My health recovery is incredibly fast.

The last few pages are illustrations, showing common fire-breathing postures, diagrams illustrating the relationship between environmental wind direction, exhaust flow, and flames, as well as self-rescue methods in emergency situations.

Yes, very detailed.

Xia Zuo nodded silently, closed the book, and watched the eldest sister fiddling with the alchemy equipment in the suitcase.

Audrey is a first-rate knife thrower with exceptional dexterity. Her hands are incredibly nimble, and she handles glass bottles with ease. Her skillful technique and fluid movements surpass even Vans's.

She used a mild flamethrower and fire retardant, along with other protective agents, to create a new flamethrower.

Xia Zuo casually cast a detection spell.

"Audrey-type weak mixed flamethrower has both fireproof and flamethrowing effects."

"After holding it in your mouth for 3 seconds, the fire-retardant oil in this medicine will form a fire-retardant layer in your mouth."

"After holding it in your mouth for 5 seconds, the weak flamethrower will completely separate from the fire retardant, at which point you can spit it out."

"Drinking this will cause physical damage, resulting in a loss of 30 health points over 60 minutes. Holding it in your mouth will result in a loss of 3 health points per hour. Successfully breathing fire will grant experience."

Wow, using multiple potions together not only significantly reduces the amount of blood loss caused by toxicity, but also doesn't weaken the fire-breathing effect at all.

Xia Zuo raised the corners of his mouth, suddenly thinking that having the eldest sister work part-time as a fire-breathing teacher seemed quite reliable.

The flamethrower she concocted looked much better than Vans's.

"Little guy, let's start learning how to breathe fire."

Audrey sat at the table, letting the boy sit close to her so they could read the fire-breathing training instructions together.

Chapter 11 Improving Efficiency

The next day.

The circus is about to leave the city that witnessed the birth of a new fire-breathing creature.

Before the convoy departed, Xia Zuo carried his medicine case to the third carriage.

Originally, he wanted Audrey to keep it safe, but there was just too much stuff in the first carriage, and there was no room to spare.

Then it can only be placed with Vans's suitcase.

The two suitcases are different in appearance, so they won't get confused. Xia Zuo's is new, while Fan Ersi's is older, and their lock cylinders are also different.

He handed the keys to Audrey and then read the fire-breathing training manual in the car.

Yesterday I spent the whole day practicing fire-breathing with Audrey. The fire-breathing potion tasted bitter, but I could tolerate it, and I also learned some very simple alchemical techniques along the way.

When you hold the Audrey-style mixed flamethrower in your mouth, you will enter a state of continuous health loss, with the amount of health lost and the amount of health restored being exactly equal.

For Xia Zuo, apart from a numb mouth and a thirst, there were no other effects.

Once you successfully breathe fire, you can gain a wealth of experience!

"Completed 1 fire-breathing training session, lasting 2 seconds, gaining 0.002 experience points."

Based on the calculation that 0.001 experience points are awarded per second, 1 seconds of spitting flames will earn 1 experience point.

If it were to spew out flames three meters long in the future, how much experience points would that give?

Including the reward for performing fire-breathing for the audience

Xia Zuo sat on the floor of the carriage and couldn't help but laugh.

"Hey little guy, you seem to be in a good mood," his roommate, the strongman Popeye, said with a grin.

As the carriage started moving, both of them leaned back slightly, but quickly regained their balance.

"I think I'm very suitable for fire-breathing performances. I can already breathe fire, although it doesn't last long."

Xia Zuo smiled slightly and took out a miniature bouncy ball to exercise his strength.

After gaining 1 point of strength with this little thing, you need to complete 1 million training sessions to get the next point. The number of training sessions has increased tenfold, and the upgrade experience you can get has also been reduced by 100%, for a total of only 5 points.

Joe also took out his bouncy ball, "Hehe, with Big Sister helping you train to breathe fire, you'll definitely be as good as Vans."

Two figures, one tall and one short, were vigorously pressing and squeezing bouncy balls inside the carriage, their bodies swaying with the carriage's bumps.

Two months later.

The circus has entered the southern part of Rosac province.

Xia Zuo's destroyed hometown was a little further south, near the border of the kingdom.

Ever since the bandits invaded this area, it has been a very unstable place.

In the hotels I passed by, I often heard rumors that certain villages had been looted and burned to ruins.

The circus stopped at the fortress of Pijek in the southern part of Rosac province.

This is the midpoint of this round of travel plans, the point where we'll turn.

The leader didn't plan to go any further south to avoid running into the bandits. After their performance in this fortress, the circus would head north and return to Rosac via another route.

