Immortality!

Even without counting the exceptional case of Gu Xun'er, there were other female characters with excellent cultivation talent.

There would be no problem for them to become Battle Saints. Then, as the children of Battle Saints, no matter how poor their talent was, they should still be able to reach Peak Dou Zun, right?

After all, the connections of a Battle Saint were right there.

Even if they could not have children together, he could still make an investment and earn a favor. Their own value was also immense.

What did a favor from a Battle Saint mean? That hardly needed explaining.

Compared to them, Ya Fei seemed somewhat...

It was only natural that she had little screen time.

Wu Yan shook his head almost imperceptibly. He had little interest in things like conquering these female characters in this life.

He had lived for more than seventy years in his previous life. It was not as though he had never slept with women; he was not that desperate.

Having fully experienced birth, aging, illness, and death, Wu Yan had made immortality the ultimate goal of this life.

Before immortality, everything else had to make way.

No matter how beautiful a woman was, no matter how many halos she possessed, even if the child she bore was guaranteed an IQ of one hundred and eighty, she would ultimately be nothing more than a pretty skeleton.

In Wu Yan's view, children were a continuation of their parents' lives. Since those parents could not live forever, they could only pass down and continue their biological information through having children.

But what if those parents could achieve eternal youth and immortality?

At that point, would there still be any need to have children?

Under Luo Su's guidance as a "tour guide," Wu Yan spent a day gaining a general understanding of Mittel City. At the very least, he would no longer get lost.

The day off passed quickly. With the support of another two first-tier wood-attribute Magic Cores, Wu Yan soon returned to his usual diligent cultivation.

However, there was one additional change. In the days that followed, Ya Fei, still a little girl, appeared often.

Wu Yan could understand Luo Su's intentions without even thinking about it. It was nothing more than the usual tactic of investing in advance...

Wu Yan did not care about that.

As long as these schemes did not affect his own cultivation, anything was fine.

Moreover, with little Ya Fei around, when Luo Su began teaching Wu Yan spear techniques a month later, he was clearly far more serious than before.

After realizing Ya Fei's usefulness, Wu Yan, who had never cared much to begin with, gradually grew accustomed to her presence.

And so, Wu Yan truly set foot upon the path of spear training.

Days passed one after another. In the fifth month after Wu Yan broke through to the Seven-Star Dou Practitioner realm and truly began learning the spear,

and also the ninth month after the year-end assessment, Wu Yan reached the end of the Dou Practitioner realm. His breakthrough to Dou Shi went exceptionally smoothly, as naturally as water flowing into a channel.

After the breakthrough, Wu Yan carefully sensed his current strength. Even without using dou qi to enhance himself, a casual wave of his hand could unleash tremendous power.

If he used dou qi to enhance himself, it would be even more terrifying.

Wu Yan secretly estimated that he should now be able to pull a stationary cart.

And this was only the Dou Shi realm. How powerful would he become after breaking through to Da Dou Shi, Dou Spirit, and even Dou King, reaching the realm where one truly began to transcend the mundane?

With those thoughts in mind, Wu Yan's desire to pursue immortality grew even stronger.

After regaining his usual calmness, Wu Yan glanced at his lower abdomen, at the small lake where two colors had perfectly fused together.

He was slightly surprised. He had not expected his dou qi reserves to be so astonishing after breaking through to Dou Shi.

But upon further thought, he cultivated a High Profound Tier technique. Since he possessed ice-and-water dual-element dou qi from the same source, that amount had to be doubled on top of it.

With that in mind, it was perfectly normal for him to possess such vast dou qi reserves.

After briefly adapting to the strength he had gained from breaking through to Dou Shi, Wu Yan left home.

He did not rush to cultivate. He had pushed himself too hard recently, and remaining constantly wound tight was not a good thing.

When Luo Su learned that Wu Yan had taken leave in order to break through to Dou Shi, he directly gave him a week off.

In his view, the boy had reached Dou Shi at only twelve years old. He had plenty of time ahead of him, so there was no need to rush.

Most teachers demanded that students follow strict standards because most students lacked strong self-discipline and were always thinking of ways to slack off.

But if a student cultivated day and night and worked exceptionally hard, then a teacher had to let that student relax a little.

Of the week-long break, Wu Yan had spent two days on his breakthrough, leaving five days.

Over the next few days, Wu Yan planned to test the effects of Energy Liquids produced by the Little Blue Bottle from several other common attribute Magic Cores.

Having broken through to Dou Shi, Wu Yan had gained a little more confidence in himself and dared to give it a try.

Using the remaining half of the day, Wu Yan strolled around Mittel City with a leisurely, relaxed appearance.

While buying small gifts for his family, Wu Yan did not forget the primary purpose of this outing.

Gold, wood, water, fire, earth, wind, lightning, and ice.

Wu Yan bought one first-tier Magic Core of each of the eight common attributes.

Aside from the relatively rare wind, lightning, and ice attributes, which cost one thousand gold coins each, he acquired the other Magic Cores for only five hundred gold coins apiece.

Besides that, Wu Yan also bought one hundred small jade bottles with excellent seals to store the Energy Liquid.

After giving the gifts to his mother, Wu Yan returned to his room and began his tests.

After thinking for a moment, Wu Yan decided to test a water-attribute Magic Core first.

The reason was simple. Water and wood attributes were both extremely gentle. He had already been able to consume Wood-Attribute Effect Energy Liquid for cultivation, and now that he had broken through to Dou Shi, consuming Water-Attribute Effect Energy Liquid would almost certainly pose no problem.

The Little Blue Bottle within Wu Yan's soul still looked the same, with no obvious changes. If he had to name one, its color had become brighter and more translucent.

However, the change in color was not very obvious. If the Little Blue Bottle had not been inside Wu Yan's soul, he would not have noticed it at all.

At Wu Yan's command, the water-attribute Magic Core on the table was absorbed into the Little Blue Bottle.

Two breaths later, Wu Yan received feedback from the Little Blue Bottle.

"Instant refinement?"

Wu Yan was somewhat surprised. He had not expected the Little Blue Bottle's speed in refining first-tier Magic Cores to improve so drastically after his breakthrough.

It had previously taken several minutes to complete the refinement, but now it needed only a few seconds. That was an improvement of dozens of times!

Surprised though he was, Wu Yan did not forget his purpose.

He mixed a drop of deep-blue Energy Liquid with boiled water and swallowed it. Wu Yan immediately turned his awareness inward. He wanted to see for himself what effect this Water-Attribute Effect Energy Liquid had.
