The rain was pouring down, but it was difficult to cover the flames that soared into the sky. Under the firelight, the dark sky was suddenly illuminated with a fiery red. Billowing smoke rose from the sea of fire, forming a behemoth in the air, looking down on the earth with a hideous look.

The moment the fireball was thrown, Han Feng didn't think that he could ignite these plants. Han Feng didn't even know if he could touch those plants in the direction in which the fireball was thrown. He didn't expect that such a fireball that was destined to be extinguished in his heart ignited a fire. The black stagnant water on the ground is like a pool of gasoline, and it will burn quickly when it encounters a little spark. The sea of fire was spreading rapidly along the black stagnant water, and in an instant, it filled the entire area covered with plants.

Looking at the fire below that had not been extinguished in the heavy rain at all, not only Han Feng was very surprised, but even the others were also very surprised. None of them expected that the black stagnant water on the ground would be so flammable.

The entire willow-like plant was all surrounded by the fire, and Han Feng no longer hesitated to do anything, taking advantage of the fire burning, he began to control the surrounding air, strengthening the oxygen in the fire sea area, and helping the fire burn more vigorously. At the same time, Han Feng also continued to slash out wind blades into the sea of fire, cutting off the plants inside. The liquid that erupts from the plant burns as soon as it encounters a flame. It is more flammable than standing water on the ground. Standing outside the fire, you can see fire snakes rushing up from the fire. The fiery serpent was formed by the liquid that the plant spewed out after it was cut off.

Plants that were thought to take a lot of effort were easily eliminated by a fire. Han Feng told some soldiers to stay outside the fire and watch, and notify him as soon as they found something abnormal. I went back to the base to rest.

Time passed slowly, the rain was still falling, and the clouds in the sky did not change in the slightest, making it impossible to see how long this rain would last. Heavy rains caused many rivers to rise. Especially the large rivers rise even faster. Han Feng's headquarters base is next to the Yangtze River, and looking at the rising water level of the Yangtze River every day, Han Feng is really worried that if this continues, the entire base will be flooded.

The food problem at the base is still not well solved. Many residents have begun to leave the base and live further afield. Because they know that the base will not be able to solve their rations. And the monsters around the base have been almost killed, and only by going farther away can you find food more smoothly. If they bring the food they find back to the base, they will be robbed. It's better not to go back, anyway, among the people who leave the base, there are people who have completed the key evolution, and they can be regarded as having a certain ability to protect themselves.

On the headquarters building, there are quite a few people fixing several strange machines around the building. These machines were like a small tower, the same as the protective shield equipment that Han Feng had brought back from the bottom of the sea. It's just a lot smaller. After more than ten days of hard work, Liu Xing's team finally succeeded in replicating the protective cover equipment. Today is the day for them to conduct their experiments.

In a 10-story building not far from the headquarters building, a large net is being erected around the building. They're going to use this big net to wrap the whole building. This large net is also considered a form of protective cover. It was achieved by scientists based on the concept of the previous human beings themselves, with the theory of the protective shield device.

After the device connected to the large network is activated, it will form a protective layer on the large network, which plays the same role as the protective cover.

The protective shield equipment that Han Feng brought back was to form a pure force field energy, and after this energy field was processed by the machine, a special energy layer would be formed. Any external force that touches these two layers of energy will cause the energy field to produce a blocking force. It is precisely this force that the shield relies on to protect the target. Such a protective shield only needs a few devices to form a force field and the ability to process the force field, and does not need any object to be the carrier of the energy layer. It can be used quickly anywhere. It is a very convenient protective cover. And the protective cover with a large net as a carrier will be a little more cumbersome. The area to be protected must be netted in advance to achieve the effect of protection. And the strength of this shield and the net is related.

Don't look at the hassle of covering an area with a large net. But the equipment required for this method is much easier to make than the equipment that Han Feng brought back. The energy required is also much smaller. It is very suitable for some small bases.

The people in the base who knew about the imitation shield were going to be tested today. Looking at the equipment being installed, everyone's heart is both apprehensive and excited. Especially those scientists who are in charge of research. They are definitely the most nervous of them all.

When everything was ready, Liu Xing personally pressed the switch. The machines arranged around the headquarters building were slowly running. A layer of light blue light mask, with the operation of the machine, little by little appeared around the headquarters building.

Experiments have also begun on another building wrapped in nets. Compared to the headquarters building, it is much quieter here. The large net that encloses the building does not show any anomalies. Only the sound of critical equipment can be heard.

