Ishiharano and Chen Qinqin followed Zhang Xiaoqiang in the direction of Taniguchi, where the two mountains were now fortified by Zhang Xiaoqiang, and a large number of building materials were brought in from the outside at any cost, building improvised fortifications into permanent fortifications, and transporting generators and diesel fuel at the same time.

All of these things can only be transported by mountain roads, which are difficult to travel, and it is impossible to use motor vehicles at all, except for people carrying them on their shoulders, the only things that can be used are bicycles and wheelbarrows.

Looking at the fortifications that were being built, Ishihara Ye felt a little distressed, a lot of manpower and material resources were wasted here, you know, the original defense system here was good, he thought that even if the Botanical Research Institute was here, there was no need to make it like this.

When they arrived at the big lake, Zhang Xiaoqiang took the two of them to a lifting platform at the foot of the mountain, and the three of them started with the lifting platform, and reached the ten-meter-high halfway up the mountainside, walked up the rocky road on the mountainside, and came to a natural cave, the cave is very large, there are at least thousands of square meters inside, the four walls and the ground have traces of being organized, and the simple wooden tables occupy half of the space of the cave, and the remaining half is a variety of experimental tables and research equipment.

Walking past the simple wooden tables, Ishiharano saw that there were three clay pots on each wooden table, and in the clay pots grew a strange plant, all of which were single, like a pearl necklace that had been torn off and then glued into the soil.

At the very top of the plant, there is a very strange fruit, to be precise, it looks like a woodpecker's beak embedded in the largest pearl, the long black and blue thorns extend seven or eight centimeters, the thorn head is facing the outside of the clay pot, and on the tip of the thorn, there is a transparent silk thread that hangs down into the small bowl on the side of the clay pot.

There was already a small half bowl of transparent gelatinous substance in the small bowl, and suddenly, Shi Yuanye couldn't tell whether it was the gelatinous matter in the bowl that was sucked dry by the spikes like a bird's beak, and it should be the spikes that spit into the bowl again.

Then he found that these plants were also arranged in other ways, and the women with masks walked quietly between these wooden tables, spraying water mist onto these plants with the sprayer in their hands from time to time, and the crystal water droplets slowly flowed down the small pearls in the middle of the plants, and were completely absorbed before flowing to the last pearl.

"Or the zombie rot water?"

Shi Yuanye smelled a faint smell in the air, and asked Zhang Xiaoqiang suspiciously, but he had some interest in these plants in his heart, Zhang Xiaoqiang is a person who pays attention to interests, let him give up cleaning up two hundred zombies and obtain the benefits of the entire Yinchuan Plain to farm here, it will be, the benefits here are much more than outside?

"Yes, in the later stage of the garrison's encirclement and suppression of the zombies in Helan Mountain, I ordered them to drive all the zombies to several Jedi, and then seal the gap, now there are 100,000 zombies trapped by us in the entire Helan Mountain, and I have put ten evolutionaries and twenty veterans in each Jedi, and there will be no accidents.

These zombies are the fertilizer of the Botanical Research Institute, and now we have a share of the credit for any breakthrough we have made, so don't worry about these things, I'll show you our results....... ”

Zhang Xiaoqiang took Shi Yuanye to the side of the experimental table, but saw a few men and women in white coats testing something over there, all of these people were not seen by Shi Yuanye, everyone had various old wounds on their faces, and their faces also had traces of long-term hunger.

Zhang Xiaoqiang didn't care about these people, walked to a shelf by himself, took something and handed it to Shi Yuanye, and when Shi Yuanye took it, his right hand fluttered violently, as if he couldn't control his strength, it was too light.

Zhang Xiaoqiang handed him a helmet covered with camouflage cloth, which looked no different from the field helmet they used, but when he held it in his hand, he couldn't feel the weight of the helmet at all, and similarly, he couldn't feel the thickness of the helmet, and the impact was that this thing was like being made of plastic sheets to bluff people.

Shi Yuanye took the helmet in his hand and looked through it carefully, and he couldn't see a name, staring at Zhang Xiaoqiang with some curiosity, Zhang Xiaoqiang smiled and didn't answer, grabbed the helmet and took Shi Yuanye to a cave next to the experimental area, the space of this cave is long and narrow, but the cave wall on one side has been chiseled out of dense small eyes, the sunlight outside shines into the cave along the small eyes like a sieve, and countless gold-like pillars of light illuminate the cave brilliantly, but more dust flies in the pillar of light.

