Of course, the crystal nucleus was not all used by the eldest sister, she actually didn't mean to ask Jiang Yuan's crystal nucleus, but to confirm her guess, and after seeing it, she turned her head and drank her classics.

Jiang Yuan didn't use these crystal nuclei immediately, but put them away, and the most important thing now was to study the sword qi he had just seen.

In fact, it is not only Mo Bei's knife qi that causes air vibration, but also the eldest sister's fist style can also cause that kind of explosion, however, the eldest sister's attack cannot break the tentacles of the tentacle monster, which shows that to a certain extent, Mo Bei's knife qi is more severe!

Moreover, the eldest sister's fist wind energy dissipated quickly in the air, and Mo Bei's sword qi, that kind of energy was so gathered, a line was cut out, and the surroundings were not affected at all, and when there were still about twenty meters away from the tentacles, they could even cut off such a tough tentacle. And judging from this effect, the distance and range that a sword qi can attack is very large, and it is far less than the physical strength consumed by the eldest sister to swing that punch.

With the foundation of inch strength, as well as the comprehension from the eldest sister's fist style, coupled with the absolute perception of space, it took Jiang Yuan about an hour to finally successfully master the molecular tremor, which can release an attack similar to knife qi!

In fact, it is possible to release "molecular tremor" without the help of weapons, but with the help of weapons with blades such as swords, the concentration and harmony of molecular tremor are much easier, and the effect of concentration is more obvious, which also causes a gap in attack power and attack range.

However, because of the vibration of high-frequency molecules, the destructive power of the sword is also great, so according to Jiang Yuan's research, the best way is to find a suitable alloy knife, or a knife with a very high molecular density, so as to prevent a fracture similar to Mobei's alloy knife during the battle.

In layman's terms, the heavier the knife with the same volume, the better the effect!

At present, the best knife is the alloy knife that Xiao Yuheng equipped with a few people to be able to use it alive, and it is difficult to say how many other estimates can be wielded.

Mo Bei's knife has been broken, but there are a lot of things in the materials in the Jiangyuan space, including more than a dozen alloy knives of the same type, these knives are made in the style of imitation Tang knives, and the materials are all high-strength alloys synthesized by Xiao Yuheng's ability.

After mastering the "knife qi", Jiang Yuan turned around and hugged the eldest sister who was "already asleep", but what he didn't know was that when he hugged him, the corners of the eldest sister's mouth were slightly raised.

The biological clock of the special person is well controlled, because the perception and grasp of the body are stronger, so it is also a very simple matter to regulate the biological clock, and no one in this world dares to sleep soundly, right?

Uh, except for this one in Jiang Yuan's arms!

The county town of Hirano has a lot of supplies, the houses here can still keep warm and protect against the snow, and there are basically no threatening creatures around, so they know that they can leave when they notice the arrival of the large army in the early morning.

Long Zaiye and a special person who led the rest of the personnel handed over the situation here, which roughly means that there may be potential dangers.

This place is not very far from Gangtie City, so there is no need to consume the materials that Jiang Yuan carried, and the materials in his space are used when he is remote.

Seeing that the large army began to camp here and build communication equipment, Jiang Yuan and the others left and continued to the north to explore new places.

Just how far I went out, I encountered so many dangers, which made several people a little worried, but the harvest was also great, well, the biggest gain was of course Jiang Yuan, but the others at least had more experience in fighting different monsters, didn't they!?

……

Gangtiecheng, Provisional Academy of Sciences.

"Professor Gu, how is the blood wheat improving now?" Xiao Yuheng walked into the research room and asked with a solemn and expectant face.

"Still not, although it can be grown without flesh and blood, but the growth cycle is as long as three months, and the nutrients contained in it are also very different, only three times that of ordinary wheat." Gu Changqing sighed.

The nutrition is three times that of ordinary wheat, and the growth cycle is only three months, if it is before the end of the world, the people of the Academy of Agricultural Sciences will definitely be ecstatic. However, this is the end of the world, and the current environment is only this one crop that can be planted on a large scale, and now it needs to quickly produce enough food for everyone in the entire Iron City!

Before the improvement, the blood wheat not only had ten times the nutrition and yield of ordinary wheat, but also had five to six times the yield of ordinary wheat, and it was rich in energy that could be used by special people, and the growth cycle only took three days when there was enough flesh and blood!

Three days and three months, one and ten, one and five or six, these numbers kept flashing in front of Xiao Yuheng's eyes.

Moreover, the grain stored in the Iron City now, all the food that can be counted, is only enough to supply for two weeks, and after two weeks, there will be an ice famine! Human beings, under the control of cold and hunger, do all kinds of terrible things, what it means, he, the city lord, knows better than anyone else!

Seeing that Xiao Yuheng didn't speak, Gu Changqing continued: "Our improvement is still fruitful, under the same conditions, the yield of wheat produced by Blood Wheat GT01 is six to seven times that of ordinary wheat, and the nutrition is twelve times that of ordinary wheat, although the growth cycle has changed from three days to one week, but the amount of flesh and blood required will also be reduced to one-tenth." In contrast, there has been a lot of progress. ”

Xiao Yuheng nodded when he heard this, but he didn't speak, and continued to ponder, although it was reduced to one-tenth of the original, it still needed flesh and blood.

Now, most of the zombies have migrated south, mutant beasts and insects are too, and a small number of them exist in a certain mountain forest, which is not easy to obtain, so there is only one of the cheapest and most cost-effective flesh and blood - human beings themselves!

He knew very well what the impact would be if the blood wheat that required flesh cultivation spread over a large area, but there were still two weeks left, and he didn't have time to think about it!

Xiao Yuheng raised his head and asked again: "Can't there be any more big aspects in a short period of time, such as a breakthrough in the need for flesh and blood?" ”

Gu Changqing shook his head and did not speak.

Xiao Yuheng didn't continue to ask, turned around, and at the same time ordered: "Immediately, prepare the seeds needed for large-scale planting, and I'll take care of the flesh and blood!" ”

After this night, in the Iron City, whether it was the military or the Lord's Mansion of the Iron City, all the prisoners in the prison disappeared, whether it was theft or robbery, murder or force, overnight, the world evaporated!
