The high-level wizards in this world may not be able to move mountains or fill the sea, but they can certainly turn decay into magic.

Because high-level mages have far greater sensitivity than ordinary people.

His sensitivity to future destiny, his sensitivity to the surrounding environment, and his sensitivity to subtle forces are all things that low-level mages cannot match.

Rosen not only has the sensitivity of a super high-level mage, but also has the fine control ability given by Lai Fu.

In the potions laboratory at the Sorcerer's Center.

Rosen, Laertris, and Vigo worked together again, combining all the knowledge of human body treatment to create a new healing potion.

The color of this potion is like gold, and its texture is like honey. It is packed in a magic-sealed arcane bottle, with a total volume of about 100 ml.

Wei Ge commented: "This is probably the most effective healing potion I have ever seen."

She felt that even if a person had died, as long as the body was not completely dead, after drinking this magic potion, the person would be able to come back to life on the spot and be full of energy, just like a healthy person.

Laertris chuckled and said, "What a coincidence. It's also the most powerful healing potion I've ever seen."

Rosen is not so optimistic.

"King Kao's body must have been on the verge of collapse. Kao's court potion master must have tried every possible way to treat him."

“This medicine may not be 100% effective.”

Of course, the drug is very effective.

This bottle of potion combines the sixth-ring "Gift of Nature", the sixth-ring "Flawless Steel Dragon Body", and Laltris's knowledge of pure water. It was finally successfully refined under the guidance of Wei Ge's genius alchemist and the overall meticulous grasp of Rosen, the tenth-ring wizard.

The name of the medicine: "Golden Blessing", the purpose is to extend the life of old King Kao.

The old king cannot die. Once he dies, the domestic situation in Kaa will be chaotic at best and turbulent at worst, and the control over Aaron will be greatly weakened.

At this juncture, if the little baron Rosen were to jump out and start a new route, he would definitely be hit by Aaron's iron fist.

After carefully putting away the precious bottle of golden blessing, Rosen said in a serious tone, "I have to go to Kao immediately. I'll leave the magic department to you, Wei Ge."

"I will take good care of it. All plans will be implemented in an orderly manner without any problems."

"But you, be careful."

Rosen smiled: "I'm not going alone. Lily and the guards will accompany me all the way on the sea. I will also bring various powerful protective magic tools."

The most important thing is that he has a body of steel. As long as he doesn't get carried away and fight others head-on, no one can stop him from leaving.

After saying that, he and Laertris smiled at each other and said, "Dear, let's go to the Eastern Banshee Port together."

Of course, we went there by electric carriage.

There is no need to worry about chaos in the territory, because Rosen has handed over the control of Puppet No. 2 to mentor Anna and left all the plans for the next month.

During his absence, the mentor will control Puppet No. 2 to help him manage the island.

If any special situation occurs, he can also control it remotely through the already built telegraph lines.

Soon we arrived at Eastern Banshee Port.

The Eastern Harbor is not open to outsiders for the time being, and the operation is secret, so there is no need to worry about information leakage.

There is already a medium-sized high-speed sea vessel loaded with clean black stone waiting at the port.

This ship was built by Master Belit and his shipbuilding team using the latest composite tempered materials, the latest version of power development, and at no cost, a massive amount of materials to create a high-speed ocean-going vessel.

The ship is named "White Swan". It is 50 meters long, 6 meters wide, and has a cruising speed of 20 knots, or about 37 kilometers per hour, and can reach a maximum speed of 28 knots.

Because it is equipped with a large amount of clean black stones, the cruising range reaches 9,000 kilometers.

If you take the Shenzhen Airlines route, it is not only enough to go to Cao and back, but you can also take a detour to the Flying Fish Islands in the East Golden Cape on the way back.

When Rosen arrived, 30 powerful battle mages had gathered in the cabin.

Among them there are 15 banshee warriors, all of whom have mana above advanced level, including two masters.

There are 15 other human battle mages, 5 of them are high-level mages and 10 are mid-level mages.

There are no warriors with fighting spirit.

Because naval warfare relies heavily on various spells, the role of the Battle Spirit Warrior is far less effective than that of the Battle Mage.

In addition, the cabin is naturally filled with various combat and long-distance voyage supplies.

When Rosen and Laertris arrived, everything was ready.

After getting on the boat, Rosen said, "Let's go."

"Woo~~~~"

The ship shook slightly, and the pointed bow cut through the waves steadily. The ship slowly accelerated and headed southeast.

According to the plan, they would sail southeast into the deep sea to avoid encountering other naval fleets on the way and disclosing Rosen's plan to go south.

Once they reach the deep sea, Laertris will act as the navigator and guide the White Swan to take the safest and most labor-saving route.

After a while, the White Swan increased its speed to about 20 knots and maintained stability.

This speed is far ahead of the current sailing warship's speed of around 10 knots.

