concepts, and there is nothing wrong with both parties.

Zhang Sen made arrangements for Keiko, naturally considering the overall situation, although the use of the potions of the scientific and technological system would affect Keiko's future cultivation.

But in fact, as long as he creates props to eliminate the sequelae in the future, he may not be able to eliminate the current drawbacks.

So this is the best choice for Keiko in the short term.

At least Keiko can use the ability of genes to greatly increase her own energy, which is actually beneficial to its early cultivation, and when it has sequelae, I am afraid that Zhang Sen has already created props to eliminate sequelae.

After thinking about it clearly, Zhang Sen logged on to the website to find a suitable medicine.

Technology is a thing that is more advanced and more expensive, and the elimination speed is particularly fast, this year's price will be another price next year, and the decline is amazing.

The cost of the medicine is actually very low, mainly because the scientific and technological content in it is valuable, and the more advanced the medicine, the more powerful the effect, and the fewer sequelae.

Of course, there are also some medicines, which are indeed becoming more and more advanced, but the sequelae are also becoming more and more terrible.

Zhang Sen didn't plan to buy the most advanced potion, after all, this thing was only used for Keiko's transition, as long as it could be used, and he had to find a way to eliminate it in the future, so it was not interesting to buy it too expensive.

He flipped through the different potions page by page, looked at the parameters of the potions in detail, and looked for the most suitable potion for Keiko.

Suddenly, he patted his forehead, took out the elf and asked, "Elf, which potion is Keiko's most suitable for?" ”

"XM Phoenix Blood Elixir." The elf replied.

When Zhang Sen got the answer, he unloaded the grinding and killed the donkey, directly threw the elf into the dimensional safe, and then searched for the XM Phoenix Blood Elixir on the search bar, and immediately found the relevant product.

XM Phoenix Blood Elixir is not the latest potion, but an old product from hundreds of years ago, and now it can only be bought in some small stores, because this thing has been discontinued, and the latest Phoenix Blood Elixir has already been updated hundreds of times, and it is completely different from this potion.

The latest Phoenix Blood Elixir not only allows the user to have the ability to resurrect, but also can turn into a phoenix to fight and control the phoenix fire.

Zhang Sen looked at the latest potions of hundreds of abilities, and then looked at the XM Phoenix Blood Elixir, and the more he looked at it, the more shabby he felt that this thing became.

It feels like you're used to playing 3D games now, and if you go back to around 2007 and play 3D games back then, you will feel like the game modeling was rough, the scenes were simple, the characters were stiff, and so on.

Zhang Sen now feels this way when he looks at the XM Phoenix Blood Elixir, but he still decides to believe the elf's answer.

After all, there are often many subtle changes in the body of living beings, even changes at the level of mentality, and small differences in the mental level will cause the same medicine to produce different results in the same body.

Moreover, XM Phoenix Blood Elixir is very cheap, because it is an old product hundreds of years ago, so the price is very low, and it is only sold for 998 Yongyuan in some old stores, compared to the latest product 99998888 Yongyuan, this price is really exciting.

Zhang Sen decisively bought a potion, and then waited for the courier to come to the door.

After all, it is the country of eternity, he just bought the medicine, and the courier came to the door in less than ten minutes, Zhang Sen went out to sign for it, and then returned to his room with the courier box.

Unpacking the package, a red potion appeared in his eyes, this is a blood-red potion, there are many small sparks in the crystal clear potion, the red sparks are like a phoenix flapping its wings, floating in the liquid, looking very beautiful.

Although it is a product of hundreds of years ago, in many worlds it is actually no less than an artifact, if a potion accidentally appears in some low-end world, it may create a protagonist in minutes after being obtained.

XM Phoenix Blood, which can be injected or taken orally, can give people an extremely strong self-healing ability, almost any injury can be recovered in a very short time, and it also has the ability to regenerate.

However, compared to the infinite resurrection ability of the most advanced Phoenix Blood Elixir, XM Phoenix Blood Flask can only be revived once a day, and if you are killed twice by an enemy in the same day, then you will actually die.

After using the elf to determine the authenticity of the potion, Zhang Sen asked the candle spirit to bring Keiko over and give the potion to Keiko to drink.

Keiko finished drinking the potion, and the next moment her body changed, the red light in her abdomen flickered wildly, and then her body turned red, it swayed as if it was drunk, and finally collapsed without the strength of alcohol.

Puff, puff, puff......

Keiko's heartbeat gradually grew louder from the original almost inaudible, and finally even exaggerated to the point of playing a drum.

This sound made Zhang Sen a little worried that his heart would burst out, after all, with such a small body, the heart must be even smaller, but the small heart made such a huge sound, it was terrifying.

Such a loud heartbeat represents the strength of blood circulation, even if Keiko explodes because of high blood pressure at this time, Zhang Sen will not be surprised.

However, what Zhang Sen was worried about did not appear, although Keiko had many abnormalities, she fell asleep and did not have any problems at all.

Gradually, the light of its body began to shrink, and the horn on its head changed from white to red, and then to red again.

It slept for a day and a night, and Zhang Sen also watched from the beginning to the end to surf the Internet, and then did his own thing.

The next day, when Keiko woke up, it was almost noon, and the first thing she said when she opened her eyes was 'I'm so hungry'.

Zhang Sen had already prepared for this, Candle Spirit quickly served a large amount of food, and Keiko directly turned into gluttonous and crazy eating, but the amount of food increased significantly, and the small body was like a bottomless pit.

However, this time the ingredients provided by Zhang Sen are not ordinary ingredients, either Warcraft or Immortal Beast, vegetarian food is either Fairy Grass or Fairy Fruit, the energy is extremely huge, Keiko eats for half an hour.

Then, under the pretext of eating after meals, Zhang Sen directly took Keiko to reappear on Fleet Star, ready to test Keiko's current ability.

Tomorrow is registration day!