It didn't take long, and in everyone's expectant eyes, the headquarters building was completely wrapped in a blue light mask. The people who watched it all cheered. Although they hadn't tried the effect of the blue mask yet, everyone couldn't help but cheer when they saw a spherical light mask enveloping the building. Even if the mask shatters in the next moment, in this second, it is worth exciting.

Looking at the stabilized light mask, Han Feng got a hint from Liu Xing. He pulled out a captured Powerstone pistol and aimed it at the pale blue light mask that wrapped around the building. The excited chattering of the surrounding people also quieted down at this moment. Everyone's eyes were fixed on the place where Han Feng's muzzle was aiming.

Pull the trigger, and a flash of bullet heads towards the shield. Everyone's hearts were lifted at this moment. Han Feng also looked at his front with a nervous expression. When the light bullet hit the shield and spread out like a firework, everyone's hearts relaxed. The cheers rang out again.

The moment the shield was attacked, it only flickered slightly, and it was very stable. After Han Feng saw that the first shot was successful, he shot more than a dozen glowing bullets in a row, but all of them were blocked by the protective shield. The scientists, who had been testing the various data of the protective shield, told Han Feng the data they had detected in time. Although Han Feng couldn't understand these data, after Liu Xing's explanation, Han Feng understood that the current protective shield was very stable.

After trying it with a pistol, Han Feng took out a big gun. This large gun, seized from a mysterious organization, is more powerful than a bazooka. If the protective shield could block the attack of the big gun, then Han Feng would be more at ease.

Directly adjust the power of the gun to the maximum. This time, Han Feng didn't hesitate and directly pulled the trigger to launch a glowing bullet. The recoil on the gun was very large, but it had no effect on Han Feng. After the shield was attacked, the blue light spread out like water waves. The glowing bullet also failed to break through the shield's defenses.

When Han Feng was testing the protective shield, another test site also started testing. The protective shield with a large net as the carrier looks very ordinary, but the moment it is attacked, a reddish layer of light will appear on the attacked part, blocking the attacking object and destroying it. Whether it's an energy attack or an object attack, as long as you can't break through the barrier of the protective shield, you will only be destroyed.

If a person collides with the protective shield that Han Feng experimented with, the protective shield would bounce the person away. The energy of the shield itself is limited in how much damage it can do to a person. And this kind of protective shield with a large net as the carrier, if a person hits it, what happens is an explosion.

Experiments with both shield devices were very successful. While doing more tests, Han Feng had already ordered the start of mass production of protective cover equipment. He had to protect the base with a protective shield as soon as possible.

The experiment had just been successful, and before Han Feng and the others could celebrate, his satellite phone rang. Chen Yi of the Northern Central Political Axe called Han Feng. The topic of conversation is precisely about protective shields. You don't have to think about it, Chen Yi already knows that Han Feng has successfully made protective cover equipment here, and he wants to get a piece of the pie. It seems that there are a lot of spies hidden in the base.

"Commander Chen's news is really well-informed. The test on my side continues, and your call is coming. Looks like the commander-in-chief cares about me here? Han Feng said to the phone.

"Comrade Han doesn't have to be angry, I have no choice but to do so. You should also know about the communication channel, and many forces are now talking about getting a ship from your base. I'm so worried about your safety. Now that I heard that the protective shield has been preliminarily tested, I am much more relieved. Do you want to see if you can send me a copy of the production drawings here, so that the capital can be safer here? Chen Yi said on the other end of the phone.

From Chen Yi's words, Han Feng thought that it shouldn't be those scientists who spread the news, otherwise Chen Yi would probably already have drawings there. It must have been done by the inhabitants of the base. Who the spy was Han Feng didn't know, but he didn't expect Chen Yi to be so straightforward. As soon as he came up, he didn't say anything about the protective shield, and admitted that he had arranged for someone at Han Feng's base, and asked for drawings without saying a word, he was really direct enough.

"Commander Chen doesn't need to be in a hurry, now the protective shield still needs to be tested, and when all the data is stable, he will definitely send a drawing, or even a set of equipment to you." Han Feng said. In fact, he kept saying in his heart, if you want to take the drawings away like this, how is it possible, I am not a fool, how can I give it to you for nothing. I want to share something, but I have to charge a little bit of a fee. --------------------- damn shield, wasting my n more time, and n brain cells.
