Ding Xiu had no room to think about it, his instinct had already made his brain make arrangements to activate the war paint.

The alloy knife slashed past his eyes, and the light of the knife pressed against his nose, causing him to break out in a cold sweat.

"Ding Xiu, don't be careless, take this as a real battle." Chen Jianing shouted at him, and the offensive did not stop.

"Got it." Ding Xiu raised his shield to hold Chen Jianing's alloy knife, and his steps took half a step back.

The platform of the virtual proving ground simulates a desert environment, which makes the feeling of Ding's feet touching the ground very realistic. The gravel has a poor load-bearing capacity, so he lost his center of gravity a little after he hastily engaged.

There is no sand under the feet of the two of them, but the ground of the platform is simulated by the material and technical conditions, but it is no different from the real sand.

The alloy sword and shield sparked in the collision, and Ding Xiu had already made two moves with Chen Jianing in the blink of an eye, which made him have a great change in his opinion of the girl.

Chen Jianing in Ding Xiu's eyes was once just a soft and weak girl, she was extremely smart, and a pair of skillful hands could make many incredible things.

Now this girl is completely different from Ding Xiu's previous impression, she wears an exoskeleton individual armor that simulates actual combat, as if she has completely changed as a person.

Chen Jianing's shot was very decisive and fast, and there was still a little weak appearance.

As soon as the alloy knife was blocked by Ding Xiu with a shield, two multi-barreled machine guns immediately stretched out from Chen Jianing's back, and when the tongue of fire from the muzzle spitted towards Ding Xiu from the gap that the shield could not protect, the picture in front of Ding Xiu's eyes turned a blood-red.

"You're dead."

Ding Xiu, who was wearing a helmet, saw the line of words that appeared in front of him, and he already knew in his heart that he had lost.

"The battle time is four and two seconds...... Chen Jianing took off his helmet and walked to the screen on the instrument next to him to check the results, "Forty-six bullets were in the body, and the head was hit by the bullet." ”

"It's dead." Ding Xiu's expression was a little embarrassed: "I didn't expect you to be so powerful......"

"You were careless." Chen Jianing glanced up at him, and then continued to check the data recorded in the instrument and record it.

"When you parried the alloy knife with your shield, I felt like you were only taking a small step back, and your center of gravity was still steady." Chen Jianing recorded the data, and discussed the details of the battle with Ding Xiu just now, "What is your perspective?" ”

"To be honest, it was a bit hasty, and I was really careless and didn't analyze the battlefield environment. In fact, the desert is a terrain that I am familiar with, and perhaps it is because I am so familiar that I don't take it seriously. Ding Xiu thought for a while, and continued: "The force of your chopping with the help of momentum is very large, and the moment the shield surface is forced, the sand and gravel on the soles of my feet should have a problem with the load-bearing, so I almost lost my center of gravity. However, I feel that the flexibility of the knee joint of the armor can be improved a little more...... I mean, when I was doing knee bends, that part of the body caused me to move a little slower than I did without armor, which was probably a few tenths of a second, but it didn't allow me to unload effectively. ”

"The joints of the armor are designed according to the maximum flexibility of normal people, ah, I know what the problem is." Chen Jianing slapped her face, and her fingers crackled on the keyboard of the instrument.

"Let's try again according to the situation just now, this time I need to record the data of the force on the shield surface, as well as the whole process of your knee bending and unloading." She recorded the question just now, and excitedly called Ding Xiu to put on the helmet together.

"No problem." Ding Xiu nodded.

The two put on their helmets, and their surroundings changed again.

Chen Jianing, who was dressed in armor, charged, drew his knife, and slashed, all in one go, Ding Xiu was fully prepared this time, and he also moved when the girl moved.

When the left hand raises the shield, the right hand is against the left forearm, the knee of the lower body is bent in advance, and the soles of the feet are inclined against the sand.

There was a crisp sound, and the place where the alloy knife and the shield touched seemed to emit a circle of ripples, making the air next to it distort a little.

The sensation of vibration transmitted from the shield down Ding Xiu's left and right hands, and finally reached the ground and disappeared without a trace.

Ding Xiu relied on the unloading posture just now, and caught the knife steadily, and his body did not move at all.

"Awesome!" Chen Jianing praised.

The multi-barreled machine gun behind her stretched out again, the muzzle of the gun glowing, and the bullets "crackling" like raindrops fell on the alloy shield.

Ding Xiu's reaction was quick and fast, and the power of the war paint made it impossible for any detail of Chen Jianing's movements to escape his eyes.

The timing of the appearance of the multi-barreled machine gun was still just right, but Ding Xiu had already changed the alloy knife in his right hand to parry Chen Jianing's alloy knife, and he moved the shield horizontally, perfectly blocking the gap exposed in front of him.

