Mars stared at the water for a moment, and then saw the bone knife in the tub.

Then he took the bone knife in his hand and prepared to replace it.

When the seawater was replaced before, Mars and Ben didn't know where the seawater went.

So I want to be more straightforward about the replacement, and then see what kind of replacement process this thing is.

"Help me replace the bone knife with a steel knife. ”

Mars was very bold and then directly began to use the ability of displacement.

"Please choose to replace in an empty flat area to avoid danger. ”

Mars didn't see a hint that the swap was successful, but instead a place appeared for him to swap for a swap.

Only in such a place can the replacement be carried out without any problems.

Mars glanced at the platform he had just made.

Then put the bone knife on it.

As Mars began to replace again, a bone knife vanished out of thin air in an instant.

Mars felt as if he hadn't seen clearly, and rubbed his eyes with his hand, and when he looked again, there was a metal knife on the slate.

This knife can be seen as a blade.

"Is it that fast?"

Mars looked at the time to rub his eyes, and the replacement was completed. Then carefully pick up the stainless steel knife.

The blade of this knife is very sharp, you must know that it is steel, not ordinary iron.

So this thing should be said to be a very rare thing in this world.

The only thing is that it's a little too small.

"The first tool replacement, get 0.3 attribute points!"

"Mars Morley – Constitution: 1.3, Stamina: 0.8; Remaining attribute points 1.1!"

After the replacement was successful, the knife was held by Mars, and then a new reminder was seen.

"Are there so many stat points already?"

Mars looked at the remaining implementation points, and then at his own basic attributes.

Then his eyes were fixed on his constitution.

This is the only thing that can be increased permanently, and it is to completely change one's physical strength and various comprehensive attributes.

So, he felt that he should make some choices at this time.

"A normal adult's physique is 1.5, and I'm about to become an adult now, so let my physique reach the standard of a normal person first, so that I can help my father do more things. ”

Mars thought so, and then made up his mind.

This should be the second time he has added points himself.

The first time it was a temptation, but this time I knew my goal.

So Mars directly added points to 1.5 on his physique.

This time, although the addition was successful, Mars found that it did not bring about the explosive increase in power that he did when he added two points for the first time.

However, he could also vaguely feel that his strength was getting stronger.

As for the rest, Mars has not yet had a chance to test.

The attribute points have been added by two points, and the rest of the Mars plan is kept, this sea is too dangerous, so let's just be in case of emergency.

At this time, Mars looked at the knife to see how it could be used.

"You can make it into a spear, it's much easier. ”

Mars looked at the small knife the size of his palm and thought.

However, Mars soon realized that there was nothing needed to make a spear, and if a spear was made out of stone, there was no need for metal to make the tip of the spear.

"It's also a tool to use with you, so it's good to cut meat. ”

Mars wrapped the handle of his knife around some hides so that he wouldn't cut his hand.

Mars, having done this, put the knife aside and waited for his father to catch the food.

A little more time passed, and Lawrence emerged from the water.

His hands were empty.

"Mars, let the island stop, and then you and I go underwater, I think we can make some traps. ”

Although Lawrence is a very good sea citizen, he does not mean that he can catch food every time.

So at this time, after he went into the water and didn't catch food, he had a new plan.

"Okay, father, what do you want me to do?"

Mars stuck the knife in the belt of his clothes and asked his father.

Lawrence thought for a moment and said, "Although the island is moving, it is not moving fast, and I found other food parasitism in some small caves in the reef underwater, so I need your help." ”

"Then there's the trap to make some fishing traps on the reef so that we can get food at any time. ”

Lawrence kind of told all his experience and then came up with a good idea for Mars.

"Father, you're so right, why didn't I think of it? We're going to get traps, and we'll catch a lot of fish. ”

Mars felt that his father had reminded him that he could make some fishing traps, and then go into the water and catch them when he wanted to eat fish.

So he quickly got off the moving island and the two of them dived together.

Lawrence's meaning is very obvious, that is, to make a lot of traps, and then it is convenient to fish.

And Mars also understood what his father meant, so at this time, he knew what to do.

Dive into the location of the reef under the trees.

The moving island has been stopped by Mars, so they don't have to worry about being left here by the island.

Lawrence is next to Mars.

What to do and where to lay the trap, this is what Mars knows.

Different depths have different foods, and Mars will start to use his own ability according to his father's meaning, and begin to make stones that were originally like sea reefs into cages attached to the reef.

The cage can be opened at will, without the need for Mars to come in person, and the cage will be like a fence so that you can see what's inside.

The whole process was very fast, Lawrence gave his son a gesture, and Mars began to build.

While the two of them go to the surface to breathe, Lawrence tells his son what to do next.

As the clock ticked on, by noon, Mars had dozens of fishing cages underwater, and of course lobsters and the like.

After a morning in the sea, Mars's energy had rapidly declined, and he could only stop for a while at this time.

At noon, they had to hide from the sun, and Mars and his father had to eat some of the dried fish they used to have.

Dried fish with a hard and fishy smell can only be gnawed off little by little.

Neither disgusted nor disgusted, Mars ate it seriously.
