Blocking the vitality bomb of Tower 4, those few tree leaders not only did not have any loss, but got the nourishment of energy.

The next moment, a few long vines were like lightning bolts piercing the blue sky towards the iron tower No. 4 in the air.

"Humph!"

Tower No. 4 snorted coldly, didn't dodge, and directly punched it.

Boom!

An oncoming vine collided with a giant fist and immediately exploded like a bomb.

Immediately after several long vines, the No. 4 giant fist of the iron tower bombarded one after another, detonating them one by one.

A mechanical life with the peak strength of the ninth level naturally has his pride. The Genki bomb attack just now didn't work, and it already made Tower 4 feel very unhappy, and now he naturally refuses to run away easily.

However, the next moment, when more long vines rose into the air, Tower 4 no longer insisted.

Stretching out his hands, he attacked several miniature vitality bullets in a row, blasting the group of long vines apart, and after removing the threat, he immediately turned around and flew away.

Woo - the leaders of the treemen below watched the hateful "human" flee with angry expressions on their faces, but there was nothing they could do but vent their anger on the mechanical warriors all over the ground.

At this time, the situation on the battlefield was already extremely bad for the mechanical army.

The giant treants are as if they are unkillable, and the mechanical warriors are like small bugs in their eyes, ready to be ravaged at any time.

Zhang Feng looked at this scene and immediately couldn't sit still:

"Wang Qian, the battle at the obsidian mine belonging to the Bone Witch Tribe has ended, and the 40,000 troops can be mobilized. In addition, I have issued an order to the mechanical army on the battlefield of Wismar City, they have begun to assemble, and they will soon come through the base space wormhole to reinforce, ready to press the whole army up, and use the marine tactics of the mechanical army, even if you fill it with your life, you will also fill these tree people to death! Occupy the Valley of the Devil!"

"Master, subordinates have different suggestions. Wang Jian knelt on the ground and reported.

Mechanical life has its own mind, and everything is considered for the benefit of the inheritor. When the lineage does something wrong, they point it out.

Of course, if the inheritors insist on doing the wrong thing, they will not hesitate to carry out the order.

"Okay, you say!"

Wang Jian is a commanding intelligent life, and in many ways may be more comprehensive than he thinks, Zhang Feng is not an arrogant and ignorant person.

"Master, my subordinates suggest that we withdraw immediately. ”

"Tell me your reasons!" Zhang Feng didn't think that Wang Jian would be untargeted.

"Yes, master!" Wang Jian first agreed, and then spoke:

"Judging from the situation on the battlefield, the Treants have completely restrained our troops. Although our Demon Fighter has not yet appeared, even the Vitality Bomb of the Ninth Rank Peak Warrior cannot destroy them, and I believe that the Energy Bomb attack of the Demon Fighter will not do any better. Under these circumstances, if we reluctantly continue to fight, even if we win in the end, it will be a crushing victory. Originally, with the production speed of our mechanical army, as long as there are resources, we can create a large number of mechanical soldiers in a very short time, and we are not afraid of a miserable victory. However, our mechanical empire is now in a special period, and there are two external hidden dangers. First, the Dragon Island could be attacked at any time, and second, the powerful actions of the Bright Empire of mankind have turned our territory west of the Seine River into a buffer zone, and even dispatched the Rose Knights, in the name of assisting us in joint management, but in fact they are eyeing each other and choosing people to devour at any time. If our strength is weakened to a certain extent, the Empire of Light and the Empire of Stocanor will definitely not let go of this good opportunity. So, please think twice, the host. ”

Wang Jian spoke eloquently, explaining the battlefield situation and the political situation of the Machine Empire clearly.

Zhang Feng listened carefully. The mechanical empire was developed by him, and he is also very familiar with the surrounding situation, but if he withdraws his troops like this, he is still a little unwilling.

As if to understand the master's concerns, Wang Jian continued:

"As for the purple gold mine, please rest assured by the owner. The subordinates have already driven the No. 75 sub-base to the entrance of the mine, and after the hole was blown up, the space inside was very large, and the mineral engineering vehicles were working intensively to dig as much purple gold ore as possible. As long as we sacrifice the 10,000 mechanical army in the valley, hold off the attack of the treants, and buy a certain amount of time, we can mine enough purple gold ore. Sub-base evolution and manufacturing of Level 3 classes can no longer worry about lack of resources. ”

"Good! Well done!" Zhang Feng couldn't help but praise after listening to the plan.

Then, I quickly made up my mind:

"Execute your plan right away. ”

"Yes, master!"

Wang Jian agreed and began to lay out the battle plan.

Zhang Feng looked at the number of mechanical warriors in the Valley of Demons who were getting smaller and smaller, and said with a cold face:

"Okay! Treeman, let you run rampant now. When I find a way to restrain you, I'll let you know that the mechanical army can't be provoked. ”

............ In the obsidian mining cave belonging to the Bone Witch Tribe, the hole that was originally hidden under the giant tree has long been infinitely expanded by the mechanical army.

