Walking back to the altar, Wan Tiandong touched the stone tablet with his hand, and with a thought, the magic array rose from the altar.

A quaint wooden box twenty centimeters long rose from the middle of the array.

No, isn't it! It's so small, could it be the legendary space equipment! Wan Tiandong chuckled in his heart.

Before he could step forward, the small wooden box opened automatically.

There are more than a dozen sparkling spars inside, each of which is the size of a child's fist and has a different color.

It's the heart of energy.

In nature, when the elemental energy is condensed to a certain extent, it will produce energy crystals - energy hearts, which can be used to refine weapons, build special buildings, and are one of the necessary materials for shipbuilding.

These are all rare high-quality energy hearts that the Golden Spring Holy Monarch specially left to him.

What about the good treasures of the Holy Monarch, wouldn't that be these? Wan Tiandong was disappointed.

Wan Tiandong closed his eyes and sorted out the information he had just gotten.

Sure enough, the Golden Spring Holy Monarch hid the real hidden treasure in a mysterious sea area. The map was sealed in Wan Tiandong's mind, and only when his strength reached a certain stage could he be unsealed and had the ability to take it.

There are still tests, there is a master's demeanor, Wan Tiandong breathed a sigh of relief, it is better than nothing, anyway, sooner or later it will be his.

Among the messages sent to him by the Golden Spring Saint Monarch is important information for the construction of the basic energy buildings of the Ocean Territory, including: Territory Altar, Magic Energy Pool, Energy Turret, Protective Tower, Warehouse, and Induction Tower.

In the world of the Endless Sea, there are various energy buildings with magical functions, which are also divided into nine classes.

In this ship, the basic energy building has been well preserved, but the grade has been reduced and it has become inaccessible, and the main body of the building has been reduced to a black iron rank.

It doesn't reach the worst situation, at least the main body of the basic building, don't bother with Wan Tiandong, you just need to reactivate it with the heart of energy.

The Lord's Altar is the core hub of the Sea Domain, equivalent to the heart of the Sea Domain, and is the most important and mysterious of all the building units of the Sea Domain.

The magic energy pool is the elemental pool, which can absorb external elemental energy through the rune array, and is the energy center of the ocean territory.

The energy turret is two pitch-black wooden towers that stand on the fore and aft decks, and can fire energy cannons to attack incoming enemies.

The small blue tower on the top of the ship is the protective tower, which can be arranged with protective formations to protect the ship from damage.

The sensing tower is the guiding light of the maritime territory, which can identify the direction according to the nautical chart and sense a certain range of islands.

Warehouses are used to store food and supplies.

These are the six basic buildings of the maritime territory, and all of them are indispensable.

To become a Sea Lord and become a Black Iron Professional, you must have a Black Iron level territory.

The Sea Lord's territory is his contracted ship and its base energy building units.

Basic Energy Buildings in the Ocean Realm: Territory Altars, Magic Energy Pools, Energy Turrets, Protective Towers, Warehouses, and Induction Towers.

It needs to be upgraded to a Black Iron level energy building.

The construction of each Black Iron Base Building requires a Heart of Black Iron Energy and other magical materials.

In addition, the functions of basic buildings built with different energy hearts are very different.

The foundation building is of the black iron level when it is completed, and of course, there are very few special cases.

Except for the Lord's Altar, each promotion must have a corresponding Energy Heart, and all other basic buildings to advance to Bronze or higher levels no longer require Energy Hearts, only the corresponding magic materials, and the level can be increased through the Soul Melter.

Wan Tiandong's ship, the grade is not in the grade, and the main body of the basic energy building on the ship has degenerated to the black iron level, which needs to be reactivated by a new energy heart.

Wan Tiandong has been hesitant to distribute his energy heart, and has repeatedly discussed with Ke Qiongji and Qianhu, but has not made a final decision.

"You decide for yourself, I don't care, it's your own business!" Ke Qiongji said angrily, and turned to leave.

It's no wonder that Ke Qiongji is so hot, Wan Tiandong has been hesitating, looking ahead and backwards, and he can't pay attention to it.

Wan Tiandong looks at Qianhu and Fluttershy.

The giant man kept wiping his beloved giant axe, completely unfocused on the conversation he had just had.

The little girl was dealing with fruit as tall as hers, and she was covered in juice.

Wan Tiandong was speechless, these two people couldn't count on it at all.

It took a long time for Wan Tiandong to have a clear idea.

"Fluttershy, use this to upgrade your lord's altar!"

Wan Tiandong took out a heart of water attribute energy.

From memory, I know that the same level of energy heart is divided into three levels: low, medium, and high according to the different effects produced.

And this water attribute energy heart was brought back from the Ghost Sea by the Golden Spring Holy Monarch, and it is the energy crystallization of the Ghost River, and it is the best in the high level of black iron, only the rare energy heart such as the Divine Stone is a little bit worse.

You must know that every time the Lord Altar is upgraded, it needs the corresponding level of Energy Heart, and once the attribute is determined, it cannot be changed.

Ninety-nine percent of the area of this world is water, and the heart of energy that is born of the water attribute should be the most and the best.

The little girl held the heart of energy, and in the blink of an eye, the heart of energy disappeared.

The lord's altar and the territory monument above, the formation pattern shone, and black energy gushed out, impregnating the entire ship.

After a few moments, the lord's altar and stele emitted a faint black light.

This also meant that the Lord's Altar became a Black Iron building unit.

Wan Tiandong rushed to the altar, eager to know what kind of natural ability his lord ship would have.

Whether it's a human or a beast, or something else, once you step on the Black Iron Stage, you will gain innate abilities, which is the rule of the world.

