After successfully sharing the stealth ability, Chu Chen immediately tried it.

　　 Then, he will disappear from others' sight.

　　 Chu Chen discovered that this stealth ability is somewhat similar to the principle of light refraction, but there are some differences.

　　 If you are close, this ability can only deceive your eyes, and there is no way to achieve invisibility under the exploration of mental power.

　　 In other words, Chu Chen didn't start a thunder and lightning storm before, but instead used the spiritual talent shared from Caiwei to detect with his superior spiritual power, and he could also find this guy's location!

　　 This ability of the ancient octopus can also be continuously upgraded as it evolves.

　　 The current invisibility still has some flaws.

　　 is not in a hurry.

　　 After the ancient octopus evolves for a period of time, this ability will become even more powerful!

　　.

　　 Although this ancient octopus was injured not lightly this time, this guy's recovery ability and regeneration ability are also good, and the regeneration ability, but can reopen the broken limbs.

　　 After allocating the evolution points, this guy's injury should also be recovered.

　　......................

　　 "Your Excellency Chu Chen, how is it?"

　　 At this time, the mermaid patriarch swam over and asked.

　　 Chu Chen said: "Don't worry, it has been tamed by me. The ancient species have already retreated, right?"

　　 The Mermaid patriarch nodded, his eyes filled with gratitude, and said: "Yes, all the ancient species have retreated, this time thanks to Your Excellency Chu Chen."

　　 Chu Chen: "It's okay, you must have been tired after fighting for so long, so go back and take a rest and replenish your energy."

　　 The mermaid patriarch said: "Well, okay, what about you Chu Chen?"

　　 Chu Chen said: "I will explore further east to see if I can find some seabed gold in the east, and by the way, have these ancient species scattered."

　　 "Then you have to be careful~"

　　 "Hmm~"

　　 "......"

　　............................

　　Chu Chen naturally did not go straight.

　　 Instead, they took out some anti-inflammatory drugs and gave them to the mermaids. They also gave them a lot of iodophors that can be used for disinfection, and taught them how to use them.

　　 Now, since the ancient species has retreated, the injured mermaids can go to the back and look for some coral islands to heal their injuries.

　　For marine creatures, they can recover even if they are injured in the water. After all, ordinary fish have no chance to go ashore.

　　 However, after recovery, the wound is often unsightly, and some functions of the body will also be affected.

　　It doesn't matter to creatures without intelligence.

　　The mermaids are different. They'd better go to the coral island and let the wounds recover in a dry environment.

　　.

　　 The mermaid patriarch is still not at ease with the ancient species, and originally planned to send some uninjured mermaids to guard the gap.

　　 However, this work was taken over by Chu Chen, and Chu Chen asked the five little mermaids to guard the innermost gap, just in case.

　　 In fact, there is not much danger now. According to the past experience of the mermaids in the Coral Sea, after the ancient species retreat on a large scale, they will often never come again.

　　 So, after the mermaid patriarch thanked Chu Chen again, he took the mermaids back to recuperate and healed.

　　 She has an ability, which is also related to healing.

　　 This time, no mermaid died, but many were injured.

　　 There are a few mermaids, but they are still a bit serious, and they need some time to recover.

　　............................

　　 After seeing the mermaids leaving, Chu Chen also took Caiwei and them on the road.

　　 The mermaids have been fighting for so long, it is estimated that it will take some time to recover and rest.

　　 Chu Chen followed back now, it didn't make sense.

　　 It's better to go east and explore.

　　.

　　 "Brother Chu Chen, this trench is really deep~"

　　 Ten minutes later, the whale battleship appeared at the bottom of the trench.

　　This trench is indeed quite deep.

　　 Its depth is comparable to the deepest trench on the planet Earth, which has exceeded 10,000 meters in depth.

　　 10,000 meters, which is ten kilometers!

　　 Throw down the mountain with the highest earth star before crossing, and the distance from the top of the mountain to the sea is more than a thousand meters!

　　At this concentration, on Earth, except for some shrimps, most fish can't get down.

　　 Before Chu Chen crossed, if it was at this depth of water, only some specially made small submarines could go down.

　　 But, this is the island world.

　　 Under the influence of mysterious energy, some of the mermaids in the Coral Sea can come down.

　　 In addition, the navigation technology of this world is higher than that before Chu Chen crossed. If it were other human beings, it could also go down to this depth through some submarines. However, such submarines were quite expensive, and ordinary island owners could not have them.

　　.

　　Other ancient species, I don’t know if they can come down, but the whale battleship that has evolved to level 4 and is about to reach level 5 will have no problems coming down.

　　 Chu Chen estimated that Caiwei and the others are now out of the whale battleship, and there must be no problem.