Unexpectedly, on the very first day of my arrival, I encountered a joyous event that completely disrupted my travel plans.

Piek Fortress was both a city and a military stronghold. In addition to ordinary citizens, troops were also stationed there.

The bandits were rampaging through the protected area of ​​Piek Fortress, and the army was busy rescuing and suppressing the bandits. The soldiers were exhausted and desperately needed some performances to boost morale.

The arrival of Audrey's Circus came just in time to relieve the fortress commander's urgent need.

When the leader returned from the fortress, she announced some good news with a beaming smile:

The circus accepted the fortress commander's invitation and will stay in Piek for about a month to perform for the soldiers returning to the fortress for rest!

This is a very reliable and lucrative deal! There's no reason not to accept it.

Piek Fortress is not the commander's private property; like Rosac City, it is a city under the Rosac Council.

The circus's performance fees here are directly funded by the Rosac Council, rather than by the fortress commander's own pocket.

There is absolutely no possibility of defaulting on the debt.

The leader guessed that if the performance was good and the soldiers' morale was boosted, there might even be an extra reward from the fortress commander.

This conjecture is reasonable and well-founded.

The fortress commander not only placed a large order with the military, but also used his own money to do something that won the hearts of the people.

When Audrey returned, she was carrying a bag full of coins.

The commander of Piek Fortress was a kind, generous, and compassionate ruler.

He took out a sum of money and booked all the circus performances in the fountain square, inviting the residents of the fortress to watch the show.

For the next six days, any resident can line up to watch the circus performance, with guards responsible for maintaining order.

When Xia Zuo returned to his room with the heavy bag to count the money and make accounts...

His heart and hands were trembling. Not because he had so much money...

But

This...this...this...such a huge sum of money, and they didn't give us a single bit of experience.

So, the money from ticket sales only counts if he gets it from the customers himself.

The 10 silver coins and hundreds of copper coins that the leader brought back were worth about 14 experience points each.

Xia Zuo didn't get a single experience point. Looking at the character template information again:

Level 5

Experience 0.9200

I just leveled up a few days ago.

5级升6级需要200点经验，是4级升5级的4倍。

Roughly estimating, under normal circumstances, it would take about five or six performances to advance to level 1, and the next promotion would be three months later.

The circus will be stationed in the fortress for a month, performing for both civilians and soldiers.

The money from the commoners was paid by the fortress commander.

The soldiers' money was paid by the Rosac Parliament.

These two waves of income were brilliantly delivered; I didn't gain a single point of experience.

Without the experience gained from ticket revenue, relying solely on the income from reading books, doing odd jobs, and training fire-breathing will result in extremely low experience gain efficiency over the next month.

After Xia Zuo finished recording the accounts, he didn't immediately send them to the boss. Instead, he sat at his desk, deep in thought, considering whether he should go on stage early.

Over the past two months, he has been exploring a fire-breathing method that suits him, aiming for a stable and safe upgrade.

The experience points are calculated based on two dimensions: the duration of the fire-breathing action and the size of the flames.

A flame the length of two fingers grants 0.001 experience points per second.

The success rate is now 100%. Holding a mouthful of fire-breathing agent, you can continuously spew it for about 20 seconds.

A small flame, 0.5 meters long, grants 0.002 experience points per second.

The airflow is delivered faster, and each puff can only last for 5 to 7 seconds. Occasionally, you may choke or be interrupted by other unexpected events, but the success rate is over 90%.

Xia Zuo has a very low success rate with flames longer than 1 meter, mainly because his lung capacity is insufficient, making it difficult to maintain the flame length above 1 meter. He can gain 0.003 experience points every second.

Vans can maintain a 3-meter-long fireball for nearly 10 seconds, which is due not only to his rigorous training in lung capacity and the help of fire-breathing agents, but also largely to his breathing techniques.

During her fire-breathing lesson, the leader revealed all about breathing techniques without reservation.

Adults aged 18 and over, regardless of gender, can accept quests from the Warrior's Guild and use the points earned from completing the quests to exchange for breathing technique training courses.

The easiest task to get into is joining the army.

The soldiers in Piek City Seri were almost all there to complete their mission.

The vast majority of soldiers, after completing their missions, do not use their points to exchange for breathing technique training courses. Instead, they exchange them for well-paid jobs or military rank rewards to continue their hard work and advancement in the military.

Very few people would spend their points on extremely unstable breathing techniques.

When anyone practices breathing techniques for the first time, they can use supplementary potions to randomly and permanently strengthen a certain part of their body with a very small probability. The price is that another part will undergo irreversible, non-malignant mutations.

This process is called potential development, or potential tapping.
