To the First Emperor of Qin: The state has decreed this!

"Considering the average speed of the Qin Dynasty fleet, and the time allotted for resupply and rest along the way!"

"A conservative estimate... would take at least forty days one way!"

The computational experts yielded astonishing results.

Forty days!

This means Zhang Fan will be at sea for forty days!

"No modern navigation!"

"Instead of following this coastal route, they would have attempted a direct crossing!"

"The risks will increase exponentially."

The navigation expert added,

"Once we deviate from our course, we could be lost forever in the Pacific Ocean."

Zhu Feng's expression also darkened.

He immediately ordered that Zhang Fan be contacted.

"What? Forty days?"

He heard Zhu Feng relay the flight route and time.

Zhang Fan immediately denied it.

"Sir! What a joke!"

"Rocking on a ship for forty days? I'd be rocked until I'm internally injured!"

"No, this route is absolutely unacceptable!"

He made a decisive decision:

"I want to go in a straight line! The fleet must depart in three days!"

Upon hearing Zhang Fan's resolute stance, Zhu Feng pondered for a moment, a decisive glint flashing in his eyes.

"Zhang Fan, are you sure you want to take this risk?"

"Crossing the ocean directly is extremely risky!"

Zhu Feng asked.

"Sir, I'm certain! I'd rather take the risk than spend forty days adrift at sea!"

"I believe in our technology, and I also believe in the courage of the Qin people!"

Zhang Fan's voice was resolute.

Zhu Feng ultimately agreed to Zhang Fan's decision:

"Great! The battery level is currently more than sufficient!"

"This risk...we can afford to take it!"

"However, you must stay connected at all times, and we will do our best to provide you with guidance!"

"No problem! The expedition will set sail in three days!"

Zhang Fan hung up the call, his eyes gleaming with excitement and determination.

He is currently standing on a high platform!

Below are the busy disciples of the Mohist school.

Five thousand elite troops have already set off ahead of time, heading towards Langya Port on the coast of the East China Sea.

Meanwhile, the Mohist disciples inside the Institute of Natural History were making final preparations for resupply.

The courtyard was filled with a large number of earthenware urns for storing water and sealed wooden barrels.

The Mohist disciples, in groups of three or five, would reinforce the earthenware urns with ropes or carefully apply tung oil to the wooden barrels to ensure that not a drop of water would leak through.

"Immortal Master! Immortal Master!"

As Zhang Fan was deep in thought, Mo Feng rushed over.

His face showed a hint of fatigue, but even more so, confusion.

"Master, what is the purpose of these wooden buckets and earthenware urns?"

"Why store so much freshwater?"

"The sea is rough, and freshwater is difficult to store. Once it spoils, it could lead to disease outbreaks..."

Before he finished speaking, the Mohist disciples around him stopped what they were doing and breathed a sigh of relief.

"Yes, Immortal Master!"

"We've been making wooden barrels non-stop these past few days, and our hands are almost blistered!"

A young member of the Mohist school complained.

"It's not interesting at all like studying natural phenomena; it's just boring!" another person chimed in.

"These earthenware urns and wooden barrels can store tens of thousands of kilograms of fresh water!"

"But even without considering the spoilage of freshwater at sea, this quantity still takes up most of the ship's cabin space, increasing the fleet's load!"

An elderly member of the Mo family also frowned in confusion.

He understood navigation and the importance of a fleet's carrying capacity.

Looking at his somewhat resentful disciples, Zhang Fan couldn't help but find it amusing.

This is the Mohist school!

pragmatic!

It also carries with it a pure pursuit of knowledge!

He smiled gently, his tone reassuring:

"Thank you for your hard work, everyone!"

"These wooden barrels and earthenware urns were naturally for storing fresh water for use during sea voyages."

These words were spoken.

Instead of answering everyone's questions, it sparked even more discussion.

"Master, you heard it yourself, freshwater at sea spoils very easily!"

A member of the Mohist school raised another question.

He has conducted in-depth research on this.

"I have heard that some ocean-going fleets store drinking water!"

"I'd rather prepare sake brewed in winter and sealed in mud. It can be preserved for more than six months without spoiling, and drinking it can refresh and warm the body!"

"Isn't it better than fresh water?"

These words resonated with many Mohist disciples, who whispered amongst themselves, discussing Zhang Fan's lack of knowledge about navigation.

Hearing the conversation, Zhang Fan knew it was time to show off his skills.

A slight smile played on his lips as he pulled a small white plastic medicine bottle from his pocket.

It is indeed a water purification tablet!

Gently twist open the bottle cap and pour out a white pill.

Everyone's attention was immediately drawn to the pills.

They stared wide-eyed at the water purifier tablet in Zhang Fan's hand with great curiosity!

This thing is so thin and light!

What's the use?

"Gentlemen!"

Zhang Fan held the pills in his hand and said slowly.

"What you say about freshwater being difficult to preserve and prone to disease is true!"

"However, with this..."

He held up the white pill in his hand and continued,

"Simply put this into the filthy water, and it will become clear and drinkable, and will not easily spoil."

As soon as he finished speaking, the entire Gewu Institute fell silent.

The eyes of all the Mohist disciples changed from curiosity to shock!

Then came disbelief!

They looked at each other, their faces filled with the same question:

Is that... even possible?

They are the Mohists!

They admire the pursuit of knowledge through investigation, and they revere science and logic!

Water can spoil, and I know very well that filthy water is not drinkable!

That's a conclusion drawn from lessons learned!

But the immortal master actually claimed that a small white pill could turn "filthy water" into "drinkable water"?

This is not the way of investigating things pursued by the Mohists!

The immortal master is about to unleash his magic again!

"Immortal Master, is this... truly true?"

An old Mohist disciple asked in a trembling voice.

He had been engaged in water conservancy research for decades, but had never seen such a thing before.

Looking at the shocked, surprised, and even fanatical eyes of the crowd, Zhang Fan felt satisfied.

That's the allure of technology!

Compared to the ancients, some modern everyday items appear quite extraordinary!

"This is a water purification tablet!"

Zhang Fan slowly began to speak.

"Its principle lies in its ability to quickly kill bacteria in the water, settle impurities, and restore the water's clarity!"

"Kill germs? Settle impurities?"

The Mohist disciples began to whisper among themselves, filled with doubt and skepticism.

These words are completely unheard of!

Mo Feng's eyes burned with fervor as he turned to the other disciples beside him and shouted:

"Quickly! Go and fetch a basin of the filthiest, stagnant water!"

"It has to be the kind that would make most people nauseous!"

Several Mohist disciples immediately rushed off!

A short while later, a basin of dark, murky water was brought over.

The water had a faint fishy smell and was covered with unidentified decaying leaves and insect carcasses!

"Immortal Master, please!"

Mo Feng respectfully placed the pot of bad water in front of Zhang Fan, his eyes filled with anticipation and nervousness.

He both longed to witness it and harbored a hint of doubt.

Zhang Fan took the white pill and, in full view of everyone, threw it into the basin of water.

"Pfft..."

With a barely audible sound, the tiny white pill began to dissolve immediately upon contact with the water.

Followed by.

An astonishing scene unfolded!

Tiny bubbles began to rise to the surface of the water!

The decaying leaves and insect carcasses floating on the water's surface began to slowly sink!

The mud and impurities in the water also quickly condense into flocculent matter and rapidly settle to the bottom of the basin.

Several dozen breaths later!

The stagnant water in the basin actually became clear!
