On the lid above the case, there is a screen.

On the screen is an exchange menu.

There is only one item that can be redeemed.

A knife.

A knife with a very ordinary shape.

However, the exchange price reached 200,000 points of time index!

It is twenty times the price of this alloy hammer in Li Teng's hand!

From the outside of the picture, it is impossible to see what is good about this knife, but the color of the metal looks slightly darker than Li Teng's mace.

The number of 200,000 means that Li Teng has to kill at least 200 giant rats, or 40 bear rhinos, to earn so many time indexes.

This also hooked Li Teng's curiosity.

How strong is this knife to be worth the price?

Now Li Teng, the time index balance in his account is only more than 60,000, and if he wants to exchange this knife, he has to earn more than 130,000 time indexes.

Converted into giant rats, more than 130 need to be hunted.

Converted into a bear rhino, twenty-seven will also be hunted.

There was a hole in front of the platform, Li Teng hesitated for a moment, returned to the initial place to enter, put on his equipment, picked up the mace and prepared to go to the stone cave in front of him to explore.

The stone slab under his feet didn't move anymore, and it looked like as long as he cleared the level, he didn't have to run again the second time.

After going up to the platform where the treasure chest was located, Li Teng took a few more steps and burrowed into the stone cave in front of him.

After entering, there was a space of about 100 meters in front of it, in which a bear rhinoceros was swimming around.

Without the cover of the white mist, when it turned around and saw Li Teng, it immediately roared and rushed towards Li Teng.

Li Teng immediately brandished the mace and started a battle with it.

After so many days of training in the extreme ability of running, Li Teng's legs are now full of explosive power, moving very fast and flexible, and he easily dodged the collision of the bear rhinoceros, and then smashed a hammer on its side face.

In less than ten minutes, Li Teng easily ended the life of the bear rhino and got the first 5,000 points.

There are two more openings in this space that extend out.

Li Teng chose the hole on the right to enter.

After entering this time, there were two bear rhinos inside.

Without the obstruction of the white mist, the two bear rhinos saw Li Teng almost at the same time, and then rushed towards him at high speed at the same time.

The first time he faced the attack of two bear rhinos at the same time, Li Teng was still a little stunned at first, but after the combat power was deployed, he found that after the strength of his legs was increased and his ability to move was greatly enhanced, facing two bear rhinos at the same time was not as terrifying as he imagined.

As long as he doesn't get hit by them at any time, and doesn't give them a chance to kick, they pose little threat to him.

More than 20 minutes later, there were two more bear rhino corpses on the ground.

In the next stone cave space, there were two bear rhinos roaming in it, and Li Teng became more and more comfortable hunting them, and he could basically control the battle in about twenty minutes.

And you can also ensure that you don't get hurt.

Although the spaces within these caves are connected by openings, they seem to be somewhat restricted.

It's that Li Teng can swim between the holes in these spaces at will, these bears and rhinos don't, they only stay in the space where they are, if Li Teng passes through the hole and goes to other cave spaces during the fight with them, they won't chase after them.

Walking around this labyrinthine stone cave, Li Teng also found a space in the cave without a bear rhinoceros.

Inside is actually a gym.

I searched around the gym but couldn't find the chest.

I found something new inside.

There is an energy drink vending machine next to the wall, and next to the energy drink vending machine, there is also a protein powder drink vending machine.

It's not very expensive, 1000 points a bottle, Li Teng bought a bottle, it's a 2L model, it's very affordable.

If you drink it in one go, you won't be hungry at all.

But it feels boring.

Li Teng left here and continued to hunt the bear rhino.

Before noon, Li Teng still hadn't saved up enough time index of 200,000 points, and he was still short of more than 40,000 points, so he could only continue tomorrow.

……

At the end of the twelve-hour torture, Li Teng returned to the cave and continued to hunt the bear rhinoceros.

Two hours later, Li Teng completed the hunting of nine bear rhinos, accumulating enough time index of 200,000 points.

Extremely excited, he returned to the treasure chest on the platform and exchanged the knife for 200,000 time indexes.

After confirming the exchange, Li Teng opened the lid of the box and took out the physical object of the knife from the box.

As soon as he got it in his hands, Li Teng felt that something was not right.

Although the knife looks light and thin, it is actually very heavy, and the preliminary estimate is about a dozen catties, or even close to twenty catties.

The knife is a good knife, high-tech material, and an incomparably sharp edge.

However, Li Teng wielded it very hard and could not use it normally at all.

Human power is actually very small.

In the fantasy fairytale, the weapons in the hands of those protagonists are set to hundreds of thousands of catties, which has no reference value for ordinary humans.

In history, the double hammer of Li Yuanba, the first good man in the Sui and Tang dynasties, weighed 800 catties, Pei Yuanqing's double hammer weighed 300 catties although it was lighter, and Qin Shubao's gold hammer weighed 60 catties.

Lu Zhishen in "Water Margin" went to the blacksmith shop to play a Zen stick, and he asked for a hundred catties when he opened his mouth. After being questioned by the boss, he said, 'Guan Wang's knife is 82 pounds, so I can't get as good as Guan Wang?' In the end, the boss made him a 62-pound water-mill Zen stick.

Is that all true?

Wrong.

As long as you use your brain a little, you know that it is impossible, lifting 10 kg or 20 kg dumbbells or barbells in the gym, even a well-trained fitness macho cannot move for half an hour continuously.

Even a super strong man like Dwayne Johnson and Tyson is unlikely to hold dumbbells to do various swinging movements continuously, not to mention that the power of heavy cold weapons is much more complex than dumbbells and barbells, which are more likely to cause muscle fatigue and even injury.

Athletes with modern science and technology, rational nutrition, and systematic training cannot hold dozens of pounds of weapons for continuous use, and it is even more impossible for generals who were undernourished and did not have scientific training in ancient times to do so. In the unearthed cultural relics and documents, the heaviest weapons on the battlefield are within 10 catties, which also indirectly proves this.

Ancient people were only mortals, and those weapons of tens or hundreds of catties could only exist in the artistic processing of film and television dramas and dramas, and for normal human beings, twenty catties of weapons were already the limit of human beings.

Therefore, even if Li Teng has trained his ability to run at full speed to the limit and trained the strength of his leg muscles to the limit, he still can't swing this knife as much as he wants.

Not to mention using it to chop giant rats and bear rhinos.

This made Li Teng feel very frustrated.

If he wanted to use this weapon, it would take at least ten days or more to go to that gym to train the strength and muscles of his arms, shoulders, back, chest and abdomen.

200,000 points of time index, it seems to have been spent in vain.