"Why don't you fight back?" Chen Jianing's several attacks this time were blocked by Ding Xiu, and she showed a few flaws herself, but Ding Xiu did not fight back.

"Am I going to fight back?" Ding Xiu asked.

"Of course, I said it, you have to treat this as a real fight." Chen Jianing nodded.

The two stopped, and she took off her helmet to check and record the data this time.

"How?" Ding Xiu looked at her and asked.

"The problem of flexibility at the armored knee joint you mentioned is real." Chen Jianing's hand was placed on his chin, and as he spoke, he fell into deep thought again.

Ding Xiu saw that she was thinking, so he didn't ask out loud, just stood next to her and looked at her quietly.

"I know why." The girl suddenly raised her head and said, "When we were testing, the tester's personal ability was not up to your level, so the default value for matching this part could not adapt to your fighting style. ”

"I see, doesn't that mean that this exoskeleton individual armor is best tailor-made?" Ding Xiu asked.

"That's the reason, but if it's tailor-made, it won't be able to achieve mass production." The girl nodded, "It seems that the next step is to consider dividing the model into a mass production type and a customized type." ”

"That's a good idea." Ding Xiu praised.

"We have also considered mass production of the six war mechs you saw in the lab earlier, but the manufacturing cost of this heavy mecha is much higher than that of exoskeleton individual armor, and the road to mass production is still far away."

"Are there only six war mechs?" Ding Xiu asked.

"Yes, five of them are Type I and one is Type II. Type I has its own characteristics, and the advantages and disadvantages are also obvious; Type II retains many advantages over the former, while also balancing the disadvantages. Chen Jianing explained a lot of mecha knowledge to Ding Xiu, she was mainly studying these things at this stage, and she also planned to let Ding Xiu assist her in testing.

This kind of military tester is very difficult to find, and there are very few people who are perfectly suitable, and they have to be able to do it well, and preferably without any background.

Ding Xiu fully met these three conditions, so Chen Jianing made an exception to bring him to the research institute to get in touch with these high-tech and high-secret things.

"Let's continue testing." The girl said, "It must be a real battle." ”

She put on her helmet and returned to the stage with Ding Xiu, and the picture in front of them flashed, and it had changed from a desert to a woodland.

"Forest?" Ding Xiu saw the change in the environment, and his heart was clear: "It seems that some new content has been added to this test. ”

In the desert, as long as there are no sandstorms, the view can be said to be very good. But in the forest, it is different, not only is the light dimmer, but there are also many obstacles. Men wearing exoskeleton armor no longer move on the ground inside, and their vision is also quite limited.

Before entering the battlefield environment, Chen Jianing set the distance between the two to 500~1000M random, that is, she and Ding Xiu were in this forest, but there was a distance of half a kilometer to one kilometer in between.

If the other person is not in front of you, then you need to find out.

Chen Jianing is looking for Ding Xiu, and Ding Xiu is also looking for her.

The forest was quiet, and the sunlight shone through the gaps between the leaves, imprinting mottled shadows on Ding Xiu's face. His feet rustled softly on the fallen leaves on the ground, and the feeling of softness was very different from the sand.

Next to the heel, a small dead branch was slightly cocked, and a bird chirped nearby.

Ding Xiu looked intently, listening intently to the movement from that direction.

"It's coming!" After the bird's call, he heard a movement rushing towards him.

The bushes in front of them parted like waves, and a dark shadow rushed out of them.

"What is this?" Ding Xiu was surprised by the shadow that appeared in front of him, it was a beast he had never seen before.

The monster was as big as a small tank, with a pair of long fangs, black fur all over, and a pair of large striking ears on its head.

The monster followed the smell to find Ding Xiu, its nostrils spewing rough air, and its four strong thick hooves lifted a large leaf backwards as it ran.

As soon as Ding Xiu saw its true face, the monster had already rushed to him.

It was fast, but it didn't pose any threat to Ding Xiu, who had activated War Paint.

The monster rushed over, and the fangs went towards Ding Xiu, and after Ding Xiu avoided it, it bullied it in front of it and wanted to bite Ding Xiu's body with its mouth.

"It's so fierce!" Ding Xiu secretly raised his vigilance in his heart.

He dodged the monster's fangs, sideways away from its bloody jaw, and then raised the alloy knife in his hand and slashed at the side of its body.

The blade sliced through its skin and sank into its flesh. The monster let out a long howl in pain, and suddenly became irritable.

Ding Xiu was about to draw the knife, but found that the knife seemed to be sucked into the monster's flesh by a force. This is the monster's muscles tensed in pain, and the knife edge is caught inside.

The first time Ding Xiu didn't draw the knife, he immediately changed his mind, taking advantage of the inconvenience of the monster to turn around, he put both hands against the handle of the knife and pushed it forward.

The blade was submerged in the monster's body, and Ding Xiu couldn't draw the knife, so he chose to stab the knife deeper.
