This trench is quite long, and, the farther south, the deeper, and when it reaches a certain depth, the speed of the whale battleship inside is affected, and the time for air exchange is shortened. After the speed of the mermaids is also affected, Chu Chen Decisively ended the exploration.

　　 There are already several hundred pieces of gold under the sea in his hand, most of which are dark gold.

　　 With so much dark gold, you can create another whale armor.

　　......................

　　 "Go, let's go back to the Coral Sea first."

　　 Chu Chen said.

　　 This time exploring the trench, the harvest was not small. After Chu Chen was going back to the Coral Sea to take a look at the mermaids, he would go to the eastern sea area full of ancient species to explore.

　　 Anyway, the various islands of Chu Chen have been growing and building, and many things are in progress recently. Chu Chen has nothing else to do on Turtle Island.

　　 Soon, the whale battleship appeared in the coral sea again.

　　 "Your Excellency Chu Chen is here~"

　　 Seeing Chu Chen coming over, the mermaids were a little joyful!

　　 gathered around one after another.

　　 "Your Excellency Chu Chen~"

　　 "Your Excellency Chu Chen~"

　　 "......"

　　 The mermaids greeted Chu Chen one after another.

　　 In the battle a few days ago, Chu Chen turned the tide and saved all the mermaids. The mermaids were extremely grateful to Chu Chen.

　　 "Your Excellency Chu Chen, this is the clothes we made specially for you~"

　　 At this time, a little mermaid swam over and handed Chu Chen a beautiful dress.

　　 This dress was made by the mermaids these days, and they used another rarer seabed plant.

　　 In order to find this kind of seabed plant, hundreds of mermaids searched for a long time before they found it.

　　 Then, he made this dress for Chu Chen.

　　 Under the enthusiasm of the mermaids, Chu Chen had to put it on on the spot.

　　 "It fits quite well, I said it is this size!"

　　 A mermaid clapped his hands and watched Chu Chen put on the clothes they made by himself. These mermaids were not too happy to mention them all.

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

　　 Then, surrounded by the mermaids, Chu Chen and Cai Wei came to the palace where the mermaids were discussing matters.

After 　　 arrived, Chu Chen saw that the mermaids had prepared a large number of delicious coral fruits to entertain Chu Chen.

　　 "Your Excellency Chu Chen, please sit down, they want to surprise you~"

　　 The beautiful mermaid patriarch came, said.

"surprise?"

　　 Chu Chen sat down.

　　 Then, he heard a beautiful singing.

　　 Chu Chen saw a mermaid wearing a white veil, singing in the sea in front of him.

　　 She looked at Chu Chen with bright eyes, and she seemed to have a feeling of affection.

　　 Then, more well-dressed mermaids emerged from the water, and they danced beautifully in the water!

　　 Chu Chen knows what the surprise the mermaid patriarch said.

　　 These mermaids, in order to thank Chu Chen, not only prepared delicious coral fruit, but also carefully prepared singing and dancing!

　　 sing and dance to thank Chu Chen!

　　 For the mermaids, this is already quite a high standard of etiquette...

　　 In this world, the only person who can enjoy such treatment is Chu Chen!

have to say.

　　 The mermaids are all beautiful and beautiful, their singing is quite nice, and their voices sound incomparably ethereal, just like nature.

　　 This kind of singing is really intoxicating.

　　 I don’t know how many times it sounds better than those that rely on sound cards to tune out.

　　Chu Chen couldn't help but hear it.

　　.

　　 What attracted Chu Chen more was the dance of the mermaids in the water.

　　 Their dancing posture is quite graceful, combined with their delicate looks, this kind of dance also makes Chu Chen extremely happy to watch.

　　 "Your Excellency Chu Chen, this is their juice specially prepared with coral fruit."

　　 At this time, the mermaid patriarch gave Chu Chen another glass of juice.

　　 Chu Chen took a drink, and immediately felt that it was too delicious.

　　Unexpectedly, the mermaids can still make such delicious juices.

　　 If you look back, you can ask which kinds of coral fruit the mermaids use. If you can drink this kind of juice often, it would be a pleasure.

　　............................

　　 After a full ten minutes, the mermaids finally finished their dance, and the singing stopped, but Chu Chen felt a sense of unfulfilled intentions.

　　 If you are watching some TV programs, a song and dance for more than ten minutes will only make people feel long.

　　 However, Chu Chen now feels that the time is too short.

　　 I haven't appreciated it enough, but it's over.

　　.

　　 "Your Excellency Chu Chen~"

　　 After the dance, a large number of mermaids came around again.