Even if you encounter an unexpected situation, such as pirates or warships, you can easily get rid of the opponent.

After sailing for more than an hour, the White Sturgeon left the White Sturgeon Island far behind, and the sea surface gradually changed from light blue to dark blue, and then turned to dark blue bit by bit.

At the bow of the White sturgeon, Laertris softly introduced the sea conditions to Rosen.

Rosen made a brief estimate: "In other words, the straight-line distance is about 3,000 kilometers."

Because Laertris's long-distance flight speed is 100 kilometers per hour, and because of the wide wings brought by the transformation, they can also make great use of the sea breeze to glide, and can even rest on the "wind", so their endurance is very strong.

If she is lucky enough to get the help of the sea breeze, Laertris can fly for more than ten hours in a row and cover more than a thousand kilometers in one breath.

Of course, if you use sprint flight, the speed can reach nearly 200 kilometers per hour, and you will soon be exhausted, so you have to fight for your life.

At the speed of the White Sturgeon, it would take about four or five days to travel in a straight line.

After sitting for a while, Laertris said, "The boat ride is too slow, why don't we fly over there?"

Rosen shook his head: "The old king should be able to hold out for half a year, so these few days won't matter. It's also a good opportunity to accumulate deep-sea sailing experience."

"All right."

At this moment, there was endless deep sea in front, behind, and on both sides of the White Sturgeon, and there was no reference point to be seen on the sea surface.

And there is no GPS positioning these days. If you want to ensure direction, the biggest reference during the day is the sun in the sky.

Laertris is very experienced in this regard, and she carefully teaches the human battle mages.

"The sun is at different altitudes at different times of day in different places."

"So, when you refer to the sun to tell the exact time, you must pay special attention to this."

After driving for a while, she said, "There are invisible rivers in the ocean."

"There will be a part of the sea water that flows in a unique direction. When a ship enters this current, it is easy to be carried off course."

"The direction and position of these currents will change with the seasons, but don't worry, I have carefully memorized every current in the Golden Ocean."

A battle mage asked: "Madam, if there is no sun and the sky is full of dark clouds, how can we tell the direction and determine our position in the deep sea?"

Laertris clapped her hands gently. "Good question!"

"According to my recent understanding, in such a situation, even ships sailing close to the coast will lose their direction and fall into an extremely dangerous situation."

"But fortunately, pure water will tell us the answer."

“Two methods.”

"One is pure water divination. Of course, it's not the pure water divination you use now. The method you use is somewhat useful in the near sea, but it's useless in the open ocean."

"This is our unique pure water divination technique. I can't say about other sea areas, but it is quite accurate in the Golden Ocean area. Unless it is interfered by the magic, it will not go wrong."

"The second thing is to use the seabed topography for positioning."

She looked at the human warriors and mages on the ship, and indeed saw surprised expressions on their faces: "Yes, there are mountains and plains on the seabed."

"Using the Banshee Scream technique, I can obtain the detailed topography of the seabed. By comparing it with the seabed map in my mind, I can know my exact location."

"With these two methods combined, it will be difficult for you to get lost in the Golden Ocean."

Rosen was very happy as he watched Laltris impart knowledge of ocean sailing.

"I'll have to ask the witch to open a class on ocean-going magic in the future."

Because the 'White Sturgeon' is equipped with a unique underwater ultrasonic device, there is no need to worry about being disturbed by the giant beast.

The ship sailed smoothly all the way and fortunately did not encounter any storms on the way.

By dusk on the fifth day, the White Swan had successfully reached a desolate coast in northern Kao.

70 kilometers to the north is the famous seaport city of Baisha City in Cao.

Following the Orel River that flows through Baisha City all the way southeast for more than 200 kilometers, you will reach the capital of Cao.

Silvermoon City is known as the 'City of Roses', the 'City of Central Gold', and the 'Hometown of Knights'.

Of course, the last 270 kilometers cannot be traveled along the river on the Sturgeon, because Rosen does not want electric power to appear in Witt Continent so early.

Naturally, he couldn't transform into a steel dragon body and fly over.

Because the strong fluctuation of mana will make Rosen the spotlight in the sky.

Approaching the capital of the Natural Alliance in this state would be tantamount to seeking death.

The safest way is, of course, to find a good horse and run low-key on the ground.

If we keep changing horses in the relay, we will arrive there quickly.

"Plop~~"

Rosen jumped off the boat alone, carrying a long wooden box filled with various magical instruments.

"You guys find a hidden bay nearby and wait for me. I'm heading to the capital of Cao now and will be back in a week at most."

Then he looked at Laertris: "We can contact each other by telegram at any time."

"Okay. Be careful on your way."

Although she really wanted to go with Rosen, she was a deep-sea banshee and did not dare to easily go deep into the heart of the Natural Alliance Kingdom.

After everything was ready, Rosen cast a magical power of speed on himself and ran towards the nearby village.

Soon, his figure disappeared into the night.
