In the past three years, the Ruyi has also changed a lot, and the alchemy runes of the old El can make the Ruyi absorb cold air, and the original Ruyi can absorb cold air, so the effect of the bow statue of the little penguin ship is only to accelerate.

When Zhang Yi carved the runes that absorbed cold qi in the form of jade runes, Ruyi's ability to absorb cold qi suddenly broke through, not only did the ice water not freeze, but he could directly absorb the cold water and vaporize it.

Because the Ruyi has swallowed enough metal and has the characteristics of deformation, when it was on the island, in order to absorb the cold air of the ice in the distance, the Ruyi actually slowly approached the glacier, and the anchor chain was automatically extended to one hundred and fifty meters.

After Zhang Yi discovered this secret, he then transformed the drive of the Ruyi, the original pump was canceled, and the inlet pipe commanded the Ruyi to slowly twist into a coil, and after the Ruyi sucked the seawater into the pipe, it directly absorbed the cold air through the coil, because the coil was long enough, the seawater heated and vaporized, and finally spewed out of the vent.

This is similar to the power of a jet aircraft, the advantage is that the power is strong and the speed is fast, and the disadvantage is that after the Ruyi sails, there is a long trail behind it, and the sea water is full of white bubbles.

The Ruyi hull absorbs cold air, and there is also a propulsion force, which is the front side of the hull, and the part of the seawater that touches the hull is vaporized, and when the Ruyi advances, the resistance of the seawater becomes negligible, and even gains the propulsion force to move forward.

The Ruyi originally had a water purification device and a negative oxygen ion generator, but after this transformation, Zhang Yi also solidified these two functions directly in the Ruyi hull, and finally even the battery was integrated with the Ruyi.

In the early days, when the Ruyi sucked lightning, it had already broken down the battery system, and then the excess electricity generated by the solar energy was absorbed by the Ruyi. At that time, the Ruyi was unscrupulous in absorbing energy.

During this transformation, Zhang Yi directly solidified the battery in the hull of the Ruyi, with sufficient energy of the Ruyi, the power supply pile head of the battery will never lack of electric energy, lighting, electronic instruments and living electricity all come from the energy of the Ruyi.

The last stop of Zhang Yi's parade was Wuzhi Mountain, where he not only carved runes on the mountain and buildings of Wuzhi Mountain, but also studied a plan to completely transform the Ruyi.

Originally, the Ruyi was the same as other ships, it was easy to confuse, but now when the Ruyi sails, it brings out a long bubble trail behind it, and it looks different, and the Ruyi can be seen from a high altitude.

The Ruyi has become a target like a beacon, and there is no safety, except for the Yuxia range, the high seas dare not open randomly.

Zhang Yi and a group of elite scholars, after formulating a variety of transformation plans for the Ruyi in Wuzhi Mountain, took advantage of the night and rushed directly to Ruyi Island. Zhang Yi only completed the integration of power and hydropower, instrument integration, and laser weapon integration, all of which were carried out in the shipyard. Moreover, the instrument and laser system on the Ruyi are outdated, and since they are solidified and integrated, they must use the latest laser system.

That night, the ships along the route heard the roar of jets, of course they didn't think that it was the Ruyi, let alone that the speed of the Ruyi had exceeded 300 knots, if it wasn't for the weight was too big, the wings were too short, it really had to fly.

In just one night, the Ruyi sailed from Wuzhi Mountain to the Ruyi Island shipyard, in order not to expose the target, when it reached the nearby two hundred nautical miles, the Ruyi deliberately slowed down and quietly entered the Ruyi Island shipyard.

The transformation of the Ruyi is first of all to remove the superstructure.

Among the various transformation schemes, Zhang Yi's favorite is the dolphin-type submarine, the front tip can break the water, the lower side of the widenose can enter the seawater, the dorsal fin, flipper foot and tail fin are densely covered with fumaroles, when you need to move quickly, the water inlet is the largest, and the five fins spray water at the same time. Usually moving slowly underwater, Zhang Yi can use his divine sense to direct the cold and spray water.

