"What’s the solution?" Su Ze’s eyes lit up as he pressed for an answer.

"Let’s sit down and talk." Liou Wenxin pointed to the sofa in the lounge and sat down first, looking as if she were about to launch into a long explanation.

Seeing the eagerness for knowledge written all over Su Ze’s face, she didn’t keep him in suspense and got straight to the point. "There are many methods, not just one.

"Let’s start with the simplest method, though it’s also the most time-consuming. After you finish digesting the Sand Blind Snake Extract, don’t rush to absorb the next vial. Instead, take some time to let your body consolidate. You’ll need to consume high-level Evolutionary Tonics daily and practice the Swan Dance to steadily improve your constitution. The progress will be slow, but it has the advantage of being stable."

Su Ze shook his head as soon as he heard it. ’Too slow. I don’t want to waste that kind of time.’

The fastest way for an Evolver to improve their constitution is through evolution. Each evolution brings a significant boost to their constitution.

The next fastest way is absorbing extracts. Each absorption provides a considerable improvement to one’s constitution, with the magnitude of the boost closely related to the extract’s tier and quality.

Then there’s the process of digesting the extract itself, which also continuously improves constitution. The extracts contain a large amount of Evolutionary Material, and constantly digesting this material promotes rapid constitution enhancement.

The slowest method of all was to rely on taking Evolutionary Tonics.

These tonics also contained Evolutionary Material and could improve constitution after being consumed and digested. However, aside from a few extremely precious natural tonics, even the most effective mass-produced synthetic ones were far less potent than the Evolutionary Material found in extracts.

The Strengthening Elixirs Su Ze had taken before were this type of tonic. Ever since he began seamlessly absorbing and digesting extracts one after another, he hadn’t used them.

This was mainly because he looked down on the tortoise-like speed of improvement.

But in reality, when ordinary Evolvers lacked the required constitution to absorb the next vial of extract, or when they weren’t confident in completing their next evolution, they had to rely on these Evolutionary Tonics to slowly grind and build up their constitution.

Su Ze’s constitution was already exceptionally outstanding. If he were willing to spend several long years slowly consuming tonics to polish his constitution, he might actually be able to absorb a Tier Four extract ahead of his level.

But Su Ze felt it wasn’t worth it, and Liou Wenxin actually thought so too.

So, Liou Wenxin continued to the second method. "This second method is simple and fast: complete your ’Divine Grace of Evolution’ skill."

Upon hearing this, Su Ze immediately shook his head. "Let’s just skip to the third method."

’The complete version of "Divine Grace of Evolution," as a legendary Bloodline Crystal skill and a Divine Skill Prototype, would certainly be a huge help, but talking about it now is unrealistic.’

Even if you gave him ten times the courage, he wouldn’t go to the Mu Country at his current stage.

’Going there would be pure suicide.’

Liou Wenxin nodded. "The third method... well, it will test your luck."

"My luck has always been up to the test."

With his Transmigrator buff, Su Ze had always been very confident in his luck.

Liou Wenxin chuckled. "You remember that your skills can be upgraded, right? Actually, upgrading a skill can also lead to an enhancement of your constitution. This is especially true for your ’Knowledge is Power’ skill. As a skill that strengthens constitution, if you could upgrade it just once, absorbing a Tier Four extract ahead of your level wouldn’t be much of a problem.

"It would even significantly increase your chances of absorbing a Tier Five extract ahead of schedule when you reach the Butterfly Stage in the future!"

Su Ze’s heart pounded with excitement. ’This really is a great method, a great line of thinking.’

’Compared to the other methods, it’s faster and safer. Plus, it would save me time I’d otherwise have to spend at the Saint-level.’

’After all, I’d have to upgrade my skills when I became a Saint-level anyway. Upgrading them now is like getting a head start on what I’ll need to do later.’

"So how do I upgrade my skills?" Su Ze asked.

Liou Wenxin shook her head. "Your ability to upgrade skills isn’t something you can control. That’s why I said it comes down to luck. Based on your past two experiences, your skills only upgrade passively when you encounter evolutionary materials or medicines that are highly compatible with them."

Su Ze had upgraded his skills twice.

The first time was when he drank the Spirit Root Tree Marrow, which upgraded his "Regeneration Body" skill.

The second time was when he touched and absorbed the tentacles of a Tier Four Coral Worm, which upgraded his "Pinprick Strike" skill.

Liou Wenxin continued her analysis. "From this, we can conclude a few things. First, the material that triggers your skill upgrade will always be of a higher tier than the skill itself. And generally, they are high-tier materials around Tier Four."

The Spirit Root Tree Marrow came from a Spirit Root Tree that was Tier Four, bordering on Tier Five. The Coral Worm Tentacles also came from a Tier Four Coral Worm.

Therefore, if Su Ze wanted to passively trigger a skill upgrade, he would most likely need materials of that tier.

Su Ze recalled, "When I saw the Coral Worm Tentacles, I felt a strong physical instinct to touch them. This suggests that my body can sense when I’m near materials that can upgrade my skills.

"The strange thing is, I didn’t get that same instinctive feeling when I first saw the Tree Marrow."

Liou Wenxin agreed with this point and said, "When you encountered the Tree Marrow, you were only in the Pupa Stage. It’s possible that this sensory ability improves along with your evolutionary level."

Su Ze nodded. "If there isn’t a fourth method, then this third one is probably the most suitable for me. What I need to do next is collect materials that might trigger my skill upgrades."
