With Jia Zhengjin's current equipment, he has to fight when he encounters high-level magical beasts, let alone insects?

Although the giant insects were dense and numerous, they could not withstand his attack.

The insects that appeared this time included giant centipedes, silver-armored spiders, mutant frogs and other groups, and there were about a thousand of them.

In the face of such a huge insect army, Jia Zhengjin can be said to have exhausted all means in order to be able to keep the farmland and prevent them from destroying the tree of life.

Lay mines, drop bombs, explode arrows, and rain of arrows to keep out all the giant insects coming from all directions. He even did not hesitate to use the staff of corpse poison to resurrect the giant insects that were killed as his own zombies, and formed a powerful zombie army to guard the farmland around.

The accumulated battle lasted for more than an hour, and Jia Zhengjin kept throwing bombs and creating zombies. Finally, the farmland is surrounded by zombies of giant insects and various insect corpses that have been blown to pieces.

When he was so tired that he was about to collapse, he finally succeeded in holding this wave of defensive battles.

【System】Congratulations on fighting off the giant insect army and successfully holding the farmland!

【System】The Tree of Life is thriving, and its growth cycle has been reduced to 47 days!

The Tree of Life needs irrigation to continue growing! If it is not irrigated by the Fountain of Life before it grows up, the sapling will wither and die!

【System】You have completed a random task - Defend the farmland and gain 500,000 experience points!

【System】You've upgraded!

The continuous system prompts made Jia Zhengjin a little panicked, and then he remembered the accumulation of hunting demonic beasts before, especially the group of lobster monster Nadu, killing Nadu larvae who don't know how much, and had accumulated a lot of experience. Coupled with the experience points of the thousands of giant insects just now, as well as the 500,000 experience given by this random task, it was successfully upgraded!

16 levels 17 require more than 3 million experience points, which is enough before you know it!

And what makes him happiest is that the growth cycle of the Tree of Life has also been shortened to 47 days, which is only one and a half months!

The contrast between thousands of years of growth time and a month and a half is incredible! That's the beauty of the system.

In other words, in a month and a half at most, Jia Zhengjin will also be able to have his own Tree of Life, and then get more Spring of Life!

But now it must be irrigated with the Fountain of Life, otherwise the Tree of Life will not only not grow when its growth cycle is reached, but will immediately wither and die.

Jia Zhengjin didn't want to waste so much energy, but he got nothing.

He immediately took out the Fountain of Life from his backpack, used the manuscript to tear down the stone brick walls around the farmland, and then carefully poured a bottle of Fountain of Life into the roots of the Tree of Life.

【System】The Tree of Life is irrigated, and its Life Force is increased by 20%!

Jia Zhengjin was very heartbroken, such a precious spring of life water could only increase the progress by 20 percent after a bottle.

But thinking that in the future, I could let the Tree of Life make more spring water, so I gritted my teeth and took out more spring water.

40%、60%、80%、100%！

Five bottles of Life Spring water irrigated it, and the Life Tree's life force finally reached 100% full value.

【System】The Tree of Life will grow smoothly after the growth cycle!

Jia Zhengjin's heart ached, but he felt a little better when he remembered that as long as he persisted for a month and a half, he would be able to have a tree that produced the spring of life.

However, during this time, he was most afraid of being destroyed by other creatures to destroy the farmland and the Tree of Life, and he must not be negligent! Jia Zhengjin hurriedly used the Staff of Corpse Poison to transform all the insect corpses on the scene into zombies, so that they could hide around to form a huge protective circle, guarding the Tree of Life at all times.

At the same time, I also thought that after I went back, I would let the dryad come and station here, and have it to cooperate with the guards.

In addition to being bulky and unable to enter the water, the dryads are actually very strong. With it, plus thousands of insects and zombies, you can definitely ensure that the tree of life is safe and sound!

Of course, to be more secure, in order to ensure that there is no threat from powerful demonic beasts, Jia Zhengjin will also specially send several generals to patrol nearby to drive away and eliminate demonic beasts that enter this area. Maybe I'll have to ask Liv to help, it's safer to have her, a ninth-order powerhouse, to guard it!

The Tree of Life is really important to Jia Zhengjin, because the Spring of Life is related to the issue of longevity! Many strong people in this world have passed away at an important moment when they have crossed the ranks because of the problem of longevity. Some of them can obviously get a longer lifespan by breaking through the ninth order from the eighth order, but they fall before they successfully break through.

In addition to Jia Zhengjin's own and his family's use, the Fountain of Life can also be used to attract more masters of various races and enhance the strength of the Holy Dragon City!

Reaching level 17 earns 1 skill point, plus the Book of Skill Points he obtained earlier, Jia Zhengjin now has a total of two points that can be assigned.

He had already thought of a route to add some points, that is, to build a science laboratory as soon as possible, and then add some science and technology to make the Holy Dragon City develop better!

Now that the premise building of the science laboratory is only a mechanical factory, Jia Zhengjin did not hesitate to add the points and light up the icon of the science laboratory.

And the remaining skill point, of course, is decisively added to the science laboratory.

Successfully unlocked the Machine Factory and Science Lab, and two new blueprints appeared in the building slot. This meant that he would soon be able to build both buildings in the city.

It is useless for a short time to build a science laboratory, after all, all its technologies need points, unless Jia Zhengjin continues to upgrade, he can freely add points.

However, the machine factory is a good building, with which you can make a lot of simple machinery, and it is also the most important place to make robots in the later stage!

It seems that you should hurry up and upgrade your treasure and get as many skill points as possible to point up your science. But there have been so many things recently, especially the dark dragon is like a shadow that makes Jia Zhengjin depressed, and it is difficult to find time to concentrate on fighting monsters and upgrading! First of all, you have to recruit the right person to inherit Tangier's knowledge and magic, so that he can grow up to be able to fight the dark dragon, so as not to destroy this world and make himself have no fun in the future!

Just thinking about it, the ugly monster who had been sleeping on Jia Zhengjin's shoulder suddenly opened his eyes and flew directly into the air to make an ugly "quack" sound behind him, as if reminding him.

This ugly monster slept on Jia Zhengjin's shoulder all day long, and even after the fight was so fierce just now, it didn't wake up. Suddenly the reaction is so big, it seems that there is a problem!

Jia Zhengjin immediately waited for the battle, and at the same time quickly learned the flash skill book of the general category, just to increase his combat effectiveness!