Similar to the shape of a dolphin, the Ruyi can also get the largest cabin, as long as the volume is guaranteed to be suspended in the shallow sea for about 15 meters, the titanium alloy hull is very strong, can withstand the pressure of the seabed, comes with oxygen supply equipment, and the turbidity can also be discharged with the jet.

The bulge of the dolphin's head is equipped with lidar and laser cannons, because the Tianhe satellite has a set of long-wave signal transmitting devices, which can be received by the entire earth, and the signal is still strong at 200 meters underwater. The entire body of the Ruyi capsule can be used as a signal collector, even 200 meters below the sea surface, it can also receive satellite signals, and the Ruyi can understand all the information as long as it does not dive into the deep sea. As long as it floats to a depth of 15 meters, it can send a communication signal.

The Ruyi not only has the long-range combat ability of laser cannons, but also the means of close combat.

Zhang Yi obtained an axe and a magic sword from the cave of Jiran Island, and the axe was devoured by the Ruyi, leaving only a beautiful hand axe of one hundred and fifty kilograms.

The magic sword was originally going to be given to Tang Ru, but Tang Ru only liked the dragon and phoenix sword polished by Zhang Yi himself, so the magic sword was also swallowed by the Ruyi, leaving only a scalpel-sized edge as Zhang Yi's finger knife.

The Ruyi can be transformed, it starts after devouring this magic sword, and under Zhang Yi's command, any place in the Ruyi's body can emit a sword ray of nearly fifteen meters, once cutting a Xiaoice mountain in half.

The blade is indestructible, it can break the ice and sink enemy ships, all it takes is to quickly approach the ship and use it to make a hole in the bottom of the ship.

The four anchor chains of the Ruyi are still retained, but they become four claws, usually four stubby legs, shrunk in the belly of the Ruyi, and the anchor type can also be deformed, under the command of Zhang Yi, it becomes the shape of four claws, grabbing objects on the bottom of the sea.

The magic sword caused this change in the Ruyi, which made Zhang Yi have a new guess, after the ancient sword cultivator made the long sword bigger, he flew directly on the sword, maybe it was true.

It's just the finger knife in his hand, no matter how Zhang Yi commands with divine sense, except for sending out a half-meter-long sword, there is no change.

In the Ruyi Island Shipyard, it took a whole year for Zhang Yi to completely transform the Ruyi, and then he took Lu Fangting with him, preparing to go back to Yuxia to pick up Tang Rudani and Ye Yichen.

He was going to take the four of them around the world with the Ruyi. Then he took Wang Yi and Liu Fang to the sea to practice. After years of cultivation, Wang Yi and Liu Fang are now in the middle stage of condensation, and there are still a few years before the foundation is built, and Zhang Yi will take them to cultivate on the Ruyi, which will definitely be faster than cultivating in Yujing.

In order to stop the formation of bubbles on the sea surface, Zhang Yi can only use a speed of sixty knots to sail at a distance of fifteen meters below the sea surface, the thirty-six meters long Ruyi, which can accommodate people's cabins, is twenty-four meters, and is divided into six cabins, like a large apartment suite, fully functional, but a long strip, except for the display on the wall, there is nothing in it, and the matter of arranging the room is for the woman to decide.

As a result, the Ruyi arrived in the East China Sea, and Zhang Yi suddenly commanded the Ruyi to stop and start diving.

On the Ruyi, Zhang Yi enjoys the ultra-far range of the Ruyi's divine sense, as long as it is not a deep-sea trench, he can know everything on the bottom of the sea.

He commanded the Ruyi to turn around and dive because it seemed that he had found a large bomb with a very strange shape in the trough just now. Because the water depth of that place was about 1,200 meters, Zhang Yi's divine sense did not see it clearly, so he turned around and came back to take a closer look.

The Zhang Yiba Ruyi dived to a depth of 1,000 meters, and then released two anchor chains, which quickly lifted the bomb from the bottom of the sea.

Encountering such a large bomb, Zhang Yi did not continue to move forward, but turned to the outer side of the islands, and during the voyage, he began to study the bomb carefully.

He didn't need to take it apart, he just used his divine sense to scan it, just like he had stolen the experimental equipment and dismantled the sparrow to analyze the bomb.
