Soon, the amber stone was sent to Dr. Zhou.

Dr. Zhou picked up the amber stone and squinted at it, it seemed to be an ordinary amber stone on the surface, but the amber stone was not filled with birds, insects, fish, grass branches and leaves, but a small piece of wriggling golden liquid.

"What is this?" Yang Li stepped forward and stared at the liquid sealed in the amber stone, "Could it be mercury?"

"Have you ever seen golden mercury?" Dr. Zhou asked rhetorically.

"I haven't seen it," Yang Li laughed at herself, "I guessed." ”

"How can I look at this thing like a living thing?" Dr. Zhou took off his glasses, his eyes almost touching the amber stone, "Do you see that golden liquid is wriggling?"

"No," Yang Li stepped forward in surprise, "Could it be because your hands are shaking?"

Dr. Zhou carefully handed the amber stone to Yang Li, who looked closer to see it closely.

"Really, it's moving!" Yang Li exclaimed half a minute later.

"How did this amber come from," Dr. Zhou said solemnly, retrieving the amber stone, "Is there any record in the research institute?"

"If you want to find out the origin of this amber stone, you can only go to the database to check Dr. Pan Hua's application and access records for test samples. Yang Li replied.

"Well, you should check it out as soon as possible!" Dr. Zhou instructed, "Dr. Pan's cause of death must be related to it!"

"Yes!"

"As for this amber stone, I'll have to study it myself, and I'll definitely find out!" Dr. Zhou swore as he stared at the golden liquid in the amber.

A few days later, Yang Li found out through Dr. Pan Hua's test sample application record that the amber stone was actually from Qinghe Dungeon, which is now Qinghe Fortress, but Qinghe Fortress no longer belongs to the assets of the Blue Wolf Domain, but belongs to the imperial assets of the two empires of robots and beasts, which are under the direct jurisdiction of the coalition headquarters, and the people of Qiman can no longer enter and exit at will.

"It might be a bit of a hassle now," Dr. Zhou said to himself after learning the origin of the amber stone, "I have to tell the Wolf King myself!"

A week later, Tuguhun had tested more than 3,500 individual performance items of the "Pangolin" and put forward more than 320 suggestions for improvement, and the test progress had exceeded half of the original planned progress, which greatly boosted everyone's morale.

At eight o'clock in the morning of this day, Tuguhun came to the equipment storage room as usual to prepare, he put on the "pangolin" with the assistance of Chunmei and Qiuzhu, and then connected the neuronal system of the "pangolin", after a short coma, he woke up, opened his eyes, and found that Zuo Shishi was standing in front of him with his hands on his chest.

"Testing the Pangolin's defense system today, we had to change places. Zuo Shishi said to Tu Guhun.

"Where?" asked Tu Guhun .

"Yellow Springs Range. Master Zuo replied, and then instructed Qiu Zhu to go and prepare the car immediately.

Soon, Qiuzhu drove a closed anti-gravity ironclad car, everyone boarded the car and sat firmly, the car drove out of the factory, and began to walk through the narrow streets and alleys of the underworld, and the car drove for about an hour before it bumped and slowly stopped.

After getting out of the car, Tuguhun found that this was the bottom of a long, narrow and open abandoned mine pit, the ground was full of potholes, and the air was filled with a choking smell of gunsmoke.

"This is the Huangquan Shooting Range?" said Tugu Hun Qi.

"Yes," Master Zuo said, "all the weapon systems produced in the underworld will be tested here before leaving the factory, and the 'pangolin' test will be arranged these days, and in order to keep it secret, we have cleared all the idle people." ”

"How to measure?" asked Tu Guhun .

"Whew!" Zuo Shishi turned his head to look over there at Nunu not far away, but there was nothing but a dilapidated straight dirt road, "That road, we call it 'Huangquan Road', you have to walk over it after the test starts." ”

"This ......" Tu Gu stared at the dirt road, and for a while.

"You turn off both the camouflage subsystem and the active defense subsystem, and the other unrelated systems should also be turned off," Zuo Shishi ordered, "Test the armor subsystem first today, and the irrelevant system may affect the test effect." ”

"Duck egg, turn off the camouflage subsystem and the active defense subsystem," Tuguhun ordered, "and you turn off the other systems that have little to do with the armor subsystem." ”

The main window of the 16-square grid displays the following information in turn:

Defense System Camouflage Subsystem Down!Status: Complete

Defense System Active Defense Subsystem Shutdown!Status: Completed

......

"Tu Gu Hun , let me reiterate, you can only walk at a normal speed," Zuo Shishi said in an accentuated tone, "You are not allowed to run, you are not allowed to hide, and you are not allowed to stop, understand?"

"Good!" replied Spit.

"Alright, let's get on the road!" said Master Zuo.

"On the road...... That doesn't sound a bit unlucky, my Dr. Zuo!" he spit out his bones and walked towards the dirt road with black lines in his head.

Master Zuo hid his face and smiled.

"There's really no danger ahead, is it?" asked Tu Gu weakly before stepping onto the dirt road.

"No......" Master Zuo stood behind his bones and looked at him with a pitiful look, and couldn't help laughing, "It's weird!"

Spit out the bones and look up to the sky and sigh, the moment is very melancholy.

Tu Gu covered in the shape of a "pangolin" stepped on the "Huangquan Road" alone, the air flow at the bottom of the narrow pit was rapid, and the Tu Gu Hun who switched to normal hearing could hardly hear any other sound except for the whirring wind and his own footsteps, and there was no life and lifelessness all around.

"Xiao Hun, I detected that your heart rate is too fast, and you are very nervous?" said Duck Dan.

"Hehe," he sighed and sighed to soothe his emotions, "you know this......"