The No. 75 sub-base, which is more than ten meters high, rumbled to the entrance of the cave, and the mineral engineering vehicles were busy working, almost continuously dumping truckloads of purple gold ore into the hatch of the sub-base. The No. 75 sub-base teleported away these ores through the spatial wormhole in an instant.

In this way, if there is any accident, even if the No. 75 sub-base is destroyed, it will not cause the purple gold ore to suffer.

Zhang Feng paid a little attention to it, and knew that with the efficiency of these mineral engineering vehicles, in such a short period of time, the amount of capital mines excavated was already an astronomical amount, enough for all the sub-bases to be upgraded to level three, and to create a large number of level three troops.

Zhang Feng dispatched a five-level mining engineering vehicle, which has extremely high work efficiency, not only fast excavation speed, but also the function of storage space. This saves a lot of space and makes the size of the mineral engineering vehicle more comfortable.

Under this premise, the fifth-level mineral engineering vehicle can change its shape and size to adapt to the surrounding mining environment.

At present, twenty or thirty fifth-level mineral engineering vehicles are working intensively in the obsidian mine, and the locations are all within 200 meters from the cave entrance.

This obsidian mine cave is very magical, and it is very normal in the front cave, but when it reaches a depth of more than two hundred meters, it becomes chaotic, and no light can shine into it.

Zhang Feng transferred the Spy No. 1 back from the front line and asked him to probe the depths of the cave in the front cave, but the result was very disappointing.

As a reconnaissance-type mechanical life, the detection wave emitted by Spy 1 can easily penetrate the ninth-level magic barrier, and it can be said that everything is invisible within tens of kilometers. But there is nothing that can be done about these chaotic things.

This strengthened Zhang Feng's curiosity even more.

Of course, it was impossible for Zhang Feng to let Spy No. 1 venture into the cave. Not only because of the preciousness of ninth-level warriors, but also because mechanical beings are already real creatures, completely like human beings with their own emotions, it is impossible for Zhang Feng to completely use them as tools and take such risks.

But the average mechanical warrior is nothing. Like a mechanical warrior of level five or six or even seven or eight, they have no emotions in themselves, and if they are classified, they are closer to combat weapons.

Under Zhang Feng's order, the two seventh-level swift mechanical insects stepped into the chaos without fear.

To be on the safe side, Zhang Feng did not connect his consciousness with them, but let a sub-base transmit back the picture seen by the seventh-level swift mechanical insect through a signal.

The moment the swift mechanical worms stepped into the chaos, they immediately lost contact.

You know, these are two powerful seventh-level swift mechanical worms! Why did they disappear so silently?

In this instant, the two seventh-level swift mechanical insects were eliminated, and they had to be silent, and I am afraid that even the Holy Rank Arnold would have a certain degree of difficulty in doing it.

Zhang Feng frowned, this matter was really strange. Or rather, it's too weird.

Once you go deeper into the cave for more than 200 meters, no matter what you enter, you will immediately lose contact. What's going on?

When you think of the orc warriors guarding the mines, it seems that no one wants to approach here, and they all live and guard in the nearby caves. Here, there must be some secret.

Zhang Feng was still unwilling, and after thinking for a while, he once again commanded two seventh-level swift mechanical insects to come out, found a large iron cable several meters long and wrapped them together, and then ordered them to be one in front and one in the back, and cautiously walked towards the chaos.

After the first one walked in completely, Zhang Feng hurriedly ordered the latter to stop, and then let it turn around and pull the iron cable back.

In the midst of infinite anticipation, the iron rope was pulled back.

However, what is surprising is that the other end of the iron lock is empty, and there is nothing.

Things have come to this point, although Zhang Feng is very reluctant, but there is no way to do it.

At this time, the signal for communication sounds.

Wang Jian reported:

"Master, the front-line mechanical warriors have suffered heavy losses, and they can't stop the attack of the tree people. Optimistically, in a few more minutes, the Treants will attack near the mine. May I ask the master if the 75th sub-base will be evacuated immediately. If we evacuate now, we will be sure that we will succeed at more than 95 percent, and if we do not evacuate immediately, Sub-Base 75 will be in danger of being destroyed. ”

Zhang Feng thought for a moment and ordered:

"Don't evacuate! The mineral engineering truck will continue to mine, seize every second, and if it can mine one more kilogram, it will extract one more kilogram. ”

"Yes, master!"

Zhang Feng temporarily gave up the study of the secrets in the cave and set his sights on the battlefield picture.

I saw that the battle had come to an end.

Ten thousand mechanical warriors were almost killed and wounded. Many of the mechanical warriors were badly damaged, but they still dragged half of their mutilated mechs, fearlessly and futile in their suicidal attacks on the Treants.

As long as it is an order from the inheritor, they will not hesitate to carry it out.

Although in the strict sense, they can only be regarded as combat weapons, Zhang Feng is still a little moved.

...... Today will be the first day of the Fourth Watch! Rolling all over the ground and frantically begging for a monthly pass!