This cave has signs of being used as a shooting range, on the rock wall, small eyes have chiseled the rocks, and countless gravel has fallen on the ground, on the wall near the exit of the cave, on a row of gun racks, various standard rifles are neatly arranged, and in the large barrels under the gun racks, dense bullet casings fill half of the barrels, and several ammunition boxes are built on the side of the barrels, and several half-full magazines are piled on top of them.

The long and narrow cave is 100 meters long, and there are several crosses in the middle according to the distance, Zhang Xiaoqiang walked to the first shelf, tied his helmet to it, returned to Shi Yuanye's side and asked:

"With the Bayi rifle, at this distance, shoot the helmet we are equipped with, can the helmet block all the bullets?"

Ishiharano looked at the helmet twenty meters away speechlessly, and shook his head directly, although the new generation of steel helmet is good, it is not omnipotent, the kinetic energy of the 7.62 mm bullet is too great, let alone twenty meters, even if it is fifty meters away, it can't be stopped.

Zhang Xiaoqiang grabbed an Bayi rifle, stuck the magazine, pulled the bolt, and when the machine buckle sounded, the rifle was handed to Shi Yuanye, looking at the rifle in front of him, Shi Yuanye hesitated to take it, and pulled the trigger on Zhang Xiaoqiang's fixed helmet when he raised the gun.

After firing with a single shot, Ishiharano squinted his eyes to look at his results, and as expected, the skin of the helmet was torn open, and at the same time, the helmet material under the mouth was also blown away, and through the sunlight shining in, the wooden frame under the helmet could be seen.

Ishiharano raised the muzzle of the gun upwards, looking at Zhang Xiaoqiang suspiciously, he didn't know what Zhang Xiaoqiang was doing, the helmet was garbage, there was no doubt about this, the only thing that could be said was this cave, the countless small eyes on the wall could dissipate the gunshot, and it would not reverberate in this cave.

"Don't you understand?"

Zhang Xiaoqiang said that he was very surprised, he grabbed a five-six submachine gun, neatly put on the magazine, raised the gun and shot out the bullets of the slowly magazine, the steel helmet trembled violently in the rain of bullets, countless sparks flashed on the helmet, and at the same time, the bullets that bounced off were also whistling, hitting the surrounding rock walls, and chiseling out countless small stone chips.

"This ...... What is this thing......"

Ishiharano didn't wait for the smoke in front of the two of them to dissipate, took the initiative to rush to the cross, and carefully looked at the helmet fixed on it, the skin has been torn into strands of cloth, and the material inside made Ishiharano see a clear, under the fully transparent skin, is the lining fixed in the helmet, from the outside, the material in the middle of the helmet seems to be non-existent, only the skin and the lining are composed, it is very weird.

Seeing Ishiharano playing with the transparent helmet in his hand, Zhang Xiaoqiang felt comfortable for a while, feeling that it was worth being a monkey in the mountains every day some time ago.

"Glass bulletproof armor, this is the name I am going to tell the user, and the glass armor is used internally, the real material, I call it pearl tears, which is the plants you just saw, and this armor grows on trees."

Hearing Zhang Xiaoqiang's words, Shi Yuanye frowned and said:

"What's the production of those pearl tears out there? Also, equipping tens of thousands of troops, this thing seems to be a bit redundant, and the helmets we are currently using are enough, I think ......"

Zhang Xiaoqiang smiled dumbly, raised his hand to stop Shi Yuanye's words, he stared at Shi Yuanye seriously and said:

"You're mistaken, I never thought of making this thing into a helmet from beginning to end, and its range of use is not so simple, let me put it this way, you can use it as a dream material of the future of super technology, its melting point to high temperature is 4,200 degrees, it will not be brittle at all under 30 degrees of freezing, and it can resist the scattered burst of 1.27mm bullets......"

Every time Zhang Xiaoqiang said a word, Shi Yuanye's expression changed a point, and in the end it had changed from surprise to horror, when he heard that this thing was simple to process and had the ability to form once, he suddenly changed color and said:

"Brother cockroach, we can't use this thing now, there are still some forces in the outside world, we don't know, this thing is not only useless to us, but also may attract the prying eyes of all forces, it is best to study it slowly, form a system, and let our technology reach a certain level, and then take it out......"