Fluttershy is on her heels, faster, and stumbles into the Territory Monument first.

The Spectral Light Barrier consumes a certain amount of magic energy, and a transparent barrier is generated around the ship, and everything in the barrier will be invisible.

The ships in the Spectral Light Enchantment, as well as the people on them, cannot be detected by the outside world, whether they are figures or voices, which is equivalent to overall invisibility.

Any ability has its ability limit, and when it is black iron, the glow enchantment will not be detected by other black iron-level abilities, but bronze and above are not necessarily.

Sure enough, it was this ability, and the Golden Spring Saint Monarch guessed that it was really right.

The energy crystals of the River of Ghosts are rarely obtained, but speculation about them has never stopped. It's a pity that when the Jinquan Holy Monarch got it, the ship was already a holy rank, and no new energy building was built after that, so it has been retained, and it is cheaper than Wan Tiandong.

"How's it going, what kind of talent does the ship produce?" asked Ke Qiongji as soon as she entered, the movement just now alarmed her.

"It's the Light Enchantment---!"

Wang Tiandong explained the talent, with a smug smile on his face.

"It's better to quickly raise yourself to the black iron level, otherwise, you will have to gasp even when you go up the stairs!"

Wan Tiandong breathed a deep sigh of relief, not knowing as much as this little girl.

"Fluttershy, activate the magic energy pool!" Wan Tiandong handed over a heart of dark blue energy.

This is the Heart of Energy generated by the Deep Sea Magic Stone Vein, which has a variety of properties and is best used to build a Magic Energy Pool.

Wan Tiandong's deep-sea magic stone mine is produced from a water low of tens of thousands of meters. Among them, the water attribute accounts for 89%, the dark attribute accounts for 4%, the earth attribute accounts for 4%, and the other miscellaneous attributes account for 3%, and the built magic energy pool will also absorb external elemental energy according to this ratio.

Of course, the energy between different attributes can be converted, but there is a certain amount of loss.

The heart of energy flickered, entered the pool of magic energy in the bottom warehouse, and completely merged into it.

After a spell frenzy, the magic energy pool was upgraded to the black iron level and began to slowly absorb the elemental energy in the air.

Next, Wan Tiandong raised the warehouse, energy turret, protection tower, and induction tower to the black iron rank.

The warehouse uses Ice Crystal Energy Hearts to improve the ability to keep food fresh and prevent food from spoiling.

The energy turret is the strongest attack method on the ship, and Wan Tiandong chooses the energy heart of the thunder attribute and the wind attribute.

The energy of the thunder attribute is the most violent, and Wan Tiandong set the energy turret on the back deck to the thunder attribute, which can release the thunder cannon.

Setting the Bow Energy Cannon to the Wind attribute will give out the Spiral Wind Cannon.

The tower is fused with another heart of water-attribute energy, which activates the formation pattern and generates a black iron-level wave guardian array with the ability to rebound elemental attacks.

The Induction Tower is joined by the Magnetic Stone, a crystallization of energy produced by the intersection of magnetic forces that condense to the extreme, and is the only heart of energy that can build the Induction Tower.

Looking at the new boat, the three of them were sincerely happy.

Finally, there is a place where I can live in peace.

Fluttershy emerges from the Lord's Monument and becomes much more solid.

This is not the end, the three of them looked at Wan Tiandong expectantly, and the next thing is the most critical.

Sure enough, it won't be that simple.

Thinking of the second condition, Wan Tiandong had a headache.

The Lord of the Sea follows the ancient knightly path.

In ancient times, knights followed the ancient knightly path and dedicated everything to the lord, who spent his life fighting for the lord, who bestowed the knight glory, money, land, and even his own surname.

This part of the knights was called the Knights of Bong'en and was extremely loyal to the lord.

And the sea lord does not need a lord, as a price must be followed by a servant, and the first servant must be a knight of grace.

Wan Tiandong unconsciously moved his ears, and his brows were twisted together.

Glimpsing Qianhu who was looking at him from the side, his heart moved, if he wants to say that he is eligible, the most likely one should be him.

"Qianhu, do you --- willing to follow me for the rest of your life?" Wan Tiandong hesitated for a moment and asked solemnly.

"Young master, I have followed you all my life!" replied with a thousand tiger urns without hesitation.

"Then come here! Come up to the lord's altar!" Wan Tiandong was not surprised, Qianhu had always behaved like this.

The two stood on the altar of the lord, stood opposite each other, and put their hands on the lord's tablet.

"The fountain of oath is above, and I, Qianhu, am willing to become a servant of Wan Tiandong, follow him all my life, and overcome obstacles for him. ”

Qianhu suddenly knelt on one knee and read the words of the contract aloud according to the contract process shown on the stone tablet.

"The Fountain of Oath is above, and I agree with Qianhu to become my servant!"

Wan Tiandong put his sword on Qianhu's shoulder, and responded to the road.

A special wave of energy emerged between the two, forming a contract rune array, and the magic power was transmitted between the two. A sight penetrated from the sky, passing through the two of them, Wan Tiandong and Qianhu felt that they had been seen through their bodies.

This special state came and went quickly, and in an instant, an imprint was born in the sea of knowledge between the two, and the contract was reached.

A nascent sail pattern appears on the back of a thousand tigers' hands.

Wan Tiandong helped Qianhufu up and patted him on the shoulder with relief.

Wan Tiandong was lucky, at the moment when the contract was generated, Wan Tiandong sensed that he met the conditions for becoming the Black Iron Lord, and Qianhu's loyalty to him was really good.
