Wizard: I brought the wrong system.

Chapter 402 Resource Direction
Once this wisp of 'life force' entered the heart along a specific route, the heart, which was already beating vigorously under the influence of anger, was stimulated and beat even more violently.

Emotions affect the body, and the body also affects emotions.

As his heart pounded, Yaro felt as if his blood was boiling. The hateful face in his memory became clearer and clearer. The anger that had only been deliberately provoked was as if it had been doused with hot oil.

The veins on his brows bulged involuntarily, as if an invisible valve had been closed, and power began to surge forth continuously.

Explained using past-life biology:
A person's strength is generally determined by the excitability of the nerves that control the muscles. When angry, the nerves are excited, so when emotions are intense, strength is greater than usual.

According to Aro's own understanding:
The human body is a sophisticated yet fragile machine. Under normal circumstances, whether actively driven by reason or passively driven by subconsciousness, the goal is to survive for a longer period, that is, to avoid harming the body. However, in a state of anger, the body shuts down some of its limitations, thereby unleashing a much greater amount of power.

Of course, the above only conforms to part of the basic principles of the secret technique "Blood Rage".

Because the influx of 'vitality' causes minor damage to the heart muscle, proteins fill the wounds, and the remaining 'vitality' also fills in during this process, strengthening the heart muscle while also activating the entire heart.

Once the heart is fully activated, it is no longer just a simple reservoir of 'vitality'; it can also activate the blood, that is, transmit vitality into the blood.

Then, by utilizing the process of unlocking the body's potential, the 'life force' accumulated in the heart is directed throughout the body, quickly delivered to every tissue and organ related to the power burst, thereby unleashing power beyond the limits!

Based on this principle, the name "Blood Frenzy" is indeed very appropriate.

"Hmm... the future is bright, but reality is cruel!"

Yaro grimaced and clutched his chest, gasping for breath.

Unlike the muscles in other parts of the body, even mild soreness in the heart can be terrifying.

It's like walking a tightrope alone on a bottomless abyss, isolated and helpless, with your life hanging by a thread.

After catching his breath, Yaro gritted his teeth and continued.

This is a struggle between reason and survival instinct, much like the fear of crashing into trees he faced when learning to climb them as a child.

However, Yaro was no longer the child he once was, and his control over his body was extraordinary. He suppressed his instincts with reason, and only when the energy gradient in his body was almost the same and the 'life force' stopped flowing into his heart, did he consider today's training complete.

The original book, "Qi and Blood Frenzy," states that one can only practice this secret technique once a day, and must not engage in strenuous exercise the following day to allow the heart to fully recover.

This process needs to be maintained continuously for more than ninety days.

—For ordinary people, even just heart muscle damage can take three to six months to recover from, but mastering this secret technique only takes ninety days, and it still has 'vitality' to enhance the recovery speed.

Yaro sighed inwardly, "Ninety days, and the gap in the white downy hairs is a bit too big."

If the white velvet wasn't eaten during the training, and if some of the white velvet wasn't given to the lab mice, then almost all the roots of a tree spirit would be enough to successfully cultivate "Blood Frenzy".

But Yaro did not regret it.

Being vigilant when traveling is never a bad thing.

"We wasted too much in the past. The remaining amount is only enough for about twenty days at most, and we are still short of nearly seventy days' worth... The gap is too big, and it is impossible to get it all from the tree demon."

While trying to calm his anger by thinking about other things, Yaro slowly submerged himself into the bathtub, which had been prepared with hot water.

After strenuous exercise, people usually apply ice. This is because when the body senses cold, blood vessels automatically constrict, thereby reducing blood flow and reducing muscle swelling.

Once the condition improves slightly, hot compresses will be applied to accelerate blood circulation and help the wound heal as quickly as possible.

The principle behind hot baths in Yaro is the same. During a hot bath, blood vessels throughout the body dilate, causing more blood to flow into the vessels. This drains excess 'vital energy' and reduces the amount of blood remaining in the heart, making it less likely for minor injuries to swell.

In short, although Yaro is currently undergoing a 'heat bath,' it is actually having the effect of a 'cold compress.'

"call……"

The decrease in heart and blood pressure significantly alleviated the pain, and Yaro breathed a sigh of relief, lounging lazily in the bathtub.

"Dark Plains... You can tell from the name that it's not a good place. If only there were a safe route to find out about it beforehand."

Rushing in recklessly, not to mention the possibility of ending up in a monster horde, even if you're looking for a tree spirit or a substitute for the white velvet, you have no direction.

"By the way, I think Ian Boone left me a letter a while ago? It seemed to say... he's figured out the principles behind the 'Yarro Gara' armor and is already considering imitating or even improving it?"

Ian Boone is the fake 'Yaro' that Yaro met on the way when he first went to the market.

"I remember he seemed to have agreed in the letter to meet at the market in half a month. He was going to take me to a monster gathering point in the Dark Plains to show me his work?"

Yaro had no intention of accepting the invitation, after all, he was wanted and worried that others might set a trap for him, so he burned the letter at the time.

But now it seems that instead of gathering information from the market that may not be true, it's better to trust Ian Boone and accept the invitation.

"Half a month? That means there are only six days left. It will take another day to get to the market, so there are actually only five days."

If we accept the invitation, we will have to enter the Dark Plains, and we must prepare for battle in advance.

Five days... that's a tight schedule.

Having sorted out his thoughts, Yaro didn't delay any longer and directly ordered the maid waiting beside him, "Go and call Deputy Butler Dylan over."

"Okay, Lord."

……

Before long, Dylan, the assistant butler, hurried over.

"Lord Yaro."

"Ah."

Without further ado, Yaro asked directly, "How many carpenters and blacksmiths have you recruited so far?"

Craftsmen—that's the kind of human resource that Yarrow values.

"We have recruited thirty-one carpenters and three blacksmiths..."

Why are there so few blacksmiths?

Yaro frowned slightly. Without enough blacksmiths, some preparations would be difficult to complete.

Dylan respectfully explained, "Sir, it's mainly because there are no iron mines around here, and these blacksmiths usually only make farm tools..."
