No one spoke, and everyone was silent as they descended from the Star to the top of the mountain, all frightened by the power of the sixty rockets. Pen Fun Pavilion wWw. ｂiquge。 After the explosion, they felt a violent shock wave on the ship ten miles away.

The smell of gunsmoke still lingered on the hillside, and the group stood on the top of the mountain and looked down to the foot of the mountain, and the area that stretched out for four kilometers to the left and right was razed to the ground. A large crater with a radius of more than 300 meters appeared at the center of the explosion.

The old man only felt that his mouth was dry, don't look at him as a Great Perfection cultivator, but if he was too close to the center of the explosion, I am afraid that he would not be spared.

"If there had been such a weapon earlier, then the Ten Thousand Throats and Ten Thousand Hands Monster would not be able to withstand two volleys!" The old man secretly said in his heart, now that he is completely convinced, the power of the rocket salvo is not a little more powerful than the super bomb.

Tang Chuxue also had a solemn face, with her current strength, she didn't dare to say that she could withstand such an explosion.

Wang Heng and the other private soldiers were even more dumbfounded, and they felt a little trembling when they thought that these powerful rocket launchers were launched by themselves.

Only Jiang Xingchen kept frowning from beginning to end, and the expression on his face was not very good-looking. Although the power of rocket artillery has been proven, the actual effect is not satisfactory to him, and there are still many problems to be solved.

The first is the weight, because it is a yuan stone, explosives and a small yuan qi burst array triple blast, the weight of a single rocket is seriously exceeded, and the weight of three tons also makes the fuel propulsion loss huge, and the range is really unsatisfactory to him.

In addition, there are huge bomb bodies that will cause a burden of transportation, and they simply can't carry many such rockets. At the same time, because the rocket is very thick, the launch tube is also much larger, and the burden on the ship is even greater.

There is also the difficulty of reloading, after one salvo, the process of reloading is quite cumbersome, and it will take too long to carry out the second strike.

Finally, the cost is high, the rocket engine is disposable, and the consumption of colorful crystals alone will cost more than 20 pieces. Coupled with the crystals that are also needed for the small Yuan Qi Burst Array, as well as the Yuan Stones used inside, the cost of a rocket is at least one million citrine coins. In other words, this salvo just now, 60 million citrine coins were thrown in, which is equivalent to the money earned by Xingchen for a month's travel.

After careful calculation in this way, there are still many areas for improvement in rocket artillery. How to make the rocket launcher lighter, have a longer range, and still maintain its power will be the focus of future research.

As for the cost issue, this cannot be avoided, unless the formation is completely discarded and the rocket engine is redeveloped. But this is tantamount to starting all over again, Jiang Xingchen really can't afford that time.

There is also the question of how to rationally distribute the firepower on the ship. Rockets are not suitable for naval warfare, they cannot carry out precision strikes, only against fixed targets on the ground are more suitable. Using such a costly weapon to fight a naval battle, Jiang Xingchen himself had to vomit blood.

"Boy, why are you frowning all the time?" The old man finally came back to his senses, touched Jiang Xingchen lightly, and asked a little strangely.

"Not too happy with the rocket artillery!" Jiang Xingchen shook his head and replied, in fact, this kind of rocket artillery is far from the rocket artillery on the earth in his memory.

"What?" The old man's mouth grew up, and he secretly said in his heart: "This kind of power is not satisfied, are you human? What kind of weapon do you want?"

Tang Chuxue, Xian Ning, and Wang Heng and the private soldiers all looked at him in surprise, and were a little stunned by his words.

Jiang Xingchen glanced at everyone and listed the shortcomings of the rockets in this experiment one by one. Everyone's expressions changed again, did rocket artillery have so many shortcomings? But if you think about it carefully, this is really the case. Especially when Jiang Xingchen mentioned that he threw away 60 million citrine coins in an experiment, a sound of inhalation sounded on the top of the mountain, and even people like the old man and Tang Chuxue, who never cared about money, felt distressed......

After returning from the northern seas, the researchers and craftsmen once again devoted themselves to the refinement and research of rocket artillery.

And Jiang Xingchen, Tang Chuxue, Xian Ning and others returned to the Star Domain. After being away from home for too long, Jiang Xingchen missed Mei'er and his two children, and was ready to go back to the territory to live for a while. His other idea was to send Xian Ning back and prevent him from participating in such a dangerous job as weapon development.

Tang Chuxue also went back with her, and she also missed her son.

The only one left behind was the old man, because a new weapon was being researched here, and someone was needed to guard it, so he was naturally the best candidate. Of course, the old man was very dissatisfied with such a decision, and tried his best to ask to go along, and let Jiang Xingchen promise the benefits of a hundred bottles of vitality wine. In the end, it was Tang Chuxue who came out and forcibly suppressed the old man, which allowed the old guy to stay in Minggang City.

When he returned home, the first thing Jiang Xingchen did was to tell Mei'er about his relationship with Xian Ning. Mei'er also showed the bearing of being an eldest sister, and pulled Xian Ning to whisper for a long time. Jiang Xingchen was embarrassed to stay in front of him and ran to see his daughter.

And Xian Ning is also embarrassed here, Mei'er's original intention was to hold a wedding for her and Jiang Xingchen, but Xian Ning disagreed, and begged Mei'er and Tang Chuxue not to spread the word, otherwise she really wouldn't have the face to see the little cat girl, Mo Hongxian and these sisters.

Mei'er looked at Xian Ning with a resolute attitude, and in the end, after conciling with Tang Chuxue, she could only agree to Xian Ning and not announce this matter to the public for the time being.

After speaking, Xian Ning didn't stay in the lord's mansion for a night, and hurried back to the university. It made Mei'er and Tang Chuxue a little confused, even if you don't announce it, you are also a family member, isn't it good to live in the Lord's Mansion?

However, they couldn't force Xian Ning, so they had to tell Jiang Xingchen.

Jiang Xingchen didn't care about this, Xian Ning asked not to hold a wedding, obviously he didn't want others to know, how could he live at home?

Although Xian Ning tried her best to hide it, when the two had that kind of relationship, they would still show it inadvertently, especially when they were together, it was difficult to hide it from a clear-eyed person. And if you want to say that the smartest in the star realm is Ling'er. So it didn't take long for Ling'er to discover their anomaly.

This discovery made Ling'er very depressed and very encouraging. The depressed thing is that the third one is not himself, and the encouraging thing is that the third one is gone, and it is not difficult to have a fourth one. So during this period, she often went to the Lord's Mansion to find Tang Chuxue to inquire about Minggang City.

Xian Ning and Jiang Xingchen had no idea about this, and soon after they returned, they devoted themselves to intense research work. Jiang Xingchen is still studying formations, and Xianning is committed to the exploration of radio. It's just that the two always get together, and at night they often misfire, and no one can control it......

And so it went for another two months, and word came from the Cursed Lands that two more steel ships had been successfully launched. At the same time, the people they sent in various places finally sent back the news and made a discovery! (To be continued.) )