　　 "Your Excellency Chu Chen, this is for you."

　　 At this time, a handsome little mermaid handed a string of beautiful shell bracelets to Chu Chen.

　　 At the beginning of this little mermaid, the other little mermaids followed and gave Chu Chen one by one gifts.

　　Most of these gifts are handmade by them. There are shell bracelets, some beautiful conch, and some necklaces made of colorful stones on the bottom of the sea.

　　 Seeing that these little mermaids were so enthusiastic, Chu Chen couldn't refuse, and accepted them one by one.

　　 In this way, after half an hour, Chu Chen had already received a lot of gifts.

　　 There were a lot of these gifts, and they were a lot, and Chu Chen directly put them into the storage space.

　　These all represent the wishes of the mermaids.

　　 These gifts may not be worth much, but their hearts are priceless, and these mermaids did not spend less time and thought to make these gifts.

　　.

　　 After the Little Mermaid gave gifts one after another, the Mermaid Patriarch also personally gave Chu Chen a gift.

　　 That is a crooked dagger.

　　 This dagger looks quite delicate. The material is probably made of seabed gold, and it should be a kind of seabed gold that Chu Chen hasn't seen yet.

　　 "Your Excellency Chu Chen, I got this dagger by accident. It is very sharp and very good for self-defense. Now, I give it to you."

　　 The mermaid patriarch said.

　　 Chu Chen took the dagger and saw that it was indeed very sharp.

　　 He took out a stainless steel knife and cut it with it.

　　 Suddenly, the stainless steel knife was cut off!

　　 "So sharp."

　　 Chu Chen whispered.

　　 This dagger is a bit sharper than the virtual golden dagger in Caiwei's hand!

　　 The craftsmanship of the virtual gold dagger is not bad.

　　 This shows that the material of this dagger is quite terrible. I don't know what type of seabed gold is made of, or is it made of several kinds of seabed gold alloys?

　　 At present, the use of seabed gold by human island owners is generally based on a single application, and alloys are rarely constructed. This is because seabed gold is too precious to try indiscriminately.

　　 It’s just an alloy after fusing several kinds of undersea finance.

　　 must have proportions, formulas, and formulas.

　　 Not all submarine gold is suitable for alloying.

　　 In this regard, there is currently only one alloy formula for seabed gold.

　　 This alloy formula is not publicly available. If you want to use it, you have to pay for it.

　　.........................

　　 Of course, alloys are not necessarily required. The current dark gold armor is already quite powerful and can withstand ordinary torpedoes.

　　 If you want to blow up such a dark gold armor, it is estimated that a fairly powerful missile can be blasted up.

　　 "Patriarch, this dagger is too precious, I can't take it."

　　 Seeing that this dagger is so sharp, Chu Chen thought for a while, but decided not to take it, leaving it to the Mermaid chief to defend himself.

　　 He has so many abilities now, all kinds of shared talents, and a lot of skills.

　　 There is also the rapid healing ability of sea turtles.

　　 will share the octopus regeneration ability soon.

　　 Chu Chen is already quite powerful, and he can also be called a Xiaoqiang who can't die.

　　 This dagger is obviously more useful to the mermaid patriarch.

　　............

　　 "Your Excellency Chu Chen, this is my heart, please accept it!"

　　 However, the mermaid patriarch was also quite insistent, insisting on giving the dagger to Chu Chen.

　　 After declining like this for a long time, Chu Chen saw that he could not quit, so he had to accept the dagger.

　　 "It is detected that the mermaid patriarch has reached the conditions of a free contract, do you sign a free contract with the mermaid patriarch?"

　　 At this time, the sound of the system suddenly rang.

　　Hey, after accepting this dagger, did the mermaid patriarch actually meet the conditions of a free contract?

　　 And, this time it’s not a group contract.

　　So, after signing a free contract with the mermaid patriarch, can you sign a new group contract with the mermaids in the Coral Sea?

　　 Chu Chen did not hesitate, and chose "Yes".

After 　　 chose "Yes", Chu Chen obtained a contract.

　　.

　　 After obtaining the contract, the next step is to convince the mermaid patriarch.

　　This matter is not difficult.

　　 Because the Mermaid patriarch has already fulfilled the conditions, it shows that her trust in Chu Chen has reached a very high level.

　　 So, Chu Chen called Caiwei and the others. It took some time to show Caiwei their progress after signing the contract to the chief mermaid. Caiwei also gave some persuasion to the chief mermaid.

　　 In this way, ten minutes later, the mermaid patriarch’s contract was successfully signed!
