To the east of the Great Yan Country, there is an endless sea, and no one can say how big the area of the ocean is, only that this is the end of the entire Great Luo Continent continent.

People on land never know the horror of the sea, when a person stands on the seashore, he will feel the immensity of the sea, and he will feel that his chest is full of fierce passion, but these people do not know what kind of situation a person will face when he enters the depths of the sea.

The sea is turbulent, the weather is myriad, and unexpected changes may occur at any time, at this time the sea is still calm, gentle and drizzly, and in an instant, there may be lightning and thunder, wind and rain.

Moreover, the sea is vast and bottomless, and no one can say what kind of creatures exist in it. The ocean is very large, there are no clear markers in the sea, so it is very easy to get lost, and the most important thing is that there are very few islands in the sea, once you enter the sea, if you lose your way, you may drift farther and farther in the sea until you run out of supplies.

It is true that the resources in the sea are very rich, but this rich marine resources are extremely difficult to obtain, unless it is the kind of land gods who come and go high in the sea, ordinary people have no other way to cross the ocean, they can only use equipment, such as sea ships to sail. And on the sea boat, it is quite difficult to catch marine fish, especially the lack of fresh water, is also a fatal factor, the general sea boat, even with sufficient supplies, the ability to continue navigation at sea will not exceed a month and a half, beyond this time, the resources on board will be exhausted, at this time, it is necessary to replenish the supply in time.

Generally speaking, the most important supplement for sea ships is the replenishment of fresh water and diet, in which the collection of fresh water relies on the accumulation of rainwater, water vapor collection and other methods, but these methods are greatly affected by weather changes, if it catches up with a period of time without rain, then the accumulation of fresh water is a big trouble.

As for the diet, when the diet in the land zone is exhausted, it needs to obtain resources from the sea, such as marine fish, shellfish, molluscs, etc. However, it is not easy to catch marine fish, if you pass through the fishing area, not to mention the abundance of fish, but if the area through which the wind and waves are strong, the fish sink to the bottom, then fishing becomes a problem, and it may be extremely difficult to catch the fish you need.

Therefore, the output of resources in the sea is far less stable than that on land, and it is too affected by the outside world.

Yuntian entered the sea, there was no problem with his diet, with his cultivation, he only needed to catch some sea fish every other distance, it was really not good, he could enter the sea space, it was impossible to starve him.

The fresh water in the sea space is also enough, including cooked food, all kinds of wine and delicacies, which can be produced in the sea space, Yuntian for the convenience of traveling on the sea, and let the demons and humans in the sea space work together to create several large ships, and he chose a tool for sea navigation.

Because of the unpredictable changes in the deep sea, so Yun Tian did not look for a helper, he made a modification of the sea ship, there are several tough ropes on the ship to control the sails, and there are two big rollers on both sides of the hull, Yun Tian is driven by true qi, the rollers run quickly, plus the traction of the sails, it drives the sea ship to move forward, this kind of sea ship can be controlled by one person, of course, it can only be controlled by people of Yuntian's strength, and I am afraid that it will not be able to play at all if you change people.

According to Yun Tian's estimates, his sea ship weighs at least two or three hundred tons when fully loaded, which is already a very rare big ship, no matter how big the ship is, it is still very difficult to overcome in terms of the technical level of the demons and humans in the current sea space, and only after a period of time, the skills of those shipbuilders are upgraded to a new height, and they can make larger sea ships.

In fact, even if it is such a big ship, it is already Yuntian who has added several formations to it to stabilize the hull of the ship, so that the big ship has enough toughness, if it is a simple shipbuilding skill, the demons and humans in the sea space still can't meet those requirements.

At present, the sea ship in the cloud sky plus the formation, sailing in the sea can also withstand the wind and waves, and after the cloud sky attaches a few formations, the stability of the sea ship has also improved, although after entering the deep sea, the wind and waves are strong, but with the blessing of the circle, it makes the sway of the sea ship from irregular left and right swing up and down to regular traverse, and people feel much more comfortable on the sea boat.

At this time, Yuntian drove a boat on the sea alone, accompanied only by his cute pet, Tianyi Flying Tiger Tiger Xiaobao.

When he first entered the sea, Hu Xiaobao was very excited, he spread his wings, jumped east and west on the boat, and drank back and forth, but after a few days, Hu Xiaobao's interest faded a lot, and after more than ten days, it was so bored that it hung in the basket next to the side of the boat and fished in the water with its tail......

The reason why Yun Tian got Hu Xiaobao out was also to not be lonely on the journey, of course, he could also summon more people, the problem is that there is no point in doing so, Delisi and the others are also new to the sea, not to mention that they can't help too much, but it may cause chaos, and Yun Tian is searching in the deep sea, completely relying on his own spiritual sense, and others can't help at all.

Unlike Hu Xiaobao, who was in a lack of interest a few days later, Yuntian was not idle on the way.

Sailing in the vast sea, without any references, the so-called positioning according to the angle of the stars and sunlight is completely useless for such a novice, and it is very difficult to figure out whether your course is correct or not, and the change of position in the sea. Fortunately, Yuntian had another means, which made him feel a little more confident when crossing the sea.

In the vast sea, in order to determine his position, Yuntian adopted the method of true qi positioning.

The so-called True Qi positioning means that Yun Tian uses his True Qi to leave a mark on the bottom of the sea every distance, and he uses his spiritual sense to scan the true Qi markers on the bottom of the sea to determine his movement speed and direction. With Yuntian's current cultivation, even if it is a hundred kilometers away from the breath he released, he can also sense it, so Yuntian will take the method of parallel positioning, and when he leaves the port, he will drop a sign on the seabed, and then throw a sign when he travels a distance to the east, so that as he sails more distance, there are more and more such signs, and more signs will be easier to determine the direction on the bottom of the sea.
