What the Dark Demon Flame Ray collided with was the city defense-level energy shield rune array that Bai Yuqi had personally arranged in Ember City.

This energy-shrouded defensive runic array was inspired by the Battle of Pyongyang Fortress in Goguryeo.

At that time, the Goguryeo Witch King used the [Plane Hub] of the negative energy half-plane, which is the energy supplied by the meteorite core.

Opened a negative energy shield that enveloped the entire city of Pyongyang, and its strength was even able to resist the [Super Explosive Magic Guided Missile] released by Bai Yuqi.

Afterwards, he obtained this [Plane Hub] as a trophy of the Tai Sui Vortex, and after returning to the arcane laboratory of the Flame Tower of the Burning City of Yingzhou, he conducted in-depth research and development on it.

Based on the principle of this "Dimensional Hub Energy Shield", several large-scale protective spells have been developed.

While these improved large-scale protection spells may not have the same defensive power as the [Plane Shield] powered directly by the [Plane Hub], they can be used for city-level defense in a variety of situations.

Among them, there is the "Natural Element Crystal" produced by the leylines of Zhongnan Mountain, and the various levels of [Spirit Stone Shield] magic circles that are the core of the rune array.

This easy-to-carry [Spirit Stone Shield] can be flexibly used in various places because it can automatically absorb elemental energy from nature to recharge.

For example, the Micro Individual Energy Shield, the Small Vehicle Energy Shield, the Medium Building Energy Shield, the Large Village-level Regional Energy Shield, the Giant Town-level Regional Energy Shield, and the Super Giant City-level Energy Shield...... Wait a minute.

The size of the defense range and the strength of the defense depend on the size of the "Natural Elemental Crystal" that is the core of the [Spirit Stone Shield] rune array.

Although there are also more advanced [Spirit Crystal Shield], [Arcanic Crystal Shield], [Burning Crystal Shield] and so on.

However, they are all based on the same principle of the rune array, and the energy core contains different versions of the energy level, and the popularity and applicability are not as high as those of the [Spirit Stone Shield].

The top one is, of course, the [Plane Hub Shield], but unfortunately Bai Yuqi only has one [Negative Energy Half-Plane Hub Core] in their hands at present, and the negative energy is invasive to living beings, so it is temporarily sealed.

In addition, Bai Yuqi and Tai Sui Vortex are also working on a shield that does not require energy core energy, but can stimulate an energy shield, tentatively named "Faith Shield", the principle of which is to use the "power of faith" of town residents to induce.

Once the research is successful, Bai Yuqi may be able to make a few artifacts similar to "Zhenguo Ding" for Datang.

As long as there are more inhabitants in the town and the stronger the power of faith, the stronger the defense and the greater the protection range of the [Faith Shield].

At that time, as long as the inhabitants of the town are not killed and the power of faith is not exhausted, the [Faith Shield] will never be breached, and it is an excellent defensive measure.

What Bai Yuqi used on the Ash City was the city-level [Spirit Stone Shield].

However, because the Havoc Plane does not have any natural elemental energy for the energy core to draw on.

Relying solely on the energy contained in the energy core itself, it will not take long to completely destroy the core.

Therefore, Bai Yuqi had to think of a way from the energy of the catastrophic plane itself.

Due to the dark sun and remnant sun of the Havoc Plane, the dark energy radiation emitted was too violent to control.

Therefore, in order to research the [Dark Energy Shield], it took Bai Yuqi a lot of energy.

The main thing is that there is no core that can be used as a "container" to contain the dark energy that the rune circle automatically absorbs.

In order to solve this problem, Bai Yuqi even took the initiative to absorb some dark energy to conduct the experiment, which was very hard.

Although he was able to survive in the cataclysm plane, it was because he relied on the phlogiston energy of phlogiston crystals in his body to protect himself and isolate the invasion of dark energy.

So when he took the initiative to let go of his own protection and absorb the violent dark energy that was flooded in the space of the catastrophic plane, he almost didn't play himself to death.

After all, he has not evolved in the Havoc Plane for thousands of years, and his gene cells have adapted to the native creatures where dark energy exists, so that after absorbing dark energy into his body, he has been seriously damaged with the strength of his body.

Fortunately, this unscientific body has perfect regenerative ability and super extreme environmental adaptability, and has already started a super-high-speed self-evolution while being damaged by dark energy.

After the gene cells were burned and died by dark energy, they regenerated at a high speed, and after almost replacing Bai Yuqi's entire person several times, they finally perfectly adapted to the existence of dark energy, and they are still slowly optimizing the cell's ability to accommodate dark energy.

Unlike those native creatures who also need the "Source of Life" to alleviate the damage of dark energy, Bai Yuqi's current state is the perfect form that truly adapts to dark energy.

Dark energy will no longer cause damage to his cells, but will continue to strengthen his cells, promoting the continuous evolution of his life state.

Bai Yuqi didn't know if this change was good or bad, but judging from the body's reaction, it didn't seem to be affected much, so he simply ignored it.

Anyway, Bai Yuqi has long suspected that he is not actually a "human", but some kind of "alien" descendant who has been exiled to Earth, like a Kryptonian like Superman Clark Kent.

Otherwise, it is completely impossible to explain his unscientific body strength, unscientific evolution speed, and the unscientific Wolverine claw blade in his arm.

So it's not a "person" anyway, and Bai Yuqi doesn't care about the existence of another kind of dark energy in his body.

After evolving to a state of perfect adaptation to dark energy, Bai Yuqi began to try to take the initiative to absorb the violent dark energy that was flooded in the space of the Havoc Plane.

Just as it can actively absorb the free arcane particles in space, [Meditation] can also absorb the dark energy in the space of the Havoc plane.

Through several promotions, Bai Yuqi not only evolved his original [Arcane Physique] into [Arcanic Physique], and then evolved into [Arcanic Fire Spirit].

He also evolved the original [Arcane Fire Source] into [Arcane Crystal Seed], and after evolving into a [Arcane Crystal Source Seed], he even had a [Phlogiston Body].

In this state, he was already able to perfectly control all kinds of energy in his body, so he imitated the [Ao Jing Source Seed] after condensing a ball of [Dark Energy Seed] in his body.

Finally, through the improved [Dark Energy Meditation], he was able to frantically absorb the dark energy of the Havoc Plane and condense a "Dark Energy Crystallization Seed", which was used as the core of the [Dark Energy Shield] rune circle and applied to Ashen City.

And because this "Dark Energy Crystalline Seed" was born from the [Dark Energy Seed] in Bai Yuqi's body, it also has a biological evolutionary ability!
