That night, Mars learned from the sailors about the situation before Arbus and Frank left the merchant ship more than a month ago, and also learned some useful information about the sailors' inquiries during this time.

After synthesizing the information he had received, Mars decided to take a boat to Sunset City overnight, and perhaps to return home, he was a little impatient.

The Tamir River is so abundant and wide that even large ocean-going merchant ships can pass through it, and sailors have been to Sunset City before, so they are familiar with the waterways, and there are not many problems with night sailing.

In addition, the power system of the merchant ship does not rely only on sails, so even if there is no wind, it can still go upstream, and of course, there are no sailors rowing, and there are less than ten sailors in total.

Of course, the power systems of merchant ships from the Barlov world are kept secret in order not to be discovered by the Seven Kingdoms of Humanity and cause unnecessary conflicts.

As for why the Baroff world did not bring magical technology to the Seven Kingdoms of Mankind, Mars has always been unable to figure it out, perhaps until he has enough qualifications, he will know.

The energy source of the ship's power system is the magic stone, the merchant ship has sufficient reserves, and there is no need for Mars to worry, the first mate Pete is responsible for the arrangement, and the sailors take turns to steer.

However, what needs to be worried is the water ghosts in the river and some water monsters.

First mate Pete found a separate cabin for Mars to rest in.

After resting for a while, but Mars couldn't rest assured, so he no longer rested, but was always in meditation, and his mental power was strong, he meditated for a longer time than ordinary magicians, and his perception was much stronger.

Just as Mars was in meditation for less than a minute, the ball suddenly burst out of his chest, emitting a blue light, and it actually activated on its own.

"Inheritor Mars, this goal...... The ball has detected the material breath of the Laps world, and according to Chapter VII of the Supreme Agreement of the Laps Council, the mission system will be forced to start, and the successor will be required to complete the necessary tasks and secondary tasks, may I ask the successor, do you choose to give up, or choose to execute?"

The cold, mechanical sound of the ball reached Mars's ears unmistakably.

After being dormant for so long, you woke up all of a sudden just to start the mission system?

Mars smiled slightly and said, "Qiuqiu, what will happen if you give up?"

Qiuqiu said coldly: "If the inheritor gives up, then he will lose the qualification of the heir, and the special sanction agreement in the eighth chapter of the life agreement will be activated, and part of the inheritor's memory will be erased, and he will lose the inheritance qualification forever, so may I ask the inheritor, do you choose to give up, or choose to execute?"

Mars didn't answer right away, his current mission was to rescue Arbus and Frank, but if he carried out Qiuqiu's mission again, I was afraid that something new would happen.

However, it seems like an incredible thing to clear some of the memories, is it magic or the science and technology of the glory days of Laps?

If you erase some of your memories from the moment you get the Orb of Civilization, wouldn't you be left with nothing again?

Mars took a deep breath, what were you hesitating about at this time, and then said in a deep voice: "Execution!"

Qiuqiu immediately said: "If the inheritor chooses to execute, then the task system will be activated, please ...... later"

Mars didn't think anything else, he wanted to know what the hell this mission system was!

After a while, Qiuqiu said coldly: "The mission system has been activated, the first mission is released, the first task is to establish a defense base, the defense base has a defense index of seven stars, and it can accommodate millions of ...... in the index"

With the introduction of Qiuqiu, Mars also knew what defense base, this base can be called a military city, that is, a fortress city that can accommodate a million troops, as for the defense index, it refers to the fortification of the fortress, the firepower equipment, and the amount of material reserves, which are three comprehensive considerations.

Of course, how to build a defensive base, this is no longer a problem for Mars to consider, after Qiuqiu activated the mission system, it automatically unlocked the extremely unbelievable and huge knowledge of Mars to retrieve the base structure map, fire device map, etc.

Of course, Mars just glanced at it, and he felt a big headache, it took time to eat such a volume of knowledge, so I don't know how much time it would take, would he still be able to cultivate to the Holy Rank?

At the end of the task, the time limit of the task is remarked, and there are only five years!

Build a fortress in five years?

Is this possible?Mars was skeptical, but there was no doubt that this was a must-complete task with a five-star difficulty.

"What will happen if you can't complete this task?" asked Mars.

Qiuqiu paused slightly, and said: "This is a necessary task, that is, it must be completed, and it is also a first-level task, according to Chapter 8 of the Supreme Agreement, the first-level sanctions will be activated, and Qiuqiu will start the self-destruction procedure, and the successor will be killed together!"

“......”

Mars didn't know what to say, but it can be seen that this task is important, but in any case, since you have chosen to carry it out, then do your best!

Mars then asks about many details of the mission, such as whether it can be commissioned to build it, what happens if the heir dies within five years, and so on.

It wasn't until Qiuqiu ran out of energy and fell into hibernation that Mars stopped asking.

At this time, it was already late at night, and only the "whoosh" sound of the merchant ship breaking the waves was heard.

Mars stepped out of the cabin and went to the deck, where he saw the first mate controlling the rudder, and after greeting him, he went to the side of the ship and looked out over the Tamir River.

The source of the Tamir River is in the Olgaard Plateau, near the Kingdom of Eternal Winter in the north, where there is an ice field from which thousands of rivers flow, and finally in the northern plains province to become a large river.

The people of the Sunset Kingdom call it the "Heavenly River", and this river not only nourishes most of Sunset City's land, but also becomes Sunset City's economic lifeline to Angela.

However, when the Tianhe River entered the Tamir Plain, it was called the "Tamir River", which was the name of the river given by the first king of Angela.

It's just that at this time, the crescent moon is in the sky, the stars are dotted, the earth is dark, and it is impossible to see how many things are clear, and everything seems so lonely, which makes people feel a sense of loneliness, like this night shrouded Mars's heart.

"Whoa!"

A water ghost jumped out of the water and swooped down on Mars.

Mars snorted coldly, the magic power of his hands surged, and the detention magic was released instantly, and the water ghost was frozen in mid-air, and then in a burst of piercing wails, it was crushed into a ball of flesh, and with a "poof", it fell into the water.

The wail of the water ghost woke many sailors, but when the sailors rushed out of the cabin, Mars laughed: "It's just a water ghost, it's been dealt with, you continue to rest, I will keep vigil for you!"

The sailors couldn't help but look shocked on their faces, just a little time to dispose of a water ghost? Is this still the Highness Mars they knew?

However, seeing Mars smiling so easily, they could only thank each other, and then entered the cabin to continue resting.

Pete, the first mate at the helm not far away, smiled "hehe", stretched out a thumbs up to Mars, and continued to take the helm, looking at his expression, he was also very nervous.

Although there are no reefs in the inland waterways, there are monsters in the water, some of which will cause a whirlpool and make it easy for merchant ships to roll over, so Pete needs to pay attention at all times to be prepared to deal with it with all his might.

Mars smiled back, and continued to stand on the side of the ship, waiting for the next water ghost to jump on deck, he didn't have to sleep tonight.
