Lin Yuan looked carefully at the twenty spiritual crystals, each as big as half a thumb, in the small bluestone bowl in the soul-locking space and could not help but admire them.

These spiritual crystals, which are half the size of a thumb, have a very crystal clear texture.

There seemed to be some vaguely invisible gas flowing inside, and when light shone on it, it emitted a faint rainbow color.

But if you don't look closely, these twenty spiritual crystals really look like some irregular broken glass crystals.

However, the value of the spiritual crystal is far beyond that of those irregular broken glass crystals.

Lin Yuan smacked his lips as he looked at these twenty spiritual crystals.

These twenty spiritual crystals would not have been created if it weren't for the tiny bit of grace from heaven and earth that fell on Mobius's Pure Land when the Mother of Bloodbath reached the second level of mythology.

Instead, it was based on Mobius's skill that the spiritual energy condensed itself into a form, which would take at least more than one hundred and forty days.

The premise for these one hundred and forty days is that there is an adequate supply of energy minerals.

These spiritual crystal forest hikes can elevate any of one's three fantasy creatures to the level of gold-level fantasy transformation.

These twenty spiritual crystals can immediately bring about a qualitative change in Lin Yuan's strength after use.

However, Lin Yuan still needs to consider carefully which one of Lily Lily, Yinyin and Yuansha should be upgraded to the level of golden fantasy species first.

Because no matter which one is upgraded, it is destined to become Lin Yuan's trump card.

Even Lin Yuan's fighting style had to change in favor of the spiritual object or source item that had been upgraded to a gold-level fantasy species.

Especially after Lin Yuan knew that the strength of the Huiyao Hundred Sons Sequence was not as simple as it appeared, Lin Yuan developed a great sense of urgency.

Since Lin Yuan has already decided to participate in the competition for the Brilliant Hundred Sons Sequence this year, he naturally will not back down.

So what Lin Yuan needs to do is to improve his strength as soon as possible.

And these twenty unexpectedly obtained spiritual crystals were enough for Lin Yuan to immediately obtain a trump card at this moment.

Lin Yuan thought that if the situation remained the same, by the time he participated in the selection for the Hundred Shining Sons sequence, he would most likely be able to raise the levels of the two fantasy creatures to the gold rank.

It can even raise the level of the Acid Bee Queen from the first level of the Gold Rank.

A first-level gold fantasy creature already has the combat power of a platinum level.

Platinum-level combat capability is the most basic strength standard for those who want to be shortlisted for the Brilliant Hundred Sons Sequence.

After some choice, Lin Yuan directly gave up the Lily Lily who was a first-level silver rank fantasy.

Increasing Lily Lily's level will only enhance Lin Yuan's healing ability.

Although healing spiritual professionals are very rare and highly sought after, Lily Lily's advancement to a gold-level fantasy spirit creature can also greatly increase Lin Yuan's healing ability.

However, the improvement in healing ability did not provide any substantial help to Lin Yuan in his competition for the Hundred Shining Sons.

So Lin Yuan now has to make a choice between Yinyin and Yuansha.

After thinking for a moment, Lin Yuan gave up the plan to improve Yin Yin first and promote her from the silver level one fantasy transformation to the gold level one fantasy transformation.

Although Yinyin is Lin Yuan's strongest force at present, even after Yinyin is promoted to a gold-level fantasy species, she can use her brilliant body to kill a platinum-level spiritual creature in one blow.

However, although this ability is highly lethal, its tolerance rate is extremely low.

If Yin Yin fails to decide the outcome of the battle while using her Brilliant Body, then Lin Yuan will most likely face failure.

Furthermore, the Acid-Corroded Queen Bee of gold-level first-class legendary quality can, to some extent, play the same role as Yin Yin.

Acid Queen Bee and Yin Yin are both high-burst single-target damage units.

But this gold-level skill is not something Lin Yuan can decide.

Yinyin is currently only at the first silver rank, and her combat system has not yet been fully determined.

Gold, platinum and even diamond level skills are still an unknown to Yinyin.

Therefore, for Yinyin, the improvement gained by upgrading her rank is a big uncertainty factor.

Although Yinyin will only become stronger and stronger, Lin Yuan feels that the comprehensive source sand is more suitable for improving his overall strength.

No matter how strong Yin Yin becomes, her attack is the only aspect that is strengthened.

However, although Yuansha's improvement in attack is no way half of Yinyin's, Yuansha pays more attention to defense and control.

After finishing the first ladder promotion match with Cheng Hongfeng, Lin Yuan realized the importance of increasing self-protection capabilities in battle.

And after the second ladder promotion match with Du Meimei.

There is no wrong version in the 1619 book forum!

However, Lin Yuan attached more importance to the ability to protect himself, and even felt that for spiritual professionals, self-protection was the most important factor.

If Du Meimei had the ability to protect herself at that time, she would have been able to survive Yin Yin's fatal blow.

Then it would be impossible for Lin Yuan to defeat Du Meimei.

Although Source Sand is comprehensive, it is still just a source creature that has undergone a fantasy transformation at the Bronze Level 10.

Although it has great potential, it is still too weak in terms of strength.

But what Lin Yuan has to do now is to enhance the level of the source item source sand.

Allow Yuansha to be promoted from the bronze level ten fantasy transformation to the gold level one fantasy transformation.

Now that he had made the decision, Lin Yuan no longer hesitated.

He picked up the small bluestone bowl, and then turned the amber crystal button-shaped source sand that had been hanging on his sleeve into a pile of yellow sand.

Then Lin Yuan picked up a spiritual crystal and threw it into the pile of yellow sand.

The yellow sand immediately formed a high-speed vortex with the spiritual crystal as the center, rapidly absorbing the energy in the spiritual crystal.

Source Sand is the most special existence among all the spiritual creatures and source creatures contracted by Lin Yuan.

No matter how high the level of Source Sand is, it will not add any skills or exclusive features.

Therefore, Lin Yuan estimated that after the source sand’s level was upgraded to the gold level, it should enhance its existing exclusive characteristics.

Soon, the huge energy in the spiritual crystal was completely absorbed by the source sand that had transformed into the Bronze Level 10 Fantasy.

The level of Source Sand also increased from Bronze Level 10 Fantasy Transformation to Silver Level 1 Fantasy Transformation.

The source sand that had turned into an amber button shape again did not have any obvious changes compared to its previous appearance. Instead, it became more restrained and less noticeable.

At this time, Lin Yuan's source item source sand was upgraded from the bronze level ten fantasy transformation to the silver level one fantasy transformation.

I immediately felt that the restrained amber button-shaped source sand was shaking slightly, and it sent a very vague spiritual request to me cautiously and kindly.

The first update~There will be three more updates later, today's double update plus tomorrow's first update~a total of four updates.
