"Master, kill the overlord-level alien beast to get 5T tough cortex, 0.3T abnormal bone, and the core of the alien beast is still in place." Chariot Ji reported the results of the battle.

Zhang Zhen let the fortress advance to the valley, and once he found the loot and bones, he was surprised: "I know that the skin of the alien beast can be used as a material to strengthen the defense of the chariot, what are the bones?" ”

Chariot Ji replied: "The physique of the alien beast is mutated, and the bones may also reach the level of metal elements like the cortex, and the two tailbones of this alien beast and the six bones in the body contain alloy-grade elemental attributes, which can replace some metals, and also have some characteristics that are lacking in alloys, such as making parts that will not be affected by extreme temperatures. ”

Zhang Zhen raised his eyebrows, this sounds magical but also very cool, the beast bone can also be used for metal parts.

Xiao Yunfei flew into the valley with a battleship, landing on the corpse of the ruin-like alien beast, and some light came out from below.

Only then did the soldier sitting in the back react from the shock, grabbed the battleship and looked at the stone-like fragments on the ground and exclaimed: "Is the stone a fine?!" ”

Xiao Yunfei dipped his hand on the broken place on his forehead, looked at the blood on his hand and didn't care, he jumped off the battleship directly and gouged in the corpse of the alien beast, the huge body of the alien beast was broken into thousands of small pieces, it felt like a fossil in his hand, the weight was lighter than that of ordinary stones, and the fault inside was like dry and hard bread, and he couldn't understand the physiological state of this alien beast.

If he didn't understand it, he ignored it, he quickly threw the remains of the alien beast in the bright place, and gradually created a big pit, the red light below became more and more obvious, it felt like a big crystal nucleus, and he quickly planed it excitedly.

The fortress slowly heard the mouth of the valley, and the people inside ran to the deck outside the fortress and looked at a ruined mountain range in the valley that seemed to have been blasted at a fixed point, and it was hard to imagine at first glance that it was originally a strange beast, and no one had ever seen such a strange beast as a physique.

"Found it!" Xiao Yunfei excitedly picked up the crimson crystal nucleus, which was only a little smaller than a basketball, and he raised his hands to show it excitedly towards the fortress.

"Well, it looks like the Corpse King's." Zhang Zhen was overjoyed when he saw it, then there are now two crystal nuclei that can make crystal nucleus reactors, and as soon as he finds the crystal nucleus reactor, he can replace the energy system in the current fortress, and he still doesn't feel very at ease about the nuclear reactor.

Xiao Yunfei returned to the fortress with the crystal nucleus in the cheers of everyone, and all the soldiers surrounded him, this battle of ion cannon let everyone see what destruction is, and Xiao Yunfei's bravery also made them even more revered and admired.

Zhang Zhen walked down the stairs, and the crystal nuclei like the stars and the moon were held high in the crowd, and said with a smile: "The first battle of the fortress was won, everyone has made great contributions, and Captain Xiao is the first merit, we have to hold a celebration banquet." ”

"Long live the castle lord!" The warriors cheered.

Xiao Yunfei hurriedly held the crystal nucleus over and said, "This is the responsibility of subordinates. ”

Zhang Zhen took the crystal nucleus and played: "You and the Flying Dragon Brigade are doing very well, go and treat the injury first." ”

"Yes!" Xiao Yunfei retreated excitedly and cautiously, he knew that this time was different from the past, compared with before, it is not an exaggeration to describe the earth-shaking changes, his team is no longer the same as before to drive a chariot and listen to orders, and the things he will face in the future will be more complicated and difficult, he must let Feilong Da He has the ability to bear the courage and complete it to live up to the expectations of the city lord, otherwise someone will replace them in the end.

There is still not much known about the crystal nucleus Zhang Zhen, the energy conversion of the ball is only to replace the battery, but this process Hu Hai can not replicate now, you can imagine what kind of cutting-edge talent can make a crystal nucleus furnace that can replace the nuclear reactor, the crystal nucleus of the alien beast is so stable but contains huge energy, if the crystal nucleus furnace technology can be fully used, then the energy of the last days will not only not be lacking, but will be more developed.

He had an idea, if he mastered the technology of making a crystal nucleus furnace, it would not be possible to build a production line in the last days, the lack of resources could be brought from reality, and after building a large number of crystal core furnaces, he would solve any problems except for food, and then build a rainbow city, and then he would definitely be able to overcome the problem of planting in the last days.

If he really can, then he really became a savior, giving a new hope to the end times, and it is not necessary for mankind to be reborn after the catastrophe.

"Master, I've brought all the food." Sakura went to the dragon and took out meat, tobacco and alcohol, and the drone grabbed it and sent it over.

Zhang Zhen withdrew some boundless thoughts and nodded, "Take it to the kitchen and hand it over to Li Langlang to be responsible." ”

Sakura nodded and walked towards the restaurant in District 6 with the drone.

Zhang Zhen summoned another drone, and let the drone grab the crystal nucleus and send it back to the dragon.

He returned to the command room and looked at the path out of the canyon, it can be said that there is no other way along the way, just follow the canyon down, the fortress can only walk ten kilometers in an hour in this very bad environment, it seems that it will take several hours to get out of the canyon.

After the evolution of the chariot, a lot of expansions have been obtained, one has been added to the folding space Jiaolong, and one has also been obtained in the fortress, and the space of the fortress is three large Jiaolong, because the fortress itself has a large space, so the combat readiness is only normal loading and is not a subsidiary position, so now the fortress itself has an additional vacancy for the attached chariot.

"Master, I don't use polar cortex, if it is still lacking in the fortress, my suggestion is to use it as needed, it can be applied to combat vehicles, drones and power bones, enhance the stealth camouflage ability of these combat preparations, and also improve the defense against elemental damage." Chariotehime is conducting follow-up research on the evolution of the fortress.

Zhang Zhen nodded and said, "Then don't upgrade it first, and use it when you need it, what do you think of tough cortex and animal bones?" ”

"The amount of tough leather is enough to increase the defense of a fortress, but I recommend finding some more metal to craft for the same purpose, so that you can save some tough leather and strengthen other combat readiness. As for the bones, they can be used to repair damaged combat readiness, but they are the most suitable for crafting bladed weapons. Chariot Ji replied.

Zhang Zhen's eyes lit up when he heard this, and said: "Don't be in a hurry to strengthen the fortress first, I will transfer back the black gold when I return to Longyuan City, and you will strengthen it when the time comes, and the beast bone will help me make a blade equipped with black wings first." ”

"Yes, I recommend the Ion Double Spinning Blade, the material in the fortress can make an ion energy device, and when it is opened on the bone blade, it will form an ion knife on the curved blade, which can strengthen the attack power of the weapon for a short time, and if the double blade is combined into a full moon, it can form an ion shield, which can resist attacks." Charioteer Ji did a lot of research on Black Wing and directly recommended a suitable blueprint for combat readiness.

Zhang Zhen looked at the simulated state of an ion double spinning blade in the thinking space and became excited, the half-moon scimitar was attached to a blue ion energy, and the two knives instantly formed a round shield full of energy, and the attack power was A+ when the ion energy was not attached, which was related to the strength of the body, and there was an attack power of S+ directly after attaching, which was the best in light weapons.

"Yes, just help me build the Ionic Twin Blades." Although Zhang Zhen has a fortress, he still can't help but want to enhance his combat effectiveness, "By the way, Black Wing, you just need to look at it and strengthen it." ”

He now fully trusts Chariot Ji's ability, after all, people are experts, and he, the owner, can sit back and enjoy his achievements.
