On the sea, expedition ships mainly rely on wind power and the magic power accumulated automatically.

To put it bluntly, it is to rely on wind power to advance. Chen Yaogang can indeed provide wind magic support, but his cultivation level is not high and the effect is not ideal.

Compared with land, the specific heat capacity of seawater is larger, and the temperature needs more heat for every average increase of 1℃ of seawater. Taking deserts as a counterexample, the specific heat capacity of sand is smaller, and the temperature rises rapidly during the day and the temperature drops rapidly at night.

Although the chaotic dust blocks most of the sunlight and provides a relatively ideal hatching environment for the fragile seeds of the chaotic demon, the sunlight left at the beginning of creation itself has the component to restrain the power of chaos. Even if humans cannot see the colors of those lights with naked eyes, the temperature of the land during the day will still be slightly higher.

During the day, the air temperature on land is high, forming an atmospheric pressure difference, and the sea breeze mostly blows from the ocean to the land. At night, the two are reversed. The heat loss rate on land and desert is accelerated, and the wind will blow from land to the sea.

According to the theorem of hot, low pressure, cold and high pressure, it is sea breeze during the day and land breeze at night. As long as the environment is normal, Chen Yaogang is not worried about not being able to find the land. It is too luxurious to just burn rune navigation. Although Chen Yaogang has some small vaults, he will never do this unless he has to.

However, the Tomb of the Pain Ship is a key node to the ruins of the Sea God. The huge amount of magic energy accumulated in specific sea areas is likely to cause various strange phenomena.

One-eyed Kaira stood by the mast, the irritable sea breeze made her long hair dance, but she felt comfortable.

Seeing Chen Yaogang coming, Kaira showed a calm smile: "Hey, our King of Beasts seems to be inactive today. Are you busy studying the charts and not sleeping?"

Chen Yaogang rubbed his eyes: "I'm fine, I'm just trying to practice in the bumps, and I'm a little sleepy. How are you sure about the chart given by Alaisen?"

One-eyed Kaira unfolded a chart full of notes: "We are not lucky, and unfortunately, many of the floating islands of the Tide Night Watcher were broken by Chaos Meteors."

One-eyed Kaila pointed to the distance and handed the telescope over: "During this period, I and the observer kept a close eye all the way. All I saw were sinking floating islands. Some of them were even overturned. Basically, there was no need to expect to find survivors."

"The volcanic island on the chart is probably the sight of the volcanic lighthouse on the tide night watchman. Although the sight range of the rune lighthouse of the Tide Night Watcher is usually more than 30 nautical miles. However, we did not see the signal of the lighthouse. These chaotic meteors are everywhere, and they may have been occupied by monsters."

Chen Yaogang took the chart: "How is Alaisen?"

One-eyed Kaira took out a rational check: "According to your requirements, after passing the Illusion Soothing Therapy, Alaisen has been able to pass the rational check three times in a row, meeting the release standard. However, the other crew members seem to have failed the rational check for the time being due to the problem."

Chen Yaogang returned the chart to Kaira: "Landon, Miss Kaira sometimes needs to go to the room of Gem Lake to fill in magic, so those people will be left to you to deal with. During this period, you must prepare the weapons and equipment on the ship, and don't leave the daily naval combat exercises."

"Sailing alone on the Sea of ​​Pain, you will never know which one will come first, tomorrow or accident. The tactical knowledge about the fishman and ghost ship has been publicly explained. If you still don't understand anything, please ask Miss Kaila more and ensure that there are substitutes for each position. Do you understand?"

Langdon held his hands and listened attentively and handed over the complicated tasks to Langdon, which has gradually become Chen Yaogang's habit.

If Langdon is stronger, he is worthy of Chen Yaogang's equipment for him.

...

After two days and two nights of sailing, the Steel Cross was only 50% away from the Tomb of the Painful Boat.

But that night, Chen Yaogang woke up in the violent bumps.

When I opened my eyes, the lights swayed, and the air in the cabin was extremely depressed, which made me feel a little chest tight and uncomfortable. When I looked down, I saw that the armor and the bed were also marked by tide. The clothing and skin were sticky and sticky together, and my body and mind would feel uncomfortable.

When you step on the deck, you can see the chaotic dust in the sky surging. Many sea birds are flying in the waves, landing on the steel cross masts, looking like they are free to ride.

The dark black clouds fell in the sky, like an aging dragon hanging in the sky. There was a clear sound of thunder coming from the volcanic island. Looking at the lightning and calculating the speed of sound of the thunder, Chen Yaogang could quickly estimate the straight line distance between the steel cross and the volcanic island.

Alaisen walked to Chen Yaogang. After several days of training, he had accepted his identity: "Captain, the sea area seems to be about to usher in a storm. Miss Kaila feels it is not good to get close to that place. Do we want to give up on the island and go directly to the tomb of the ship of pain?"

Chen Yaogang held it on the railing and waved his hand to summon the storm crow and put it in the distance: "No, exploring the tomb of the ship of pain will surely alarm all kinds of sea monsters. If there is no stable lighthouse, sea monsters can find a way to attack the Steel Cross from directly below. At least there must be a night watchman's lighthouse so that we can hold on to the post of the sea monster."

Alaisen handed a log to Chen Yaogang: "This is the last call record that I made with other island investigators after the meteor impact. Although I guess they may have all died, Miss Kaila thinks it will be useful and let me hand over this information to you."

"Well, it's done well." Chen Yaogang opened the log and used the translation system to quickly observe and review it, with a hint of worry on his face.

Alaisen looked up at Chen Yaogang's side face: "Although the Volcanic Island is not a floating island, it is not easy for sea monsters to break through, but there have been a large amount of minerals there since ancient times. Before the Night Watchmen built the stronghold, some griffins and harps were entrenched there."

Chen Yaogang closed the log, his eyebrows ached slightly, and his shared vision with the Storm Crow was instantly interrupted. After flying less than 2,500 yards, his summoning object suddenly disappeared.

"There seems to be ghosts in that sea area. My summoning objects suddenly disappeared before reaching the maximum distance. But when we move forward, there are not many strongholds for the Tide Night Watcher. We cannot turn around and find the stronghold again, as it will be even more wasteful of time."

"The lighthouse base of this volcanic island is well located, so we must try our best to take it down, and everyone is ready to fight the island landing."

"Abide by the order!"
