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

[Deploy the Originium using 2000 Cubic Coins?]

"It's really expensive, yes."

Fortunately, Leon Lai has money on hand now.

hum…

The phantom solidified, and a brand new cubestone appeared next to the wooden house.

Its appearance is quite different from other cubic stones; it is flat and round overall, with two sloping slots on the top.

A small 3D image floats above the card slot; it is a ball of light that constantly changes shape, as if waiting for some command.

"Let's try it first."

He immediately pulled out two [Level 1 City Wall] cards.

Level 1 city walls are relatively common drops, so he accumulated quite a few.

Place the two cards together and insert them into the slot of the Originium.

The synthetic stone trembled slightly, and a line of text appeared on its surface.

[Two level 1 walls have been detected; they can be combined to create a level 2 wall.]

[Do you want to spend 100 cubic coins to synthesize this card?]

"It's not expensive, so it's fine."

A flash of light, and the two level 1 wall cards melted into liquid, then reformed into a new card.

The cards have a noticeably heavier feel.

Two Level 1 walls of the same length can be combined into one.

He quickly made a mental estimate.

If we reclaim all the existing level 1 city walls in the territory and then concentrate all the resources...

It should be able to synthesize enough [Level 2 city walls] to completely replace the existing city walls.

Even disregarding those three options, the [Level 2 city wall] itself has a higher basic sturdiness.

However, there is a problem.

"I wonder if the special effects during the city wall upgrade will be lost..."

My T-shaped entrance was upgraded to a Level 2 wall last time, so I have experience.

Li Ming took out a 1-meter-long [Level 2 City Wall] to test it out first.

[Deploy this section of the wall using 100 cubic coins?]

"Yes."

The section of the wall you deployed is at level 2.

Please choose one of the following effects.

[1. Durability +50%.]

[2. Height increased to 3 meters.]

3. Wall cleanliness +50%.

Fortunately, even if we choose direct deployment instead of upgrading, we still have options.

He breathed a sigh of relief and looked at option 3.

This thing is a bit of a gimmick; keeping the wall clean just means less moss and weeds will grow, but it doesn't have much practical use.

So I still chose option 1.

If the walls are recycled and rebuilt into level 2 walls and redeployed, will those special effects still be there?

After deploying it, he removed that section of the wall and redeployed it.

The section of the wall you deployed is at level 2.

The previous effect has been automatically selected during the deployment process.

"As expected, you can't rely on repeatedly grinding to exploit bugs and get special effects."

He was a little disappointed, but not too disappointed.

This tool is designed to be a convenient batch upgrade tool, so it's impossible to leave that much room for manipulation.

He then tried merging the walls with the two selected special effects together.

The attempt failed, and a message popped up.

[Unable to merge: The visual effects of the two sections of the city wall are inconsistent.]

The walls can only be merged if the two sections of the wall have the same special effects.

After thinking about it, he finally decided to honestly assign all the city walls a +50 increase in fortification.

After replacing all the city walls, he turned his attention back to the synthetic stones.

Synthesizing the wall card was just a small test; what he really wanted to synthesize were other cards.

The cards dropped by the giant skeleton hand are far more than these.

Dawn also pulled out two items that gave him a slight headache: [Level 1 Upgrade Card (Breaking Momentum)] and [Level 1 Upgrade Card (Steadfastness)].

Both are the most common upgrade cards for going from Tier 1 to Tier 2, and they can fetch a good price if sold outside.

The problem is that all his Heroic Spirits are now at least Tier 2.

The Tier 1 upgrade card is useless to him.

"Thank goodness we have the Synthetic Stone."

He inserted the two Level 1 upgrade cards into the left and right card slots respectively.

The surface of the synthetic stone immediately began to shimmer, and a line of text appeared.

【检测到1级升阶卡（破势）x1，1级升阶卡（坚定）x1，可合成为2级升阶卡（随机）。】

[Do you want to spend 1000 cubic coins to synthesize this card?]

Although the cost of synthesizing 1000 cubic coins is not cheap, it is completely affordable for him now.

"synthesis."

hum!

Two beams of light surged out of the slot simultaneously, and a few seconds later the two colors of light suddenly merged together.

As the light faded, a brand new card lay quietly in the Originium's drop slot.

[Tier 2 Upgrade Card (Breakthrough)]

"Great!"

As dawn picked up the card, a smile involuntarily crept onto his lips.

The Breakthrough System is exactly what he needs right now.

Currently, the only two heroes in the team with the "Broken" type are Guan Yu and Lu Bu. Guan Yu is already at Tier 3, so it can only be Lu Bu.

He had witnessed firsthand Lu Bu's terrifying performance with true damage against high-armor bosses in the battle just now, and had already decided that if he had the chance, he would prioritize upgrading Lu Bu to Tier 3.

However, before advancing to the next level, let's take care of something else first.

He took out the [Level 1 Trait Enhancement Card] he had obtained when leveling up as a Summoner.

Your Heroic Spirit has received a trait enhancement.

【Assault - Trait☆】: When dealing 100% armor penetration damage, all attributes increase by 20% for 3 seconds (from 10% to 20%).

Even if other Servants receive a single stat boost of +30%, the total stat gain may not be as good as this +20% to all stats.

Moreover, Lu Bu himself is the hero with the highest total attribute value in the team, and the higher the base value, the higher the absolute value of the bonus.

With the 20% bonus to all attributes from the [Valiant] enchantment within the territory, plus the 20% bonus to all attributes after the [Flying General] skill is activated, and the 20% bonus after enhancement, Lu Bu's total attributes soar to 160% when all three are combined.

Even though Guan Yu is also at the third tier, his total attribute value will be lower than his.

"Next, advance to the next level."

He pressed the [Level 2 Upgrade Card (Broken Force)] onto Lu Bu's card.

[Do you wish to use 2000 Cubic Coins and an Upgrade Card to upgrade this Servant?]

"Yes."

boom!

A crimson-black light shot into the sky from the card representing Lü Bu, even more ferocious and arrogant than the Azure Dragon phantom when Guan Yu ascended to the third rank.

Lu Bu has advanced to Tier 3.

The Heroic Spirit's attributes have been improved.

"panel!"

[Lu Bu]: Tier 3, LV5, Breaking Force

【Assault - Trait☆】: When dealing 100% armor penetration damage, all attributes increase by 20% for 3 seconds.

[Peerless - Passive]: Lu Bu's melee damage is all true damage.

[Shooting Halberd - Passive]: Lü Bu gains ranged attack ability.

[Flying General - 100% Energy]: Lu Bu's all attributes increase by 20% for 30 seconds. Consuming energy during this period can extend the duration.

"Shoot the halberd!"

Shooting the halberd at the gate is one of the most legendary stories in Lü Bu's life.

He shot an arrow into the small branch of the halberd, defusing a major battle with his superb archery skills.

This entry grants him the ability to attack from a distance.

For Lü Bu, ranged attacks are extremely important.

The first issue is energy accumulation.

The Breakthrough type gains energy by dealing damage, and ranged attacks allow you to deal damage and accumulate energy before enemies even get close.
