I summon the heroic spirits of China in the infinite world.

Dawn stacked the five cards together and pressed them onto the surface of the main cube.

[Use 5 Cube Upgrade Cards to upgrade the main cube to LV5?]

"Yes."

With a hum, the blue light on the surface of the main cube became even more intense, and a visible halo spread out from the bottom of the stone, covering the entire territory.

Your main cube has been upgraded to LV5.

Please choose one of the following effects.

[1. Increase the radiation area by 25 square meters.]

2. Slightly weakens monsters within the area.

[3. Randomly obtain one permanent effect, with a small chance of obtaining a rare effect.]

Looking at the three options, Li Ming didn't hesitate at all and chose option 3.

[Random options loading...]

You have gained a permanent effect: Invincibility Mode.

You can set a condition that prevents heroic spirits within your territory from harming each other.

"This effect..."

Li Ming was taken aback at first, then his eyes lit up.

He really wanted this feature.

Especially after Zhao Yun and Huang Zhong's AOE abilities were developed.

Prior to this, he had been careful to avoid accidental injury.

For example, the most obvious example is Lu Bu and other heroic spirits.

From the very beginning with Liu Bei, Guan Yu, and Zhang Fei, he noticed that there seemed to be a certain tacit understanding among the Shu generals.

But Lü Bu did not; he did not cooperate well with the Shu generals.

Especially when space is limited, it's either people squeezing each other or weapons clashing.

After all, apart from Liu Bei, the other heroic spirits all wield polearms, which require sufficient space to unleash their power.

Although it may not be a big deal most of the time, it can still have some impact over time.

That's why, when arranging the defenses, he placed the immobile stone monkey and the ranged attackers Zhuge Liang and Lü Bu in the same spot.

"The most crucial thing is that this function can be set according to my will, can be adjusted at any time, and can also be set to one-way non-damage when selecting a target."

"If this function had been available when Lu Bu was bewitched the night before, I could have directly set Lu Bu to be invincible against friendly forces, and then friendly forces could injure Lu Bu."

"Unfortunately, this function can only be used within the territory and cannot be used outside."

Dawn was slightly disappointed.

With the no-damage mode set up, he turned his attention to the thick stack of cards.

The rewards for the tenth night milestone are indeed generous. If all these resources were converted into combat power, the overall strength of my team could be raised to at least another level.

"One at a time."

He first picked up the three Level 1 Huaxia Upgrade Cards.

The Huaxia Upgrade Card is universal and does not distinguish between the seven elements; it can be used by any Huaxia Heroic Spirit.

However, he currently only has two Tier 1 Heroic Spirits left under his command: the Stone Monkey and Zhuge Liang.

Therefore, two cards were directly assigned to the Stone Monkey and Zhuge Liang, and the remaining card was saved for later.

Let's start with Zhuge Liang.

Li Ming took out his first Level 1 Huaxia Upgrade Card and chose Zhuge Liang.

[Do you wish to use 500 Cubic Coins and an Upgrade Card to upgrade this Servant?]

"Yes."

Pale blue fragments of light enveloped Zhuge Liang like a thin layer of mist.

Zhuge Liang has been promoted to the second rank.

The Heroic Spirit's attributes have been improved.

"panel."

[Zhuge Liang]: Tier 2, LV4, Wise

[Cleverness - Trait]: Active skill effect +10%

[Empty City - Passive]: When Zhuge Liang's energy is 0, he cannot be selected as a target.

[Eight Trigrams Formation - Passive]: Zhuge Liang can grant any one of the eight heroic spirits within a 20-meter radius a +10% bonus to any single attribute.

"This passive skill..."

As dawn broke, he carefully examined the newly appeared entries, his eyes gradually brightening.

The origin of the term "empty city" is self-evident; it refers to one of Zhuge Liang's most famous psychological maneuvers in history.

On the western city wall, the city gates were wide open, and Kongming played the zither alone, frightening away Sima Yi's 150,000-strong army.

Now, in this instanced world, this term has reappeared in another form.

The energy mechanism of the Wisdom type is different from that of other types.

Other types of Heroic Spirits have more or less means of recharging themselves, but the Wise type is completely unable to regenerate energy on their own.

The term "empty city" takes full advantage of the flaws in the "wise" system.

Once Zhuge Liang's energy is depleted, he will enter an empty city state, becoming untargetable by enemy attacks or skills.

This means that as long as he uses [Blessing] to deplete his energy, he can safely stay there and act as a buff machine.

With the [Eight Trigrams Formation] providing attribute bonuses to the entire team, there's no need to worry about being focused down and killed by the enemy.

It can also deal some wind blade damage, so it's good to be a low-damage dealer who doesn't need to worry about safety.

"Perfect for a prime minister."

Li Ming nodded in satisfaction.

He had witnessed firsthand how fragile Zhuge Liang's body was far too often.

When fighting the Dream Eater leader, the BOSS simply flicked its nose and instantly killed him from full health.

With the empty city, at least the situation of being targeted by the BOSS and dying instantly will no longer occur.

However, a question suddenly occurred to him.

"It seems like Liu Bei is somewhat of a nemesis to Zhuge Liang..."

Liu Bei's "Winning People Over with Virtue" aura restores 0.3% energy to allied heroes within its range every second.

As long as Zhuge Liang stood next to Liu Bei, his energy would be constantly replenished.

You can never go back to zero, and you can never trigger the empty city.

"It's alright, just be more careful about where you stand next time."

He then activated the simulation stone.

A phantom image of Zhuge Liang appeared on the sand table of the simulation stone, and its energy was set to 0, triggering the [Empty City] state.

The test results are clear: in the "Empty City" state, enemies cannot actively target Zhuge Liang; neither single-target attacks nor single-target skills can lock onto him.

However, if the enemy releases an AOE attack, the [Empty City] state will not provide immunity.

Friendly fire AOE attacks can also affect you, but you can just set it to a no-damage mode.

"That's all there is to it. The ability to survive has been greatly improved, which is good."

Overall, Dawn was satisfied with his promotion.

Next up is the stone monkey.

[Do you wish to use 500 Cubic Coins and an Upgrade Card to upgrade this Servant?]

"Yes."

Golden shards of light surged forth, coating the rough stone surface layer by layer.

As the light penetrates the surface of the stone, its color gradually takes on a metallic texture.

The stone monkey has advanced to the second tier.

The Heroic Spirit's attributes have been improved.

"Let's see what the new entry is."

[Stone Monkey]: Tier 2, LV3, Steadfast

【Accumulated Strength - Trait】: When the Stone Monkey has been attacked a total of 10 times, it immediately launches an attack.

[Stubborn Stone - Passive]: The stone monkey takes 20% less damage.

[Celestial Embryo - Passive]: Stone Monkey's maximum health +20%

"Simple and unpretentious, nothing much to say."

Li Ming looked at the entry and nodded.

Both damage reduction and increased health are survival and defense-oriented attributes.

He can be considered a competent and steadfast Heroic Spirit, but he is still far from the Great Sage he imagined.

I don't know when I will be able to transform into a saint.