"Bah!" A gunshot rang out from somewhere on the right side of the pit wall, and Tu Guhun, who was already on alert, instinctively mobilized the vitality in the acupoints, and the fire dragon vitality that was originally slowly swimming in the acupoints instantly burst out, driving his body to flash dexterously.

"Poof!"

A bullet grazed the spitting body and flew deep into the dirt road, kicking up dust half a meter high.

"Damn!" Zuo Shishi, who was hiding in a bunker 300 meters away and was watching with a telescope, saw it clearly, raised the communication system and scolded loudly: "Tu Gu Hun what are you hiding?

"I'm sorry, I'm sorry!" said through the communication system, "Dr. Zuo, this is my instinctive reaction, and I promise not to do it next time." ”

"Keep walking, don't hide, you're here to be shot today!" Zuo Shishi told the truth in anger, "You are wearing a 'pangolin', the defense index is 2.4, this firepower can't kill you!"

"Okay, okay, okay!" Dr. Zuo," said Tu Guhun as he walked with his hands raised, "I've surrendered, right?"

Sure enough, he was only a few meters away.

"Bah!" another gunshot rang out from the pit wall on the right.

"Whoosh!" A bullet shot at Tu Gu Hun quickly, Tu Gu Hun heard it clearly, and the fire dragon vitality in the acupuncture veins was about to burst out again, but this time he forcibly suppressed the instinctive intention to dodge, and his body stiffened and moved forward.

"Boom!"

The bullet hit the "pangolin" in the chest and was immediately bounced off, leaving not even a single mark on the armor.

Although the bullet did not cause damage to the flesh of the spitting bones, the moment the bullet hit the shell of the "pangolin", the fire dragon vitality was like being taunted by the supreme king trapped in the cage.

"What the hell is going on?" Tu Gu Hun slowed down his pace and looked at the fire dragon vitality in the acupuncture veins, and asked himself, "Could it be that this fire dragon vitality has a special stress response to threats from the outside world?"

"Phew!" This shot came from the left side of the pit wall, and the fire dragon vitality had obediently returned to the qi sea cave to hibernate under the forced suppression of the spitting bone hun, but unexpectedly, this shot sounded like a rebellion against its reverse scales, only to see the fire dragon vitality trapped beast out of the cage like a "boom" instantly got rid of the fetters of the mind, rushed out of the qi sea cave with the momentum of thunder, and passed all the way along the Du vein, connecting the perineum, tail, Sandwich the spine and the jade pillow four passes, with the power of Wan Jun rushed to the Tianling cover Baihui acupoint, did not follow the previous old way to the upper dantian point located in the center of the eyebrows, but a dragon out of the hundred will be divided into two dragons, respectively along the ears and cheeks on both sides of the waterfall straight down the cliff posture down the magpie bridge, the two dragons waded through the magpie bridge before and then converged into a dragon, with the unstoppable momentum of the magpie bridge after rushing through the magpie bridge at the head of a life door, rushed into a new meridian avenue.

"What?!" Tu Gu was stunned on the spot, he found that the brand new meridian completely coincided with the route of the Ren vein that had been depicted thousands of times before, and it should be that the Ren vein was correct, "Could it be that this juncture has broken through?"

"Whoosh!"

The bullet hit the pangolin's visor and was bounced off again.

"Boom!"

There was a faint thunder sound in the body of the spitting bones, and the momentum of the fire dragon vitality rushed into the Ren pulse decreased slightly, and after being disturbed by the bullet, he jumped up again and swam wildly, along the Ren pulse to the Chonglou acupoint, an important point of the Ren pulse, and seemed to get some comfort after rushing into the Chonglou acupoint, so he stayed and lingered.

"Let's go, don't stop!" said the roar of the Zuo Shishi in the communication system.

"Oh, good!" Tu Gu was confused, and he replied in a daze, and walked forward, and when he walked out of a distance of more than ten meters again, the gunfire rang out again out of place.

"Phew!"

"Boom!"

The fire dragon vitality that stayed in the Chonglou Cave and calmed down a little bit rushed out of the Chonglou Cave in anger again, and hit the Zhongdantian Cave located in the heart along the Ren Pulse downward, and after rushing into the Zhongdantian Cave, it once again showed its joy, and once again hesitated.

"Whoosh!" The bullet hit the pangolin's temple and was bounced off again.

The disturbed fire dragon's vitality rushed out of the middle dantian cave with rage, and the pulse returned to the sea cave along the pulse, like a tired bird returning to the forest and a dragon entering the sea.

At this time, looking at the route of the fire dragon's vitality cruising, a thin line has already penetrated the qi sea cave, the Du vein, and the Ren vein, and the vitality is flowing in it, endlessly.

Previously, the fire dragon vitality used the qi sea cave as a lair, and was jealous of the burning red ball, so it behaved very honest and docile in the qi sea cave, but this time it was different, the fire dragon vitality was still restless after returning to the qi sea cave, cruising around, climbing, and drilling camps, but it seemed to have no way, and after a long time, it became more and more irritable, after many attempts to no avail, it seemed to have nowhere to go, it turned around and slammed into the red ball in the center of the dark secret room, as if it had the posture of ending up together.

The "——!" fire dragon vitality and the red ball instantly burst out with hundreds of millions of dazzling golden lights, illuminating the entire dark secret room, and at the same time, the dark secret room shook very violently, causing the resonance of heaven and earth.

"Boom ——!"

The dark secret room in the belly and navel collapses!

Master Zuo, who was observing the spitting bones from the telescope, saw that his figure seemed to have wisps of golden light shooting out, but when he removed the telescope, he saw nothing.

"Is it an illusion?" said Master Zuo.

Tu Gu Hu, on "Huangquan Road".

Little Sunday, become!
