[Level 2 water collector upgrade drawing: Level 2 item, which produces 10-20 liters of water every 24 hours after being placed, and will change according to the local environment.]

[Manufacturing materials: One level 1 water collector, 8 units of metal ingots, 4 units of metal parts, and 4 units of glass.]

It’s worth it.

After looking at the data on the level 2 water collector and looking at Su Mu's conditions, Zhang Tuohai felt that the deal was still worth it.

He has no shortage of production materials, and the most valuable thing among them is the 4 units of glass. However, he has exchanged a lot of them in the past two days, so there is no shortage of them.

You can also give the other party chili sauce. He has so much food, so he doesn’t necessarily need chili sauce.

Although I agreed to supply the other party with domestic water every day after the transaction, it is still very profitable after calculation.

The normal amount of water a person drinks every day is about 1 liter.

Even if the two sisters are given 2 liters of water per day and the water collector produces 10 liters of water per day, it is equivalent to earning 8 liters of water per day.

Now, in the regional channel, 200 ml of water can be exchanged for 3-10 units of level 1 resources.

Level 2 resources can also be exchanged for 1 to 2 units.

A bottle of Lao Gan Ma can probably get 500-1000 ml of water.

In other words, his output in one day is enough to offset these expenses, and he is even rich.

This is a huge profit.

After settling the account clearly in his mind, Zhang Tuohai immediately agreed to the deal and got the water collector upgrade blueprint in his hand.

Then the water collector was directly upgraded to level 2.

If the level 1 water collector is only as big as an ordinary water cup, the level 2 water collector is like a beer keg.

There is a pure metal bucket with a faucet next to it and a water pressure mark on the side wall, which indicates how much water is left in the water collector at the moment.

"It's very convenient." After playing with the level 2 water collector for a while, Zhang Tuohai was very satisfied.

He has another way to make money, which is to sell water resources.

In this hellish place, you might be able to survive for two days without food, but without water, you might die from dehydration in just one day.

At least until everyone has a stable way to obtain water, this business can continue.

After putting the water collector in place, Zhang Tuohai sat on his seat to recharge his energy, quietly waiting for the brave man's challenge to come.

After several days of brutal screening, there are not many players who dare to participate in the challenge of the brave.

Except for some players who are extremely confident in their own abilities, the rest of the players who are still participating in the challenge are desperate.

If there is any other way, I will not participate in this narrow escape challenge.

Each challenge involves nearly 50% to 60% casualties. Who can withstand this?

However, the challenge of the brave man is a life-threatening talisman for others, but it is a rare opportunity for Zhang Tuohai.

Just point to this challenge every day to increase your income.

The hour hand and minute hand coincide, and it is twelve o'clock at noon.

Game system reminds: Today the challenge of the brave officially begins.

Zhang Tuohai hung up the hand crossbow, put on stab-proof clothing, carried a skinning knife and a bright flashlight in his waist, and walked out of the car with a hunting spear in his hand.

The scorching sun shone on him, and within a short while, Zhang Tuohai's clothes were soaked with sweat.

"With this damn weather, I don't know when we can get out of this desert." Zhang Tuohai frowned and asked in a low voice, "Which way is it better for the system to go?"

[It is recommended to turn 60 degrees to the left and go forward 2000 meters, where the materials are the most abundant.]

"There seems to be a piece of yellow sand there, and there is nothing there?" Zhang Tuohai glanced in the direction pointed by the prompt system. There was a piece of flat yellow sand over there, and there was nothing.

However, out of trust in the system, Zhang Tuohai decided to follow the direction pointed by the system to investigate.

Although he has entered the desert several times, Zhang Tuohai is still not used to walking in the desert.

After taking a few steps, his shoes were filled with sand. This feeling made Zhang Tuohai very uncomfortable.

Using a hunting spear as a crutch, Zhang Tuohai walked slowly in the desert.

There are no obvious reference objects in the desert, but with the correction of the prompt system, Zhang Tuohai will not lose his way.

Just when Zhang Tuohai felt a little tired and was about to take a rest, suddenly a burst of chirping sounded in the sky.

Zhang Tuohai looked up and saw that a giant eagle was constantly circling in the sky, seemingly staring at him.

This giant eagle has a wingspan of at least four meters and looks extremely majestic. Even at high altitude, Zhang Tuohai can feel that this thing is difficult to deal with.

"You flat-haired beast, why are you calling me nonsense? I'll knock you down sooner or later and make soup for you!"

Zhang Tuohai said angrily.

The giant eagle seemed to sense Zhang Tuohai's dissatisfaction, and actually swooped down from high altitude and rushed towards Zhang Tuohai.

The giant eagle was extremely fast, and in the blink of an eye it jumped in front of Zhang Tuohai from a height of several hundred meters.

The giant eagle stretched out its legs and grabbed Zhang Tuohai.

The giant eagle's nails are very sharp, seven or eight centimeters long, thicker than Zhang Tuohai's thumb. The nails are extremely sharp and shimmer with a cold light.

Zhang Tuohai estimates that if he is caught by the giant eagle, at least a large piece of his flesh will be torn off.

The speed of the giant eagle was too fast. At this time, it was impossible for Zhang Tuohai to fight back with his crossbow and hunting spear.

"What should I do?" Zhang Tuohai faced such a life-and-death moment for the first time, and couldn't help feeling a little panicked.

[Hold the spear in front of your chest and don’t make unnecessary movements.]

The prompt system gives a prompt instantly.

At this time, Zhang Tuohai could no longer think too much, and his body instinctively completed the action according to the prompt system's requirements.

He held his hunting spear across his chest.

Click!

The hard spear shaft was broken as soon as it came into contact with the giant eagle's claws, and the giant eagle's claws continued to grab Zhang Tuohai without losing momentum.

Zhang Tuohai fell backwards with the huge force from the hunting spear, and his whole body fell in the desert.

Looking at the giant eagle's claws getting closer and closer, Zhang Tuohai felt like he was falling into an ice cave.

"Am I going to die here?"

However, before Zhang Tuohai could think about it, his body went limp again.

His body fell downward again.

With a bang, Zhang Tuohai's body fell on a soft place. Although it hurt a little, he didn't suffer any injuries.

Zhang Tuohai looked around and saw that this was a dark place with little light around it.

Just when Zhang Tuohai was about to take out the bright flashlight on his waist to check, suddenly there was another sound.

A huge thing smashed down from above and landed right in front of Zhang Tuohai.

"What?"

Zhang Tuohai curiously turned on the bright flashlight.

"It turns out to be you!"

Zhang Tuohai was happy to see the true appearance of the fallen thing.

What fell was none other than the giant eagle chasing Zhang Tuohai.
