Subsequently, Tu Hao looked at the energy points required to exchange the huàn silver bullet, 20 energy points, "It's so expensive!" However, soon Tu Hao found that these 20 energy points were exchanged for huàn not for one shot but for a full 20 silver bullets, with an average of 1 energy point and 1 shot, of course, if you exchange huàn, you can only exchange 20 rounds for it, not just sell.

After looking at his remaining energy points, Tu Hao did not immediately exchange huàn, but left the ammunition depot, Tu Hao was going to go to see the situation of the heavy firearms depot and the mechanical depot first, and finally decided the cost of the energy points, after all, there are not many energy points, and Tu Hao can only use good steel on the blade.

"Tick!"

Coming to the heavy firearms storehouse, Tu Hao put his hand on the screen on the side of the door, accompanied by a soft sound, the closed door of the heavy firearms store slowly opened, seeing this, Tu Hao walked in with excitement in his arms. Based on Tuhao's knowledge of the game, almost every one of these heavy firearms is a mass killing weapon.

Step into the heavy firearms store, the huge warehouse, there is only one shelf, of course, this is not the point, the point is the dazzling multi-barreled machine gun that sits on the shelf.

"This is the big killer." Tu Hao rushed to the shelf with an arrow step, stroking the multi-barreled machine gun, and there was a sign hanging under the machine gun.

M-137 Grimm: 10 rounds per second, barrel cools for 3 seconds per 1 minute of use.

10 rounds a second, 600 rounds a minute, compared to the legendary Gatling machine gun with up to 6,000 rounds a minute, the M-137 Grimm machine gun has a rate of fire of only one-tenth, but Tuhao feels that this Grimm machine gun should not be so simple.

Sure enough, after asking Zero, Tuhao finally understood the awesomeness of this M-137 Grimm machine gun with a low rate of fire, first of all, it can adapt to all kinds of pistol cartridges, rifle cartridges and machine gun cartridges, and the compatibility is definitely incomparable to the Gatling gun.

There is also the fact that the failure rate is absolutely zero, and the wear rate is almost zero, even if it is broken, Tuhao can repair it as long as it costs some energy points.

In addition, this M-137 Grimm machine gun does not need to be exchanged for huàn energy points, and can be used directly. This is undoubtedly a huge surprise for Tu Hao, who does not have many energy points.

"Up!"

After learning that the M-137 Green machine gun does not need energy points, Tu Hao picked up the machine gun placed on the shelf in a hurry, who knows, the weight of the Green machine gun was somewhat unexpected by Tu Hao, and he couldn't pick it up for the first time, and finally, in the case of Tu Hao's best efforts, this Green machine gun was lifted.

Such a heavy Grimm machine gun, Tu Hao estimates that when using it, his movement speed will become very slow, or even unable to move, of course, under the powerful fire of the Grimm machine gun, the movement speed is not the most important, after all, the use of this Grimm machine gun is fire suppression, and the enemy who is pressed cannot fight back.

As for the ammunition for this Grimm machine gun, Tu Hao didn't dare to use the power of energy bullets, 600 rounds a minute, Tu Hao couldn't afford to use it, it just so happened that Tu Hao still had 10,000 rounds of pistol ammunition in the base, which could be pressed into a chain through the guò ammunition depot to provide ammunition for the Grimm machine gun.

Putting the Grimm machine gun back on the shelf, Tu Hao left the heavy firearms arsenal with satisfaction, it can be said that with this Grimm machine gun, Tu Hao's firepower has increased greatly.

With excitement, Tu Hao came to the mechanical depot, which, like the heavy firearms depot, was also a mysterious place that Tu Hao had never opened.

"Tick!"

Reaching out and pressing on the screen next to the door of the mechanical hangar, with a crisp sound, the door of the mechanical hangar slowly opened in Tuhao's expectation.

Entering the machinery library,The first thing that catches Tu Hao's eyes is a huge machine like an assembly line,Carefully look at this machine,Tu Hao also didn't see the reason,However,Tu Hao saw an operation page on this machine。

It's said to be an operation page, but it's actually similar to the vending machine in the ammunition depot, and there is only one lonely icon on the page that looks like a small machine, and there is also a touch button for manufacturing options under this icon.

RX-78 Chaser: Set up the RX-78 Chaser, a self-destructing machine that tracks the enemy and then explodes and deals damage to nearby enemies, giving additional lethality to buildings.

"Haha, it's actually the RX-78 Chaser, not bad!" Looking at the introduction of this small machine qì person on the page, Tu Hao couldn't help but be overjoyed, it can automatically track the enemy's self-detonating machine qì person, this is definitely another big killing weapon.

However, the price of the same RX-78 Chaser is also at the killer level, and one costs a full 50 energy points, but even if it is expensive, Tu Hao still gritted his teeth and clicked on the manufacturing button on the page.

As Tu Hao clicked the manufacturing button, suddenly, the huge machine like an assembly line began to operate, and after a while, a small square machine with a clockwork key behind the size of a large-screen smartphone was sent out from the conveyor belt of the assembly-line machine.

Picking up the small machine from the conveyor belt, Tu Hao found that although the small machine was small, it was quite fine, with a dull square face, two tracks were legs, and even two small arms on the small machine.

As for the use of this small machine, there is no need for anyone to tell him, Tu Hao also knows, as long as he twists the clockwork behind the small machine.

"Well, if only it could be cheaper." Putting down the small machine in his hand, Tu Hao couldn't help but sigh and said. If the cost of this RX-78 pursuer is cheaper, then Tu Hao's idea of forming a self-detonating aircraft can be realized.

Leaving the mechanical depot, Tu Hao returned to the ammunition depot, and spent 20 energy points to exchange 20 silver bullets, just filled a pistol magazine, and at the same time, Tu Hao also suppressed the nearly 10,000 pistol bullets into a long chain of bullets ready to be used by the Grimm machine gun, at this time, the 260 points of energy obtained by Tu Hao's ghost-faced spider mother crystal nucleus are now only 100 points, 50 points for the RX-78 pursuer, 20 points for the silver bullet, plus 50 points for the 5 floating bullets that Tu Hao used to huàn before, 400 energy bullets cost 40 points, for a total of 160 energy points.

At first glance, Tu Hao used 160 energy points to exchange a lot of things, but if this is a tricky battle, these things can be consumed in an instant.

Fortunately, Tu Hao sniped an F-class sickle mantis just now, and contributed 110 energy points to Tu Hao after absorbing its crystal nucleus, so the energy points at Tu Hao's disposal at this moment are 210 points, as for why the same sickle mantis, but the energy points contributed by its crystal nucleus will be different, Tu Hao thinks that this should belong to the individual's strength gap.

After leaving all the things that he had received, Tu Hao left the base, and the things in the base, Tu Hao could take them out at any time through the guò tactical watch, so Tu Hao didn't have to take it with him.
