Professor Sun didn't salute like everyone else after seeing Zhao Mubai coming, but first blew his beard and glared at Zhao Mubai to warn him!

"It's okay to show you, but you kid can be careful with me, if I break it, I'll beat you up with this old bone!"

Zhao Mubai looked at Professor Sun with a dumb smile, this old man is really a person of temperament, if he is a bystander, who dares to talk to him like this.

"Professor Sun, don't worry, I definitely won't break it for you," Zhao Mubai could only comfort him in desperation.

"You kid have to talk and count," Professor Sun stared at Zhao Mubai suspiciously, waved his hand, and motioned to his assistant to take out the immortal bird-grade Gauss rifle he had just developed and show it to Zhao Mubai.

After the fiery red Immortal Bird-level Gauss rifle was taken out by the assistant, Zhao Mubai's eyes were straight!

Couldn't wait to take the immortal bird-level Gauss rifle in the assistant's hand, Zhao Mubai's fingers slid lightly, feeling the coldness coming from the gun.

After watching Zhao Mubai carefully play with his research, Sun Lao shook his head and explained to Zhao Mubai with a proud face: "This immortal bird-level Gauss rifle is 0.45 meters long, and at the same time it is the most in line with human dynamics, I also use hedging technology, so that this gun can be applied to any terrain!" ”

The body of the gun is silvery-white and pale red, and the magazine of the conventional rifle has been replaced, and when the portable energy conversion device is developed, Lao Sun almost got the information from Professor Zhang with a dead face like a robber.

A small energy conversion device in the form of a spiral is placed behind the gun, and the Gaussian-like energy mass emitted through the crystal transformation is even more powerful than expected!

What makes Professor Sun even more proud is that through the use of energy conversion devices, crystal nuclei with different properties can emit Gaussian-like energy with the same different properties!

Sun Lao frothed at Zhao Mubai and introduced this major feature, thinking about what it would be like when the enemy was under the impact of thousands of fire-attribute Gaussian energy clusters, and suddenly faced a large number of water-attribute Gaussian energy clusters!

Professor Sun's explanation made Zhao Mubai more and more in love with the samples in his hands, it has been nearly three months since the end came, and the star-level zombies have long been rotten on the street, and the moonlight-level zombies are no longer rare.

And the troops recruited by the system have no way to improve their strength through crystal nuclei, like the silver-level troops led by Darius or Gru, they can also compete with those star-level zombies through training.

But the Terran machine gunners led by William are not good, and the highest they can reach the limit of human beings is the end of it.

In the last days, fists represent everything, and now William and Filip have gradually withdrawn from the core of the gathering place.

Sometimes looking at William who led people to patrol the gathering place, Zhao Mubai even felt a trace of guilt, although William didn't say it, but Zhao Mubai also knew that letting these soldiers who had fought on the front line go to guard the gathering place was even more uncomfortable for them than killing them.

But now with the Immortal Bird-level Gauss rifle, it's different, with this thing, William also has the ability to fight zombies again!

Returning the Immortal Bird-level Gauss rifle to Sun Lao's assistant, Zhao Mubai was now more interested in how powerful this gun was.

"Elder Sun, has the weapon been tested? I wonder how the specific damage falls to the ground? Zhao Mubai said.

"The actual measurement of the power of the weapon was just about to be carried out, and then you kid came" Sun Lao rolled his eyes, his words revealing dissatisfaction.

"That's right, I'll try the power of this gun myself" Zhao Mubai pretended not to see the dissatisfaction in Sun Lao's eyes, but said with great interest.

Sun Lao's eyes widened, and he originally wanted to refute, but when he thought that Zhao Mubai, this kid, might send him more technical drawings in the future, the words that had already come to his lips were forcibly taken back by him.

"You kid can test it yourself if you want to, but you'll have to get me a few more technical drawings like this," Sun Lao said quickly.

"No problem, I'll send you another one after a while" Zhao Mubai agreed very simply, the system will refresh the number of lottery draws every week, and all kinds of silver-level technologies are dazzling, one thing is enough for Old Man Sun to study for half a month.

"Okay, then it's decided, don't regret it!" Old man Sun smiled like a fox who stole fish, for him research has become the whole of his life.

With a wave of his hand, Old Man Sun handed over the Immortal Bird-level Gauss rifle to Zhao Mubai very simply this time, not at all like the appearance of being cautious for fear that he would break it just now.

"Xiao Wang, you go to the laboratory to prepare the experimental materials, and the first test data collection will start immediately!"

"Okay professor, I'll go get ready!" The researcher known as Xiao Wang hurriedly ran to the laboratory with a pile of materials in his arms.

Holding the immortal bird-level Gauss rifle, Zhao Mubai came to the laboratory accompanied by Professor Sun and a group of researchers.

"Professor, all the experimental materials have been prepared!" Xiao Wang pushed his eyes, which were thicker than the bottom of the bottle, and said quickly.

"Okay, everyone is starting to prepare, the first experimental data collection is about to begin" Professor Sun, who has entered the working state, is like a different person.

The first batch of experimental materials was taken out, all of which were steel plates made of high-strength alloys, and they were placed at four positions: 200 meters, 500 meters, 1,000 meters, and 1,500 meters.

The transformed crystals have also been taken out, and the colors of the crystals with different attributes are also different, highlighting the heavy gray-yellow earth attribute crystals, the red crystals that are blazing like magma, and the blue crystals that circulate and transform, all of which are beautiful to look at.

"Xiao Zhao, let's start!" Professor Sun nodded to Zhao Mubai with a cautious face, the Immortal Bird Gauss Rifle was made by him, it can be said that it was his hard work, and the next experiment was related to the success of his own hard work, and he could not be treated sloppily.

Zhao Mubai first put an ordinary crystal block into the thumb-sized transformation port, according to Professor Sun, such a small crystal nucleus was enough for a Gauss rifle to fire a full forty times.

If it is supplied according to the normal army in peacetime, that is to say, only three crystals the size of such a thumb are needed, which can be worth the matching ammunition needed in a conventional battle.

When the entire spiral transformation device begins to rotate slowly, it means that the gun is ready to fire.