　　 Chu Chen, who shared a lot of abilities from his own many marine creatures, should have no problem getting out of the whale battleship.

　　 These abilities enable Chu Chen to have a mermaid-like breathing method underwater, which can effectively balance the pressure inside and outside the body, not to mention that Chu Chen's current physical fitness is already terribly strong.

　　The whale battleship is made of seabed gold. Although the water pressure at this depth is terrifying, there is no problem.

　　.........................................

　　The whale battleship traveled along the bottom of the trench.

　　 Chu Chen turned on the light and looked outside.

　　 Such a trench is not uncommon in the island world, and such a trench is not the deepest in the island world.

　　 It is said that some island owners have discovered a trench with a depth of more than 100,000 meters!

　　 One hundred thousand meters, or 100 kilometers, is quite a terrifying distance.

　　 Before crossing, on the highway on the earth and the stars, a normal car ran for an hour, which would be 100 kilometers.

　　 Think about it, how long did you run on the highway at a speed of 100 kilometers per hour for an hour?

　　 But now, a trench in the island world is so deep!

　　No island owner has ever gone down to such a deep trench. I am afraid that the current whale battleship cannot go down. The water pressure is too terrifying. I am afraid that waiting for the sea creatures, there is no way to go down to the bottom.

　　.

　　 "Hey, gold under the sea!"

　　 After exploring this way for some time, Caiwei found a piece of gold under the sea.

　　 "I'll go out~"

　　 Caiwei volunteered.

　　 "Pluck Wei, let me go, your body is not as good as mine."

　　 Little Mermaid Jasmine said.

　　 Soon, they didn't have to fight, because when the whale battleship approached, Shanshan directly used the control ability to get the piece of gold from the sea, and then got it into the water inlet of the whale and the whale.

　　 is very convenient.

　　The whale battleship continued to explore along the bottom of the trench. After exploring for some time, another piece of gold under the sea was discovered.

　　 At the bottom of this trench, there is still a lot of gold under the sea!

　　.

　　 Although the mermaids of the Coral Sea can come down, they may not be able to stay for long. Therefore, the mermaids of the Coral Sea did not explore this trench on a large scale before.

　　 So, Chu Chen asked the Whale Warship to continue exploring.

　　 In this way, after a few hours of exploration, Chu Chen had obtained more than 30 pieces of seabed gold.

　　 "Unexpectedly, there is so much sea gold in this trench."

　　 Chu Chen couldn't help but feel some joy.

Although many, but in fact, the area explored by the whale battleship in these few hours is not small. Its speed on the seabed is greatly affected. It can flow for tens of kilometers in an hour. It is in a "Z" shape along the trench. The constant flow greatly increased Chu Chen's search area.

　　 "Brother Chu Chen, the trench is still very big, so the speed of exploration is too slow, let us go out too~"

　　 The mermaids said.

　　 Chu Chen groaned for a moment, and agreed to let a little mermaid try first, let's talk about whether it can withstand the water pressure.

　　.

　　I still tried Jasmine.

　　 She is also a level 5 mermaid.

　　 Through the special access cabin, Jasmine soon appeared outside the Whale Warship.

After 　　 paused there, Jasmine swam freely in the water!

　　 As expected, no problem!

　　 So, thirty or so mermaids all went out to search for sea gold.

　　The ancient whale floated up again and changed his breath.

　　.........................................

　　 After the mermaids were dispatched, the efficiency was much higher.

　　 In this way, after exploring for a long time, Chu Chen has more than one hundred pieces of seabed gold in his hands.

　　 These submarine golds are mainly dark gold, but also a small amount of virtual gold, and some black gold, crystal gold, and gray gold.

　　 Well, there are some sea gold, named directly after the color.

　　 Black gold has a higher hardness, but its toughness is not good. It needs to be fused with other submarine gold to make an alloy with higher hardness and toughness. On the contrary, it is not as good as dark gold.

　　Gray gold and the like, also have some special effects, which can be used to attack the weapons of the supernatural beings.

　　 Similarly, some submarine gold can also effectively defend against some non-physical abilities attacks.

　　.

　　 There is indeed a lot of seabed gold in this trench.

　　 "Take a break and continue searching~"

　　 Chu Chen said.

　　 The mermaids all returned to the whale battleship to rest.

　　 After a nap, Chu Chen and the mermaids continued to explore the trench.

　　 This exploration took three days.

　　 Of course, Chu Chen left a small number of mermaids on the top of the trench to guard against the re-emergence of ancient species.

　　 However, the ancient species seemed to have completely retreated, and did not reappear.

　　.

　　 In three days, Chu Chen and the mermaids have explored all the areas that can be explored in this trench.
