Xiang Jing asked on a whim, "Yuan, genetic medicine can be fused, is it possible that mutant crystal nuclei can also be fused."

The system didn't reply directly, and it seemed that Xiang Jing's brain was stunned.

It took a while to answer, "In theory, fusion can be carried out, but there is a certain probability that it will fail. For details, please enter the fusion function to view the host."

After Xiang Jing listened, she put the mosaic function on hold, turned on the fusion function, and chose the newly added mutant crystal nucleus fusion.

The original position of only five slots suddenly became ten grooves.

The next column of instructions is displayed, and Xiang Jing read it carefully.

The original mutation nucleus fusion can use low-level mutation nuclei to fuse higher-level mutation nuclei.

For example, the fusion of F-class mutant crystal nuclei into E-class requires ten F-class, and so on, for each level up, ten same-class fusions are required.

If you want to fuse an S grade, you need 1 million F grade mutant crystal nuclei.

And it is not 100% successful. F-level fusion into E-level only has a 70% success rate, and E-level fusion into D-level only 50%.

This is quite high, only 30% of the D-level fusion into the C-level, and only 10% of the C-level fusion into the B-level.

The two things that Xiang Jing can't stand most are the latter two.

There is only a 1% success rate for class B fusion into A class, and a 0.1% success rate for class A fusion into S class.

This means that Xiang Jing has integrated 10 million F-class mutant crystal nuclei, and even if the previous fusions are successful, it will only reach 1% of the successful S-class mutant core.

The difficulty of fusing an S-class mutant spiritual core can be imagined, which is simply an astronomical number.

This fusion success rate is really low and scary. If there are so many mutant crystal nuclei, Xiang Jing has long been directly converted into hunting points. One million hunting points are enough for him to buy a lot of good things in the system store. Will be wasted on this ethereal fusion.

Moreover, EF-level mutant crystal nuclei are directly converted into hunting points, and only those above D-level will be retained by the system.

Xiang Jing found that the fusion of mutant crystal nuclei was a pit, if he jumped into it, don't think of it in this life.

Then he returned to the inlay function, and now let's try the inlay function.

Xiang Jing took out a big knife from a different space and put it into the groove on it.

Only one of the four grooves below is lit up, which means that only one mutant crystal nucleus can be embedded.

Xiang Jing changed the spear again, which could only be inlaid with one, and then changed the large axe and bow, only one more than the knife and spear, which can be inlaid with two.

The only thing that can be inlaid is a giant shield, which can inlay three at the same time.

It can also be seen from the grade that the Great Shield is the highest grade, and it is normal to be able to inlay three pieces.

However, Xiang Jing now has only one mutant crystal core that can be embedded, and the giant shield is used for defense, which is inconsistent with his fighting style that he prefers to attack.

Therefore, Xiang Jing decided to integrate with the big knife. The knife was easy to use, and he opened and closed to chop up the monster.

As for buying some good weapons from the system store, he hadn't thought about it, but the remaining mutant crystal nuclei were still useful, which temporarily dispelled this idea.

Moreover, the inlaid mutant crystal nuclei cannot be removed, and the D-grade ones are not particularly good. They are all small materials used in good equipment, and we will wait for better ones in the future.

After placing the broad knife and the mutant crystal core, Xiang Jing chose to inlay.

An earth-yellow light rushed along the groove of the crystal nucleus to the groove where the sword was located. After the successful connection, a burst of light flashed, and the mutant crystal nucleus disappeared in place.

However, there was an extra yellow light spot the size of a grape on the handle of the original big knife, indicating that the crystal nucleus had been successfully embedded in it.

Xiang Jing went out and opened the data analyzer.

"Name: Broadsword"

"Basic Strength: 15 Times"

"Increase user power: 10 times"

"Inlaid crystal nucleus: D-grade soil attribute crystal nucleus (can enhance the toughness of inlaid items, increase defense 10 times, and power 5 times.

"not bad"

Xiang Jing gave a more pertinent evaluation after reading it.

According to the properties of this mutant crystal nucleus, it is better to inlay it on an armor shield or the like, but it doesn't matter much, so it's an experiment.

In addition, the broad knife has increased toughness and is more durable. For example, this broad knife can withstand a blow of up to 100 times the strength, so the upper limit will be increased after increasing the willfulness, and it will be more resistant to cutting.

In addition, it has increased five times the power, although not much, but with the basic power and enhanced user power, it is quite scary.

After exiting the system function area, Xiang Jing bought a blood translator.

This thing was only the size of a palm and looked like a small stove, Xiang Jing dripped a drop of his own blood on it.

A red light flashed on the essence blood converter, and then resumed as usual. The system helped him to blur and place it on the part of the heart, but Xiang Jing could clearly feel its existence, beating vigorously with his heart.

The essence and blood converter has only one function, which helps Xiang Jingning to develop his own essence and blood. As long as he kills monsters or humans, their blood will automatically be absorbed by the essence and blood converter.

Using Xiang Jing's blood as the standard, he continued to condense, and finally flowed into his heart along the essence blood converter, and merged with Xiang Jing as a whole.

However, it is extremely difficult to condense the essence and blood. Perhaps the death of thousands of monster humans will only make Xiang Jing's vitality stronger, even forming it is difficult.

However, the essence blood converter will continue to wash away the blood in Xiang Jing's heart, so that the accumulation of time can also accelerate the speed of condensing essence and blood.

After doing all this, Xiang Jing returned to the pre-liberation period, with only more than 10,000 hunting points left.

Thinking about buying something more, think about it, forget it, the reward for the timed mission has not been settled, wait until the reward is settled tomorrow, and then see how to use these hunting points, or save it first.

I just don't know what level he will be rated, thinking that I can solve the corpse tide and the beast tide by blowing up and tearing, and it will not be bad to want to reward him.

This is considered to be overfulfilling the task, and I am a little excited to think about rewards.

Xiang Jing is not in a hurry now. Now Yanjing City is safe for the time being, and his strength has also been improved by a breakthrough. He is not afraid of any other monsters, and he will cut his head directly with a single knife. Zhengzhou has no advanced mutant crystal cores. Inlay something for him.

"but"

Calm down and think carefully, Xiang Jing still feels that something is not right.

The first is the crimson beam of light that soars into the sky, which has not dissipated until now and has remained there.

The other one is these monsters, clearly heading towards the beam of light.

But even though the beam of light is on the east side of Yanjing City, this is not the only way and the fastest shortcut for them, so all the people who are so immortal have come here.

"Could it be that there is something in Yanjing City that attracts them?"
